WebThe aerodynamic deceleration will be accomplished by a mortar-deployed 21.5-m Viking-type disk-gap-band parachute (DGB), and will be the largest extra-terrestrial decelerator in the history of space exploration [1]. The parachute will deploy at up to Mach 2.2 and 750 Pa, resulting in the highest load and speed experienced by a parachute on Mars. WebNext, case 2 (Fig. 1b) simulates a traditional and actual DGB parachute. However, in case 2, suspension lines between the disk and band are omitted because they are extremely thin (please see Refs. [6,10] for their influences). Thus, the gap in case 2 is continu-ous. This is the main difference between case 1 and case 2. slow release vitamin c 1500 mg
