Progress Spacecraft undocking from the ISS during Expedition 16

ISS016-E-035177 (7 April 2008) --- An unpiloted Progress 28 resupply vehicle departs from the Pirs Docking Compartment of the International Space Station at 4:50 a.m. (EDT) on Monday, April 7, 2008, and headed into its deorbit and destructive re-entry into Earth's atmosphere over the Pacific Ocean. The Progress, which has been attached to the station since February, had been loaded with trash and discards before its departure. The undocking clears the way for the arrival Thursday of the Soyuz TMA-12 spacecraft carrying the Expedition 17 crew and a South Korean spaceflight participant.
