I love the phrasing in “… is now operating with all four active instruments collecting science.”

Reminds me of strategy games where feeding enough “science units” into opaque “research labs” unlocks branches of the technology tree.

[+] throwawaylinux|4 years ago|reply
They're collecting observational data, not science. I wouldn't normally be bitter about it, but the Trust The Science™ religion already has a terrible struggle with the basics so we shouldn't make it any harder for them.

My back yard rain gauge is not sciencing either.

Hah! You make it sound like they said "You must construct additional pylons," or something. :)

What's the proper unit of measurement to quantify how much "science" they've collected, anyway? Bits?

But research labs would consume raw materials like wood, metal, Vespene gas, etc., and produce science units that could then be spent to climb the tech tree, no?

It also makes me think of Portal: "And the science gets done, and we built a neat gu--er, telescope..."

Or Scully babbling on about "the science", referring to some MacGuffin or other during the later seasons of the X-Files.

Amazon just had an outage on their computers localized to a 3 mile region in Virginia and they still haven't fixed it.

NASA had an outage 350 miles above the surface of the Earth and managed to fix it.

There's a difference in software reliability priorities and operations here.

The purpose of NASA is not only to explore but inspire. In light of that, I'd be fully supportive of using a Starship launch to bring Hubble home.
[+] wolverine876|4 years ago|reply
Hubble has been accomplished completely without SpaceX, as is James Webb and almost all other amazing advances in space. What do you think about the organizations and people that actually accomplished these things?
[+] _moof|4 years ago|reply
I'm not sure I understand what you're getting at.
[+] mjevans|4 years ago|reply
If Hubble were brought back, where would it go?

I assume anything remotely still classified would be ripped out, so probably only the big (outer) shell would end up in a museum, maybe some of the outdated computer boards.

It's still inspiring, but would it be more fair to go to Florida? Texas? Some state where it was built (if it weren't those)? The Smithsonian?

To service and relaunch for the next 50 years?
[+] ianvorbach|4 years ago|reply
That's a fun idea! I don't see how you would execute that unfortunately though. Hubble wasn't meant to be re-mounted after deployment. Starship wouldn't be able to just gobble Hubble up and have it rattle around in its fairing during re-entry
[+] make3|4 years ago|reply
As far as I understand it, that sounds super useless though.

Maybe we should inspire people by doing useful science instead.

[+] skurtcastle|4 years ago|reply
That's awesome to hear.

I'm excited for Dec 22nd when the James Webb launches. Crossing fingers big time.

[+] xattt|4 years ago|reply
I’m looking forward for some of the photo series NASA probably has planned, like a simultaneous observation of the same object with Hubble and Webb.
[+] bryanlarsen|4 years ago|reply
30 days off terror for it to transit and unfold. Scary times!
[+] echelon|4 years ago|reply
The vibration incident was solved?

This launch is going to be so scary as it represents the scientific promise and investments of a generation.

One of NASA's biggest mistakes wrt the demise of the STS/Shuttle program was not leaving some way lined up to service Hubble in orbit. The current crop of launch vehicles isn't suited to this task, despite us being ten years out from STS-135.

It's proven itself an absolutely invaluable tool for research, but I think the even more impressive mission Hubble has shown itself as irreplaceable for is stimulating the public's mind for science and exploration. There's nothing like seeing photos of the universe in visual-light spectrum and thinking, "what if we went there?"

JWST is amazing and I'm so glad it's finally launching but for that second use case, it trails Hubble.

I wouldn't lay the blame on NASA. Congress ultimately decides what NASA does and does not do.

Constellation was the system that was supposed to succeed the Shuttle. It had one successful first-stage launch in October 2009. In 2010, Constellation was cancelled by Congress (at the behest of then-president Obama). In its stead, Congress essentially designed a new rocket called the Space Launch System, and tasked NASA with building it. Constellation's crewed capsule, Orion, survived as the SLS's crewed capsule. Unfortunately, the SLS is now 5 years overdue for its first launch. (It currently seems reasonably likely to launch for the first time in 2022.)

The Orion capsule could conceivably service Hubble [1], especially after lots of launches and general experience with the vehicle. If Constellation had not been cancelled, or if Congress had tasked NASA with a less-ambitious rocket to build, (or if the contractors that NASA was obliged to use to build the SLS had been able to keep to the original schedule,) we might have had a spacecraft to service Hubble right now.

I think JWST will be an amazing replacement as most space photos are doctored with visible light "interpretations" of other wavelengths already and nobody seems to notice/care as they have their minds blown. The process almost even adds to the beauty of them.
[+] duxup|4 years ago|reply
I thought the experience they had servicing Hubble actually meant that they generally didn’t want to have satellites that they would have to service due to costs involved.

Maybe with the new options it becomes cheaper/ more viable.

[+] nradov|4 years ago|reply
How was that a mistake? What was the alternative?

For the near term it's always going to be cheaper to launch replacement satellites instead of servicing broken ones in orbit.

Having worked at Lockheed on the engineering side of Hubble for four summers as an intern during undergrad, the idea of the telescope reaching its end of life makes me deeply sad.
[+] keyle|4 years ago|reply
That warms my heart somehow, but I thought I had read that that was it for Hubble, like a year ago? Why the change of heart? Anyone got the full story, or did I cross my wires?
[+] pkaye|4 years ago|reply
There was some equipment failure last year. I think it was later diagnosed as a power control unit that failed. Fortunately there was a backup set they could switch to. Little by little parts are failing with time but they are nursing it along.
[+] croutonwagon|4 years ago|reply
I think one of the primary payload computers failed but they were able to flip to auxiliary/backup. That was in July though

It’s pretty much on borrowed time. I think they spent most of that outage trying to bring the main up and gave up.

Must be fun troubleshooting something at like 400 km orbit. Heck I had to tell a lady she couldn’t wfh today because her cell data tethering wasn’t up to snuff to hold a connection to our vpn or do much of anything. She was seeing spurts of 10% loss on downstream and 200+ ms latency.

I'd love to read a more in-depth overview/summarization on how fixes were implemented for each of the sensors. Great job to the NASA team!
[+] smingo|4 years ago|reply
Would Hubble be able to resolve Webb? Or vice versa?
[+] wumpus|4 years ago|reply
Webb is at L2, so if it wants to look at Hubble in low Earth orbit, it's going to be pointing at the sun.
[+] Kye|4 years ago|reply
Making a guess based on my knowledge of photography: probably not. It's taking vast starscapes with a wide lens with a focus range (or fixed focus) made for shooting at infinity. That means the closer something is, the less in focus it'll be. Try looking at something right in front of your face. At its furthest, JWST will be at a proportional distance relative to what Hubble is equipped to focus on. Even stitching images together, it's always going to have similar focus. No amount of resolution will get past the physics of optics.

Just a guess. I could be wrong!

[+] NikolaeVarius|4 years ago|reply
Webb doesn't cover all the capabilities of Hubble. Its a "successor" not a "replacement"
