The next step is to send astronauts on a two-way trip to Mars to further study its surface, determine whether life once existed there and prepare for potential habitation, said Sam Scimemi, director of NASA’s International Space Station Program.

“It takes a year or more for a robot to do what a person can do in a matter of days,” he said.

However, a human Mars mission presents technological and financial challenges, the officials said.

NASA scientists continue to study methods for landing a 40-ton spacecraft traveling at a speed of 13,000 miles per hour on Mars. The Mars rover weighed just one ton.
