Curiosity’s site for first drive pinpointed by team NASA
Washington: Researchers and engineers of NASA’s Curiosity rover mission have selected the first destination for their one-ton, six-wheeled mobile Mars laboratory, it has been revealed.
The target area, named Glenelg, is a natural intersection of three kinds of terrain.
“With such a great landing spot in Gale Crater, we literally had every degree of the compass to choose from for our first drive,” John Grotzinger, principal Curiosity investigator, said.
“We had a bunch of strong contenders. It is the kind of dilemma planetary scientists dream of, but you can only go one place for the first drilling for a rock sample on Mars. That first drilling will be a huge moment in the history of Mars exploration,” he said.
The trek to Glenelg will send the rover 1,300 feet (400 meters) east southeast of its landing site. One of the three types of terrain intersecting at Glenelg is layered bedrock, which is attractive as the first drilling target.
“We’re about ready to load our new destination into our GPS and head out onto the open road,” Grotzinger said.
“Our challenge is there is no GPS on Mars, so we have a roomful of rover-driver engineers providing our turn-by-turn navigation for us,” he said.
Prior to the rover’s trip to Glenelg, the team in charge of Curiosity’s Chemistry and Camera instrument, or ChemCam, is planning to give their mast-mounted rock-zapping laser and telescope combination a thorough checkout.
On Saturday night, ChemCam is expected to “zap” its first rock in the name of planetary science. It will be the first time such a powerful laser has been used on the surface of another world.
“Rock N165 looks like your typical Mars rock, about three inches wide. It’s about 10 feet away,” Roger Wiens, principal investigator of the ChemCam instrument from the Los Alamos National Laboratory in New Mexico, said.
“We are going to hit it with 14 millijoules of energy 30 times in 10 seconds. It is not only going to be an excellent test of our system, it should be pretty cool too,” he said.
Mission engineers are devoting more time to planning the first roll of Curiosity.
In the coming days, the rover will exercise each of its four steerable (front and back) wheels, turning each of them side-to-side before ending up with each wheel pointing straight ahead.
The choice of destination was described during a media teleconference on Aug. 17.
