Which sentence best expresses the central idea of the passage? Juno Reaches Jupiter
adapted from NASA
After an almost five-year journey to the solar system's largest planet
, NASA's Juno spacecraft successfully entered Jupiter's orbit during a
35-minute engine burn. Confirmation that the burn had completed was received on Earth at 8:53 p.m. PDT, Monday, July 4, 2016. Juno's
principal goal is to understand the origin and evolution of Jupiter. With its suite of nine science instruments, Juno will investigate the existence
of a solid planetary core. It will also map Jupiter's intense magnetic field, measure the amount of water and ammonia in the deep atmosphere,
and observe the planet's auroras. The mission also will let us take a giant step forward in our understanding of how giant planets form and the
role these titans played in putting together the rest of the solar system. As our primary example of a giant planet, Jupiter also can provide critical
knowledge for understanding the planetary systems being discovered around other stars.
