What if we could get rid of lengthy waitlists for organ transplants? Well, imagine 3-D printing a kidney from your own stem cells. That would reduce the chances your body rejects it. That’s the sort of groundbreaking medical research astronauts are conducting aboard the International Space Station. Other research includes understanding the stress spaceflight places on not just the body, but also the mind. There’s a plethora of huma...

We’re kicking off 2025 with NASA’s deputy administrator Pam Melroy, who wraps up her tenure at NASA this month. As a former astronaut with three space shuttle flights under her belt – including one flight as commander – Pam has made lasting contributions to human spaceflight. She’s also a veteran of the U.S. Air Force as a retired colonel. In her most recent role, Pam helped shape the NASA’s focus on long-term strategies, including...

Before leaving the ground, astronauts prepare for spaceflight by immersing themselves in life-like training simulators. This is done with the help of NASA’s Simulation and Graphics Branch. Branch Chief Michael McFarlane leads a team of experts who use cutting edge technology to create digital environments, tools and visualizations that support nearly every aspect of human spaceflight. In this episode, we discuss how simulations hel...

Europa Clipper is NASA’s first mission dedicated to studying an icy ocean world. Launched aboard a SpaceX Falcon Heavy rocket on October 14, 2024, from Kennedy Space Center, the spacecraft is set to arrive at Jupiter in April of 2030 to conduct sweeping flybys of Europa. Europa is one of Jupiter’s four large Galilean moons. It’s roughly the size of our own moon, but what’s most is intriguing is that it may harbor the conditions for...

The Sun is the ultimate source of life in our solar system, a radiant powerhouse that bathes Earth in the energy necessary for everything from photosynthesis to weather patterns. Its warmth and light sustain us. However, the Sun’s influence isn't always benign. Its solar wind—a stream of charged particles—can disrupt our technology, causing communications blackouts and GPS glitches. In this episode, Dr. Joseph Westlake, director of...

We don’t yet know what dark matter is, yet it makes up 85% of all the matter in the universe. The Roman Space Telescope will aim to unravel the mystery. With a field of view 100 times wider than the Hubble Space Telescope’s, Roman will study in near-infrared light the atmospheres of planets orbiting other stars, making other exoplanet discoveries along the way. The mission is named after Dr. Nancy Grace Roman, NASA’s first chief of...
