New Dates for Final Shuttle Launches

Article Updated: 26 Apr , 2016



If you are tentatively planning to attend one of the final shuttle launches, the uncertainty on launch dates just got a bit more certain; plus — an added benefit — we won’t see the end of the shuttle program until 2011.

NASA announced new target dates for the final two (and maybe three) shuttle missions. STS-133 is now aiming for November 1, 2010 at approximately 4:33 p.m. EDT for the final flight of shuttle Discovery, and for STS-134, February 26, 2011 at around 4:19 p.m. EST for shuttle Endeavour’s last launch. The potential bonus mission STS-135, would launch sometime in August 2011, if approved by Congress and NASA. The latest word on that was that NASA officials hope the decision would be made sometime this month.

The target dates were changed because the Alpha Magnetic Spectrometer instrument, heading for installation on the International Space Station won’t be ready by the time of the previously planned Sept. 16 launch for STS-133. With that launch moving to November, STS-134 cannot fly as planned, so the next available launch window — taking into account sun angles and other planned launches –is in February 2011.

These dates were rumored last week, but this is now the official word. However, of course, all target launch dates are subject to change.

The last external tanks for the STS-134 mission was recently completed at the Michoud Assembly Facility in New Orleans. There will be a final farewell ceremony at 9 a.m. CDT on Thursday, July 8, which will be shown on NASA TV. The event will commemorate 37 years of successful tank deliveries and the final external tank’s rollout for the last space shuttle flight. Coverage begins at 8:45 a.m.

The tank, designated ET-138, will travel on a wheeled transporter one mile to the Michoud barge dock. It will be accompanied by the Storyville Stompers, a traditional area brass band, and hundreds of handkerchief-waving employees in typical New Orleans fashion and spirit.

The tank will travel on a 900-mile sea journey to NASA’s Kennedy Space Center in Florida, where it will support shuttle Endeavour’s STS-134 launch. No word yet on how the oil spill may affect the journey.

Another tank that was damaged in Hurricane Katrina is being refurbished for the Launch-On-Need (LON) rescue mission STS-335, which if not needed and if it gets approval to fly as the actual final shuttle mission, (Atlantis) would change to STS-135.

Eh, the AMS was (and still is) planned for the STS-134 mission. Delays in STS-133 and design changes in AMS led to the revised launch schedule.

A constant source of amusement are the usually slothful politicians who snap into life once they see an opportunity to exploit unrelated events that might somehow support their re-election agenda. ref: Hutchison Pleased with Short-Term Shuttle Extension to 2011 – Calls Move “An Important First Step” . What the Senator claims is an “extension” is actually a forced delay due solely to further mismanaged delivery of the $1.5 billion 6,700kg AMS-2 instrument. The much delayed AMS-2, originally intended for external installation aboard ISS by 2003, has eventually been re-manifested all the way to the very last scheduled Shuttle flight possible, previously set for late 2010. True to form the AMS-2, which electively underwent a late reconfiguration from an… Read more »
