It's just a start and needs tweaking, but here's some non-planar, conformal #3dprinting of thermal protection system materials for a #NASA project at re:3D using New account: @FullControlXYZ. re:3D

You know I'm getting serious about debugging at re:3D when I haul out the 'scope. Don't mind the spaghetti wires - they got cleaned up once the problem was solved.

My phone wanted to automatically tag this as #food instead of #supercoolNASAstuff that might one day be applied to heatshields using specialized #3dprinters for protecting spacecraft during EDL. re:3D

Unfortunately, I don't know to whom I should attribute this, but I found it in a 2012 #NASA Thermal and Fluids Analysis Workshop (#TFAWS) presentation, and it rings so true to me:

Sunday morning experiment trying to cool air with a Peltier. I could improve the design, but the low thermal mass of air is a real killer. I knew that going in, so this was more of a 'for grins and giggles' project.

I know we're all here for the #JWST images, but I have to pivot for a moment and say that this here is bullshit. Sorry to see this happening. Clear Creek ISD superintendent hammered by anti-CRT parents announces resignation houstonchronicle.com/news/houston-t… via @houstonchron

Lovin' all the additions and upgrades to the #ISSMimic model. I know there's a lot of love on the Mimic team for the SASA antennas, but I gotta say that they're not as iconic as the Ku-band antennas. It looks like some upgrades to JEM since I last saw it too!

Hey #space Twitter: I see numbers in the $2600/kg range to put a payload into #LEO. Does anyone know how much it costs (will cost) to get into lunar orbit? Maybe Eric Berger, Everyday Astronaut, or Jeff Foust has a reference?
