LEARNING GOAL FOR TODAY: I will be able to show how a rocket can work in outer space after today's class

WORDS O' THE DAY:

Newton's 3rd Law: For every force exerted on an object, there is a separate but equal and opposite force exerted on a second object.

WORK O' THE DAY:

Rockets seem to be deceptively simple: Fuel is ignited and the rocket *should* move upward.

Why is it, then, that rockets are so difficult to construct AND maneuver.

═══════════════════════════

Before we begin, let's do a review of rocketry throughout history.

Have a conversation with your team and *suggest* when and where the first rockets were successfully constructed and flown (and for what purpose?)

 

 

Earliest Rockets: Let's take a gander at THIS

 

Oh and what about "The Rocket's Red Glare?" were those actually rockets?

Let's take a quick look/skim at THIS

═══════════════════════════

1920 - 1940 (First attempts at controlled flight)

1940 - 1945 (WWII)

1945 - 1960 (The Early Cold War)

1961 - 1975 (The Apollo Years)

1975 - 2010 (The Space Shuttle)

2010 - Present (Commercial Space Flight)

Let's get one person to take each of those topics. Please find a couple of rockets from your 'era' and post a picture on your classroom slide page HERE

Put a few of the following items on your slide too (if you can find them!)

• How far did that rocket fly?
• What kind of fuel did it use?
• Were there significant problems with that rocket?
• Interesting tidbits?

 

Here's another interesting question -- What is the most powerful machine ever created by human beings?

Ladies and gentlemen, I give you the Saturn V ("Saturn Five") rocket:

 

The Saturn V could lift 140,000 kg into "Low Earth Orbit" or it could lift 48,600 kg to the moon!

Let's work at making some observations of this image-- take a look at your handouts

How much of the Saturn V rocket was used ONLY to get out of the Earth's atmosphere?

Let's take a look...

How does that compare with SPACEX Starship?

Let's go see!

The Saturn V had 5 rocket motors

The SPACEX Starship had 33.

The engineers at SPACEX are some of the best in the business (although they are all about 12 years old, or at least they look like that to an old so-and-so like me!).

They CLEARLY designed that many more rocket engines to take advanage of some sort of something--- what might that be?

How did that work out for them on launch?

Why does NASA do this? (and has been doing that since the Apollo days)
