Characterization of near-Earth objects (NEOs) is critical for Earth-impact hazard assessment. Particularly crucial to our physical understanding of NEOs are laboratory spectral measurements of meteorites as they are the best and most widely available

Since the dawn of the Space Age, hundreds of payloads have been launched into heliocentric space. As near-Earth object (NEO) surveys search deeper for small asteroids, more artificial objects in heliocentric orbits are being discovered. We now face a

The Earth’s most stable quasi-satellite, Kamoʻoalewa, displays an extremely red reflectance spectrum typical of space weathering of lunar-like silicate material which raises the possibility that it is formed of material originating from the Moon

The surface of active asteroid (3200) Phaethon, parent body of the Geminid meteor shower, reaches temperatures sufficient to destabilize hydrated materials. Here, the authors show that the northern hemisphere and the equatorial region of this asteroi

Ejecta from Dimorphos following the DART mission impact significantly increased the brightness of the Didymos–Dimorphos system, allowing us to examine subsurface material. We report daily near-IR spectroscopic observations of the Didymos system usi

We collect near-infrared spectra (∼0.75–2.55 μ m) of four Jovian irregular satellites and visible spectra (∼0.32–1.00 μ m) of two Jovian irregular satellites, two Uranian irregular satellites, and four Neptune Trojans. We find close similar

On 2022 March 4, the object known as WE0913A crashed into the Moon after several close flybys of the Earth and the Moon in the previous three months. Leading up to impact, the identity of the lunar impactor was up for debate, with two possibilities:
