A thruster is a spacecraft propulsion device used for orbital station-keeping, attitude control, or long-duration, low-thrust acceleration, ...
A pair of translation thrusters are located at the rear of the Soyuz spacecraft; the counter-acting thrusters are similarly paired in the middle of the spacecraft (near the center of mass) pointing outwards and forward. These act in pairs to prevent the spacecraft from rotating.
The eight rotational control engines were mounted off the spacecraft's center of mass around the aft section of the Equipment Module, pointed at 90 degree positions up, down, left and right. These were rated at 25 pounds-force (110 N) thrust and fired in pairs, causing it to yaw, pitch, or roll to control attitude.
Engineers at NASA have successfully fired up a set of thrusters Voyager 1 hasn’t used in decades to solve an issue that could keep the 47-year-old spacecraft from communicating with Earth from ...
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 ...
The LACE satellite, Space Shuttle, and ground station during an observation attempt. Several attempts were made between 1990 and 1992 to image the plumes fired by the Space Shuttle from its Orbital Maneuvering System pods and Reaction Control System thrusters as it orbited in low-earth orbit at a lower orbital inclination than LACE. The UVPI ...
The breakthrough could mean deep space exploration is no longer the stuff of sci-fi, according to University of Southampton engineers. New rocket thruster could mean humans boldly go on never ...
When in space, the purpose of a propulsion system is to change the velocity, or v, of a spacecraft. [7] In-space propulsion begins where the upper stage of the launch vehicle leaves off, performing the functions of primary propulsion, reaction control, station keeping, precision pointing, and orbital maneuvering.
