ExoMars mission - level 1
People launch a rocket. They launch it from Kazakhstan. It is a Russian rocket. It carries two probes into space.
The probes are European. This is the ExoMars mission. The European Space Agency organises it.
The probes are going to Mars. That takes seven months. When they are close to Mars, the probes separate. One probe goes down to Mars. The other one moves around the planet. It gets information about the atmosphere.
Difficult words: launch (to go up), probe (a spacecraft which gets information about something; there are no people on the spacecraft), separate (to go apart).
