Robot rover nears Mars

BBC Online
Nasa yesterday said the big robot rover it is sending to Mars looks in excellent shape for its Monday landing.
The vehicle, known as Curiosity, was launched from Earth in November last year and is now nearing the end of a 570-million-km journey across space.
To reach its intended touch-down zone in a deep equatorial crater, the machine must enter the atmosphere at a very precise point on the sky. Engineers told reporters on Thursday that they were close toabulls-eye.
A slight course correction - the fourth since launch -was instigated last Saturday, and the latest analysis indicates Curiosity will be no more than a kilometre from going straight down its planned "keyhole".
"We are about to land a small compact car on the surface with a trunk-load of instruments. This is a pretty amazing feat getting ready to happen. It's exciting, it's daring - but it's fantastic," said Doug McCuistion, the head of Nasa's Mars programme.
Curiosity - also known as the Mars Science Laboratory - is the biggest, most sophisticated Mars rover yet.
It will study the rocks inside Gale Crater, one of the deepest holes on Mars, for signs that the planet may once have supported microbial life.
The $2.5b mission is due to touch down at 05:31 GMT Monday 6 August.
It will be a totally automated landing.
Engineers at the Jet Propulsion Laboratory in Pasadena, California, can only watch and wait.
The vast distance between Mars and Earth means there is a 13-minute lag in communications, making real-time interventionimpossible.
Nasa has had to abandon the bouncing airbag approach to making soft landings.
This technique was used to great effect on the three previous rovers - Sojourner, Spirit and Opportunity.
But at nearly a tonne, Curiosity is simply too heavy to be supported by inflated cushions.
Instead, the mission team has devised a rocket-powered, hovering crane to lower the rover to the surface in the final moments of its descent.
The team is also keeping a sharp eye on the Martian weather and any atmospheric conditions that might interfere with the
descent manoeuvres.
It is the time of year when winds can kick up huge clouds of dust, and a big storm was spotted this week about 1,000 km from the landing site. But Nasa expects this storm to dissipate long before landing day.
The first black-and-white images of the surface taken by Curiosity should be returned to Earth in the first hours after touch down, but the mission team do not intend to rush into exploration.
The rover has a plutonium battery that should give it far greater longevity than the solar-panelled power systems on previous vehicles.
