Elon Musk has an armada of Starlink communications satellites. Here's how Beijing is thinking about countering them.

NASA's ion thrusters work through what is known as the Hall effect. Rather than use a chemical process to create propulsion, Hall-effecct ion thrusters use an electric field from solar panels to ...

Due to atmospheric drag, even the ISS experiences gradual deceleration over time. This friction with the thin traces of Earth ...

Having fuel-efficient thrusters will help with this. Eventually, toward the end of this 21-month period, the spacecraft will come to within about 100 km of the surface of Psyche, which has a ...

Voyager 1, launched in September 1977, uses more than one set of thrusters to function properly. Primary thrusters carefully orient the spacecraft so it can keep its antenna pointed at Earth.

Michigan-based startup Orbion has secured $9.2 million in Series A funding, which it will use as it undertakes the mass-produced manufacturing of its plasma thrusters for use in small satellites.

After nearly a year of trying to fix the ill-fated spacecraft, NASA says Starliner is set for a cargo mission in 2026.
