NASA's Space to Ground: A Star to Steer By | Week of Aug. 10, 2018

NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station. This week, German astronaut Alexander Gerst of ESA (European Space Agency) explored using a sextant with star maps as an emergency form of navigation in space. The study will provide insights that mission planners will use on future Orion spaceflight missions farther away from Earth.

Christa’s Lost Lessons Brought to Life

Challenger Center, in partnership with NASA and STEM on Station, worked to complete several of the lessons Christa McAuliffe had planned for the Challenger STS 51L Teacher in Space mission. Working with Astronauts Ricky Arnold and Joe Acaba, the demonstrations were filmed aboard the International Space Station and corresponding lessons were developed for classrooms.

Lesson topics include chromatography, effervescence, liquids in microgravity and Newton’s law. Several of the lessons were completed as originally planned by Christa and a few were reimagined based on materials available aboard the Space Station.

Sharon Christa McAuliffe (born Sharon Christa Corrigan; September 2, 1948 – January 28, 1986) was an American teacher from Concord, New Hampshire and one of the seven crew members killed in the Space Shuttle Challenger disaster.
