Japan's space agency considers using rockets with artificial intelligence
The keyword here is obviously "considers," but it looks like Japan's space agency, JAXA, is indeed seriously thinking about using artificial intelligence to improve their rocket launches. As JAXA scientist Yasuhiro Morita explains, as opposed to simply being "automatic" as rockets are today, an "artificially intelligent" rocket would be able to keep watch on its condition, determine the cause of any malfunction, and potentially even fix it itself. According to JAXA, that would not only make rocket launches more efficient, but more cost-effective as well given the reduced manpower needs. That's not the only new measure being explored to cut costs, though -- as Space.com reports, JAXA's new Epsilon launch vehicle is also being built using fewer, but more advanced components, which promises to let it be moved to the launch pad nearly fully assembled. It's currently set to launch sometime in 2013, although it's not yet clear how much it will actually be relying on AI if such a system is put in place.
Japan sends a ribbon into space, asks it to test the magnetic currents
Tether propulsion seems to be the OLED of the spacefaring world, carrying as it does a lot of promise but seemingly never ready for the big time. The fundamental premise is as simple as it is appealing -- a long strip of metal stretched out in space can theoretically exploit the Earth's magnetic field to maneuver itself without expending any fuel of its own. This is done by sucking up ionospheric electrons at one end and, predictably enough, spitting them out at the other, allowing current to flow through the tether. Japan's aerospace agency has recently shot off a testing vehicle for just this theory, a 300 meter-long, 2.5cm-wide ribbon, which has managed to successfully generate a current. No thrust-measuring equipment was on board and it's still very early days, but hey, there's at least the chance that one day satellites will all sprout long, elegant tails to power their way through the sky... and into our private lives.
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?
Japan's Hayabusa spacecraft returns to Earth after asteroid visit (video)
Japan's plans for sending robots to the moon may still have to wait another decade or so, but the country's space program can now claim another pretty huge victory -- its Hayabusa spacecraft successfully returned to Earth on Sunday after visiting an asteroid to collect samples. That end to the spacecraft's seven-year mission occurred somewhere in the Australian outback and, as you can see above and in the video after the break, it was quite a sight to behold. Despite appearances, however, the breaking up of the spacecraft was actually part of the plan, and Hayabusa's main return capsule is said to have made it to Earth intact -- although it's still not clear if the capsule actually contains any samples of the asteroid. Scientists should know what they have on their hands soon enough, though -- the space agency says it expects to retrieve the capsule sometime on Monday.
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.
Japan sending humanoid robot to the moon by 2015
As the US prepares to send NASA's humanoid Robonaut2 up to the International Space Station in September, Japan's private SOHLA (Space Oriented Higashiosaka Leading Association) is gearing up to send its own two-legged robot to the moon by 2015. The $10.5 million robot named "Maido-kun" is being developed in coordination with the Space Exploration Agency of Japan (JAXA), an organization that has been trying to send robots to the moon since at least 2006. Oh sure, there's little reason to send a wobbling two-legged robotic rover to the crater-pocked face of the moon when four-on-the-floor would be much more practical -- other than it's awesome.
Full Earthrise over the moon captured from space in HD
Late last year, we sat in awe peeping the pictures of Earth captured by the KAGUYA satellite, but we're fairly certain we've spotted Engadget HQ in the latest grabs. All kidding aside, the latest HD Earthrise movie is even more desirable than the last due to this one being a "full" Earthrise, and the Japan Aerospace Exploration Agency isn't hesitating to pat itself on the back for snagging such an accomplishment. Check out the read link for more pictures, video and an explanation of how the whole thing went down.
Japan launches Kizuna satellite, hopes it will deliver high-speed internet
Granted, most of us here in America would turn our noses up at receiving in-home broadband via satellite -- after all, cable and DSL seem to be treating most of us quite alright -- but Japan is hoping to provide access to more regions in Asia-Pacific with its recently launched Kizuna. The experimental satellite is not yet intended for commercial use, but if all goes well, it will enable data transmissions "of up to 1.2 gigabytes per second" at a low cost across Japan and 19 other locales in Southeast Asia. Unfortunately, we've no idea when it will escape the bondage of testing and actually be put to good use, but at least Japan's well on its way to actually establishing that wireless island, eh?[Via CNN, thanks to everyone who sent this in]
Japan's space agency planning space-based solar power arrays
We've seen some pretty out there solar installations, but JAXA, the Japanese space agency, is about to get really far out with its latest project: a space-based solar array that beams power back to Earth. The agency is set to begin testing on the microwave power transmission system on February 20th, with an attempt to beam enough power over the 2.4GHz band to power a household heater at 50 meters (164 feet). That's certainly not the sort of large-scale sci-fi power system we were hoping for, but fret not -- if the tests are successful, JAXA's plan is to eventually launch a constellation of solar satellites, each beaming power to a 1.8-mile wide receiving station that'll produce 1 gigawatt of electricity and power 500,000 homes.
KAGUYA satellite captures HD Earthrise
The Japan Aerospace Exploration Agency's (JAXA) KAGUYA satellite that we talked about before has now turned its HDTV eye back towards the big blue marble that is Earth. The HD eye in the sky has recast one of the most famous photos ever, the "Earthrise" captured during the Apollo 8 mission in 1968. If you liked the initial footage from this satellite, you know the drill: click the read link to check out HD still frames and ED-like 480 x 720-pixel versions of the HD "Earthrise" and "Earthset" captures. Okay, JAXA, we'll accept the missing audio track, but make with the full-HD movies of this footage![Via spaceref.com]
Japanese scientists make breakthrough in space-based laser power
The Japan Aerospace Exploration Agency (JAXA) and Osaka University have been working together to develop a device which converts sunlight into laser-light with four times the efficiency of previous attempts. According to a report out of Tokyo, the team is working on Space-based solar power systems which can collect sunlight in space and convert it into laser light, which is then transmitted to Earth and used for electricity... or to power a massive Death-Ray. The project works by storing sunlight-based energy in plate made from a sintered powder of metals like chromium and neodymium. When weak laser light is shined onto the plate, the stored energy is transferred to the laser where its strength is amplified by a factor of four. In one test, a 0.5-watt laser was amplified to 180-watts by the plates. Scientists have thus far been able to garner 40-percent of the solar energy produced, and they hope to have a system ready for satellite mounting by the not-too-distant year 2030. Huzzah!

It came from outer space: Live HDTV from the space station this morning
Don't forget, this is the morning of the live HDTV broadcast from the International Space Station, being shown exclusively in Japan on NHK and elsewhere on Discovery HD Theater. The Sony HD camera was donated by the Japan Aerospace Exploration Agency (JAXA), so that we can get the best look at space available without heading to the local IMAX theater. Commander Michael Lopez-Alegria and engineer Mikhail Tyurin will host the event, while third crewmember Thomas Reiter operates the camera. Hopefully this is the first of many live broadcasts, which are preferred because it saves money from transporting extra weight in the form of tapes to and from the ISS. The broadcast kicks off at 11:30 am EST and will re-air at 9 p.m. and midnight.
