Astra never sought to build the best rocket, the biggest rocket, or the safest rocket. The California-based space company simply wanted to build a rocket that was just good enough, and to do it fast.
Early on Saturday morning, Astra proved the value of this philosophy by successfully launching a stripped-down rocket for the first time. The mission hefted a small test payload for the US Space Force into an orbit 500 km above the planet.
The launch came five years and one month after Astra was founded by Chris Kemp and Adam London in October 2016.

Firefly, Virgin Orbit, and Rocket Lab all needed seven or more years to successfully reach orbit.
