Enormous step forward as NASA lands rover on Mars

NASA on Sunday successfully landed its $2.5 billion Mars Science Laboratory and Curiosity rover on the surface of the Red Planet, 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 adviser 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 drop offs 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.
It has already been collecting data on radiation during its eight and a half month journey following launch in November 2011 from Cape Canaveral, Florida.
Earlier on Sunday, Mars program director Doug McCuistion called the science “absolutely crucial” to finding out if Earthlings are alone, how Mars evolved from a wet to a dry planet and how accessible Mars may be for human explorers in the future.
“If we succeed, it will be one of the greatest feats in planetary exploration ever,” he told reporters. “Our success rate has been pretty darn good recently.”
Attempts by global space agencies since 1960 have resulted in a near 40 percent success rate in sending landers, orbiters or other spacecraft for flybys to Mars. NASA has the best record.

  1. I cant understand how it can be termed as Tremendous victory, thousands of billions rupees are being wasted for the unknown purposes . This bigger amount might be allocated to eliminate the poverty, oust billions of masses suffering starvation and bring the peace in this world. Plz focus on this world, where we all live, to facilitate all of us…

    • @Ahmad SDO – US and rest of the world already spent (ohh wasted) billions of $ in Pakistan, Afghanistan and other similar poor countries – but neither poverty, starvation nor peace is achieved – Americans are working to find another world for themselves where these Paki and Afgans cannot reach….. huh

  2. United States of America(Earth,Moon and Mars) Please check the presence of our visa agents&land mafia there!
