Curiosity Rover

NASA’s Curiosity Mars rover got a bit of help from the European Space Agency (ESA) in October. Beaming data back to Earth from the surface of the Red Planet is often tricky, and Curiosity regularly uses satellites to act as relays when a proper line of sight isn't available. On October 6, the ESA probe Mars Express took up the slack by relaying data and images for the rover as part of an ESA-NASA support agreement.  Read More

NASA’s Curiosity Mars rover is now sending back weather reports and radiation measurements. Using the Rover Environmental Monitoring Station (REMS) instrument built by Spain’s Centro de Astrobiologia (CAB), the nuclear-powered robot has been taking measurements of atmospheric pressure, temperature, wind speed and other factors to better understand the Martian environment in hopes of finding out whether life could still exist on the Red Planet.  Read More

NASA’s Curiosity Mars rover has sniffed the Martian air and now its Sample Analysis at Mars (SAM) instrument has taken its first taste of soil. The microwave-size internal laboratory of the nuclear-powered rover received its first sample on November 9 and spent the next two days analyzing it. Taken at the Rocknest area of Gale Crater, the purpose of the sampling is to study soil composition with a special emphasis on seeking organic molecules.  Read More

NASA’s Curiosity rover has taken a whiff of Martian air at the "Rocknest" site in Gale Crater. The robot explorer's Sample Analysis at Mars (SAM) instruments are now being used to measure the constituent elements of the atmosphere and their isotopes with the aim of providing insights into the history of the Red Planet and its chances of having once supported life.  Read More

NASA’s Curiosity Mars rover took its first soil sample last week. The unmanned explorer used its robotic arm to scoop up a bit of the Martian surface, which it then sieved. A baby-Aspirin sized portion was subsequently deposited into its internal laboratory for analysis by the Chemistry and Mineralogy (CheMin) instrument, to determine what minerals it contains.  Read More

The object that NASA’s Curiosity Mars rover found on Sunday is probably a piece of plastic that fell off the unmanned exploration vehicle. According to mission control at the Jet Propulsion Laboratory (JPL) at Pasadena, California, the object is “benign” and poses no likely threat to continuing the mission. However, the JPL rover team has not yet definitely identified the object and will continue investigating for another day.  Read More

NASA’s unmanned Mars rover Curiosity took a pause in its activities after spotting a bright object. As yet unidentified, it was spotted while Curiosity was collecting its first soil samples. Fearing that the object might be a part of Curiosity itself that fell off, mission control at the Jet Propulsion Laboratory (JPL) in Pasadena, California has suspended Curiosity’s exploration until the object is identified.  Read More

Scooping up a handful of dirt may seem simple, but for a robot operating on another planet, it’s a major operation. NASA’s Curiosity Mars rover is making itself ready to collect its first soil sample at an area called “Rocknest.” The preparations involve testing the nuclear-powered rover’s motorized scoop and cleaning out its Chemistry and Mineralogy (ChemMin) and Sample Analysis at Mars (SAM) laboratories of any terrestrial contaminants before receiving soil samples.  Read More

Artist's concept features NASA's Curiosity rover, which checked in foursquare this week (I...

NASA launched a strategic partnership with location-based social networking site foursquare in 2010 with the first-ever check-in from the International Space Station (ISS) by astronaut Doug Wheelock. Now the space agency has gone one better with the first check-in on another planet thanks to its Curiosity Mars rover.  Read More

NASA’s unmanned Curiosity rover has found the most direct evidence to date that ancient Mars once had running water. The robot explorer discovered rock outcroppings thrusting from the Martian surface that are the remains of an ancient stream bed consisting of water-worn gravel that was washed down from the rim of Gale Crater where the nuclear-powered rover landed. This means that Mars was once a much wetter place and increases the chances that it once harbored life ... or still does.  Read More
