Diviner Intern Profile: Erin Leonard

Erin Leonard (age 21) is a rising senior at UC Berkeley double majoring in Astrophysics and Planetary Science.


What is your research project this summer at JPL?

I aim to research how the porosity of a lunar soil sample affects its thermal emission, which is expressed by the surface temperature. In order to do this I am conducting a series of heating and cooling tests on lunar soil samples of varying density in SABEL (Simulated Airless Body Emission Laboratory) under atmospheric conditions, vacuum, and vacuum with a LN2 cooled thermal shield. If the density of the soil sample affects its thermal emission it may also affect its spectra which connects to the research of my mentor, Benjamin Greenhagen, and others.

Why did you choose to study lunar science?

I chose to study lunar science this summer because early last spring I did a research report on lunar volatiles and this sparked my interest and caused me to look for other current lunar research. I love how there are so many things that we can learn from the moon and then possibly apply the same knowledge to other areas in planetary science.

What are your career goals?

My career goals are broad, but I know I want to get my PhD and eventually do research.

What have you learned so far as a Diviner intern?

As a Diviner intern I have learned about the importance of being able to adapt your work or your research goals in the face of complications that are out of your control. I hope to continue to learn more about the groundtruth process and remote sensing on the moon.

What has been your favorite moment or the best part of working with the Diviner team?

The best part of working so far has been getting to work in the lab with SABEL and getting to know the team members and how they got to where they are today.

Diviner Intern Profile: Cliff Watkins

Clifford Evan Watkins (age 29) is a physics major and rising senior at St. Olaf College in Northfield, Minnesota.  He is originally from Eastern Pennsylvania.


What is your research project this summer at JPL?

I am working with Paul Hayne to further develop a model of the equatorial cold spots found by the Diviner probe. During the summer the goal is twofold: 1) to characterize the cold spots using Diviner to measure the density profile and 2) to build a mathematical model in an attempt to refute or confirm the possibility of ballistic creation processes. This problem is interesting for the sparsity of surface data collected juxtaposed to the sheer richness of the Diviner data. Therefore the problem is described well from the top down, but very minimally from the bottom up; a situation lending itself to leaps of creative logic that having a measure of useful ignorance allows.

Why did you choose to study lunar science?

I like the idea of the moon. It is marvelous to have such an intrinsically fascinating dataset, but that would be a bit of a stretch of the truth for the only reason that I am at JPL. I am also here in order to test the waters of Southern California, and more-so I just the like the story of this. I think, retrospectively, a certain edacity for stories has led me to most of the places I have ended up heedless of some of the rather steep prices paid. This oozes directly over the numbers into the next question as the prime mover for my career goals as well.

What are your career goals?

I would like to consider myself interesting, work on interesting problems, and live in places that I can surf, cycle, and adventure. Put precisely, I would like to be able to tell of good story of the things that I have done and the times I have spent doing them.

What have you learned so far as a Diviner intern?

I have learned a lot as a Diviner intern. It is fascinating working at JPL, being surrounded by competent people and seeing the processes of the system that continues to push science forward. Moreover, I had the assumption of a more complete lunar science due to Apollo era scientific progress, but Diviner has shown this to be patently false. And lastly, I have learned that a lot more work is put into a lot of the details than I ever thought possible.

What has been your favorite moment or the best part of working with the Diviner team?

Thus far, and this is probably the nerdiest, but most honest, thing I can say; my favorite moment has been staring at a whiteboard with Paul Hayne as we try to get the unit analysis correct while developing potential models. Putting ideas into words and hearing someone be interested enough in them to thoughtfully critique their structure from the standpoint of an expert is a game-changing experience.

Diviner Intern Profile: Jason Platt

Jason Platt (age 18) is a Physics major and rising sophomore at Stanford University.  He is originally from San Marino, California.

Jason Platt

What is your research project this summer at JPL?

At JPL I am helping my mentor construct thermal models of the Apollo 17 heat flow probe in order to more accurately determine the thermal conductivity of the lunar regolith. Discrepancies in the data returned by the probe have caused many to call into question the validity and reliability of the data returned by the experiment. If we can correctly incorporate these discrepancies into our models then a mystery will be solved and scientists can start to utilise the only proper thermal data ever recorded of the lunar soil.

Why did you choose to study lunar science?

My father used to take me out to the desert when I was little and take me stargazing.  I’ve been fascinated by space ever since and so when an opportunity opened at JPL in planetary science I jumped at the opportunity. I’ve never studied lunar science before but I hope to keep exploring and broadening my knowledge.

What are your career goals?

I hope to continue my education and see where it takes me.

What have you learned so far as a Diviner intern?

I have learned the value of patience when it comes to doing research. There have been a number of times that I’ve had to throw out many days work and start again from basic principles. More concretely, I have also learned the basics of heat flow as well as to use computer modelling programs.

What has been your favorite moment or the best part of working with the Diviner team?

My favourite moment happened when I came into work one day and found my mentor’s office completely covered in ridiculous photographs. The people in the planetary science division and Diviner team are fun, sociable and often completely ridiculous. I could not ask for a better place to spend my summer.

Team Welcomes 2013 Summer Interns

Diviner Team Members Paul Hayne, Ben Greenhagen, and Matthew Siegler are hosting the first class of Diviner interns this summer at the Jet Propulsion Laboratory in Pasadena, CA.  Three interns from top colleges throughout the country will spend ten weeks on Diviner-related projects before returning to their home institutions to finish their undergraduate degrees. Learn more by reading Q&As with Diviner interns Jason, Erin, and Cliff.

Below, Paul, Ben, and Matt answer a few questions about the Diviner internship program.

What do interns learn over the course of their stay?

Paul: Students learn about the Moon and more importantly, how to do science! Most summer students work on a specific problem related to their mentor’s major field of research. They develop a hypothesis, acquire and analyze data, test the hypothesis and interpret the results in order to improve our understanding of the Moon. Summer students also have lots of interaction with their mentors and other interns, and are able to attend weekly seminars on a range of planetary science topics.

How are interns selected and what should students do if they are interested in becoming a Diviner intern?

Paul: Internship programs are run through both Caltech and JPL, and interested students can learn more here.  Some of the programs require a research proposal, which the applicant writes with the help of the prospective mentor. Here is some advice from the SURF program (which includes two of our Diviner interns).

In general, we are looking for students with a strong academic background (or demonstrated potential) in geology, physics, or astronomy (or related math/science). They also have to express interest in studying the Moon! Because we JPLers tend to have busy schedules, we also look for people who are likely to be self-motivated.

How do you feel about hosting interns at JPL?

Matt: I definitely went into science because of my summer internships. They are what made me believe I could excel in grad school, because they are a lot more like grad school than they are like undergrad. They make you see that science is more than class work and takes different skills than you need for written tests. I doubt I would have thought science was going to be a very interesting career if I just saw what I had seen in class. I hope to pass that on to the students.

Ben: I’m always happy to help inspire the next generation.  A similar internship opportunity at the Lunar and Planetary Institute (LPI) is what got me into planetary science.

Diviner scientists share lunar research at UCLA outreach event

During UCLA’s Explore Your Universe outreach event, science research groups and departments from across campus share their research with the public through hands-on demonstrations and experiments aimed at students from “K through gray”.

The Diviner exhibit included animations of the Lunar Reconnaissance Orbiter launch and journey to the Moon, a lunar tour, and the LCROSS impact.  An infrared camera allowed members of the public to learn why their cars heat up when left out in the sun and how infrared cameras can see things our eyes can’t.  For more information about the event and to see more pictures and video, visit the UCLA Institute for Planets and Exoplanets.


Elliot Sefton-Nash explains the infrared camera to interested onlookers.

Michael Aye discusses his research at the Diviner outreach exhibit during UCLA's Explore Your Universe event.

Diviner scientists locate iron oxide deposits on the Moon

In a paper recently published in the Journal of Geophysical Research, four Diviner team members estimate the abundance of iron oxide (FeO) at the sites of several volcanic deposits on the Moon’s surface.

Determining the distribution of iron oxide on the lunar surface may hold important clues about the Moon’s geologic history and may also provide an important inventory of lunar resources for future human exploration endeavors.

Billions of years ago, geologic activity on the Moon launched magma from the surface, allowing small bead-like pieces of volcanic glass to solidify in midair. Eons later, Apollo astronauts collected soil samples containing these translucent projectiles and returned them to Earth for analysis. Colored primarily orange, black, and green, the bits of volcanic ejecta are rounded and each about the width of a human hair.

By measuring the thermal properties of lunar samples in an Earthbound laboratory, first-author Carlton Allen developed conclusions about data taken from lunar orbit by the Diviner experiment, onboard the Lunar Reconnaissance Orbiter. To calibrate the spacecraft’s measurements, Allen compared Diviner spectral signatures to the compositions of soils from Apollo landing sites.

Of the three volcanic deposits Allen analyzed, two were rich in iron oxides and volcanic glasses (regions named Aristarchus and Sulpicius Gallus), while the third was not (a region called Rima Fresnel).

Additional authors of this study include researchers Benjamin Greenhagen, Kerri Donaldson Hanna, and David Paige.

To learn more about this study, read the original paper.
