How did NASA know that the Moon's gravity was less than that on the earth before they got there?

NASA knew the mass of the Moon before going and could calculate the pull of gravity relative to the earth. Weight is just the measurement of the strength of gravity while mass is how much material is packed into any one object. Gravity increases as the mass of an object increases so the Moon being much smaller than the earth would therefore have less gravity.

What does NASA use rockets for?
The National Aeronautics and Space Administration (NASA) uses rockets to lift payloads out of the earth's gravity well and into space.
According to NASA what is supposed to happen in the year 2027?
According to NASA, in the year 2027, the Earth's gravity will shift the asteroids orbit and cause it's trail to change considerably. This occurrence will be dependent on other unknown variables, of course.
Is there 0 gravity on the moon if so how does NASA provide video of men on the moon dropping a feather and hammer?
There is enough gravity on the moon for us to go there and explore. Any object with mass also has gravity. While the moon is smaller than the earth, it still has an immense amount of mass.
Where can one find pictures of earth satellites?
One can find pictures of earth satellites on the NASA Visible Earth online website. NASA Visible Earth is a catalog of NASA images of our home planet, earth. The website "Geology" is where one can also find pictures of earth satellites.
How long does it take NASA to get to the moon?
It depends on the launch vehicle and method of boosting to get to the Moon (Earth gravity assist, etc.), but in general it takes about 3-4 days to make the trip.
Which NASA missions studies earth's gravity?

Is gravity always acting on everything on earth?
no because at NASA i THINK IT WAS I cant remember they have a flying room where u can do somersaults in the air so that means no gravity
What is the force of gravity on Uranus' surface?
You can find various estimates for this because the number is not certain. The number I got from NASA's data is about 0.89 times the Earth's gravity.
What is the acceleration due to gravity on Saturn?
At the level where the atmospheric pressure is 1 bar, NASA estimated the acceleration due to gravity on Saturn is 1.065 that of Earth or 10.44 meters per second squared
How many moons and satellites does Mars have?
Mars has two natural satellites (moons) that have been named Phobos and Deimos. (Both are considerably smaller than Earth's moon.) As of January, 2009, there are 3 artificial satellites orbiting Mars: * Mars Odyssey (NASA - arrived October, 2001) * Mars Reconnaissance Orbiter (NASA - arrived March, 2006) * Mars Express (ESA - arrived December, 2003)
How do you experience weightlessness on earth?
You can approximate weightlessness in a swimming pool. NASA astronauts practice maneuvers under water.

What gravity is venus?
According to NASA, the answer is 8.87 m/s2. To translate that a little more, it is about 90% of the gravity here on Earth. A person who measures 100 kg when they leave home would tip the scales on the Venusian surface at 90 kg.
