ation D. New Film Rating System Against some Unhealthy Western Films C A historic journey across the Solar System reached its end on Friday as a little probe (探测器 )took a big step for human knowledge. The US $ 3 billion CassiniHuygens mission(使命 ), a joint project of NASA and the European and Italian space agencies was launched in 1997 from Cape Canaveral, Florida, to study Saturn, its rings, its moons and its magosphere(磁层 ) — which surrounds it. Huygens was named after the Dutch scientist who discovered Titan in 1655, NASA officials said. Some science team members monitoring the flight at the European Space Agency39。 s Space Operations Centre in Darmstadt, Germany, have waited tens of years to see the first of 750 pictures and other scientific readings from the yellow skied moon. I have been in this mission almost 21 years and I39。 m very excited, ESA mission manager Jean Pierre LeBreton said at a news conference on Thursday. “I’m also quite sure we arc going to see something very special tomorrow (on Friday) Timers inside the probe will awaken it just before it enters Titan39。 s atmosphere. Huygens is shaped like a wok(锅 ) and covered with a heat shield(防护装置 ) so that it can survive the extreme heat that it will face upon entry. It will then unfold a series of parachutes to slow its fall to the moon39。 s reddish surface, expected to take about hours. As it goes down, the probe will lose its heat shield and unfold its special camera and instruments to begin collecting information on wind speeds and the makeup of Titan39。 s atmosphere. This is the moment scientists have been waiting for. This data will then be sent back to Cassini, which will relay it to NASA’s Deep Space Network in California and on to ESA controllers in Darmstadt German. Scientists believe the anic chemical reaction taking place on Titan are similar to the process that gave rise to life on Earth. Its atmosphere is mostly nitrogen, like Earth, but its surface temperature of about minus 180℃ makes it improper to life. Titan, believed to be the only moon in the solar system with an atmosphere, is larger than the plas Mercury and Pluto. 64. Huygens was named after . A. an ESA mission manager B. a Dutch scientist who discovered Saturn in 1655 C. an astronomer who first discovered Titan D. scientists from NASA and the European and Italian space agencies 65.
