Used Parachute From Curiosity Rover Flaps In The Wind On Mars
2013-04-03 14:10:32

NASA's Jet Propulsion Laboratory Photos from NASA's Mars Reconnaissance Orbiter show how the parachute that helped NASA's Curiosity rover land on Mars last summer has subsequently changed its shape on the ground. The images were obtained by the High Resolution Imaging Science Experiment (HiRISE) camera on Mars Reconnaissance Orbiter. Seven images taken by HiRISE between Aug. 12, 2012, and Jan. 13, 2013, show the used parachute shifting its shape at least twice in response to wind....

Copernicus crater
2013-04-03 04:40:58

April Flowers for redOrbit.com - Your Universe Online Large impacts on the Moon produce unimaginable amounts of energy; however, they may not wipe the mineralogical slate clean. New research, led by Brown University geoscientists, has discovered a rock body with a distinct mineralogy snaking 18 miles across the floor of Copernicus crater — a 60-mile-wide feature on the Moon's near side. Mineralogical signatures of rock present before the impact that created the crater appear to...

Lunar Reconnaissance Orbiter Detects Hydrogen, Mercury From Twin GRAIL Impacts
2013-03-27 12:00:36

redOrbit Staff & Wire Reports - Your Universe Online Using instruments on board the Lunar Reconnaissance Orbiter (LRO), NASA officials were able to detect mercury and hydrogen in the gas plumes that arose following the impact of the twin Gravity Recovery and Interior Laboratory (GRAIL) spacecraft last December, the US space agency announced on Tuesday. The LRO´s Lyman Alpha Mapping Project (LAMP) also measured the time evolution of those gases as they rapidly expanded into the...

Science Investigations Resumed By Curiosity
2013-03-26 11:33:56

NASA's Jet Propulsion Laboratory NASA's Mars rover Curiosity has resumed science investigations after recovery from a computer glitch that prompted the engineers to switch the rover to a redundant main computer on Feb. 28. The rover has been monitoring the weather since March 21 and delivered a new portion of powdered-rock sample for laboratory analysis on March 23, among other activities. "We are back to full science operations," said Curiosity Deputy Project Manager Jim Erickson of...

Curiosity Heading Towards Spring Break
2013-03-25 12:29:33

Lee Rannals for redOrbit.com - Your Universe Online NASA's Curiosity rover has been hard at work for seven months now, and the Mars tourist is about to get its own Spring Break. The Red Planet will be passing almost directly behind the Sun from Earth's perspective in April for two weeks, so NASA will be putting the Curiosity mission on hold. The sun is capable of disrupting radio transmissions between the two planets during the near-alignment, so NASA is holding off sending commands to...

NASA Lunar Orbiter Captures Stunning Images Of Twin GRAIL Impacts
2013-03-21 07:24:08

WATCH VIDEO: [LAMP Observes GRAIL Impact] Lawrence LeBlond for redOrbit.com - Your Universe Online After spending nearly a year in lunar orbit studying the moon´s interior, two NASA spacecraft, known as GRAIL A (Ebb) and GRAIL B (Flow), were ordered to embark on a final mission that would hopefully give scientists one last bit of data about the moon´s composition. The twin spacecraft, which were launched in September 2011 and arrived in lunar orbit in late December 2011 and...

Mars Rover ChemCam Sees Patterns In Martian Rocks
2013-03-20 04:44:02

Lee Rannals for redOrbit.com - Your Universe Online Los Alamos National Laboratory postdoctoral researcher Nina Lanza announced at the 44th Annual Lunar and Planetary Science Conference in The Woodlands, Texas that Curiosity's ChemCam laser could be offering some detailed inside information about the Red Planet's surface. NASA's Curiosity rover has a laser-shooting instrument onboard known as the ChemCam, which is used to vaporize a pinpoint of rock surface. The instrument is able to...

The Red Planet May Have Once Been Blue: Curiosity Finds More Evidence Of Water
2013-03-18 15:08:33

Lee Rannals for redOrbit.com — Your Universe Online NASA announced last week about how its Curiosity rover has found evidence for ancient environmental conditions favorable for life, and today a team has expanded on those findings. Scientists said during a news briefing at the Lunar Planetary Science Conference in The Woodlands, Texas about how Curiosity found evidence of water-bearing minerals in rocks near where it found clay minerals inside a drilled rock. Using...

Cassini-Huygens Mission -- The Cassini unmanned space probe is intended to study Saturn and its moons. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004. The mission is a joined NASA/ESA project. Cassini's principal objectives are to: -- determine the three-dimensional structure and dynamical behavior of the rings -- determine the composition of the satellite surfaces and the geological history of each object -- determine the nature and...
