We’re With You When You Fly

Did you know that “We’re With You When You Fly”? Thanks to our advancements in aeronautics, today’s aviation industry is better equipped than ever to safely and efficiently transport millions of passengers and billions of dollars worth of freight to their destinations. In fact, every U.S. Aircraft flying today and every U.S. air traffic control tower uses NASA-developed technology in some way. Here are some of our objectives in aeronautics:

Making Flight Greener

From reducing fuel emissions to making more efficient flight routes, we’re working to make flight greener. We are dedicated to improving the design of airplanes so they are more Earth friendly by using less fuel, generating less pollution and reducing noise levels far below where they are today.

Getting you safely home faster

We work with the Federal Aviation Administration to provide air traffic controllers with new tools for safely managing the expected growth in air traffic across the nation. For example, testing continues on a tool that controllers and pilots can use to find a more efficient way around bad weather, saving thousands of pounds of fuel and an average of 27 minutes flying time per tested flight. These and other NASA-developed tools help get you home faster and support a safe, efficient airspace.

Seeing Aviation’s Future

Here at NASA, we’re committed to transforming aviation through cutting edge research and development. From potential airplanes that could be the first to fly on Mars, to testing a concept of a battery-powered plane, we’re always thinking of what the future of aviation will look like.

:( all the time

straight ppl: haha they can't be gay they're space rocks lol

me: by that logic they can't be straight either

straight ppl: ...

straight ppl: I don't appreciate your tone.

i’m sorry

i love how garnet picks peridot up like she’s baby simba. the circle of life and death and love and birth continues~

I couldn't help but laugh maniacally.

im what the kids call

The Tale of Earth and it’s sister Theia.

Have you found it weird that the earth’s axis is tilted by 23.5 degrees and wondered what led to this? Wait, Where did the moon come from?

Well, Here’s what scientists have theorized.

The Giant Impact Hypothesis

Theia, a mars sized planet collided ( it glanced and thankfully did not collide head on, else it would have destroyed earth ) with the Earth around 4.553 billion years ago.

Theia’s debris gathered together around Earth to form what we now call- The Moon.

The collision between the early earth and Theia was so immense that it tilted the axis of rotation of the early earth by 23.5 degrees.

And it remains tilted so that way even today!!

Why do they believe in this hypothesis ?

Scientists have a very good reason to believe in the Giant Impact Hypothesis:

Earth’s spin and the Moon’s orbit have similar orientations.

Moon samples indicate that the Moon once had a molten surface.

The Moon has a relatively small iron core.

The Moon has a lower density than Earth.

Evidence exists of similar collisions in other star systems (that result in debris disks).

Giant collisions are consistent with the leading theories of the formation of the solar system.

The stable-isotope ratios of lunar and terrestrial rock are identical, implying a common origin

Have a good day !
