Curiosity: is there life on Mars?
With a mixture of nerves and confidence, NASA has landed its largest ever robotic rover on Mars, where it will search for signs that life may once have existed on the planet.
The 2.4 billion dollar Mars Science Laboratory, featuring a car-sized rover called Curiosity, landed on Mars at 3.31pm Sydney time.
Scientists do not expect Curiosity to find living creatures but they hope to use it to analyse soil and rocks for signs that the building blocks of life are present and may have supported life in the past.

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 ton, and the thin Martian atmosphere offers little friction to slow a spacecraft down. 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.
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.
The nuclear-powered Curiosity will dig into the Martian surface to analyse 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 $US2.5 billion ($A2.37 billion) rover have to be checked out. Colour photos and panoramas will start coming in the next few days.
But first NASA had to use tiny cameras designed to spot hazards in front of Curiosity's wheels. So early images of gravel and shadows abounded. The pictures were fuzzy, but scientists were delighted.
The photos show "a new Mars we have never seen before", Watkins said. "So every one of those pictures is the most beautiful picture I have ever seen."
In one of the photos from the close-to-the-ground hazard cameras, if you squinted and looked the right way, you could see "a silhouette of Mount Sharp in the setting sun", said an excited John Grotzinger, chief mission scientist from the California Institute of Technology.
A high-resolution camera on the orbiting seven-year-old Mars Reconnaissance Orbiter, flying 340km directly above the plummeting Curiosity, snapped a photo of the rover dangling from its parachute about a minute from touchdown. The parachute's design can be made out in the photo.
Curiosity is the heaviest piece of machinery NASA has landed on Mars, and the success gave the space agency confidence that it can unload equipment that astronauts may need in a future manned trip to the red planet.
The landing technique was hatched in 1999 in the wake of devastating back-to-back Mars spacecraft losses. Back then, engineers had no clue how to land super-heavy spacecraft. They brainstormed different possibilities, consulting Apollo-era engineers and pilots of heavy-lift helicopters. (AAP)
