Distances to different orbits can be hard to understand. For example, the ISS sits around 400 kilometers from Earth, whereas some satellites, such as Starlink, orbit at about 550 km. Often that is intentional, as objects...

On Dec. 2, the world will finally get a glimpse at the B-21 Raider, a new stealth bomber that has been described as "the most advanced military aircraft ever built."

Exotrail, a French company developing orbital transfer vehicles, has signed a contract with German launch vehicle developer Isar Aerospace for multiple launches over the next several years. The post Exotrail signs launch...

There are several theories about how Earth and its moon were formed, most involving a giant impact. Now scientists at the University of Leeds and the University of Chicago have analyzed the dynamics of fluids and electri...

Getting to space has almost always been a multi-stage process. Those stages typically took the form of different stages of chemical rockets, but it doesn’t have to be that way. Plenty of alternative options have been p...
