If you live in the Eastern portion of the United States and the skies are clear you can see a student built satellite flashing LEDs in Morse Code today. But don’t worry. If you it’s cloudy or if you live elsewhere there are several other opportunities to see it in the coming days.
This is the Niwaka Fitsat-1. It was developed by students at the [Fukuoka Institute of Technology] and deployed from the International Space Station on October 4th. Included in the payload is an array of LEDs seen in the image above. On a set schedule these are used to flash a Morse Code message for two minutes at a time. That is what’s shown in the image on the upper right.
You can look up information on seeing Fitsat-1 in your own area using this webpage. All of the observation windows in our area require a pair of binoculars or better. We’re not sure if there is any case in which this can be seen by the naked eye.

We absolutely love these stories of hacker ingenuity saving peoples lives. In this case, it was aboard the ISS, and the item being hacked was a toothbrush.
The story is as follows. Some equipment failed, as space junk tends to do, and the astronauts found themselves needing to do some repairs. Upon inspection, they couldn’t remove some modules due to an accumulation of “space dust” around some bolts. This was especially troubling as the unit in question was something that was supposed to route power from some of the solar arrays to the ISS. Even more troubling is that another unit failed while they were assessing the situation.
Realizing they had to act fast so as not to lose too much power to function, they cobbled together some tools to allow them to clean out the access ports and remove the units for repair. A task that sounds like an easy solution here on earth proved to be life threatening in space. Eventually though, their makeshift tools came to the rescue and they were able to repair and restore power.
We had a lot of fun with that title. Of course when you’re talking about launching a thousand ping pong balls into space there’s no end to the puns which can be made. But this is actually a fantastic initiative to get people of all ages excited about science and near-space experiments. [John Powell] offers school children the opportunity to send an experiment into space. He’s Kickstarting the next launch, which is scheduled to take place in September. This way each entrant can fly their project for free, then get the results and a certificate back once the weather-balloon-based hardware is recovered.
There is one size restriction for the program. Each experiment must fit inside of a ping pong ball. But you’ll be surprised what can be accomplished. [John] reports that the most simple, yet interesting project is to place a small marshmallow inside the ball. As it rises through the atmosphere it will grow to fill the entire ball, then be freeze-dried by the the extreme temperatures. Some are not so low-tech. There’s an image of a tiny PCB holding a DS1337 and some sensors. It’s an atmospheric data logger that will provide plenty of information to analyze upon its return.

Earlier today we posted a link to a tournament NASA is holding. NASA is trying to crowdsource the organization of terabytes of data collected from missions all over the solar system. A few Hackaday readers wrote in (thanks [grbgout] and all the others) to tell us there is an International Space Apps Challenge going on this weekend to crowdsourse solutions to the problems of space flight.
The challenge is the product of a partnership between NASA, the National Science Foundation, the UK and Japanese Space Agencies and a host of other organizations like GitHub, Yahoo Developer Network, and even a few hackerspaces. The idea behind the challenge is simple: spend a weekend solving software, hardware, and science challenges to improve the state of space sciences.
There are a lot of interesting projects like programming an interface to a NASA mission simulator, figure out how to print 3D objects in space, and even develop the hardware and software for an underwater ROV.
Aside from the fancy software and hardware challenges, there are also some very interesting data visualization problems, like clearly explaining the fact that space is mostly empty. If you can figure out how to tell people they aren’t the center of the Universe, take a shot at it – there’s probably a Nobel in Literature in it for you.
Right now there are dozens of locations on all seven continents and in Low Earth Orbit (McMurdo Station in Antartica and the ISS) that will have people contributing to these projects. Of course you’re free to work out of the home and help scientists, engineers, and researchers reach to the stars.
The Swiss plan to clean up the near-space environment. They just announced a debris removal device which they plan to launch in three to five years. The first goal of the program is to scoop up two satellites. Both of them are Swiss owned, but there’s something very James Bond like that pops into our heads when we hear that.
We’re sure you already know there’s a space junk issue in orbit. But did you know that NASA tracks a half-million pieces of orbital debris? Cleaning that up does sound like a good thing. The plan is to detect the offending item, match its trajectory, grab it somehow (which includes halting any spinning that it’s doing), then encapsulating everything for an eventual re-entry. Looks like they plan on the whole robot burning up along with the junk during that final stage.
We keep hearing about ways robots will clean up the messes we make. Hopefully we’ll see these in action at some point.
Take the risk of not recovering your hardware out of a near-space camera launch by streaming the data during flight. [Tim Zaman] is part of a team that developed the rig seen above. It sent 119 image back during the recent balloon launch. This included transmissions from as high as 36 kilometers.
The main hardware included a BeagleBoard with connected Webcam housed in a Styrofoam cooler for thermal protection. Pair that with a GPS module for location tracking, and a GPRS module for data transmission and you’re in business.
But that’s not all that went up. The team built a backup hardware module in case the primary failed. This one also had a GPS and GPRS radio, but was driven by an Arduino.
The radio connection made it easy to recover the hardware. GPS data led the team directly to the landing site. The package came to rest on the roof of a building, but we guess that’s more convenient than getting snagged at the top of a huge tree.
Don’t miss the hardware detail video that we’ve embedded after the break.

[Thierry Legault] doesn’t just look up at the stars, the uses a motorized telescope base of his own making to track and photograph secret objects orbiting the earth. What do we mean by ‘secret objects’? Spy stuff, of course.
Last month he captured some video of the X-37B, an unmanned and secretive reusable spacecraft (read: spy shuttle) which is operated by the United States Air Force. That was back on the 21st of May but a few nights later he also saw the USA-186, an optical reconnaissance (Keyhole) satellite.
After trying to cope with manual tracking using the RC control seen above [Thierry] set out to upgrade his equipment. He ended up designing his own software package (and then released it as freeware) to automatically track the trajectory of orbiting objects. He uses a second telescope to locate the object, then dials it in with the bigger telescope. Once in frame, the software takes over.
