The Progress M1-2 unmanned cargo spacecraft was launched successfully this evening (April 25) from Baikonur Cosmodrome, and is heading for a Thursday, April 27 docking with Mir.
"We are delighted that MirCorp has once again met its technical milestone," MirCorp President Jeffrey Manber said. "With today's launch and last week's repair of the small air leak on Mir, we are well underway with the renovation of our first home in space."
Under terms of the historic Mir commercial lease agreement signed in February, today's Progress M1-2 launch was a MirCorp and RSC Energia-funded mission. "There were no funds provided from any government for the launch of Progress M1-2 to Mir," Manber said. "This is a truly commercial flight."
Progress M1-2 will arrive at the station's rear docking port, located on the Kvant-1 module. It will replace the Progress M1-1 cargo re-supply craft, which has been docked to Mir since early April.
The Progress spacecraft are used to ferry supplies, equipment and other material to the Russian space station. They also carry air and propellant for Mir, and the Progress' own engines/thrusters often are used for burns to change or correct the space station's orbit.
On Mir, the docking interface fasteners with Progress M1-1 were disassembled this afternoon, and cosmonauts Sergei Zalyotin and Alexander Kalery closed the transfer hatches between the spacecraft and Mir's Kvant module. The Progress M1-1 is scheduled to undock from Mir tomorrow at 16h30 GMT, with the arrival of Progress M1-2 planned on Thursday at 21h30 GMT to take its place.
Progress M1-1 will be commanded to make a controlled destructive reentry in the Earth's atmosphere after a job well done in support of Mir's historic reactivation for MirCorp.
