Fly Your Own Experiment In Space

An anonymous reader writes "Want to fly your own experiment in space? dvice are reporting on a project called Ardusat — a satellite based (unsurprisingly perhaps, given the name) on Arduinos. For $500 you can upload your own code to the satellite, and run your own experiment for 1 week. Experimenters will have access to a veritable battery of 25 sensors including magnetometer, geiger counter, accelerometer, gas sensors and various others. As well as allowing for affordable space science, this sounds like it would be awesome for educational institutes."

This is A-grade linkbait, they're just spewing buzzwords and hoping certain news outlets (*cough* Hack-a-Day *cough* *cough*) will pick up on it and direct their readers to the Kickstarter page. Just looking through their writeup, it seems like they have absolutely no idea how they'll *actually process* the data; for example, they claim that they'll put a camera onboard, yet assuming that this camera uses one byte per-pixel channel and has a resolution of 160 * 180, they'll need (3 * 160 * 180)/1024KiB = 84KiB of memory to store a single frame and probably even more to process said frame. Yet the Arduino has only 1KiB of memory, and their downlink is unlikely to be able to transfer a whole frame in a reasonable amount of time (so no live video). That's only one of the big holes in their plan, here are some of the others:

• They plan to put a GPS onboard, but commercial GPS receivers shut off when they reach 60, 000ft and 999kt. The satellite will exceed both of these limits mere seconds after it leaves the launchpad
• They haven't explained *how* they plan to launch the satellite into space, or why it's costing them a mere $35, 000
• As pointed out above, it's unknown what advantage there is to running code *onboard* the craft when you could simply analyse the data on the ground
• None of their sensors are designed to operate in space. How will their pressure sensor work in a vacuum? Is their temperature sensor rated to work at extreme temperatures? It doesn't sound like it.

tl;dr parent is right and this is a giant load of bullshit.
