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 ...
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.
STS-41 was the 36th Space Shuttle mission and the eleventh mission of the Space Shuttle Discovery. The four-day mission had a primary objective of launching the Ulysses probe as part of the " International Solar Polar Mission " (ISPM).
This control system carried out the usual attitude control along the pitch, roll, and yaw axes during all of the flight phases of launching, orbiting, and re-entry. This system also executed any needed orbital maneuvers, including all changes in the orbit's altitude, orbital plane , and eccentricity .
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 ...
He served as Lead Data Processing Systems (DPS) Officer for STS-9 (Spacelab-1) and STS-41-D, Orbit DPS for STS-41-B and STS-41-C, and Ascent/Entry DPS for STS-41-G. He also served as a senior flight controller addressing issues requiring real-time resolution, for several flights from STS-51-A through STS-51-L. [ 3 ]
It had been launched by the STS-41-C mission on April 7, 1984, and by January 1990 its orbit had decayed to about 175 nautical miles (324 km) and it was only a month or so away from re-entering the atmosphere and burning up. [23] The STS-32 mission lifted off from the KSC in the Space Shuttle Columbia on January 9, 1990. [24]
An orbit near the craft's planned orbit was established, and the mission continued despite the abort to a lower orbit. [7] [8] The Mission Control Center at Johnson Space Center observed an SSME failure and called "Challenger-Houston, abort ATO." The engine failure was later determined to be an inadvertent engine shutdown caused by faulty ...
