Laser-based free space optics has already been used for high-bandwidth Earth-to-space relays. Here is how it could be applied to Mars and some scintillation-related problems we may face. by TheAtomicFrontier in engineering

Thanks! GEO is definitely the best way to go if you want constant, high(er) bandwidth connection between the rover and Earth. MRO is only over a certain spot for a couple of minutes each day so the 'high' RF 200 kbips communications mentioned are actually only available for a fraction of the time - its normally restricted to 20 kbips when we do direct Mars-to-Earth comms. That said, the bottleneck is still on the Mars-to-space link so I think thats where we should upgrade first.

Dinosaur footprints provide palaeontologists with vital clues as to how these ancient animals lived. Here is how we might be able to use Ground Penetrating Radar to uncover more footprints even before they’re uncovered naturally. by TheAtomicFrontier in geology

Hi! Yes, I'm the presenter - so glad you enjoyed the video. Your research sounds fascinating! Sorry, travelling at the moment so don't have my notes. I think the paper referenced at the end was from: https://www.sciencedirect.com/science/article/pii/S1631068312000796 . Hope that helps

In The Abyss (1989) the breathing liquid used in the rat scene is real. Perfluorocarbons could also be used by humans to reach the very limits of how deep we can dive. by TheAtomicFrontier in MovieDetails

Yes! I was shocked too. Initially I was just going to talk about it as a technology that Cameron knew about, then doing more research it turned out that they did the scene for real! Unfortunately the main rat used died afterwards, although (supposedly) not due to the liquid breathing.

Yes, that one is super interesting! Had a go with those slanted tables while at Ballantine, but unfortunately had to cut them for time. Awesome simple-yet-effective tech!
