amstrong
Armstrong, Neil Alden a United States astronaut, was the first person to set foot on the moon. On July 20, 1969, Armstrong and Buzz Aldrin landed the Apollo 11 lunar module Eagle on the moon. Armstrong left the module and explored the lunar surface. Upon taking his first step onto the moon, he said: "That's one small step for a man, one giant leap for mankind." But the word a was lost in radio transmission. -
early astronauts
Even more stringent physical and psychological examinations followed, and in April 1959 NASA announced its selection of seven men as the first American astronauts. They were Navy Lieutenant M. Scott Carpenter; Air Force Captains L. Gordon Cooper, Jr., Virgil I. "Gus" Grissom, and Donald K. "Deke" Slayton; Marine Lieutenant Colonel John H. Glenn, Jr., and Navy Lieutenant Commanders Walter M. Schirra, Jr., and Alan B. Shepard, J -
Challenger disaster
Challenger disaster was one of the worst accidents in the history of human space flight. On Jan. 28, 1986, the space shuttle Challenger broke apart 73 seconds after launch. The accident happened at an altitude of 26,000 feet (14,020 meters) and at about twice the speed of sound. Momentum carried the debris to an altitude of 65,000 feet (20,000 meters) before it fell back to Earth. The crew quickly lost consciousness from air loss after the breakup. They died about three minutes later, when the c -
Stardust
Stardust was a United States space probe designed to collect material from a comet and return it to Earth for study. Scientists believe that comets preserve leftover ice, rock, and dust from the solar system’s formation. By analyzing samples gathered by Stardust, they hope to learn more about the solar system’s composition and history. The National Aeronautics and Space Administration (NASA) launched Stardust on Feb. 7, 1999. -
mars exploration
Mars Exploration Rover Mission consists of two robotic rovers sent to Mars. The rovers are nicknamed Spirit and Opportunity. They were had to go study the history of water on the planet. Engineers and scientists at the Jet Propulsion Laboratory designed and built the rovers for the United States National Aeronautics and Space Administration (NASA).NASA launched Spirit on June 10, 2003. Opportunity followed on July 7. Spirit landed on Jan. 4, 2004, in Gusev Crater. -
spacecraft
Phoenix [spacecraft] is a spacecraft sent to Mars to study the history of water on the planet. The Phoenix mission was also designed to investigate if you could survive on the Martian arctic region. The United States National Space Administration (NASA) launched Phoenix on Aug. 4, 2007. Phoenix operated from May to November 2008. The craft’s landing site lies at about 68° north latitude about as far north on Mars as northern Alaska is on Earth. -
dawn
Dawn is a space probe designed to study two of the largest asteroids, Ceres and Vesta. These two bodies formed early in the history of the solar system and have remained ever since then. By analyzing data gathered by Dawn, scientists hope to learn more about the early solar system. Ceres and Vesta orbit the sun between the orbits of Mars and Jupiter in a region known as the Main Belt. NASA launched Dawn in September 2007.
