The launch, which took place at Baikonur Cosmodrome on Wednesday afternoon, fired a Proton-M rocket into the sky, carrying the laboratory. Less than ten minutes after takeoff, Proton-M detached from the module, putting it into orbit. It is due to be docked to the Russian section of the ISS on July 29.
Nauka, which will be used for experiments, can also generate oxygen for six people and regenerate water from urine. It will also have a second toilet for Russian cosmonauts and be able accommodate a third crew member.
Attached to the module is a European Robotic Arm (ERA) that can help with installing and replacing station components without the need to perform a spacewalk.
