The data science field is rapidly expanding, but is often driven by the private sector, which monetizes data.
On Wednesday, June 8, nearly 50 people from three dozen academic institutions across the country virtually attended the inaugural meeting of data science in libraries, hosted by Arizona State University, to tackle the question: What does a library perspective mean to data science?
“The ASU Library’s Data Science and Analytics team wanted to bring together our colleagues to share our activities and imagine new work in data science that could happen in libraries,” said Michael Simeone, director for data science and analytics at ASU Library. “The goal of data science in libraries isn’t to echo Google and Facebook, but to introduce more people to the practice of data science and meet the needs of our students, faculty and staff. We want to understand what the unique contributions of libraries can be when it comes to data science.”
What is data science?
More than a discipline, data science is a direction that allows exploration using models and visualizations to shift thinking from understanding to prediction. The ASU Library’s Data Science and Analytics unit was established in 2016. At the time, data science units within libraries were unique, but quickly became common at academic libraries.
By offering workshops, open labs and research consultations, data science units engage machine learning; data analytics; visual storytelling; network analysis; and text and data mining. Working within the heart of the university, libraries help people in disciplines ranging from the humanities and social sciences to engineering and math with research and coding.
The conference introduced several topics covering activities to challenges, and successes to collaborations, that attendees discussed through Zoom. Events and workshop series like “Data and Donuts” to “Data at your Desk” introduced students and faculty to various data science topics, like R and Python programmingR is a statistical language used for the analysis and visual representation of data. Python is a high-level, interpreted, general-purpose programming language better suitable for machine learning, deep learning and large-scale web applications.. When the pandemic started, data science units shifted their events online and found success attracting audiences virtually.
“‘I didn’t know libraries offered data science!’ is an often-heard expression, and we wanted to hear how units are telling stories about how they transform a student’s career or a faculty’s research project,” said Rittschof. “We were thrilled with the outcome and that we, the attendees, want to work together, coordinate events, share resources, and not wait until next year to get back together.”
Many data science units see success by partnering and collaborating across campus. At ASU, the library’s Data Science and Analytics unit has worked with biologists, social scientists, engineers, geographers and nonprofit organizations.
‘The library is your lab’
In addition to workshops, data science units work with classes, develop training materials and join platforms that promote discovery. One unit offered a machine learning club on Discord.
“We’re teaching people how to use tools and become competent with those tools,” Simeone said. “This meeting gave all of us inspiration for the work moving forward to continue developing new events, research opportunities and collaborations.”
Data science in libraries offer students, faculty and staff upskilling opportunities. One attendee shared the phrase “The library is your lab” as a reminder for how libraries continue to be places of discovery that reach all programs and disciplines at the university.

NASA selects ASU lunar exploration instrument to reveal new details about moon’s Gruithuisen Domes
On the surface of the moon stand two large geological domes of unique composition — each similar in size to Mount St. Helens — but how they formed on the lunar terrain remains a mystery.
On Earth, similar features typically form from highly viscous magmas, commonly composed of much more quartz and much less iron than is typical for the rocks found on the moon.
Dome-like volcanic formations like these need a significant amount of repeated reworking and reprocessing of rocks and minerals to form. On Earth, this can be aided by our oceans of water and plate tectonics, but without these key ingredients on the moon, planetary scientists have been left to wonder how these domes formed and evolved over time.
A new NASA space mission involving Arizona State University and led by Kerri Donaldson Hanna of the University of Central Florida aims, for the first time, to answer key questions about how these formations came to be.
“This will be the first time that we have investigated these types of features up close on the surface of another planetary body,” said Craig Hardgrove, co-investigator of the Lunar Vulkan Imaging and Spectroscopy Explorer (Lunar-VISE) mission. Hardgrove, an assistant professor in the School of Earth and Space Exploration and director of projects for ASU’s NewSpace Initiative, will develop an instrument that will be part of Lunar-VISE.
“We are thrilled that our complimentary suite of instruments from ASU and Ball Aerospace were selected to rove about and study the Gruithuisen Domes to better understand how they formed,” added Donaldson Hanna, principal investigator of Lunar-VISE.
ASU News spoke to Hardgrove to discuss the exciting lunar research, ASU’s key role and what the findings could mean for the future of the moon.
Question: Can you tell us about the moon’s Gruithuisen Domes? And what are the goals of this space mission?
Answer: The Gruithuisen Domes are hypothesized to be rhyolitic domes that formed by a sticky magma rich in silica, similar in composition to granite, but it’s a little bit of a mystery how we get these more evolved compositions on planetary bodies like the moon that don’t have large bodies of water or plate tectonics.
For this mission, we want to sample around these dome features to understand how they formed. There are a few different hypotheses and many papers over the last 20 or 30 years characterizing these features from orbit, but we still don’t know how they formed.
If we can measure the composition of the rock around the domes, as well as some of the dome material itself, that’ll help us figure out which process was at work.
Q: How is ASU involved?
A: I’m a co-investigator and instrument scientist on the mission, and our group at ASU will be providing NASA with a neutron and gamma-ray spectrometer that will be mounted on the rover and land on the surface of one of the Gruithuisen Domes.The neutron and gamma-ray spectrometer is an instrument that will measure the elemental composition and hydration of the surface around the domes down to about a meter (3 feet) into the ground.
With it, we’ll get information about all the elements in the rocks in the ground surrounding the rover – how much thorium, how much iron, how much silicon, as well as how much hydrogen, which tells us about the telltale presence of water in the area.
Q: Will the neutron and gamma-ray spectrometer be designed and built at ASU?
A: Yes, ASU is leading the development and delivery of that instrument to the Lunar-VISE rover. The instrument will be designed and built here at ASU in one of our clean rooms in ISTB4. This is made possible, in part, because of the academic and commercial collaborations we have through ASU NewSpace, and the instrument will be based on our previous instrument, the Miniature Neutron Spectrometer (Mini-NS), which was developed for the LunaH-Map mission.
We will be qualifying the instrument here, doing thermal vacuum testing and making sure it’s ready for operations on the surface of the moon and that it can survive all the launch loads it will experience on its trip to the moon. We will deliver it to Ball Aerospace in Colorado, who’s doing instrument integration into the rover.
Once on the moon, all the scientific data that the neutron and gamma-ray detector collects will come here to ASU, which we will process and analyze to provide measurements of the amounts of thorium, iron and other elements in the rocks, as well as potentially how much water is there.
The operation of the rover is planned to be 10 days long and launch is currently planned for 2026.
Q: What do you think you will find?
A: Ideally, we would like to confirm or deny some of the excellent theories about the formation of these features that have been made from previous data that were collected from orbiting spacecraft. There have been many ideas about how these domes formed, and some of them say thorium levels should be high. Some of them say the thorium should be low. We are going to go to spots around the domes and measure it.
If we can measure thorium content, as well as the iron and other elemental contents of the rocks, that will be one piece of the puzzle to help us nail down a particular formation mechanism for these domes.
Q: Why is it important to know how and why these lunar domes formed?
A: This is a scientific mission of exploration. We don’t understand fully how these dome features formed and, for now, we only have theories. Proving one or more of our theories right or wrong will help us understand the history and evolution of the moon, our nearest planetary neighbor in space. Proving theories right or wrong is fundamental to our jobs as scientists and explorers, and it helps us understand the world and our place in it.
On Earth, geologists as far back as the early 1900s had a theory that plate tectonics was a dynamic happening on this planet. At the time, many people said it was crazy. Then, through careful study, they figured out that it was something that happened and had been happening over the planet’s evolution. Now, we take it for granted that the continents on our planet weren’t always like they are today; they have moved around on the surface of the Earth.
