Receiving a patent usually alerts a serious milestone. As an unique proper granted for an invention, be it a product or a course of, it normally denotes a brand new approach of doing one thing, thereby turning into essential. In the case of the Mercury space capsule, nonetheless, the patent got here nearer to the finish.
Project Mercury was conceived as a NASA programme to place the first American astronauts in space. Named after a Roman god who was very quick, the undertaking notched up many successes. At the centre of this success was the Mercury space capsule.
“Space capsule”
The principal designer of the Mercury spacecraft was Maxime Faget, a mechanical engineer who additionally contributed to the designs of the Gemini and Apollo spacecraft. Faget, together with Andre Meyer, Robert Chilton, Willard Blanchard Jr., Alan Kehlet, Jerome Hammack and Caldwell Johnson filed for a patent titled “Space capsule” on October 16, 1959.
In this patent software, they described their invention regarding space autos as a “manned capsule configuration capable of being launched into orbital flight and returned to the Earth’s surface.” Additionally, it was able to offering “protection for its occupant from the deleterious effects of large pressure differentials, high temperatures, micrometeorite collisions, high level acoustical noise, and severe inertial and impact loads.”
Not cosy
It did all that, however the capsule was a reasonably small one, with room for only one astronaut. What’s extra, this astronaut needed to keep seated all through the flight. While there was little or no room for even the single seated astronaut to make any actions, it was argued that not a lot was required as the pilot would solely want to maneuver his arms and head, and was to by no means depart the spacecraft throughout flight.
Following uncrewed flights and people with primates as a part of Project Mercury, the first crewed flight passed off on May 5, 1961. Alan Shepard made the first crewed Mercury flight in a capsule that he named Freedom 7. The 15-minute flight that went into space and got here again down made him the first American in space.

Between 1961 and 1963, there have been six profitable flights as a part of Project Mercury that confirmed that Americans may fly in space. While two of those flights have been suborbital flights ( reached space and got here proper again down), the different 4 made it into orbit and circled our Earth.
Every time the Mercury spacecraft re-entered the Earth’s ambiance, the blunt finish got here in first to not solely decelerate the spacecraft, but additionally shed the warmth brought on by friction with the air throughout the descent. With layers of warmth resistant ablative resins coating the curved warmth defend, it charred away to minimise structural heating, stopping harm to the spacecraft, and naturally, defending the crewman.
The final of the six profitable crewed Mercury Project spaceflight passed off on May 15, 1963. Each of those flights lasted from quarter-hour to 34 hours, with most lasting lower than 9 hours.
Just a formality
This meant that by the time the patent for the Mercury capsule was awarded on June 11, 1963, it had already been put to make use of a number of instances efficiently, with every of the successes celebrated by a complete nation. The patent, which was assigned to NASA, was merely a formality.
In reality, NASA retired the Mercury capsule in the identical week during which the patent was awarded. The first manned space automobile of the U.S. was retired with honours after all, having been central to a undertaking that got here at the peak of the space race between the U.S. and the Soviet Union.
