When researcher Alberto Behar from NASA's Jet Propulsion Laboratory in Pasadena, Calif., joined an international Antarctic expedition last month on a trek to investigate a subglacial lake, he brought with him a unique instrument designed and funded by NASA to help the researchers study one of the last unexplored aquatic environments on Earth. • Called the Micro-Submersible Lake Exploration Device, the instrument was a small robotic sub about the size and shape of a baseball bat. Designed to expand the range of extreme environments accessible by humans while minimally disturbing the environment, the sub was equipped with hydrological chemical sensors and a high-resolution imaging system. The instruments and cameras characterize the geology, hydrology and chemical characteristics of the sub's surroundings. Behar supervised a team of students from Arizona State University, Tempe, in designing, developing, testing and operating the first-of-its-kind sub. • This is the first instrument ever to explore a subglacial lake outside of a borehole, Behar said. It's able to take us places that are inaccessible by any other instruments in existence. • Read the full story at: https://www.discovermagazine.com/the-... • — • Video courtesy NASA/JPL • — • • ABOUT DISCOVER: • Discover is your source for science that matters, makes sense and is a lot of fun, too. • Visit us at: http://www.discovermagazine.com/ • • FOLLOW US: • Facebook: / discovermag • Twitter: / discovermag • Instagram: / discover.magazine • • SUPPORT US: • Subscribe to Discover: https://bit.ly/34seAFT • Sign up for our newsletter: https://www.discovermagazine.com/news... • My Science Shop: https://www.myscienceshop.com/ • • STAY CURIOUS!
