First Tests for the VERITAS' Venus Interferometric Synthetic Aperture Radar

Seen here in March 2023, prototype hardware for the Venus Interferometric Synthetic Aperture Radar (VISAR) underwent interface testing at NASA's Jet Propulsion Laboratory in Southern California. VISAR is being developed at JPL for NASA's Venus Emissivity Radio Science, InSAR, Topography & Spectroscopy (VERITAS) mission that will launch within a decade to explore Earth's twin. These early interface tests are the first in a series to be run by JPL and Thales Alenia Space Italy (TASI), an international partner of the VERITAS mission that is contributing hardware to the instrument. Figure A shows TASI engineers Luca Di Marco Napini and Gabriel Mihu working in a JPL cleanroom on the VISAR prototype hardware. When VERITAS arrives in orbit, it will use VISAR to create detailed 3D global maps of Venus. The spacecraft will also carry a near-infrared spectrometer to figure out what the surface is made of. Together, the instruments will offer clues about the planet's past and present geologic processes, help reveal how the paths of Venus and Earth diverged, and how Venus lost its potential as a habitable world. VERITAS is managed by JPL. VERITAS and NASA's Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission were selected in 2021 under NASA's Discovery Program as the agency's next missions to Venus. The Discovery Program is managed by the Planetary Missions Program Office at NASA's Marshall Space Flight Center in Huntsville, Alabama, for the Planetary Science Division of NASA's Science Mission Directorate in Washington. https://photojournal.jpl.nasa.gov/catalog/PIA25832
