While researching a topic, a student has taken the following notes:
  • In 1977, NASA launched the twin probes Voyager 1 and Voyager 2 to explore the outer solar system.
  • Both spacecraft took advantage of a rare planetary alignment to conduct flybys of Jupiter and Saturn.
  • Voyager 2 continued onward to complete the first flybys of Uranus (1986) and Neptune (1989).
  • In 2012, Voyager 1 crossed the heliopause and entered interstellar space.
  • In 2018, Voyager 2 also crossed into interstellar space.
  • Both probes continue to transmit scientific telemetry back to Earth using the Deep Space Network.
The student wants to provide a chronological overview of the Voyager mission’s primary exploration milestones. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A
Launched in 1977 to explore the outer planets, the Voyager probes completed flybys of Jupiter and Saturn before crossing the heliopause into interstellar space in 2012 and 2018.
B
NASA took advantage of a rare planetary alignment in 1977 when launching the Voyager spacecraft to study Jupiter and Saturn.
C
Although Voyager 2 made historic flybys of Uranus and Neptune in the 1980s, both probes now use the Deep Space Network to send data.
D
Voyager 1 became the first human-made object to reach interstellar space when it crossed the heliopause in 2012.
