Looks like it. Aurora - 30 Minute Forecast | NOAA / NWS Space Weather Prediction Center
actually, another predicted spike around 4am utc with current models.

Well I'm assuming everyone has seen this? In a way I'm glad since there is a lot going on this weekend anyway RE: Superbowl but still sucks cuz I want people on the damn moon AND MARS before I croak!

NASA just delayed the Artemis 2 moon mission because its giant rocket has a leak — we've seen this before
The agency had been eyeing Feb. 8 for the historic liftoff. Now, it's no earlier than March.

Yeah about that...
I think its just them saving face for their beyond optimistic original target dates. I know somewhere else here I said SpaceX wasnt going to Mars before mid 2030.

I'll admit that Elon captured my imagination on this Mars thing, but the more I learn about it, the more it seems like the idea of a self-sustaining colony on Mars is not possible and certainly not possible anytime soon. It's also not a great plan as far as a "backup" for humanity to go on after the destruction of earth when the Mars colony is about a hundred million times more likely to get wiped out than the earth one. A moon base sounds cool though.

Realistically a moon colony always made more sense - Mars does have a few advantages (atmosphere even if thin and probably more water), but you need to prof of concept a lot of this sort of thing and a moon colony is a good way to do that since a lot of that same technologies have crossover. Plus if shit hits the fan, help can arrive in days rather than months
The only really viable non-earth option for a self-sustaining colony is Titan, but it’s too far away and would require massive leaps in propulsion technology to make it a real option

The moon is even less viable than mars. No water, 2 week long nights, high radiation etc.
Thinking you'll have a self sustaining lunar outpost in 10 years is beyond smoking crack. They don't even know if they're useful deposits of water in the shadowed regions. I think it will eventually be the industrial heart that powers solar colonization but right now there are some massive issues and unknowns to long term habitation.
Mars is an infntely better target for colonizing. Only downside is travel time.

Moon really depends on how feasible it is to extract water from the southern crater. If that is no go, it sort of kills the prospect of a colony of size.
Titan has easily accessible water and methane/hydrocarbons in massive quantities, thick atmosphere means pressure differentials aren’t as big a concern and also grants additional radiation protection, and lower gravity + thick atmosphere means air transportion can occur.
You’ve got everything you need to make oxygen, water, fuel, power generation, and even creating polymers/plastics once you process raw materials on site. Even wind turbines would be a viable option for power generation (although you’d probably still want nuclear for reliability)
Like I said, biggest negative is it’s really really far away. Transit times would be measured in years

Plus you can always divert objects in the oort cloud to intentionally crash in places you want to become viable. Many things are possible with long term thinking with even modern tech. Biggest problem is getting out there and investigating objects to figure out what chemical processes would be available to us.
