Mars: The Secret Science

Meet the scientists and explorers determined to send humans to Mars. As NASA builds its first crewed spacecraft for Mars and visionaries devise off-world colonies, our future on the Red Planet might begin sooner than we think.

NASA’s Curiosity mission is on a quest to find life on Mars, but what they uncover could reveal far more than what anyone expected.

The possibility of a human civilization on Mars has seemed like a fantasy -- until now. We go behind-the-scenes at SpaceX, where Elon Musk shows us just how real this fantasy can be.

We examine what lies beneath Mars’s surface and uncover answers to some of the mysteries that have stumped scientists for decades.

Landing humans on Mars will be hard; NASA scientists are designing innovative rockets and training the pilots.

The Curiosity Rover is the largest, heaviest, and most technologically advanced piece of equipment ever to go to Mars. We go inside NASA to discover what it took to build it.
