a. Rossetta
b. Juno
c. Cassini
d. Philae

ANSWER: Philae
 
Since Rosetta has lost contact with Philae 7 months ago, it has been balancing science observations with comet landing finale even though the lander has remained quiet since July 2015. Insufficient light falling on Philae’s new home for charging its second battery is the reason this lander has fallen into hibernation.
