NOVA scienceNOW: Can We Make It to Mars?

Hosted by Neil DeGrasse Tyson, this program from PBS examines the prospect of sending humans on a trip to Mars that could last as long as two to three years. Though the dangers of this potential journey include bone and muscle deterioration, cosmic radiation, and the threat of meteoroids, new scientific innovations are being designed to circumvent such problems. The episode also features scientist Vandi Verma, who is part of the team responsible for directing Mars rovers over the planet's harsh terrain.
