ISRU technology has been given two great advances:

The first
If Martian brine water is not available, methane itself can be a source of hydrogen needed to convert Mars’CO2 atmosphere to more fuel.https://www.nature.com/articles/s41560-025-01925-3

This process also produces carbon nanotubes.

The second:
Hydrogen peroxide looks easier to synthesize

Regarding the Sidus Space news release, Sidus is one of over 2,000 firms that have been pre-qualified to possibly receive a contract from MDA (emphasis on possibly). It’s the entire SHIELD program that has a cap of $151 billion, and each pre-qualified firm could possibly receive an IDIQ contract, which often translates to they receive $zero. All 2,000+ firms could have issued a similar news release; many already have. https://breakingdefense.com/2025/12/mda-adds-1086-firms-to-its-shield-pool-for-golden-dome-related-tech/

I’m confident that a Hubble servicing mission will happen. Until there is another generation of orbital optical telescopes ready to go, it simply makes financial sense to keep the old girl functioning at her peak.

Re: Hubble – I reeeeeeeally hope they will upgrade, or at the very least, save Hubble with some more giros.

I suppose now that Isaacman is officially the head of NASA, he will not be one of the astronauts going to Hubble. Then again, he is the boss.

Either way, a mission to Hubble is necessary. Yes, there are, and will be, better space telescopes. The heritage of Hubble will live on for centuries. Keeping it going a little while longer is simply a good idea.
