One giant leap: For space librarians & accessible data

When it comes to data archiving, Michele Thornton has you covered. As a Geospatial Data Professional for ORNL-DAAC, Michele ensures that NASA funded research is accessible not only to researchers out in the field but to a larger user community – archival work that is vital for future researchers.

One giant leap: For meteorology & climate communication

As a leading international expert in weather and climate and Georgia Athletic Association Distinguished Professor of Geography and Atmospheric Sciences at the University of Georgia, James Marshall Shepherd knows a lot about climate, and just as importantly, how to talk about it.

One small step…for Third Pod?

We're back! And this time, we're heading to the moon! Well, not the moon, but to space! Well, that's not quite true either. But we are starting season two with a series all about people who with for and with NASA.

Your favorites: Not your science fair volcano

For many of us, the word “extinctions” conjures up images of dinosaurs, asteroids, and (maybe?) volcanos. And while that last point did likely play a role in the demise of the dinosaurs, volcanos in their own right can go extinct.

Your favorites: A Martian on Earth

Tanya Harrison never thought she was going to be an astronaut. But she was determined to go to space. And she did just that – through satellites, first to Mars, and now looking back at our own third rock from the Sun as she uses satellites to map places near and far.

Your favorites: Dinosaurs, a big rock, and…climate change?

When you hear the word “extinction,” chances are you probably think of the extinction of the dinosaurs and a big rock. But did you know that there were other factors at play that lead to that extinction including volcanos and sea-level rise?

Your favorites: The ice ships of Project Habbakuk

Dive down into the freezing depths of Patricia Lake, in Alberta’s Jasper National Park, and you will find the wreck of the Habbakuk—a sixty-foot model battleship originally constructed of wood and ice.

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.

35-Spaceship Earth: The (visual) beauty of science

As the Scientific Visualization lead for NASA’s Goddard Space Flight Center, Mark SubbaRao oversees the translation of NASA science into images and movies. For Mark, science visualization is a key communication tool that allows the public to interact and explore the various scientific discoveries happening at NASA and beyond.

34-Spaceship Earth: Powering humans in space

As the Deputy Program Manager for NASA’s Radioisotope Power Systems Program at Glenn Research Center, Concha Reid leads a team overseeing and monitoring devices that heat and give power to NASA space projects, such as the recent Orion spacecraft for Artemis 1.
