1.
He proved Copernicus heliocentric theory by using a telescope.
Correct Answer
A. Galileo
Explanation
Galileo is the correct answer because he used a telescope to observe the heavens and gather evidence to support Copernicus' heliocentric theory. By observing the movements of the planets and the phases of Venus, Galileo provided empirical evidence that supported the idea that the Earth revolves around the Sun. This challenged the prevailing geocentric model proposed by Aristotle and Ptolemy and confirmed Copernicus' theory.
2.
Believed in the earth-centered model (geocentric) and that planets follow elliptical orbits.
Correct Answer
C. Ptolemy
Explanation
Ptolemy believed in the earth-centered model (geocentric) and that planets follow elliptical orbits. This is evident from his work "Almagest" where he presented a comprehensive mathematical model of the universe based on this belief. Ptolemy's geocentric model was widely accepted for centuries until it was challenged by Copernicus' heliocentric model.
3.
Believed in the earth-centered model of the universe and that planet had elliptical orbits.
Correct Answer
B. Aristotle
Explanation
Aristotle believed in the earth-centered model of the universe and that planets had elliptical orbits. He proposed that the Earth was at the center of the universe, with all other celestial bodies revolving around it in perfect circular orbits. This geocentric model was widely accepted for centuries until it was later challenged by Copernicus and Galileo, who proposed the heliocentric model with the sun at the center. However, Aristotle's ideas were influential in shaping the understanding of the cosmos during his time.
4.
First to believe in a sun-centered universe (heliocentric), also believed that planets followed circular orbits.
Correct Answer
D. Copernicus
Explanation
Copernicus was the first to believe in a sun-centered universe (heliocentric) and also believed that planets followed circular orbits. This belief challenged the prevailing geocentric model proposed by Ptolemy and supported by Aristotle. Copernicus' theory, known as the Copernican model, revolutionized our understanding of the solar system and laid the foundation for modern astronomy.
5.
Things fall because of __________
Correct Answer
gravity
Explanation
Objects fall because of the force of gravity. Gravity is a natural phenomenon by which all things with mass or energy are brought toward one another. It is the force that pulls objects towards the center of the Earth. When an object is dropped, the force of gravity acts on it, causing it to accelerate towards the ground. This is why things fall downwards instead of floating or moving upwards.

Correct Answer
C. Yuri Gagarin
Explanation
Yuri Gagarin is the correct answer because he was the first man to travel into space. On April 12, 1961, Gagarin successfully completed a single orbit around the Earth aboard the Vostok 1 spacecraft, making him a pioneering figure in the history of space exploration. His achievement marked a significant milestone in human spaceflight and opened the door for further advancements in space exploration.
10.
He was the first US man to orbit the earth.
Correct Answer
D. John Glenn
Explanation
John Glenn is the correct answer because he was the first US man to orbit the earth. This achievement took place on February 20, 1962, when Glenn piloted the Friendship 7 spacecraft as part of NASA's Mercury-Atlas 6 mission. He successfully completed three orbits around the Earth, making him a pioneer in space exploration and a national hero. Glenn's historic feat paved the way for future space missions and contributed significantly to the advancement of space technology.
11.
The first US manned Space program.
Correct Answer
A. Mercury
Explanation
Mercury was the first US manned space program. It was initiated in 1958 and aimed to put a human in orbit around the Earth. The program consisted of six manned flights between 1961 and 1963, with the first American astronaut, Alan Shepard, being launched into space in 1961. The Mercury program laid the foundation for future space exploration and paved the way for the subsequent Gemini and Apollo programs, which aimed to achieve more ambitious goals such as spacewalks and lunar landings.
12.
The name of the Russian Space Station that was in operation for 15 years was named _______
Correct Answer
Mir
mir
Explanation
The correct answer is "Mir" or "mir". Mir was the name of the Russian Space Station that was in operation for 15 years.
13.
The _________________is designed to transport astronauts to and from a space station.
Correct Answer
Space Shuttle
space shuttle
spaceshuttle
Explanation
The space shuttle is specifically designed to transport astronauts to and from a space station. It is a reusable spacecraft that can be launched into space multiple times, carrying both crew members and cargo. The space shuttle played a crucial role in the development of the International Space Station (ISS) and was used for various missions, including satellite deployment, scientific research, and space exploration. Its unique design allowed for the safe transportation of astronauts and equipment to and from the Earth's orbit.
14.
Robert Goddard first built and launched a _________________ filled rocket.
Correct Answer
liquid
Explanation
Robert Goddard first built and launched a liquid-filled rocket. This means that the rocket was powered by a liquid fuel, rather than a solid or gas fuel. Liquid-fueled rockets have the advantage of being able to be controlled and throttled, allowing for more precise and efficient propulsion. This was a significant development in the field of rocketry, as it laid the foundation for future advancements in space exploration and technology.
