I wish I could do that to my software sometimes. Just bang my computer to get it working.

You can - in Javascript for example: setTimeout(function() { ... setTimeout(function() { ... }, Math.random() 1000); }, Math.random() 1000); // winning!

Too bad it’s javascript.

For those interested in learning the spectacular engineering that went into the Hubble: http://a.co/d/4kLahfW

That's definitely not what I expected to find at the link! Thanks for posting it. My father was an engineer on the Hubble, Hexagon and other reconnaissance satellites, and I'm sure he'll get a kick out of this "manual" as a gift.

While people may think that this is wasting money, I see that this these teams gain unieque knowledge and experience on how to resolve issues on "machines far far away", and if we are ever to explore/move humans to a new planet, you want THOSE exact teams as 'helpdesk' that use anything and everything to bring things back to life and operation.

This is assuming generational knowledge can be sufficently passed down to be useful in future missions. I'd assume this is quite a niche/specialized skillset they developed for this particular machine. The utility of the knowledge has a limited timeframe which may not justify education of the next generation of scientists. But regardless recording it would likely be helpful as most problems in engineerings seem to re…

We build on the knowledge of those before us. The people who invented the original programming languages are mostly gone and most of us probably don't know how to use the stuff created but future works were based off the findings of those before them and we all benefit from that.

Reading about the specs and the planned degradation of the gyros is a very interesting exercise in planned reduction of a service. They know the gyros will eventually give out and they have contingency plans around what kinds of science they can continue to do even when they're down to 1 gyro. Very impressive. I'm always discouraged hearing people say NASA is wasting money and science and that's just not true IMHO.

I think its reasonable to assume AI will be able to fix these kinds of problems in the future. They could run simulations of all the possible failures and solutions ahead of time or during operation eventually

I think the creativity and imagination required to solve this kind of problems is not really within current AI reach yet. The ability to take existing ideas and combine them in unique ways to come up with something new is very powerful, and not yet easily replicable by AI.

From this link... http://hubblesite.org/the_telescope/team_hubble/#hubbletime Each year astronomers from dozens of countries vie for precious minutes of Hubble's unrivaled view of the cosmos. A review committee made up of experts from the astronomical community determines which proposed observations address pressing scientific questions and make the best use of the telescope's capabilities. Each year more than 1,000…

Some of them might not actually need Hubble specifically. There are a fair amount of observation platforms, maybe they can get their work done on another satellite.

To some degree yes, but most of the approved observation plans have already been sifted through the "can they get this done without Hubble?" filter.

i think that's true generally of any organization. pareto -- 80% of work done by 20% of workers. there's also some other law about the work being done by the square root of the total workers.

I agree the 80/20 is true of most organizations. But producing nothing and keep your job for life as long as you show up for work is not common in private industry. On the private side, I see developers get let go all the time for inadequate work.

This is an oft repeated trope, and it couldn’t be further from the truth.

I’ve personally worked at large private firms where incompetent folks coasted for decades.

When management’s clout is measured in headcount, you get this (whether in the private or public sector)

Didn't the NSA gift NASA two hubble class telescopes with a note along the lines 'bought a ton on bulk discount and never ending up using these two before the new model was released'?

The NRO (national reconnaissance/spysat office), back in 2012. They also gave them the mirror and other components for a third. They were hand-me-downs, presumably obsoleted. Things like that always make me wonder what the current state of the art is, let alone when you look at the things like the SR-71 Blackbird, first launched in 1964 -- 54 years ago!! On the other hand then you look at things like the F-35, SLS, Zumwalt, etc today and it somehow almost seems that we've regressed technologically.

Hubble is back but nasa.gov is black. A blank black page. All because their web devs wanted (or were pushed into using) some crap front-end lib that has no fall-back for no javascript. nasa.gov's accessibility is absolutely terrible for a government website.

Having the embedded software in the sky working well is a bit more mission-critical than having the website work without javascript.
