A
Scientists never stop studying the universe. In 2005, scientists saw pictures of Titan, the largest moon of Saturn(土星). They showed mountains as well as lakes on Titan. After studying the pictures, the scientists got very glad. They found there could be life on Titan.
Now, NASA agrees to pay for Turtle's team to build a space craft (航天器) called Dragonfly. Turtle is a scientist at the Johns Hopkins Applied Physics Laboratory, in Maryland.
Dragonfly will go to space in 2026, and it will land on Titan 8 years after it goes to space. It will collect and send information back to the earth.
Scientists at NASA's Jet Propulsion Laboratory, in California, are also making a robot called Shapeshifter. It will also go to Titan. On Titan, it will move along until it comes to something big, such as a mountain. Then it will become two drones(无人机). They'll fly around and collect information. Then they'll meet again on the other side. Scientists are also imagining a Shapeshifter made of 12 drones. They'll go under water, too.
Scientists can't know for sure where they'll find something about life on Titan, but they all have hope in their heart.
