Tell about Apollo Program ?

The first flights used the smaller Saturn I (1) B rocket.

Apollo was the NASA program that resulted in American astronauts' making a total of 11 spaceflights and walking on the moon.

The first four flights tested the spacecraft. Six of the other seven flights landed on the moon. The first moon landing took place in 1969. The last moon landing was in 1972.

It was about as tall as a 22-story building.

NASA built the Apollo Command Module for this program. It had room for three astronauts. The crew area had about as much room as a car. They rode in it on the way to the moon and back.

The first four flights tested the equipment used in the Apollo Program. Six of the other seven flights landed on the moon. The first Apollo flight happened in 1968. The first moon landing took place in 1969. The last moon landing was in 1972.

This rocket had two stages. That means it was made of two parts. When the first part ran out of fuel, it dropped away from the other and burned up in Earth's atmosphere.

Another spacecraft, the Lunar Module, was used for landing on the moon. This spacecraft carried two astronauts. It took them from orbit around the moon to the moon's surface. The Lunar Module also carried them back into the moon's orbit to the Command Module.

NASA designed the Apollo Command Module for this program. It was a capsule with room for three astronauts. The astronauts rode in the Command Module on the way to the moon and back. It was larger than the spacecraft used in the Mercury and Gemini programs. The astronauts had room to move around inside the spacecraft. The crew area had about as much room as a car.

The second part continued flying.

The first Apollo flight used the smaller Saturn IB rocket. This rocket had two stages. That means it was made of two parts. When the first part ran out of fuel, it dropped away from the other. It burned up in Earth's atmosphere.

The Saturn IB rocket was used to test the new Apollo capsule in Earth orbit.

The other flights used the more powerful Saturn V (5) rocket.

The other flights used the more powerful Saturn V (5) rocket. This three-stage rocket sent the Apollo spacecraft to the moon. It was about as tall as a 36-story building.

The second part kept flying. The Saturn IB rocket was used to test the Apollo capsule in Earth orbit. It was about the size of a 22-story building.

This three-stage rocket sent the Apollo spacecraft to the moon.

When Did Humans First Visit the Moon?
The first manned mission to the moon was Apollo 8. It circled around the moon on Christmas Eve in 1968. However, Apollo 8 did not land on the moon. It orbited the moon, then came back to Earth. The crew was Frank Borman, Bill Anders and Jim Lovell.

In 1961, President John F. Kennedy said he wanted America to land astronauts on the moon. He wanted it to happen during the 1960s.

NASA did this with the Apollo program. It was the first time people had left Earth orbit and visited another world. These trips will help NASA explore other worlds later.

It was about as tall as a 36-story building.

The first moon landing occurred on July 20, 1969, on the Apollo 11 mission. The crew of Apollo 11 was Neil Armstrong, Michael Collins and Buzz Aldrin. Armstong and Aldrin walked on the lunar surface while Collins remained in orbit around the moon. When Neil Armstrong became the first person to walk on the moon, he said, "That's one small step for (a) man; one giant leap for mankind."

The first manned mission to the moon was Apollo 8. It circled around the moon on Christmas Eve in 1968.

Apollo 13 is one of the more famous lunar missions. A movie was made about this flight. Apollo 13 was supposed to land on the moon. On the way there, the spacecraft had a problem. NASA had to figure out how to bring the astronauts home safely. Apollo 13 flew all the way around the moon before returning home. Despite the problem, they were able to land safely on Earth.

Apollo’s moon mission was one of the most expansive government initiatives in American history. During its peak years, some 34,000 NASA employees and 375,000 outside contractors took part in the program.

However, Apollo 8 did not land on the moon. It orbited the moon, then came back to Earth.
