NASA’s Curiosity Rover Finds Bright Object on Mars

NASA/JPL-Caltech/MSSS(NEW YORK) -- During NASA’s Curiosity rover’s first scoop of Mars’ surface, the robot discovered more than just soil.

An image taken by Curiosity’s right Mast Camera (Mastcam) shows a small, bright object near the rover.  This was the first use of the scoop on the rover’s robotic arm, NASA said in a press release.

NASA is investigating what exactly the bright object is, but they believe it may be a piece of the rover itself.  They will not scoop anymore soil or use the arm until they determine what the shiny object is.

The image was taken on Oct. 7, the rover’s 61st day on Mars.  The rover is part of a two-year, $2.5 billion project to look for signs that Mars could once have had the chemical resources needed to support microbial life.

Mars Rover Curiosity to Take First Test Drive

NASA/JPL-Caltech(PASADENA, Calif.) -- The Mars rover Curiosity, which landed on the Martian surface on the night of Aug. 5, is about to take its first baby steps -- or test drive, or whatever your preferred metaphor is -- on the way to exploring the terrain around it.

Overnight, U.S. time, mission engineers at NASA’s Jet Propulsion Laboratory in California said they plan to send Curiosity the computer commands to send it on its first short trip.  If everything works, it will move forward three meters (about 10 feet), turn right 90 degrees, and then back up a little bit.

That’s it.  But the longest journey begins with a single step.  Ultimately, NASA said it hopes the rover will be able to travel more than 100 yards per day over at least a two-year period, probing the Martian landscape for signs that it might once have been a home to microbial life.

“You will definitely see tracks,” said Mike Watkins, the mission manager, in a teleconference.  The first drive will tell controllers the rover’s six wheels are working properly, that it can turn in place as designed, and that it’s ready to move on later this week.

The test drive should last about half an hour.  It should take place in mid-afternoon, Mars time, when it’s warmest and the rover’s parts don’t have to be heated up.  NASA hopes there will be no surprises.

“We want to park it in a place we’ve imaged with our stereo cameras,” said Watkins, “just to make sure there’s nothing there.”

Controllers said they will be more bold over time.  The rover is in good shape so far after its nail-biter of a landing (recall the references to “seven minutes of terror” NASA promised) though a small wind detector is damaged.

Meanwhile, it’s almost summer-like at Gale Crater, where Curiosity put down.  Engineers reported the soil around the rover reached an afternoon high temperature of 37 degrees Fahrenheit on a recent Martian day, then dropped overnight to 131 degrees below zero.

Mars Rover: NASA's Curiosity Spacecraft Sends Color Panorama

NASA/JPL-Caltech/MSSS(NEW YORK) -- The Mars rover Curiosity has been very busy on Twitter.

"Gale Crater Vista, in Glorious Color!" it tweeted today.

The tweets, of course, come from the press office at the Jet Propulsion Laboratory in Pasadena, Calif., mission control for the rover. It has more than 890,000 followers.

Curiosity's mission is to wander a Martian crater, looking for signs of whether it ever had the right chemistry, or building blocks, for microbial life. If anything ever lived there, Curiosity is equipped to find it.

Mission managers showed off the first color panorama today of the area where the rover landed, showing a pebble-strewn plain in the foreground and the rim of Gale Crater, slightly obscured by haze, on the horizon a few miles away. The crater was chosen as a landing target because it may have exposed bedrock -- a good place to look for life that was wiped out eons ago and, for the most part, buried over time.

Looking at the panorama, Dawn Sumner, a mission scientist from the University of California at Davis, enthused about how the ship made an almost pinpoint landing after a long, elliptical 350-million-mile trip to Mars.

"In the hills in the distance," she said, "you see these beautiful knolls, recording the history of Gale Crater. It's very exciting to think about getting there, but it's quite a ways away."

Curiosity, about the size of a small car, has now raised the mast on its top deck on which its highest-resolution cameras are mounted. Its next job, to be completed in the next couple of days, sounds fairly mundane: Mission Control will send an upgrade of its computer operating system.

"It's a little like upgrading the software on your computer at home," said mission manager Michael Watkins. Curiosity's current software, he said, was written for the landing phase of the mission; it must now be replaced with commands for roving.

It will still be days before engineers, satisfied the rover is ready, will actually move it from its landing spot.

So far, aside from the rusty hue in the pictures, scientists concede that Curiosity has landed in a place that looks eerily like Earth -- never mind that it's 150 million miles away, drier than dust and perpetually frozen.

"You would really be forgiven for thinking that NASA was trying to pull a fast one on you, and we actually put a rover out in the Mojave Desert and took a picture," said project scientist John Grotzinger. "The first impression you get is how Earthlike this seems, looking at that landscape."

NASA's Mars Curiosity Rover Lands Successfully on Planet

NASA/JPL-Caltech(PASADENA, Calif.) -- NASA's $2.5 billion Mars Curiosity Rover has landed on the surface of the red planet following an eight-month, 352-million-mile journey.  NASA says it received a signal from the rover after a plunge through the Martian atmosphere described as "seven minutes of terror."

A chorus of cheers and applause echoed through the NASA Jet Propulsion Laboratory just after 1:30 a.m. EDT Monday when it was confirmed the rover had landed successfully.

"Touchdown confirmed," said engineer Allen Chen.  "We're safe on Mars."

Minutes later, Curiosity beamed back the first pictures from the surface showing its wheel and its shadow -- cast by the afternoon sun -- giving earthlings their first glimpse of a touchdown on another world.

Mars Curiosity is NASA's latest and boldest attempt yet to go where robots -- but no man -- have gone before.  Before this mission -- formally known as the Mars Science Laboratory -- the U.S., Russia, Japan and Europe had sent 40 spacecraft to explore the fourth planet from the sun since the space age began.  Twenty-six had failed.

Curiosity, an intrepid chemistry set on wheels, packed with cameras and gadgets galore, was designed to look for signs that life once existed on Mars -- signs that Mars could once have had the chemical resources needed to support microbial life.  This could mean potential sources of water, food and energy that could someday support visiting humans from Earth.

The landing had been dubbed "Seven Minutes of Terror" by the engineers who figured out the best way to land.  Adam Steltzner, team leader for the entry, descent and landing of Curiosity, said that as the ship was in the planning stages and then heading to Mars, he found himself waking up in the middle of the night, thinking about the sequence of events that would have to go perfectly.

"The big trick is you are going 13,000 miles an hour," he said.  "You slam into the Martian atmosphere and you want to gracefully get the spacecraft down sitting quietly on the surface on her wheels, and all of that takes different changes in the configuration of the vehicle, 79 events that must occur."

Curiosity was set to land when Mars was 154 million miles from Earth.  It weighed 5,293 pounds on Earth -- the size of a small car and much bigger than the rovers Spirit and Opportunity, which were cushioned by airbags when they landed in 2004.  

Engineers quickly figured out that airbags would burst if they were tried on Curiosity.  So they designed it to be lowered to the Martian surface by a heat shield, then a parachute, then retro-rockets, and finally a sky crane -- something that had never tried before -- and that's what made this so scary for them.  Just one slip would mean $2.5 billion down the drain.

Now that the rover is safely on Mars, NASA hopes it will explore the planet for one Martian year, which is about 22 months on Earth.

Mars Rover On Final Approach for Landing Sunday Night

iStockphoto/Thinkstock (NEW YORK) -- NASA's Mars Curiosity Rover closed in on its target Sunday, all systems go for a landing on Mars late Sunday night (Monday morning at 1:31 a.m. EDT). If there's anxiety at the Jet Propulsion Laboratory in Pasadena, Calif., which controls the mission, one can understand.

Curiosity (the mission's formal name is Mars Science Laboratory) is the largest, most expensive and most ambitious Mars probe sent by the United States in a generation. It's been a decade in the making and ran up bills of $2.5 billion.

NASA is playing down expectations, but if the building blocks of life are buried in the Martian soil, Curiosity's miniature onboard chemistry laboratory is designed to pick them out.

"Can we do this? Yeah, I think we can do this. I'm confident," Doug McCuistion, head of the Mars exploration program at NASA headquarters, said Saturday. "We have the A-plus team on this. They've done everything possible to ensure success, but that risk still exists."

"We have to keep looking," said Andrew Kessler, a writer who spent three months covering the team that made the last successful landing, in 2008. "Every question leads to more understanding," said Kessler, the author of a book called "Martian Summer."

Curiosity weighed 5,293 pounds on Earth. It's the size of a small car and much, much bigger than the twin rovers Spirit and Opportunity, which landed on Mars in 2004, cradled in airbags. Curiosity is simply too big for that, so it will be lowered to the surface by a heat shield, then a parachute, then retro-rockets, and finally a rocket-powered sky crane. That's something engineers have never tried before -- and that's what makes this so scary for them.

"When people look at it, it looks crazy," says Adam Stelzner, an engineer who laid out the landing plans, in a video NASA produced about the landing. "Sometimes when we look at it, it looks crazy. It is the result of reasoned engineering thought. But it still looks crazy."

NASA says it thinks there's a 90 percent chance of a safe landing. If they're right, they say they hope Curiosity will explore for one Martian year -- about 22 months on Earth.

If Curiosity doesn't find evidence of life, scientists say it will mean very little. The half-dozen probes to land on Mars since 1976 have only explored a few square miles of the planet.

But what if it hits pay dirt? What if it really does find something? The results would probably not be conclusive, but they would be incentive for further exploration -- a tender subject at NASA because, hampered by budget cuts, it currently has no future Mars missions approved.

"If we don't ponder these things, then we're not asking ourselves the right questions," said Kessler, "and we're not looking to build bigger and better futures for ourselves."
