Progress is an expendable-unmanned spacecraft developed by Soviet scientists and currently serving as cargo deliverer to the International Space Station (ISS).
Sputnik brings you a live broadcast from the Baikonur Cosmodrome in Kazakhstan, where Russia is launching its robotic Progress 84 cargo ship to the Internation Space Station (ISS) on Wednesday, May 24.
The journey will take almost three and a half hours. Progress is scheduled to autonomously dock to the Poisk module of the ISS to deliver supplies to cosmonauts, including roughly 2.5 tonnes of food and water. Also, the spacecraft will bring various scientific gear, including the technology needed to launch a mini-satellite with a solar sail, developed by Russian scientists.
Progress, which first came into operation in 1978, is one of three unmanned spacecraft that delivers supplies to the ISS along with the Dragon capsule developed by SpaceX and Cygnus by Northrop Grumman.
