A California-based startup plans to launch hundreds of flattened “microsatellites” into low-Earth orbit at once, by firing rockets out of a giant centrifugal cannon. The first batch of pancake-like spacecraft could be shot into space as soon as next year — and could set a new record. SpinLaunch is a private company that aims to … Read more

This new spaceflight tech has a very retro feel. The world’s first wooden satellite, a tiny Japanese spacecraft called LignoSat, arrived at the International Space Station (ISS) on Tuesday (Nov. 5) aboard a SpaceX Dragon cargo capsule. LignoSat measures just 4 inches (10 centimeters) on each side, but it could end up having a big … Read more

Sitting in the middle of … Read more
In science fiction films, nothing raises tension quite like the good guys’ spaceship getting caught in an invisible tractor beam that allows the baddies to slowly reel them in. But what was once only a sci-fi staple could soon become a reality. Scientists are developing a real-life tractor beam, dubbed an electrostatic tractor. This tractor … Read more
