Part 1 Warming up A 1.An American spacecraft is traveling to Mars to collect information about the red planet.The Mars Reconnaissance Orbiter left Cape Canaveral in Florida on August 12th.The space vehicle is expected to arrive in March of next year.It is to orbit the planet for at least four years. 2.The U.S.space shuttle Columbia has returned to Earth after an abbreviated stay in space because of a mechanical problem.The Space Agency ordered the shuttle back to Earth after one of the three power generators failed Sunday.The generators called "fuel cells"provide all of shuttle's electrical power,and NASA safety rules require the space ship to return to Earth if any fuel cell fails. 3.US space shuttle Discovery has made a successful lift-off from Kennedy Space Center in Florida,en route to the International Space Station.The shuttle with 5 male and 2 female astronauts onboard will take another section of the half-built International Space Station a little truss,or frame into orbits.It's scheduled to come back to earth on December 21

Part 1 Warming up B Mir means "peace"in Russian.The station had a core block of living quarters and six docking ports for supply ships. Mir was built by the Soviet Union,which is now Russia.It cost $4.2 billion to build and maintain it.Scientists spent ten years building it,from 1986 to 1996.it weighs 135 tons and has a volume of 9900 cubic feet.It is 63 feet wide and 85 feet long. Mir hosted 104 cosmonauts,astronauts,and visitors.Forty-six flights were made to Mir.Cosmonaut Valery Polyakov holds the record for the longest stay in orbit,which is 438 days.And cosmonaut Sergei Avdeyev totaled 747 days between his three separate missions to Mir,which is the longest total for any human staying in space. The Mir Space station has been sailing through space for 15 years.But Mir doesn't work very well any longer,and its orbit is failing.It has been replaced by the new International Space Station,where the U.S.A.,Russia and many other countries work together.So Russia is going to bring Mir down into the ocean.They will be careful that none of Mir's pieces hit places where people live

Part 1 Warming up B This event will be big news-as it should be!Since the Russians began building Mir in 1986,it has survived a fire, collisions with other spacecraft,and even attacks on its wiring by microbes that ate metal and glass!We have learned a lot from Mir about how to live and work in space. The Russian Space Agency guided Mir back to Earth on March 23rd.Fragments of the huge spacecraft splashed down in the South Pacific Ocean just as ground controllers had planned.It was a flawless re-entry.No one was hurt. Mir was truly a remarkable achievement of human ingenuity, breaking uncounted records for human spaceflight.The Mir is gone but will never be forgotten
