A reboost of the International Space Station was completed at 5:04 a.m. EDT Wednesday as the engines of the docked ISS Progress 39 cargo craft fired for eight minutes, 46 seconds to raise the perigee of the station’s orbit by about three statute miles.

The reboost set up the correct phasing of the station for the Soyuz TMA-18 spacecraft‘s undocking on Sept. 23. It will return to Earth that same night with Expedition 24 Commander Alexander Skvortsov and Flight Engineers Tracy Caldwell Dyson and Mikhail Kornienko aboard. The trio’s departure will signal the start of Expedition 25 under the command of current Flight Engineer Doug Wheelock.

Aboard the station, Caldwell Dyson and Wheelock participated in an in-flight interview with The Weather Channel, discussing their view of Hurricanes Igor and Julia from space. The crew continues to photograph the storms as part of ongoing Earth observation from the station.

Flight Engineer Fyodor Yurchikhin photographed and documented developments and conditions in the Earth’s oceans as part of the ongoing Russian Seiner experiment, which provides scientists on the ground with current position coordinates of bioproductive water areas in the Earth’s oceans.

Yurchikhin also set up and used video and photography equipment in support of the Russian Uragan experiment. Uragan, the Russian word for hurricane, is a long-term experiment that documents the changes that occur on Earth after catastrophes such as hurricanes and man-made disasters.

Caldwell Dyson and Wheelock worked with the Kids in Micro-g! student experiments. The Kids in Micro-g! experiments were designed by students in grades 5-8 as part of a national contest. The experiments will be recorded in high definition video and the winners supplied with copies of their video before the end of their school year.

Meanwhile, Flight Engineer Shannon Walker checked the station’s water quality as she took water samples from the Potable Water Dispenser and the water supply in the Zvezda service module then tested them using the Total Organic Carbon Analyzer.
