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.

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.
