RE: https://mastodon.social/@sundogplanets/117043566081748429 With SpaceX's megaconstellation, we will see more satellites than stars

Prof. Sam Lawler@sundogplanets.mastodon.social.ap.brid.gy · 10h ago

And then there's SpaceX's freaking ridiculous million satellite filing. I had to reduce the frame rate for this animation because it made my computer (and me) sad. We called this the "overalls" configuration. Giant overalls, in the sky. Anytime the […] [Original post on mastodon.social]

Relatedly, Hugh Lewis just recently posted a paper showing that even by making the most conservative assumptions possible about size and orbits, and ignoring everything else that's already in orbit, all 3 of these proposed megaconstellations have so many satellites that they could cause Kessler […]

US-Indian Space Mission Maps Extreme Subsidence in Mexico City

One of the most powerful radar systems ever launched into space has mapped the ground moving beneath one of fastest subsiding capitals in the world: Mexico City. The findings show how quickly and reliably the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite can track real-time changes across Earth’s surface from orbit, unhindered by clouds or vegetation […]

Need an easy way to lookup upcoming Sentinel-2 and/or Landsat overpasses? The good news is there are for this year only three S-2 satellites in operation so more overpasses than ever. The bad news is a lot of the tools out there are outdated and will give you incorrect answers, including LLMs! […]

"The LLM era has made it very easy to make software appear, while the slower work remains: maintenance, validation, messy remote sensing details, and earning trust. Making something exist is no longer the hard part. Making something worth depending on still is." […]

In Yesterday's IO Keynote Google declared war on the remnants of the Web. While they packaged it as a lot of "AI" talk what their whole approach of decontextualizing information, of taking away links to sources and instead producing some LLM generated response means is that they want to […]
