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 ...
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 ...
This was the first and only time it was ever activated in a NASA-controlled human space-launch. In rocketry, range safety or flight safety is ensured by monitoring the flight paths of missiles and launch vehicles, and enforcing strict guidelines for rocket construction and ground-based operations. Various measures are implemented to protect ...
For rocket-like propulsion systems, this is a function of mass fraction and exhaust velocity; mass fraction for rocket-like systems is usually limited by propulsion system weight and tankage weight. [ citation needed ] For a system to achieve this limit, the payload may need to be a negligible percentage of the vehicle, and so the practical ...
It is jointly organized by NASA and the global education company I Doodle Learning, with the objective of teaching school students aged 11–18 to design and build scientific experiments to be launched into space on a NASA rocket or balloon. On June 21, 2017, the world's smallest satellite, KalamSAT, was launched.
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"
A NASA history from 1998 says that reusable single-stage-to-orbit (SSTO) rockets and space planes such as the McDonnell Douglas DC-X and the Lockheed Martin X-33 seemed attainable and represented smaller, simpler alternatives to the sprawling Shuttle program. [8] The NLS, by contrast, was more of a continuation of the Shuttle legacy.
NASA uses a certification system for rockets launched by its contractors, and for validation purposes it requires the certification process to be "instrumented to provide design verification and flight performance data", with post-flight operations, anomaly resolution process, and a flight margin verification process, with 80% predicted design ...
