Starship Flight Test IFT-2 Patch pre-order

On November 18, 2023, Spacex once again tested the full-stack of their super-heavy booster and starship. This time the test was much more successful despite the destruction of both flight components. The 33 Raptors successfully lifted the stack to the point of hot-staging where the Starship stage successfullly staged and boosted into a sub-orbital trajectory before breaking up over the Caribbean. This patch depicts the dramatic stage separation as the vacuum Raptors ignite. The booster stage depicts the unique and dramatic engine cut-off order of engine shutdown just prior to hot-staging. The order is depicted in colors from warm to hot. The patch will be 5 inches tall and expected shipment will be late December or early January due to the holidays. This is the planned release, some details may differ in the embroidered patch due to limitations of embroidery:

We just returned home from 30 days of RV touring in Utah. The last 5 days we had an extra passenger. This is Chinle, the scrawny cat who adopted us at a Provo RV park. She's about the best darn cat you could imagine. We named her after our favorite geological formation found in Utah. The Universal Cat Distribution system is real. #CatsOfMastodon #vanlife #catdistributionsystem
I'm not an astrophotographer, but when I'm at a dark sky site and there's a comet, I take a stab at it! This was taken from a sand dune in the Coral Pink Sand Dunes state park in Utah. #CometNishimura #astronomy
This is the original. I had a similar blue filament for the trusswork, but it kept clogging so it's in the garbage.
This build took a lot longer than I expected with endless printer failures. This is based on the ESA/NASA Spacelab 1:50 model built by MBB/ERNO in the early 80s or late 70s. It features removable experiment racks and a detailed experiment pallet. #3dprint #nasa #3dprinted
I printed a Starship HLS to mount on the 1/100 booster. It's pretty neat because the base can be swapped from launch mode to landing mode depending on how I want to display it. I printed it in PLA so the small legs will probably sag, so I might have to print them in a more durable material. Hard to believe Artemis III is a year and a half away.
Lightning is rare in #seattle, so despite warnings from the NWS, when it roars the photographers go outdoors. I saw lightning on the Eastside, so I bolted for Kerry Park hoping the storm would pass behind Seattle's skyline. It was waning by the time I was in position but there was one stroke that made it all worth it. #lightning #wawx #weather
Aurora chasing is humbling. The anticipated impact held off nicely until just after midnight local, which is awesome, but that dang Bz stayed positive with a vengeance. No aurora photos, but I did get some star trail photos. It was so quiet on the Waterville plateau (WA) that the subtle ringing in my ears was like noise. #auroraborealis #northernlights
Finally done printing the Starship stack and it’s no joke. It took about three weeks to print and 2kg of filament. The Saturn V is in the same scale: 1/100. I still have a hard time wrapping my head around how either of these left the ground full of liquid fuel. It boggles the mind. Then to see Starship actually cartwheeling?! Absolutely incredible engineering from both eras. Stay in school kids. #spacex #starship #apollo #3dprinted
I designed these Starship TPS tile drink coasters this weekend for fun. They’re based on the images of some tiles that people have found washed up after Starship was terminated over the Gulf of Mexico. #spacex #starship #3Dprinted
