STS-51L
STS-51-L was the disastrous 25th mission of NASA's Space Shuttle program and the final flight of Space Shuttle ''Challenger''. It was planned as the first Teacher in Space Project flight in addition to observing Halley's Comet for six days and performing a routine satellite deployment. The mission never achieved orbit; a structural failure during its ascent phase 73 seconds after launch from Kennedy Space Center Launch Complex 39B on January 28, 1986, destroyed the orbiter and killed all seven crew members—Commander Francis R. "Dick" Scobee, Pilot Michael J. Smith, Mission Specialists Ellison S. Onizuka, Judith A. Resnik and Ronald E. McNair, and Payload Specialists Gregory B. Jarvis and S. Christa McAuliffe. Immediately after the failure, President Ronald Reagan convened the Rogers Commission to determine the cause of the explosion. The failure of an O-ring seal on the starboard Solid Rocket Booster (SRB) was determined to have caused the shuttle to break up in fl ...

Space Shuttle Challenger Disaster
On January 28, 1986, the Space Shuttle Challenger, Space Shuttle ''Challenger'' broke apart 73 seconds into its flight, killing all seven crew members aboard. The spacecraft disintegrated above the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 16:39:13Coordinated Universal Time, UTC (11:39:13a.m. Eastern Time Zone, EST, local time at the launch site). It was the first fatal accident involving an List of space programs of the United States, American spacecraft while in flight. The mission, designated STS-51-L, was the 10th flight for the Space Shuttle orbiter, orbiter and the 25th flight of the Space Shuttle fleet. The crew was scheduled to deploy a commercial communications satellite and study Halley's Comet while they were in orbit, in addition to taking schoolteacher Christa McAuliffe into space under the Teacher in Space Project. The latter task resulted in a higher-than-usual media interest in and coverage of the mission; the launch and subsequent disaste ...

Halley's Comet
Halley's Comet is the only known List of periodic comets, short-period comet that is consistently visible to the naked eye from Earth, appearing every 72–80 years, though with the majority of recorded apparitions (25 of 30) occurring after 75–77 years. It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061. Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply Halley. Halley's periodic returns to the inner Solar System have been observed and recorded by astronomers around the world since at least 240 BC, but it was not until 1705 that the English astronomer Edmond Halley understood that these appearances were re-appearances of the same comet. As a result of this discovery, the comet is named after Halley. During its 1986 visit to the inner Solar System, Halley's Comet became the first comet to be observed in detail by a spacecraft, ''Giotto (spacecraft), Giotto'', providing the first obser ...

Space Shuttle Challenger
Space Shuttle ''Challenger'' (OV-099) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after HMS Challenger (1858), the commanding ship of a Challenger expedition, nineteenth-century scientific expedition that traveled the world, ''Challenger'' was the second Space Shuttle orbiter to fly into space after ''Space Shuttle Columbia, Columbia'', and launched on STS-6, its maiden flight in April 1983. It was destroyed in January 1986 soon after launch Space Shuttle Challenger disaster, in a disaster that killed all seven crewmembers aboard. Initially manufactured as a Test article (aerospace), test article not intended for spaceflight, it was used for ground testing of the Space Shuttle orbiter's structural design. However, after NASA found that their original plan to upgrade ''Space Shuttle Enterprise, Enterprise'' for spaceflight would be more expensive than upgrading ''Challenger'', the orbiter was pressed into operational service in ...

Space Shuttle Solid Rocket Booster
The Space Shuttle Solid Rocket Booster (SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. A pair of them provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent. After burnout, they were jettisoned, and parachuted into the Atlantic Ocean, where they were recoverable booster, recovered, examined, refurbished, and reusable launch system, reused. The Space Shuttle SRBs were the most powerful solid rocket motors to ever launch humans. The Space Launch System (SLS) SRBs, adapted from the shuttle, surpassed it as the most powerful solid rocket motors ever flown, after the launch of the Artemis 1 mission in 2022. Each Space Shuttle SRB provided a maximum thrust, roughly double the most powerful single-combustion chamber liquid-propellant rocket engine ever flown, the Rocketdyne F-1. With a combined mass of about , they comprised over half the mass of the Shuttle stack at liftoff. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
