Quick Thinking Demonstrated Value of the Human Element

By Bob Granath | July 1, 2024

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.

Why Do We Explore?

By Bob Granath | March 18, 2022

Throughout history, humankind has shared an innate trait – the desire to explore. Prehistoric men and women may have stood curiously at the opening of caves and wondered what was over the next hill. Centuries later, a teenager in New England envisioned a trip to a distant planet. With the rollout of NASA’s Space Launch System (SLS) mega-rocket and Orion spacecraft, the agency now is preparing a return to the Moon as a steppingstone to an eventual expedition to Mars.

Gemini XII Crew Masters the Challenges of Spacewalking

By Bob Granath | November 23, 2021

In the 20 months following the first piloted Gemini mission, NASA astronauts demonstrated the ability to change orbits, perform rendezvous and docking, along with spending up to two weeks in space. Spacewalking, on the other hand, remained an enigma. With only one more Gemini flight on the schedule, solving the problems of working outside a spacecraft would be the primary goal for Gemini XII.

Demanding Gemini XI Mission Flies on Top of the World

“I tell ya from up here the world is round. It is spectacular. It’s fantastic,” said Gemini XI command pilot Pete Conrad as he and pilot Dick Gordon looked down from their lofty vantage point. Their record-shattering altitude of 850 miles above the Earth was only one highlight of a demanding, three-day mission in September 1966 – 55 years ago.

Grissom’s Mission Demonstrated Spaceflight is a Perilous Endeavor

By Bob Granath | July 14, 2021

In the summer of 1961, NASA was ready to launch its second piloted spaceflight. It was the next step in Project Mercury’s program to study human capabilities during space travel. Two months earlier, Alan Shepard’s textbook sub-orbital mission made it look easy. But, the splashdown and recovery of the encore flight dramatically demonstrated it is a perilous endeavor requiring attention to detail and extensive preflight training.
