These low orbits aren't stable though, I think they only have a lifetime of 10-20 years before their lateral velocity decays and they de-orbit on their own, it's not like will just be stuck up there.
- skrause 9y agoNo, with orbit altitudes of 1,110km to 1,325km we're talking about many hundreds of years: https://www.nasa.gov/news/debris_faq.html https://www.nasa.gov/news/debris_faq.html - "Debris left in orbits below 370 miles (600 km) normally fall back to Earth within several years. At altitudes of 500 miles (800 km), the time for orbital decay is often measured in decades. Above 620 miles (1,000 km), orbital debris normally will continue circling Earth for a century or more. "
- Neeek 9y agoAh, I was under the impression that to achieve 25ms latency you would need something very low but it seems to be almost anywhere in LEO would give you close to those speeds. I was thinking of older speculative articles where HN discussions seemed to think they would only be 300-500 kilometers up, this article states otherwise.
