Sputnik 2:
It was the second spacecraft launched into Earth orbit and was the first biological spacecraft. It was a 4 meter high cone-shaped capsule with a base diameter of 2 meters. It contained several compartments for radio transmitters, a telemetry system, a programming unit, a regeneration and temperature control system for the cabin, and scientific instruments. A separate sealed cabin contained the experimental dog Laika. Engineering and biological data were transmitted using the Tral_D telemetry system, which would transmit data to Earth for 15 minutes of each orbit. Two spectrophotometers were on board for measuring solar radiation (ultraviolet and x-ray emissions) and cosmic rays. A television camera was mounted in the passenger compartment to observe Laika. The camera could transmit 100-line video frames at 10 frames/second.

Sputnik I was about the size of a basketball, weighed 183 pounds and took about 98 minutes to orbit Earth. Sputnik I was in orbit for six months before it fell back into the atmosphere.

Sputnik was as big as a garbage can!
You only need 5 watts to transmit from space to everywhere, and at low power, it didnt take much to "shock the World".
I wish you well..
