On April 11, 1970, Apollo 13, the third lunar landing mission, was successfully launched from Cape Canaveral, Florida, carrying
astronauts James A. Lovell, John L. Swigert and Fred W. Haise.

After an oxygen tank exploded just over 200,000 miles from Earth
on the evening of April 13, however, the new mission objective
became to get the Apollo 13 crew home alive. The landing mission
was aborted.

On April 9, 1959, the National Aeronautics and Space
Administration (NASA) introduced America’s first
astronauts to the press: Scott Carpenter, L. Gordon
Cooper Jr., John H. Glenn Jr., Virgil “Gus” Grissom,
Walter Schirra Jr., Alan Shepard Jr. and Donald Slayton.

The seven men, all military test pilots, were carefully
selected from a group of 32 candidates to take part in
Project Mercury, America’s first manned space program,
planned to begin orbital flights in 1961.

While in orbit 170 miles above Earth, Navy Captain Bruce
McCandless II became the first human being to perform
an untethered spacewalk, when he exits the U.S. space
shuttle Challenger and maneuvers freely, using a bulky
white jet pack of his own design.

McCandless orbited Earth in tangent with the shuttle at
speeds greater than 17,500 miles per hour—the speed
at which satellites normally orbit Earth—and flew up to
320 feet away from the Challenger. After an hour and a
half of testing and flying the jet-powered backpack and
admiring Earth, McCandless safely reentered the shuttle.

At 11:38 a.m. EST, on January 28, 1986, the space shuttle
Challenger lifted off from Cape Canaveral, Florida, and
Christa McAuliffe is on her way to becoming the first
ordinary U.S. civilian to travel into space. McAuliffe, a
37-year-old high school social studies teacher from New
Hampshire, won a competition that earned her a place
among the seven-member crew of the Challenger.

Seventy-three seconds later, hundreds on the ground,
including Christa’s family, stared in disbelief as the
shuttle broke up in a forking plume of smoke and fire.

A launch pad fire during Apollo program tests at Cape Canaveral,
Florida, killed astronauts Virgil “Gus” Grissom, Edward H. White II,
and Roger B. Chaffee.

The astronauts, the first Americans to die in a spacecraft, had
been participating in a simulation of the Apollo 1 launch that 
was scheduled for the following month.

The Apollo 1 prime crewmembers intended for the first
manned Apollo space flight: (L to R) Edward H. White II,
Virgil I. "Gus" Grissom, and Roger B. Chaffee.
