Option 1 -> Directly stated in the passage as the critical purpose of space docking technology.
Option 2 -> Not mentioned; ground control remains essential for space missions.
Option 3 -> Space docking is unrelated to preventing debris formation; the passage mentions re-purposing debris separately.
Option 4 -> Space docking involves orbital operations, not launch vehicle construction.
Hence, Option 1 -> The passage explicitly states that "mastering it is critical for missions that involve assembling large structures in orbit or servicing satellites," and also mentions its pivotal role in future space station operations and deep-space explorations -> correct
