Short Video Recaps A Long Tradition Of Space Hacks

Human spaceflight has always been, and still remains, a risky endeavor. We mitigate risk by being as prepared as we can. Every activity is planned, reviewed, and practiced long before any rocket engines are ignited. But space has a history of not cooperating with plans, and thus there is a corresponding history of hacks to get missions back on track. YouTube space fan [Scott Manley] recaps some of his favorites in How a $2 Toothbrush Saved the ISS and Other Unbelievable Space Hacks.

The introduction explained this compilation was motivated by the latest International Space Station drama, where an elusive air leak has finally been tracked down. Air leaks are obviously much more worrying in a space station than in, say, a bicycle tire. Thus there exists a wide array of tools to track down leaks but they couldn’t find this one. Reportedly the breakthrough came from an improvised airflow visualization tool: leaves from a cut-open tea bag. Normally small floating particles are forbidden in space because they might end up in troublesome places. (Eyes, noses, onboard equipment…) Apparently the necessity of the hack outweighed the rules here.

Tea leaves are but the latest in a long line of hacks devised in the course of space missions, because things don’t always go according to the original plan. Or even any of the large volume of contingency plans. Solutions have to be cobbled together from resources on hand, because when we’re in space, what we brought is all we have. From directly editing production code during Apollo 14, to a field-built replacement fender for the Apollo 17 Lunar Rover Vehicle (top picture), to the $2 toothbrush pressed into service as metal debris cleaner. The mission must go on!

Don Eyles Walks Us Through The Lunar Module Source Code

A couple weeks ago I was at a party where out of the corner of my eye I noticed what looked like a giant phone book sitting open on a table. It was printed with perforated green and white paper bound in a binder who’s cover looked a little worse for the wear. I had closer look with my friend James Kinsey. What we read was astonishing; Program 63, 64, 65, lunar descent and landing. Error codes 1201, 1202. Comments printed in the code, code segments hastily circled with pen. Was this what we thought we were looking at? And who brings this to a party?

A Replica DJ Controller To Rule Them All

So like many followers of Hackaday, maybe you’re into electronic music. We’d dare to say though that few of you have the dedication of [adamdzak] as he decided to replicate [Sasha]‘s custom controller for the [Abelton Live] software package. Apparently it’s more difficult than taking apart your DJ Hero controller and hacking it to interface songs on your computer.

The “new” controller is named Apollo, and is meant to be a replica of Sasha’s Maven controller. The build process is well laid out in his post, and the results so far look quite incredible. What’s particularly interesting is the effort taken to reverse engineer this device without ever having been able to use it. Both from a mechanical standpoint and trying to figure out how the buttons are used to control the software must have been quite a challenge. Check out the video after the break to see this new controller in action. Continue reading “A Replica DJ Controller To Rule Them All”
