SpaceShipTwo makes a spectacle of itself in “Cold Flow” test
Just a week after the first in-flight venting of its nitrous system, Virgin Galactic’s SpaceShipTwo has made an even more spectacular step on the way to its first powered flight. The craft's 25th glide flight on April 12 saw oxidizer flow through the craft’s propulsion system and expelled through the nozzle at its rear in what is known as a “Cold Flow” procedure. Read More
Russian space enthusiasts have pinpointed the resting place of what is believed to be the Soviet lander, Mars 3, which failed shortly after landing in 1971. Using images returned by NASA's Mars Reconnaissance Orbiter, a crowdsourcing effort has found what may be four components of the lander, its parachute and descent module. Read More
Boeing announced on Friday that the preliminary design review for the Launch Vehicle Adapter (LVA) for the Crew Space Transportation (CST)-100 spacecraft has been successfully completed. This is the third milestone completed by Boeing under NASA’s Commercial Crew Integrated Capability (CCiCap) agreement, the purpose of which is to develop a privately owned and operated U.S. replacement for the Space Shuttle to ferry crew to and from the International Space Station (ISS).

Virgin Galactic's SpaceShipTwo left terra firma for her 24th glide flight on Wednesday morning. The flight was the first in which the loading and venting of the ship's nitrous system was tested. Virgin Galactic described the flight as "another key milestone on the way to our first powered flight." Read More
This month, the University of Helsinki and the European Space Agency (ESA) will test a new space tether that has less chance of snapping under the stresses of operating in orbit. Installed aboard Estonia’s ESTCube-1 cubesat, the new tether is scheduled to be launched with ESA’s Proba-V satellite atop a Vega rocket as part of an experiment in developing an electric solar sail.

A manned Soyuz spacecraft set a record for traveling to the International Space Station (ISS), arriving six hours after launch instead of the usual two days. Soyuz 34 lifted off from Baikonur Cosmodrome in Kazakhstan on Friday, March 28 at 4:43 p.m. EDT (08:43 GMT) and docked with the ISS at 10: 28 PM EDT (03:28 GMT). It was able to catch up and match trajectories with the ISS in only four orbits using new techniques previously tested in ISS rendezvouses with Russian unmanned Progress cargo ships. Read More
Sun will cause pause in Mars exploration in April
NASA is taking an enforced holiday of sorts in April as it suspends Mars exploration missions for 17 to 21 days. This isn't due to budget cuts, but rather because Mars will be in conjunction with the Sun during April, which will make direct communications with the probes difficult, if not impossible. Read More
Has Voyager 1 left the Solar System? Is it officially the first spacecraft to reach interstellar space? It depends on whom you ask. NASA says no, but W.R. Webber of the New Mexico State University Department of Astronomy and F.B. McDonald of the University of Maryland Institute of Physical Science and Technology say yes. They contend that the unmanned, nuclear-powered probe left the Solar System on August 25, 2012 at a distance of 121.7 AU (18.2 billion km) from the Sun when its instruments on board detected a major shift in cosmic ray intensity.

NASA has released images and findings from the Lunar Reconnaissance Orbiter (LRO), which witnessed the impact of NASA's twin GRAIL (Gravity Recovery And Interior Laboratory) spacecraft as they struck the Moon near the North Pole in a controlled impact on Dec.17, 2012. The unmanned orbiter sent back before and after images of the impact sites and used its Lyman-Alpha Mapping Project (LAMP) instrument to study the plume of dust and gas thrown up by the double impact, producing new insights into the processes going on in the interior of the Moon.

It's been about 10 months since DARPA announced it had awarded seed funding to form an independent, non-governmental organization with the goal of pursuing human interstellar space flight within the next 100 years. Leaders from this "100 Year Starship" effort took to the stage recently at the South By Southwest Interactive festival in Austin, Texas to talk a bit more about what it means to pursue such a "grand challenge."
