The data indicates that the water on Comet 67P/Churyumov-Gerasimenko is different from the water on Earth, suggesting that comets may have played a significant role in delivering water to our planet.
Structure
Rosetta discovered that Comet Churyumov-Gerasimenko has a surprisingly complex structure. It has two lobes connected by a narrow neck and is covered in pits, boulders, and cliffs. This discovery was unexpected as scientists had previously believed that most comets were relatively uniform in shape.
Organic Compounds
Another exciting discovery made by Rosetta was the detection of organic compounds on Comet 67P/Churyumov-Gerasimenko’s surface. These molecules are the building blocks of life and their presence suggests that comets may have played a role in bringing these essential materials to Earth billions of years ago.
End Of Mission
After over twelve years of operation, Rosetta's mission came to an end in September 2016 when it deliberately crashed into Comet Churyumov-Gerasimenko's surface. Scientists decided to do this as it would provide them with one final opportunity to gather data about this comet up close before it passed out of range.
Challenges Faced During the Mission
The Rosetta Mission Program was undoubtedly one of the most challenging space missions ever attempted. From navigating through deep space to deploying a robotic lander on a distant comet, this mission faced several obstacles along the way. In this section, we will explore some of the primary challenges that scientists and engineers had to overcome during this mission.
### Navigating Through Deep Space
One of the biggest challenges that Rosetta's team faced was navigating through deep space accurately.
