Echo II
Launched from Vandenberg Air Force Base on January 25, 1964, Echo II conducted communication, atmospheric drag, and air density experiments. Inserted into Earth orbit in a metal canister, Echo II inflated into a large reflective balloon. Like Echo I, the satellite was used to perform passive communications experiments by bouncing radio signals from one ground station to another.
