The European Space Agency (ESA) has temporarily suspended its attempt to reestablish contact with its Philae lander on Comet 67P/Churyumov-Gerasimenko. For eight days, the agency’s Rosetta probe unsuccessfully beamed a wake up signal to the hibernating lander, which has been silent since its batteries were exhausted in November. Read More
Though the Sierra Nevada Corporation (SNC) Dream Chaser spaceplane was kicked out of the running to ferry crew to the ISS, a variation on the craft may still end up visiting the station. As part of its bid to win NASA’s Commercial Resupply Services 2 (CRS2) contract, SNC has unveiled an unmanned autonomous version of Dream Chaser to carry cargo into orbit. Read More
The ESA is preparing a number of its orbital assets to observe Friday morning's solar eclipse, when the Moon will pass in front of the Sun's disk, blocking the light from our parent star in spectacular fashion. The event will be viewable to most of Europe, however the degree to which the Moon will obscure the Sun will vary depending on location. Viewers in parts of Norway will experience a total eclipse, while those watching from Rome will only see 56 percent of our star's surface covered. Read More
"A sailor must be able to swim in the sea. Likewise, a cosmonaut must be able to swim in outer space." With those words, the head of the Soviet space program, Sergei Korolev, initiated the crew of the first spacewalk mission. On March 18, 1965, cosmonauts Alexei Leonov and Pavel Belyayev lifted off in Voskhod (Sunrise) 2, from which Leonov would exit to become the first person in history to step into the vacuum of space.

New software based on an algorithm developed in an open competition hosted by NASA improves the detection rate of potentially hazardous near-Earth asteroids. The software comes in the form of a free-to-download application, capable of being run from most laptops or desktops, transforming any amateur astronomer into a seasoned asteroid hunter. Read More
Most missions to the International Space Station range from 160 to 180 days, but this month Russia and NASA will launch a joint year-long mission designed to more fully test the stress of space travel on the human body. ISS veterans Scott Kelly (US) and Mikhail Kornienko (Russia) have been training for two years for this daunting mission, culminating in departure slated for March 27, 2015, 3:42 p.m. EST. from the historic Baikonur Cosmodrome.

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.
