# Why did the Apollo astronauts not fall off the Moon?

Contents

You’ve seen films of the APOLLO astronauts walking around on the Moon, why didn’t they fall off? About 20 percent of the people changed their answer to the first question when they heard this one! But the most amazing part was that about half of them confidently answered, “Because they were wearing heavy boots.”

## Why didn’t astronauts float off the Moon?

The moon has a surface gravity approximately one sixth that of the earth. So for the astronauts to “float away” they would need to jump with an initial velocity of almost 2.5 km/sec (slightly over 5000 miles an hour) – difficult, even without a heavy spacesuit!

## How did they walk on the Moon if there is no gravity?

Astronauts trained for microgravity by walking “sideways.”

Armstrong practiced taking off and landing in the Lunar Landing Training Vehicle in Houston. And, to simulate walking in the moon’s lower-gravity atmosphere, astronauts were suspended sideways by straps and then walked along a tilted wall.

## How did Apollo astronauts get off the Moon?

The astronauts used Eagle’s ascent stage to lift off from the lunar surface and rejoin Collins in the command module. They jettisoned Eagle before they performed the maneuvers that propelled Columbia out of the last of its 30 lunar orbits onto a trajectory back to Earth.

## Why do astronauts float on the way to the Moon?

If 90 percent of Earth’s gravity reaches the space station, then why do astronauts float there? The answer is because they are in free fall. In a vacuum, gravity causes all objects to fall at the same rate. … Since they are all falling together, the crew and objects appear to float when compared with the spacecraft.

## Could you jump off the Moon into space?

Although you can jump very high on the moon, you’ll be happy to know that there’s no need to worry about jumping all the way off into space. In fact, you’d need to be going very fast – more than 2 kilometres per second – to escape from the moon’s surface.

## What if Earth was bigger?

If Earth’s diameter were doubled to about 16,000 miles, the planet’s mass would increase eight times, and the force of gravity on the planet would be twice as strong. … If gravity were twice as strong , bodies possessing the same construction and mass as our flora and fauna would weigh twice as much and would collapse.

## Is the flag still on the Moon?

Images taken by a Nasa spacecraft show that the American flags planted in the Moon’s soil by Apollo astronauts are mostly still standing.

## How long did it take Neil Armstrong to get to the Moon?

How long did it take to reach the moon? The trio of career astronauts launched on 16 July 1969 from Kennedy Space Center in Cape Canaveral, Florida. It took them four days to travel the 55,200 miles to the surface of the moon. The shuttle landed on the moon’s surface close to midnight on 20 July.

## How long did Apollo 17 stay on the Moon?

As a result of these additions, the Apollo 17 mission had a duration of 12.6 days, and a time on the lunar surface of 75 hr with a total surface traverse distance of approximately 35 km.

## Which Apollo crashed on takeoff?

## Is Neil Armstrong alive?

Multiple departments were involved in the committee to help protect public health and agriculture. The lunar samples were vacuum-sealed and the astronauts would quarantine for 21 days, based on their knowledge of how long it took for symptoms to arise when humans are presented with an invading host, Odom said.

## Does being in space feel like falling?

Absence of gravity is known as weightlessness. It is like floating, the feeling you get when a roller coaster suddenly goes down. Astronauts on the International Space Station are in free fall all the time. … The astronauts inside it experience weightlessness, floating around in no particular direction.

## Do astronauts experience zero gravity?

Earth-orbiting astronauts are weightless for the same reasons that riders of a free-falling amusement park ride or a free-falling elevator are weightless. They are weightless because there is no external contact force pushing or pulling upon their body. In each case, gravity is the only force acting upon their body.
