The Yggdrasil civilization has already done some investigation into the Umbra world. This is where the information he was given before the expedition came from.
But that information is outdated. Even if it isn't, there might be danger around, which is why scouting is needed and also why it is dangerous to scout.
But he is confident of keeping his life, so he took the mission. His armor created a force field around him that prevented the cold winds from reaching him.
His tactical goggles helped him to see in the dark. He doesn't need it, but it will be very important for other soldiers in this perpetually cold, dark world.
The reward for this mission is based on how much ground he covers and what he discovers. So his speed force ability will be able to earn him a lot of merit points.
He said confidently, "I bet I can cycle the world many times in a day."
