The three-member Expedition 24 crew began a new week aboard the International Space Station with reboost activities, science experiments and routine maintenance work Monday.

A four-minute, seven-second firing of the Zvezda service module’s engines Friday night raised the perigee of the station by 9.7 statute miles in the first of three reboost maneuvers to set the complex up at the right altitude for the docking of the Soyuz TMA-19 spacecraft on June 17 and the upcoming docking of the ISS Progress 38 cargo ship. Two more engine firings from the ISS Progress 37 are slated for Monday night to further raise the station’s perigee and complete the reboost maneuvers.

The Soyuz TMA-19 spacecraft is scheduled to launch June 15, carrying Expedition 24 Flight Engineers Doug Wheelock, Fyodor Yurchikhin and Shannon Walker to the orbital outpost.

The new crew members will replace the Expedition 23 crew members who undocked from the orbiting laboratory and landed in Kazakhstan last week. Commander Oleg Kotov and Flight Engineers T.J. Creamer and Soichi Noguchi completed their mission after 163 days in space when they landed in the same Soyuz TMA-17 spacecraft in which they launched.

Commander Alexander Skvortsov inspected filters in the Elektron oxygen generation system.

Flight Engineer Tracy Caldwell Dyson spent time working with the Dietary Intake Can Predict and Protect Against Changes in Bone Metabolism during Spaceflight and Recovery experiment, also known as Pro K. Pro K proposes that a flight diet with a decreased ratio of animal protein to potassium will lead to decreased loss of bone mineral. The experiment will have an impact on the definition of nutritional requirements and development of food systems for future exploration missions.

Flight Engineer Mikhail Kornienko changed out dust collector filters and performed preventive maintenance on the Zvezda module’s ventilation system.

2010 International Space Station Calendar

NASA is offering a 2010 calendar that describes the work being done on the International Space Station and gives information about the crews that have lived there. The calendar contains photographs taken from the space station and highlights historic NASA milestones and fun facts about the international construction project of unprecedented complexity that began in 1998. (Please Note: To print this large calendar on 8.5 by 11 paper, printer may need to be set on a "shrink to printable area" option.)
