Can an astronaut occupy a space uncovered by the Drill before the Underground Hall token is built?

Question

Accepted Answer

No. The blue drill token only digs. The corporation action that builds the hall is what makes room for astronauts, so the uncovered slot is not usable until the hall is built.
