A base view of the Descent Module, installed in ground support equipment with additional wiring of temperature sensors for testing. The many rivetted plates around the periphery are the spin vanes, small angled 'winglets' that will turn the DM at 1-20 rev./min. as it descends. The two smaller circular inserts near the dome's centre are the gas inlets for the Aerosol Collector Pyrolyser and Gas Chromatograph/Mass Spectrometer. Inside the largest circular aperture are the Surface Sensor Package's sensors. [Image Date: 01-01-97] [97.05.006-002]
