I dont kno da freekin answer
Alan B. Shepard JR
I'm not sure what you are referring to. Mercury-Redstone 1 and Mercury-Redstone 1A were test flights for the Mercury program that eventually took the first Americans into space. Mercury-Redstone 1 failed during launch. Mercury-Redstone 1A was a sub-orbital (ballistic) test flight. Neither was manned.
Redstone.
The first flights were either unmanned or had a chimp-o-naut aboard. Mercury-Redstone 3 launched on May 5, 1961 with Alan Shepard aboard.
Alan Shepard took part in two spaceflights. First was Mercury-Redstone 3, and the second was Apollo 14.
For the US, it was Mercury-Redstone 3 (piloted by Alan Shepard). For the USSR it was Vostok 1 (piloted by Yuri Gagarin)
Freedom 7 (or Mercury Redstone 3) had only one person on board. Alan Bartlett Shepard, Jr.
Here are the most well known Redstone Mercury-Redstone Gemini Saturn V (Apollo missions) Space Shuttle.
Grissom only. I find that very strange though.
For the US, it was Mercury-Redstone 3 (piloted by Alan Shepard). For the USSR it was Vostok 1 (piloted by Yuri Gagarin)
It was launched at Cape Canaveral, Florida, on May 5, 1961 (9:34 EST). The Freedom 7 capsule was used by Alan Shepard on the first US manned space mission, a 15-minute suborbital flight called Mercury Redstone 3. The rocket used variants of the Redstone and Jupiter-C ICBM boosters (for later Mercury missions, the Atlas missile was used).
"Mercury Redstone 3", a Mercury capsule atop a Redstone rocket booster, carried NASA astronaut Alan Shepard on a 15-minute suborbital flight, May 5, 1961. The spacecraft was nicknamed "Freedom 7" and Shepard was the first American in space. Six months earlier, the more powerful Atlas rocket of "Mercury Atlas 5" had lofted Enos the chimpanzee for two orbits of the Earth. After Virgil "Gus" Grissom made a Redstone flight similar to Shepard's, John Glenn flew "Mercury-Atlas 6" and his capsule "Friendship 7" on February 20, 1962, becoming the first American to orbit the Earth.
