The BlueWalker 3 satellite was fully deployed, making it the "largest-ever commercial communications array in low Earth orbit," at 693 square feet, according to AST SpaceMobile. Credit: AST SpaceMobile | edited by Space.

Astronomers have detected an Earth-size planet candidate orbiting a nearby star once a year, making it a promising target for future studies.

On March 16, 1966, command pilot Neil Armstrong and pilot David Scott successfully docked their Gemini VIII spacecraft with the Agena target vehicle, the first-ever linking of two spacecraft together in Earth orbit.

A seemingly small planetary neighbor may play a larger role in Earth’s climate than previously thought. Mars is only about half the size of Earth and has roughly one tenth of its mass, making it relatively small compared with many planets.

The EDA has awarded a €15.65M contract to a consortium led by Spanish engineering firm Sener to develop the first very low Earth orbit (VLEO) satellite.

NASA's DART mission didn’t just change the orbit of Dimorphos, the asteroid it hit. It changed the orbit of the larger Didymos around the sun.

The rapid expansion of artificial intelligence and cloud services has led to a massive demand for computing power. The surge has strained data infrastructure, which requires lots of electricity to operate. A single, medium-sized data center here on Earth ...

A rock and a hard place

NASA’s DART mission changed the Dimorphos' asteroid orbit around the Sun, proving spacecraft impacts could help defend Earth.
