2.
In what year was the first artificial earth satellite launched?
Correct Answer
B. 1957
Explanation
In 1957, the first artificial earth satellite was launched. This marked a significant milestone in space exploration and technology. The launch of the satellite, named Sputnik 1, was conducted by the Soviet Union. It was a small, spherical spacecraft that orbited the Earth and transmitted radio signals back to Earth. This event not only demonstrated the Soviet Union's technological capabilities but also ignited the Space Race between the United States and the Soviet Union.
3.
What was the first scientific discovery made with instruments orbiting space?
Correct Answer
B. Van Allen radiation belts
Explanation
The Van Allen radiation belts were the first scientific discovery made with instruments orbiting space. These belts are regions of high-energy particles trapped by Earth's magnetic field. They were discovered in 1958 by the Explorer 1 satellite, the first successful American satellite. The discovery of these radiation belts provided valuable insights into the nature of Earth's magnetic field and its interaction with charged particles from the Sun.
4.
What was the name of the first U.S. spacecraft to escape Earth's gravitational pull?
Correct Answer
C. Pioneer 4
Explanation
Pioneer 4 was the first U.S. spacecraft to escape Earth's gravitational pull. This spacecraft was launched on March 3, 1959, by NASA. It successfully flew by the Moon, becoming the first U.S. spacecraft to do so, and continued on into orbit around the Sun. This achievement marked an important milestone in space exploration as it demonstrated the capability of spacecraft to leave Earth's gravitational field and travel to other celestial bodies.
5.
What led to the "Space Race?"
Correct Answer
B. The launch of Sputnik I
Explanation
The correct answer is the launch of Sputnik I. The Space Race was a competition between the United States and the Soviet Union to achieve milestones in space exploration. The launch of Sputnik I, the first artificial satellite, by the Soviet Union in 1957 marked the beginning of this race. It caused a sense of urgency and fear in the United States, as they saw the Soviet Union's technological advancements as a threat to national security. This led to increased funding for space exploration and the eventual landing of American astronauts on the moon.
6.
________________ was the first country to launch a satellite into space.
Correct Answer
Russia
Soviet Union
USSR
U.S.S.R.
the Soviet Union
Explanation
The correct answer is the Soviet Union. The Soviet Union was the first country to successfully launch a satellite into space with the launch of Sputnik 1 on October 4, 1957. The satellite marked the beginning of the Space Age and the start of the space race between the Soviet Union and the United States.
7.
How many satellites are required by a GPS?
Correct Answer
24
Explanation
A GPS (Global Positioning System) requires a minimum of 24 satellites to provide accurate positioning and navigation information. These satellites are distributed in six orbital planes, with four satellites in each plane. By having this number of satellites, the GPS system ensures that at least four satellites are visible from any point on Earth at any given time, allowing for precise location calculations. Therefore, 24 satellites are necessary for the GPS to function effectively.
8.
Who was the first human to go into space?
Correct Answer
A. Yuri Gagarin
Explanation
Yuri Gagarin is the correct answer because he was the first human to go into space. On April 12, 1961, Gagarin, a Soviet cosmonaut, successfully completed a single orbit around the Earth aboard the Vostok 1 spacecraft. This historic achievement made him a pioneer in space exploration and opened up new possibilities for human space travel. Lance Armstrong is a professional cyclist, Gary Yury is not a known individual, and Neil Armstrong was the first person to walk on the moon, not the first to go into space.
9.
The launch of which U.S. satellite in 1989 provided strong support for the big bang theory?
Correct Answer
D. Cosmic Background Explorer
Explanation
The Cosmic Background Explorer (COBE) satellite, launched in 1989, provided strong support for the big bang theory by detecting and measuring the cosmic microwave background radiation (CMB). This radiation is considered a remnant of the early universe and its discovery was a major breakthrough in understanding the origins and evolution of the universe. The COBE mission's measurements of the CMB provided valuable data that confirmed the predictions of the big bang theory and contributed to our current understanding of the universe's formation.
10.
Which U.S. president began the U.S. Space Program?
Correct Answer
C. Kennedy
Explanation
Kennedy is the correct answer because he is widely recognized for his role in initiating and promoting the U.S. Space Program. In 1961, Kennedy made a historic speech where he set the goal of landing a man on the moon before the end of the decade. This led to the establishment of NASA's Apollo program, which successfully achieved this goal with the Apollo 11 mission in 1969. Kennedy's vision and support were instrumental in launching the U.S. Space Program and shaping its future direction.
11.
Which country was the first to send a spacecraft in the vicinity of other planets?
Correct Answer
D. United States
Explanation
The United States was the first country to send a spacecraft in the vicinity of other planets. This can be attributed to the successful Mariner program, launched by NASA in the 1960s. The Mariner 2 spacecraft was the first to fly by another planet, Venus, in 1962. This achievement marked a significant milestone in space exploration and paved the way for future missions to explore other planets in our solar system.
12.
What was the name of the first U.S. satellite?
Correct Answer
B. Explorer I
Explanation
Explorer I was the name of the first U.S. satellite. The other options listed, Reconnaissance, Mercury, and Orion, are not correct as they do not refer to the first U.S. satellite.
13.
What does ISS stand for?
Correct Answer
International Space Station
Explanation
ISS stands for International Space Station. The International Space Station is a habitable space station that serves as a laboratory for scientific research and international cooperation in space exploration. It is a joint project between NASA, Roscosmos, JAXA, ESA, and CSA, and has been continuously occupied since November 2000. The ISS orbits the Earth and provides a platform for various experiments and studies related to biology, physics, astronomy, and other scientific disciplines. It also serves as a base for astronauts to live and work in space for extended periods of time.
14.
Which space visionary described a way in which 3 satellites could relay communications in orbit about 35,800 km?
Correct Answer
B. Arthur C. Clarke
Explanation
Arthur C. Clarke is the correct answer because he was a space visionary who proposed the concept of geostationary satellites in 1945. He described a way in which three satellites could be placed in orbit approximately 35,800 km above the Earth's equator, allowing them to remain stationary relative to a specific point on the ground. This concept, known as the Clarke Orbit, revolutionized telecommunications and is still widely used today.
