Curiosity Mars rover to land on the red planet tomorrow

The Mars Science Laboratory, which carries the rover, aims to find out if there is life on Mars – and it arrives near the planet’s surface tomorrow.

ARE WE ALONE? Or was there life on another planet?

NASA’s $2.5 billion dream machine, the Mars Science Laboratory, aims to take the first steps toward finding out when it nears Mars’s surface on Monday.


The planet is Earth’s closest neighbour, and scientists have found signs of water there, hinting that some form of life was likely to have existed there at some point even though Mars is now a dry place with a thin atmosphere, extreme winters and dust storms.

NASA’s Mars Science Laboratory carries a one-ton rover, Curiosity – the size of a small car and the biggest ever built for planetary exploration – and a complex toolkit will zap rocks and drill soil in the hunt for microbial fossils.

The landing of the nuclear-powered spacecraft is the boldest ever attempted, and involves penetrating the atmosphere, slowing down with the help of a supersonic parachute and dropping down gently with tethers from a rocket-powered sky crane.


NASA said it expects to know of the landing at 5.31 GMT Monday, about 14 minutes after the landing actually happens due to the time it takes for spacecraft signals to travel from Mars to Earth.

The Mars Science Laboratory began its journey to the Red Planet more than eight months ago when it launched from the Florida coast in late November 2011.

“It gets scarier every day,” said Doug McCuistion, director of NASA’s Mars Exploration Program. He noted that only about 40 percent of past attempts by global space agencies to send spacecraft to Mars have succeeded.

Can we do this? Yeah, I think we can do this. I am confident the team has done an amazing job. We have the A-plus team on this. They have done everything possible to ensure success. But that risk still exists. It is going to be tough.


NASA has detailed the final minutes of the complex landing in an Internet video called Seven Minutes of Terror.

The landing site for the rover is a flat area known as Gale Crater, which lies near a mountain that scientists hope the rover will be able to climb in the search for sediment layers that could be up to a billion years old.

One potential factor of concern, the weather, appears to be cooperating after a nearby dust storm spotted days ago dissipated, MSL deputy project scientist Ashwin Vasavada told reporters.

Mars is playing nice and we are going to get good conditions for Sunday.

Vasavada said the dust storm near the landing site has evolved into a “fairly harmless cloud of dust” that probably will not reach Gale Crater by the time of the landing.

He said it was not “expected to affect entry, descent and landing in any meaningful way.”

If the landing goes according to plan, NASA hopes to have some low-resolution black and white images taken from cameras on the rear of the rover shortly afterward.

More images will follow in the coming days. Engineers on Earth will spend most of August remotely checking out systems on the vehicle.

Curiosity may start to roll for its first drive in September, with its first scoop samples expected late in the month and its first drilling attempt in October or November.

Pick ourselves up

If the landing fails, McCuistion vowed that the NASA program would continue its efforts to explore Mars.

We will pick ourselves up and dust ourselves off. We will look at this and do something again. We will do it again, this will not be the end.

“Human spirit gets driven by these kinds of challenges and these are the kinds of challenges that force us, drive us to explore,” he added. ”To explore our surroundings, to understand what is out there, and obviously look at ‘Are we alone?’”
