When humans return to the Moon they’ll have formidable challenge lying in wait: lunar dust. The talcum-like lunar regolith is considered the biggest operational problem facing Moon colonists. Within a few days of dust exposure, Apollo spacesuits suffered obscured visors, clogged mechanisms and eroded suit layers. So an ESA team is looking into novel materials options to serve as the basis of future spacesuits or protect rovers or fixed infrastructure.
