A launch status check, also known as a "go/no go poll" and several other terms, occurs at the beginning of an American spaceflight mission in which flight controllers monitoring various systems are queried for operation and readiness status before a launch can proceed. For Space Shuttle missions, in the firing room at the Launch Control Center ...
The improvement of expendable launch vehicles and the transition away from commercial payloads on the Space Shuttle resulted in expendable launch vehicles becoming the primary deployment option for satellites. [28]: III–109–112 A key customer for the Space Shuttle was the National Reconnaissance Office (NRO) responsible for spy satellites ...
The longest orbital flight of the Shuttle was STS-80 at 17 days 15 hours, while the shortest flight was STS-51-L at one minute 13 seconds when the Space Shuttle Challenger broke apart during launch. The cold morning shrunk an O-Ring on the right Solid Rocket Booster causing the external fuel tank to explode.
"Due to unfavorable weather forecasted in Dragon's splashdown areas off the coast of Florida, we are now standing down from tonight and tomorrow's Falcon 9 launch opportunities of Polaris Dawn ...
The launch will use the company’s Falcon 9 rocket; the first-stage booster that will be used previously launched the NROL-87, NROL-85 and SARah-1 missions, SpaceX said.
The positioning had to be precise. The shuttle's nose was raised 200 feet into the night sky so that the rudder could clear 80 feet of space. Endeavour was then turned 17 degrees clockwise to ...
Launch Complex 39A (LC-39A) is the first of Launch Complex 39's three launch pads, located at NASA's Kennedy Space Center in Merritt Island, Florida.The pad, along with Launch Complex 39B, was first constructed in the 1960s to accommodate the Saturn V launch vehicle, and has been used to support NASA crewed space flight missions, including the historic Apollo 11 moon landing and the Space Shuttle.
[22] [30] In addition, a 2017 study suggested that a single SLS Block 1B launch vehicle could launch two spacecraft, one to each ice giant, with launch dates suggested from 2024 to 2037 followed by a four-year transit time. [31] Updated versions of the proposal recommend using a Falcon Heavy instead of SLS. [32]
