Here’s some UAV footage from last year. Spectacular and informative! An overhead look gives us a similar point of view to our Mars orbiters looking at similar features on the red planet, helps us map the properties of the lava, and contextualizes other data we've gathered. pic.twitter.com/B1l9AWLSKd

Team Topography uses Light Detection And Ranging (LiDAR) and Unmanned Aerial Vehicles (UAVs) to map the volcanic landscape. The team is observing how a new volcanic vent cools and erodes to better understand ancient features on the Moon and Mars. pic.twitter.com/IfaRjh9Q04

We’re the Goddard Instrument Field Team. We were in Iceland studying volcanic processes to discover what volcanic landscapes might be like on other planets and to figure out what specialized equipment we should bring when we explore our solar system. Here's a week in our lives. pic.twitter.com/WSmRquXLOu
