Spacecraft is close to a comet - level 2
People launched a spacecraft in March 2004. It traveled more than 4 billion miles (6.4 billion kilometres) since then.
At first, it moved between the Earth and Mars because the right direction had to be set. Now, the 10-year journey comes to an end, and the real science can begin. The spacecraft is only 100 kilometres from the comet, so experts can start analysing and measuring it.
They want to find out what its history is and what it’s made of. It could even answer some questions about the birth of the solar system or life itself.
Difficult words: launch (to begin the journey), analyse (study), measure (to find the size of something), solar system (our planet, the sun and other planets near to Earth exist here).
You can read the original story and watch the video in the Level 3 section.
