Every time we see Saturn in the night sky, we’ll remember. We’ll smile and we’ll want to go back. 13 amazing years exploring the planet with @CassiniSaturn #GrandFinale #GoodbyeCassini #Cassini. All images are from @NASA. The blue dot is us, so small and alone in the universe. The middle photograph is the last image Cassini took. The third and fourth photos just shows off the beautiful rings.
A beautiful nighttime launch of SpaceX’s Falcon 9 (its been a big couple of days for various Falcon spaceships around the galaxy), as it took off in from Cape Canaveral, Florida, separated into two parts (the cargo was 11 communications satellites destined for low-Earth orbit which flew on to deploy a couple of minutes later), and then returned safely to the launchpad on Earth. Finally a fully reusable vehicle!!! Or in the words of Bad Astronomy’s Phil Plait “space history was made. For the first time the first stage of a rocket came back from helping boost a payload to orbit and landed vertically back at the launch site” (http://www.slate.com/blogs/bad_astronomy/2015/12/21/spacex_successfully_re_lands_a_rocket_booster_after_a_launch.html).
Then there was the hysterically snarky tweets between between competing space company’s CEO’s @elonmusk and @jeffbezos.
