Space Station Live: Fixing an Ammonia Leak on the Station -- 05.16.13
› Watch video

Brandi Dean interviews SPARTAN flight controller Anthony Vareha. The SPARTAN console in the Mission Control Center is in charge of the station's electrical and thermal systems.

Vareha describes the analysis of the leak of ammonia coolant that cools the batteries on the station's P6 truss, which occurred last week. Expedition 35 Flight Engineers Tom Marshburn and Chris Cassidy conducted a spacewalk May 11 to fix that leak. The planning and readiness for the spacewalk took place in record time.

Flight controllers are still monitoring the system for leaks and will need a couple of months to make their final assessment of the situation.

Space Station Live: Preparing for the Ride Home on a Soyuz Spacecraft – 05.13.13
› Watch video

NASA Public Affairs Officer Kelly Humphries interviews astronaut Shannon Walker who served as an Expedition 24/25 flight engineer in 2010. She talks about preparations station crew members make before leaving the International Space Station.

She also describes what the crew is experiencing in the Soyuz spacecraft when the vehicle undocks and lands. Just before re-entering the atmosphere the Soyuz vehicle separates into three modules with the descent module returning the three crewmembers to Earth. The orbital module, filled with trash, and the propulsion and instrumentation module are destroyed during the fiery reentry into Earth's atmosphere.

As the descent module descends into the atmosphere the Soyuz deploys its parachutes. An instant before the Soyuz hits the ground it fires rockets to soften the landing.
