Today is Super Tuesday in Politics and Super Tuesday in Space.
Today is Super Tuesday in America. While this is certainly exciting (Watch this video before you vote Trump), space fans have a big day as well. SpaceX will attempt again to launch a Falcon 9 with the SES-9 satellite payload after three failed attempts. Today's launch is scheduled for 6:35pm ET and will be broadcasted live online.
Sunday's scrubbed launch is in part attributed to tugboat that entered the safety zone in front of the Canaveral coast. This caused a delay and the liquid-oxygen got too warm. Warm is relative as the liquid oxygen in the Falcon 9 tanks is super-chilled to - 207 degrees celsius.
Later tonight, NASA will broadcast on NASA TV the return of astronaut Scott Kelly. At 10:15pm ET NASA will broadcast the deorbit burn and landing. The deorbit burn is scheduled at 10:32pm ET and the landing is planned at 11:25pm (10:25 a.m. on March 2, Kazakhstan time).
Scott Kelly spent a year on the ISS, setting a new record along with his Russian colleague Mikhail Kornienko spending 340 days in space. Both will travel back to earth in a Russian Soyuz spacecraft.
The NASA TV coverage is available online on the NASA TV site.
