pairs,answer the,questions.,Lesson 1,What caused the explosion,a,1.What accident does the photograph show?,2.When and where did this incident take place?,3.What caused the accident?,4.How many lives were lost in the accident?,第4页,Skim through the text quickly to check your answers.,b,NASA space shuttle consists of three major components:a winged,orbiter that carries both crew and cargo,an external tank containing,liquid hydrogen(fuel)and liquid oxygen(oxidizer)for the orbiters three main rocket engines,and a pair of large solid-propellant rocket boosters(SRBs).,On January 28,1986,the,Challenger,shuttle and its crew of seven(including teacher Christa McAuliffe,who had been selected to be the first private citizen in space)were destroyed shortly after launch from Cape Canaveral,Florida.The primary cause of the loss of the,Challenger,was the failure of an O-ring seal of a joint on one of the solid rocket,boosters.,The SRBs are constructed in four cylindrical sections.These have to be sealed together completely to prevent the escape of the extremely hot,by-products of the burning fuel during a launch.The O-rings are rubber rings that play a vital part in sealing the joints.,A,第5页,On the day of the launch,the weather was unusually cold and this caused the rubber of one of the O-rings on the joint between the bottom two segments of the right SRB to become brittle.This,combined with the faulty design of the joint,allowed hot gases from the burning solid rocket fuel to escape.The gases and flames burned through the metal that held the SRB in position.When the SRB broke off,it ruptured the side of the external fuel tank.This allowed the liquid hydrogen and oxygen to mix prematurely and this is what caused the explosion.,第6页,Read the first paragraph of the text and,in the diagram,label the three main components of the space shuttle.,c,History capsule,Another tragic accident occurred on February 1,when,the Columbia space shuttle broke up over north-central Texas at an,altitude of about 40 miles(60 kilometers)as it was returning from an,orbital mission.All seven crew members died in the accident.,a._,b._,c._,_,第7页,Read through the text

failure,electrical failure,materials failure,human error,etc.),how,the accident could have been avoided,and what happened,as a consequence of the accident.,j,第12页,Interviewer:,What happened in the immediate aftermath of the,Challenger,accident?,Spokesperson:,In early February 1986,President Ronald Reagan,announced the creation of a Presidential Commission on the,Space Shuttle,Challenger,Accident.,Interviewer:,Known to most people as the Rogers Commission,right?,Spokesperson:,Thats right.The chairman of the commission was,William P.Rogers.At the same time,NASA established the,Challenger,Data and Design Analysis Task Force to support the,work of the Commission.,Interviewer:,How long did the investigation take?,Spokesperson:,It took four months to complete and required the,involvement of more than 6,000 people.The report was,published and delivered to the president early June 1986.,第13页,Interviewer:,So what changes were made as a result of the,commissions report?,Spokesman:,Well,modifications were made both to shuttle,hardware and to NASAs safety and quality assurance,procedures.While the space shuttle fleet was grounded,hundreds of modifications were incorporated into the shuttle,system.The SRBs were completely redesigned and a new joint,design was subjected to stringent examination and review.,NASA put the main space shuttle engines through the most,thorough ground-testing program in their history.This was the,equivalent in operational time to more than 36 real missions.All,engine improvements were certified to demonstrate improved,reliability and operating safety margins.,Interviewer:,I see.,Spokesman:,And,as I mentioned,apart from making changes to,hardware,NASA completely reorganized its safety programs.The,Office of Safety,Reliability,Maintainability,and Quality,Assurance was established in 1986.This has direct authority for,safety and quality control for all NASA operations.,第14页,Lesson
