Mmm. I suspect you may have missed the point. It's not written in Newspeak; it's explicitly written using the only the most common 1,000 words in the English language. Almost the opposite of Newspeak, in fact.

So...

"Rapid, Unscheduled Disassembly" = "Parts fall off your space car in the wrong order."

Unfortunately, I'm afraid the basic idea behind the joke is flawed. I'm pretty sure I know quite a few people with a vocabulary smaller than ten hundred words.

Finally, the lost blueprints of Apollo … Everything we need to build a new one…  ;D

 ;D

Definitely using this comic to respond next time somebody starts a rant about the blueprints.

I wonder if he'll offer this one as a poster on his store.

He is taking the liberty to add the suffix -ing to many of the words in the 1000 most common list.  "Burning", "Landing", and I did not find "breath" or "breathing" in one list of 1000 (I did find "breath" in another 1000 word list). The word "computer" wasn't in either list I checked.

Side question: can humanity colonize space if the word "computer" isn't even in the the top 1000 most used words?

XKCD rocks!

Six Words
https://www.xkcd.com/1244/

Kind of funny considering that half the JPL is playing KSP.
For a variable Isp spacecraft running at constant power and constant acceleration, the mass ratio is linear in delta-v.   Δv = ve0(MR-1). Or equivalently: Δv = vef PMF. Also, this is energy-optimal for a fixed delta-v and mass ratio.

I also liked the rating for a Thor launcher (the precursor of the Delta family) -- one horse and three dogs!  (And the slightly less powerful Unha, at one horse and two dogs...)

Also, I happened at one time to own a 1981 Oldsmobile...

New XKCD what-if on swimming pools on the moon:

http://what-if.xkcd.com/124/

He notes that sending a decent-sized swimming pool's worth of water(135 Horses) is practical with not too many Falcon heavy launches. He does not mention oxygen ISRU though, which would make this even easier to the extent that it'd be possible to deliver the hydrogen with just one mission. I get 12.5 tonnes of Hydrogen for a 10m x 5m x 2m pool which would fit in a BA 330.

Huh. If Bigelow gets his lunar hotel running he'll need to include a swimming pool. It could lead to a significant increase in demand. I think the number of people who would be interested to pay for moon gravity swimming is probably larger than the number of people who'd want to pay to have their footprints on the moon.

Forget swimming -- I'd rather fill a dome or sealed lava tube with air, strap on wings, and fly in lunar gravity.  You'd need a pretty high air pressure to make it work, but that would be cheaper than bringing, or making, water just to swim in, I'd think...

And I always wanted to hollow out an ice asteroid, spin it for artificial gravity and figure skate hard enough and fast enough that I could perturb the effect of the artificial gravity.

Domes/huge pressurized enclosures are a bit more far term. But indeed, they offer some really interesting possibillities.

The increased payload of multicopters is one interesting consequence. could easily lift a person on the Moon (and could almost do the same on Mars). So would we see people using multicopters as the lunar equivalent of scooters? Maybe.
