Sputnik 1
On Oct. 4, 1957, Sputnik 1 successfully launched and entered Earth's orbit. The successful launch shocked the world, giving the former Soviet Union the distinction of putting the first human-made object into space.'Sputnik' originally meant 'fellow traveler,' but the modern word for the Russian’s is ‘satellite’. -
Explorer 1
Explorer 1 became the first successfully launched satellite by the United States when it was sent to space on January 31, 1958. The Soviet Union's launch of Sputnik 1, Explorer 1's success marked the beginning of the U.S. Space Age.
The satellite,helped detect radiation belts around the earth that held it in place by the planet’s magnetic field. -
Ham the Astrochimp
It’s not always well remembered that two chimpanzees helped paved the way for human spaceflight with tests in the 1960. In the 1940s and 1950s, monkeys perished for the U.S. cause and dogs died in Soviet spaceflight testings.
The space chimps, Ham and Enos, were celebrated at the time. Ham, the first chimp in space .Later, Enos flew before before John Glenn orbited the Earth. -
Yuri Gagarin
The United States and the Soviet Union vigorously competed to push the boundaries of mankind's exploration of space. The Russians launched a small craft carrying cosmonaut Yuri Gagarin to new heights. His 108-minute flight gave him a permanent place in the history books as the first man in space. -
Alan Shepard
Alan Shepard became the first American in space when the Freedom 7 spacecraft blasted off from Florida on May 5, 1961. Ten years later, Shepard would leave Earth's atmosphere again to become the fifth man to walk on the moon.
Shepard served in the Navy in various capacities. He received a civilian pilot's license while in naval flight training, and spent several tours on aircraft carriers in the Mediterranean. He attended the U.S. Navy Test Pilot School in 1950. -
Apollo 11
The primary objective of Apollo 11 was to complete a national goal set by President John F. Kennedy on May 25, 1961: perform a crewed lunar landing and return to Earth. -
John Glenn
Glenn, who served four terms as a U.S. senator from Ohio, was one of NASA's original seven Mercury astronauts. His flight on Friendship 7 on Feb. 20, 1962, showed the world that America was a serious contender in the space race with the Soviet Union.Oct. 29, 1998, when he was 77, made him the oldest human to venture into space. On Discovery he participated in a series of tests on the aging process. The aging population was one focus of his work as a U.S. senator. -
2 Spacecraft rendezvous in space
Though engaged in the study of space rendezvous for more than 20 years, Mr. Dennehy was struck by the enormity of the task that lay before those early astronauts and engineers.
They were excited about breaking new technical ground.A fresh look at this first proximity flight in low Earth orbit inspired Mr. Dennehy, bringing a renewed vigor to his current work on rendezvous and capture capabilities.the plans that are underway for a rendezvous mission with an asteroid. -
Apollo 1
One of the worst tragedies in the history of spaceflight occurred on January 27, 1967 when the crew of Gus Grissom, Ed White, and Roger Chaffee were killed in a fire in the Apollo Command Module during a preflight test at Cape Canaveral. They were training for the first crewed Apollo flight, an Earth orbiting mission scheduled to be launched on 21 February. -

Lunokhod 1
An amazing spacecraft gently settled to the lunar surface on 17 November 1970. It carried the first successful robotic lunar rover -- Lunokhod 1. It was operators in the Soviet Union. in six years of operation the Mars Exploration Rover Opportunity has traveled about 12 km. The rover was driven by solar power during the day; at night it parked and relied on thermal energy from a polonium-210 radioisotope heater to survive the cold (-150°C). -
Spacewalk
Spacewalk is an open-source systems management solution for system provisioning, patching and configuration licensed under GNU General Public License v2. A spacewalk is also called an EVA. EVA stands for extravehicular activity.The first person to go on a spacewalk was Alexei Leonov. He was from Russia.
