The plane was permanently retired in 1998, and the Air Force quickly disposed of their SR-71s, leaving NASA with the last two airworthy Blackbirds until 1999. [36] All other Blackbirds have been moved to museums except for the two SR-71s and a few D-21 drones retained by the NASA Armstrong Flight Research Center. [37] Lockheed U-2 "Dragon Lady"
The middle rocket shows the straight-line flight configuration in which the direction of thrust is along the center line of the rocket and through the center of gravity of the rocket. On the rocket at the left, the nozzle has been deflected to the left and the thrust line is now inclined to the rocket center line at an angle called the gimbal ...

Once in orbit, a spacecraft may fire rocket engines to make in-plane changes to a different altitude or type of orbit, or to change its orbital plane. These maneuvers require changes in the craft's velocity, and the classical rocket equation is used to calculate the propellant requirements for a given delta-v .
For Space Shuttle missions, in the firing room at the Launch Control Center, the NASA Test Director (NTD) performed this check via a voice communications link with other NASA personnel. The NTD was the leader of the shuttle test team responsible for directing and integrating all flight crew, orbiter, external tank/solid rocket booster and ...
The U.S. Air Force also participated in the program, but different requirements led to some divergence in the development of NASA and USAF Scouts. The basic NASA Scout configuration, from which all variants were derived, was known as Scout-X1. It was a four-stage rocket, which used the following motors: 1st stage: Aerojet General Algol
The Aerial Regional-scale Environmental Survey (ARES) was a proposal by NASA's Langley Research Center to build a robotic, rocket-powered airplane that would fly one mile above the surface of Mars, [1] in order to investigate the atmosphere, surface, and sub-surface of the planet.
NASA's Space Launch System is planned to use an AFTS by the flight of Artemis 3. [64] In 2020 NASA started developing the NASA Autonomous Flight Termination Unit (NAFTU) for use on commercial and government launch vehicles. Provisional certification of the unit was granted in 2022 for Rocket Lab's first U.S. Electron mission (from Wallops ...
