NASAs Juno Gives Starship-Like View of Earth Flyby – NASA Jet Propulsion Laboratory.

The Juno spacecraft took this low resolution but still really cool video as it flew past on Oct 9. Juno used Earth for a so-called gravity boost, though it would be better called an angular momentum boost. It’s a great bit of perspective for those who think the Moon is pretty big and close (it is, compared to other things in the solar system, but not compared to our everyday experience!)

Today, the Cassini spacecraft will take an historic image of a Saturn eclipse, with the Earth in the background. Carolyn Porco and Astronomers Without Borders are celebrating by hosting The Day The Earth Smiled. visit http://astronomerswithoutborders.org/projects/the-day-the-earth-smiled.html to find an event near you.

Don’t forget to smile and wave at Saturn from from 21:27 to 21:42 UT. That’s 5:27 – 5:42 in Ann Arbor, where Saturn will be about 25 degrees above the southeast horizon (a little more than the distance if you spread your hand out at arm’s length.)
