[ISS] Final Undocking of Progress M-15M

After a successful redocking on July 29th which allowed testing of a new Kurs NA antenna system onboard the Russian Progress M-15M spacecraft, the vehicle undocked once again for the final time tonight at 21:19 UTC.

The undocking occurred from the Russian Pirs module which opens up the port for the next Russian Cargo spacecraft, Progress M-16M to dock. Progress M-16M will launch from Baikonur on a Russian Soyuz-U booster on August 1st 2012 at 19:35 UTC the craft will then perform a new approach to dock only hours later at 01:24 UTC. If successful future crewed missions may use this approach to negate the need for crew to live in the Soyuz spacecraft for 2 days after Launch.
