What Makes Us Human?

Scientists have struggled for centuries to pinpoint the qualities that separate human beings from the millions of other animal species that have evolved on this planet.

He'll trace some of the crucial steps that transformed cave men to accountants, and find out if any of his own DNA came from a Neanderthal ancestor.

Can We Make It to Mars?

Can humans survive a trip to Mars and back that could take two to three years? This episode of NOVA scienceNOW examines all of the perils of this journey, including deadly meteoroids, bone and muscle deterioration, and cosmic radiation.

Among the innovations covered are meteoroid-proof materials, new space foods and spacesuits, and novel modes of transport, such as plasma rockets. This episode also profiles young female scientist and daredevil Vandi Verma, part of the team that drives the Mars rovers on the martian surface.
