This just in from Alan Boyle’s Cosmic Log:
Technicians work on the space shuttle Discovery inside Orbiter Processing Facility 3 at NASA’s Kennedy Space Center in Florida, in preparation for a flight that is due for launch this fall. Discovery’s flight is the next shuttle mission on NASA’s schedule.
Managers of NASA’s space shuttle program are seeking a shift in the launch schedule that would delay the fleet’s final launch until February 2011 at the earliest.
The schedule shift would have the shuttle Discovery to lift off on Oct. 29 instead of Sept. 16, and schedule Endeavour’s flight for no earlier than Feb. 28, 2011, rather than in November as previously scheduled. Managers asked for the shift this afternoon in a “Change of Launch” request issued to all invoved in those two flights, according to Jay Barbree, NBC News’ Cape Canaveral correspondent.
Discovery is to deliver the Italian-built Leonardo logistics module to the International Space Station and install it as a permanent addition to the complex. Endeavour will bring up the $1.5 billion Alpha Magnetic Spectrometer, an international physics experiment.
“These two flights will be the last for the space shuttle fleet unless a plan to launch space shuttle Atlantis on a full-up supply run a year from now is approved,” Barbree says.
NASA is already getting Atlantis ready as a backup rescue shuttle in case something goes wrong during Endeavour’s mission. Assuming that Atlantis isn’t needed for an unprecedented rescue, NASA has been talking about using that shuttle and a minimal crew to deliver more supplies to the station in mid-2011. Members of Congress are likely to be amenable to that plan.
NASA public affairs officials said they could not comment on Barbree’s report but noted that schedule changes have been under discussion for weeks. The factors that could contribute to a delay include the need to retrofit the Alpha Magnetic Spectrometer for a longer stint on the space station, the potential for a space traffic jam involving Russian or Japanese supply craft, and the limited number of opportunities for launch due to unfavorable sun angles.
NASASpaceflight.com has been following the discussions over the space agency’s shuttle manifest like a hawk, and we’ll pass along any further information about the shuttle schedule as it becomes available.
The trick to this is funding, either from NASA’s FY2011 (that hasn’t been passed yet) or from a Continuing Resolution of FY2010.
I think the Congress-critters will pass this.
