Read the passage.

My work on scientific development teams for 27 years prepared me for the Cassini mission. My team’s goal was to get a better understanding of Titan, Saturn’s largest moon, by using the space probe designed by the European Space Agency. The Cassini spacecraft carried the space probe in 2005. Once it detached and entered Titan’s atmosphere, it collected more information than we expected.
