launched in Boston Harbor. The a 44-gun U.S. Navy frigate,
built to fight Barbary pirates off the coast of Tripoli, performed commendably during those conflicts, and in 1805 a peace treaty
with Tripoli was signed on the Constitution‘s deck.

warship still afloat.

From the Atlantic Missile Range in Cape Canaveral, Florida,
the U.S. unmanned spacecraft Explorer 6 atop a Thor-Able
rocket was launched into an orbit around the earth.

The spacecraft, commonly known  as the “Paddlewheel”
satellite, featured a photocell scanner that transmitted a
crude picture of the earth’s surface and cloud cover from
a distance of 17,000 miles. The photo, received in Hawaii,
took nearly 40 minutes to transmit.

The first satellite image of Earth captured by Explorer 6 on August 14, 1959.

At 9:32 a.m. EDT, Apollo 11, the first U.S. lunar landing mission, 
was launched on a historic journey to the surface of the moon.

After traveling 240,000 miles in 76 hours, Apollo 11 entered into
a lunar orbit on July 19.
