The booster is ~70 meters tall or ~230 feet.

The doctor says something in a stem tone

!keming@lemmy.world moment?

a man described in the medical literature who developed a growth the size of an orange. Yet because it grew very slowly, the man’s brain was able to adjust, shifting memories elsewhere, and his behavior and speech never seemed to change—even when the tumor was removed.

Wow, that’s wild.

Happy cake day!

At first one half of my thumb was entirely numb, and over the course of well over a decade I’d get pins & needles as bunches of nerves would finish regrowing, except attached to random channels in the nerve bundle, so my brain had to completely remap all those signals to what they actually meant.

It felt super weird because hot, cold, pain & touch were all mixed up, but eventually my brain sorted them out.

Wow, that’s fascinating. Thanks for sharing your story.

Too soon.

reusing as much of the 1970’s shuttle tech as they can

And reusing the tech, but not the hardware. NASA are throwing four RS-25 shuttle engines (some of which flew multiple shuttle missions) into the ocean with every SLS launch.

Do we? It’s already years behind schedule, billions over budget, and doesn’t really have a use beyond Artemis. Also, the Exploration Upper Stage (one of the major planned upgrades) is being developed by… Boeing.

He’s definitely earned a break though :')

Also reusable, like Falcon 9.

CEO of SpaceX alone to do her thing

COO? CEO is Musk, COO is Gwynne Shotwell.

Sooty exhaust from RP-1 and aluminum oxide particulates from discarded upper stages will not be a problem with Starship.

Starship uses methalox, and the upper stage is designed to be reusable.

SpaceX is years behind schedule for delivering crewed space flight to NASA

You are a few years behind the times yourself. SpaceX first flew crew to the ISS in 2020, and have flown 8 more crewed missions for NASA since then, as well as a few private missions.

Boeing (the other commercial crew contractor) has yet to fly a single human :)

Piracy is pretty much the only way the original Star Wars movies are still available.

“I am altering the movie. Pray I don’t alter it any further.” - George Lucas, probably.

A couple months ago, I didn’t buy a cheap Blu-ray drive and did not download MakeMKV. Since I did not do this, I can’t report on how great it is.

Why are larger propellers quieter? Does it have to do with the rotation rate required to generate thrust?

Yeah, I heard about it on a podcast a few weeks ago, but didn’t see a video until recently.

Paperclip maximizer: Stone wall edition.

Like electric model airplanes and drones, but larger. Battery energy density is not high enough (yet) to electrify long-haul jumbo jets, but we’re beginning to see the electrification of small short-range aircraft.

If you want to watch top quality unbiased science content, there’s “smarter every day”, “veritasium” and “3blue1brown”. They’re all great, I highly recommend them all.

Add to that any and all of Brady Haran’s channels: Numberphile (maths), Periodic Videos (chemistry), Sixty Symbols (physics), Deep Sky Videos (astronomy)…
