Spacecraft Cylinder is most suitable for circumterraneous and Space transportations. Under condition of enough preliminary detection of a dangerous asteroid it is used for space flight against asteroids. The technology of control Gravity and Inertia of the spacecraft ("Spacecraft Cylinder" see) allows in the process of space flight to exclude shocks of the spacecraft against Earth at its landing or at its mooring to an asteroid. It allows also at a pursuit of the dangerous asteroid, which able to move with velocity V₂ ("Spacecraft Cylinder" see above), to catch up with it for account of the spacecraft velocity, greater of the asteroid velocity. By that the space flight direction of the craft is provided with the resorts featured in the (Spacecraft  Ambrella).
