After two minutes of aerodynamic breaking — now some 400 kilometres below the entry interface, and with the probe having slowed to the speed of sound — a mortar was programmed to deploy the small drogue into the slipstream, and once the drogue had slowed the probe to 430 kilometres per hour the afterbody shield was to be released so that the 2.5-metre wide dacron main parachute could be deployed.
