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.

space is getting pretty serious.

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.
