NASA Research Engineer Ryan McClelland discusses digital engineering technologies that are transforming classical engineering tasks and processes.

On the Gravity Assist podcast we have interviewed dozens of scientists, engineers, and others dedicated to the mission of NASA space exploration. After five years, the show is coming to a close. Here are some final thoughts and episode highlights from the podcast team.

NASA Space Radiation Element Scientist Robin Elgart discusses research aimed at reducing radiation health risks.

The James Webb Space Telescope awed the world on July 12 with its first images and data. And it’s just getting started with its exploration of the cosmos. Dr. John Mather, the observatory’s senior project scientist, has been working toward this milestone for more than 25 years. Before Webb, he worked on a spacecraft that delivered a groundbreaking baby picture of the universe and offered the best...

Boston University Assistant Professor Virginia Greiman discusses enduring lessons from the largest, most technically challenging highway project in U.S. history.

Ingenuity Mars Helicopter Chief Pilot Håvard Grip discusses the rotorcraft's history-making flights on the Red Planet.

The world will get a first glimpse of the universe as never before when the first images from the James Webb Space Telescope come out on July 12. And this is only the beginning — the telescope will deliver all kinds of insights about galaxies, planets, and more, for years to come. But someone has to translate that data into beautiful imagery, especially since Webb collects light that falls outside...

NuSTAR Principal Investigator Fiona Harrison discusses NASA's Nuclear Spectroscopic Telescope Array.

NASA Astrobiology Program Senior Scientist Mary Voytek discusses Research Coordination Networks.

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.
