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 Earths 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

they go out of their space shuttle to take a _.In outer space astronauts cannot take off their _,which protect them and provide oxygen.In 1965,Alexei,Leonov,from the former Soviet Union became the first human being to take a walk in space.,astronaut,space,space exploration,space shuttle,rockets,launched,space station,spacewalk,spacesuits,Consolidation,The ancient Greeks called them“,planetes,.”(PLAN-,ee,teess,).The word means wanderer-one who moves from place to place with no home.,On a dark,clear night,away from the lights of a city,you can still find the five wanderers using only your eyes.However they are no longer mysteries.Today we know them as Saturn,Jupiter,Venus,Mercury and the closest planet to Earth,the red planet,Mars.,Extension,outer,Nine

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
