Read the passage and answer the question below Spacewalkers on the space shuttle Atlantis got to travel to outer space to help build the space station, and install some of the latest technology on their 2006 mission to the International Space Station. The 2006 Atlantis mission to the space station marked the return to construction of the space station after a delay of several years. The delay had been called after the space shuttle Columbia disaster in 2003. In the years since 2003, Atlantis had been carefully checked and upgraded. Its return to space in 2006 revived hopes and plans for improvements to the space station. The crew of Atlantis included Joe Tanner, Heidemarie Stefanyshyn-Piper, Dan Burbank, and Steve MacLean. These astronauts had to receive extensive training before their flight because their spacewalks would be unusually complicated. Once at the space station, they would perform three separate spacewalks in teams of two astronauts. The purpose of the spacewalks was to attach a large truss structure holding solar panels to the space station. On Earth, the truss assembly weighed seventeen tons and made up a forty-five foot long package. On September 9, the astronauts were ready. Atlantis was ready, too, and after a delay of several days, the weather was right for a launch. At 11:15 A.M., Atlantis with its crew of astronauts blasted off for a twelve-day trip. 1.What was the purpose of this space travel? 2.How many spacewalkers were there on the shuttle? 3.What was provided to the spacewalker before mission? 4.What was supposed to be installed to the space station? 5.How long did the trip last?
