NASA wants the industry's ideas for deep space habitats
NASA announced on Thursday that it is seeking development proposals for deep space habitats -- the kind that astronauts will call home on trips to Mars and beyond. This call is the second part of NASA's public-private partnership, Next Space Technologies for Exploration Partnerships (NextSTEP), which requested initial concept proposals last October.
NASA's MESSENGER begins orbit around Mercury, will start beaming back science early next month
Mercury, the innermost planet of our humble little solar system, is getting itself an orbital friend. The MESSENGER space probe (known as MErcury Surface, Space ENvironment, GEochemistry and Ranging to his nearest and dearest) is concluding a six-year sojourn through the dark void of space with an elliptical orbit around the tiny and otherwise inhospitable planet. Systems are about to get turned on and fully checked next week, before the data-gathering phase kicks off in earnest on April 4th. Science, isn't it beautiful?
IKAROS gets first burst of solar propulsion, wants more
Photons, man, it's all about the photons. Japan's solar sail-equipped IKAROS probe has recorded its first propulsion derived from the force of sunlight rays hitting its tender surface. The force generated is a truly minuscule 1.12 millinewtons, but that can go a long way (literally) in a frictionless environment like space. The kite's sails also soak up Sol's emitted light to generate electricity, making the most out of the one resource available to it. So now that we've figured out how to do all that, shall we get started on colonizing Mars or what?
IKAROS successfully stretches wings, prepares for solar spaceflight
Though it may look like a collection of tinfoil and string, the photo above depicts what may be the first solar sail to actually propel a spacecraft. Japan's IKAROS (Interplanetary Kite-Craft Accelerated by Radiation of the Sun) just unfurled the 7.5 micron (.0003-inch) thick polyimide membrane 7.4 million kilometers from Earth this week, and expect its embedded thin-film solar panels to propel the craft past Venus and towards the dark side of the sun. Because wax and feathers only get you so far.
Ion propulsion engine could take you to Mars in 39 days
Ready for some interplanetary exploration? We've had the force shields, currency, and refuel stations all sorted out for a while, and now here come the ion thrusters we've been missing to make manned trips to Mars really viable. Currently, a return journey to Mars can take up to two years, with crew members having to wait a full year for the planets to realign, but with ion propulsion -- which uses electricity to accelerate ions and produce small but longevous thrust -- ships can get there within a reasonably tight 39-day window. Ion propulsion rocket engines were first deployed successfully by NASA in the Deep Space 1 probe in 1998, and the latest iteration's successful Earth-bound testing has led to plans for a flight to the moon and use on the International Space Station as test scenarios for the technology. It's all still very much in the early stages, of course, but should all that testing, checking, and refinement bear fruit, we might finally have a whole new world to colonize and sell sneakers on.

Interplanetary internet proposed by Jet Propulsion Laboratory engineer
We'll admit, we were admittedly metagrabolised after hearing that the US military wanted to launch a router into space, but now clarity is upon us. According to Vinton Cerf and a team of diligent engineers at the California-based Jet Propulsion Laboratory, standards for space communications could be established in just three short years, meaning that an "interplanetary internet" could be just around the bend. Cerf reckons that such a system would allow Earthlings to "access information and to control experiments taking place far away" from our planet, and in the distant future, there could even be an "interplanetary backbone [erected] to assist robotic and manned missions with robust communication." And while there's no mention of setting up galactic ISPs, we're pretty certain that lonely Martians would pay a pretty penny for quasi-reliable broadband access.[Via TGDaily]
