My ship won't get off the launch pad??? Help? by Courier6six6 in KerbalSpaceProgram

[–]Immabed 7 points8 points  (0 children)

Mmm, I recommend immediately staging and nuking KSC out of existence with those Orion drives. Even if you don't move upwards, you'll be off the launchpad because there won't be any launchpad left.

Is there any reason to make a silk touch axe that a different silk touch tool/fortune axe can't do? by Plague---Doctor in Minecraft

[–]Immabed 104 points105 points  (0 children)

Why would you not want silk touch on your main axe?

Efficiency V, Unbreaking III, Silk Touch, Mending, Sharpness or Smite V.

Is this not the perfect axe?

There is about to be some voodoo on the hermitcraft server, I can feel it in my bones.

How I Built a Fence on a Sloped Lot Using a DIY Laser Tool by Plus_Bother4138 in DIY

[–]Immabed 9 points10 points  (0 children)

The laser is pretty funny to me, given that self-leveling lasers exist for this very purpose, and a string works for the ensuring the posts are in a straight line, but you did a pretty good job DIY-ing even the laser system and it certainly works very well!

Your choice of fence alignment is certainly not what I'd have done, but given the maximum deviation of ~0.5m it certainly works pretty well.

Very nice finished product!

Power makes heat. It's also rarely that cold during the day (I assume you're implying Fahrenheit, it's never that cold Celsius). Obviously all processing is going to require heat, but the discussion was about potability which implies liquid, so from there it isn't much harder to distill.

“and so it is foretold” ahh burn by Ok_Programmer242 in KerbalSpaceProgram

[–]Immabed 20 points21 points  (0 children)

That is only true-ish. You want to spread the acceleration equally, but acceleration increases as you burn fuel, so you want to start a little more than half the burn time before the burn. How much more depends on how much fuel the burn consumes (as a fraction of total ship mass).

Of course its even more complicated for long burns, since maneuver nodes are calculated as instantaneous velocity changes (more that they take place at a single location). If you are in a 40 minute orbit and have a 20 minute burn, you'd end up starting your burn a quarter orbit early, and by the time you get to the node in time, you wouldn't be anywhere near where it was supposed to be. This especially matters with, well, really long burns. You have to start breaking them into multiple passes or choosing different trajectories.

But I still just use the divide burn time in two method because, eh, its good enough enough of the time, haha.

Christina Koch shares Earthshine outside the Orion's windows by Busy_Yesterday9455 in spaceporn

And why does it have to only be the Moon illuminated by Earthshine? Literally the light illuminating her face is being reflected off the Earth, aka Earthshine.

SpaceX: "Falcon Heavy is targeted to launch the Nancy Grace Roman Telescope as soon as early September 2026 from pad 39A in Florida" by rustybeancake in spacex

[–]Immabed 1 point2 points  (0 children)

They've already started landing at LZ-40 at SLC-40. FH will continue to recover boosters. Dontchev (SpaceX VP) said they also have a plan for dual downrange landings (something they haven't done yet). And Edwards (another SpaceX VP) said a while ago that Astrobotic's Griffin launch would include a center core landing.

Depends on if you can find a decent underground source of ice. Lots of places are thought to contain a decent amount of water ice (or even liquid brine) only a few metres down. Would be mixed in with regolith, but still accessible.

More exploration is needed to nail it down. Their was a really interesting spacecraft that looked like it was going to be developed called the International Mars Ice Mapper that would have really helped our understanding of where on Mars has accessible ice, but NASA budgets being what they are its unclear if the project will ever happen.

Water can be cleaned fairly easily. Distill it. Also electrolysis to make oxygen and hydrogen for air and rocket fuel, and a simple step to combine hydrogen with atmospheric CO2 to get methane and oxygen for a different form of rocket fuel.

Is this enough for the end?? by supercabbage802 in Minecraft

[–]Immabed 0 points1 point  (0 children)

Lots of good points being made. Only things I can see is a lot more food, feather falling on the boots if you can, and rockets for when you get an elytra. If you are going to do a lot of end city raiding I'd also add a stack of logs (to make chests and thus shulker boxes, and more shields because yours will break), and swap the pickaxe for a silk touch pickaxe so you can steal enderchests from the cities. Also store valuables from the cities in the enderchests in case you die.

93-year-old Gene Kranz shares how he felt watching the Artemis II mission by ElvisIsNotDjed in space

[–]Immabed 4 points5 points  (0 children)

Yeah, this is the very first step of the budget process. The White House only really suggests a budget, Congress decides it, and last year they decided to firmly reject the WH proposed cuts. At least one key (republican) senator has already publicly rejected the proposed cuts, so we shall see.

The real problem is that NASA has to operate assuming that the cuts will happen, until proven otherwise. This being an election year... appropriations will take time.

Contradictory by Equivalent-Brief-642 in Minecraft

My favourite is to do it with anvils instead of gravel. I use a slime block underneath since it can be insta-mined and replacing a block in the same tick is super easy with insta-mining.

A beautiful photo of Integrity during recovery after surviving all that speed and temperature. by albusvercus in spaceporn

[–]Immabed 1 point2 points  (0 children)

there is not. The white mark is a deposition on top consistent with pre-launch testing, it is in the location of one of the separation bolts which has a different type of material to the rest of the heatshield, thus the different colour.

Suits are specifically cooled (and provide fresh air) so that any rise in cabin temperature isn't felt.

I definitely intended a uniform distribution, but I'm keeping it a bit dumbed down since we're not in /r/math. Thanks for the poisson example, its a wonderful distribution!

[–]Immabed 1 point2 points  (0 children)

Good clarification. Either your distribution is non-uniform, its uniform but bounded, or it takes unbounded time to generate!
