Look how far we’ve come!

Orbiter length: 122 feet

diameter

A straight line passing through the center of a circle or sphere.

8,000 Miles

13,000 Kilometers

diameter

2,100 Miles or 3,500 Kilometers

Our moon is 1/4th the diameter of the Earth.

circumference

The size of something as given by the distance around it.

25,000 Miles

40,000 Kilometers

apogee

The point in the orbit of a heavenly body at which it is farthest from the earth.

252,000 Miles or 405,000 Kilometers

perigee

The point in the orbit of a heavenly body at which it is nearest to the earth.

224,000 Miles or 360,000 Kilometers

mean

The average value of a set of numbers.

240,000 Miles or 386,000 Kilometers

Using two objects to represent the Earth and moon, let’s estimate how far away the moon is from the Earth.

estimate

An approximate judgment or calculation.

Using circumference:

240,000 miles/25,000 miles = 9 ½

384,500 km/40,000 km = 9 ½

How long would it take to go to the moon?

Let’s take a car. We’ll even go faster than the speed limit (since there are no signs in space). Let’s say, 100 mph.

That means it will take 2,400 hours = 100 days!

That’s too long! Let’s take a jet instead.

A commercial airliner goes about 600 mph.

Now we’ll arrive in 400 hours = 16 ½ days!

The Saturn V rocket took us to the moon. With this rocket the trip took only 3 days!

To date, the Saturn-V is still the largest rocket ever built and flown. It was 363 ft tall.

Humans took their first trip to the moon in 1968. All we did then is fly around it.

• In July of 1969 Neil Armstrong and Buzz Aldrin were the first humans to walk on the moon.
• The last time we went to the moon was in 1972.
1972??? Are you joking?
• The median household income was \$9,697.
• Cost of a first class stamp was 8 cents.
• The pocket calculator was invented by Texas Instruments.
• The VW Beetle was the biggest selling car.
• M*A*S*H and the Waltons premiered on TV.

Using two objects to represent the Earth and the shuttle orbiter, let’s estimate how far away the orbiter is from the Earth.

estimate

An approximate judgment or calculation.

Approximately how large will the International Space Station be when it’s completed?

1 Field

2 Fields

3 Fields

2 Fields!

Where will we go next?

This looks like a lovely sunset…but it isn’t from Earth!

What about a trip to the “Grand Canyon” of Mars? Valles Marineris is about 2500 miles long and up to 4 miles deep.

You should plan when to leave for this trip. At its closest, Mars is still tens of millions of miles away from Earth. Still, the decreased distance during "closest approach" allows for fuel-conserving flights to Mars every 26 months and a good view of Mars once or twice every 15 to 17 years for Earth-bound sky watchers.

Distance from Earth: Minimum

35 million miles (56,000,000 km) Maximum

250 million miles (399,000,000 km).

Using two objects to represent the Earth and Mars, let’s estimate how far away Mars is from the Earth.

estimate

An approximate judgment or calculation.

How long would it take to go to Mars?

Let’s take a car. We’ll even go faster than the speed limit (since there are no signs in space). Let’s say, 100 mph.

That means it will take 560,000 hours = 23,333 days = 64 years!

That’s too long! Let’s take a jet instead.

A commercial airliner goes about 600 mph.

Now we’ll arrive in 58,333 hours = 2,430 days = over 6 years!

Perhaps the new Crew Exploration Vehicle currently being developed will take us to Mars. With current technology, it will take an average of 7 months to travel one way to Mars.
