Summary
Progress M-27M launched on a Russian Federal Space Agency (ROSCOSMOS) Soyuz 2.1a from 31/6, Baikonur Cosmodrome, Republic of Kazakhstan on April 28, 2015. The mission failed: After reaching low Earth orbit, but before separation of the spacecraft from the rocket, communication with the vessel was lost. Ground controllers only received brief telemetry shortly after that confirmed spacecraft separation as well as the deployment of the solar panels, but were not able to confirm the deployment of rendezvous antennas of the KURS system. Initially controllers tried to fall back to the plan of making a 2-day rendezvous with the ISS, but this was also abandoned after ground stations were not able to communicate with the spacecraft during the next 3 orbits. It was Russian Federal Space Agency (ROSCOSMOS)'s 245th launch, 3rd this year and humanity's 5,467th orbital launch attempt. It was the 7th Soyuz 2.1a flight and the 2nd this year. The payload was bound for low Earth orbit (LEO). The spacecraft was Progress M-27M (Progress M-27M (No.426)). 22 objects from this launch are catalogued, one of them a payload.
