WebIt's reentry speed is much faster, a little over 11,000 meter/second! The higher speed comes from the fact that the spacecraft must fly fast enough to completely leave Earth orbit. That makes the reentry heating problem even more difficult. NASA is now working on developing new materials that can survive such speeds for the new Orion spacecraft. 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.
