36-Spaceship Earth: Overseeing space…& Earth
When Christa Peters-Lidard cold-called the head of NASA’s hydrology lab as an undergrad, she wasn’t thinking she’d eventually land that very position. Now as the Acting Director for Sciences and Exploration at NASA’s Goddard Space Flight Center, Christa oversees several critical programs – either orbiting, like the James Webb Telescope, or currently in development – by ensuring scientists have the resources they need for a successful mission.

33-Spaceship Earth: Discovering water on Earth from space
Being a Hydrologist was never on Matthew Rodell’s radar, let alone working for NASA. But he always trusted the path ahead.

32-Spaceship Earth: A love of space through a son’s telescope
Sparked into Earth Space Science through her son’s curiosity with space, we talk to Dorian on how her journey as an educator and life-long learner led to working on NASA’s Global Precipitation Measurement Mission as a Senior Outreach Specialist, and how citizen scientists from around the world are providing important work for researchers through the GLOBE Observer Project.

31-Spaceship Earth: Using satellites to feed the world
Chris Justice is a geographer and professor at the University of Maryland whose research on land use changes and global agriculture has taken him around the world.

30.5-Spaceship Earth
What do folks who fight food insecurity with satellites, do outreach about Pluto, and map out the Earth’s gravitational fields have in common? How about a common thread between those who study light pollution, create science visualizations, and direct exploration?

Distillations: Mapping the seafloor with computer games
Many might think that we know most or all there is to know about our world. On the surface, that might be somewhat true. But below the surfaced, we’ve mapped less of the oceans than of places outside our world like Mars and our moon.

Distillations: Quilting science & changing climates
When you think of a combo of science & art, what comes to mind? Drawings? Dance? Music? How about quilting? Laura Guertin, Professor of Earth Science at Penn State Brandywine, was looking for creative and innovative to do just that when she came across the idea of showing the effects of climate change (among other things) via quilts!

Distillations: Bringing equity to community science in Chicago (& beyond)
While climate change is a global issue, it affects people on a local, and sometimes personal level. And it disproportionately affects those from traditionally marginalized backgrounds. Luckily, there are people out there like Amaris Alanis Riberior, Center Director of the North Park Village Nature Center at the Chicago Park District, who are working to create an inclusive, intercultural, and interdisciplinary understanding of climate change from a diverse community-based perspective with our colleagues in the Thriving Earth Exchange.

Distillations: Clean water in the Navajo Nation
Fresh water is something that many of us take for granted. But for Carmen George and Brianna John, it’s not a trivial thing. They’re working to bring clean water to the Navajo reservation through Community Outreach and Patient Empowerment. We chatted with them on day two of our annual meeting where the theme is Future of the Planet.

Distillations: Sharing science for the public good
It’s that time of year again. No, we’re not talking about the holiday season (though, happy holidays everyone!). We’re talking AGU’s annual meeting! To celebrate, we’re releasing an episode each day of the conference, corresponding with the theme of the day.

30-Fire: Bringing fire back to the land
Fire is a part of life for many indigenous groups, but for decades cultural burning was restricted and even criminalized. Now, fire is being brought back to the land by indigenous groups to help prevent big blazes, create resilient ecosystems, and provide resources for indigenous communities.

25-Fire: Forests under (mega)fire in the Pacific Northwest
Climate change is accelerating as human-made greenhouse gasses continue to warm our atmosphere. Megafires certainly evoke climate change doomsday feelings, but are these types of fires new to the PNW or were similar instances occurring prior to 2020?

24.5-A podcast of fire and ice
As the leaves change and temperatures cool, head inside, fire up your headphones, and get ready for hot-podcast fall as share stories about, well, fire. Join us over the next six weeks to hear stories about wildfires, volcanoes, fire in space, and on other planets, indigenous fire knowledge, and…fireflies!

23-Storied careers: Auroras, deadly radiation, and Earth’s long-term future
With a heliophysics career spanning across nearly five decades, Thomas Earle Moore has always been fascinated by the Sun’s relationship with the Earth and how that relationship affects life on our planet.

22-Storied careers: Ocean sensors and dog scenters
Tommy Dickey is an emeritus oceanographer from U.C. Santa Barbara and Naval Operations Chair in Ocean Sciences. His modeling and observational research yielded ocean monitoring technologies and tools. For retirement, Tommy trains and deploys Great Pyrenees as therapy dogs, while studying scent dogs’ capacity to detect COVID-19.

21-Storied careers: Scouring seas from the skies
This episode is about how satellite technology is being used to study a big chunk of the earth’s surface. Seventy percent of the earth comprises water but we know very little about it. Color sensors aboard some satellites can actually reveal a lot about phytoplankton or microalgae blooms that are linked to ocean temperatures. These tiny organisms contribute to half the photosynthesis on the planet.

18.5-The (not so) secret histories of scientists
Science is all about experimentation, discover, and sharing those results. But what happens behind the scenes? What stories do scientists have to tell that don’t make it in the manuscript or the classroom lecture?

18-Ice: Ancient knowledge for modern tech
To the untrained eye, Arctic ice appears unchanging, but conditions can shift quickly, and often reveal life-threatening hazards when they do. It is an unforgiving environment, but the Inuit know how to navigate it. That knowledge has been passed down through generations, and a new app is giving centuries-old Inuit knowledge a very modern form.

16-Ice: Shells of an ice-less past
Brian Huber is a climate detective at the Smithsonian who grew up collecting arrowheads in the woods of Ohio, but now collects and studies fossils from sediment cores. Brian uses fossils of tiny organisms − foraminifera − to track climate over millions of years, including the Cretaceous Hot Greenhouse climate.

15-Ice: Birds foretelling climate change
Anant Pande is an Indian polar researcher who studies snow petrels – shy pelagic (sea-faring) birds who nest on rock crevices in Antarctica. These endemic birds prefer to nest near less icy waters. Climate change has melted polar oceans and perhaps made it less energy intensive — as they have to fly shorter distances to find non-frozen oceans.
