NASA’s Curiosity rover analysis of rock sample reveals Mars at one time could have supported Life

Washington, D.C. – An analysis of a rock sample recently collected by NASA’s Curiosity rover shows ancient Mars could have supported living microbes.

“A fundamental question for this mission is whether Mars could have supported a habitable environment,” said Michael Meyer, lead scientist for NASA’s Mars Exploration Program at the agency’s headquarters in Washington. “From what we know now, the answer is yes.”

These fine-grained sediments, likely deposited under water, suggest that Mars could have supported ancient microbial life. Data gathered by Curiosity indicate a habitable environment characterized by neutral pH, chemical gradients that would have created energy for microbes, and a distinctly low salinity, which would have helped metabolism if microorganisms had ever been present.

NASA’s Mars rover Curiosity Instruments begins to analyze first sample of rock powder on Mars

Pasadena, CA – Two compact laboratories inside NASA’s Mars rover Curiosity have ingested portions of the first sample of rock powder ever collected from the interior of a rock on Mars.

Curiosity science team members will use the laboratories to analyze the rock powder in the coming days and weeks.

The rover’s Chemistry and Mineralogy (CheMin) and Sample Analysis at Mars (SAM) instruments received portions of the sample on Friday and Saturday, February 22nd and 23rd, respectively, and began inspecting the powder.

The left Mast Camera (Mastcam) on NASA’s Mars rover Curiosity took this image of Curiosity’s sample-processing and delivery tool just after the tool delivered a portion of powdered rock into the rover’s Sample Analysis at Mars (SAM) instrument. This Collection and Handling for In-situ Martian Rock Analysis (CHIMRA) tool delivered portions of the first sample ever acquired from the interior of a rock on Mars into both SAM and the rover’s Chemistry and Mineralogy (CheMin) instrument.

Pasadena, CA – NASA’s Mars rover Curiosity has relayed new images that confirm it has successfully obtained the first sample ever collected from the interior of a rock on another planet. No rover has ever drilled into a rock beyond Earth and collected a sample from its interior.

Transfer of the powdered-rock sample into an open scoop was visible for the first time in images received Wednesday at NASA’s Jet Propulsion Laboratory in Pasadena, CA.

NASA’s Mars Curiosity Rover finishes analyzing it’s first Martian Soil Sample

Pasadena, CA – NASA’s Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiosity’s arm delivered to an analytical laboratory inside the rover.

Detection of the substances during this early phase of the mission demonstrates the laboratory’s capability to analyze diverse soil and rock samples over the next two years. Scientists also have been verifying the capabilities of the rover’s instruments.

NASA’s Mars Curiosity Rover completes first analysis of Martian Soil

Pasadena, CA – NASA’s Mars rover Curiosity has completed initial experiments showing the mineralogy of Martian soil is similar to weathered basaltic soils of volcanic origin in Hawaii.

The minerals were identified in the first sample of Martian soil ingested recently by the rover. Curiosity used its Chemistry and Mineralogy instrument (CheMin) to obtain the results, which are filling gaps and adding confidence to earlier estimates of the mineralogical makeup of the dust and fine soil widespread on the Red Planet.

This graphic shows results of the first analysis of Martian soil by the Chemistry and Mineralogy (CheMin) experiment on NASA’s Curiosity rover. The image reveals the presence of crystalline feldspar, pyroxenes and olivine mixed with some amorphous (non-crystalline) material. (Image credit: NASA/JPL-Caltech/Ames)

NASA’s Mars rover Curiosity’s fourth scoop of Martian Soil to be analyzed by Chemistry and Mineralogy (CheMin) instrument this week

Pasadena, CA – NASA’s Mars rover Curiosity shook a scoopful of dusty sand inside its sample-handling mechanism on Sol 75 (October 21st, 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 October 22nd and plans to analyze another sample from the same scoopful with the Chemistry and Mineralogy (CheMin) instrument later this week.

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 (October 20th, 2012).

Pasadena, CA – 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.

Three bite marks left in the Martian ground by the scoop on the robotic arm of NASA’s Mars rover Curiosity are visible in this image taken by the rover’s right Navigation Camera during the mission’s 69th Martian day, or sol (October 15th, 2012). (Image credit: NASA/JPL-Caltech)
