Answer- B
On April 14th at 8:14 a.m. ET, the European Space Agency (ESA) launched the Jupiter Icy Moons Explorer (Juice) mission from Europe’s spaceport in Kourou, French Guiana, using an Ariane 5 rocket.
The primary objective of the Juice mission is to study Jupiter and three of its largest moons. The ESA received a signal from Juice about an hour after the successful separation from the Ariane 5 rocket, confirming that communication has been established between the vehicle and Earth-based mission control.
