The U.S. Air Force launches the first active-relay communications satellite into orbit, Courier 1B (the original Courier 1 having been lost to a faulty launch vehicle earlier). Unlike the reflective Echo 1 satellite, Courier 1B uses power from the solar cells covering its spherical casing to reboost and retransmit the signals it receives from Earth. Once again, a message from President Eisenhower is transmitted, this time to be received by the United Nations. Clourier 1B remains functional for just over two weeks before a glitch renders it useless.
