Water Flows On Mars, Say Experts

“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.

NASA Claims To Have Identified a New Planet, Kepler-22b

“This discovery shows that we Homo sapiens are straining our reach into the universe to find planets that remind us of home. We are almost there”, said an expert from the University of California, Geoff Marcy, in an email while briefing about the discovery of a latest planet that resembles earth. In addition, the expert has also tagged it as a phenomenal discovery up till now in history.

Further, the experts have notified that the newly identified planet that has reflected all feasible conditions to support life is located outside the solar system. According to astronomers, the planet is smack in the middle of the Goldilocks zone, a difficult location to be acknowledged easily, although, possessing feasible environmental for life conditions that are not cold or hot, extremely. Scientists have notified that it has 72 degrees temperature, identical to the surface of a shopping mall.

On Monday, the NASA officials have confirmed the discovery of new planet along with other discoveries such as Kepler telescope. The high potential telescope was launched during the planet-hunting mission, observed in 2009.

This is for the first time, when scientists have acknowledged any planet in the inhabitable zone for Kepler. The new planet is named as Kepler-22b and possess some similar features that of earth, although, circles a star identical to sun along with same distance, approximately. Besides environmental conditions, it is believed to have one year of 290 days, very close to the year of earth.

The Kepler Deputy Science Chief, Natalie Batalha, notified that the planet has also displayed some tough conditions such as its size and notified that it is approximately 2.4 times more as compared to the size of earth. Further, the expert has anticipated possibilities that it can support an environment like gas-and-liquid Neptune.
