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.
The launch complex for liquid fueled rockets often has extensive ground support equipment including propellant tanks and plumbing to fill the rocket before launch. Cryogenic propellants ( liquid oxygen oxidizer, and liquid hydrogen or liquid methane fuel) need to be continuously topped off (i.e., boil-off replaced) during the launch sequence ...
It showcased the use of a multi-stage rocket, and also pioneered the concept of a rocket launch pad (a rocket standing upright against a tall building before launch having been slowly rolled into place) and the rocket-launch countdown clock. [23] [24] The Guardian film critic Stephen Armstrong states Lang "created the rocket industry". [23]
In the context of a rocket launch, the "L minus Time" is the physical time before launch, e.g. "L minus 3 minutes and 40 seconds". "T minus Time" is a system to mark points at which actions necessary for the launch are planned - this time stops and starts as various hold points are entered, and so doesn't show the actual time to launch.
Usage of rockets as weapons before modern rocketry is attested to in China, Korea, India, and Europe. One of the first recorded rocket launchers is the "wasp nest" fire arrow launcher produced by the Ming dynasty in 1380. In Europe, rockets were also used in the same year at the Battle of Chioggia.
A Blue Origin New Shepard rocket lifts off from the company's launch site in West Texas on March 31, 2022. The mission carried five paying passengers and Gary Lai, New Shepard's chief architect ...
1957 - Launch of the first ICBM, the USSR's R-7 (8K71), known to NATO as the SS-6 Sapwood. 1957 - The USSR launches Sputnik 1, the first artificial satellite. 1958 - The U.S. launches Explorer 1, the first American artificial satellite, on a Jupiter-C rocket. 1958 - US launches their first ICBM, the Atlas-B (the Atlas-A was a test article only).
The incident highlights the growing issue of tensions between rocket launches and commercial aviation. SpaceX had to abandon a rocket launch 11 seconds before liftoff over fears a plane flew into ...
