Moon dust, or lunar regolith, is sharp and clingy. NASA’s account warns that without mitigation it could damage spacesuits and equipment and pose health risks to astronauts. Its electrostatic properties can also change with lighting and environmental conditions, making an understanding of its behavior essential to safe surface work. [S1]

For crews and rover operations near the lunar South Pole, the communications problem begins with visibility: rugged terrain can block a clear line of sight to Earth. NASA says relay infrastructure will be needed to carry signals across the region. The planned connection is therefore part of the support astronauts will need to work on that terrain. [S1]
