Which space agency launched the Voyager missions?

• A. ESA
• B. Roscosmos
• C. JAXA
• D. NASA

Answer: (D)

NASA is the U.S. space agency that launched the Voyager missions, which were designed to study the outer planets and then continue into interstellar space. Launched in 1977, Voyager 1 and Voyager 2 were sent into space on Atlas-Centaur rockets and are managed by NASA’s Jet Propulsion Laboratory, enabling a grand tour of Jupiter and Saturn and their moons. The European Space Agency, Roscosmos, and JAXA are European, Russian, and Japanese space organizations with their own programs, but they did not launch Voyager. That’s why NASA is the correct answer.
