The rocket has already flown in space with a NASA satellite two months ago and now it is destined to leave the planet again.
This time, there is a special unit of cargo on board — Crew Interactive Mobile Companion (CIMON) — an AI robot 'crew member', which looks like a volleyball with a computer screen, displaying its cartoon face. The robot will be used by the astronauts at the ISS and will help them in a few experiments on board.
