NASA is gearing up to test an innovative new robot built to explore some of Earth's most inhospitable places: the fiery heart of volcanoes. <\/p>\n
Engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, are gearing up to drop VolcanoBot 2 inside Hawaii's active Kilauea volcano in March to create a 3D map of its fissures and crevices. And the hardy robot may one day help scientists explore volcanoes on other worlds. <\/p>\n
VolcanoBot 2, and its predecessor VolcanoBot 1, are designed to fit inside crevices in volcanoes that are too small or too dangerous for humans to explore. The robots are the brainchild of Carolyn Parcheta, a volcanist and NASA postdoctoral fellow based at JPL. <\/p>\n
\"We've never had a chance to measure a volcanic conduit before because they usually get buried or destroyed during an eruption,\" Parcheta said in her project's entry in a National Geographic Expedition contest. <\/p>\n
But Parcheta found two preserved, inactive fissures in the active Kilauea volcano in Hawaii. She and her JPL co-advisers, Aaron Parness and Karl Mitchell, already tested VolcanoBot 1. <\/p>\n
In May, NASA sent VolcanoBot 1 down 82 feet (25 meters) to two locations on the fissure. The wheeled robot is about 12 inches (30 centimeters) long with wheels that are 6.7 inches wide (17 cm). <\/p>\n
\"In order to eventually understand how to predict eruptions and conduct hazard assessments, we need to understand how the magma is coming out of the ground,\" Parcheta said in a NASA statement. \"This is the first time we have been able to measure it directly, from the inside, to centimeter-scale accuracy.\" <\/p>\n
The scientists found, however, that VolcanoBot 1 was too large and it's motors too weak to reach the fissure's bottom. Therefore, VolcanoBot 2 was born. <\/p>\n
With its length of 10 inches (25 cm), VolcanoBot 2 is smaller and lighter than its predecessor, with features that allow it to look up, down and around a fissure. <\/p>\n
Data will be collected and stored onboard VolcanoBot 2, and the robot's 3D live- video feed will allow Parcheta and her colleagues to navigate its path more accurately. <\/p>\n
