  • First American to Orbit the Earth

    First American to Orbit the Earth
    John Glenn, in the craft Friendship 7 is the first american to orbit Earth, and is the fifth person in space. The difference between orbiting the Earth, and just making it to space is that when you orbit Earth, you are still falling, but you have enough horizontal velocity to not get closer to Earth as you fall. This velocity required is about 29.78 kilometers per second for Earth, which is very fast. Dunbar, Brian. "Glenn Orbits the Earth." NASA. NASA, 17 February 2012. Web. 11 December 2013.

  • First Spacewalk

    First Spacewalk
    A russian cosmonaut, Alexei Leonov, in the craft Vokshod 2 became the first man to exit the craft in which he was brought to space with. When it was time to get back in the capsule, his suit had expanded, so without telling anyone on the ground so noone woud panic, he bled some oxygen out of a valve in his suit, and eventually he made it in the airlock where his crewmate equalized the preassure, and he made it back safely.

    First American Spacewalk
    Ed White, in the craft Gemini 4 is the first american to preform a spacewalk. He used an oxygen jet gun to propell himself in space, and opened the hatch to outer space on his third orbit. After the first 3 minutes, the oxygen ran out in the jet gun, so he hat to pull himself back to the craft by pulling on the tether which kept him from drifting away from the capsule. Dunbar, Brian.

  • First Manned Craft to Orbit the Moon

    First Manned Craft to Orbit the Moon
    Commander Frank Borman, Command Module Pilot James Lovell, and Lunar Modlule Pilot William Anders, in the Saturn V rocket on the american mission Apollo 8 were the first men to orbit the moon. The three men in the command module were the first people to ever see the other side of the moon. Dunbar, Brian. "Apollo 8." NASA. NASA, 8 July 2009. Web. 12 December 2013.

  • First Man on the Moon

    Niel Armstrong, Edwin E. Aldrin Jr., and Michael Collins, in the Saturn V rocket, on the american mission Apollo 11 went to the Moon. Niel Armstrong, and Edwin E. Aldrin Jr. walked on the moon's surface while Michael Collins was in orbit above the moon's surface. Niel Armstring was the first man on the moon. This mission was conducted because of our goal to have a manned landing on the moon. Dunbar, Brian. "Apollo 11." NASA. NASA, 8 July 2009. Web. 12 December 2013.

  • Last Man on Moon to date

    Last Man on Moon to date
    Eugene Cernan, Ronald B. Evans, and Harrison H, Schmitt in the Saturn V rocket on the american mission Apollo 17 are the last men to go to the moon to date. The lunar rover traveled a total of 30.5 kilometers. 110.4 kilograms of lunar material was collected, and they stayed on the lunar surface for 75 hours, and were in orbit for 17 hours. "Apollo 17."

  • First Untethered Sapcewalk

    First Untethered Sapcewalk
    Bruce McCandless, an american in the Challenger Space Shuttle preformed the first untethered spacewalk, followed by Robert Stewart. They both used nitrogen propelled jet packs called MMUs for Manned Maneuvering Units. Dunbar, Brian. "First Untethered Spacewalk." NASA. NASA, 15 March 2010. Web. 12 December 2013.

  • First Module of the ISS

    First Module of the ISS
    The first module of the ISS was launched into orbit on November 20, 1998. The russian module is called Zarya. It orbits at about 400 kilometers high, and is 19,300 kilograms, and is 12.55 meters long. It's cost is estimated between 35 and 100 billion dollars. "Zarya." Zarya. n.d. Web. 12 December 2013.
