Underrated comment

Yeah. Sadly the shuttle's design was plagued with flaws, including some that made it unsafe in ways that nobody realized until it had already been in service for a long time. Not having a new vehicle in development long before the shuttle was taken out of service was the real mistake, but unfortunately the SLS and its predecessor designs have had so many changes by different administrations and representatives trying to put their own stamp on things and keep the jobs programs going that it will never be able to fill the shuttle's shoes even if they eventually manage to bring the price down. Competition and getting away from cost-plus contracts, as in the current commercial crew program, are really the way forward now... The time has come. But it's still going to take those years of development, even if the future results of that approach should be better and cheaper in the end than they would've been under the old paradigm.

@@TallinuTV yes, the private sector has already brought the cost down a lot. Hopefully they get things back on track and i can one day retire on my space yacht.

There is probably no direct computer replacement available - I guess space qualified computers have moved on since Hubble was designed.

Probably very doable, you need an open cargo bay

there is no reason why the moon landing variant could not do this with the addition of a Canada arm or some other mechanism. its will already have the airlock.

@@fransdebruijn6763 an airlock will not fit hubble, also it doesnt have re-entry capability.

@@aarosundvall I think he means an airlock that can be used for space walks. Don't need to bring Hubble into the starship or back to Earth to fix it, just have to be able to allow work to be done via airlocks and a manipulator arm.

Did you refer to the repair EVA from the space shuttle point of view? If so that's one of those nice benefits of analog film, it may be old but if the master tapes are still around that same chemical film can be rescanned with something that has a higher resolution. Most other recordings (digital, various cassettes, etc) are stuck with that resolution forever (unless you count upscaling as a useful thing to do). Oh and I guess the space shuttle with such a large cargo bay could carry some nice cameras too when the space wasn't needed for payload. That's one of the reasons why older films and TV series shot in film if the original negatives are still around can be remastered in close to HD quality. However more recent but not to modern standard productions that were filmed digitally are pretty much stuck with what they used at the time.

@@darylh8657 That'd be cool, but constructing something that large on the moon will probably require much more time and work.

NASA uses old tech for just that reason - its age-hardened. They know it works and therefore its less risky than brand new untested stuff, even if the new stuff is theoretically "better" in some way. Of course that doesn't last forever. Eventually they want to build instruments that have more than 64k memory and other such limitations, and they have no choice but to try and test a new generation of technology as best they can and hope to hell they didn't overlook anything. I mean they're generally really good at their jobs so they mostly get it right, but its still a huge investment in both time and money compared to just pulling a tried-and-true component off the shelf that they already know will work for 10, 15 or 20 years or possibly longer. Its always a balancing act between new features and old reliability, and cost constraints (especially not knowing whether their budget will be up or down by a billion dollars every bloody year) means they tend to err on the side of the latter as much as they can. Commercial contracts help level that out a bit because they can buy multi-year contracts during years when Congress gives them a lot and those contracts will still be in effect the following year even if Congress screws them over, whereas they constantly have to pause or even shutter and re-start projects that run off their annual budget more directly. The downside of course being that the commercial providers are only really willing to take on contracts for things they can potentially sell to other buyers later. Launch capability is a no-brainer, and hopefully remote manipulators and EVA capabilities will join that list in a timeframe that Hubble can withstand.

Interesting enough, on the first shuttle servicing missions to Hubble they had a devil of a time with the doors for gyroscopes on the first spacewalk. They wouldn't close. The doors wont close on one of the most expensive pieces of equipment ever built, its the size of a bus, and they didnt really have any sort of ground to push against to force them shut. Talk about stressful.

Cost less to build a better and newer one, and launch it fresh than launch multiple EVA servicing operations which need to rendezvous with the telescope (very complex). You need to do all the physical diagnostics in space, on delicate electronic equipment, with a clumsy space suit on. It's not as easy as sending a TV repair team up on a rocket for a few hours then bringing them home.

It might make more sense though to develop an arm for the Starship though.

I guess another possibility is that, if on the off-chance that the side hatch can be opened in orbit, then you could dock the dragon to the IDA port that was left on hubble, then de-press the cabin and do EVAs right out of that hatch. I don't think that's possible though, or at least would require enough redesigning of the hatch to allow it to be opened in orbit, that it might be easier to just make the airlock/arm.

@@Nighterlev that is most definetly not the only reason why. many more reasons why programs or files these days are massive is because devs dont really have a size limit anymore. just look at modern video games. the devs that develope those probably never heard of file compression. These days if you code something and you need a function you import it from a library instead of writing it yourself. though most of the time that makes the program way bigger than it would need to be because libraries are usually bigger and have more functions than you need for your application. or in other words, compare the size and the memory consumption of windows 10 to the size and memory consumption of arch linux when in both cases your goal is to watch a youtube video. in arch you specifically install what you need, making your system lightweight and resource friendly, while windows comes with all sorts of shit you dont need or dont even want

Yes I remember writing assembly code in the early 80’s - TBH if you wanted smooth speed execution other than Binary there was no choice with the memory limitations. Nowadays they use off the shelf bloated routines, and cobble them together. We have gone backwards with less and less being able or being taught to eloquently code. Sad really - imagine what could be achieved now, by using less.

On the other hand if your hardware lasts this long, a failure by then should be celebrated :)

I mean id be thrilled to know my spaceflight hardware failed, if it had just spent 30 years reliably rewriting astronomy books. I mean 30 years is not even expected of a computer here on the surface.

It would be hard to make a video about that topic, because the state of the art gets older the further you get from Earth -- not just because of travel time, but also because older hardware has been more thoroughly tested and is more reliable, which is the most important feature for any hardware we launch billions of miles into space.

they have the James Webb space telescope that has been supposed to launch years ago that should be launched soon if I'm not mistaken

@@daltonpethel5697, it’s a different type of telescope from Hubble. It’d be nice to get a Hubble-style telescope, but with a more powerful and better-designed mirror as well as better equipment.

Not very simple.

Guys... why we have there 1 more chip than required? For the lolz boss!

Thanks, this is why I should write scripts.

Answer---a LOT. HST orbits around 600 KM....ISS orbits around 400 KM. The big issue here is that HST has no engines. It uses gyroscopes to maintain or adjust its position in orbit. So, then you're left with moving the entire ISS structure to the ISS's orbit....which again, would be impossible with the limited fuel on board for thrusters or from an attached spacecraft like Dragon or Soyuz.

Worse part is the difference in inclination, that’s the real delta-v killer.

The problem is, it's in a completely different orbit. So not only do you need to drag it down, but it needs a large direction change too....this could be done, just a case of doing it at the right moment when the orbits overlap, but it would require a lot of Delta-v.

Given that they're in different orbital planes, *alot.*

@Todd V. I mean it for sure could be done. Question is how many Dragons would be needed.

We needed a Freedom Space Station to build exploration vehicles, but it got bastardized into the ISS.

Nah, Starship is coming in quantity, at least one will be fitted with the proper equipment to perform routine on-orbit repairs and replacements, much better than the shuttle.

@@colinsouthern I'm pretty confident they will. Elon and a plethora of others at Spacex have the desire, the drive and the means. Starship changes everything if and when it does make it up and back in one piece. ☺

Rocket Labs have this Kick Stage vehicle... Use one to push around a TransHab with an airlock and all the parts. Must be a business model for satellite service calls. Heck, Tom Barnard did a cold gas thruster variant of a Quadcopter, scale that up and jet the parts and people over from ISS to Hubble 😊

have you done the math on the amount of delta V for a TREMENDOUS plane change?

A service mission wouldn't be impossible, but you'd go *too* Hubble not move its orbit. But there's not really a vehicle for it. Not quite Kerbal where we can just tell somebody to hop out from a crew dragon and hit it with a wrench.

@@toonarmycaptain "not trivial",... But one heck of a ride. And a potential future business market, commercial satellite maintenance.

Interesting idea. But I think the tug spacecraft would have to massive. HST itself masses ~11 tons. Inclination change alone would take at least about 3km/s of delta V.

According to Scott (who is my only source atm so ymmv), the dragon capsule doesn't have EVA capability either (would require airlocks and whatever else to allow astronauts and their massive suits to get in and out of the capsule without depressurizing the entire thing.. and I'm sure lots more requirements that make it harder than simply "a door"!) Certainly not impossible, but its definitely not a "just". There would be a lot of development and testing required to ensure safety and whatever that the existing module has simply never had to deal with. The manipulator arm is probably easier as they could (at least in theory) have it entirely external to the capsule and just bolt it on (or sink it into a trench on the outer shell or something, though that would likely require a whole new round of stress testing to make sure the trench doesn't become a weak point). No matter what way they go, it won't be easy or fast. Hopefully they can figure out something from the software end to hobble it along until we've got a proper fix ready to be deployed.

JWST will launch at end of October. If all goes well, it will take another 3 months or more to test everything. CAVEAT: they only get one shot. not able to go out and fix it if it doesn't work.

Dragon does not have an air lock. It can only dock to an already pressurised vehicle (so: the ISS).

Impossible from any practical standpoint unfortunately. The deltav required is way too high. Over 150km altitude difference and *over 20%* inclination difference. Remember on ISS we had to pick an inclination that was also possible for Russia, ya know without dropping stages on China... :)
