From the website:
“The Lazuli Space Observatory is a 3-meter–class space-based astronomical facility designed for rapid-response observations and precision astrophysics across optical and near-infrared wavelengths.”
And we wall should be happy he doesn’t want to put a swarm of micro telescopes into the sky to mimic his approach for the ground based telescopes.
The last thing astronomy needs is even more satellite constellations polluting the night sky.
- BurningFrog 10mo agoSatellites are only visible when it's dark on the ground but sunlight at their orbit. Which is for a short time around sunset and sunrise. During the actual night sky, you don't see satellites. As civilization moves into space, it will have to be visible! Imagine if cities were only allowed it they were invisible. Let's not be this stupid! That said, I'm sure a lot can be done to minimize reflections using paint and materials.
- defrost 10mo ago> During the actual night sky, you don't see satellites. Cool. So what's the beef radio astronomers, the SKA people et al, have with SpaceX all about then? Any chance you haven't thought this through at all?
- BurningFrog 10mo agoCome on, at least find out what the "beef" you support is about!
- defrost 10mo agoNot the visible spectrum, that's for sure.
- BurningFrog 10mo agoOh, that's an interesting angle. Satellites emitting radiation would really be a 24/7 problem. Ultimately, astronomical observatories should be in space anyway.
- defrost 10mo ago+1 for working out the issue on your own. As commentary: > at least find out what the "beef" you support is about! It's a problem many wish to see resolved, it's not a fight I "support" like a punter at a boxing match. I guess if I wanted to find out more about this "beef" I might read a paper, talk to a person, or go to a conference. * Bright unintended electromagnetic radiation from second-generation Starlink satellites - https://www.aanda.org/articles/aa/full_html/2024/09/aa51856-24/aa51856-24.html https://www.aanda.org/articles/aa/full_html/2024/09/aa51856-... * Federico Di Vruno https://orcid.org/0000-0001-7454-7883 https://orcid.org/0000-0001-7454-7883 * Centre for the Protection of the Dark and Quiet Sky - https://cps.iau.org/ https://cps.iau.org/ Thank you for that suggestion. > Ultimately, astronomical observatories should be in space anyway. Well, that's certainly an opinion. There's a wide range of survey programs and in terms of bang for buck it makes sense for some to be in space, others not so much. Ultimately there should be somewhat less space junk in LEO's but sadly that's a problen that is only going to get worse now multiple parties want oversized SpaceTwitter type constellations.
