‘Enormous step forward’ as NASA lands rover on Mars

US: NASA successfully landed its $2.5 billion Mars Science Laboratory and Curiosity rover on the surface of the Red Planet on early Monday morning , marking the most ambitious attempt to reach Mars in history.

“Touchdown confirmed,” said a member of mission control at NASA’s Jet Propulsion Laboratory as the room erupted in cheers. “We are wheels down on Mars. Oh, my God.” A dusty image of the rover’s wheel on the surface, taken from a rear camera on the vehicle, confirmed the arrival of the car-sized rover and its sophisticated toolkit designed to hunt for signs that life once existed there.

A second image arrived within seconds, showing the shadow of the rover on Mars.

When the landing was announced after a tense, seven-minute process known as entry, descent and landing, the room filled with jubilation as the mission team cheered, exchanged hugs and chief scientists handed out Mars chocolate bars. President Barack Obama described the feat as a singular source of American pride.

“The successful landing of Curiosity -- the most sophisticated roving laboratory ever to land on another planet -- marks an unprecedented feat of technology that will stand as a point of national pride far into the future,” he said in a statement.

“It proves that even the longest of odds are no match for our unique blend of ingenuity and determination.” Charles Bolden, the NASA administrator, echoed that sentiment and applauded all the nations who contributed to science experiments on board the rover.

“It is a huge day for the nation, it is a huge day for all of our partners who have something on Curiosity and it is a huge day for the American people,” Bolden said.

Obama’s science advisor John Holdren described the landing as “an enormous step forward in planetary exploration. Nobody has ever done anything like this. We are actually the only country that has landed surface landers on any other planet,” he told NASA television.

“But this lander is vastly bigger, vastly more capable and much more complicated to bring in,” he added. “It was an incredible performance.” However, success was anything but certain with this first-of-its-kind attempt to drop a six-wheeled chemistry lab by rocket-powered sky crane on an alien planet. NASA’s more recent rover dropoffs were done with the help of airbags.

In the final moments, the spacecraft accelerated with the pull of gravity as it neared Mars’ atmosphere, making a fiery entry at a speed of 13,200 miles (21,240 kilometers) per hour and then slowing down with the help of a supersonic parachute.

After that, an elaborate sky crane powered by rocket blasters kicked in, and the rover was lowered down by nylon tethers, apparently landing upright on all six wheels.

Scientists do not expect Curiosity to find aliens or living creatures. Rather they hope to use it to analyze soil and rocks for signs that the building blocks of life are present and may have supported life in the past.

The project also aims to study the Martian environment to prepare for a possible human mission there in the coming years.
