NEEMO20 Splashdown was yesterday…let the analog exploration begin! Check out the NEEMO 20 geology sampling tools! This sampling kit includes a number of end effectors for collection of surface samples, regolith samples, and rock chips & cores. The hand and power drivers used to operate the end effectors are pictured in the lower right. As part of this analog test the crew will also use a simulated geophysical array pictured in the upper right. The JSC NASA EVA tool team, with support from NASA_ARES science experts, have done a great job designing and making tools for the challenging underwater environment the NEEMO 20 crew will be operating in during the next two weeks.
