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 .

2023年4月17日 · Designing and testing chemical propulsion systems and nuclear thermal engines for satellites and spacecraft, in support of NASA’s space exploration missions.

2025年1月24日 · Space Nuclear Propulsion (SNP) is one technology that can provide high thrust and double the propellant efficiency of chemical rockets, making it a viable option for crewed missions to Mars.

4 天之前 · Space mission and science news, images and videos from NASA's Jet Propulsion Laboratory, the leading center for robotic exploration of the solar system.

2025年1月23日 · Space Propulsion. We focus on research and technology for flight demonstration components and systems for spacecraft propulsion systems, propulsion stages, and cryogenic fluid flight systems. Our research and technology development enables new space exploration capabilities as well as increased reliability, safety, and affordability.

During the Artemis I uncrewed test flight, a single liquid hydrogen and liquid oxygen-fed RL10B-2 engine producing 24,750 pounds (110kN) of thrust will serve as the main propulsion for the Interim Cryogenic Propulsion Stage that will send the Orion spacecraft to the Moon. Learn More

2025年2月11日 · Chemical in-space propulsion systems, used in orbital systems such as satellites, space tugs, and space probes, generally do not have high acceleration requirements like launch vehicles. For orbital change manoeuvrers of satellites and cargo modules, thrust levels are considerably lower, typically ranging from 10 N to 1000 N, with re ...

2022年4月19日 · In collaboration with U.S. industry, SSEP has developed a lightweight thruster capable of propelling a small spacecraft from Earth to the Moon, Mars, and beyond – a step up from most existing low-power electric propulsion systems produced commercially for low-Earth orbit operations.

5 天之前 · NASA’s Jet Propulsion Laboratory in Southern California manages Lunar Trailblazer and provides system engineering, mission assurance, the HVM3 instrument, and mission design and navigation. Lockheed Martin Space provides the spacecraft, integrates the flight system, and supports operations under contract with Caltech.

6 天之前 · In the search for these frozen compounds, the mission will focus on molecular clouds — collections of gas and dust in space — like this one imaged by the agency’s James Webb Space Telescope. ...
