Each of the Mercury missions had a name followed by the number 7. Alan Shepard flew Freedom 7, Gus Grissom in Liberty Bell 7, John Glenn aboard Friendship 7 (pictured), Scott Carpenter in Aurora 7, Wally Schirra flew Sigma 7, and Gordon Cooper aboard Faith 7. Deke Slayton never flew because of a heart condition, but had he flown his mission would have been Delta 7.
So, what’s with all the ‘7’s? Continue reading “Vintage Space Fun Fact: The Mercury ‘7’s”
I’ve talked in previous posts about the first manned Soviet space program, Vostok, and Yuri Gagarin’s historic Vostok 1 flight. One aspect neither of these posts touched on, however, was the reaction in the United States. Understandably, Americans were less jubilant about Gagarin’s flight than the Soviets. But the feelings of defeat, frustration, and in some cases fear soon disappeared when on May 5, 1961, Alan Shepard became the first American in space.
In the grand scheme of the space race, the first man in space almost pales in comparison to the feat of placing a man on the moon. But the race for manned flight was extremely important in the early 1960s. Shepard’s Freedom 7 flight was, like Gagarin’s Vostok 1 mission, the climax of years of preparation and training, and it set in motion a chain of events that set the course of the space race. The flight was a fifteen-minute suborbital hop, officially classified as a pre-orbital training flight, but Americans didn’t care. An American had been in space. (Pictured, Shepard in Freedom 7 the morning of launch. May 5, 1961.) Continue reading “Shepard: First American in (Suborbital) Space”
I’ve been posting a lot about landing methods – NASA’s use of splashdowns, why the method was not a long-term solution to the problem of returning from space, and a comparison to Soviet methods. The former, splashdowns, have been a focus of a number of posts. I have previously focussed on the complexity of splashdowns and the significant resources involved as driving force behind NASA’s pursuit of land landing methods with its second-generation manned spaceflight program. But this only tells half the story. A look at the numbers of men and ships involved offers a different illustration of the reasons to pursue a land landing method. (Pictured: The crew of the USS Champlain cheer on Alan Shepard following his Freedom 7 splashdown, 1961.) Continue reading “Sailors, Ships, and Splashdowns”
The experimental, creative, and at times imaginative nature of the Mercury program has always fascinated me. The program and the decision that preceded it answer a totally unique question: what do you do when you suddenly need to put a man in space and you have no previous experience to build off of?
