    NASA has【C1】________details about a test flight for Orion, a spacecraft the organization built "to take humans farther than they’ve ever gone before." On December 4, Orion will【C2】________from Cape Canaveral, Florida for a two-orbit, four-hour, 3,600-mile flight meant to test the craft for safety systems, particularly high-speed re-entry systems, as the craft will return to Earth traveling at 20,000 miles per hour at a temperature over 4,000 degrees Fahrenheit. Nobody will be on board for the test.
    The flight has been dubbed "Exploration Flight Test-1" and will mark the farthest distance from the Earth that a spacecraft【C3】________to carry a crew has traveled in over 40 years, NASA said. By【C4】________, the International Space Station is only about 240 miles up from the ground. It will cost $375 million.
    For future flights, Orion will lift off using an【C5】________new heavy-lift rocket system, Space Launch System (SLS), which was designed to send humans into deep space. The first SLS test is set for 2018 and will include an orbit around the moon, which may become a manned flight. SLS is designed to allow the first visit by humans to an asteroid and, 【C6】________, to Mars.
    "This is just the first of what will be a long line of exploration missions beyond low Earth orbit, and in a few years we will be sending our astronauts to destinations humans have never experienced," said Bill Hill, deputy associate administrator for Exploration Systems Development, in a statement. "It’s【C7】________to be a part of the journey now, at the beginning."
    While NASA has big plans for Orion, manned missions are not planned till after 2020, so a Mars【C8】________may not be possible until the later 2020s or 2030s. Though 3,600 miles is the longest trip in quite some time, Mars is an【C9】________140 million miles away, and much work is needed to ensure the craft can be safe and【C10】________enough for a crew to make that extremely long space journey.
【C8】
选项
答案L
