The 78-second journey to the surface ended a 12-day wait since Spirit’s landing at Gusev Crater on January 4, during which the rover had been unfolding itself, checking its systems and turning 115 degrees to line up with the most favourable exit ramp. It is now parked next to the lander, where it will stay for three days while scientists conduct experiments on nearby soil and rocks.
At the weekend, Spirit will set off on its first long drive, probably towards a crater approximately 250 metres away. If all goes well, the plan is then to turn right at the crater and head for the hills about 3km (1.9 miles) away.
The success, which scientists toasted with champagne, came the day after President Bush announced NASA budget increases of $1 billion (£549 million) a year to support efforts to establish a permanent Moon base and send a manned mission to Mars.
Charles Elachi, director of Nasa’s Jet Propulsion laboratory in Pasadena, California, which built and operates Spirit said: “Less than 24 hours ago, President Bush committed our nation to a sustained mission of space exploration. We at NASA move awfully fast. We have six wheels in the dirt. Mars is our sandbox and we’re ready to play and work.”
Though the first drive took just 78 seconds, at a speed of 4cm per second, Spirit then had to turn its main antenna towards Earth before it could confirm its new position and send back pictures. Scientists at mission control cheered as the good news arrived at 9.50 am GMT.
Russia could send a man to Mars at a tenth of the cost of American plans, according to one of Russia’s top space officials, Leonid Gorshkov, the chief designer of the state-controlled Energia company, which built the core of the International Space Station and now wants to re-enter the space race. “Technically, the first flight to Mars could be made in 2014,” Dr Gorshkov said.
Today Spirit’s science team will join European colleagues in an unprecedented experiment when Europe’s Mars Express orbiter flies directly overhead. Spirit will look up into the Martian atmosphere with its panoramic cameras and a thermal emissions spectrometer while Mars Express looks at the same portion from above with its instruments. Data from the spacecraft will be combined to create the most comprehensive picture yet of the atmosphere on Mars.
Spirit’s sister rover, Opportunity, is scheduled to land next Sunday at the Meridiani Planum region of Mars.
A dark and mysterious side to Mars that has never been seen before was revealed by NASA’s Opportunity rover yesterday in a remarkable series of pictures beamed to Earth within hours of its faultless landing.
The images of Meridiani Planum, where NASA’s second robotic probe touched down at 5.05 am, show a strange plain covered in fine-grain maroon soil much darker than anything yet observed on Mars, and an outcrop of grey bedrock that could offer clues to the planet’s geological past.
These odd features are ideal for the rover’s mission – the search for evidence that the planet was once wet and suitable for life – and led one scientist to describe the landing site as “the promised land”.
The slabs of protruding rock could contain grey haematite, a form of iron oxide that is normally formed in the presence of water. They are the rover’s most likely first target. Meridiani Planum was chosen for Opportunity’s landing as orbiting spacecraft had picked up traces of the mineral in the region. Steve Squyres, the rover missions’ chief scientist, said that he was flabbergasted by the pictures, which look different from those taken by Opportunity’s twin, Spirit, at Gusev Crater.
“Opportunity has touched down in a bizarre, alien landscape,” he said. “I’m astonished. I’m blown away. It looks like nothing that I’ve ever seen in my life. Holy smokes, I’ve got nothing else to say.”
The rover’s textbook landing brightened the mood at NASA’s jet propulsion laboratory in Pasadena, California, where the team has been working furiously since Wednesday to diagnose and correct a potentially catastrophic fault aboard Spirit, which landed three weeks ago.
Engineers said that they had established the root cause of its problems and had stabilised the robot by switching off a malfuctioning memory system.
Even so, it may be three weeks or more before Spirit can resume scientific investigations, and the memory problem may prevent it from recovering full operational capacity.
