An application launcher provides shortcuts to computer programs, and stores the shortcuts in one place so they are easier to find. In the comparison of desktop application launchers that follows, each section is devoted to a different desktop environment .
Apollo Launch Escape System diagram. If the rocket failed in the last five minutes before launch, the CM and the launch escape system (LES, see figure) would separate from the remainder of the rocket below with the LES propelling itself and the CM beneath it upward and eastward to the sea using a small solid-fueled motor (the launch escape motor) at the top of the tower on the launch escape ...
Originally available as a beta since October 2015 [5] under the name Arrow Launcher, the first stable release was published to the Google Play Store, under its current name, on October 5, 2017. [6] It does not replace the stock Android operating system, but adds an additional graphical layer with a focus on Microsoft applications and services.
The Orion spacecraft, which was developed to follow the Space Shuttle program, uses a Mercury and Apollo-style escape rocket system, while an alternative system, called the Max Launch Abort System (MLAS), [4] was investigated and would have used existing solid-rocket motors integrated into the bullet-shaped protective launch shroud.
This crewed flight was to have followed the first three uncrewed flights. After the fire which killed the AS-204 crew on the pad during a test and training exercise, uncrewed Apollo flights resumed to test the Saturn V launch vehicle and the Lunar Module; these were designated Apollo 4, 5 and 6. The first crewed Apollo mission was thus Apollo 7.
Launch operations are supervised and controlled from several control rooms known as firing rooms. The controllers are in control of pre-launch checks, the booster and spacecraft. Once the rocket has cleared the launch tower (usually within the first 10–15 seconds), is when control is switched over to the mission's relative mission control center.
The first three lunar missions (Apollo 8, Apollo 10, and Apollo 11) used a free return trajectory, keeping a flight path coplanar with the lunar orbit, which would allow a return to Earth in case the SM engine failed to make lunar orbit insertion. Landing site lighting conditions on later missions dictated a lunar orbital plane change, which ...
Skylab 2 (also SL-2 and SLM-1 [4]) was the first crewed mission to Skylab, the first American orbital space station.The mission was launched on an Apollo command and service module by a Saturn IB rocket on May 25, 1973, [5] and carried NASA astronauts Pete Conrad, Joseph P. Kerwin, Paul J. Weitz to the station.
