Reply to NASA And SpaceX Consider Daring Plan To ‘Reboost’ The Hubble Space Telescope by aureliamachiavelli
What's the lifespan on Hubble looking like?
Its hardware is already showing ware and some stuff has shut down entirely
I'd like to see its mission continue but at some point it's just going to die.
A refurbishment of some of its equipment would probably help if possible, like changing its Reaction Wheel systems that have broken

This one involves Isaacman/Polaris right? It makes sense if you want to start training private astronauts to start with a customer who knows how to do it and can transfer you the required knowledge.

Now that would be cool. Let’s hope the study is a success.

Yea but you know it won't happen that way. It'll be a gully washer and mess up more of CA if that's possible.

At least another one is forming to the left of that giant.

It's important to understand "Average" weather for a region is a passing moment as it moves between extremes. Two areas can have an average of 70F, but one goes from 40F to 100F in a day, and the other goes from 65F to 75F.
10 years of Southwestern US weather is approximately six years of drought, two years of flood, and two years of decent. The drought ends with floods.

Here is a loop showing the anticyclone in action its from NOAA directly.

Helion has had some success with Deuterium / Helium 3.

If vents exist on the seafloor of Enceladus, and all the methane is from life in vents, and then that life survives the long journey to the surface through the ocean and ice, and then survives massive depressurization when it hits vacuum, and then doesn’t get murdered during the still high velocity flyby, then it only takes 100 such flybys, which is huge number.
Some papers are worth writing because it’s good to crunch some back of the envelope numbers, but we don’t always have to take them seriously…

Mostly. They've already proven it too. Right now they are building their next generation reactor that will actually produce power. The last version demonstrated the release of energy correctly.
The one step that will have some consequences is creating the helium-3. The problem with smashing two deuterium atoms together is that neutrons can't be constrained by a magnetic field. That reactor will likely need more maintenance as a result. We could try to capture the neutron with some sort of modulator. The problem with beryllium is that it's extremely rare and typically has uranium inside it in low quantities. This uranium accumulating neutrons will create radioactive waste.
The second process can be completely contained with a magnetic field.

As a recipient of some of this water, I hope it keeps coming! We do desperately need it in the SW US.

essentially clean energy then right? Doesn't seem like it's too far fetched.

What California needs is widespread rain catching to reverse desertification. Tearing up all those sealed parking lots would help. Reintroducing the beaver would be a great idea. Cities should dam sluices to slow runoff.
In the mean time damming any dry wash would help. I would recommend digging a ditch to catch runoff on the lower end of your property. Put the dirt you dug out downhill of the ditch.
A lot of people have forgotten that there was a huge lake in Southern California a century ago, Lake Tulare. Poor land stewardship has turned the former lake into a desert.
