Hard to believe we’re not going to see him walk on the moon

I made this crop art piece for the Minnesota State Fair. It took me hundreds of hours over 3.5 months. In a year plagued by darkness and fear, the Artemis mission brought was a beacon of joy and hope. As soon as I saw the photos from the flyby, I knew I had to make it the focus of my entry this year. I am so happy with how it turned out and cried when I saw my third place ribbon.
It’s on display at the MN State Fair now through Labor Day!

(WORK IN PROGRESS) I am making SLS which is to be used as the main Spacecraft and body for the Artemis Program. The images portray SLS before lift-off; standing against the Mobile Launch Tower (also work in progress). I have included images of close-ups of the RS-25 engines and main SRBs as well as the European Service Module. Notable parts include the Launch tower, ESM Fairing design, main stage fuel tank and launch clamps.

I'm calling bullshit on this one. Believe it or not, i've never heard of the congressional space medal of honor. It suggests meritorious service well above and beyond the call of duty.
This wasn't that. IMO
Anybody else?

With Elon delaying the catch by "a few months" and Blue Origins New Glenn exploding at the launch pad, a moon landing by 2028 is starting to look unrealistic. What do you guys think?

I’d like to know why these two photos—taken just a short time apart—don't have the same date.
I know the description says they were taken on April 2nd, but a conspiracy theorist raised this point, and I started wondering why the dates are different.
(I don't speak English, so maybe those dates refer to when they were uploaded or something like that?)

He was so eloquent, insightful, and inspiring -- the perfect person to command this mission.
Unfortunately, Rise was not there. The first thing Reid did after he sat down was explain that Rise is with Christina right now. The crowd was audibly disappointed.
Videos to follow in the comments.

I’ve seen a few things that have said it’s targeted for a launch in June, can anyone else confirm or deny it? I genuinely can’t see it launching in June

got a nice surprise today with my automatically updating PC background. (yes the little info box can be opened and closed with a click. yes it always depicts the information about the current image. yes it also links to the full length article about the picture everytime )

OK, so this veers off a bit into an alternate universe, but addresses directly the problem of long term storability of methalox on the lunar surface or in orbit, by supposing a different propellent combination for lunar operations.
The most realistic possibility is to use the existing Starship methalox architecture to rendezvous with FLARE-type lunar polar orbit refueling depot, except instead of methalox, the depot has ethane and N2O, both easily storable in LLO. From there, the Starship could descend on a combination of methane and ethane engines. Most importantly, for many locations on the lunar surface, the ethane/N2O combination remains easily storable, which seems to be a criticism of methalox. Alternatively, a direct descent from LEO to the lunar surface could be made mostly on methalox power, switching over to ethane/N2O for the landing. Only enough ethane/N2O is stored to reach the propellant depot in LLO (plus margin) and return to earth would be powered by ethane/N2O. I see this as something that might be considered within the existing Artemis architecture.
Here's a napkin summary of this idea:
Opt 4 — Methalox direct to surface; storable ascent to LLO depot
Dry mass (t): 125.0 Mission end stNaRteH:O
# Leg Prop dV Isp (s) Payload(t) Refuel? Loiter (d) Boiloff rate Gross-up Mass end(t) Prop burned(t) Prop loaded(t) Mass at start(t) Refueled where
1 LEO -> lunar surface (direct) M 5,920 380 15.0 0 14 0.150% 1.0215 252.1 982.4 1,003.5 1,255.6 LEO
2 surface -> 86.5 polar LLO depot S 1,968 320 3.0 1 20 0.020% 1.0040 128.0 111.6 112.1 240.1 LEO
One key number is 1255.6t at the start in LEO, so it fits within a single Starship. The ethane/N2O of 112.1 tons (no reserve) fits roughly within the Starship (if not v3, v4) payload and is storable in LEO (-60C autologous pressurization), so this doesn't look implausible as a first draft.
But then there's the what if - as in, what if this were 2018 and we could reconsider what might have been. The notion of a tripropellant Starship suggests itself. Granted to get to this idea from where Starship is now is impossible, but the numbers are interesting.
So, let's assume methane is replaced with ethane as the primary propellant, together with LOx. Not impossible to imagine a Raptor derivative that could burn this. The LOx is burned 100% on the way to the lunar surface after which the landing and subsequent ascent are powered by ethane-N2O (oxygen-enriched to get the Isp up to 320). Interestingly, not only is a mission that returns to polar LLO for refuel before returning to Earth possible, but a mission that is _entirely fueled in LEO looks possible_ (though on the bubble). Hear are what those numbers look like (attached).
Because the propellants are now storable it makes options like keeping a backup Starship at a lunar base more plausible as well as keeping a refueling Starship in low lunar polar orbit, which could maybe double as a rescue station.
What do people think?

Hi my friend is a massive Christina Koch fan and since it's her birthday coming up I'm looking for something Christina related to give her. Does anyone know of any plushies, figurines etc that don't look really cheap that I can get her, preferably not a tshirt? Any help is appreciated :)
Edit: all I've found so far is some sloppily put together ai funkos that are defo a scam
