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.

Near-Earth Asteroid Might be a Lost Fragment of the Moon

TUCSON, Ariz. (University of Arizona PR) — A near-Earth asteroid named Kamo`oalewa could be a fragment of our moon, according to a paper published today in Nature Communications Earth and Environment by a team of astronomers led by the University of Arizona.

NASA Spacecraft Provides Insight into Asteroid Bennu’s Future Orbit

WASHINGTON (NASA PR) — In a study released Wednesday, NASA researchers used precision-tracking data from the agency’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to better understand movements of the potentially hazardous asteroid Bennu through the year 2300, significantly reducing uncertainties related to its future orbit, and improving scientists’ ability to determine the total impact probability and predict orbits of other asteroids.

The study, titled “Ephemeris and hazard assessment for near-Earth asteroid (101955) Bennu based on OSIRIS-REx data,” was published in the journal Icarus.

A Second Cable Fails at NSF’s Arecibo Observatory in Puerto Rico

Engineers are reviewing the new damage and assessing how to best stabilize the facility.

A main cable that supports the Arecibo Observatory broke Friday at 7:39 p.m. Puerto Rico time.

Unlike the auxiliary cable that failed at the same facility on Aug. 10, this main cable did not slip out of its socket. It broke and fell onto the reflector dish below, causing additional damage to the dish and other nearby cables. Both cables were connected to the same support tower. No one was hurt, and engineers are already working to determine the best way to stabilize the structure.

An SUV-size space rock flew past our planet over the weekend and was detected by a NASA-funded asteroid survey as it departed.

PASADENA, Calif. (NASA PR) — Near Earth Asteroids, or NEAs, pass by our home planet all the time. But an SUV-size asteroid set the record this past weekend for coming closer to Earth than any other known NEA: It passed 1,830 miles (2,950 kilometers) above the southern Indian Ocean on Sunday, Aug. 16 at 12:08 a.m. EDT (Saturday, Aug. 15 at 9:08 p.m. PDT).

Broken Cable Damages Arecibo Observatory in Puerto Rico

ARECIBO, PR (University of Central Florida PR) — One of the auxiliary cables that helps support a metal platform in place above the Arecibo Observatory in Puerto Rico, broke on Monday (Aug. 10) causing a 100-foot-long gash on the telescope’s reflector dish. Operations at the UCF-managed observatory are stopped until repairs can be made.
