Rocket Lab's ramp-up is going well so far.

The spaceflight startup launched 13 tiny satellites on its first-ever mission for NASA early this morning (Dec. 16), just a month after acing its first commercial flight.

Fifty-three minutes later, all of the payloads had separated from the Electron's "kick stage" and settled successfully into a circular orbit about 310 miles (500 kilometers) above Earth.

The little satellites will do a variety of work up there. For example, one will measure radiation levels in the Van Allen belts, to help researchers better understand possible effects on spacecraft. Another aims to demonstrate the effectiveness of compact, 3D-printed robotic arms; and yet another will help prove out technology for a new solar-sailing system that could allow small spacecraft to explore deep space, Rocket Lab representatives said. 

California-based Rocket Lab aims to greatly increase access to space using the expendable Electron, which is 57 feet (17 meters) tall and can carry about 500 lbs. (227 kilograms) to Earth orbit on each $5 million mission. (The ELaNa-19 cubesats together weigh about 172 lbs., or 78 kg, Rocket Lab representatives said.)
