NASA, FEMA, Other U.S. Partners Simulate Asteroid Impact Response

LAUREL, Md. (NASA PR) — This past month, NASA, FEMA, the United States Space Command, and other federal, state and local agencies convened for the fourth iteration of a Planetary Defense Interagency Tabletop Exercise to inform and assess our nation’s ability to respond effectively to a (simulated) asteroid impact threat to Earth. While there are no predicted asteroid impact threats to our planet for the foreseeable future, this exercise—sponsored by NASA and FEMA and hosted by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland—focused extensively on federal and state government coordination that would be necessary to respond to such a threat should one ever be discovered.

WASHINGTON (NASA PR) — The NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS)—a state-of-the-art asteroid detection system operated by the University of Hawaiʻi (UH) Institute for Astronomy (IfA) for the agency’s Planetary Defense Coordination Office (PDCO)—has reached a new milestone by becoming the first survey capable of searching the entire dark sky every 24 hours for near-Earth objects (NEOs) that could pose a future impact hazard to Earth. Now comprised of four telescopes, ATLAS has expanded its reach to the southern hemisphere from the two existing northern-hemisphere telescopes on Haleakalā and Maunaloa in Hawai’i to include two additional observatories in South Africa and Chile.

VANDENBERG SPACE FORCE BASE, Calif. (NASA PR) — NASA will provide coverage of the upcoming prelaunch and launch activities for the agency’s first planetary defense test mission, the Double Asteroid Redirection Test (DART). The mission will help determine if intentionally crashing a spacecraft into an asteroid is an effective way to change its course. DART’s target asteroid is not a threat to Earth.

DART is scheduled to launch no earlier than 1:20 a.m. EST Wednesday, Nov. 24 (10:20 p.m. PST Tuesday, Nov. 23) on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

Small Asteroid to Safely Fly by Earth

WASHINGTON (NASA PR) — A relatively small asteroid, about 4 to 8 meters in diameter, will fly safely past Earth just before 3 pm today, Apr. 28 (Eastern U.S. time). NASA is tracking the object, but orbit calculations ruled out any chance that the near-Earth object could pose a threat to our planet.
