Posted by Zoe on 10th August 2013 in Geo Party, Main Page

This past week marked the beginning of the second full game of Zoe’s Geo Party!, starting with a category on Crater Lake National Park. Filming here was a unique experience—it’s not every day you see a lake in a caldera. Crater Lake was quite picturesque. It was also very cold, very beautiful, and very blue, more than you can even see in the videos.

Exogeology ROCKS! Episode 9

Posted by Zoe on 11th June 2013 in Main Page

Last month, I went to the last couple days of Spacefest, where I got to hear lots of interesting people speak and even got to interview a couple of people. Today, we meet Emily Lakdawalla, the Senior Editor and Planetary Evangelist for the Planetary Society. In this episode of Exogeology ROCKS!, we talk about where we should explore next in the solar system, landing on Titan, why communication is a useful skill, and much more. I liked hearing about how you have to be creative to be a geologist. Watch the episode below!

Exogeology ROCKS! Episode 6

Posted by Zoe on 17th October 2012 in Main Page

Woo-hoo! I’ve just finished the sixth installment in the Exogeology ROCKS! video series. The first five can be seen here.

In Exogeology ROCKS! Episode 6, we meet Dr. Cynthia Phillips, a planetary geologist for the SETI Institute. She tells us about some interesting worlds in our solar system including Europa, Io, and Mars, how to use images to study them, and much more. I particularly like her stories about her funniest and most exciting experiences as a planetary geologist.

Speech on Why Exogeology ROCKS!

Posted by Zoe on 28th July 2012 in Main Page

You’ve heard that exogeology rocks, but just what is exogeology? Why does it rock?

I recently gave a speech on just that: Why Exogeology ROCKS!

About Me

Posted by Petra on 11th April 2010 in Petra's Blog

If you’ve been reading this blog, you’ll already know me a bit. But I want to give you a better idea of what I’m like. For starters, I’m Petra Stone, an exogeologist. I love geology and astronomy, but I also love writing and traveling. The following are some questions that I’m often asked by people:

What are you currently working on?

  • I’m currently in Iceland working and studying glacial formations. This is research for the Mars mission I’m working on which is going to Mars’ north pole.

What is your favorite planet?

  • My favorite planet is Mars, because I think the geology is fascinating.

What is your favorite color?

  • Purple, of course! That’s why the planet on this website is purple! :)

What is the best project you have worked on?

  • My favorite projects to work on have included: identifying Martian rocks, using relative dating on alien formations, and traveling to far-off locations around Earth. I’ve never been off of Earth, but I’m sure it would an amazing experience. I’ve worked with several astronauts here at NASA who have been off-world and they’ve told me some fantastic stories.

What things do you like to do (what are your hobbies)?

  • Other than my job, some of my hobbies are reading, jewelry making (I bead memory wire bracelets usually), rock collecting (I have a huge collection with geodes, and jasper, and malachite, oh my!), stargazing and learning the myths behind the constellations, and of course, writing this blog! I like finding unique arts and crafts projects too, that can be really fun. I also love hiking. I love getting a great view of the area, and it gives me a chance to look at the rocks. :)
  • Another interest of mine is photography. I can never get my regular camera to take great objects like the moon, but it’s fun to get photographs of other things. I’ve taken photos of places I’ve been, things I’ve seen, and whatever I want to keep a record of or I just think looks cool. It can come in handy to be a fairly good photographer when you’re classifying rock samples (I use several special cameras for my job), but what really ROCKS is when I have the opportunity to take photographs through a telescope. Telescopes at observatories have great cameras for visible and non-visible light! I could never get photographs like those with my own camera. To see some samples of these, be sure to check out the NASA image gallery!

What is your favorite movie and/or television show?

  • I like science fiction movies and TV shows best, but I also like mystery shows. I like non-fiction TV shows too, but I often find long documentaries too long–I prefer shows to have a fictional storyline if they’re going to be really long.  The exception to this is The Elegant Universe. If you’ve ever been interested in physics, that show will get you even more interested! Seeing that for the first time really piqued my interest in string theory and m-theory.
  • My favorite TV shows are The Universe, Doctor Who, and, of course, Star Trek (all series, but Voyager is my favorite).

What are your favorite books?

  • Books I like are usually fantasy, not science fiction. I really enjoyed the Harry Potter series, the Percy Jackson series, the Magyk series,  and similar types of novels. I also really enjoy reading non-fiction science, especially if it has to do with time travel! I read magazines, technical periodicals, as well as the latest papers that my colleagues publish.

Do you enjoy writing?

  • I absolutely love writing! I spend most of my time writing papers about geology and exogeology (since those are the topics I know best and they are what I spend most of my time researching), but every once in a while I’ll take an interest in other topics and feel like I just have to share my findings with the world!
  • I occasionally even write haiku! Here are two examples:

Twinkling balls of light
So many lightyears away
Estrellas lindas

Rocky Mars landscape
Red mesa towers above
Like Arizona

As you can see, there’s a lot more going in my life than just my job. However, exogeology just happens to be what I like most, and a lot of the things I like are somehow related (ultimately everything seems to be related if you think about it enough). That’s just what I like!  It’s why I became an exogeologist.

My Travels

Posted by Petra on 9th April 2010 in Petra's Blog

I love to travel! I’ve been to many different countries, and nearly every U.S. state. I love going to different places and seeing the world! Some of my favorite vacations were combined with fieldwork, often unintentionally. An example of this is when I went to White Sands, New Mexico. I went there to study the dunes, and I went sledding on the sand. Alamogordo, the closest town to where White Sands is located, is a town devoted to astronomy! This is where the New Mexico Museum of Space History is located (and I highly recommend it for all ages). I also went to the solar observatory nearby in Sunspot, NM. You can’t tell from their websites just how different the observatories I’ve been to are, but they really are distinct!

Here are photographs I took of the gypsum dunes at White Sands:

Another one of my favorite trips was to the Arkansas Crater of Diamonds. It’s pretty much what it sounds like: a crater with diamonds in Arkansas. The Crater of Diamonds is the only place in the world open to the public to find diamonds. It’s not an impact crater, it’s a diatreme. That’s  volcanic crater formed by an explosion from a buildup of gas. The explosion helped to bring diamonds to the surface. I identified the rocks in the crater as lamproite, and I found some beautiful butterscotch colored jasper. I also found some quartz fragments, and volcanic tuff. I expect the moon looks a bit similar to the crater, with the gray volcanic rocks and tuff. I didn’t find any diamonds, unfortunately. The area around the crater was a very pretty and humid forest environment though, so only the crater itself is at all like something found somewhere other than Earth.

Here are a couple of photographs from when I went rock collecting there:

I went to Sunset Crater Volcano National Monument just recently. I needed to see a volcano in order to compare and contrast with Io and Martian volcanoes like Olympus Mons. Most of my work is with Mars, but I’ve been doing research for some probes like Cassini and New Horizons, too. Some of the things I found showed me that Sunset Crater is not like Olympus Mons, since Sunset Crater is a cinder cone and Olympus Mons is a shield volcano. I climbed to the top of Lenox Crater, a cinder cone right next to Sunset Crater (which you’re not allowed to climb). It was a bit tricky, especially since rocks kept getting in my shoes. It seemed a bit strange to me that there are volcanoes in Arizona, but I figured out the answer. It’s a hot spot! There are no tectonic boundaries in AZ, but mantle plumes can happen anywhere. That’s something I study with other planets, too: I find something which seems strange and I figure out what caused it. It’s like a mystery! Exogeology ROCKS!

Here are a couple of photographs I took at Sunset Crater:

I just plain like traveling, and pretty much anywhere I go I can find something that ROCKS! I take little trips around the state, like to Sunset Crater, all the time. I enjoy visiting (and using) observatories, seeing geologic formations, and going to places that are completely non-exogeology related. Be sure to look at the Telescopes and Observatories page written by Zoë to see some of the telescopes I’ve used. I want to see all the most varied and interesting places I can! But I always go back to Arizona. I love it here. Besides, what better place could there be for doing what I love? Geology and astronomy both seem to lead me all over the globe, but the best place is back home in Arizona. It works out well for me!

Geography and Astrology

Posted by Petra on 8th April 2010 in Petra's Blog

Whenever I try to tell anyone what my job title is, nobody understands! I got so frustrated when I went to a geology conference and everybody kept asking me what my sign was! That’s not what I do! I’m pretty sure I’m a Virgo, but I have no idea what that means! The same thing happens when I meet astronomers. They keep assuming that I know stuff like the capital of Nebraska. I am not an astrologer and not a geographer, I’m an astronomer who is also a geologist.

Sometimes people just slip up even when they do know the difference. I had a pretty funny conversation with my grandparents when I tried to explain my job. Here’s pretty much how it went:

Grandpa: “I heard you’re an astronaut now, Petra. That sounds exciting.”

Me: “No, Grandpa. I’m not an astronaut at all, I’m an exogeologist.”

Grandma: “You’re an ex-geologist? I thought you just started this job, whatever it is. What are you doing now?”

Me: “Ex-o. Ex-o-geology is the geology of other planets.”

Grandpa: “Oh, geography!”

Grandma: “Have you made many maps dear?”

Me: “No, not geography. And mapmaking is called cartography.”

Grandpa: “Cartography? I’ve always wanted to draw cartoons. Can you draw Pluto?”

Me: “Grandpa, I’m not a cartoon artist. How’d we even get on that subject? I study things like volcanoes and craters. Geology. And I haven’t tried to draw Pluto. But there’s this spacecraft that’s headed to…oh, that Pluto.”

Grandma: “Oh, geometry, with the shapes!”

Me: “That’s mathematics, Grandma. I’m an exogeologist. That’s a combination of geology and astronomy. I look at space rocks.

Grandma: “Like the astronauts got from the moon?”

Me: “Yes! Exactly!”

Grandpa: “That sounds fun.”

Me: “Yes, it ROCKS!”

Grandma: “So when will you be going to the moon?”

I hope this helps you to tell the differences between exogeology and completely different jobs. My grandparents finally understood after that long conversation, and I can usually get people to at least say it right. People who just haven’t heard of exogeology, or even geology or astronomy, are just part of the job. I can’t blame them really, although it is annoying. For now, I’m Petra Stone signing off. Exogeology ROCKS!

A Day in the Life of an Exogeologist

Posted by Petra on 3rd April 2010 in Petra's Blog

Want to know just what an exogeologist does all day? Well, maybe I can show you just how cool this job is!

When I start working for the day, the first thing I do is see if I’ve received any new data. This could be from other exogeologists or from different spacecraft. I sometimes even get rock samples to analyze. If I do, I’ll take them to the lab. There I’ll test the sample to find out its composition.

There are lots of tests I can do. I can test minerals for streak, hardness, cleavage or fracture, and of course note the color and shape of the crystals. For example, let’s say I was given a mineral sample to identify. It has cube-shaped crystals, and is gold in color.  I rub it on a streak plate, and the streak is greenish black. I’ll scratch it with various tools and deduce that its Mohs hardness is 6. When I break it with a hammer, the place where it breaks is conchoidal (a distinctive curved shape). All these things put together tell me that my mineral is pyrite. If I were given a rock sample, there are a lot of various tests I could do to classify a rock, like cutting a thin slice and looking at it under a microscope.

  • Here’s a quick tip about classifying rocks: If it has bubbles, it’s got to be igneous. Those bubbles are called vesicles, and they’re made when gas bubbles are trapped inside a rock as it cools.

Some days I’ll go to an observatory to do research on a planet. I need to reserve the telescope ahead of time usually. When I used a telescope at the Kitt Peak observatory, I had to reserve the telescope years in advance! But it was worth it. I got some great photographs of Jupiter and a comet during my time at the telescope. I’ve used lots of different observatories, and it’s always been productive. Well, except for that one time when it rained… I had to cancel. I must have been really unlucky that time. But that’s the trouble with astronomy; sometimes you just have to wait for another clear night. At least every other time went well.

Other days I’ll get information from a spacecraft or lander! That’s my favorite part! Once, I got to help with the LCROSS mission and interpret data from the spectrometer. The goal was to find water, and we did! That ROCKS! Since Mars is my specialty, I’ve been receiving data from the Mars Odyssey orbiter, which maps the amount of chemical elements and their distribution. I loved working on that. Maybe I’ll get to interpret data from the upcoming Mars Science Laboratory (MSL). Part of the MSL’s mission will be to study the geology of Mars.

Exogeology ROCKS!
