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

The new worlds observer: The astrophysics strategic mission concept study
EPJ Web of Conferences, 2011 We present some results of the Astrophysics Strategic Mission Concept Study for the New Worlds Observer (NWO). We show that the use of starshades is the most effective and affordable path to mapping and understanding our neighboring planetary systems, to

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 ...

Diagnosing Merely Verbal Disputes: A Case Study on Personal Identity
Metaphilosophy, EarlyView.Abstract Merely verbal disputes have attracted considerable attention in metaphilosophy. Yet the critical task of discussing workable diagnostic methods for determining which disputes are merely verbal has been largely neglected, and detailed case studies of philosophical debates are rare. This paper addresses both of these gaps.

Photochemistry and Photobiology, EarlyView.Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.
