The JPL-led international team used the island as a stand-in for Venus to test radar technologies that will help uncover the planet’s ground truth. With its crushing atmospheric pressure, clouds of sulfuric acid, and searing surface temperature, Venus is an especially challenging place to study.
of southwestern Iceland. The barren and rocky landscapes of both resemble Venus’ surface, which is thought to be rejuvenated by active volcanism.
Using a tripod-mounted lidar scanner, the science team created this image that highlighted the ropy texture of new rock formed by a recent lava flow near Iceland’s Litli-Hrútur volcano. This will be used to compare with the campaign’s airborne radar images of the same region. Credit: NASA/JPL-Caltech

A DLR field team also collected compositional information with a camera that emulates the Venus Emissivity Mapper instrument the German Aerospace Center is building for VERITAS. This data will support the spectral library being created at the Planetary Spectroscopy Laboratory in Berlin.

Scientists Discover Source of Mysterious Earth TremorsNew research has confirmed that fracking is responsible for the previously unexplained slow, small earthquakes or tremors. The tremors are produced by the same processes that could create large, damaging earthquakes. Fracking involves the forceful injection of fluids below the Earth's surface to
