WebHigh velocity entry into Martian air creates a CO2-N2plasma, as opposed to O2-N2for Earth air.[1] Mars entry is affected by the radiative effects of hot CO2gas and Martian dust suspended in the air.[2] Flight regimes for entry, descent, and landing systems include aerocapture, hypersonic, supersonic, and subsonic. [3] Overview[edit] Reentry has been achieved with speeds ranging from 7.8 km/s for low Earth orbit to around 12.5 km/s for the Stardust probe. Crewed space vehicles must be slowed to subsonic speeds before parachutes or air brakes may be deployed.
