5. a PROBE designed to measure THE HEAT BENEATH Mars’s surface.
6. two terrestrial [təˈrestriəl] years

7. It will also RECORD meteorite [ˈmi:tiəraɪt] impacts.
8. The number of Marsquakes will indicate HOW GEOLOGICALLY ACTIVE THE PLANET IS.
9. Analysing the VIBRATIONS those QUAKES AND METEORITES GENERATE will GIVE CLUES ABOUT the composition of the Martian interior.
