“This is the single most powerful piece of evidence for liquid water at Mars that has been discovered by the Opportunity rover”, said an expert from the Cornell University, Steve Squyres, who is serving as a Principal Investigator of Opportunity, while appearing for an interview with the American Geophysical Union.
The expert made the statement in response to an announcement made by scientists claiming to acknowledge several evidences to show existence of water on Mars, identified by a well-traveled NASA Mars rover, on Wednesday.
Around eight years back, the Opportunity rover had landed successfully on Mars and acknowledged a very thin bright mineral vein along with Endeavour, rim of a huge crater. After analyzing the attributes, the experts have notified that the mineral resembles gypsum in a number of properties.
The Opportunity, a golf-cart-size rover, along with its twin Spirit has succeeded to land on Mars in January 2004, as an attempt to complete its hunt to identify the signs of various water activities occurred during the ancient era, particularly on the planet that has a popular name “Red Planet”.
After completing a three-year trek, the Opportunity entered the 14-mile-wide Endeavour Crater in August and discovered the mineral vein that is believed around 51 centimeters long with identical thickness of a human thumb.
During the last month, the scientists have properly examined the vein with the help of cameras installed in the Opportunity as well as X-ray spectrometer and marked it as a hydrated form of calcium sulfate. Presently, the material is used in the making of drywall and plaster of Paris.
A rover project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, Bruce Banerdt, notified some symptoms of advanced age in the robotic arm joints of Opportunity, identical to shoulder of a person living with arthritics.
