WebFeb 3, 2024 · The Earth itself, with its atmosphere, is spinning eastward below you, at around 1,000 mph. So, you can reduce your re-entry speed by orbiting in the same direction that the Earth spins.... WebMar 21, 2024 · The mechanical expansion reentry vehicle has become the focus of deep space exploration because of its good deceleration effect and high stability. However, due to its special aerodynamic shape, its surface heat flux characteristics are different from traditional reentry vehicles. In this paper, the Two-Temperature model is introduced to …
