NASA to Send Million-Year-Old Rock Back To Mars

NASA to Send Million-Year-Old Rock Back To Mars

Textured rows on the ground in this portion of "Perseverance Valley" are under investigation by NASA's Mars Exploration Rover Opportunity, which used its Navigation Camera to take the component images of this downhill-looking scene. As per the latest information, the rover is now working good and NASA is expected that it will contribute more to Mars exploration mission by revealing some interesting facts about Mars in future. Geologists believe the meteor originated from Mars, and NASA now plans to send it back, but with a objective: to serve as a control sample for research to be conducted on similar Martian formations.

Earth has a limited supply of Martian meteorites, which scientists determined were blasted off Mars' surface millions of years ago. More than 14 years later, she's still going strong, and as we reported recently just achieved its 5,000th sol on February 17. (In second place is the Soviet Union's remote-controlled Lunokhod 2 rover, which traveled about 24.4 miles, or 39 km, on the moon back in 1973.) The rover has beamed about 225,000 images home to Earth during its time on the Red Planet, mission officials said.

Space agencies around the world have sent their own rovers equipped with advanced instruments like NASA's Pathfinder mission carried Sojourner in 1997 however, it broke down it just 3 months after being deployed. It's mysterious. It's exciting. If the planet's obliquity were to change enough, water now frozen at the poles could vaporize into the atmosphere and turn to snow or frost closer to the equator, NASA said.

"Perseverance Valley is a special place, like having a new mission again after all these years".




Stone stripes are very distinctive characteristics in rocks which were formed on Earth upon the freezing and thawing of the soil in repeated cycles.

The channel descending a Martian slope in this perspective view is "Perseverance Valley", the study area of NASA's Mars rover Opportunity as the rover passes its 5,000th Martian day. "I think the set of observations we'll get will enable us to understand it".

On some slopes within the valley, the soil and gravel particles appear to have become organized into narrow rows or corrugations, parallel to the slope, alternating between rows with more gravel and rows with less. Well, the scientists have not detected the origin of the whole valley yet. But it has outlived and has been there in space for more than 4900 Martian or sol days and the rover continues to make great discoveries. They are also considering a range of possible explanations for the stripes, and remain uncertain about whether this texture results from processes of relatively modern Mars or a much older Mars.

On the other hand, researchers have previously observed that Mars is tilting once every several hundreds of thousands of years.
