Human missions to new destinations such as Near-Earth Objects - NEOs - and low gravity bodies are amongst the targets in the current roadmaps of space agencies like the ISECG Global Exploration Roadmap - NEO are an intermediate step stone for human exploration and technology demonstration beyond ISS in the ambition to bring humans to Mars. However, novel technologies need to be developed and validated that allow field exploration of the surface of a low-gravity body. The exploration and EVA on an asteroid by humans will look very differently than what was done during the exploration of the lunar surface in the frame of the Apollo Program. It might resemble rather to EVA in orbit as those performed on ISS today. The challenge however will be to develop an infrastructure that allows an astronaut to move over the surface of NEO, thus a natural, uncooperative surface.
ISS is equipped with specific interfaces that help astronauts to move along the hull of the station while being secured. Similar elements need to be developed that feature interfaces for human intervention but that can be deployed on the surface of low-gravity bodies by a robotic landing vehicle.
