These Tiny Satellites Just Left The International Space Station

These Tiny Satellites Just Left The International Space Station


A pair of nanosatellites were deployed by the NanoRacks Launcher on the end of the Japanese robotic arm of the International Space Station on Friday. The tiny CubeSats are loaded with tools to observe the planet and conduct other scientific experiments.

CubeSats are NASA's nanosatellite program for lightweight, self-contained experiments that can fly as small auxiliary payloads on planned launches. A few are tucked into most cargo runs to the space station, an added bonus of science to the regular payload.

The cube-shaped satellites are about 10 centimetres long, weighing under 1.5 kilograms. Lacking in sophisticated orbital stabilizing equipment, the CubeSats are in decaying orbits and typically only remain in space for a few months to years before burning up in the atmosphere.

Last time we checked in on the CubeSats, the NanoRack Launcher was spontaneously launching them from the space station without astronaut intervention. The root cause of the malfunction was overly tightened dispenser screws. Since it was replaced, it has been functioning normally, only releasing satellites at the request of its controlling astronauts.
