Question 5

Mission controllers transfer a scientific spacecraft between two circular orbits around Saturn. The spacecraft is in a stable orbit before and after the transfer. Which statement is correct?

[1]
A

A greater orbital speed after the transfer means a larger orbital radius.

B

Any change in orbital speed prevents the second orbit from being stable.

C

A greater orbital speed after the transfer allows either a larger or a smaller orbital radius.

D

A greater orbital speed after the transfer means a smaller orbital radius.
