Martians getting curious - NASAs Curiosity rover has been on Mars now for 3-years


#NASA #CuriosityRover #Mars NASA's Mars rover Curiosity had landed on the Red Planet Mars on 5 August 2012 and, has now been an integral part of the Martian landscape – that must have caused furrows on the foreheads of Martians up there. Anyway, Curiosity has trundled across the Red Planet for three very productive and eventful years and has sent back useful information.
This has been reported in space.com dated 5 August 2015.
The six-wheeled robot named Curiosity had a dramatic and unprecedented touchdown on the Martian surface with the aid of a rocket-powered "sky crane" that lowered the 1-ton rover gently by using cables. And, once on ground, the robot set out on its mission of whether its immediate environs — a 96-mile-wide (154 kilometers) crater named Gale — could ever have supported microbial life.
Based on the initial findings, scientists concluded that Gale Crater could have supported a potentially habitable lake-and-stream or water system for long stretches of time — perhaps for millions of years at a time.
The progress has been slow and NASA has to keep requesting for more and more time to carry on its investigations – Curiosity is, after all, a robot and it has to be guided on occasions to perform intriguing tasks that had not been visualized earlier.
Anyway, the man-and-machine team is carrying out work for the future of mankind and needs to get full support and cooperation from all quarters.

NASAs Curiosity rover finds a 96-mile-wide crater, possibly a dried up lake, on Mars


NASAs Curiosity is on track to solve the mystery of whether Mars, the Red Planet, ever had water on it. Hence, its latest find of a huge 96-mile (154-Km) wide crater tends to lend credence to the theory that Mars indeed had water, plenty of it, in the form of lakes.
Scientists have discovered stacks of rocks that contain sediments that appear to have been deposited by water and these are inclined toward the center of the crater – this now reveals a three-mile (5 km) mound called Mount Sharp. Therefore, it is quite possible that Mount Sharp was not there during a period of time roughly 3.5 billion years ago when the crater was filled with water.
Of course, researchers are baffled as to why Mount Sharp that stands about 3 miles (5 kilometers) tall with its lower flanks exposing hundreds of rock layers, sits in a crater.
From these latest findings, a conclusion can be drawn that billions of years ago, a lake once filled this huge crater and as NASA’s Mars rover Curiosity continues to dig up new data, they bolster the thinking that the Red planet was most like the Earth in the solar system and was suitable for microbial life.
These new findings combine more than two years of data collected by the rover since its sky-crane landing inside Gale Crater in August 2012. NAA has plans to send humans to Mars by 2030 and results of such studies could throw up probable areas that would need to be focused upon.
