How did NASA navigate to the Moon?

Apollo astronauts used three navigation systems to determine the proper flight paths to the Moon and back to Earth. An optical navigation system consisted of a scanning telescope and a sextant. With these instruments the astronauts could take star sights and plot the position of their spacecraft.

How did NASA track Apollo 11?

NASA relied on the U.S. State Department to implement an extensive global network of antennas to collect radio signals from the Apollo missions, including the first moon landing, which occurred 50 years ago.

Who found the trajectory to the Moon?

Mathematician Katherine Johnson
Mathematician Katherine Johnson worked out how Apollo 11 astronauts would get to the moon by calculating the spacecraft’s trajectory. Johnson, who is now 100 years old, was featured in the movie “Hidden Figures.”

Why did NASA stop sending astronauts to the Moon?

But in 1970 future Apollo missions were cancelled. Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.

How many American astronauts have walked on the Moon?

Neil Armstrong and Edwin “Buzz” Aldrin were the first of 12 human beings who walked on the Moon. Four of America’s moonwalkers are still alive: Aldrin (Apollo 11), David Scott (Apollo 15), Charles Duke (Apollo 16) and Harrison Schmitt (Apollo 17). In all, 24 American astronauts made the trip from the Earth to the Moon between 1968 and 1972.

What was the first time we went to the Moon?

The 1968 Christmastime flight of Apollo 8 was a milestone – humans left low Earth orbit and reached the moon, circling it for almost a day. For the first time, people gazed on the moon from orbit. They found it desolate and gray, but saw nothing to prevent journeying the final 62 miles to the surface.

What did Apollo 8 astronauts see on the Moon?

Surveyor 7 undertakes the final robotic reconnaissance of the Moon’s surface prior to the Apollo landings. Apollo 8 is the first mission to take humans to the Moon. After swinging around the far side, the astronauts are greeted with a sight never seen before by human eyes: the home world appearing to rise over the lunar horizon.

How long would it take to get to the Moon?

Ask how far away the moon is and how long participants think a trip to the moon would take. (Rockets using current propulsion systems take between 2.5 and 4 days to arrive at the moon.) Tell participants that a simple model will help illustrate the unique mathematical relationship the moon has to Earth.
