Space travel has always hit a wall with slow speeds and massive fuel needs. Gravitic propulsion systems offer a game-changing ...

Spacecraft propulsion is used to change the velocity of spacecraft and artificial satellites, or in short, to provide delta-v. There are many different methods. Each method has drawbacks and ...

A U.K.-based space propulsion startup has unveiled an ambitious concept for a nuclear fusion rocket that may dramatically shorten the journey to Mars. In a recent video presentation, Pulsar Fusion ...

Space travel beyond our moon will require a huge shift in space propulsion. That's partly because quicker flights mean crews are exposed to less radiation during the journey.

NASA has committed itself to the study of a number of far-out propulsion methods over the years to advance space exploration. But researchers are hoping the agency's new Propulsion Research Center ...

A startup with a new type of spacecraft propulsion system could make the interplanetary travel seen in “Star Trek” a reality. Magdrive has just closed a £1.4 million seed round led by ...

In-space propulsion systems are the backbone of space exploration, and they’re becoming even more important as companies and government agencies deploy ever-more low-earth orbit (LEO) satellite ...

Other companies are working on nuclear fusion engines for space propulsion, including Pasadena-based Helicity Space, which received investment from aerospace giant Lockheed Martin in 2024.

The burgeoning space industry and the technologies society increasingly relies on—electric grids, aviation and ...

Impulse Space announced Tuesday that it has raised $20 million in seed funding, led by the venture capital firm Founders Fund. The in-space propulsion company, started by noted rocket scientist ...

NASA and the space industry will conduct several missions over the next year to test more efficient, environmentally friendly spacecraft propulsion, including a non-toxic propellant and solar power.

In space, aerobraking can change the orbit of a spacecraft while minimizing the use of its propulsion system and fuel. Spacecraft that orbit around Earth do so in two types of orbits : circular ...
