The successful first flight test of NASA?s Orion spacecraft on Dec. 5 not only was a historic moment for the agency ? but also was a critical step on NASA?s Journey to Mars.
Orion rode to space from Cape Canaveral Air Force Station on a Delta IV heavy rocket with no crew, but loaded with about 1,200 sensors.
The flight test basically was a compilation of the riskiest events that will happen when astronauts fly on Orion on deep space missions.
