NASA Curiosity Rover Sends Back 1st Color Picture
PASADENA, Calif. (AP) - NASA’s Curiosity rover has transmitted its first color photo and a low-resolution video showing the last 2 1/2 minutes of its white-knuckle dive through the Martian atmosphere, giving earthlings a sneak peek of a spacecraft landing on another world.
As thumbnails of the video flashed on a big screen on Monday, scientists and engineers at the NASA Jet Propulsion let out "oohs" and "aahs." The recording began with the protective heat shield falling away and ended with dust being kicked up as the rover was lowered by cables inside an ancient crater.
It was a sneak preview, since it’ll take some time before full-resolution frames are beamed back depending on other priorities.
The full video "will just be exquisite," said Michael Malin, the chief scientist of the instrument.
The color photo from the ancient crater where Curiosity landed showed a pebbly landscape and the rim of Gale Crater off in the distance. Curiosity snapped the photo on the first day on the surface after touching down on Mars Sunday night.
The rover took the shot with a camera at the end of its robotic arm, which remained stowed. The landscape looked fuzzy because the camera’s removable cover was coated with dust that kicked up during the descent to the ground.
NASA celebrated the precision landing of a rover on Mars and marveled over the mission’s flurry of photographs - grainy, black-and-white images of Martian gravel, a mountain at sunset and, most exciting of all, the spacecraft’s white-knuckle plunge through the red planet’s atmosphere.
Curiosity, a roving laboratory the size of a compact car, landed right on target late Sunday after an eight-month, 352-million-mile journey. It parked its six wheels about four miles from its ultimate science destination - Mount Sharp, rising from the floor of Gale Crater near the equator.
Extraordinary efforts were needed for the landing because the rover weighs one ton, and the thin Martian atmosphere offers little friction to slow down a spacecraft. Curiosity had to go from 13,000 mph to zero in seven minutes, unfurling a parachute, then firing rockets to brake. In a Hollywood-style finish, cables delicately lowered it to the ground at 2 mph.
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.
