One Pinnacle of Human Achievement to Another: On April 12,
1961, cosmonaut Yuri Gagarin became the first human to reach Earth
orbit. Launching from Baikonur Cosmodrome on Vostok-1, he flew for
108 minutes and nearly circled the planet before landing in
Kazakhstan. From a porthole at his feet, he could view our blue
planet as a sphere. He declared: “It is indescribably
beautiful.”On April 12, 1981, astronauts John Young and Robert
Crippen rode the space shuttle Columbia into the sky, launching from
Cape Canaveral in the world's first reusable space vehicle. It was
the first time in history that a new spacecraft was launched on its
maiden voyage with a crew aboard. Thirty years and 513 million miles
later, the NASA space shuttle fleet—Discovery, Endeavour, Atlantis,
together with Columbia and Challenger (both lost)—has carried 350
people into orbit on 133 flights.
In honor of this double
anniversary, Earth Observatory offers this astronaut photograph of
part of the region where many historians say the march of
civilization began: the “Fertile Crescent” of the Middle East. Known
to many as “the cradle of civilization,” the stretch of land astride
the Tigris and Euphrates rivers nurtured several of the earliest
known cities and empires.
Astronauts on flight STS-1 captured this
view of Iran, Iraq, and Kuwait through a viewport on the space
shuttle on April 13, 1981. The photo was taken with a handheld camera
on the 15th orbit around Earth, during a flight that lasted 54
hours.
The space shuttle has “helped us improve communications on
Earth and understand our home planet better,” said NASA Administrator
Charles Bolden on April 12, 2011. “It's set scientific satellites
like Magellan and Ulysses speeding on their missions into the solar
system, and launched Hubble and Chandra to explore the universe. It's
enabled construction of the International Space Station, our foothold
for human exploration, which is leading to breakthroughs in human
health and microgravity research.”
It all started fifty years ago
this day. The United Nations has declared April 12 to be the
International Day of Human Space Flight.
