Nasa's Curiosity rover successfully lands on Mars


The reaction from the Nasa control room as the rover landed

The US space agency has just landed a huge new robot rover on Mars.

The one-tonne vehicle, known as Curiosity, was reported to have landed in a deep crater near the planet's equator at 06:32 BST (05:32 GMT).

It will now embark on a mission of at least two years to look for evidence that Mars may once have supported life.

A signal confirming the rover was on the ground safely was relayed to Earth via Nasa's Odyssey satellite, which is in orbit around the Red Planet.

The success was greeted with a roar of approval here at mission control at the Jet Propulsion Laboratory (JPL) in Pasadena, California.

Picture from Curiosity rover The first pictures from Mars began to be fed back immediately; high-resolution images will come later

Within minutes, the robot was returning its first low-resolution images - showing us its wheels and views to the horizon. A first colour image of Curiosity's surroundings should be returned in the next couple of days.

Engineers and scientists who have worked on this project for the best part of 10 years punched the air and hugged each other.

The rover's Twitter feed announced: "I'm safely on the surface of Mars. GALE CRATER I AM IN YOU!!!"

The descent through the atmosphere after a 570-million-km journey from Earth had been billed as the "seven minutes of terror" - the time it would take to complete a series of high-risk, automated manoeuvres that would slow the rover from an entry speed of 20,000km/h to allow its wheels to set down softly.

The day I watched Curiosity being built in a clean room at Nasa's Jet Propulsion Laboratory in Pasadena last year, the rover's six wheels were lying on one work bench while the chassis stood on another and it was hard to believe the white-suited engineers could make sense of the maze of tubes and cabling.

But what they've created now stands on the red soil of Mars - and it's in one piece. In the hallway of a JPL building we were shown a full-size replica. Walking around it made me realise something difficult to grasp from the pictures and video: this is a beast of a machine, a kind of cosmic Humvee with instruments instead of weapons.

Sometimes Nasa public relations can appear bragging. Today it feels justified. Curiosity is all set to discover something remarkable about our strangest neighbour.

The Curiosity team had to wait 13 tense minutes for the signals from Odyssey and the lander to make their way back to Earth.

Data suggested the vehicle had hit the surface of Mars at a gentle 0.6m/s.

"It looked at least with my eyeball that we landed in a nice flat spot. Beautiful," said Adam Steltzner, who led the descent operation.

The JPL director, Charles Elachi, added: "Tonight was a great drama that was played. I felt like I was in an adventure movie but I kept telling myself this is real; and what a fantastic demonstration of what our nation and our agency can do."

That sense of national pride was picked up by US President Barack Obama's chief science adviser, John Holdren.

"Landing the Mars Science Laboratory rover Curiosity on the Red Planet was by any measure the most challenging mission ever attempted in the history of planetary exploration," he said.

"And if anyone has been harbouring doubts about the status of US leadership in space, well there's a one tonne automobile-sized piece of American ingenuity sitting on the surface of the Red Planet right now."

Curiosity - Mars Science Laboratory

Rover (Nasa)
  • Mission goal is to determine whether Mars has ever had the conditions to support life
  • Project costed at $2.5bn; will see initial surface operations lasting two Earth years
  • Onboard plutonium generators will deliver heat and electricity for at least 14 years
  • 75kg science payload more than 10 times as massive as those of earlier US Mars rovers
  • Equipped with tools to brush and drill into rocks, to scoop up, sort and sieve samples
  • Variety of analytical techniques to discern chemistry in rocks, soil and atmosphere
  • Will try to make first definitive identification of organic (carbon rich) compounds
  • Even carries a laser to zap rocks; beam will identify atomic elements in rocks

This is the fourth rover Nasa has put on Mars, but its scale and sophistication dwarf all previous projects.

Its biggest instrument alone is nearly four times the mass of the very first robot rover deployed on the planet back in 1997.

Curiosity has been sent to investigate the central mountain inside Gale Crater that is more than 5km high.

It will climb the rise, and, as it does so, study rocks that were laid down billions of years ago in the presence of liquid water.

The vehicle will be scouring Mount Sharp in the crater's centre looking for evidence that past environments could have favoured microbial life.

It is a region that Curiosity project scientist John Grotzinger told the BBC's Horizon programme reads like a "book about the early environmental history of Mars".

Scientists warn, however, that this will be a slow mission - Curiosity is in no hurry.

For one thing, the rover has a plutonium battery that should give it far greater longevity than the solar-panelled power systems fitted to previous vehicles.

"People have got to realise this mission will be different," commented Steve Squyres, the lead scientist of the Opportunity and Spirit rovers put on the surface in 2004.

"When we landed we only thought we'd get 30 sols (Martian days) on the surface, so we had to hit the ground running. Curiosity has plenty of time," he told the BBC.

Initially, the rover is funded for two Earth years of operations. But many expect this mission to roll and roll for perhaps a decade or more.

Join Jonathan Amos for a special Discovery programme on Curiosity from JPL on the BBC World Service at 19:30 BST, Monday. The programme will be available for download after broadcast.

Mars rover (Nasa)
  • (A) Curiosity will trundle around its landing site looking for interesting rock features to study. Its top speed is about 4cm/s
  • (B) This mission has 17 cameras. They will identify particular targets, and a laser will zap those rocks to probe their chemistry
  • (C) If the signal is significant, Curiosity will swing over instruments on its arm for close-up investigation. These include a microscope
  • (D) Samples drilled from rock, or scooped from the soil, can be delivered to two hi-tech analysis labs inside the rover body
  • (E) The results are sent to Earth through antennas on the rover deck. Return commands tell the rover where it should drive next and follow me on Twitter

    Well done NASA. Perhaps still not as eye catching as the Apollo missions but if you find Life or signs of previous life on Mars then that would make this the most important scientific mission of all time, period or full stop as we say in the UK. Well Done !!

    "People are entitled to their opinion, no?!

    I think this thread is a prime example of why that entitlement should be called into question.
    And you're completely entitled to that opinion too, no matter how laughable it may seem to many others.

    Whilst I wish this mission every success I cannot help but wonder if the money would not be better used on our planet.
    Homeless families living in storm drains under Las Vegas, people walking around with tooth aches and requiring simple routine operations all for the lack of money. Come on lets get it right here before we start exploring other galaxies.

    The moral implications of scientific action should always be under a watchful eye. Genetics and cloning for example have significant implications.

    However, space exploration should not be judged by anyone who believes that the universe got here by magic and that the 5 billion year old Earth is actually younger than Stonehenge.

    "Science is the product of the whole developed world, not just one nation".

    I applaud what NASA has achieved, But you seem to deny that any nation except the US has contributed to the sciences that made this possible. Scientists are proud of SCIENCE - there is certainly rivalry but not often this sort of bigoted bickering. Are you a scientist? I am.

    I don't get why comment 791 is an editor's pick. It is short-sighted, mean-spirited and inaccurate. First, we all benefit from space programs because they lead to new discoveries new products (memory foam, anyone?) or can spur widespread use of niche products (velcro). People will always be starving and there will always be poverty. This has been supported by more than just Republicans.

    Re Levelers comment,
    Which Republican Party does Barak Obhama belong too then?
    He authorised the continuation of the project. Instead of continually knocking human achievement, praise it and believe in the future.

    "those who support and encourage organisations like NASA and the ESA et al shouldn't turn on each other over something as trivial as flags.

    Excellent point.

    The Chinese have said repeatedly that the militarization of space is inevitable. They seem to be acquiring a taste for war at the same time that we Americans are slowly beginning to lose ours.

    Spending money to advance our knowledge is not a waste. Nasa should be congratulated on their achievements past and present regardless of which country you live in.

    On the other hand, spending money to feed starving people who will simply breed more starving mouths consuming even more resources, is a genuine waste of money, and actually makes the problem worse.

    Curiosity's landing was a massive relief for me so I can only imagine how tense it would have been in the control room. The method of landing appeared to be too complex and asking for trouble, but it worked! I'll eat my words with pleasure. Now get that thing a roamin' and let's see some data.

    Well Done!

    Thank you Jonathan Amos, a good job again reporting the really important stuff.

    There is a lack of serious science on the media, but at least we have your enthusiasm and knowledge.

    Just a shame the BBC TV news cannot find the time to mention this, but at the moment they don’t seem able to find the time for any news at all!

    Hopefully this will spur our current+future American Presidents+Congress to increase funding to NASA
    as we are the only country on Earth to land on Mars
    which is USA's biggest crowning world achievement since putting a man on Moon (along with Michael Phelps being the Greatest Olympian ever, of course ;)

    NASA is USA's greatest pride+glory

    Please Congress increase our funding for NASA!!!

    Space exploration is a vital investment. The number of non-space-faring races that survive is zero. Eventually humans have to take to space and $2.5 billion over 8 years is peanuts compared to the $6 billion spent on the US presidential race every four years. This is an amazing achievement.

    Re 1039.Kent C Strait
    Why is thinking freely "electing yourself to stand in judgement"? The point is "progress" is itself only an idea: read some basic philosophy and history, especially from the 20th century. I think the technical achievment of Curiosity is wonderful, but why do you need it to be in a ethical vacuum? Science MUST be judged morally; ask Oppenheimer!

    => Yes. Could it be that they'll be emigrating to Mars soon? Mind you, they'll soon find ways to wreck what's left of the place. Pluto next?

    Man achieves a fantastic feat of exploration and engineering, still, "It costs too much". That should NEVER factor into our pursuit of knowledge. There's other places you could money from, but when it comes to NASA and the like, they're woefully underfunded.

    Congratulations to all involved.
