Flight dynamics calculations are handled by computerized guidance systems aboard the vehicle; the status of the flight dynamics is monitored on the ground during powered maneuvers by a member of the flight controller team known in NASA's Human Spaceflight Center as the flight dynamics officer, or in the European Space Agency as the spacecraft ...
The flight dynamics of spacecraft differ from those of aircraft in that the aerodynamic forces are of very small, or vanishingly small effect for most of the vehicle's flight, and cannot be used for attitude control during that time. Also, most of a spacecraft's flight time is usually unpowered, leaving gravity as the dominant force.
A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. It is often needed so that the spacecraft high-gain antenna may be accurately pointed to Earth for communications, so that onboard experiments may accomplish precise pointing for accurate collection and subsequent interpretation of data, so that the heating and cooling effects of sunlight and shadow ...
Neil B. Hutchinson, Silver Flight. Apollo missions 16, 17 and Apollo-Soyuz. [2] Flight activities officer (FAO) The FAO planned and supported crew activities, checklists, procedures and schedules. Flight dynamics officer (FDO or FIDO) Responsible for the flight path of the space vehicle, both atmospheric and orbital.
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 company said it will need to analyze post-flight data to determine if those objectives were completed. SpaceX also intended to fire one of Starship’s Raptor engines while in space, but it ...
TDRS Program Logo Location of TDRS as of March 2019 An unflown TDRS on display at the Steven F. Udvar-Hazy Center in Chantilly, Virginia.. The U.S. Tracking and Data Relay Satellite System (TDRSS, pronounced "T-driss") is a network of American communications satellites (each called a tracking and data relay satellite, TDRS) and ground stations used by NASA for space communications.
The spacecraft would approach Mars on a hyperbolic orbit, and a final retrograde burn would slow the spacecraft enough to be captured by Mars. Friedrich Zander was one of the first to apply the patched-conics approach for astrodynamics purposes, when proposing the use of intermediary bodies' gravity for interplanetary travels, in what is known ...
