#launch abort

[lonestarflight]

Space Shuttle Discovery was scheduled to lift off at 8:43 a.m. on STS-41-D, waits on the launch pad for the countdown to resume. The ignition sequence was halted at T -4 seconds by onboard computers when the No. 3 engine failed to achieve internal ignition. This caused Discovery to be returned to Orbiter Precessing Facility for an engine replacement and this delayed her maiden flight for over two months.

Crew Safe After Soyuz Launch Abort

NASA astronaut Nick Hague and Russian cosmonaut Alexey Ovchinin are in good condition following an aborted launch of their Soyuz spacecraft.

The Soyuz MS-10 spacecraft launched from the Baikonur Cosmodrome in Kazakhstan to the International Space Station at 4:40 a.m. EDT Thursday, October 11 (2:40 p.m. in Baikonur) carrying American astronaut Nick Hague and Russian cosmonaut Alexey Ovchinin. Shortly after launch, there was an anomaly with the booster and the launch ascent was aborted, resulting in a ballistic landing of the spacecraft. Search and rescue teams were deployed to the landing site. Hague and Ovchinin are out of the capsule and are reported to be in good condition.

Note: This video is edited for length, but includes the launch, the initial report of the issue, and the confirmation that the crew landed safely.

Launch attempt of STS-55

"STS-55 Columbia, Orbiter Vehicle (OV-102), SSME abort at KSC LC Pad 39A

The second Space Shuttle launch attempt of 1993 comes to an abrupt halt when one of the three main engines on the orbiter Columbia shuts down at T -3 seconds, resulting in an on-the-pad abort of Mission STS-55. This was the first time in the post-Challenger era that a main engine shutdown has halted a Shuttle launch countdown, and only the third time in the history of the program. In 1984, STS-41-D was scrubbed at T -4 seconds when the orbiter General Purpose Computer detected an anomaly in a main engine, and in 1985, STS-51-F was halted at T -3 seconds due to a main engine malfunction that caused shutdown of all three engines. On Launch Pad 39B is the Space Shuttle Discovery, undergoing preparations for lift off on Mission STS-56.'

Some launch abort testing from a year ago or so... (btw. I have two followers now, which means I’m finally not posting to myself anymore!) Thank you! :D
