Now Playing Tracks


that turned itself the fuck around

paddled 8 miles, figured some things out that were bothering me

paid off a loan, punched the fucking shit out of another with a huge pecuniary swipe of my meaty money-making fist

and realized that i’m on the right track in a lot of ways, and that i should continue learning to forgive who i used to be in the interest of making a better future for myself

pretty decent day in the end

p.s. also moving ahead with engine swap, hell ye


The asteroid Itokawa, photographed by Hayabusa.

Itokawa is by far the smallest object featured on this blog, measuring only about 535 metres in length, and less than 300 metres in width and height.  Its surface gravity is tiny (much less than a millimetre per second squared), so the spacecraft entered an orbit round the sun that was roughly parallel to the asteroid’s orbit, here about 7km away.  So the rotation seen in the gif is Itokawa’s rotation, not the result of a camera orbiting around it.

Hayabusa later landed on the surface, collected some dust, and returned it to Earth for analysis.  Google Images doesn’t seem to know of the photos near the surface, so I uploaded most of the good ones to an Imgur album here (edit: Google Images doesn’t recognise the photos I upload to it, but searching for ‘itokawa surface’ brings up some scattered results).  I wouldn’t have guessed that a small asteroid would comprise lots of little rocks, just barely held together by their very weak gravity.  But apparently such rubble piles are common.

These salt deposits were formed during the “Messinian Salinity Crisis”, a geological event during which the Mediterranean Sea was cut off from the Atlantic Ocean and dried up (or mostly dried up), creating massive deposits of previously dissolved salts. This occurred at the end of the Messinian age of the Miocene epoch, from 5.96 to 5.33 million years ago, ending when the Atlantic again flowed into the basin.
