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.
