Comment Re:Pump and dump is a crime (Score 1) 160

I'd bet the worker-bee employees at gamestop are pretty concerned right now too. Not the teenagers at the stores as much as the people in their 30s and 40s that work for the company sales, marketing, IT, accounting etc that have mortgages to pay and kids to feed.

How are the worker-bee employees affected by gyrations in the stock?

Comment Outgassing (Score 1) 165

On the face of it, it seems outgassing (release of gas within a material) would be a horrendous problem.
With metal it's a significant issue for many spacecraft where volatile material within the metal is released in space,
but can then condense on cold parts of the satellite. That can be particularly bad if it's condensing on your detector which is
cooled for e.g. IR detection.
With all the organic material of various types inside wood, it would seem that it would become far far worse.

Comment Re:US infrastructure crumbling. (Score 5, Informative) 58

Except it isn't "US infrastructure". It is owned by The Ana G. Méndez University National Science Foundation of the University of Central Florida, not the U.S. government.

You seem to have got three institutions munged together here.
UCF and Universidad Ana G. Méndez operate the Arecibo observatory under an agreement with the NSF.
Arecibo is an NSF facility, and so very much part of the US.

Comment Re:Still insufficient data (Score 4, Informative) 106

I've not been able to get well researched answers to some simple questions [...]I haven't even seen anyone make a serious effort in answering these questions. Without quantifiable data how am I supposed to know if I should care, how am I supposed to know if this is a significant issue?

The National Science Foundation and the American Astronomical Society hosted a workshop on the effects of satellite constellations on astronomy in July and the presentations are available here:
https://aas.org/satellite-cons...

This workshop gathered together astronomers, satellite operators, dark-sky advocates, policy-makers, and other stakeholders and interested parties to discuss, understand, and quantify the impacts of large satellite constellations on astronomy and the human experience of the night sky. The goal was to work collectively towards effective solutions to mitigate those impacts and to publish them in a report which will be widely distributed.

Comment Re:Is it really a big problem? (Score 5, Informative) 110

I'm a professional astronomer.

When I work with multiple images it's because I use the individual images to derive light curves. I certainly don't want to lose my timing information by combining them all together. I rarely come across instances in the literature (i.e. ApJ, A&A, MNRAS etc.) where people are co-adding many images of the same field (certainly not "thousands").
