Curiosity Rover Collects Fourth Scoop of Martian Soil

The Chemistry and Camera (ChemCam) instrument on NASA's Mars rover Curiosity used its laser and spectrometers to examine what chemical elements are in a drift of Martian sand during the mission's 74th Martian day, or sol (Oct. 20, 2012). Image Credit: NASA/JPL-Caltech/LANL/CNES/IRAP/LPGN/CNRS.

NASA's Mars rover Curiosity shook a scoopful of dusty sand inside its sample-handling mechanism on Sol 75 (Oct. 21, 2012) as the third scrubbing of interior surfaces of the mechanism.

The rover team is instructing the rover to deliver a sieved sample from this scoopful - the mission's fourth - onto Curiosity's observation tray on Oct. 22 and plans to analyze another sample from the same scoopful with the Chemistry and Mineralogy (CheMin) instrument this week.

Curiosity collected this fourth scoop of soil on Sol 74 (Oct. 20). A later scoop will become the first delivered to the Sample Analysis at Mars (SAM) instrument.

While continuing with scooping activities at the "Rocknest" site, the rover also has been examining surroundings with the Chemistry and Camera (ChemCam) and Mast Camera (Mastcam) instruments, and monitoring environmental conditions with the Radiation Assessment Detector (RAD), Rover Environmental Monitoring Station (REMS) and Dynamic Albedo of Neutrons (DAN) instruments of its science payload.

Sol 75, in Mars local mean solar time at Gale Crater, ended at 8:58 a.m. Oct. 22, PDT (11:58 a.m., EDT).

Mars Soil Sample Delivered for Analysis Inside Rover
Pasadena CA (JPL) Oct 19, 2012
NASA's Mars rover Curiosity has ingested its first solid sample into an analytical instrument inside the rover, a capability at the core of the two-year mission. The rover's Chemistry and Mineralogy (CheMin) instrument is analyzing this sample to determine what minerals it contains. "We are crossing a significant threshold for this mission by using CheMin on its first sample," said C ... read more
