Identifying LL Chondrite Near-Earth Asteroids Using LL Chondrite Reflectance Spectra
The Astrophysical Journal LettersMost near-Earth objects are thought to originate from the collisional fragments of the main asteroid belt. One question that remains to be resolved is the proportion of near-Earth objects sampling the core area material of the parent body to the outer ...

, 2014 An adaptive guidance algorithm for close approach to and precision landing on uncooperative low-gravity objects (e.g. asteroids) is proposed. The trajectory, updated by means of a minimum fuel optimal control problem solving, is expressed in a polynomial

Widespread Impact‐Induced Crustal Permeability on the Early Earth
AGU Advances, Volume 7, Issue 3, June 2026.Abstract The early Earth (i.e., Archean and Hadean Eons, 2.5–4.0 and 4.0–4.5 Ga, respectively) experienced frequent cosmic bombardment. Impacts have been shown to stimulate crustal alteration, for instance via hydrothermal systems active for up to millions of years post‐impact.
