The International Space Station fired its engines Wednesday night slightly raising its orbit to accommodate a crew exchange in April. In the meantime, the six-person Expedition 50 crew continued learning how living in space affects the human body.
The station’s third module, the Zvezda service module which launched in 2000, fired its main engines for 43 seconds overnight. The orbital reboost places the station at the correct altitude for the departure of three Expedition 50 crew members April 10. Just ten days later, two new space residents will arrive completing the Expedition 51 crew.
Scientists are exploring the best nutrition requirements to keep astronauts healthy and productive during long-term space missions. Astronaut Thomas Pesquet is contributing to that research today beginning a prescribed diet for the next 11 days. During that period he will collect urine samples and measure his breathing for the Energy study. Results will help researchers plan meals to ensure successful missions farther out into space.
Flight Engineer Peggy Whitson, who will become station commander April 9, peered at stem cells through a specialized microscope on today. She is helping scientists understand how microgravity increases stem cell replication possibly improving disease treatments on Earth.
