The head of the National Aeronautics and Space Administration, or NASA, said that the space agency is on track to land people on Mars in the 2030s.
Charles Bolden is the administrator for NASA. He said that five years ago, President Obama set that goal for the space agency.
Speaking at the Humans to Mars Summit 2015, Bolden said “This plan is clear, this plan is affordable and this plan is sustainable.”
Buzz Aldrin was the second man to step on the moon. He is retired from NASA but is working to get humans to Mars. He told the summit that “we need to stimulate the public to be supportive” of a U.S. mission to Mars. The program, Mr. Aldrin said, needs to develop in a series of stages, or steps, over several years.
NASA engineer Bret Drake said that is the idea that several private companies have offered.
Explore Mars, Inc., is the group that organized the Humans to Mars summit last week. The group released a study on the steps required to send people to Mars.
They are a new Space Launch System, Orion spacecraft, a deep space environment for astronauts to live in, and new methods for entry, descent and landing. Other new technologies needed are solar electric propulsion for power and a vehicle that could land people on Mars.
NASA is already working with private partners to develop the technology needed to get humans to Mars. They are working to develop advanced propulsion and habitation—where and how people will live on Mars once they get there.
One example is Lockheed Martin’s Stepping Stones plan. It calls for beginning flights to the International Space Station using today’s vehicles and Orion spacecraft. Later flights will land on Deimos, one of Mars’ two moons.
Last week NASA also announced a “Journey to Mars Challenge.” The agency is asking for ideas from the public on how to get people to Mars and how they can stay. The ideas could be about shelter, food, water, breathable air, communication, exercise, social relations and medicine. NASA said people are “encouraged to consider innovative and creative elements beyond these examples.”
The Mars rovers Curiosity and Opportunity are already providing much information as they move across the Martian surface. It is already known that at one point in time Mars had conditions that could have supported life.
NASA’s Charles Bolden said that Mars “just might help us to unravel the age old mystery about whether life exists beyond Earth.”
