The leadership of the American Astronomical Society explains why "move all the telescopes to space" is neither possible nor desirable: spacenews.com/the-future-o...
I would only add that there are individual telescopes that mass more than everything ever launched into space put together.
Right OK so what can you do? Great news, especially if you're in the US (insert feelings here), both @darkskyintl.bsky.social and @aas.org 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.
I know! It seemed like The. Most. Obvious. HST proposal when I noticed it myself! Glad we were able to get the observations in before HST transitioned to one-gyro mode

The distance to NGC 4303 is similar to previous estimates, but the distance to NGC 1068 is quite different than usually assumed. That's important for lots of studies!

New paper day! In an effort led by PhD student Madison Markham, we determined the first accurate and precise distances to two famous AGN host galaxies: NGC 1068 and NGC 4303. Using the Hubble Space Telescope, we identified Cepheid pulsating stars and measured their pulsation periods and mags ππ§ͺ(1/2)

Supernova 1987A is located in the centre of the image amidst a backdrop of red, blue, and orange stars. A bright pink and red ring around the central region of the exploded star is composed of material ejected by the star about 20 000 years before the actual explosion took place. The supernova is surrounded by red and orange gaseous clouds. The color of these clouds represents the glow of hydrogen gas.
Light from supernova 1987A reached Earth #OTD in 1987.
The Hubble space telescope captured this spectacular image for the 30 year anniversary in 2017. π§ͺ π βοΈ
