  1. Tools for Asteroid Regolith OperationsAsteroid Initiative Idea Synthesis Workshop, Houston, Sept. 30 – Oct. 2. Robert P. Mueller, Carlos I. Calle, PhD James G. Mantovani, PhD Surface Systems Office, NE-S NASA Kennedy Space Center Florida, USA

  2. Technologies Utilizing: • ELECTRODYNAMIC DUST SHIELD, • PNEUMATIC REGOLITH RAKE, • PERCUSSIVE EXCAVATION SHOVEL For Crew Asteroid Exploration 2 IMAGE CREDIT: heavyequipment.com

  3. Electrodynamic Dust Shield for Asteroid Mission EDS on Fabric Before activation After activation • Electrodynamic Dust Shield: Active multilayer coating that removes dust from surfaces • EDS for Visors, optical devices, viewports—transparent ITO electrodes on film, plastic, or glass • EDS for spacesuits: CNT electrodes printed on fabric • EDS for thermal radiators: 1000 Å copper electrode layer on Kapton film coated with thermal paint—silver electrode layer on FEP for second surface mirrors EDS on Film EDS Video EDS on Glass Reduced Gravity Flight Tests Apollo 16 dust removal at vacuum on Reduced Gravity Flight POC: Dr. Carlos I. Calle, NASA KSC

  4. Pneumatic Regolith Rake Pneumatic Excavation and Acquisition of Regolith Pneumatic Conveyance of Regolith (demonstrated to convey 17 kg)

  5. Percussive Excavation Shovel 5

  6. Conclusion Astronauts working with Asteroid regolith will need protection from dust and dust mitigation for payloads and instruments The Electrodynamic Dust Shield is at TRL 6 and available for mission infusion Astronauts collecting dust will need tools that facilitate the operation while increasing his/her work capacity The Pneumatic Regolith Rake allows the crew to collect loose surface regolith from a distance – application possible for ARM sample collection The Pneumatic Regolith Rake is at TRL 3 The Percussive Excavation Shovel allows trenching and deep regolith sample collection by an astronaut on an asteroidal surface with reduced reaction forces The Percussive Excavation Shovel is at TRL 4 Please contact the NASA KSC Surface Systems Office for more information
