The DART mission begins its journey that will end when it smashes into an asteroid, demonstrating how we might save Earth from a devastating impact.
A first-ever encore of our wonderful conversation with the first American woman in space.
Principal investigator Hal Levison and colleagues prepare us for the launch of NASA’s Lucy spacecraft in an exclusive interview.
Mission system manager Al Cangahuala says the robotic explorer of Jupiter’s ocean moon is making steady progress toward a 2024 launch.
The Juno mission will continue its exploration of Jupiter till 2025, thanks to a four-year extension granted by NASA. Principal investigator Scott Bolton brings us up to date.
The author of The Martian introduces us to his terrific new novel and shares his thoughts about the current state of space exploration.
Composer Amanda Lee Falkenberg is joined by Cassini project scientist Linda Spilker and retired astronaut Nicole Stott as she shares excerpts from The Moons Symphony.
New research reveals why Earth is on its own in this solar system’s habitable zone where liquid surface water flows, but the same isn’t true across the galaxy.
JPL scientist Kevin Hand is endlessly fascinated by the possibility of life in the hidden oceans of the outer solar system’s moons, and now he has written a great book about the quest to discover it.
Our look ahead at the near-future of solar system exploration continues with Mars, the giant outer worlds, and the smaller bodies that can be found throughout the neighborhood.
Juno mission principal investigator Scott Bolton provides an enticing taste of the Jupiter orbiter’s mind-bending discoveries.
Astrobotic is one of several companies that are building small, robotic landers to take commercial payloads to the surface of the Moon. With a new contract from NASA to support his company’s work, CEO John Thornton looks forward to touching down in 2021. Senior editor Emily Lakdawalla can’t wait for the Europa Clipper to reach Europa, one of Jupiter’s ocean moons. Who doesn’t want more cow bell? Chief scientist Bruce Betts gets his share as he helps us explore the current night sky in What’s Up.
Astrobiology is the discipline that explores the origin of life in the universe, and whether life exists anywhere other than Earth. It’s an increasingly exciting field according to University of Washington Research Associate Michael Wong. Mike reviews the current thinking and provides some of the chemical basis for life as we know it, and possibly as we don’t know it.
magine soaring over what may be the solar system’s most Earth-like world, if you ignore the chill. If funded, the nuclear electric-powered Dragonfly will do exactly this. Principal Investigator Elizabeth “Zibi” Turtle shares her enthusiasm.
