Oh man, this is great. A Spacecraft For All is an interactive video about the ISEE-3 Reboot Project, in which a group of scientists working out of an old McDonald’s crowdfunded an effort to communicate with a nearly forgotten satellite launched by NASA in 1978 to observe the Sun and chase a comet. After the intro, click on “See the Journey”…it’s well worth your time if you’re at all interested in space or science.
For instance, did you know there exists several points between the Earth and the Sun at which a satellite can orbit around, enabling spacecraft to stay more or less in the same spot for observation purposes? So cool!
