What was the first artificial Earth satellite, launched by the Soviet Union in 1957, which intensified the space race?

• A. Luna
• B. Sputnik
• C. Vostok
• D. Gagarin

Answer: (B)

The focus is on identifying the first artificial Earth satellite and its impact on the space race. Sputnik, launched by the Soviet Union in 1957, became the first human-made object to orbit Earth. That achievement showed a new level of technological capability and sparked a rapid race to explore space between the Soviets and the United States. The launch led to increased investments in rocketry and science, and it helped catalyze the creation of NASA and numerous subsequent satellite and human spaceflight programs. Luna refers to Soviet lunar missions, not an Earth-orbiting satellite. Vostok was the spacecraft that carried the first human in space, Yuri Gagarin, and Gagarin is the name of the astronaut, not a satellite. So Sputnik best fits the description as the first artificial satellite that intensified the space race.
