Asteroid Kamo‘oalewa’s journey from the lunar Giordano Bruno crater to Earth 1:1 resonance

Nature Astronomy
Among the nearly 30,000 known near-Earth asteroids (NEAs), only tens possess Earth co-orbital characteristics with semi-major axes ~1 au. In particular, 469219 Kamo‘oalewa (2016 HO3), an upcoming target of China’s Tianwen-2 asteroid sampling mission ...

Detection of a climate-induced increase in the lunar recession rate

Astronomy & Astrophysics
Gravitational interplay between the Earth and Moon is believed to steadily increase the length of day (ΔLOD) and cause a secular drift of the Moon away from the Earth (lunar recession).

Neuromorphic Cameras in Astronomy: Unveiling the Future of Celestial Imaging Beyond Conventional Limits

arXiv.org
To deepen our understanding of optical astronomy, we must advance imaging technology to overcome conventional frame-based cameras' limited dynamic range and temporal resolution.

The Dawning of Radio Astronomy from the Moon

United States National Committee of URSI National Radio Science Meeting
The first robotic commercial lunar lander, Intuitive Machines' Odysseus, successfully touched down on the Moon in the South Pole region on 22 February 2024. This mission was part of NASA's Commercial Lunar Payload Services (CLPS) program.

A synthesis arrary for lunar submillimeter astronomy

AIP Conference Proceedings, 1990
This paper describes a system concept for a Synthsis Array for Lunar Submillimeter Astronomy (SALSA). It includes a brief discussion of the science objectives and the advantages of placing such an array on the moon, the system concept, and a top‐level discussion of the various subsystems, including the technology drivers associated with each.

ARCSEC source location measurements in gamma-ray astronomy from a lunar observatory

AIP Conference Proceedings, 1990
The physical processes typically used in the detection of high energy γ rays do not permit good angular resolution, which makes difficult the unambiguous association of discrete γ‐ray sources with objects emitting at other wavelengths. This problem can be overcome by placing γ‐ray detectors on the Moon and using the horizon as an occulting edge to ...

The Lunar Observer radio astronomy experiment (LORAE)

2008
We propose to place a simple low frequency dipole antenna on board the Lunar Observer (LO) satellite. LO will orbit the Moon in the mid-1990's, mapping the surface at high resolution and gathering new geophysical data. In its modest concept, LORAE will collect crucial data on the radio interference environment while on the near-side (to aid in planning
