A student researching the Voyager missions has taken the following notes:
• Voyager 1 and 2 were launched by NASA in 1977 • Both spacecraft have now entered interstellar space • Voyager 1 is the most distant human-made object from Earth • The spacecraft carry golden records with sounds and images from Earth • Both Voyagers continue to transmit data back to Earth over 45 years later
The student wants to emphasize the longevity and continued operation of the Voyager missions. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Both Voyager spacecraft carry golden records containing sounds and images representing life on Earth.
Voyager 1 is now the most distant human-made object from Earth, having entered interstellar space.
Over 45 years after their 1977 launch, both Voyager spacecraft continue to transmit scientific data back to Earth.
