The ESA has successfully corrected the orbit of its sixth Galileo satellite following its launch into an elongated orbit in August 2014. It took 14 maneuvers to reposition the probe, which is designed to form part of a new global navigation system on par with existing GPS and Glonass solutions. Read More
A team of astronomers combining radio data from the Green Bank Telescope, West Virginia, and data from the radar transmitter at the National Science Foundation's Arecibo Observatory, Puerto Rico, have compiled a stunning new view of Venus. Often described as Earth's twin due to its similar proportions, capturing high quality images of the inhospitable planet has traditionally been a challenging prospect thanks to extreme atmospheric conditions. However, by combining observations from the instruments to create a more complete picture of Venus, astronomers can begin to observe how this enigmatic celestial object evolves over time. Read More
An international team led by astronomers from Queen's University Belfast has identified the fastest ever star on an escape trajectory from the Milky Way – the white dwarf US708, which is traveling at a staggering 1,200 km per sec (746 miles per sec). The discovery of this star may shed light on the astronomical events that are vital to the calculation of distances in our universe. Read More
Lockheed Martin has provided a glimpse at the next generation of commercial spacecraft by revealing its proposal for NASA's Commercial Resupply Services 2 (CRS-2) program. The new cargo ships, which Lockheed compares to the US transcontinental railroads of the 19th century, are designed to not only resupply the International Space Station, but also support manned deep space missions, such as the first expedition to Mars.

An ultraviolet light show has provided space scientists with the best evidence yet that the Jovian moon Ganymede has a gigantic ocean beneath its icy surface. Images captured by the Hubble Space Telescope of the aurorae in the moon's tenuous atmosphere provide what NASA calls the best evidence yet for a wet Ganymede where life could exist. Read More
A successful ground test of a system designed to ultimately collect solar power from orbit and beam it back down to Earth was announced in Japan this week by Mitsubishi Heavy Industries. The wireless power demonstration saw 10 kilowatts sent over microwaves from a transmitting unit to a receiver 500 meters (1,640 ft) away. Read More
NASA astronaut Barry Wilmore and Roscosmos cosmonauts Alexander Samokutyaev and Elena Serova have safely touched down in Kazakhstan on Mar. 11, with the landing heralding the end of a 167-day mission to the International Space Station. During their time in low-Earth orbit, the crew's activities were planned to the minute by mission controllers on the ground. Over the course of Expedition 42, hundreds of experiments were undertaken relating to the effects of the microgravity environment aboard the station, the potential benefits of which will aid future astronauts, as well as the people back on Earth.

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.

The digital infrared sensor installed on the ESA’s Proba-V satellite is being adapted for use back home. While it’s currently being used to provide fresh pictures of the entirety of Earth’s flora every two days, its creators believe it’s well suited to less exotic applications, such as scanning for skin diseases and spotting defects in production lines.

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.
