Which of the following was one of Dr. Robert Goddard's primary contributions?

• A. Developed satellite navigation systems
• B. Proved that rockets can work in a vacuum
• C. Introduced solar power for spacecraft
• D. Discovered the first exoplanet

Answer: (B)

Dr. Robert Goddard is often referred to as the father of modern rocketry due to his pioneering work in the early 20th century. One of his primary contributions was proving that rockets could function in a vacuum, which was a crucial concept for future space travel. Goddard conducted experiments that demonstrated the principles of rocket propulsion, leading to the understanding that rockets do not rely on atmospheric oxygen but can generate thrust in the absence of air. This finding was foundational because it validated the concept of space exploration beyond Earth's atmosphere, allowing future missions to be conceived and undertaken outside of the constraints of Earth's environment. His work laid the groundwork for later developments in space travel and is integral to our current capabilities in aerospace technology.
