It is, he claims, an uneventful routine.
Wilson’s expedition is well equipped. Traveling from the main lunar base, some five hundred miles away, the crew is laden with heavy equipment, including overland tractors, rockets, and scientific sampling machinery. It appears they have little to fear from the unknown. They are in constant radio contact with their base and can survive for a month in their pressurized tractor cabins if there were an emergency.
The men live in relative comfort during their tour of duty on the moon. Short wave radio contact with earth provides ubiquitous music for the men as they dine on freshly cooked food.
