Mars may have had more water than the Arctic Ocean

By - March 9, 2015 2 Pictures
In Edgar Rice Burroughs's Barsoom novels, Earthman John Carter's adventures took place on the dry beds of Mar's ancient oceans. Now NASA scientist's say that may not be so far fetched. Though they haven't found signs of any thoats, they have estimated that Mars may once have had enough water to form a vast ocean surrounding its north pole of which only plains remain. Read More

NASA seeks to understand vision changes due to microgravity

By - March 6, 2015 2 Pictures
Having evolved under the pressure of Earth's gravity, it isn't surprising that our bodies experience adverse physiological affects after long periods in low-Earth orbit. NASA hopes that a new experiment, the Fluid Shifts investigation, set to launch to the ISS later this year, will shed light on the causes of vision loss and deformation of the structure to the eye often suffered by astronauts over the course of a stay aboard the ISS.

NASA's Dawn spacecraft added another trophy today to the conquest of space as it went into orbit around Ceres. According to the space agency, the unmanned probe arrived at about 4:39 am PST and is currently circling the dwarf planet at an altitude of about 38,000 miles (61,000 km) – making it not only the first spacecraft to reach a dwarf planet, but also the first to orbit two extraterrestrial bodies.

NASA releases new Ceres images prior to Friday encounter

By - March 3, 2015 5 Pictures
As NASA’s Dawn spacecraft makes its final approach to Ceres, the ion-propelled spacecraft is sending the best images yet with more details about the surface of the dwarf planet. The images from Dawn have shown the presence of numerous craters and unusual bright spots that scientist hope will provide clues as to not only how Ceres formed and if it is still active, but the early history of the Solar System as well.

NASA aims to unlock mysteries of celestial giants by observing rare black hole

By - March 2, 2015 2 Pictures
Ever since they were theorized by Albert Einstein's theory of general relativity back in 1915, black holes have captured the imagination and curiosity of the public and scientists alike. However, despite this popularity, relatively little is known about how these all-consuming giants evolve and shape the environment around them. NASA scientists are hoping to unravel some of these mysteries by observing an intermediate-mass black hole (IMBH) sitting 100 million light years away in the spiral arm of galaxy NGC 2276. Read More

ESA offers CubeSats a deep space ride on asteroid mission

By - February 28, 2015 4 Pictures
CubeSats offer a way to get into space on the cheap. They're compact, inexpensive, and they can piggyback on larger launch payloads to get into orbit. The trouble is, this piggybacking is often like trying to hitchhike cross country on a ride that only goes to the edge of town. The European Space Agency is widening the scope a little by opening a competition for CubeSats to ride into deep space on its Asteroid Impact Mission (AIM). Read More

NASA's colossal crawlers mark half a century of service

By - February 28, 2015 3 Pictures
Two veterans of the US space program have marked 50 years of service with in appropriately sedate style. In 1965, a pair of gigantic crawlers were built to move the Saturn V moon rockets to the launch pad. Half a century later, they are still in service and being upgraded to handle NASA's Space Launch System (SLS) and other launch vehicles. To celebrate, the 6 million lb (2.7 million kg) Crawler-Transporter 2 (CT-2) made a rollout for a visitor and media day at less than one mph. Read More
