Can a falling object reach terminal velocity in outer space? explain.

Ith air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (195 km/h or 122 mph) for a human skydiver. ... (On the Moon, the gravitational acceleration is much less than on Earth, approximately 1.6 m/s2.)

It equals just about 6,300 km per hour each day an week

Because its reliable.   there is no pollution  the chances of a radiation leak is low
