Benner: We describe radar observations of near-Earth asteroids (NEAs) at Goldstone since resumption of operations in 2020. Since 2020, we have observed 199 NEAs, 154 for the first time, 112 that are "Potentially Hazardous Asteroids," and 19 binary systems. #LPSC2025

Benner starts out with this image from Goldstone of 887 Alinda taken just two months ago.

Benner: Priority of NEA observations is now higher at Goldstone. Much more time allocated. Improvements have made it more reliable, and there is greater scheduling flexibility.

Benner: ~5-fold increase in Goldstone NEA radar detections in the last 15 years. Observed 55 objects in 2024, over one a week, up from nine in 2020.

Benner: Goldstone has had 210 total near-Earth asteroid detections since 2020, that includes 18 binaries, with 14 of those discovered at Goldstone.
