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.
The UMN Institute of the Environment’s Sustainability Education program hosted a showing at the Bell Museum of “Catching the Sun” “a 2015 documentary film on the growth of the solar power industry. Directed by Shalini Kantayya, the film features portraits of diverse personalities and their roles in the transition to solar power” (https://en.wikipedia.org/wiki/Catching_the_Sun_(film)). While there were other events associated with the showing and even a Q & A with the filmmaker Shalini Kantayya after the film, I was only able to see the film. Its a great film stressing the importance of the growing solar power industry. You can learn more about the film here: http://www.catchingthesun.tv/
The Supermoon was not looking very super when I saw it around 830pm (see photo) and then later around midnight. Bright, very bright, but just an average size. Not that there is anything wrong with an average moon, but sometimes I think it would be much nicer to have a few moons in orbit. #supermoon2016
I tried the new Virtual Reality lab in the library today. It was amazing. I figured it would be like some hokey video game, but it was so lifelike. In one game/simulation or whatever they are called, I was in the mountains and looking over the edge of a cliff and was told to walk off. Even though I knew I was in the library and that there was ground below me, I just could not walk over the cliff. Apparently very few people walk over the cliff. The human sense of self preservation is apparently very strong, even in the VR world. Besides the mountains with the cliff, I was also able to see the rover on Mars, visit an English country church, walk the mountains of Nepal, and visit a few other ones.
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.

Tonight is the blood moon aka super moon aka #SuperBloodMoon aka eclipse. It wont happen again until 2033.
Here is a bad photo of a cool eclipse taken with my iPhone 5s. I also saw a bunny outside not watching the eclipse. Its 71 degrees with a light breeze. Winter is coming, so enjoy the weather while we can.
NASA’s New Horizons spacecraft has finally reached the planet formerly know as Pluto (now considered a icy dwarf planet). New Horizons left Earth back on January 19, 2006 and finally arrived today!
Here is the blurb from the NASA fact sheet:
New Horizons launched on Jan. 19, 2006; it swung past Jupiter for a gravity boost and scientific studies in February 2007, and is conducting a six-month-long reconnaissance flyby study of Pluto and its moons that started in early 2015. Pluto closest approach occurs on July 14, 2015. If NASA approves an extended mission, the spacecraft could head farther into the Kuiper Belt to examine one or two of the ancient, icy mini-worlds in that vast region, at least a billion miles beyond Neptune’s orbit. Sending a spacecraft on this long journey will help us answer basic questions about the surface properties, geology, interior makeup and atmospheres on these bodies…
Generally, New Horizons seeks to understand where Pluto and its moons “fit in” with the other objects in the solar system, such as the inner rocky planets (Earth, Mars, Venus and Mercury) and the outer gas giants (Jupiter, Saturn, Uranus and Neptune). Pluto and its largest moon, Charon, belong to a third category known as “ice dwarfs.” They have solid surfaces but, unlike the terrestrial planets, a significant portion of their mass is icy material. Using Hubble Space Telescope images, New Horizons team members have discovered four previously unknown moons of Pluto: Nix, Hydra, Styx and Kerberos. A close-up look at these worlds from a spacecraft promises to tell an incredible story about the origins and outskirts of our solar system. New Horizons also will explore – for the first time – how ice dwarf planets like Pluto and Kuiper Belt bodies have evolved over time” (http://www.nasa.gov/sites/default/files/atoms/files/nh-fact-sheet-2015_0.pdf).
Here is New Horizons and its path (images from NASA http://www.nasa.gov/sites/default/files/atoms/files/nh-fact-sheet-2015_0.pdf):
Here is wonderful new photo of Pluto released today (image from NASA http://solarsystem.nasa.gov/multimedia/display.cfm?Category=Planets&IM_ID=20233)
Also traveling with New Horizons are nine objects – such as a stamp and the ashes of Clyde Tombaugh – who discovered Pluto, are in a 2-inch aluminum capsule inscribed with these words: “Interned herein are remains of American Clyde W. Tombaugh, discoverer of Pluto and the solar system’s ‘third zone.’ Adelle and Muron’s boy, Patricia’s husband, Annette and Alden’s father, astronomer, teacher, punster, and friend: Clyde Tombaugh (1906-1997)” (http://www.timescolonist.com/astronomer-s-ashes-nearing-pluto-icy-world-he-discovered-quarters-stamp-also-on-spacecraft-1.1997909?utm_content=buffer9141e&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer#sthash.1OVsDst1.dpuf)
Needless to say that then NASA connected to New Horizons (I was watching live online) to say that it was working the Internet, Twitter, and NASA went a bit crazy!
The live signal can be seen here: http://eyes.nasa.gov/dsn/dsn.html
