The main objective of STS-61-F was to deploy the Ulysses solar probe, which would travel to Jupiter and use it as a gravitational slingshot in order to be placed into polar orbit around the Sun. This mission would have marked the first use of the Centaur-G liquid-fueled payload booster, which would also be used on the subsequent mission to send ...
With its very heavy workload, the STS-61 mission was one of the most complex in the Shuttle's history. STS-61 lasted almost 11 days, and crew members made five spacewalks (extravehicular activities (EVAs)), an all-time record; even the re-positioning of Intelsat VI on STS-49 in May 1992 required only four. The flight plan allowed for two ...
The codes were adopted from STS-41-B through STS-51-L (although the highest code used was actually STS-61-C), and the sequential numbers were used internally at NASA on all processing paperwork. After the Challenger disaster , NASA returned to using a sequential numbering system, with the number counting from the beginning of the STS program.
The mission lasted a total of 6 days, 2 hours, 3 minutes, and 51 seconds. STS-61-C was the last successful Space Shuttle flight before the Challenger disaster, which occurred on January 28, 1986, only 10 days after Columbia ' s return. Accordingly, commander Gibson later called the STS-61-C mission "The End of Innocence" for the Shuttle Program ...
STS-61-A (also known as Spacelab D-1) was the 22nd mission of NASA's Space Shuttle program. It was a scientific Spacelab mission, funded and directed by West Germany – hence the non-NASA designation of D-1 (for Deutschland-1). STS-61-A was the ninth and last successful flight of Space Shuttle Challenger before the disaster.
After the Challenger disaster, the flight was remanifested as STS-35 and several crew members were replaced. Both Richards and Leestma were reassigned to STS-28 while McBride left NASA in 1989. Vance D. Brand replaced McBride as the commander while Guy S. Gardner and John M. Lounge replaced Richards and Leestma, respectively.
The mission restored the spaceborne observatory's vision (marred by spherical aberration in its mirror) with the installation of a new main camera and a corrective optics package (COSTAR). This correction occurred more than three and a half years after the Hubble was launched aboard STS-31 in April 1990.
Thus, neither the British nor the Indonesian payload specialists got a second chance for a spaceflight. The NASA crew however stayed together and participated in a 56-hour-long simulated mission known as STS-61-M(T) in 1987. The crew finally flew on STS-29, with Anna L. Fisher being replaced by James P. Bagian.
