Crowd sourcing your telemetry collects is cool but something feels Fucky to me about saving money on a ground station by exploiting hobbyists If HAMs are your collectors, you better be paying them

"we had an electrical fire during integration" I've honestly been sleeping through this very undergrad presentation but that sentence snapped my head up like a mousetrap

Next up is passive thermal control for small spacecraft, by University of Manitoba Thermal contol is important because vacuum is an insulator, and components need temperatures cooler than insolation (sun exposure) or hotter than eclipse (in Earth's shadow)

She is presenting a smart radiator, which combines the radiator's simplicity and the louver's controlled heat emission A Vanadium Dioxide film doped with Tungsten can, apparently, scale its heat emission flux with temperature

TVAC testing shows promising results of emissivity proportional to temperature. I would have naïvely expected that all materials do this? Maybe the effect is significantly greater for these materials, or my assumptions are incorrect. Anyway, passive scaling is cool.

University of New South Wales presents on-orbit calibration of a magnetometer using stochastic gradient descent This is largely a statistics presentation, with few quotable bits. It's very interesting, just hard to tweet.

I dislike that it's pitched as "machine learning recalibrates sensors" but wcyd

No offense to component manufacturers but I'm gonna skip posting about the reaction wheels talk
