Pioneer 10, the world’s first outer-planetary probe,was
launched from Cape Canaveral, Florida, on a mission to
Jupiter, the solar system’s largest planet, on this day
in 1972.

In December 1973, after successfully negotiating the
asteroid belt and a distance of 620 million miles,
Pioneer 10 reached Jupiter and sent back to Earth
the first close-up images of the spectacular gas giant.

In June 1983, the NASA spacecraft left the solar system
and the next day radioed back the first scientific data on
interstellar space. NASA officially ended the Pioneer 10
project on March 31, 1997, with the spacecraft having
traveled a distance of some six billion miles.

On this day in 1969, Apollo 11, the U.S. spacecraft that had taken the
first astronauts to the surface of the moon, safely returned to Earth and splashed down in the Pacific Ocean.

United States President Richard Nixon was in the central Pacific recovery area
to welcome the Apollo 11 astronauts aboard the USS Hornet, prime recovery
ship for the historic Apollo 11 lunar landing mission, on July 24, 1969. The
Apollo 11 astronauts are, from left, Neil Armstrong, Michael Collins and Buzz
Aldrin. They were quarantined after splashdown to ensure they did not bring
back any contamination from the moon.

On this day in 1969, Apollo 11 made thirty orbits of the moon which allowed
them to view the landing site: the southern Sea of Tranquility, one of the
most suitably flat areas. This area had confirmed by the Apollo 10 ‘dress
rehearsal’ mission in which the crew captured vital film footage and photos 
while orbiting the moon.

and began the first manned mission to land on the moon.

On this day in 1997, U.S. Air Force officials release a 231-page report
dismissing long-standing claims of an alien spacecraft crash in Roswell,
New Mexico, almost exactly 50 years earlier.

Public interest in Unidentified Flying Objects, or UFOs, began to flourish
in the 1940s, when developments in space travel and the dawn of the
atomic age caused many Americans to turn their attention to the skies.

The town of Roswell, located near the Pecos River in southeastern New
Mexico, became a magnet for UFO believers due to the strange events of
early July 1947, when ranch foreman W.W. Brazel found a strange, shiny
material scattered over some of his land. He turned the material over to
the sheriff, who passed it on to authorities at the nearby Air Force base.

On July 8, Air Force officials announced they had recovered the wreckage
of a “flying disk.” A local newspaper put the story on its front page,
launching Roswell into the spotlight of the public’s UFO fascination.
