A private company based in Colorado in the United States, and backed by former NASA engineers, has said it intends to fly a manned space mission by the year 2020. The company said it could send lunar missions at a fraction of the cost of government-run operations. It intends to send two people to the Moon for 1.4 billion dollars. Golden Spike Company said it will use existing rocket and capsule technology, and will aim for a first launch before the end of the decade.
Scientists have discovered that the most likely source of water on Moon is the constant stream of charged particles from the Sun known as the solar wind.
The findings by researchers from the University of Michigan imply that ice inside permanently shadowed polar craters on the Moon, sometimes called cold traps, could contain hydrogen atoms ultimately derived from the solar wind.
Theoretical models of lunar water stability dating to the late 1970s suggest that hydrogen ions (protons) from the solar wind can combine with oxygen on the Moon's surface to form water and related compounds called hydroxyls.

On Monday, the rover relayed the first voice recording to be sent from another planet, and on today it will broadcast a song from an artist. But alongside these show pieces, Curiosity - also known as the Mars Science Laboratory - is already warming up its instruments for a science mission of unprecedented scope on the Red Planet.
Nasa said that the rover was already returning more data from Mars than all of the agency's earlier rovers combined. It will eventually trundle to the base of Mount Sharp, the 5 km-high peak at the centre of Gale Crater, in which the rover touched down just over three weeks ago.

But, NASA and photography experts insist they are nothing more than blemishes on the images, picked up by the camera lens sitting on the rover at a distance of 350 million miles away.
NASA has not commented on any of the strange sightings so far.
YouTube user StephenHannardADGUK, part of a group called Alien Disclosure UK, spotted the anomalies on the NASA images. He applied a series of filters to try to shed light on the mystery of the images which are publicly available on the space agency's website.
Whereas, video analyst Marc Dantonio, who has worked on projects for the US government, said that these are simply 'dead pixels' in the image - a regular problem in the world of graphics.
Curiosity, a six-wheeled vehicle the size of a compact car, landed inside a vast, ancient impact crater near Mars' equator on August 6 after an eight-month, 570-million-Km voyage through space.

NASA's Curiosity rover on Mars will undergo a brain transplant over the weekend with a software upgrade to prepare for new tasks ahead. According to NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, the upgrade will take place as part of a series of steps to prepare the rover for its future talks such as driving and using its strong robotic arm.
The process is expected to last roughly four days.
During this time, all other activities, including science, will temporarily be put on hold. The JPL said while Curiosity was completing the software transition, the mission's science team was continuing to analyse images the rover has taken of its surroundings inside Gale Crater.
Curiosity will also use a drill and scoop(खोखला करना), which are located at the end of its robotic arm, to gather soil and powered samples of rock interiors, then sieve(examine in order to test suitability) and parcel out these samples into the rover's analytical laboratory instruments in an attempt to find out signs of life whether in the past or at present.

US space agency NASA has successfully landed a huge new robot Rover on Mars. The one-tonne vehicle, known as Curiosity, touched down in a deep crater near the planet's equator after a plunging through the atmosphere.
It is going to look for evidence that Mars could once have supported life. A signal confirming the Rover was on the ground safely, was relayed to Earth via Nasa's Odyssey satellite, which is in orbit around the Red Planet.
The successful landing of the $2.5 billion Mars Rover was greeted with a roar of approval at mission control at the Jet Propulsion Laboratory in Pasadena, California. Engineers and scientists, who have worked on this project for the best part of 10 years, punched the air and hugged each other.
The mission team will now spend the next few hours assessing the health of the vehicle, also referred to as the Mars Science Laboratory, MSL. An attempt will also be made to retrieve some images of the landing location.

NASA says Greenland's massive ice sheet has melted this month over an usually large area. Scientists said the unprecedented melting took place over a larger area that ever detected in three decades of satellite observation. Melting even occurred at Greenland's coldest and highest place--- Summit station.
The thawed ice area jumped from 40 per cent of the ice sheet to 97 per cent in just four days from July 8. Although about half of Greenland's ice sheet normally melts over the summer months, the speed and scale of this year's melting surprised scientists, who described the phenomenon as extraordinary.
