Space Exploration: Apollo Program & Cosmic Radiation | Trajectory | Free Documentary

Today, although a cloud of satellites surrounds the planet, many records set during the early decades of space exploration remain unsurpassed. It's more than forty years since the last man walked on the moon and the world no longer has a reusable spacecraft. Trajectory looks at milestones in space exploration along with the latest scientific and commercial developments.

Space Milestones:
- The Apollo Program Begins: At the very beginning of NASA’s moon project things go wrong.
- Caves: ESA's special training program for astronauts.
- Planck: Mapping the Cosmic Microwave Background Radiation.
