Do You Know Moon Facts?

Explanation
In 1969, the first man set foot on the moon. This historic event took place during the Apollo 11 mission, with astronaut Neil Armstrong becoming the first person to walk on the lunar surface. The successful moon landing marked a significant milestone in human space exploration and is widely celebrated as one of the greatest achievements in history.

Explanation
The statement is true because the Moon is indeed Earth's only natural satellite. A natural satellite is a celestial body that orbits around a planet or a dwarf planet. While there are other objects in space that orbit around Earth, such as artificial satellites, space debris, and even some asteroids temporarily captured by Earth's gravity, the Moon is the only natural satellite that permanently orbits our planet. It plays a significant role in Earth's tides, stabilizes its axial tilt, and has been a subject of fascination and exploration throughout human history.

Explanation
The force of gravity on the moon is not about 6 times the force of gravity on Earth. In fact, the force of gravity on the moon is about 1/6th the force of gravity on Earth. This is because the moon has less mass than Earth, resulting in a weaker gravitational pull.

Explanation
The correct answer is 20 tons (40,000 pounds). This is because over the course of the US and Russian lunar missions, various spacecraft and equipment were left on the moon's surface. These include lunar rovers, lunar modules, and other debris. The accumulated weight of all these items is estimated to be around 20 tons or 40,000 pounds.

Explanation
The statement is true because JFK did indeed challenge the US to visit the moon in a speech in 1961. This challenge led to the establishment of the Apollo program by NASA, which successfully achieved the goal of landing astronauts on the moon in 1969, just 8 years after the challenge was issued.

Explanation
Lunar eclipses occur at the new moon because during this phase, the moon is positioned between the sun and the Earth, causing the Earth's shadow to fall on the moon. This alignment allows for the moon to be in the perfect position for a lunar eclipse to occur. During a lunar eclipse, the moon appears darkened or reddish in color as it passes through the Earth's shadow.

Explanation
The correct answer is 1/4. This means that the Moon is approximately one-fourth the size of Earth.

Explanation
Each Apollo mission cost about $4 million. This was a significant amount of money at the time, considering the technological advancements and resources required for space exploration. The high cost can be attributed to various factors such as the development and testing of spacecraft, astronaut training, mission operations, and scientific research. The Apollo program was a massive undertaking that aimed to achieve ambitious goals, including landing humans on the moon, and this required substantial financial investment.
