The Progress docked to the aft port of the station's Zvezda Service Module at 1:23 a.m. CDT as the two spacecraft orbited about 240 statute miles above Central Asia. Shortly after first contact, hooks and latches engaged between the Progress and Zvezda to lock the two together.
Expedition 5 crewmembers, Commander Valery Korzun, Astronaut Peggy Whitson and Cosmonaut Sergei Treschev, will do leak checks between the Progress and Zvezda before opening hatches at about 4:30 a.m. to gain access to the newly arrived vehicle. The crew will unload its cargo during the coming days.
Progress 8 replaces the Progress 7 cargo carrier at the space station. Progress 7 was undocked early Tuesday and deorbited later that morning. It burned in the Earth's atmosphere with its load of trash from the ISS.
This week, the crew continued to settle into its new home and conduct scientific experiments. Whitson and Treschev worked to activate the Zeolite Crystal Growth Furnace, and Korzun and Whitson performed their first of several monthly sessions with the Pulmonary Function experiment to test their lung capabilities while living in a microgravity environment. Whitson took the first samples from the Advanced Astroculture soybean plant growth experiment.
