I heard or read a report that there is access for refueling if the possibility exists in the future.It's possible that a refueling port was added to Webb, so that some future space vehicle could be sent up to rendezvous with it and refuel it. Even if so, that would be a much more complicated feat than refueling Hubble was.
Here is another telescope scheduled to launch in May 2027, the Nancy Grace Roman Space Telescope, that should be able to improve on Hubble's work.NASA certainly has some interesting toys.

Will a big-azz rock hit the earth .. again .. one day? yep .. but that ain't today
however, today we will have a "close encounter" with an asteroid. how close? planetary "chin music" distance in cosmic terms .. a mere 1.2 million miles.
Absolutely NO chance of hitting us. But f you had a small telescope, and clear, dark skies, you could see it go whizzing by.
No worries IF you miss it, it'll be be back in a couple hundred years.
(source: https://www.wmur.com/article/close-approach-asteroid-telescope-online/38804330#) A kilometer-wide asteroid is whizzing by Earth on Tuesday, and anyone with a small telescope and access to clear, dark skies may be able to catch a glimpse.
Asteroid 7482 (1994 PC1) will pass within 1.2 million miles of Earth, which is a comfortable distance but still close in astronomical terms. That's about five times the distance from the Earth to the moon.
The asteroid won't hit Earth, and NASA scientists say this is the closest it will come for the next two centuries.
The asteroid will make its closest approach at 4:51 p.m. ET Tuesday.
Amateur astronomers may be able to see the asteroid later at night. The editors of Sky & Telescope magazine have put together an excellent guide to spotting the rock, saying it's possible to see it with a 4-inch telescope, even though the moon will be full.
Anyone who catches sight of the asteroid in a telescope should be able to track its motion in real-time across the sky.
If you don't have access to a telescope and clear skies, or don't want to go outside on a chilly January night, you can also watch the approach online Tuesday afternoon. The Virtual Telescope Project is hosting a livestream starting at 3 p.m.
By the way - where are these space rocks of planet killer size coming from? Between the Kuiper Belt and the Oort Cloud, there are TRILLIONS of candidates .. its just a matter of "time" before one breaks loose and/or gets close enough for us to see it coming.
Stuff is hitting the Earth everyday though .. we've all seen "shooting stars". No need to lose any sleep over it though -- we'll have plenty of notice and maybe even some things to defend ourselves against ELE's one day....
Very generous of them to put up a 480p version, if they play the tube right they could make way more than what ever their premium option is.here's what the Virtual Telescoope folks put on line after they tracked the asteroid. I believe this is sped up to compress about 120 minutes of observations into less than one minute.
Sorry for the "nerd dive" here ... this illustration seems to definitely answer the question I had about the "orientation" of Webb around L2.“Webb, welcome home!” said NASA Administrator Bill Nelson

I had a Celestron model .... don't recall which one exacxtly but it was a 4 incher as well.I am right there with you. I will never look at my little 4” Schmidt-Cassagrain the same. (But still love that it opens my kids eyes to worlds far beyond our personal grasp).

There are "real time" tracking videos ..

.. taking snapshots every few minutes for two hours .. where you (when they pointed out the asteroid in the "sea of dots") can see ONE dot move relative to the others. The background "dots" (due to distance from us - all probably stars) look fixed by comparison.
This depicted alignment of asteroid 1994 PC1 and Earth wont happen again for 200 years. Looks like Mars & Earth are the only two planets that need to keep an eye on this one as Mercury and Venus orbits do NOT cross 1994 PC1's
Basically same way Clyde Tombaugh found Pluto 100 years earlier .. but way less painstaking/eye-straining because the software/photography advancements since then.
Yeah, I have trouble putting gifs in here ... I see other people do it a lot so there must be a way.The virtual telescope captures a lot more cool stuff, like the James Webb

i gotta correct myself.First pictures in 6 months? If all goes well?
Can’t wait, this is so wild.
Now watch Voyager I or II Photobomb them.
(Not sure if is possible but would be cool)
