The Shenzhou-VI spacecraft has been sent into orbit in the second half of this year. It carried two astronauts and stayed in space for several days. The two astronauts on the mission conducted scientific experiments in the orbit capsule of the spacecraft during the space flight, but there were no plans for space walks or other activities outside the spacecraft. the process of space explorationThe first artificial satellite was launched.People could orbit the Earth in 1961.Photos are taken and samples are collected from the planet.Earth, of course, can be studied without the aid of spacecraft. Nevertheless it was not until the twentieth century that we had maps of the entire planet. Pictures of the planet taken from space are of considerable importance;orbit: 149,600,000 km from Sun
diameter(直径): 12,756.3 km mass(质量): 5.972e24 kg Earth is the third planet from the Sun and the fifth largest: Placing a satellite into orbit requires a large amount of energy, which must come from the launch vehicle, or device that launches the satellite. The satellite needs to reach an altitude of at least 200 km (120 mi) and a speed of over 29,000 km/h (18,000 mph) to lift into orbit successfully. Satellites receive this combination of potential(势能) energy (altitude) and kinetic(动能) energy (speed) from multistage rockets burning chemical fuels.Apollo Eleven Countdown A rocket launch countdown. A common sound in the nineteen-sixties. But this was not just another launch. It was the beginning of an historic event. It was the countdown for Apollo Eleven -- the space flight that would carry men to the first landing on the moon. Two-and-one-half minutes after the Apollo Eleven launch, the first-stage rocket separated from the spacecraft. Twelve minutes later, the spacecraft reached orbit. Its speed was twenty-nine-thousand kilometers an hour. Its orbit was one-hundred-sixty-five kilometers above the Earth.
This was the time for the crew to test all the spacecraft systems. Everything worked perfectly. So, the NASA flight director told them they were "go" for the moon. They fired the third-stage rocket. It increased the speed of the spacecraft to forty-thousand kilometers an hour. This was fast enough to escape the pull of the Earth's gravity.
Apollo Eleven was on its way to the moon. In seventy-seven hours, if all went well, Apollo Eleven would be there. On July 20, 1969, American astronaut Edwin "Buzz" Aldrin, Jr. (pictured) became the second person to walk on the moon. Aldrin stepped onto the moon shortly after fellow Apollo 11 astronaut, Neil Armstrong. While millions of people on earth watched a televised broadcast of the event, Armstrong and Aldrin spent two hours exploring the lunar surface, gathering samples, taking photos, and setting up experiments. I want to collect some samples from the moon .One of a number of things , or part of a whole thing, which can be looked at to see what the rest is like.spaceship/spacecraftspace shuttle space station spacespacesuitspacewalk astronaut (spaceman/spacewoman)space explorationA.
