Question

collect the information about space mission procedure​

Answer 1

Answer:  The spacecraft enters or leaves Earth orbit and heads for its destination.

NASA, through use of the Deep Space Network or other radio telescopes, stays in contact with the spacecraft, uplinking commands and downlinking information about the spacecraft and data about what the spacecraft is encountering.

The spacecraft goes into "encounter" phase, where it is in contact with something in space worth studying. It could orbit, fly by or land on the object it is encountering. Experiments are done by the spacecraft.
