Captain Chuck Yeager Becomes Fastest Man Alive

At the end of World War II, the U.S. National Advisory Committee for Aeronautics, working separately with the Navy and Air Force, began working on different approaches to attaining high-speed flight. Bell Aircraft Corporation, using engines by Aerojet Engineering Corporation, won the contract to build three X-1 aircraft. The X-1 was no normal airplane; it was a rocket, fueled with liquid oxygen and alcohol propellants and driven by a 6,000-pound-thrust engine. To conserve fuel, the X-1 would be carried aloft by a specially fitted B-29 bomber and released.

On October 14, 1947, Captain Chuck Yeager of the U.S. Air Force piloted his Bell X-1, the Glamorous Glennis, to a speed of Mach 1.07, becoming the first person to break the sound barrier. Being the first country to fly faster than the speed of sound was a matter of national prestige, and further bolstered aeronautical testing and innovation.

Alan Shepard’s Space Flight Changed the Course of History

Today marks the 51st anniversary of the first manned American space flight as part of NASA’s Project Mercury.

Initiated in 1958, Project Mercury was the nation’s program to send humans into orbit around the Earth.  The previous year the Soviet Union, America’s Cold War rival, had startled the world by using an intercontinental missile to launch Sputnik, history’s first artificial satellite. This achievement marked the dawn of the space age and spurred an intensely watched space race between the two superpowers.

In 1959, NASA selected the nation’s first astronauts. After screening 110 top military test pilots, NASA chose seven men whose names would soon become known to the world: Scott Carpenter, Gordon Cooper, John Glenn, Gus Grissom, Wally Schirra, Alan Shepard, and Deke Slayton.

After nearly two years of rigorous training, Alan Shepard was chosen in a vote by his fellow Mercury astronauts to be the first American in space.

The Mercury spacecraft—Shepard’s was named Freedom 7—was barely large enough to accommodate an average-sized man. The blunt end of the cone-shaped capsule was covered by a shield designed to survive the intense heat from re-entry into the atmosphere. Shepard and the other astronauts influenced several elements of the spacecraft’s design, including the addition of a window for taking star sightings and an option to operate the vehicle manually.

The launch vehicle was a seven-story-tall Redstone rocket developed by an engineering team headed by Wernher von Braun. The Redstone was chosen for its record of reliability, but it was only powerful enough to achieve a suborbital flight.

As the world watched on television, Shepard blasted off from Cape Canaveral, Florida, on May 5, 1961. The flight reached a maximum speed of 5,100 miles per hour, roughly eight times the speed of sound, and a zenith of 116 miles above the Earth. With parachutes deploying, it safely splashed down in the Atlantic some 300 miles from the launch site. The New York Times declared that Shepard’s 15-minute flight “roused the country to one of its highest peaks of exultation since the end of World War II.”

Project Mercury set the country on a path that would lead to the stunning Apollo 11 moon landing eight years later on July 20, 1969, the crowning technological achievement of the 20th century.

In 2011, the Postal Service issued two stamps in recognition of advances in space exploration. The Mercury Project and MESSENGER Mission stamps were issued as Forever® stamps and are still available!

10 Stamps for Space Day

Held on the first Friday of May since 1997, Space Day is dedicated to the celebration of the great achievements in space travel and exploration, and promoting education about the vastness that lies beyond. My interest in space has always been a mixture of fascination and awe. Science was never my subject, but learning about space and imagining other worlds still provides endless enjoyment, especially when I’m learning about through stamps!

In honor of Space Day, I’m sharing my 10 favorite space-themed stamps (it was hard to narrow them down!) and what they’ve taught me about the final frontier.

In 1962, aboard the Mercury Friendship 7, John Glenn became the first American to orbit Earth. His 1998 return to space at age 77, on the shuttle Discovery, heightened interest in the space program.

NASA’s Hubble Space Telescope imaged an eerie cradle of star formation called the Lagoon Nebula. The giant clouds of dusty gas may have been shaped by high-speed interstellar winds created within the clouds by newly formed stars.

The extended, close-range observation of Saturn by the Voyager 2 satellite in the 1980s provided NASA in depth information on the ringed planet for the first time.

Reminiscent of the 1930s vision of space travel made popular in movies and comic book adventures, this fantasy of futuristic space life brings a sense of whimsy and imagination to the somewhat terrifying notion of one day living in space.

Launched March 1972, Pioneer 10 was the first spacecraft to travel to Jupiter and send back data and images.  Eleven years later, it became the first man-made object to leave the solar system.

Traveling 218,096 miles, astronauts Neil Armstrong and Edwin Aldrin immortalized themselves in history when they became the first men to walk on the moon in 1969.

From colonizing remote planets to building lunar bases to zooming through the stars, we have pictured a variety of outer space adventures, many of which have been realized. Perhaps one day a base like this imagined one will not seem like such a fantasy.

The Postal Service’s first round stamp, the hologram image of the Earth in the center pays tribute to the great achievements of the American space program.

The Palomar Observatory in San Diego County, California, houses five telescopes that are nightly used to conduct astronomical research and collect data. An essential component to space exploration, telescopes let us view the solar system from Earth long before we broke through the atmosphere.

It is truly amazing what humans have accomplished in outer space. Though the space shuttle age is over, we’ve only just begun to discover what lies beyond our world.
