NASA Asteroid Experts Create Hypothetical Impact Scenario for Exercise

NeRD

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This artist’s concept depicts an asteroid drifting through space. Many such objects frequently pass Earth. To help prepare for the discovery of one with a chance of impacting our planet, NASA leads regular exercises to figure out how the international community could respond to such a threat. NASA/JPL-Caltech The fifth Planetary Defense Interagency Tabletop Exercise focused on an asteroid impact scenario designed by NASA JPL’s Center for Near Earth Object Studies. A large asteroid impacting Earth is highly unlikely…

NASA’s NEOWISE Extends Legacy With Decade of Near-Earth Object Data

NeRD

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This artist’s concept depicts the NEOWISE spacecraft in orbit around Earth. Launched in 2009 to survey the entire sky in infrared, the spacecraft took on a more specialized role in 2014 when it was reactivated to study near-Earth asteroids and comets. NASA/JPL-Caltech As the infrared space telescope continues its long-duration survey of the universe, it is creating a unique resource for future astronomers to make new discoveries. NASA’s NEOWISE mission has released its 10th year of infrared data –…

NASA’s NEOWISE Celebrates 10 Years, Plans End of Mission

NeRD

NEOWISE is depicted in an artist’s concept in front of an image of the infrared sky that the mission captured. The string of red dots moving across the sky near the center of the image is Holda, the first asteroid the space telescope detected shortly after being reactivated in 2013. NASA/JPL-Caltech The asteroid and comet-hunting infrared space telescope has gathered an impressive haul of observations, but it’s now at the mercy of the Sun, which is accelerating its demise. NASA’s NEOWISE has had a busy decade. Since its reactivated mission…
