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 his journey to become a scientist.

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 meteorites and her journey to become a scientist.

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 teenager, he spoke a different native language and didn’t have the preparation other kids had for math and physics. Learn about Aaron’s journey in this episode of Gravity Assist.

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.
