Puh, das war knapp, im kosmischen Maßstab fast schon ein Streifschuss! Und der #Asteroid #2023NT1, der am 13. Juli die Erde weit innerhalb der Mondumlaufbahn passierte, war auch nicht gerade klein - etwa dreimal so groß wie der #Meteor von #Tscheljabinsk vor zehn Jahren. Entdeckt wurde er (wie dieser) deshalb nicht, weil er aus Richtung der Sonne kam... Glück gehabt 😅

Here we GO! 🚀 #NASA's next-generation asteroid-hunting space telescope has begun construction after passing a critical project milestone at the end of November. #NEOSurveyor is now a NASA mission and, when it launches, it'll seek out some of the hardest-to-find near-Earth objects in support of NASA's planetary defense strategy. It's going to be an exciting few years as I work with the project team to help amplify their critical work: https://www.jpl.nasa.gov/news/construction-begins-on-nasas-next-generation-asteroid-hunter

NASA officials have completed a rigorous technical and programmatic review, known as Key Decision Point C (KDP-C), and confirmed NASA’s Near-Earth Object Surveyor space telescope (#NEOSurveyor) establishing NASA’s commitment to the mission’s technical, cost, and schedule baseline. The decision commits NASA to a development cost baseline of $1.2 billion and a commitment to be ready for a launch no later than June 2028: https://blogs.nasa.gov/neosurveyor/2022/12/06/nasas-neo-surveyor-successfully-passes-key-milestone/
