Japan's Venus probe is about to take another shot
Japan tried and failed to get its Akatsuki ("Dawn") probe into Venus' orbit back in 2010, and the spacecraft has been stuck orbiting the Sun ever since. However, the team is about to get another chance at completing its intended mission. Controllers plan to fire the ship's engines on December 7th at 9AM Japan time (December 6th 7PM ET), hopefully giving it just enough of a push to (eventually) get it circling around Venus. They'll know whether or not the burn worked properly within a few hours, but it'll take a few days before they know if they're in orbit.Update: The attempt is happening in just a few minutes, for live updates you can watch a stream of the data and control center, or follow Emily Lakdwalla on Twitter.
Visualized: Cubesat micro-orbiters slip into space to flash Earth in Morse code
Japan's four-inch FITSAT-1 orbiters were released from Japan's Kibo laboratory on the ISS last week to (literally) start their world tour, and astronauts aboard the station captured the wee satellites being dwarfed by giant solar arrays and our own blue rock on their way to orbit. Soon they'll be writing "Hi this is Niwaka Japan" in Morse code using intense flashes of LED light, first to Japan and then across the globe, starting next month. To catch them floating away from the International Space Station's cozy confines, hit the source.
Japan's LED-stacked cubesat will burn Morse code into the heavens
If you thought cloud writing was cool, then how about a message from space burnt into the night sky? A group of unassuming cubesats recently left the comfort of the ISS and joined Earth's orbit -- among them was FITSAT-1 (aka Niwaka), a four-inch-cubed Japanese satellite covered in high-powered LEDs. Its mission is to broadcast the message "Hi this is Niwaka Japan" in Morse code, using bursts of intense light to draw dots and dashes across the heavens. FITSAT-1 was originally planned to appear only over Japan, but a flurry of interest means it'll be touring the globe, starting next month. It'll also find time for its studies, beaming VGA images snapped with an onboard camera back to Earth, to test a high-speed data transmitter. While its creator, Professor Takushi Tanaka, has said the Morse broadcast has "no practical aim," we think it would make a good emergency beacon for natural disasters (or, more worryingly, alien invasions). FITSAT-1 will try and fulfill all requests for appearances, but it can't control the weather, so you'd better hope for a clear night if it visits your part of the world. If you're as excited as we are to see it in action, bookmark the source links below, which should be updated with its orbit schedule in the near future. And, even if you don't speak Japanese, the video after the break will give you an idea of what to expect.
Japan sends Kounotori 2 spacecraft on suicide mission to study re-entry process
An unmanned cargo ship built by the Japan Aerospace Exploration Agency (JAXA) is set to go up in flames tomorrow in the name of interplanetary research. Along with a load of space station junk, the Kounotori 2 spacecraft is packing something akin to a black box, also known as a Re-entry Breakup Recorder (REBR), that will collect and transmit data about the ship's final moments. The space station's crew will activate the REBR before Kounotori 2 begins its final assignment. As soon as it starts showing signs of re-entry, the sensor will begin to collect data including temperature, acceleration, and rotation rate, and will then break away from the craft for a final free fall to Earth, at which point the REBR will dump its findings. Scientist hope the device will help answer questions about exactly what happens when things fall apart during re-entry. If all goes according to plan, the REBR will plunk down in the ocean sometime later, but its host will never be seen again... farewell, Kounotori 2.
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.
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.
