In more bad news for future voyagers to Mars, a team of scientists at the Georgetown University Medical Center (GUMC) has found the kind of Galactic Cosmic Radiation (GCR) that astronauts will encounter on long space voyages can cause heavy damage to their gastrointestinal (GI) tract. read more

Forget steel, forget diamond and even forget everyone’s favorite wonder material graphene – “nuclear pasta” may be the strongest material in the universe. This strange substance is formed in the intense pressures inside neutron stars, and researchers have now run computer simulations to test just how strong it is. read more

China is one step closer to leading the search for alien radio signals. On Sunday the Chinese Academy of Sciences (CAS) announced that the Five-hundred-meter Aperture Spherical radio Telescope (FAST) has begun operations. FAST takes over the title of world’s largest radio telescope from the 305-meter Arecibo Observatory in Puerto Rico. read more

The asteroids that are whizzing around our little corner of space are basically the crumbs left over from the formation of the solar system, and that means they have a lot to tell us about those early years. Now, scientists have studied a particularly weird space rock and found that it’s the oldest known igneous meteorite, dating back to one of the very first volcanic eruptions in the solar system. read more

NASA Gets Voyager 1 Going Again

After almost four decades of dormancy, NASA has successfully ordered the Voyager 1 deep space probe to fire a set of thrusters that have been inactive for 37 years. The November 28 test was carried out by mission control at the Jet Propulsion Laboratory (JPL) in Pasadena, California, as part of an effort to keep the unmanned explorer functional for up to an additional three years as it speeds into interstellar space. read more

Virgin Galactic Powers On

Virgin Galactic’s manned spaceplane has hit another milestone, breaking Mach 2 as it roared into the mesosphere. With test pilots Dave Mackay and Mike “Sooch” Masucci at the controls, VSS Unity was released from the mothership VMS Eve at an altitude of 46,500 ft (14,200 m) before firing its hybrid rocket engine for 42 seconds to power it to 170,800 ft (32.3 mi, 52 km) and a speed of Mach 2.47 (1,832 mph, 2,948 km/h). read more

We’ve long known that Mars is home to the largest volcano in the Solar System – Olympus Mons – and now, researchers have found that it may also have the largest explosive volcanic deposit as well. The Medusae Fossae Formation is a huge rocky structure that has had scientists puzzling over its origins for decades, but the new work suggests it’s the result of massive volcanic eruptions that would have changed the climate of the Red Planet. read more
