How to Grow Plants in Space

As humanity sets its sights on longer-term life in space, we’re going to need ways to sustain ourselves. That’s where plants come into play! Take a tour of Kennedy Space Center’s lush Plant Processing Area with Ray Wheeler, Ralph Fritsche, and Gioia Massa - the scientists studying how to grow food in space!

Going Supersonic!

When a plane flies faster than the speed of sound, you get a sonic boom! But what if we could change those physics? Join NASA test pilot Nils Larson and aerospace engineer Lori Ozoroski to hear how we’re flying faster than the speed of sound, and making that supersonic flight quieter, too.

Earth’s Weather Watchers

Planets throughout the universe are full of fascinating weather, including Earth! Hear how NASA and NOAA work together to predict, monitor, and respond to Earth’s ever-changing weather. Explore Earth’s weather with Dalia Kirschbaum, Marangelly Fuentes, and Dan Lindsey.

Mysteries of the Moon

The Moon is our constant cosmic companion and the only planetary body outside of Earth where humans have set foot. As we prepare to head back to the Moon with the Artemis program, let's take a look at what we know about this wonderful and mysterious natural satellite.

Introducing Season Four

In season four, explore the lifesaving systems of space suits, break through the sound barrier, and search for life among the stars. First-time space explorers welcome.

Bonus: Still Curious?

At NASA, we are driven by curiosity, and we know you are too! Join us as we hear from our previous episode experts about what they’re interested in and answer some questions from listeners like you. What are you still curious about?

Webb Space Telescope: Go for Launch with ESA Expert

After years of preparation and anticipation, it’s time to send the world’s most powerful telescope to space. Ariane 5 rocket expert Rudi Albat (ESA) takes you through launch day and describes why the launcher that will carry Webb to its final destination is one of a kind.

Webb Space Telescope: The Global Village

A scientist from Italy who studies baby stars. A Californian spacecraft refrigeration pioneer. A Dominican-American engineer who saw space as her refuge from a tough life at home. Meet three people who represent a small slice of the thousands who have worked on Webb worldwide.

Webb Space Telescope: Building the Next Discovery Machine

Webb is preparing for a million-mile journey to its lookout point over the universe. Engineers have been hard at work designing, installing, and testing the world’s next discovery machine that will change astronomy for years to come. Join Kenneth Harris, Joe Sprofera, and Rene Doyon as they explain what it took to engineer Webb

Webb Space Telescope: Into the Unknown

The James Webb Space Telescope is going to open a new window into the universe. It will show us stars, galaxies, planets, and other objects as we’ve never seen them before. In the first of four episodes of our mini-series, we focus on the great science that Webb will do.

Curious Universe: Introducing the Webb Space Telescope Mini-Series

NASA is preparing to launch the largest and most powerful space telescope ever constructed. Join us for a special James Webb Space Telescope mini-series as we explore the science, engineering, people, and launch of this historic mission.

A Day in Space

Have you ever dreamed of spending a day in space? Join astronauts Shane Kimbrough, Megan McArthur, and Thomas Pesquet throughout their day living and working on the International Space Station.

Journey to Venus

Let’s go to Venus! This year, two NASA missions were chosen to explore Earth’s “twin” planet, Venus. But with extreme temperatures and toxic clouds, these missions have to prepare for a difficult journey. Join Venus experts Jim Garvin, Sue Smrekar, and Giada Arney on a tour of Earth’s “twisted sister”.

Rocket Assembly Required

Twenty-four American astronauts went to the moon between 1968 and 1972. In the next few years, we are going back. To get there, we’ll need a dedicated team, and a powerful new rocket. NASA’s Sharon Cobb and Abdiel Santos Galindo take us through the many, many steps involved in preparing for launch.

Plasma, Plasma, Everywhere!

The night sky is full of planets, satellites, and cosmic objects we can see with our eyes and telescopes. In between all that material there’s a huge amount of invisible matter and the vast majority of it is called plasma. Follow along with scientists Doug Rowland and Don Gurnett, as we journey through this mysterious and electrifying substance.

Curious Universe: Building Highways in the Sky

When you think of NASA, you probably think about outer space. But the first “A” in NASA - aeronautics - means we’re busy crafting a lot closer to home. Aerospace engineers Shivanjli Sharma, David Zahn, and Mike Guminsky are hard at work inventing and testing new ways to fly.

Curious Universe: Earth’s Expanding Oceans

With Earth’s recent record-breaking temperatures, the pace of sea level rise has accelerated. NASA scientists take us on a trip into their research right here on our home planet. Join us as we fly over Antarctic ice sheets and consult with orbiting satellites on this exploration of our changing Earth.

Curious Universe: Interpreting Our Universe

You’ve probably seen beautiful images of space taken from telescopes around the world and out in orbit.  But how does a bunch of intergalactic information become a vibrant photograph?  And what else can we see, feel, and hear from that data? Scientists Kenneth Carpenter, Kimberly Arcand, and Denna Lambert help us translate the universe.

Curious Universe: Let’s Go Planet-Hunting!

What do we know about the planets outside our solar system? NASA planet hunters Jessie Christiansen and Knicole Colon take us beyond...into the exciting world of exoplanets.

Introducing Season Three of Curious Universe

Inside a Black Hole

Don't let the name fool you: a black hole is anything but empty space. Black holes are some of the most extreme, bizarre and fascinating objects in the universe. Regina Caputo and Jeremy Schnittman describe what it might be like to go hunting for one.

The Crawlers

A pair of behemoth machines called crawler-trans­porters have carried the load of taking rockets and spacecraft to the launchpad for more than 50 years at NASA’s Kennedy Space Center in Florida.

Seasons of the Sun

As Earth makes its annual trip around the Sun, we feel the impacts of its journey in the form of seasons. Our planet’s tilt in relation to the Sun determines what season we experience here on Earth. But, did you know that the Sun goes through seasons too? Delores Knipp, Dean Pesnell and Sabrina Savage explain.

From Space to Farm

Farmers rely on the accuracy of a crucial NASA and USGS mission, Landsat, to make decisions about crops. Those decisions have far-reaching implications that can impact what you see on your dinner plate!
