The private spaceflight company SpaceX declared that 2012 would be the "Year of the Dragon" - a play on the current cycle of the Chinese calendar and the upcoming tests of SpaceX's Dragon space capsule. For a time, it seemed as if SpaceX was regretting that slogan. Dragon was chosen as one of five competitors for NASA's Commercial Orbital Transportation Services (COTS) contest to develop a cargo/passenger craft to service the International Space Station. The Dragon program had enjoyed considerable success and was scheduled to be the first private spacecraft to visit and, if all went well, dock with the International Space Station (ISS). Unfortunately, with the need for more testing of the Dragon capsule delaying the launch from its original February 7, 2012 date to late March or even into April, it looked as though the Year of the Dragon was starting a bit late.

Over the course of a year, NASA's Interstellar Boundary Explorer (IBEX) scans the entire sky. During February, its instruments are aligned in the correct direction to intercept atoms that have crossed the boundary from interstellar space into our solar system, become caught by the Sun's gravity and slung around the star. This has now allowed IBEX to capture the most complete glimpse of the material that travels in the galactic wind in the space between star systems. The results indicate this material doesn't look like the same material that makes up our solar system. Read More

SpaceX, the California company that is developing the reusable Dragon spacecraft, recently test-fired its new SuperDraco engine. Presently, the Dragon capsule is equipped with less-advanced Draco engines, which are designed for maneuvering the spacecraft while in orbit and during reentry. The SuperDraco, however, is intended to allow the astronauts to escape if an emergency occurs during the launch. Read More

Last year, NASA announced it was seeking proposals for mission concept studies of a high-power solar electric propulsion (SEP) system that could be used in a "space tugboat." Such a ship would be used ferry payloads in low Earth orbit (LEO) into higher energy orbits, saving on fuel and the use of expensive secondary boosters. NASA also anticipates an SEP system could be used to propel spacecraft into deep space for science missions and for the placement, service, resupply, repositioning and salvaging of space assets by commercial operators.

Russia's 13-ton (11.8-tonne) unmanned Phobos-Grunt interplanetary space probe that was launched from the Baikonur Cosmodrome in Kazakhstan on November 9, 2011 has reportedly burned up in the Earth's atmosphere. According to Russian Air and Space Defence Forces, the spacecraft was destroyed on Sunday, January 15th, 2012 at 1745 GMT as it made an uncontrolled re-entry and broke up 775 miles (1,250 km) west of Chile in the South Pacific.

Nasa’s twin GRAIL (Gravity Recovery And Interior Laboratory) spacecraft are now in orbit around the Moon. Having achieved lunar orbit at 2 pm PST on New Year’s Eve, GRAIL-A was joined by GRAIL-B at 2:43 pm PST on New Year’s Day. The twin spacecraft are now in a near-polar, elliptical orbit with an orbital period of approximately 11.5 hours. In readiness for the science phase of the mission which is due to start in March 2012, both spacecraft will undergo a series of burns to place them in a near-polar, near-circular orbit with an altitude of about 34 miles (55 km) and orbital period of just under two hours.

If all goes to plan, tomorrow at 1:21 p.m. PST, NASA's GRAIL-A spacecraft will enter orbit about the Moon. GRAIL-A is one of two unmanned orbiters launched in September, with its sibling GRAIL-B due to enter orbit the following day (New Year's Day) at 2:05 p.m. PST. Together the two craft constitute the GRAIL mission (Gravity Recovery And Interior Laboratory), charged with mapping the Moon's gravitation field. Read More

Call it Ishmael. Actually, no, call it the Comet Nucleus Sample Return mission spacecraft. Regardless of its name, the NASA vehicle will be wielding a harpoon, not unlike the narrator of Moby Dick. Instead of hunting a white whale, however, it will be after a comet. Although the spacecraft itself is still a concept, its harpoon is in the works now. Read More

Seven years ago, philanthropist Paul G. Allen collaborated with aerospace expert Burt Rutan, to create SpaceShipOne – the first privately-funded, manned rocket ship to fly beyond Earth’s atmosphere, and winner of the Ansari X PRIZE. Now, in the post-Shuttle era, the two men have reunited to create a reusable vehicle for launching both manned and unmanned rockets into space. The project was announced in Seattle today. Read More
