That really depends on the nature of the space plane and the technology used.
The shuttle (a space plane) reduced the cost of space flight dramatically and made the payloads larger. But it was mainly due to the reusability and size of the shuttle.
hi space material that falls to earth
The space between cells can be called the extracellular space, the extracellular material, or the extracellular matrix. This space is not a vacuum; it is filled with material. If the material is gel-like it is called the ground substance, which is filled with many dissolved solute particles, and the tissue will be loose. If the material in the extracellular space has some fibers of protein in it, the entire tissue will have a stronger consistency.
Not unless there's some material matter in the space.
shearing
An interstellar cloud.
Not necessarily. A sphere is a "space" figure, but is not made up of planes.
The density does not change, as density is the amount of material in a given amount of space. But each piece has the same amount of space and material relative to each other.
Some planes have only one intercept.
Space planes will go up now that the space shuttle program was dropped. :(
If there are two unique, non-parallel planes in space, they will intersect, and their intersection will be a line.
Prism
Given a line, there are an infinite number of different planes that it lies in.

Then they don't go into space
A plane midway between the two given planes and parallel to them.
Radio waves will be reflected by any surface where the electromagnetic properties of the space change. e.g. moving from free space into solid material.
Two planes do not intersect at all if the planes are parallel in three-dimensional space.
