NASA releases video of Mars rover descent

NASA's Curiosity rover has transmitted a low-resolution video showing the last 2 1/2 minutes of its white-knuckle dive through the Mars 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.

NASA celebrated the precision landing of a rover on Mars and marvelled 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 on Sunday night after an eight-month, 566-million kilometre journey.

It parked its six wheels about 6 1/2 kilometres 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 tonne, and the thin Martian atmosphere offers little friction to slow down a spacecraft.

Curiosity had to go from 20,920km/h 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 3.2km/h.
