Space Exploration: Mars Curiousity & Satellite Swarms | 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:
- Project Gemini: Docking and EVA - In the final phase of the Gemini program NASA struggles with docking and spacewalks.
- Curiosity Roving Mars - On the surface of Mars the Curiosity rover is changing the way we think about the red planet.
