Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry.
A pulsed inductive thruster (PIT) is a form of ion thruster, used in spacecraft propulsion. It is a plasma propulsion engine using perpendicular electric and magnetic fields to accelerate a propellant with no electrode.
A reaction wheel (RW) is an electric motor attached to a flywheel, which, when its rotation speed is changed, causes a counter-rotation proportionately through conservation of angular momentum. A reaction wheel can rotate only around its center of mass; it is not capable of moving from one place to another.
Aerobraking is a spaceflight maneuver that reduces the high point of an elliptical orbit (apoapsis) by flying the vehicle through the atmosphere at the low point of the orbit (periapsis). The resulting drag slows the spacecraft. Aerobraking is used when a spacecraft requires a low orbit after arriving at a body with an atmosphere, as it requires less fuel than using propulsion to slow down.
Laser propulsion is a form of beam-powered propulsion where the energy source is a remote laser system and separate from the reaction mass. This form of propulsion differs from a conventional chemical rocket where both energy and reaction mass come from the solid or liquid propellants carried on board the vehicle.
Aerocapture is an orbital transfer maneuver in which a spacecraft uses aerodynamic drag force from a single pass through a planetary atmosphere to decelerate and achieve orbit insertion.
A Mars sample-return (MSR) mission is a proposed mission to collect rock and dust samples on Mars and return them to Earth. Such a mission would allow more extensive analysis than that allowed by onboard sensors.
Spacecraft electric propulsion is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generating thrust to modify the velocity of a spacecraft in orbit. The propulsion system is controlled by power electronics.
Gregory Errol Chamitoff is a Canadian-born American engineer and former NASA astronaut. He has been to space twice, spending 6 months aboard the ISS across Expedition 17 and 18 in 2008, and another 15 days as part of STS-134 in 2011. STS-134 was the last of Space Shuttle Endeavour which delivered the Alpha Magnetic Spectrometer and completed the US Orbital Segment.
The idea of sending humans to Mars has been the subject of aerospace engineering and scientific studies since the late 1940s as part of the broader exploration of Mars. Long-term proposals have included sending settlers and terraforming the planet. Currently, only robotic landers and rovers have been on Mars. The farthest humans have been beyond Earth is the Moon, under the U.S. National Aeronautics and Space Administration (NASA) Apollo program which ended in 1972.
An orbital propellant depot is a cache of propellant that is placed in orbit around Earth or another body to allow spacecraft or the transfer stage of the spacecraft to be fueled in space. It is one of the types of space resource depots that have been proposed for enabling infrastructure-based space exploration. Many depot concepts exist depending on the type of fuel to be supplied, location, or type of depot which may also include a propellant tanker that delivers a single load to a spacecraft at a specified orbital location and then departs. In-space fuel depots are not necessarily located near or at a space station.
Safe mode is an operating mode of a modern uncrewed spacecraft during which all non-essential systems are shut down and only essential functions such as thermal management, radio reception and attitude control are active.
Robert David Braun is an American aerospace engineer and academic. He has served as the dean of the College of Engineering and Applied Science at the University of Colorado Boulder, the David and Andrew Lewis Professor of Space Technology at the Georgia Institute of Technology, and the NASA Chief Technologist. Currently, Dr. Braun is the Space Sector Head at the Johns Hopkins University Applied Physics Laboratory (APL).
Electra, formally called the Electra Proximity Link Payload, is a telecommunications package that acts as a communications relay and navigation aid for Mars spacecraft and rovers. The use of such a relay increases the amount of data that can be returned by two to three orders of magnitude.
The Asteroid Redirect Mission (ARM), also known as the Asteroid Retrieval and Utilization (ARU) mission and the Asteroid Initiative, was a space mission proposed by NASA in 2013; the mission was later cancelled. The Asteroid Retrieval Robotic Mission (ARRM) spacecraft would rendezvous with a large near-Earth asteroid and use robotic arms with anchoring grippers to retrieve a 4-meter boulder from the asteroid.
Powtawche N. Valerino is an American mechanical engineer at the NASA Jet Propulsion Laboratory. She worked as a navigation engineer for the Cassini mission.
Moriba Kemessia Jah CorrFRSE is an American space scientist and aerospace engineer who describes himself as a "space environmentalist". He specializes in orbit determination and prediction, especially as related to space situational awareness and space traffic monitoring. He is currently a full professor of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin, a position he attained in 2024, and a National Geographic Explorer. Jah has co-founded Privateer Space x Orbital Insight, GaiaVerse, and Moriba Jah Universal. His work now broadly focuses on decision intelligence to improve the stewardship of the planet and beyond.
The Power and Propulsion Element (PPE), previously known as the Asteroid Redirect Vehicle propulsion system, is a planned solar electric ion propulsion module being developed by Maxar Technologies for NASA. It is one of the major components of the Lunar Gateway. The PPE will allow access to the entire lunar surface and a wide range of lunar orbits and double as a space tug for visiting craft.
Swati Mohan is an Indian-American aerospace engineer and was the Guidance and Controls Operations Lead on the NASA Mars 2020 mission.
