Beagle 2, the British Mars lander due for launch in May 2003, carries a hot-film wind sensor which will measure wind speed (up to 30 m/s) and horizontal component of wind direction. The position of the wind and air temperature sensors at the end of a motorised arm allows measurement possibilities that were unavailable in previous missions. The sensors will be operated at several heights between ~20 cm and ~100 cm above the lander body. This will allow direct measurement of the near-surface wind and temperature profiles, and their associated turbulence spectra. Convective updrafts are expected to form above the heated lander, as it may get up to 80 degrees hotter than the surrounding air. Scaled laboratory experiments suggest that these are likely to be intermittent (thermals), rather than steady-state (plumes). These will be studied on Mars by taking horizontal scans at selected heights as well as the vertical profiles mentioned above. The wind sensor was calibrated in a low-density wind tunnel facility, in which Martian surface wind conditions are simulated. Wind speeds of 0 - 30 m/s were created in a CO2 or air atmosphere at pressures of 5 - 10 mbar.
