2019-1-9An octant, also called "reflecting quadrant", is a measuring instrument used primarily in navigation.It is a type of reflecting instrument that uses mirrors to reflect the path of light to the observer and, in doing so, doubles the angle measured. This allows the instrument to use a one-eighth circle arc to measure a quarter circle or quadrant.

As the delta-V for a mission goes up, the amount of propellant required goes up exponentially (or looking at it another way: the amount of payload shrinks exponentially).Large amounts of propellant are expensive, but the higher the mass-ratio the higher the likelihood that the spacecraft will not be resuable.
