Jason Wright, professor of astronomy and astrophysics at Penn State, has been thinking about the different technosignatures we could pick up using the telescopes we already have, and the telescopes that we could develop in the future.

NASA’s upcoming Mars Perseverance rover, scheduled to launch in July, is bringing a set of technologies to explore the Red Planet in new ways. Mitch Schulte of NASA Headquarters discusses this mission and the effort to explore whether...

The Ingenuity helicopter made history on April 19, 2021, with the first powered, controlled flight of an aircraft on another planet. How do engineers talk to a helicopter all the way out on Mars? How about other spacecraft? We’ll hear...

As the Perseverance Rover flies toward Jezero Crater on Mars, which once hosted water, astrobiologists are interested in places on Earth that are similar to the rover landing site.

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.

NASA’s Spirit and Opportunity rovers were only supposed to rove around Mars for 90 days. Listen in with Steve Squyers from Cornell University as he recounts the amazing discoveries we’ve made about the Red Planet because of these two...

We now know there are more planets than stars in the galaxy. Many of them are very different from ours. How would we know if any of them had life? Shawn Domagal-Goldman, astrobiologist at NASA’s Goddard Space Flight Center, discusses...

It's been 50 years since humans walked on the moon. Now NASA is planning to return, this time to stay. What will future lunar missions look like? Why do we go back at all?

The Moon has a large supply of water that could be useful in future human exploration, says NASA scientist Jennifer Heldmann.

NASA’s Europa Clipper mission will give us the most detailed look yet at Jupiter’s extraordinary moon Europa.

How do astronauts exercise on the International Space Station? How do they train underwater? Tara Ruttley, associate chief scientist for microgravity research at NASA Headquarters, has worked on a lot of fascinating projects to support...

In some ways, spaceflight changes you forever,” says Ken Bowersox. Since he was 7 years old, Ken knew he wanted to become an astronaut. In his astronaut career, he participated in many exciting missions, including an extended stay on the...

Astronomer and historian Steven Dick tells us there are many approaches to consider and many questions we should ask ourselves to get ready, in case extraterrestrial life is found.

Dana Bolles has worked in many exciting areas of NASA including assuring the safety of experiments and spacecraft going to space, managing environmental programs, and thinking about the possibility of life beyond Earth.

The Curiosity rover has been probing the secrets of Mars since its arrival in 2012. Its discoveries include chemical signatures that could be related to life – or, alternatively, to geological processes.

With Jim Green today is the “man about Mars,” Bruce Jakosky from the University of Colorado. Bruce is the principal investigator of NASA's MAVEN mission. Joining them is Michael Meyer the lead Mars scientist at NASA Headquarters.

When future astronauts explore the surfaces of the Moon, Mars, or beyond, they’ll have big challenges communicating with Mission Control back on Earth.

Thomas Zurbuchen, the Associate Administrator of NASA’s Science Mission Directorate, joins NASA Chief Scientist Jim Green to discuss the mysterious we still need to solve about the Sun, and more!

In this episode of Gravity Assist, Jim Green talks with New Horizons Principal Investigator Alan Stern of the Southwest Research Institute about what the July 2015 flyby of Pluto revealed about this mysterious and diverse world.

The idea for NASA’s Mars Ingenuity helicopter began at the Jet Propulsion Laboratory with a team of dedicated engineers who believed in something seemingly impossible. MiMi Aung served as the project manager on the helicopter, which has...

What does it take to drive a rover that’s more than 100 million miles away? Sophia Mitchell at NASA’s Jet Propulsion Laboratory has been driving the Mars Curiosity rover since 2018.
