As NASA’s Moon rocket thundered into the Space Coast sky, it heralded a renewed era of human exploration. The agency’s Artemis II mission begins an effort to learn how to live and work on another world in preparation for pioneering missions to Mars. During the 10-day flight, the four-person crew will circle around the Earth’s neighbor, traveling farther away than any astronauts during the Apollo Program of the 1960s and 1970s.
In late 1966, the final Gemini mission was launched into the skies over Cape Kennedy Air Force Station. At Mission Control in Houston, Dr. Chris Kraft, NASA’s director of Flight Operations, turned to Dr. Robert Gilruth, director of the agency’s Manned Spacecraft Center, and said, “Thank God we never had to use those ejection seats.” But, if not for a test pilot’s quick thinking, two astronauts would have during an attempt to launch a Gemini mission a year earlier.
“I’m having a ball up here drifting,” said NASA astronaut Wally Schirra as he orbited the Earth six times during the Mercury-Atlas 8, the agency’s fifth manned space flight — 60 years ago. He proved that if the pilot was allowed to take control of the flight, he could conserve fuel and solve problems as they arise.
In December 1968, the crew of Apollo 8 became the first humans to leave Earth orbit and head for the Moon. They also became the first to look back at their home planet and see the entire world in one glimpse. The view they shared had an everlasting impact. In the decades since humans have looked back at their home planet from the vantage point of space, astronauts have taken stunning photographs providing a new perspective of Earth and its place in the universe.
The flights of two piloted spacecraft during December 1965 were major strides forward in advancing NASA’s capabilities in human spaceflight. While Gemini VII orbited the Earth for two weeks, Gemini VI was launched, completing the first-ever rendezvous between two spacecraft in orbit. This marked the point in which the United States clearly pulled ahead in the space race with the Soviet Union.
On Dec. 21, 1968, NASA’s Mission Control gave the crew of Apollo 8 approval for TLI — trans-lunar injection — permission to become the first humans to leave Earth orbit. Their destination, 234,000 miles away, was the Moon.
