Plasma thruster could propel small satellites into deep space for cheap

DNP Interplanetary CubeSat plasma thruster kickstarter project, July 4 launch

A few years from now, we might be able to send small satellites into deep space for cheap using a new propulsion system being developed by University of Michigan engineers — assuming they raise enough money via Kickstarter. Called CAT (CubeSat Ambipolar Thruster), it’s designed to propel 10 x 10 x 10 centimeter CubeSat blocks far beyond the planet’s orbit using only solar energy for fuel. Thus far, similar satellites can only orbit the Earth after going along for a ride on current rockets that are larger and more expensive. In the future, CATs could head to the asteroid belt, or even as far as Saturn and Jupiter to investigate water on their moons. The $200,000 its engineers aim to raise (in exchange for your name etched on the golden layer of a spacecraft panel) will go towards the CAT engine’s development and testing. The team could send an experimental thruster to space as soon as 2014 with help from NASA-Ames and Google, with a spacecraft launch targeted for 2015.

Planet Labs’ fleet of 28 tiny satellites will send back aerial shots for cheap

DNP Planet Labs

With the goal of capturing frequent snapshots that show the planet’s changes in real-time without breaking bank, California company Planet Labs has revealed its plan to launch 28 teensy satellites called “Doves” to space. Existing imaging satellites are extremely expensive to make and usually capture huge pictures that take days to send back. Each Dove, however, consists of relatively affordable 10-centimeter-wide Lego-like building blocks called CubeSats and will quickly beam back mid-res photos. The firm has yet to mention how many CubeSats will go into each Dove, but the two test satellites launched in April (see sample images they took at the source below) had three pieces each. If everything goes off without a hitch, the fleet could be orbiting the Earth at a low altitude as soon as December. Once operational, we can use the pictures they send to update online maps and monitor melting ice caps, deforestation, or even traffic jams.

Visualized: Cubesat micro-orbiters slip into space to flash Earth in Morse code

Visualized Japan's wee Cubesat orbiters dribble out into space

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

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.
