When sending satellites into space, the idea is to place them into as stable an orbit as possible in order to maximize both the time the satellite is useful and the economics of sending it there in the first place. This tends to become rather untenable as the amount of space junk continues to pile up for all but the lowest of orbits, but a team at Brown University recently tested a satellite that might help solve this problem, at least for future satellite deployments.

The main test of this satellite was its drag sail, which increases its atmospheric drag significantly and reduces its spaceflight time to around five years. This might make it seem like a problem from an economics standpoint, as it’s quite expensive to build satellites and launch them into space, but this satellite solves these problems by being both extremely small to minimize launch costs, and also by being built out of off-the-shelf components not typically rated for spaceflight. For example, it gets its power solely from AA batteries and uses an Arduino for its operation and other research.

The satellite is currently in orbit, and has already descended from an altitude of 520 km to 470 km. While it won’t help reduce the existing amount of debris in orbit, the research team hopes to demonstrate that small satellites can be affordable and economically feasible without further contributing to the growing problem of space junk. If you’re looking to launch your own CubeSat one day, take a look at this primer which goes over most of the basics.

Short of scoring a spot on the ISS experiment docket, putting your scientific aspirations into orbit can be a bit tricky. Why not try crowdsourcing your way into space? ArduSat's barking up that very tree, asking Kickstarter contributors to help them get a Arduino CubeSat off the ground. Headed by NanoSatisfi, a tech startup operating out of NASA's Ames Research Center, the project hopes to raise enough funds to launch an Arduino bank and a bevy of open-source sensors into orbit. The payoff for backers? Access. Varying levels of contribution are rewarded with personalized space broadcasts, remote access to the space hardware's onboard cameras and even use of the machine's sensors to run experiments of the backer's own design. If all goes well, the team hopes to launch more satellites for the everyman, including a unit dedicated to letting would-be stellar photographers take celestial snapshots. Sure, it's far cry from actually launching yourself into the stars, but would you rather be a tourist, or a scientist? Check out project at the source link below, and mull over that for awhile.

ArduSat wants to put Arduino satellite, your experiments into orbit originally appeared on Engadget on Mon, 18 Jun 2012 04:02:00 EST. Please see our terms for use of feeds.

CubeSats are nothing new – hundreds have been launched into Earth orbit by schools and universities over the past decade. Like anything cool, an Arduino eventually gets thrown into the mix. That’s what the folks behind ArduSat are doing: they’re launching an Arduino-laden satellite into orbit with a bunch of sensors to enable anyone to become a citizen space scientist.

On board the ArduSat is a suite of sensors including a spectrometer, Geiger counter, IR light sensor, electromagnetic wave sensor, a temperature sensor, gyroscope, accelerometer, magnetometer, GPS unit, CO2 sensor, and of course a few cameras. The rewards for this Kickstarter are fairly interesting: backers who pledge $500 are able to buy a week’s worth of time using the ArduSat sensors for your own personal experiment.

As for how this Arduino-powered satellite is getting a ride up to Low Earth Orbit, the team plans to send an application into NASA for the CubeSat Launch Initiative ride-along program. If NASA selects the ArduSat, it’ll get a ride into space along with other CubeSats on a larger commercial launch. If the ArduSat isn’t selected by NASA, the team behind this satellite has secured funding to piggyback on a commercial launch.

Tip ‘o the hat to [HackTheGibson] for sending this in.
