SUMMARY
Plasma generation during the reentry of space vehicles into Earth's atmosphere is primarily caused by the extreme heat resulting from air drag and compression. As vehicles descend at hypersonic speeds, diatomic gases such as oxygen and nitrogen dissociate due to the intense heat, leading to the formation of ions. While pressure changes contribute to the heating, it is the heat itself that initiates the ionization process, confirming that energy is essential for gas ionization rather than pressure alone.
