Dr. Carlos Calle, lead scientist in the Electrostatics and Surface Physics Laboratory at NASA's Kennedy Space Center in Florida, prepares an Electrostatic Dust Shield for testing on Thursday, July 19, 2018. Scientists are developing the Electrostatic Dust Shield to help mitigate the problem of dust on equipment, astronauts' space suits and helmet visors of astronauts exploring the Moon or Mars. The device is slated for analysis aboard International Space Station in the spring of 2019 to verify the effects of the space environment.
