Curiosty in the News

Curiosity Tracks Sunspots: Curiosity is monitoring sunspots on the side of the sun facing away from Earth, during weeks when sun-monitoring spacecraft can't provide that information.
Curiosity Studies Rock-Layer Contact Zone: At the rover's current location near "Marias Pass" on Mount Sharp, Curiosity has found a zone where different types of bedrock neighbor each other. One is pale mudstone, like bedrock the mission examined previously at "Pahump Hills." Another is the "Stimson unit" a darker, finely bedded sandstone above the Pahrump-like mudstone.
Mars Conjunction: The teams running NASA's three active Mars orbiters and two Mars rovers will refrain from sending commands to their spacecraft from about June 7 to June 21, 2015. During that period, the sun will be within two degrees of Mars in Earth's sky and radio communications with the orbiters and rovers will be impaired.
Curiosity's Laser-zapping Instrument Gets Sharper Vision: Tests have confirmed success of a repair to the autonomous focusing capability of the Chemistry and Camera (ChemCam) instrument on Curiosity. This instrument provides information about the chemical composition of targets by zapping them with laser pulses and taking spectrometer readings of the induced sparks.

Curiosity Gets More Looks at its Surroundings; Health Checks Continue: Curiosity is healthy as it continues to familiarize itself with its new home in Gale Crater and check out its systems. The team's plans for Curiosity checkout today included raising the rover's mast and continued testing of its high-gain antenna, whose pointing toward Earth will be adjusted on Sol 2.
Curiosity Safely on Mars! Health Checks Begin : On its first Martian day, designated Sol 0, the rover is checking its health and measuring its tilt. All Sol 0 spacecraft activities appear to have been completely nominal.
Curiosity Has Landed!: NASA's most advanced Mars rover Curiosity has landed on the Red Planet. The one-ton rover, hanging by ropes from a rocket backpack, touched down Aug. 6th at 1:32 AM EST ending a 36-week flight and beginning a two-year investigation. The Mars Science Laboratory spacecraft that carried Curiosity succeeded in every step of the most complex landing ever attempted on Mars, including the final severing of the bridle cords and flyaway maneuver of the rocket backpack.
Curiosity Readies For Dramatic Entrance: An enormous robot is about to hit the red dirt of Mars - not too hard, NASA hopes - in search of life-friendly environments, or remnants of them. The Curiosity roverís off-road adventures will begin only if it survives a daring seven-minute, 125-kilometer plunge through the planetís carbon dioxide atmosphere.
NASA's Car-Sized Rover Nears Daring Landing On Mars: NASA's most advanced planetary rover is on a precise course for an early August landing beside a Martian mountain to begin two years of unprecedented scientific detective work. However, getting the Curiosity rover to the surface of Mars will not be easy. The Curiosity landing is the hardest NASA mission ever attempted in the history of robotic planetary exploration.
