STS-41-C post flight presentation, narrated by the astronauts (19 minutes). STS-41-C launched successfully at 8:58 a.m. EST on April 6, 1984. The mission marked the first direct ascent trajectory for the Space Shuttle; Challenger reached its 533 km (331 mi) - high orbit using its Orbiter Maneuvering System (OMS) engines only once, to ...
After 5.7 years its orbit had decayed to about 175 nautical miles (324 km) and it was likely to burn up on reentry in a little over a month. [6] [9]: 15 It was finally recovered by Columbia on mission STS-32 on January 12, 1990. [19] Columbia approached LDEF in such a way as to minimize possible contamination to LDEF from thruster exhaust. [20]
STS-41 launches from Kennedy Space Center, on October 6, 1990. Ulysses after deployment. Discovery lifted off on October 6 1990 at 7:47:16 a.m. EDT. Liftoff occurred 12 minutes after a two-and-a-half-hour launch window opened that day at 7:35 a.m. EDT. STS-41 featured the heaviest payload to date; Discovery weighed 117,749 kg (259,592 lb). [2]
It was first tested on February 7 during mission STS-41-B by astronauts Bruce McCandless II and Robert L. Stewart. Two months later, during mission STS-41-C , astronauts James van Hoften and George Nelson attempted to use the MMU to capture the Solar Maximum Mission satellite and to bring it into the orbiter's payload bay for repairs and servicing.
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 ...
ERBS was launched on October 5, 1984, by the Space Shuttle Challenger during the STS-41-G mission and deactivated on October 14, 2005. [4] It re-entered the Earth's atmosphere on January 8, 2023, over the Bering Sea near the Aleutian Islands. [5] [6] NASA's CERES instruments have continued the ERB data record after 1997.

The Neutral Buoyancy Simulator was a neutral buoyancy pool located at NASA's George C. Marshall Space Flight Center (MSFC). Engineers and astronauts developed hardware and practiced procedures in this tank from its completion in 1968 through its decommissioning in 1997.
