Meteoritics &Planetary Science, EarlyView.Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Asteroid resource map for near-Earth space [PDF]
, 2011 Most future concepts for the exploration and exploitation of space require a large initial mass in low Earth orbit. Delivering this required mass from the Earth’s surface increases cost due to the large energy input necessary to move mass out of the ...

Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)
Meteoritics &Planetary Science, EarlyView.Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...

Utopia Remembers: The Soviet Past in the Imagined Communist Future
The Russian Review, EarlyView.Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.

BYORP and Dissipation in Binary Asteroids: Lessons from DART
The Planetary Science JournalThe near-Earth binary asteroid Didymos was the target of the planetary defense demonstration mission DART in 2022 September. The smaller binary component, Dimorphos, was impacted by the spacecraft in order to measure momentum transfer in kinetic impacts ...

The Perturbed Full Two-body Problem: Application to Post-DART Didymos
The Planetary Science Journal, 2023 With the successful impact of the NASA Double Asteroid Redirection Test (DART) spacecraft in the Didymos–Dimorphos binary asteroid system, we provide an initial analysis of the post-impact perturbed binary asteroid dynamics.

Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
The Astrophysical Journal Letters, 2023 The impact of the Double Asteroid Redirection Test spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos’s orbit substantially, largely from the ejection of material.

DART Impact Ejecta Plume Evolution: Implications for Dimorphos
The Planetary Science JournalThe NASA Double Asteroid Redirection Test (DART) spacecraft impacted the moon Dimorphos of the [65803] Didymos binary system and changed the binary orbit period, demonstrating asteroid deflection by a kinetic impact and indicating that more momentum was ...
