Astronomers have disproved the existence of two exoplanets thought to orbit Gliese 581 in ...

Those packing their bags for a trip to the two potentially habitable exoplanets previously claimed to be orbiting the red dwarf star Gliese 581 had better rethink their travel plans. Astronomers at Pennsylvania State University say the planets, Gliese 581 d and Gliese 581 g, don't actually exist.  Read More

The ESA has tested a novel system that may allow the agency to safely land rovers on Mars using a quadcopter-like dropship. A fully automated, proof of concept Skycrane prototype was created over the course of eight months under the ESA's StarTiger program, with the system's hardware largely derived from commercially available quadcopter components.  Read More

As the US prepares for 4th of July fireworks here on Earth, a nearby spiral galaxy similar to our Milky Way is putting on a pyrotechnics display of its own. The galaxy, NGC 4258 (also known as Messier 106 or M 106), is ejecting gas and high-energy particles in a spectacular display of power that is rippling across the face of the galaxy with shock waves of stellar energy.  Read More

Picture taken from Cassini in 2013, displaying the Earth as seen from orbit around Saturn ...

Having returned a vast number of incredible images of Saturn, her rings and her moons, NASA's Cassini spacecraft is reaching the final stage of its marathon mission. As such, and with the help of over 2,000 members of the general public, mission operators have selected a fitting name for the final maneuvers of the iconic spacecraft.  Read More

NASA has successfully carried out the first of three airborne tests for its Low-Density Supersonic Decelerator (LDSD), a saucer shaped test vehicle which will one day be used to slow down scientific payloads entering the atmosphere of Mars. This new system of atmospheric deceleration will allow the agency to contemplate heavier, more ambitious endeavors, building towards a manned mission to the red planet.  Read More

Given that there isn't any gravity on the International Space Station you’d think that shoes would be a very low priority, but on the latest Russian Soyuz capsule to dock with the station, NASA sent along a pair of high-tech ForceShoes to monitor astronauts as they exercise to make sure they get the full benefits of their workouts.  Read More

A mock Orion spacecraft falls to Earth under three fully deployed main parachutes (Photo: ...

NASA has upped the ante in its most recent test of the Orion spacecraft's parachute deployment system ahead of its maiden test flight (EFT-1) scheduled for launch later this year. Today's operation saw a test version of the Orion crew module falling through the skies above Arizona on the 14th of 17 planned drops designed to test a soft landing system which may one day protect astronauts returning from missions to Mars.  Read More

An Arizona-based company is planning to offer commercial subspace balloon flights by 2016 ...

Arizona-based World View Enterprises has successfully completed its first test flight of a space tourism balloon that, for the price of US$75,000 per person, will lift six passengers into the stratosphere to an altitude of 20 miles (32 km). From there, they will be able to see the curvature of the Earth. The company says it is on track to fly its first passenger in just two years time.  Read More

Artist's concept of a derelict satellite being reeled in after being harpooned by the e.De...

In 2021, as part of its Clean Space Initiative, ESA plans to launch the e.DeOrbit mission. The aim of this mission is to clean up the important polar orbits between altitudes of 800 to 1,000 km (500 to 625 mil) that face the prospect of becoming unusable due to the increasing buildup of space debris. The ESA has now announced plans to examine the potential for the mission to use space harpoons to capture large items, such as derelict satellites and the upper stages of rockets.  Read More

Falcon 9 on the launch pad

SpaceX today aborted the launch of a Falcon 9 rocket carrying six Orbcomm OG2 communication satellites; the second mission flight of a Falcon booster equipped with landing legs. Six minutes and nine seconds before the lift off, mission control declared the abort due to a problem with the second stage of the rocket.  Read More
