Notes
When I went out form my run this morning, Venus Jupiter & Mars were nicely lined up in the pre-Dawn darkness; Mars, being the smallest and faintest of the three
I realized then how fucking FAR away Matt Damon/Mark Watney would have been in The Martian, if it had really happened
Comprehending the vastness would have driven me insane, if I was in that situation. I bug out a little just being in a boat over the horizon
