Saturnian moon may have deep-ocean vents that harbor life

By - March 13, 2015 6 Pictures
In science, it's often the case that solving one mystery just raises more questions. Take Saturn's moon Enceladus. For almost a decade, scientists have been puzzled by the gossamer plumes that waft up from its surface. Data from NASA's Cassini spacecraft now indicates that these may might be due to present-day hydrothermal activity in the vast ocean beneath the crust of the frozen moon, raising the possibility that Enceladus may harbor life.

NASA tests parachute-like space brakes to de-orbit satellites

By - March 11, 2015 7 Pictures
Getting to Earth from the International Space Station (ISS) by jumping out of an airlock with a parachute may seem daft, but a group of students are trying just that with a CubeSat. According to NASA, TechEdSat-4, which was jettisoned from the space station on March 3, has reached its designated orbit, where it will use a parachute-like "exo-brake" to slow it down enough to safely re-enter the Earth's atmosphere.

NASA has successfully completed the first of two tests designed to certify the massive solid fuel boosters which will form a part of NASA's next generation Space Launch System (SLS). Once completed, SLS will represent the most powerful launch vehicle ever constructed and will be responsible for, among other tasks, launching NASA's Orion spacecraft on humanity's first manned mission to Mars.

Researchers theorize two mechanisms that prevent prolific star creation in galaxy clusters

By - March 11, 2015 1 Picture
For a long time, scientists have been searching for an answer as to how galaxy clusters regulate the number of stars they create. Given that the amount of interstellar gas used to create the stellar giants exists in such abundance, this theoretically allows for the creation of many times the current number of stars. A team of researchers from MIT, Columbia University and Michigan State University believe they have found the answer. Read More

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.

Dawn orbits dwarf planet Ceres

By - March 6, 2015 5 Pictures
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.

Curiosity suffers short circuit

By - March 4, 2015 1 Picture
NASA is putting its Curiosity Mars rover on hold for a few days as engineers try to determine the cause and severity of a recent short circuit. The space agency says that during a recent sample-taking operation, the unmanned explorer suffered a transient short circuit that activated an automatic shutdown by the rover's computers. Read More
