Dear Adel,

In the response to your question about the main challenges for engineers in vehicle construction for Venus:

1. High temperature (~450 C).

2. Atmosphere pressure (93 P).

3. Atmospheric density (70 kg/m3).

4. Dense layer of clouds ( H2SO4 ), which hide visibility of the surface.

5. Strong zonal winds from E to W ~100 m/s at the clouds level. Wind velocity near the surface (~1 m/s).

Thank you Sergey Krasilnikov for the data
