Students challenged to plan manned mission to Mars

These color-enhanced views of Deimos, the smaller of the two moons of Mars, were taken on Feb. 21, 2009, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. Deimos is about 7.5 miles in diameter. Deimos has a smooth surface due to a blanket of fragmental rock or regolith, except for the most recent impact craters. It is a dark, reddish object, very similar to Mars' other moon, Phobos.

Humanity's quest to send astronauts to Mars may get a boost from a student design competition being held this week.

The Caltech Space Challenge, which runs from Monday through Friday (March 25-29) at the university's campus in Pasadena, asks two teams of students from around the world to design a manned mission to Phobos or Deimos, Mars' two tiny moons.

"This is a technical feat that, by necessity, will spark innovation the world over," Nick Parziale, a Ph.D. student in aeronautics at Caltech and leader of one of the teams, said in a statement. "We hope the Caltech Space Challenge serves as a reminder that these incredibly difficult problems are tractable, and that these passionate and dedicated students are just the women and men for the job."

A total of 32 graduate and undergraduate students representing 21 universities and 11 different countries are participating in the competition, Caltech officials said. Scientists and engineers from Caltech, NASA's Jet Propulsion Laboratory in Pasadena and a number of aerospace firms will advise the student teams and judge their final designs, which will be presented Friday.

Many scientists view Phobos and Deimos as potential stepping stones to Mars itself, as well as locations from which astronauts could efficiently operate robots exploring the Red Planet's surface.

The two moons are both tiny, with Phobos measuring 14 miles (22 kilometers) across and Deimos just 8 miles (13 km). They're probably former asteroids that Mars' gravity captured long ago, researchers say.

NASA is looking into sending astronauts to Phobos or Deimos as part of a broad investigation of manned Mars mission options. In 2010, President Barack Obama directed the space agency to get humans to the vicinity of the Red Planet by the mid-2030s.

Students participating in the design competition hope their work brings a manned journey to Mars a little closer to reality.

"Sending humans to the neighborhood of Mars, and back, is going to be one of the most challenging engineering feats ever attempted," Jason Rabinovitch, another Caltech aeronautics Ph.D. student and leader of the competition's other team, said in a statement.

"The Caltech Space Challenge is our way to continue to support and advance what is bound to be a long process of design, development and innovation leading to human footprints on Martian soil," Rabinovitch added.

Public lectures associated with the design challenge will be given Monday through Wednesday. The public is also invited to attend the competition's final presentations on Friday afternoon. More details on the student contest are available at the Caltech Space Challenge website.
