32、Level S56The Race to SpacePeople began racing into space in the 1950s and 1960s.The first person in space was cosmonaut Yuri Gagarin,from Russia(then part of the Soviet Union).He orbited Earth one time and landed safely after 108 minutes on April 12,1961.In 1968,U.S.astronauts on Apollo 8 successful
33、ly orbited the Moon.On July 20,1969,the crew of Apollo 11 stepped onto the Moons surface.Space programs created vehicles that let people stay in space for days or weeks.However,scientists were building a structure in which people could actually live for months or years.Space StationsThe Soviet Union
34、 launched the first space station in 1971.It spent 175 days in space.In 1973,the United States launched Skylab.It supported three missions before being abandoned in 1974.The Soviet Union launched the Mir(MEER)space station in 1986.It was the first space station that lasted more than a few years.Mir
35、remained in orbit for fifteen yearsthree times longer than planned.Scientists from many different countries visited it.The Soyuz spacecraft,first created in the 1960s,are still being used to take people to and from the International Space Station.438 Days in SpaceA Russian scientist spent 438 days i

43、tronaut Karen Nyberg shows how she washes her hair on the ISS.The tube hanging on the wall is for liquid waste.The base on the floor is for solid waste.The ISS has two toilets.Life in Space Level S910SleepingThe ISS has six small“sleep pods”that each hold a sleeping bag with armholes.Each bag is tie
44、d to the wall to keep the astronaut from floating away.Because of the space stations orbit,astronauts on board see sixteen sunrises and sunsets every day.Since people are used to sleeping at night and being awake during the day,this can cause sleep problems.The space station has a“shades down”period
45、.During this time,it is dark and quiet to allow the astronauts to get the sleep they need.EatingAstronauts eat many of the foods most people enjoy,such as chicken,fruits,peanut butter,and brownies.The ISS has no refrigerator,so all food has to be packed so it wont spoil.The station does have an oven
46、,however.Some food can be eaten as is.Other food,such as spaghetti,must have water added.Astronauts use liquid salt and pepper.Regular salt and pepper would float away and damage the space station equipment.Once the food is prepared,however,astronauts still have to get used to swallowing.Astronaut P
47、iers Sellers said it was like“eating while lying on one side.”An astronaut has a breakfast of eggs and sausage on a tortilla with coffee on the ISS.Astronaut Alvin Drew prepares to sleep on the ISS.Life in Space Level S78Before Mir was abandoned,work began on a new,larger space station.The United St
48、ates,Russia,Japan,Canada,and other countries worked together.In 1998,the first section of the International Space Station(ISS)was launched into orbit.More sections have been added over the years,and more are planned for the future.As of 2012,the ISS was as long as a football field and weighed almost
49、 1 million pounds(453,592.3 kg).An Astronauts LifeAstronauts go to school for many years before they begin training.The physical training involves being weightless while flying in an airplane.Astronauts also spend up to seven hours in a space suit while working underwater.They work on models of spac
50、e vehicles in a huge pool.Sick in SpaceThe change to being weightless can make some people ill.Fortunately,the ISS comes with special bags.They have a cloth side that can be used to clean up as well as an extra sealable bag attached for easy disposal.Over the years,more than two hundred people from
