Summary:
The NASA Mars Science Laboratory Project's rover, Curiosity, will carry a newly delivered laser instrument named ChemCam to reveal what elements are present in rocks and soils on Mars up to 7 meters (23 feet) away from the rover.

The ChemCam instrument for NASA's Mars Science Laboratory mission uses a pulsed laser beam to vaporize a pinhead-size target, producing a flash of light from the ionized material -- plasma -- that can be analyzed to identify chemical elements in the target.

The NASA Mars Science Laboratory Project's rover, Curiosity, will carry a newly delivered laser instrument named ChemCam to reveal what elements are present in rocks and soils on Mars up to 7 meters (23 feet) away from the rover.

The laser zaps a pinhead-sized area on the target, vaporizing it. A spectral analyzer then examines the flash of light produced to identify what elements are present.

The completed and tested instrument has been shipped to JPL from Los Alamos for installation onto the Curiosity rover at JPL.

ChemCam was conceived, designed and built by a U.S.-French team led by Los Alamos National Laboratory, Los Alamos, N.M.; NASA's Jet Propulsion Laboratory, Pasadena, Calif.; the Centre National d'ษtudes Spatiales (the French national space agency); and the Centre d'ษtude Spatiale des Rayonnements at the Observatoire Midi-Pyr้n้es, Toulouse, France.

Nasa Gives You An Excuse to Post a Selfie on Earth Day

TheStreet (Apr. 22, 2014) — NASA is inviting all social media users to take a selfie of themselves alongside nature and to post it to Twitter, Facebook, Flickr, Instagram, or Google Plus with the hashtag #globalselfie. NASA's goal is to crowd-source a collection of snapshots of the earth, ground-up, that will be used to create one "unique mosaic of the Blue Marble." This image will be available to all in May. Since this is probably one of the few times posting a selfie to Twitter won't be embarrassing, we suggest you give it a go for a good cause. Video provided by TheStreet
