This week has been a long year First, ICYMI, @[email protected] hit a HUGE milestone with our live alert stream going public. I've worked on various aspects of this since joining UW and @[email protected] in late 2016. Learn more about how this works, including how to access the data:

Alert Stream | Rubin Observatory

Explore how Rubin Observatory will identify changes in the night sky—and let the world know about them within minutes.

Meanwhile, since January, some 1.6 million satellites have been proposed. This is bonkers, and it's getting mainstream media attention thanks to the hard work of many wonderful colleagues @[email protected] coauthored a pair of articles theconversation.com/too-many-sat...

Too many satellites? Earth’s orbit is on track for a catastrophe – but we can stop it

Cultural, spiritual, and most environmental impacts aren’t taken into account when launching thousands of satellites.

A new space race could turn our atmosphere into a ‘crematorium for satellites’

Planned ‘megaconstellations’ of satellites could cause unforeseen harm to the ozone layer and climate systems. Global regulation is needed before it’s too late.

The Conversation
If that has you down, well, welcome to the resistance or something, read this one next. It's a response to an impressively incorrect piece titled "It is time to take astronomy off Earth" and it's by a whole host of @[email protected] past presidents and it is perfect spacenews.com/the-future-o...

Meanwhile, the mainstream news media is actually paying attention, because the FCC comment deadlines for both 1 million AI orbital data center satellites (yes, you read that right) and a demonstration space mirror reflector (also sadly correct) is March 6 and 9, respectively

We’re about to turn night into day. Is that a good idea?

Proposals before the FCC involve mirrors that could bathe entire cities in sunlight and, from SpaceX, a million satellites to serve as data centers.

The Washington Post
What's that? You don't have enough tabs open to learn about how billionaires want to permently alter Earth's orbital space environment? OK then

SpaceX's Ambitious Plan for 1 Million Satellites Faces Growing Environmental Criticism

SpaceX's proposal to launch one million satellites into orbit has ignited a fierce debate between technological innovation and environmental preservation

Space X Wants to Launch 1 Million Satellites, but Is There Room?

Elon Musk wants to launch a million satellites, but researchers say global warming is changing the upper atmosphere in ways that makes space junk linger.

The New York Times
Satellite data centers might help Earth. But what about space?

As tech companies and governments fill the night sky with satellites, some astronomers are urging caution about creating a “dumping ground’’ in orbit.

The Christian Science Monitor
Right OK so what can you do? Great news, especially if you're in the US (insert feelings here), both @[email protected] and @[email protected] have handy guides for how to write an FCC comment. This is sort of astronomers' equivalent of "call your elected officials" kind of call to action, for context.

You don't have to be a professional astronomer to do this, and you don't have to have your talking points perfectly sorted out. You can just write a short letter telling the FCC why you think granting a licence to operate the proposed satellites is a bad idea. Another how-to: aas.org/posts/advoca...

To come full circle, you may logically be wondering, well wait, if Rubin Observatory is turning on, and the sky is filling with satellites, isn't that a problem? SURE COULD BE And addressing that is literally what my job is, right now, most of the time. Back to it. 🔭
@merrdiff.bsky.social @sundogplanets If we end up with our planet enshrouded with a veil of satellite debris, we will,at least be shielded from any future communications from aliens! So we can save on all that!
