Trajectory: Milestones in Space Exploration - Episode 8: Rebuilding Project Apollo, Orbiting Carbon Observatory & Zero Gravity Training | Space Documentary

Trajectory looks at milestones in space exploration along with the latest scientific and commercial developments.

Space Milestones:
- Rebuilding Project Apollo: After the Apollo 1 disaster NASA resumes manned space flight
