This remarkable finding breaks the previous record for the shortest outer orbital period in such systems, which was established in 1956 with a third star orbiting an inner pair in 33 days.

lives and conduct "collision avoidance manuevers" to avert orbital smash-ups. It is an incredible honor, Bennett says, for Starfish’s vanguard engineers to have been appointed to spearhead NASA ...

NASA aims to travel to the moon again—and beyond. Here’s a look at the 21st-century race to send humans into space. Private spaceflight is not a new concept. In the United States, commercial ...

This is the future that Reflect Orbital imagines is possible. The startup is developing satellites that would deploy large mirrors to precisely reflect sunlight onto specific points on the ground.

Reflect Orbital plans to deploy 57 small satellites into low-Earth orbit. Each satellite will be outfitted with a 33-square-foot reflective Mylar mirror. These mirrors are designed to reflect ...

Argo Space Corporation aims to contribute to both these capabilities with a reusable orbital transfer vehicle that can be refueled with water harvested from the moon. (Oh, and Argo Space wants to ...
