Describe how gravity assist helped Juno achieve its mission. Question 4Select one: a. Juno was being pulled toward the inner planets by the sun's gravity, but as it orbited the earth, it sped up giving it enough momentum to head back out to Jupiter. b. Juno had enough energy to get to the planet Jupiter, and performed a slingshot maneuver around the immense gas giant in order to gain enough momentum to return to Earth. c. Juno lost the fuel required to reach Jupiter, so it used the enormous gravity of the sun to accelerate around the sun and to Jupiter in order to complete its mission. d. Juno conserved fuel by using the gravity of the gas giant Jupiter to travel to it
