Comic and Space Game

Are you reading xkcd? If not, you would probably enjoy it!
A lot of xkcd's comics are space-related. Here are just a few:

https://xkcd.com/2469
https://xkcd.com/2804
https://xkcd.com/2258
https://xkcd.com/1878

And then there is "Escape Speed". It looks like a regular comic, but it's a playable space exploration game! Launch the ship from the tiny planet, and get going fast enough to orbit before your engine dies. When your engine recharges, thrust out into the universe. It's enormous! You can literally explore for weeks. (Hint: Most of the messages on the planet called "Origin" are true.)
