I hope that I've misjudged humanity's capacity to build gigantic things!

Starship isn't built like a human, though. Maybe it's more like a Dug, whose arms are stronger than their legs. I think it's reasonable that the booster could be built to hang from the griffins, considering they already carry a similar stress while falling and there is a bulkhead nearby for the second stage attachment point. What makes me skeptical is the fact that the machine needed to grab the booster is basically a robot as big as a skyscraper, which sounds very difficult to pull off and ripe with unforseen issues.

I think the battery would be the more likely point of failure, in the cold. -
Surface fixed and rendezvous reference frames
cubinator replied to Chocolat Oreos's topic in Prelaunch KSP2 Discussion
I think I've seen surface fixed frames as an option in the Trajectories mod that calculates atmospheric entry.- 19 replies

delet this ============== Ahsoka is definitely BadS, though.

Could be salt as well. That is, if it weren't actually mint ice cream, which it totally is.

I remember being excited about Career mode coming out (now Science mode) but being on a trip and not being able to play it right away. I don't remember what version it was but I started playing in 2013.

https://www.themartiangarden.com/ I found some dirt for sale. I might have to get some. -
I can see it now: Ahsoka unwittingly force-rams Val into a wall, Val turns into spaghetti and destroys everything.

Bad science in fiction Hall of Shame

Maybe human zombies have clear hemolymph and dorsal hearts too. -
Except SpaceX's progress likely wouldn't be slowed by any change in the contract. The only thing that might happen is an unrelated, coincidental delay caused by some other factor.

Apples are generally the tastiest.

Great work! That really would be easier if Alyx would just hold it for you in the car, wouldn't it? -
Gonna have to make some changes to my Lego ISS model soon.

Short Lifetime For Nuclear Thermal Rockets In Space?
cubinator replied to Spacescifi's topic in Science & Spaceflight
That's what I guessed - that the fuel rods in a NTR would last considerably longer, lasting plenty of time for your trip to Pluto. -
Short Lifetime For Nuclear Thermal Rockets In Space?
cubinator replied to Spacescifi's topic in Science & Spaceflight
Quick google says fuel rods last about six years in a nuclear reactor*. Not sure if they would last longer in a NTR because they're not being 'used' most of the time, but I'm no expert on the physics involved. *Followed by a series of headlines about how scary and dangerous the waste is. -
I interpret it as them deciding that it is worth the additional effort to build bigger rocket boosters capable of reaching the Sun, because that is the only appropriate place to dispose of the bombs.

You just have to wonder if some strange clump of algae has wrapped itself around that thing and managed to feed off of it during all these years. -
Mars Rover Perseverance Discussion Thread

I seem to recall seeing a video of a documentary host picking up and holding a large chunk of plutonium. He was wearing only gloves for PPE. -
That tower will be made much taller, and the rocket will stand next to it for launch.
-
I think small thrusters are the simplest solution. They are included in the current NASA spacesuits and are what astronauts are trained to use in the event they end up free-flying from the space station. That's if you're in an uncontrolled spin. But if you're free floating and NOT rotating to start with, you could swing your arms or spin a tethered mass to slowly get yourself into a different orientation.
-
Of course it doesn't. We're not going to Mars for the good of 'the economy'. We're going because humans want to go to space, and we can.
-
In order to cancel any of your rotation you'd have to do something like rotate your arms rapidly, which would be really tough in a spacesuit. If you had a heavy toolbag you could swing on a tether, you might be able to use that instead. But I don't think you'd be able to cancel any really significant rotation, you'd be better off just being aware of how you're spinning and living with it.
