Mineralogical characterization of potential targets for the ASTEX mission scenario

► Four low-Δv Near-Earth asteroids (NEAs) were observed to select targets for ASTEX mission. ► The mission aims to land two landers for in-situ characterization of compositionally distinct (primitive and thermally evolved) NEAs. ► Of the four, two NEAs (1991 JW and 1998 PA) had compositions similar to ordinary chondrite meteorites, but two others (1994 CC and 1999 TA10) are thermally evolved objects.
