Major Peake will gain in stature, and not just because of his elevated position: astronauts get a chance to walk tall in orbit.
I shall, at least, keep walking the perimeter of Pluto until my footsteps wear my orbit into the earth.
The gap between the tiny Mercury capsule, in which astronaut Alan Shepard had become the first American in space (but not even orbit) three weeks earlier, and the goal of men walking on the Moon seemed almost laughably insurmountable.

Dr. Yeomans said the spacecraft approached the asteroid at only 22 miles per hour before breaking rockets placed the craft into a 280-by-200-mile orbit, where it travels at only 2 m.p.h., the speed of a walking man.
Even then, they arrive back on Earth, after six months in orbit, struggling to walk.
In March 1969, Apollo 9 practiced docking with the lunar landing vehicle in Earth orbit; two months later Apollo 10 did the same in moon orbit; and on July 20 , 1969 40 years agoo — Apollo 11's Neil Armstrong and Buzz Aldrin walked on the moon at Tranquillity Base while Michael Collins orbited above in the mother ship that would ferry them back home.
"Before John Glenn orbited the earth, or Neil Armstrong walked on the moon, a group of dedicated female mathematicians known as 'human computers' used pencils, slide rules and adding machines to calculate the numbers that would launch rockets, and astronauts, into space.
Engineers dared astronauts to walk in space and dock two spacecraft in orbit; astronauts met the challenge with resolve and an acceptance of the inherent risks.
Orbit is also really cool – after locking on Hover will stay about 10 feet away from you and orbit around you (even while you walk) the result is a cool video straight out of an action movie.
In total, about 487 people have visited outer space and reached orbit, and, of these, twelve have walked on the Moon.
