Commemorative Envelope signed: "Al Worden" and "Jim Irwin", 6½x3¾. Commemorative Cover for the Apollo 15 mission, 8-cent United States flag stamp affixed, postmarked Cape Canaveral, Florida, August 2, 1971. The Apollo 15 mission, whose lunar module, Falcon, landed on the Moon on July 30th, was the first designed to explore the Moon over longer periods, greater ranges and with more instruments for the collection of scientific data than previous missions. To accomplish these goals, the mission included the introduction of a $40 million lunar roving vehicle, which reached a top speed of 10 mph across the Moon's surface. Irwin, who was the Lunar Module Pilot, and astronaut Dave R. Scott, who was the Commander of the mission, rode over 17 miles on the Moon as Command Module Pilot Al Worden orbited overhead in the Endeavor. Their lunar liftoff on August 2nd was the first to be televised. Apollo 15 returned to Earth on August 7, 1971. Air Force test pilot JAMES BENSON "JIM" IRWIN (1930-1991) was the Lunar Module Pilot on the Apollo 15 mission, walking and riding on the Moon. Moved by his experience in space, Irwin resigned from NASA and the Air Force in 1972 to form an evangelical Christian organization, the High Flight Foundation. In 1982, he led an ascent to the summit of Mount Ararat in an unsuccessful search for Noah's Ark.  ALFRED MERRILL "AL" WORDEN (1932-2020) was serving in the U.S. Air Force when he was among the 19 astronauts selected by NASA in April 1966. A member of the astronaut support crew for Apollo 9 and the backup command module pilot for Apollo 12, Worden was the command module pilot for Apollo 15. He logged 38 minutes of EVAs outside the "Endeavor". Worden was later President of Maris Worden Aerospace, Inc. and Vice President of BF Goodrich Aerospace (Bucksville, Ohio). Slightly creased.
