Crew Capacity: 1
Delta v: 2.27 km/s
AG 1: Engine
AG 7: Reentry Mode
Its delta v is enough to take off from the lunar surface(RSS), enter the lunar 450 km circular orbit for docking, refuel and return to the earth. It's also working well in Juno system.
AG 7 needs to be activated before entering Earth's or Droo's atmosphere, and the landing process will be done automatically.
Note: Before activating AG 7, the periapsis must be below 20km to prevent the craft from heat damage or explotion.
If the surface velocity is about 10.6 km/s when reaching the edge of Earth’s atmosphere and the periapsis is 20 km, heat shield will remain about 950. During the landing process, drood's maximum overload will exceed 20 Gs.
