From the article:
The commercial spaceflight company Golden Spike – which aims fly private missions to the moon by 2020 – has teamed up with the New York-based firm Honeybee Robotics to design robotic rovers for the planned lunar expeditions.
“We’re very proud to be working with Honeybee, which has tremendous experience and a record of successful performance in the development of flight systems for NASA,” Golden Spike President and CEO Alan Stern said in a statement last month.
Golden Spike first announced its goal of launching two-person commercial flights to the moon in December 2012. To boost the scientific output of the expeditions, the company plans to send unmanned rovers to the moon ahead of the crew to collect samples from a wider area than the crew will be able to travel from their landing pad. The rovers will then meet up with the crew’s spacecraft once it arrives, according to the mission plan. [Golden Spike’s Private Moon Mission Plan in Pictures]
“Honeybee brings a unique body of knowledge and skills to help us augment the capabilities of human exploration missions with advanced robotics,” Clive Neal, a researcher at the University of Notre Dame in Indiana and chair of Golden Spike’s lunar science advisory board, said in a statement. “Their participation is a key step forward in helping Golden Spike change the paradigm of human space exploration, through the development of highly capable lunar exploration system architecture for customers around the world.”
Honeybee Robotics has been designing planetary sampling devices for clients including NASA and the US Department of Defense for more than 25 years, and has contributed to the last three of NASA’s Mars landers: The company designed the rock abrasion tool for NASA’s Mars Exploration Rovers Spirit and Opportunity, as well as the icy soil acquisition device (or “Phoenix Scoop”) for the U.S. space agency’s Phoenix Mars lander, and the sample manipulation system and dust removal tool for the Curiosity rover.
Golden Spike officials initially priced the missions at $1.5 billion per person, but has since estimated that the cost could drop down to about $750 million with the help of media coverage and sales of merchandising rights of the missions, Stern told reporters last year at the 29th National Space Symposium in Colorado Spring, Colo. Potential moon flyers include leaders of nations, large corporations, and independently funded individuals.
The companies plan to complete preliminary tests of their rover design by mid-2014.
The cost of the landers and other equipment were the long poles in the tent of NASA’s old Constellation program.
It will be interesting to see if Golden Spike’s plan will work to bring these expenses down. I surely hope so.
The Mars One organization released this announcement on Tuesday:78,000 sign up for one-way mission to MarsAmersfoort, 7th May 2013 – Just two weeks into the nineteen week application period, more than seventy-eight thousand people have applied to the Mars One astronaut selection program in the hope of becoming a Mars settler in 2023.
Mars One has received applications from over 120 countries. Most applications come from USA (17324), followed by China (10241), United Kingdom (3581), Russia, Mexico, Brazil, Canada, Colombia, Argentina and India.
Bas Lansdorp, Mars One Co-Founder and CEO said: “With seventy-eight thousand applications in two weeks, this is turning out to be the most desired job in history. These numbers put us right on track for our goal of half a million applicants.”
“Mars One is a mission representing all humanity and its true spirit will be justified only if people from the entire world are represented. I’m proud that this is exactly what we see happening,” he said.
As part of the application every applicant is required to explain his/her motivation behind their decision go to Mars in an one minute video. Many applicants are choosing to publish this video on the Mars One website. These are openly accessible on applicants.mars-one.com.
“Applicants we have received come from a very wide range of personalities, professions and ages. This is significant because what we are looking for is not restricted to a particular background. From Round 1 we will take forward the most committed, creative, resilient and motivated applicants,” said Dr. Norbert Kraft, Mars One Chief Medical Officer.
Mars One will continue to receive online applications until August 31st 2013. From all the applicants in Round 1, regional reviewers will select around 50-100 candidates for Round 2 in each of the 300 geographic regions in the world that Mars One has identified.
Four rounds make the selection process, which will come to an end in 2015; Mars One will then employ 28-40 candidates, who will train for around 7 years. Finally an audience vote will elect one of groups in training to be the envoys of humanity to Mars.
I’m not surprised most of the applicants are from the U.S., but the number of applicants from China does a little bit.
Maybe it shouldn’t though, the Chinese maybe looking for lebensraum ( elbow room ), what with over a billion people and all.
Mars might be an appealing bit of real estate to them.
From America Space:
There have been occasional suggestions that NASA should scrap its Space Launch System (SLS) in favor of SpaceX’s Falcon Heavy for fulfilling its beyond low-Earth orbit needs . The claim forwarded by some is that the as-yet-untested-and-unflown 53 mt low-Earth orbit (LEO) (200 km @ 28°) Falcon Heavy is now “cheaper” than the as-yet-untested-and-unflown SLS. Furthermore, canceling the SLS would supposedly save NASA $10 billion—money that could otherwise be used to fund such programs as the Commercial Crew integrated Capability (CCiCap), to conduct a flight test of Orion on a Falcon Heavy, and to focus on building a small-scale space station in the area near the Moon. One issue not addressed by proponents of canceling SLS is whether it is a good idea to couple a nation’s human exploration spaceflight capabilities to a private company. An issue which appears to be altogether ignored, is the Falcon Heavy’s small lunar payload capability and the impact this would have on an already complex and risky endeavor such as lunar exploration.
According to SpaceX, the Falcon 9 Heavy, also called the Falcon Heavy, will have a 53 mt (metric ton) payload capacity to LEO of 200 km with an inclination of 28° . Such a LEO payload capability will be impressive, allowing SpaceX to launch nearly twice the payload of a Delta IV Heavy or an Atlas V, and to do so more cheaply than either. But when it comes to launching payload to a geostationary transfer orbit (GTO) or beyond, the Falcon 9 Heavy falls far short of either the Delta or Atlas launchers. With a GTO payload of barely over 12 mt, the Falcon 9 Heavy is at least 1 metric ton, or 1,000 kg, under what either the Delta IV Heavy or Atlas V can deliver to the same point in space.
The Falcon 9 Heavy is, much like United Launch Alliance’s Delta IV Heavy, a triple-bodied version of the company’s Falcon 9 launch vehicle. Photo Credit: SpaceX
The Falcon 9 Heavy’s GTO payload deficiency relative to the existing EELV launch vehicles has other down-stream effects as to its appropriateness for beyond-Earth orbit (BEO) crewed exploration. It is safe to assume that the Falcon Heavy’s low-lunar orbit (LLO) payload capacity will not top much above 10 mt . How will the Falcon 9 Heavy’s meager LLO payload capacity enable a meaningful return to the Moon? And why even talk about the Falcon Heavy as a possible launcher of crewed lunar exploration when each of the Delta IV Heavy and Atlas V launchers can send over 1,000 kg more than the Falcon Heavy to the Moon? Moreover, while the Delta IV and Atlas V have extensive flight histories, the Falcon Heavy has no such experience.
Advocates of using the Falcon Heavy don’t just want to rewrite who takes us beyond-Earth orbit, but more fundamentally how such missions are built. Reliance upon the Falcon Heavy for launching a beyond-Earth exploration program means some hard choices as to mission architecture. Traditionally, crewed exploration beyond low-Earth orbit has focused on minimizing complexity, and therefore risk and cost, by using a heavy-lift rocket (HLV). The logic behind using an HLV for lunar exploration in the past was that fewer launches correlated to less risk. The Falcon Heavy’s 10 mt capability means that any lunar exploration program will have to be one of assembling pieces/parts in low-Earth orbit, where the Falcon Heavy’s (LEO) 53 mt payload capacity can really shine. Some have claimed that centering a beyond-Earth exploration program on the Falcon Heavy does not mean ending the Orion spacecraft program. They point this out because Orion is the only spacecraft designed from the ground up for beyond-Earth exploration. Certainly, a Falcon Heavy can place an Orion crewed and service module in low-Earth orbit. But several additional launches will be needed to send Orion and her crew to the Moon. A lunar crewed mission using the Falcon Heavy would mean assembling, at necessary LEO locations, a crewed vehicle, a lander, a trans-lunar injection stage, a stage to get the crewed spacecraft and lander into LLO, and possibly a separate stage to enable the crewed spacecraft to return to Earth .
While supporters of an all-commercial approach frequently tout the company’s laudable accomplishments, they just as frequently ignore the limitations of both the Falcon Heavy launch vehicle and the Dragon spacecraft. Photo Credit: SpaceX
One problem with a non-HLV approach to lunar exploration is that if a replacement Falcon Heavy and payload are not handy, any launch failure could very well mean a scrubbed mission. So a non-HLV approach necessarily means an inventory of not just a spare Falcon Heavy, but of duplicate spaceflight hardware—or designing hardware and refueling stations such that a delay of weeks or months would have only a marginal impact on the mission. Solving all of these unknown-unknowns (or unk-unks in engineering speak) associated with multiple launches, assembling a mission in LEO, in-space refueling at an orbiting location, among others flowing from a non-HLV approach to beyond-Earth exploration, could see the cost advantage of using the relatively unproven Falcon Heavy largely, if not completely, evaporate.
A beyond-Earth exploration program using the Falcon Heavy in an HLV architecture has its own downsides and associated costs. In order to enable the Falcon 9 Heavy to be a capable beyond low-Earth orbit launcher, funds will certainly be needed to create a new cryogenic second-stage. This will be needed because, in its current configuration, a Falcon 9 Heavy could not even launch one 11.6 mt Unity node module, much less a 20 mt Bigelow BA 330 Nautilus module. Even with a brand new second-stage, reliance upon the Falcon 9 Heavy to build, visit, and maintain a lunar orbiting outpost will dictate doing so in very small chunks; the number of launches will then begin to add-up, as will the complexity, risk, and cost. A Falcon Heavy cannot place an Orion spacecraft even in high-Earth, much less lunar, orbit. So reliance upon the Falcon 9 Heavy for beyond low-Earth missions in an HLV-based lunar mission architecture would only set NASA up to cancel Orion and go with Dragon for our nation’s crewed space exploration needs.
While it may be true that the Dragon spacecraft has a heatshield capable of allowing the spacecraft safe reentry into the Earth’s atmosphere, little else of Dragon is crew, much less lunar mission, capable. SpaceX’s Dragon is currently a participant in NASA’s commercial crew and cargo programs. One goal of NASA’s commercial crew program is to enable spacecraft built and operated by commercial space companies to get crews to and from the International Space Station by late 2017. But the requirements for a crewed spacecraft tailored for low-Earth orbit are different than those for beyond-Earth orbit. For one, a LEO capable spacecraft need only be capable of hours of operation, where a lunar spacecraft needs a capability of days. This means that the use of the Falcon Heavy as a means to returning humans to the Moon very likely means funding further enhancements, and verifying those enhancements to the Dragon spacecraft. As with over 90 percent of the funding for Falcon 9 and Dragon, this additional financial burden would fall upon NASA’s, and therefore the U.S. taxpayer’s, shoulders. Even with an enhanced Falcon Heavy launcher and Dragon spacecraft, more than one Falcon Heavy launch would still be needed to support a crewed lunar landing mission. Several Falcon Heavy launches would be needed to build a lunar orbiting outpost.
NASA’s SLS has the full support, to include funding, of Congress. As such, efforts to cancel the system in lieu of one that favors the company that SpaceX supporters approve of is not likely to occur. Image Credit: NASA
Or NASA could send a crewed lunar mission or build a lunar outpost with far fewer SLS launches. That’s because the very first iteration of the SLS, the Block I, will carry twice the payload of a Falcon Heavy to the Moon. The SLS Block II will have a lunar payload capacity nearly 3–4 times that of the Falcon Heavy, depending upon what engines are selected for the SLS’s advanced booster.
Beyond the SLS’s substantial payload advantage for lunar missions, the question of cost remains. Are 3 or 4 Falcon Heavy launches really cheaper than just one SLS Block II launch? That is a hard question to answer given that both launchers are still effectively “paper” rockets. In factoring launch costs, there is the cost of the launch vehicle, the launch pad, launch support, and post-launch management, just to name a few.
The bigger problem for those wishing to end the Space Launch System program is that it is currently ahead of schedule. According to John Elbon, Boeing VP & General Manager, Space Exploration, “We’re on budget, ahead of schedule. There’s incredible progress going on with that rocket” . Canceling a rocket that is ahead of schedule would be difficult at best. Given that Congress has, over three votes, not only supported SLS but increased its funding over amounts sought by the Obama Administration, the odds of opponents getting SLS canceled are slim-to-none.
Space Launch System opponents suggest that the SLS program should cancel until a mission requiring such a rocket is identified. John Shannon, also with Boeing, recently stated, “This ‘SLS doesn’t have a mission’ is a smokescreen that’s been put out there by people who would like to see that [program’s] budget go to their own pet projects. SLS is every mission beyond low Earth orbit. The fact that NASA has not picked one single mission is kind of irrelevant” . It bears mentioning that a good part of the reason there is no meaningful mission for the Orion-SLS is because the Obama Administration has not agreed with Congress that, as Congress noted in its 2010 NASA Authorization Act, cislunar space is the next step in our efforts beyond Earth and that the SLS is an integral part of that step.
Moreover, both short- and long-term missions for SLS have emerged in recent months. Within the 2014 FY Budget Proposal Request, NASA was directed to retrieve an asteroid, place it in lunar orbit, and then send astronauts to study it. The vehicle of choice is SLS. During a recent interview, NASA Deputy Associate Administrator for Exploration Systems in the Human Exploration and Operations Mission Directorate Dan Dumbacher stated on AmericaSpace that the long-term mission for SLS was to send astronauts to Mars.
Mr. Jillhouse sings the acolades of the Space Launch System as others sing them about SpaceX’s Falcon9 rockets. What he fails to mention is the SLS’s massive program slippages and muti-billion dollar cost overruns, versus commercial’s million dollar overruns and schedule slippages. It’s not even in the same ballgame, let alone ballpark.
Also the point should be that NASA should’ve bid the SLS job out in order to save the taxpayers money, but the function of SLS isn’t primarily for beyond Earth orbit exploration.
It’s to provide jobs in states that have NASA centers. And that’s why these projects are perpetually underfunded, just enough money is sent in order to keep people employed as long as the politicians can make it possible.
Maybe in the end the SLS will get finished and work as advertised. If I live long enough.
Orbital Sciences Corporation Sunday launched its Antares rocket at 05:00 p.m. EDT from the new Mid-Atlantic Regional Spaceport Pad-0A at the agency’s Wallops Flight Facility in Virginia.
The test flight was the first launch from the pad at Wallops and was the first flight of Antares, which delivered the equivalent mass of a spacecraft, a so-called mass simulated payload, into Earth’s orbit.
“Today’s successful test marks another significant milestone in NASA’s plan to rely on American companies to launch supplies and astronauts to the International Space Station, bringing this important work back to the United States where it belongs,” said NASA Administrator Charles Bolden. “Congratulations to Orbital Sciences and the NASA team that worked alongside them for the picture-perfect launch of the Antares rocket. In addition to providing further evidence that our strategic space exploration plan is moving forward, this test also inaugurates America’s newest spaceport capable of launching to the space station, opening up additional opportunities for commercial and government users.
“President Obama has presented a budget for next year that ensures the United States will remain the world leader in space exploration, and a critical part of this budget is the funding needed to advance NASA’s commercial space initiative. In order to stop outsourcing American space launches, we need to have the President’s budget enacted. It’s a budget that’s good for our economy, good for the U.S. Space program — and good for American taxpayers.”
The test of the Antares launch system began with the rocket’s rollout and placement on the launch pad April 6, and culminated with the separation of the mass simulator payload from the rocket.
The completed flight paves the way for a demonstration mission by Orbital to resupply the space station later this year. Antares will launch experiments and supplies to the orbiting laboratory carried aboard the company’s new Cygnus cargo spacecraft through NASA’s Commercial Resupply Services (CRS) contract.
“Today’s successful test flight of Orbital Sciences’ Antares rocket from the spaceport at Wallops Island, Virginia, demonstrates an additional private space-launch capability for the United States and lays the groundwork for the first Antares cargo mission to the International Space Station later this year,” said John Holdren, director of the Office of Science and Technology Policy. “The growing potential of America’s commercial space industry and NASA’s use of public-private partnerships are central to President Obama’s strategy to ensure U.S. leadership in space exploration while pushing the bounds of scientific discovery and innovation in the 21st century. With NASA focusing on the challenging and exciting task of sending humans deeper into space than ever before, private companies will be crucial in taking the baton for American cargo and crew launches into low-Earth orbit.
“I congratulate Orbital Sciences and the NASA teams at Wallops, and look forward to more groundbreaking missions in the months and years ahead.”
Orbital is building and testing its Antares rocket and Cygnus spacecraft under NASA’s Commercial Orbital Transportation Services (COTS) program. After successful completion of a COTS demonstration mission to the station, Orbital will begin conducting eight planned cargo resupply flights to the orbiting laboratory through NASA’s $1.9 billion CRS contract with the company.
NASA initiatives, such as COTS, are helping to develop a robust U.S. commercial space transportation industry with the goal of achieving safe, reliable and cost-effective transportation to and from the International Space Station and low-Earth orbit. NASA’s Commercial Crew Program also is working with commercial space partners to develop capabilities to launch U.S. astronauts from American soil in the next few years.
Although Orbital had to reschedule three times, they got their test launch off.
Let’s hope they solved their fairing separation issues before the main Cygnus missions start.
NASA’s first manned outpost in deep space may be a repurposed rocket part, just like the agency’s first-ever astronaut abode in Earth orbit.
With a little tinkering, the upper-stage hydrogen propellant tank of NASA’s huge Space Launch System rocket would make a nice and relatively cheap deep-space habitat, some researchers say. They call the proposed craft “Skylab II,” an homage to the 1970s Skylab space station that was a modified third stage of a Saturn V moon rocket.
“This idea is not challenging technology,” said Brand Griffin, an engineer with Gray Research, Inc., who works with the Advanced Concepts Office at NASA’s Marshall Space Flight Center in Huntsville, Ala.
“It’s just trying to say, ‘Is this the time to be able to look at existing assets, planned assets and incorporate those into what we have as a destination of getting humans beyond LEO [low-Earth orbit]?'” Griffin said Wednesday (March 27) during a presentation with NASA’s Future In-Space Operations working group.
A roomy home in deep space
NASA is developing the Space Launch System (SLS) to launch astronauts toward distant destinations such as near-Earth asteroids and Mars. The rocket’s first test flight is slated for 2017, and NASA wants it to start lofting crews by 2021.
The SLS will stand 384 feet tall (117 meters) in its biggest (“evolved”) incarnation, which will be capable of blasting 130 metric tons of payload to orbit. Its upper-stage hydrogen tank is big, too, measuring 36.1 feet tall by 27.6 feet wide (11.15 m by 8.5 m).
The tank’s dimensions yield an internal volume of 17,481 cubic feet (495 cubic m) — roughly equivalent to a two-story house. That’s much roomier than a potential deep-space habitat derived from modules of the International Space Station (ISS), which are just 14.8 feet (4.5 m) wide, Griffin said.
The tank-based Skylab II could accommodate a crew of four comfortably and carry enough gear and food to last for several years at a time without requiring a resupply, he added. Further, it would launch aboard the SLS in a single piece, whereas ISS-derived habitats would need to link up multiple components in space.
Because of this, Skylab II would require relatively few launches to establish and maintain, Griffin said. That and the use of existing SLS-manufacturing infrastructure would translate into big cost savings — a key selling point in today’s tough fiscal climate.
“We will have the facilities in place, the tooling, the personnel, all the supply chain and everything else,” Griffin said.
He compared the overall concept with the original Skylab space station, which was built in a time of declining NASA budgets after the boom years of the Apollo program.
Skylab “was a project embedded under the Apollo program,” Griffin said. “In many ways, this could follow that same pattern. It could be a project embedded under SLS and be able to, ideally, not incur some of the costs of program startup.”
There has been much caterwauling in the space advocacy community about the Space Launch System ( ne, “The Senate Launch System” ) concerning its cost and lack of purpose and/or destinations.
Of course, the thing was designed by Congress in order to fund a jobs program in the NASA Centers for the good voters of those districts. But it’s a seriously underfunded program, with just enough money to keep the civil servants of NASA employed, with just enough contractor support to keep them happy.
In the meantime, ideas like Skylab II, the Spacehab at EML-2 and the asteroid capture scheme rear their ugly heads and claim they’re economical in these austeric times.
My money is still on Elon Musk, Bob Bigelow, Dennis Tito and company.
From Centauri Dreams:
Existential risks, as discussed here yesterday, seem to be all around us, from the dangers of large impactors to technologies running out of control and super-volcanoes that can cripple our civilization. We humans tend to defer thinking on large-scale risks while tightly focusing on personal risk. Even the recent events near Chelyabinsk, while highlighting the potential danger of falling objects, also produced a lot of fatalistic commentary, on the lines of ‘if it’s going to happen, there’s nothing we can do about it.’ Some media outlets did better than others with this.
Risk to individuals is understandably more vivid. When Apollo 8 left Earth orbit for the Moon in 1968, the sense of danger was palpable. After all, these astronauts were leaving an orbital regime that we were beginning to understand and were, by the hour, widening the distance between themselves and our planet. But even Apollo 8 operated within a sequenced framework of events. Through Mercury to Gemini and Apollo, we were building technologies one step at a time that all led to a common goal. No one denied the dangers faced by every crew that eventually went to the Moon, but technologies were being tested and refined as the missions continued.
Inspiration Mars is proposing something that on balance feels different. As described in yesterday’s news conference (see Millionaire plans to send couple to Mars in 2018. Is that realistic? for more), the mission would be a flyby, using a free return trajectory rather than braking into Martian orbit. The trip would last 501 days and would be undertaken by a man and a woman, probably a middle-aged married couple. Jonathan Clark, formerly of NASA and now chief medical officer for Inspiration Mars, addresses the question of risk head-on: “The real issue here is understanding the risk in an informed capacity – the crew would understand that, the team supporting them would understand that.” Multi-millionaire Dennis Tito, a one-time space tourist who heads up Inspiration Mars, says the mission will launch in 2018.
Image: A manned Mars flyby may just be doable. But is the 2018 date pushing us too hard? Image credit: NASA/JPL.
We’ll hear still more about all this when the results of a mission-feasibility study are presented next weekend at the 2013 IEEE Aerospace Conference in Montana. Given the questions raised by pushing a schedule this tightly, there will be much to consider. Do we have time to create a reliable spacecraft that can offer not only 600 cubic feet of living space but another 600 for cargo, presumably a SpaceX Dragon capsule mated to a Bigelow inflatable module? Are we ready to expose a crew to interplanetary radiation hazards without further experience with the needed shielding strategies? And what of the heat shield and its ability to protect the crew during high-speed re-entry at velocities in the range of 50,000 kilometers per hour?
For that matter, what about Falcon Heavy, the launch vehicle discussed in the feasibility analysis Inspiration Mars has produced for the conference? This is a rocket that has yet to fly.
No, this doesn’t feel much like Apollo 8. It really feels closer to the early days of aviation, when attention converged on crossing the Atlantic non-stop and pilots like Rene Fonck, Richard Byrd, Charles Nungesser and Charles Lindbergh queued up for the attempt. As with Inspiration Mars, these were privately funded attempts, in this case designed to win the Orteig Prize ($25,000), though for the pilots involved it was the accomplishment more than the paycheck that mattered. Given the problems of engine reliability at the time, it took a breakthrough technology — the Wright J-5C Whirlwind engine — to get Lindbergh and subsequent flights across.
Inspiration Mars is looking to sell media rights and sponsorships as part of the fund-raising package for the upcoming mission, which is already being heavily backed by Tito. I’m wondering if there is a breakthrough technology equivalent to the J-5C to help this mission along, because everything I read about it makes it appear suicidal. The 2018 date is forced by a favorable alignment between Mars and the Earth that will not recur until 2031, so the haste is understandable. The idea is just the kind of daring, improbable stunt that fires the imagination and forces sudden changes in perspective, and of course I wish it well. But count me a serious skeptic on the question of whether this mission will be ready to fly on the appointed date.
And if it’s not? I like the realism in the concluding remarks of the feasibility study:
A manned Mars free-return mission is a useful precursor mission to other planned Mars missions. It will develop and demonstrate many critical technologies and capabilities needed for manned Mars orbit and landing missions. The technology and other capabilities needed for this mission are needed for any future manned Mars missions. Investments in pursuing this development now would not be wasted even if this mission were to miss its launch date.
Exactly so, and there would be much development in the interim. The study goes on:
Although the next opportunity after this mission wouldn’t be for about another 13 years, any subsequent manned Mars mission would benefit from the ECLSS [Environmental Control and Life Support System], TPS [Thermal Protection System], and other preparation done for this mission. In fact, often by developing technology early lessons are learned that can reduce overall program costs. Working on this mission will also be a means to train the skilled workforce needed for the future manned Mars missions.
These are all good reasons for proceeding, leaving the 2018 date as a high-risk, long-shot option. While Inspiration Mars talks to potential partners in the aerospace industry and moves ahead with an eye on adapting near-Earth technologies for the mission, a whiff of the old space race is in the air. “If we don’t fly in 2018, the next low-hanging fruit is in ’31. We’d better have our crew trained to recognize other flags,” Tito is saying. “They’re going to be out there.”
In 1968, faced with a deadline within the decade, NASA had to make a decision on risk that was monumental — Dennis Tito reminded us at the news conference that Apollo 8 came only a year after the first test launch of the Saturn 5. Can 2018 become as tangible a deadline as 1970 was for a nation obsessed with a Moon landing before that year? If so, the technologies just might be ready, and someone is going to have to make a white-knuckle decision about the lives of two astronauts. If Inspiration Mars can get us to that point, that decision won’t come easy, but whoever makes it may want to keep the words of Seneca in mind: “It is not because things are difficult that we dare not venture. It is because we dare not venture that they are difficult.”
There are a lot of nay-sayers out yonder decrying Tito’s idea as suicidal and a waste of money. But as recently as a couple of months ago questionnaires were sent out asking for volunteers to sign up for a one way trip to Mars (Mars One), even if there’s a better than even chance of dying at any moment of it.
The results were astounding.
Tito’s idea of sending an older married couple is nothing short of public opinion genius and if successful, could be the format of any future Mars colonization efforts.
Not to mention the technologies needed for the crossing.
NASA Deputy Administrator Lori Garver announced Wednesday a newly planned addition to the International Space Station that will use the orbiting laboratory to test expandable space habitat technology. NASA has awarded a $17.8 million contract to Bigelow Aerospace to provide a Bigelow Expandable Activity Module (BEAM), which is scheduled to arrive at the space station in 2015 for a two-year technology demonstration.
“Today we’re demonstrating progress on a technology that will advance important long-duration human spaceflight goals,” Garver said. “NASA’s partnership with Bigelow opens a new chapter in our continuing work to bring the innovation of industry to space, heralding cutting-edge technology that can allow humans to thrive in space safely and affordably.”
The BEAM is scheduled to launch aboard the eighth SpaceX cargo resupply mission to the station contracted by NASA, currently planned for 2015. Following the arrival of the SpaceX Dragon spacecraft carrying the BEAM to the station, astronauts will use the station’s robotic arm to install the module on the aft port of the Tranquility node.
After the module is berthed to the Tranquility node, the station crew will activate a pressurization system to expand the structure to its full size using air stored within the packed module.
During the two-year test period, station crew members and ground-based engineers will gather performance data on the module, including its structural integrity and leak rate. An assortment of instruments embedded within module also will provide important insights on its response to the space environment. This includes radiation and temperature changes compared with traditional aluminum modules.
“The International Space Station is a uniquely suited test bed to demonstrate innovative exploration technologies like the BEAM,” said William Gerstenmaier, associate administrator for human exploration and operations at NASA Headquarters in Washington. “As we venture deeper into space on the path to Mars, habitats that allow for long-duration stays in space will be a critical capability. Using the station’s resources, we’ll learn how humans can work effectively with this technology in space, as we continue to advance our understanding in all aspects for long-duration spaceflight aboard the orbiting laboratory.”
Astronauts periodically will enter the module to gather performance data and perform inspections. Following the test period, the module will be jettisoned from the station, burning up on re-entry.
The BEAM project is sponsored by NASA’s Advanced Exploration Systems (AES) Program, which pioneers innovative approaches to rapidly and affordably develop prototype systems for future human exploration missions. The BEAM demonstration supports an AES objective to develop a deep space habitat for human missions beyond Earth orbit.
A $17.8M contract is chump change for an I.S.S. article, but then again it’s only a test stand.
Bigelow plans on selling these things to countries like Japan and England who might want their own space stations on the cheap.
Maybe Golden Spike will buy a couple for a future Moon Base?
Stanford researchers in collaboration with NASA JPL and MIT have designed a robotic platform that involves a mother spacecraft deploying one or several spiked, roughly spherical rovers to the Martian moon Phobos.
Measuring about half a meter wide, each rover would hop, tumble and bound across the cratered, lopsided moon, relaying information about its origins, as well as its soil and other surface materials.
Developed by Marco Pavone, an assistant professor in Stanford’s Department of Aeronautics and Astronautics, the Phobos Surveyor, a coffee-table-sized vehicle flanked by two umbrella-shaped solar panels, would orbit around Phobos throughout the mission. The researchers have already constructed a prototype.
The Surveyor would release only one hedgehog at a time. Together, the mothership and hedgehogs would work together to determine the hedgehog’s position and orientation. Using this information, they would map a trajectory, which the mother craft would then command the hedgehog to travel.
In turn, the spiky explorers would relay scientific measurements back to the Phobos Surveyor, which would forward the data to researchers on Earth. Based on their analysis of the data, the scientists would direct the mothership to the next hedgehog deployment site.
An entire mission would last two to three years. Just flying to Phobos would take the Surveyor about two years. Then the initial reconnaissance phase, during which the Surveyor would map the terrain, would last a few months. The mothership would release each of the five or six hedgehogs several days apart, allowing scientists enough time to decide where to release the next hedgehog.
For many decisions, Pavone’s system renders human control unnecessary. “It’s the next level of autonomy in space,” he said.
The synergy between the Phobos Surveyor and the hedgehogs would also be reflected in their sharing of scientific roles. The Surveyor would take large-scale measurements, while the hedgehogs would gather more detailed data. For example, the Surveyor might use a gamma ray or neutron detector to measure the concentration of various chemical elements and compounds on the surface, while the hedgehogs might use microscopes to measure the fine crevices and fissures lining the terrain.
Although scientists could use the platform to explore any of the solar system’s smaller members, including comets and asteroids, Pavone has designed it with the Martian moon Phobos in mind.
An analysis of Phobos’ soil composition could uncover clues about the moon’s origin. Scientists have yet to agree on whether Phobos is an asteroid captured by the gravity of Mars or a piece of Mars that an asteroid impact flung into orbit. This could have deep implications for our current understanding of the origin and evolution of the solar system, Pavone said.
To confirm Phobos’ origins, Pavone’s group plans to deploy most of the hybrids near Stickney Crater. Besides providing a gravity “sweet spot” where the mother craft can stably hover between Mars and Phobos, the crater also exposes the moon’s inner layers.
A human mission to Mars presents hefty challenges, mainly associated with the planet’s high gravity, which heightens the risk of crashing during takeoffs and landings. The large amounts of fuel needed to overcome Mars’ strong pull during takeoffs could also make missions prohibitively expensive.
But Phobos’ gravity is a thousand times weaker than on Mars. If Phobos did indeed originate from the red planet, scientists could study Mars without the dangers and costs associated with its high gravity simply by sending astronauts to Phobos. They could study the moon itself or use it as a base station to operate a robot located on Mars. The moon could also serve as a site to test technologies for potential use in a human mission to the planet.
“It’s a piece of technology that’s needed before any more expensive type of exploration is considered,” Pavone said of the spacecraft-rover hybrid. “Before sampling we need to know where to land. We need to deploy rovers to acquire info about the surface.”
These probes could be precursors to a sample return mission. A promising area to dig determined beforehand would cut down on cost and wear and tear.
But these rovers could be used on their own for private industry, such as Google Maps in order to give ( and sell ) accurate virtual reality tours to Millenials who wish to sit in their livingrooms and explore Mars safely.
A true pre-Singularity technology.
Given the “big bang” of exoplanet discoveries over the past decade, I predict that there is a reasonable chance a habitable planet will be found orbiting the nearest star to our sun, the Alpha Centauri system. Traveling at just five percent the speed of light, a starship could get there in 80 years.
One Earth-sized planet has already been found at Alpha Centauri, but it is a molten blob that’s far too hot for life as we know it to survive.
The eventual discovery of a nearby livable world will turbo-boost interest and ignite discussions about sending an artificially intelligent probe to investigate any hypothetical life forms there.
But no nation will be capable of paying the freight for such a mission. Building a single starship would be orders of magnitude more expensive than the Apollo moon missions. And, the science goals alone could not justify the cost/benefit of undertaking such a gigaproject. Past megaprojects, such as Apollo and the Manhattan Project, could be justified by their promise of military supremacy, energy independence, support of the high tech industry or international prestige. The almost altruistic “we boldly go for all mankind” would probably stop an interstellar mission in its tracks.
The enormous risk and cost for starship development aside, future nations would also be preoccupied with competing gigaprojects that promise shorter term and directly useful solutions — such as fusion power plants, solar power satellites, or even fabrication of a subatomic black hole. However, the discovery of an extraterrestrial civilization at Alpha Centauri could spur an international space race to directly contact them and possibly have access to far advanced alien technology. (Except that it would take far advanced technology to get there in the first place!)
Microsystem technologist Frederik Ceyssens proposes that there should be a grassroots effort to privately organize and finance an interstellar mission. This idea would likely be received with delight at Star Trek conventions everywhere.
What’s the motivation for coughing up donations for an interstellar mission? Ceyssens says the single inspiring goal would be to establish a second home planet for humanity and the rest of Earth’s life forms by the end of the millennium. Such a project might be called “Ark II.”
“It could be our privilege to be able to lay the foundation of a something of unfathomable proportions,” Ceyssens writes.
He envisions establishing an international network of non-governmental organizations focused on private and public fundraising for interstellar exploration. The effort would be a vastly scaled up version of the World Wildlife Fund for Nature.
“Existing space advocacy organizations such as the Planetary Society or the British Interplanetary Society could play a central role in establishing the initiative, and gain increased momentum,” Ceyssens says. He proposes establishing a Noble foundation or a government wealth fund that can be fed with regular donations over, literally, an estimated 300 years it would take to have the bucks and technology to build a space ark.
ANALYSIS: Uniting the Planet for a Journey to Another Star
This slow and steady approach would avoid having a single generation make huge donations to the cause. Each consecutive generation would contribute some intellectual and material resources. A parallel can be found in the construction of the great cathedrals in late medieval Europe. An incentive might be that one of the distance descendants of each of the biggest donors is guaranteed a seat on the colonization express.
Unlike the British colonies in the great Age of Discovery, it is impractical to think of another star system as an outpost colony that can trade with Imperial Earth. There is no financial potential to investors.
Comparing an interstellar voyage to building cathederals because it could be a multi-generation project is a valid point, although it doesn’t seem to take into account advancing technology in robotics and rocket propulsion that can shorten the time needed to construct such a mission.
Actually, I wouldn’t be a bit surprised if another Earth-type world was discovered at Alpha Centauri, an interstellar mission would be mounted by the end of the 21st Century by a James Cameron-type and it wouldn’t take 80 years to get there either!

Would you go on an one way interstellar trip to Alpha Centauri? ( Or Proxima if planets were found there? )
The question was put out to the public about one way trips to Mars recently, but interstellar travel is an entirely different animal due to the infinitely longer distances and travel times involved.
But according to Paul Gilster on the Centauri Dreams web site, filling a crew roster might not be a problem:
If you were offered a chance to make an interstellar journey, would you take it? How about a garden-variety trip to low-Earth orbit? I’m often asked questions like this when I make presentations to the public, and I have no hesitation in saying no. Though I’m no longer doing any flight instructing, I used to love flying airplanes, but getting into a rocket and being propelled anywhere is not for me. To each his own: I’m fascinated with deep space and hope many humans go there, and you can count on me to write about their missions and robotic ones as well while keeping my office right here on Earth.
The point is, the percentage of people who actually go out and take the incredible journeys and fly the dangerous missions is vanishingly low. But throughout history, there have always been a few intrepid souls who were willing to get into the canoes or the caravels or the biplanes and open up new territories and technologies. Thank God we have the Neil Armstrongs and Sergei Krikalyovs of this world. And somewhere in England there are the relatives of some young 18th Century adventurer who signed up as a cabin boy and wound up living out his life in Australia. People like this drive the species forward and put into action the yearning for exploration I suspect we all share.
I’ve told this story before, but in the past few weeks a high percentage of the people coming to this site are coming for the first time, so I’ll tell it again. Robert Forward was the scientist who more than any other argued that we study methods for reaching the stars, saying that it could be done without violating the laws of physics and would therefore one day occur. Forward’s son Bob told me what happened one night at dinner when he asked his father whether he would get on a starship if it landed nearby and he was asked to go out and explore the universe, with the proviso that he could never come back. Forward’s response was instantaneous: “Of course!”
To which his wife Martha could only reply: “What about us? You mean you would just leave your family and disappear into the universe?” That made Forward pensive for only a moment as he replied, “You have to understand. This is what I have dreamed about all my life.”
To be fair, if an Earth-type world was ever found at Alpha Centauri, the chances of ever traveling there would be extremely low. It’s just plain cheaper to build super-telescopes to zoom in and literally “scope-out” any kind of life forms and biospheres there. No environmental issues, no contamination and no astronauts need apply.
The only way a planet at Alpha Centauri will be touched by human beings is like in James Cameron’s ‘Avatar.’ An “unobtainium” element with extraordinary abilities would have to be found that would make the time, effort and investments cost-effective to exploit.
As in Solar System exploitation, the reasons to explore extra-solar worlds would have to involve a strong economic element. Even personal freedoms comes in at a distant second.
