It doesn't appear to include any objects in the GEO belt (which space-track does), so I'd guess it's just objects from LEOlabs's own sensors.

LEOlabs operates its own radar systems that point upwards-ish. The "beams" you see are the fields of view of their radars. When an object crosses that field of view going at orbital speeds, LEOlabs tracks it and uses the partial

Some examples exist for directly converting alpha, beta, and gamma particles into electricity, but I didn't find anything for neutrons in my brief search. https://en.wikipedia.org/wiki/Atomic_battery#Radiovoltaic_c

Most SpaceX hardware works this way: off-the-shelf processor, triply redundant, using voting to figure out if one is wrong.

Is the "Merges" section true? In factorio, since belts have two lanes, a T-intersection merge like the one pictured doesn't zipper; instead, the left belt feeds onto the left lane of the central belt and the right belt feeds

Public safety is mostly funded at local and state levels. Public school is half funded by local government and half funded by the state. TFA is about federal taxes.

I've heard OneWeb's constellation ops team (the engineers in charge of coordinating maneuvers with other spacecraft for collision avoidance) threatened to walk out over the crazy press tirade. The craziness was from someone at th

Yep! Looks like the authors of the first paper I read on it (glass microspheres in silver-backed clear plastic film) are finally starting to commercialize it too... http://radi-cool.com/technologies/

I'd bet that data is from sensors with low heat dissipation. Unfortuantely, humans produce ~100W of heat each. If you're using a small underground basement as a place to escape lethal heat aboveground, or even a large undergroun

Electromigration can happen because of constant high temperatures as well!

I'm a spacecraft thermal engineer (not in remote sensing), and this sentence leapt out at me. Do you have any example papers on microbolometer advances you could share? > We’ll also be taking advantage of advances in microbolometer

Etymonline disagrees; -plane here is from French planer "to soar," ultimately from Latin planus, "flat." http://www.etymonline.com/index.php?term=aeroplane

Yeah, this sounds prone to malicious abuse, mostly because of the subject matter. I've heard of occasional malicious use of Youtube copyright claims, but in the case of fake news on Facebook, the same system seems like it would devolv

I'll repost the comment I made over there: Have you guys heard about the entire field of study that is aerospace medicine? I’m taking a course on it this semester (I’m a masters student in aerospace engineering)–let me summarize some o
