I simply read that the Hubble Place Telescope is plan be refurbished one endure time,. . . ?
Its substitute the James Webb Place Telescope; Will it be constructed as a one shot plan or will it be developed to be serviced from time to time?
Good considering the tests that were erudite servicing the Hubble, wouldn’t it pedestal to cause that if the JWST were developed to be serviceable, wouldn’t it be pragmatic to simplify certain aspects of its components as result that servicing & substitute could be preformed by a robotic service drone?
NASA it it seems won’t have the ability to do the maintenance when and if the need is required. Which leaves the Astronomy Interests of those interested pretty much up the proverbial “creek” with the rapids on the horizon (allows pray it isn’t the crest of a waterfall).
Possibly where servicing ability is required, would NASA think about building a Mini Shuttle for a crew of 2 or 3, for the out of ordinary purpose of servicing orbital platforms?
Either Crewed by Humanoids or an complex robot, a servicing ability is definitely needed.
If we’d that ability to service orbital platforms, suppose of the potential.
Instead of having hulking multi-tonnes of extinct or dying satelites in geosych orbits. Objects with the concrete and definite potential of being navigational hazzards & potential to do sedate and serious damage to presently operational satelites if they were broken up from casual collisons with every other or the numerous meteor showers we get for granted.
Why not spare the potential for waste, by having the capabiltiy to service and extent the op. Existence of extant satelites?
I’m certain the Tele Corporations who use commercial satelites are concordant to do payment through the nose to hold their marketshare viable.
And Clean Science for Humanity might suffer fewer the indignity of losing a science platform when its usefulness is no longer conventional and limited to how long its batteries will endure or a minor brief-circuit might cause a loss of an essential component.
Departure science at the clemency of the after that project – IF – the funding is t

Sounds like reinventing the wheel to me. Space shuttle serving HST worked just fine. I would think it will continue to work for JWST.
It might even be easier with JWST’s retractable mirrors.

“NASA has also been considering adding a grapple feature so future spacecraft might visit the observatory to fix gross deployment problems, such as a stuck solar panel or antenna. However, the telescope itself would not be serviceable, so that astronauts would not be able to do things such as swapping out instruments, as has been done with the Hubble Telescope. [3] A decision on the grapple feature is expected in 2008. [4][5]”
In short. . .
If it fails to deploy, they can probably repair it once, but that is it. Once it’s in its final orbit, it will stay t
You have to keep in mind that the Hubble upgrades and repairs over time could have paid for three new Hubbles. People have learned a lesson from that. Not to mention that it is not worth risking human life for something that should not be necessary in the first place. Look at the Mars program. No upgrades needed and the probes and instruments work just fine. Look at Cassini-Huygens. That’s how you do it! If you need/want to learn more, you send a new instrument using all the knowledge you have acquired with the previous one.
When Hubble was conceived, our focal plane array technology was not particularly advanced, so we could make it more sensitive by swapping out instruments.
These arrays have improved over time and now any replacement would bring only tiny incremental advantages over the first deployed version. Unlike with Hubble the payback does not justify the cost. Not even close.
The mini shuttle will never be built. I think for now people had enough of space plane technology.
It turned out to combine the worst of both worlds in the most marginal of design envelopes. Not everything that looks cool works well. This one definitely didn’t. Just ask the families of the dead astronauts.
A servicing facility is not needed. Care in the initial design and manufacture, however, is.

Hubble will be serviced on more time.
JWST is to be launched on an expendable rocket as one complete unit not designed for in space maintenance, although I did hear they added a docking port to the design recently.
But JWST will not be in low Earth orbit; it will reside in an orbit about 1. 5 million km (1 million miles) from the Earth. That is 4 times as far away as the Moon.
The existing Shuttle could never reach it, although the new Orion could.
