Two of NASA’s great observatories had a front row seat to a first of its kind NASA test for defending Earth against potential asteroid or comet hazards.

NASA’s James Webb Space Telescope and Hubble Space Telescope teamed up to collect data before and after NASA’s Double Asteroid Redirection Test (DART) intentionally slammed into Dimorphos, the asteroid moonlet in the double-asteroid system of Didymos, at nearly 15,000 miles per hour.

Not only will ground-based telescope observations help determine how successful the test was in altering the asteroid’s orbit, but the combined capabilities of Webb and Hubble together —on the same target, at the same time— will allow scientists to analyze a wide array of data relating to the makeup and history of our solar system.
