On May 5, 1961, Shepard piloted the Mercury-Redstone 3 mission and became the second person, and the first American, to travel into space. He named his spacecraft, Mercury Spacecraft 7, "Freedom 7". He awoke at 01:10, and had breakfast consisting of orange juice, a filet mignon wrapped in bacon, and scrambled eggs with his backup, John Glenn, and flight surgeon William K. Douglas. He was helped into his space suit by suit technician Joseph W. Schmitt, and boarded the transfer van at 03:55. He ascended the gantry at 05:15, and entered the spacecraft five minutes later. It was expected that lift off would occur in another two hours and five minutes, so Shepard's suit did not have any provision for elimination of bodily wastes, but after being strapped into the capsule's seat, launch delays kept him in that suit for over four hours. Shepard's endurance gave out before launch, and he was forced to empty his bladder into the suit. Medical sensors attached to it to track the astronaut's condition in flight were turned off to avoid shorting them out. The urine pooled in the small of his back, where it was absorbed by his undergarment. After Shepard's flight, the space suit was modified, and by the time of Gus Grissom's Mercury-Redstone 4 suborbital flight in July, a liquid waste collection feature had been built into the suit.
