Space Rocket History #29 – Mercury-Atlas 5 With Enos

Posted on September 12, 2013 by spac9750

Following the successful suborbital missions of Allan Shepard and Gus Grissom, NASA believed the Mercury capsule was ready for an orbital mission. But, there was a problem, the Redstone booster did not have the power to place the Mercury capsule into orbit. The Atlas booster had the power to put the capsule in orbit but not the confidence of NASA. By September of 1961 Four launches of the mercury-atlas had been made with only a 50 percent success rate…

Mercury-Redstone 4 was the fourth mission in the Mercury-Redstone series and the second U.S. manned suborbital spaceflight. The mission was essentially a repeat of Alan Shepard’s Freedom 7 flight. So why was it necessary to launch another sub-orbital mission? Why not proceed with an orbital flight to match the Soviet Vostok 1? Among other things the U.S. needed more space experience to corroborate the “Man-in-Space” concept. Also the Redstone was the only booster NASA had that was approved for manned launches. The Atlas booster was available but not ready. Atlas was capable of putting a Mercury Capsule into orbit, but it had been launched three times with unmanned capsules, and it had exploded on 2 of the 3 attempts.

Over 52 years ago, in the early hours of May 5th, 1961 the US prepared to launch its first man into space. Three weeks earlier, the Soviet Union had sent Yuri Gagarin on an orbital mission. This was a suborbital mission planed to last only 15 minutes. For the moment that did not matter, the entire nation held its breath while Alan Shepard became America’s first man in space.

“Dear friends, you who are close to me, and you whom I do not know, fellow Russians, and people of all countries and all continents: in a few minutes a powerful space vehicle will carry me into the distant realm of space. What can I tell you in these last minutes before the launch? My whole life appears to me as one beautiful moment. All that I previously lived through and did, was lived through and done for the sake of this moment.” Yuri Gagarin prior to launch of Vostok 1.
