Hydrothermal vent research. Technician in a laboratory used to simulate the conditions found at an underwater hydrothermal vent. This lab is being used to test whether organic molecules can be 'brewed' in a simulated vent with conditions similar to the circulation found at the bottom of an ocean on the early Earth or the icy moons orbiting Jupiter or Saturn. Photographed at NASA's Jet Propulsion Laboratory, California, USA.
