Hubble turned 30 yesterday and I actually stopped what I was doing to mark it, which is more than I can say for most anniversaries of anything. April 24, 1990 — that's when it went up on the Space Shuttle Discovery, STS-31, if you care about mission numbers (I do, a little, in the way you care about trivia you'll never need). Thirty years of one telescope is a genuinely wild stretch of time when you think about how much of the tech we use now didn't exist ten years ago, let alone thirty.
NASA marked the day by releasing a new image, the "Cosmic Reef" one — two nebulae sitting next to each other in the Large Magellanic Cloud, all pink and blue and looking like something out of a screensaver except its real, or at least real in the sense that colorized deep-space photography is real (that's its own rabbit hole and I'm not going down it tonight). I pulled it up on my monitor and just sat there for a minute. Havent done that with a piece of tech news in a while.
What I actually want to talk about is the part of the Hubble story that never gets enough airtime, which is that the thing launched broken. Spherical aberration in the primary mirror, off by a fraction most people would call negligible, and it was enough to make the first images embarrassingly blurry. This was a multi-billion dollar telescope sending back pictures worse than what a decent backyard scope could manage, and NASA had to eat that publicly for three years until a 1993 servicing mission went up and basically fitted it with glasses (the COSTAR corrective optics package, for anyone who wants the actual term). I think about this a lot when people act like a shipped product has to be perfect on day one or its a failure. Hubble is one of the most important scientific instruments humans have ever built and it spent its first three years as a punchline.
Anyway. I dragged my telescope out to the back deck last night, which is not a Hubble-grade instrument by any stretch. It's a cheap Newtonian reflector I bought used maybe eight years ago and never really learned to use properly. Point of pride, though: I did manage to find Venus without much fuss, which is not hard right now since its stupidly bright in the western sky after sunset, but it still felt like an accomplishment given the last time I tried this I couldn't even get the finder scope aligned. Small wins. The neighbor two doors down has a motion-sensor floodlight that keeps tripping every time a cat walks by, and it wrecked my night vision twice, which is exactly the kind of thing that ruins backyard astronomy and nobody warns you about before you get into it.
Its a strange time to be looking up, honestly. Everyone's stuck at home right now with the stay-at-home order still going, and there's been this whole secondary trend of people rediscovering stuff like stargazing and sourdough and jigsaw puzzles because there's nowhere to go and nothing else to do after 8pm. I dont think its a coincidence that a lot of us are suddenly paying attention to something that's been sitting up there this whole time, quietly working, while everything down here has felt like its on fire for a month straight. NASA's anniversary livestream had some audio sync issues when I watched it, which, fine, everyone's home internet is getting hammered right now and I'm not going to pretend my own video calls have been flawless lately either.
I keep seeing people frame the last few weeks as this huge moment for video calling apps, everyone racing to add more features and bigger meeting rooms, and sure, thats a story, but it's not the one that stuck with me this week. Hubble did its actual job for three decades with basically no fanfare in between the big headline moments, and it took getting fixed once to become one of the most reliable pieces of technology anyone's ever pointed at the sky. There's something about that pace, that patience, that feels like the opposite of everything going on right now, and I mean that as a compliment.
Going to try for Jupiter and Saturn one of these nights before it gets too late in the season. Need a better finder scope first. That's next weekend's project, assuming the hardware store down the street is even still doing curbside for that kind of thing.
