- Roger Wiens
Technical Staff Member in the Space and Atmospheric Science Division
- Roger Wiens is a Technical Staff Member in the Space and Atmospheric Science Division at LANL.
- He is a co-investigator and LANL Project Leader for the Genesis Discovery Mission.
- Wiens has significant responsibilities in project leadership, development of the large-aperture solar wind concentrator, and in the collector material selection and testing.
- He is the science analysis co-investigator for DS-1's PEPE (Plasma Experiment for Planetary Exploration). With an emphasis on plasma interaction with small asteroids.
- He is also co-investigator on a Mars Instrument Development Project to produce and test a prototype Laser-Induced Breakdown Spectroscopy (LIBS) instrument capable of rapidly determining elemental composition of planetary surfaces anywhere within 60 feet of a rover or lander.
- Co-investigator on an internal project to develop a LIBS companion instrument using Laser-Induced Mass Spectrometry (LIMS), which could determine isotopic compositions of planetary surfaces anywhere within 60 ft of a rover or lander.
