Special Delivery from Outer Space

On September 24, 2023, a capsule from space parachuted down into the Utah desert. Tucked inside it were 4.5-billion-year-old bits of rock and dust from a faraway asteroid named Bennu collected by the OSIRIS-REx spacecraft. These pristine space rocks, which contain carbon and other building blocks of life, could rewrite scientists’ understanding of our solar system. In this episode, sit in mission control and ride aboard helicopters with asteroid mission leaders like Dante Lauretta and Mike Moreau for a behind-the-scenes look at the OSIRIS-REx sample return mission’s epic conclusion.


Tiny but Mighty

What do air pollution, thunder clouds and climate change have in common? Aerosols! These tiny particles, generated by everything from desert dust storms to car exhaust, play a huge role in our atmosphere, affecting our health when we breathe them in and even changing the weather. Globally, they play an even bigger role, changing how much sunlight gets through to Earth’s surface and heating or cooling our entire planet. Through new satellite missions, NASA atmospheric scientists like Kirk Knobelspiesse and public health experts like Susan Anenberg are working together to untangle aerosol mysteries.


How You (Yes, You!) Can Do Science With NASA

Anyone can participate in the process of NASA science and engineering through what we call citizen science, regardless of your citizenship. You might have heard it called “participatory science” or “community science.” It all means that thousands of people around the world are helping the professionals make discoveries about our planet, our solar system, and our universe at large, through these projects. Meet three volunteers whose perspectives have changed by participating in citizen science.


Hum of the Sun

What does space sound like? It’s a question that has fascinated composers and scientists alike throughout history. Through a process called data sonification, heliophysicists are using NASA satellites like audio recorders to listen to the electromagnetic symphony our Sun plays, and making new discoveries along the way.


Welcome to the Dark Side

Normal matter—the kind that makes up our home planet and everything we can see—adds up to just five percent of the known universe. The other 95 percent is dark matter and dark energy, a tag team that ranks among the biggest mysteries in all of science. NASA astrophysicists Jason Rhodes and Ami Choi explain how we study this dark side and why it’s making scientists reconsider what we think we know about the universe.


Introducing Season Six

In season six, meet researchers who are using sounds from the Sun to unlock new details about our star, explore the “dark side” of the universe with scientists who study dark matter and dark energy, and get a behind-the-scenes look at the first NASA mission to deliver an asteroid sample to Earth. A new episode drops every Tuesday.


To the Stars with Jessica Watkins

In this special season five finale episode, join NASA astronaut Jessica Watkins, self-proclaimed “rock nerd” on a journey to the stars.


Suiting up for Space

Spacesuits are more than just garments – in the airless vacuum of space or on the freezing surface of the moon, they keep astronauts alive. Explore how NASA engineers like Amy Ross and Paromita Mitra have contributed to the development of the next generation of spacesuits.


Field Notes: Nhulunbuy, Australia

Tropical rainforests, snowy mountain peaks, even the Australian outback – NASA experts travel to a wide range of environments right here on Earth to better understand our universe. Miles Hatfield, NASA heliophysics science writer, recaps a recent reporting trip to cover a sounding rocket launch in Australia’s remote Northern Territories.


How to Build A Spacecraft

Spacecraft go through a lot - exploring dangerous worlds across the cold expanse of space. Not to mention the chaos of a launch! So how do we build a mission that can take on dangerous environments and the harrowing trip to reach them? Explore the world of mission-building with scientists from Venus’ DAVINCI mission.


Stargazers Welcome

The night sky isn’t just for experts, it belongs to all of us! And we here at NASA love to encourage people to go out and take a look. Amateur astronomer Kevin Hartnett, Hubble Social Media Lead Elizabeth Tammi, and the Astronomical Society of Greenbelt take us on a tour of the stars and share how you can join from your own backyard.


Wildfires from Space

Wherever you live on Earth, wildfires touch your life. Explore how NASA scientist Doug Morton and Canadian firefighter-turned-researcher Josh Johnston use satellites to track the changing landscape of wildfires from space.


The Invisible World of Gravitational Waves

Information about the universe is all around us. But there’s more than meets the eye! Gravitational waves are the invisible ripples in spacetime caused by supermassive interstellar activity. Join astrophysicists Ira Thorpe and Judy Racusin on an exploration of how NASA studies these unseen bends in time and space.


Defending the Planet from Asteroids

Our solar system contains millions of asteroids, orbiting our sun and rocketing through the night sky! Join scientists Kelly Fast, Tom Statler, and Davide Farnocchia as we discover what we can learn from these building blocks of the universe, and how NASA would respond if one were ever headed our way.


Introducing Season Five

In season five, join us as we fight wildfires, defend the Earth from asteroids, and explore the invisible world of gravitational waves! New episodes every Tuesday.


Bonus: Happy Holidays from NASA!

Before we return with season five in 2023, celebrate the holidays with us! Join Goddard news chief Rob Garner, NASA social media lead Stephanie L. Smith, and astronaut Shannon Walker on this special, holiday-themed bonus episode.


Webb’s First Images

On July 12, 2022, a fundamentally new era of exploring our universe begins. This special season finale episode features an overview of the James Webb Space Telescope’s first detailed cosmic images. Learn what this historic moment means from astronomer Michelle Thaller.


Field Notes: Astronaut Shannon Walker

From dusty deserts to icy mountain tops, NASA experts visit incredible places along their career path. But what about our explorers who take their work off the Earth? Join astronaut Shannon Walker on a look back at her excursions into space.


Up & Away with Sounding Rockets

Explore sounding rockets, and the experiments they take to the skies, with space physicist Alexa Halford and sounding rocket program assistant chief Cathy Hesh.


The Search For Life: Are We Alone?

Are we alone in the universe? It's a question studied in science fiction, but also by teams here at NASA. Join us as we search for signs of life outside of Earth with scientists Aki Roberge, Ravi Kopparapu, and Shawn Domagal-Goldman.
