NASA's Tiffany Nickens discusses habitats being developed for living on the lunar surface and traveling to Mars.

Astronauts on the International Space Station have been conducting experiments to grow food, including peppers and radishes. Christina Johnson, a NASA postdoc fellow at NASA's Kennedy Space Center in Florida, has been working on a variety of techniques to grow food in space. Learn what she thinks about the future of growing food beyond our planet, including on Mars.

NASA's Edward Kim and NOAA's Pam Sullivan discuss NASA's role in weather research.

Space botanists are working on strategies to grow crops on the lunar surface, as NASA makes strides toward sending astronauts to the Moon through the Artemis program. A team of scientists at the University of Florida successfully grew small plants in lunar soil brought back during three different Apollo missions. How did they do it, and what does it mean for the future of space exploration? Dr. An...

NASA Chief Scientist and Senior Climate Advisor Kate Calvin discusses the agency's role in climate research.

An ice shelf collapsed in East Antarctica in March 2022, concerning scientists who track melting glaciers, sea level rise, and other effects of climate change. Catherine Walker, a visiting scientist at NASA’s Goddard Space Flight Center, uses NASA satellite data to look at the progression of events like this one to understand how large ice structures collapse. She is also looking at Jupiter’s moon...

NASA Water Resources and Agriculture Program Manager Brad Doorn discusses how NASA tools and data help solve big problems on Earth.

On a quest to find out if we are not alone in the universe, Ravi Kopparapu at NASA Goddard studies how we could use telescopes to detect signs of life beyond our solar system. These include both signs of biology and technology, since there are certain kinds of signals and chemicals that do not occur naturally. Learn about the planets that are most exciting to Ravi and how science fiction inspired...

NASA Johnson Space Center Engineering Director Julie Kramer White discusses the skills required to be a top-notch engineer.

This recording was made by the Perseverance Mars rover on February 9, 2022 (Sol 346). The puffs and pings of the rover’s Gaseous Dust Removal Tool (gDRT) were collected using a microphone on the rover’s chassis. The gRDT has a tank of nitrogen gas and is used during sample collection to blow the dust away and reveal the fresh rock surface underneath.

NASA Space Launch System Chief Engineer John Blevins discusses the rigorous engineering of the world's most powerful rocket.

How do we know if a rock came from the Moon, Mars, or an asteroid? Planetary scientist Neyda Abreu has looked inside all kinds of meteorites to understand where they came from and what’s inside them. She also traveled to Antarctica to hunt for space rock treasure. Since she was a child in Venezuela, she has been curious about the life cycles of stars and planets. Learn about her work with meteorit...

NASA Aeronautics Research Mission Directorate Chief Engineer Steve Hirshorn discusses what it takes to be a successful chief engineer.

The James Webb Space Telescope, which launched Dec. 25, will allow us to see the farthest galaxies and better understand the origins of the Milky Way. Aaron Yung at NASA’s Goddard Space Flight Center is preparing for these historic observations by simulating what Webb will see in the early universe. But Aaron’s path to mind-bending research wasn’t easy. When he came to the United States as a teena...

NASA Chief Engineer Ralph Roe discusses engineering best practices.

In space, we have to expect the unexpected. Sunny Panjwani of NASA’s Johnson Space Center shares how he got thrown into an emergency situation on his first day as a flight controller. His team makes sure that astronauts have a safe environment on board the International Space Station. Learn how he got to NASA and how he handles high-pressure circumstances in and out of Mission Control.

NASA's John Brophy discusses the VERITAS mission to Venus.

NASA's Mike Sekerak discusses the DAVINCI mission to Venus.

NASA's Kristin Morgan discusses 2021 progress and what's ahead for the Artemis Program in 2022.

NASA is about to launch a new spacecraft to look at the universe in X-ray light. The Imaging X-Ray Polarimetry Explorer, IXPE, will look at extreme objects such as black holes, neutron stars, and supernovae, asking fundamental questions about how high-energy light gets produced. The mission’s principal investigator, Martin Weisskopf, based at NASA’s Marshall Space Flight Center, has been studying...

NASA's Les Johnson discusses solar sail propulsion and the upcoming Near-Earth Asteroid Scout and Solar Cruiser missions.

A spacecraft is about to begin its journey to crash into an asteroid on purpose. NASA’s Double Asteroid Redirection Test Mission, or DART, will deliberately impact a small asteroid called Dimorphos to deflect its orbit around a bigger object, Didymos. While this system presents no danger to Earth, an asteroid the size of Dimorphos would cause regional devastation if it hit our planet. DART will de...

James Webb Space Telescope Program Director Greg Robinson discusses NASA's largest and most powerful space science telescope ever constructed.

NASA's Marc Rayman discusses the legacy of the Dawn mission to the two most massive bodies in the main asteroid belt.

As NASA prepares to send astronauts to the Moon through the Artemis program, engineers are working on technologies that will give these explorers power – solar power, that is. In space, the harsh radiation and huge temperature changes make for a challenging environment. Lyndsey McMillon-Brown at NASA’s Glenn Research Center leads a study of solar cells made from a material called perovskite. This...
