'Valkyrie' is a large landing craft that travels between space orbit and Pandora, and it also serves as the bridge between the spacecraft 'Pioneer Star' and Pandora.
The 'Pioneer Star' could be described as the culmination of human technology in this world, with controlled nuclear fusion and antimatter application, neural network connection, will transmission, and so forth—all converged into one.
But in essence, Pioneer Star was just a freighter, shuttling back and forth transporting the room temperature superconductive materials refined on Pandora.
Also, due to limited transport capacity, no excessive space could be wasted. Therefore, the superconductive mines on Pandora Planet had to be refined locally, resulting in bases on the surface centered around the gigantic Valkyrie landing crafts.
This base itself had even achieved industrialization, capable of mining and producing some relevant equipment on its own—a true representation of interstellar civilization.
