42、present your opinion and try to persuadeothers to believe in your imagination.7ZvFni5aCeBasic atmospheric dataThe Martian atmosphere is composed mainly of carbon dioxide(CO2>.It is very thin (less than 1 percent of the Earths atmosphericpressure>.Evidence suggests that the atmosphere was much

43、denser in theremote past and that water was once much more abundant at thesurface.Only small amounts of water are found in the lower atmospheretoday, occasionally forming thin ice clouds at high altitudes and, inseveral localities, morning ice fogs.Nitrogen, oxygen, carbon monoxide,11/17and the rare

44、 gases (neon, argon, krypton, and xenon> also are present insmall quantities.7ZvFni5aCeThe characteristic temperature in the lower atmosphere is about 200K,whichisgenerally colder than the average daytime surfacetemperature (250 K>.It decreases upward from the surface at about 1.5 Kper vertica

45、l kilometer.7ZvFni5aCeUnlikethat of the Earth, the total mass (and pressure> of theatmosphereexperiences largeseasonal variations,ascarbondioxide“snows out”at the winterpole.The annual variation ofsurfacepressure was measured to be about 26 percent of the mean atmosphericpressure (7-8 millibars&g

46、t; at the lander sites, equivalent to some 7.9 1012×metric tons of carbon dioxide.Although the Martian atmosphere is thin,itsupports avariety of clouds.White clouds are waterice, whilethe“yellow ”ones are dust storms that throw dust into the atmosphere toheights of 10 km (6 miles> or more.Ev

47、en in the absence of storms, theatmosphere isnever clear ofdust, which greatly affects atmosphericstructure.7ZvFni5aCeReference for TeachingExploring the planet MarsPeople on Earth have always been interested in the planet Mars.Recently, that interest has increased because several successful spacecr

48、aft have been placed in orbit around Mars.These include the12/17American space agencys Mars Global Surveyor and Mars Odyssey andthe European Space Agencys Mars Express7ZvFni5aCe.Perhaps the most exciting event took place on January third.That is when the first of two Mars exploration vehicles succes

49、sfully landed onthe Red Planet.The first lander is named“Spirit ”.It came to rest in an area of Mars named Gusev Crater.Millions of people used their computers to link with NASAs Internet Web site to see photographs sent back bySpirit. 7ZvFni5aCeOn January fifteenth, NASA scientists told Spirit to u

50、se its six wheels to move off the landing device.It did this successfully and rolled on to the surface of Mars.Excited NASA officials said Spirit was now ready to begin its task of exploring the surface of the Red Planet7ZvFni5aCe.On January twentieth, scientists told the exploration rover to use on

51、e of its tools to study the soil near the rock.The next day, Spirit began having problems.It answered radio signals, but it would not send back13/17scientific information.7ZvFni5aCeNASA officials began to work to correct the problem with Spirit s computer.The part of the computer that stores informa

52、tion was notworking correctly.On February 1st, NASA announced that Spirit s computer memory had been successfully repaired.It will begin scientific examinations of rocks later this week7ZvFni5aCe.The second vehicle is named“Opportunity”.It landed in an area of Mars called Meridiani Planum.NASA scien

53、tists say Opportunity landed inside a large hole in the surface of the planet.Photographs from Opportunity show several large formations of rock.The photographs clearly show this rock is below the surface.NASA scientists say the rock they see in the photographs is not like anything they have ever se

54、en before. 7ZvFni5aCeNASA officials say they have discovered and confirmed that Opportunity landed on an area of Mars that is rich in t he mineral crystalline hematite.On Earth such hematite usually forms in the presence of water.Scientists want to know if the hematite on Mars was formed under water

55、 too. 7ZvFni5aCeSome evidence suggests that long ago the Meridiani Planum area of Mars was wet and held water.Opportunity will search for more evidence of water and any evidence that some kind of life could have existed in the area.7ZvFni5aCe14/17When they get to an interesting area they reach out with a
