7 Minutes Of Terror End In Jubilation

7 Minutes Of Terror End In Jubilation After a more than 300-million mile journey and "7 Minutes of Terror," NASA's Curiosity rover safely landed on the surface of Mars.

The vehicle, loaded with the most-sophisticated instruments ever used off Earth, touched down at 1:32 a.m. New York time.

Thanks to a remarkable combination of engineering and mathematics, a NASA satellite in orbit around Mars was able to capture a photo as Curiosity fell from space towards Mars' surface traveling at 13,200 miles per hour.



"If HiRISE took the image one second before or one second after, we probably would be looking at an empty Martian landscape," said Sarah Milkovich, HiRISE investigation scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif.

"When you consider that we have been working on this sequence since March and had to upload commands to the spacecraft about 72 hours prior to the image being taken, you begin to realize how challenging this picture was to obtain."

NASA celebrated the precision landing of a rover on Mars and marveled over the mission's first photographs Monday.

Curiosity, a roving laboratory the size of a compact car, landed right on target late Sunday night after an eight-month, 352-million-mile journey.

Cheers and applause echoed through NASA's Jet Propulsion Laboratory, and engineers hugged, high-fived and thrust their fists in the air after signals from space indicated the vehicle had survived the harrowing descent through Mars' pinkish atmosphere.

JPL Director Charles Elachi likened the team to Olympic athletes: "This team came back with the gold."

"Everybody in the morning should be sticking their chests out and saying, 'That's my rover on Mars,'" NASA Administrator Charles Bolden said on NASA TV.

Extraordinary efforts were needed for the landing because the rover weighs one ton, and the thin Martian atmosphere offers little friction to slow a spacecraft down. Curiosity had to go from 13,000 mph to zero in seven minutes, unfurling a parachute, then firing rockets to brake.

At the end of what NASA called "seven minutes of terror," the vehicle settled into place almost perfectly flat in the crater it was aiming for.

"We have ended one phase of the mission much to our enjoyment," mission manager Mike Watkins said. "But another part has just begun."

The nuclear-powered Curiosity will dig into the Martian surface to analyze what's there and hunt for some of the molecular building blocks of life, including carbon.

It won't start moving for a couple of weeks, because all the systems on the $2.5 billion rover have to be checked out. Color photos, panoramas and video will start coming in the next few days.
