Question 14
14.

You are working on a team that monitors and controls a communications satellite in a low-Earth orbit. A team of astronauts is dispatched to add some additional hardware to the satellite so that it can collect new data. The astronauts accidently break off part of the satellite during docking, losing that part. The piece is of significant size but was mainly used for the launch. The astronauts are able to repair the break and install the new hardware. The satellite remains fully functional.

The piece of the satellite that was lost is a significant piece of debris. Who is responsible for what happens to he broken piece of satellite that was lost?

Question 15
15.

Match the definition to the correct term.

Draggable itemarrow_right_altCorresponding Item

arrow_right_alt
Inclination
The point in the orbit of an object (such as a satellite) orbiting the earth that is the closest to the center of the earth.
arrow_right_alt
Eccentricity
The point in the orbit of an object (such as a satellite) orbiting the earth that is at the greatest distance from the center of the earth.
arrow_right_alt
Semi-Major Axis
Describes the size of an orbit. For circular orbits, altitude is often used in place of this term.
