Don’t miss the launch of the @NASA_Orion test flight tomorrow at 7:05am EST – @NASA livestream #JourneytoMars

Don’t forget! Tomorrow the Orion Spacecraft will blast off on a test flight just after 7 am EST! NASA livestream of the launch here, starts at 4am! More info on the NASA Orion blog here (image credit).

Critical Step on Journey to Mars
The countdown is on for Thursday’s 7:05 a.m. EST launch of NASA’s new human spacecraft, Orion, on its first voyage to space. Lifting off aboard a Delta IV Heavy rocket, the un-crewed Orion will orbit 3,600 miles above Earth before splashing down in the Pacific. Meteorologists upgraded their outlook to a 70 percent chance of acceptable conditions. Orion is being designed to carry astronauts on exploration missions into deep space, including a trip to an asteroid and eventually to Mars.

Check out previous CauseScience posts about Orion.

Also, there is a great article on UniverseToday comparing heavy lift launch systems including the SLS!
