 | so nasa is about to crash a spaceship it flew 7 or 11 million miles on an ion drive into an asteroid to alter its
 trajectory; it's already deployed a little data relay drone
 to record the results...
 
 ...and i'm like: wait, ion drive? that works now? it
 turns out i missed a step there, deep space 1 used an ion
 drive. first apparently after... hall effect? that can
 actually move shit?
 
 but, really, same with ion drive. it's worked for decades,
 but it was never practical -- trying to move a boat with an
 ant fart, except the ant never stops farting, and you
 gradually speed up. deep space 1, that this makes sense now;
 that thing has taken its time. i don't really understand how
 to translate N*S to a coherent picture, but i do see from
 some stat chart that it's about twice as efficient for the
 same KW/h, and then nonlinear... bump it up from 5 to 7 KW/h
 and it's almost an order or magnitude stronger
 
 and you know what? it looks exactly like you'd want
 an ion drive to look. very gorgeous and sci-fi
 
 then i read: 2027 we will launch some shit with better ion
 drives to shower down a grip of drones on jupiter's moon
 titan circa 2034. and they'll obviously have cameras
 
 just kind of like, i hope i live long enough to see that.

 | they got some really good pictures. mad boffins even managed to time it so... last frame on the feed they only have about
 1/8 of the image, the first 1/8 rows of pixels, rest is red
 because that's when it blew up
 
 and this is like someone repeatedly taking polaroids, and
 madly jamming them into a fax machine in lieu of a
 livestream, from seven million miles away. i feel compelled
 to say this because i'm not sure anyone will even notice:
 they completely nailed the knife edge of the timing of when
 the opted to transmit images to the point where the last
 frame is literally interrupted by impact and... this thing
 had no sensors, just a camera. that is some damn fine coding
 work

 | my favorite thing about space is how little we know. even with all this money, talent and effort put in we are not
 even scratching the surface it seems. the fundamental
 questions are still unresolved even with all this technical
 progress. how can something come from nothing? is there
 soemthing smaller than preons? how large are the large scale
 structures of the universe? what is consciousness? we don't
 even have a proper definition for "life"
 
 I rather like human experience being like this

 | ion drive works, as far as i remember there just hasnt been a mission suited for a test drive. were not exactly putting
 all our efforts and money in space right now which
 absolutely understandable. way to go now. love the asteroid
 altering efforts. this might come in handy some time. of
 course the biggest rock right now is climate change and
 water/soil management. but it took more than one rock to
 take the dinosaurs down too, so it would be good to be able
 to dodge that bullet.
