What’s next for Webb as it cools down over the next five months and looks to #UnfoldTheUniverse?



Episode 40 - We're Crashing a Spacecraft into an Asteroid...on Purpose!

DART is a spacecraft designed to impact an asteroid as a test of technology. DART’s target asteroid is NOT a threat to Earth. This asteroid system is a perfect testing ground to see if intentionally crashing a spacecraft into an asteroid is an effective way to change its course, should an Earth-threatening asteroid be discovered in the future.



Episode 39 - Launching Lucy to the Trojan Asteroids

Going where no spacecraft has gone before, NASA’s Lucy mission will embark on a 12-year journey to Jupiter’s Trojan asteroids. As time capsules to the early solar system, these ancient remnants could give scientists vital clues about how the planets formed 4.5 billion years ago.



Episode 38 - Landsat: A Legacy of Seeing Earth from Space

Earth is changing, and these changes can be seen from space. A series of satellites built by NASA and operated by the U.S. Geological Survey (USGS) have been monitoring and tracking changes across our planet for almost 50 years. Adding to this legacy circling the globe every 99 minutes and collecting images of the Earth landscapes and coastal regions, Landsat 9 will continue to answer the many questions we have about Earth’s climate change, population growth and even your very own food supply.



Episode 37 - Moon to Mars Ice and Prospecting Challenge

NASA Science Live is back and we’re LIVE from the Moon to Mars Ice & Prospecting Challenge. Ten teams from across the country have been tasked with one goal: to extract ice beneath a simulated lunar or Martian surface.
