Exogeology ROCKS! Episode 12

Posted by Zoe on 29th November 2014 in Main Page

In this episode, we meet Dr. Dante Lauretta, Professor of Planetary Science at the University of Arizona and Principal Investigator for the OSIRIS-REx mission.

I’ve talked about the OSIRIS-REx mission before, and it’s one of the coolest things going on in exogeology: they’re going to send a spacecraft to an asteroid and bring back a piece. Wonder what it’s like to be in charge of all of that? Watch the video below to find out!

For more information, check out the OSIRIS-REx website, Xtronaut’s website, and the 321Science! videos.

321Science Presents: Asteroids Fact vs. Fiction

Awesome news: the countdown for the OSIRIS-REx asteroid sample return mission has begun, and it’s now only 996 days until the beginning of the launch window!

Want to know more about asteroids and sort the science facts from the science fiction? The 321Science team is here to help with a video to illustrate the difference and answer a few questions about asteroids.

I’m incredibly excited about this video, which I helped to make! It was interesting seeing it go from script to numerous drawings to super-cool final product. I drew a couple of scale bars and small asteroid, placed a couple paper planets, and did a few miscellaneous other things. Also, keep your eyes peeled for a certain spaceship from a long time ago in a galaxy far, far away…

The Search for the Unknown

As I said before, part of being an exogeologist is getting to explore! From the bright Sun and its flares, to the outermost reaches of the Oort cloud, exogeologists get to see it all! The most exciting part is discovering new things about unexplored places.

Moons are some of the most diverse objects; some are like planets with volcanoes and atmospheres, and others are like asteroids with odd shapes and cratered surfaces. Titan has a thick and hazy atmosphere, which just makes me wonder, “What’s down there?”

Exogeologists like myself decided that Titan was a good place to explore. The Cassini-Huygens mission was and is set to explore and study Saturn and Titan. The Huygens lander detached from the Cassini spacecraft and landed on Titan. It found that there is water ice on Titan, the atmosphere is made of methane and nitrogen, and there even seems to be an underground ocean of liquid water! How cool! Literally, because Titan is so cold being so far from the Sun.

Speaking of being cold and far from the Sun, exogeology is also used for studying Kuiper Belt objects, or KBOs. The most famous KBO is Pluto, the famous dwarf planet. Just let me call it a dwarf planet for the purposes of this one blog, okay? :) Pluto and other dwarf planets are mostly made of rock and ice, like asteroids. We don’t have many good photographs of Kuiper Belt objects, so that’s one thing that I’d like to do in the future: take pictures of KBOs.

The most mysterious places to see are exoplanets, planets orbiting other stars! There are planets of all shapes and sizes out there, and exogeologists are finding more all the time! It rocks that there are other solar systems!

No matter where you look, you just might find something new and exciting! Exogeology ROCKS!
