The Gravity Gusher

While browsing the internet the other day, I came across  information on a joint partnership between NASA and the DLR (German Aerospace Center) called GRACE that got me thinking about apples. In particular, Sir Isaac Newton and the apple!


You have probably heard the story about Newton and the apple, and how he came up with the idea of gravity when an apple fell from a tree and hit him on the head. Well, it turns out the apple didn’t actually hit him, but just the same was the spark the got him thinking. If you want the real story, you can read it here.


Okay you say, so what's the connection between this thing called GRACE and apples? Well, GRACE stands for Gravity Recovery and Climate Experiment. So gravity led to thinking of Newton and that led me to apples.

But the really cool thing that caught my attention in the first place, was an image of the earth generated by GRACE.

The GRACE mission was to accurately map variations in the Earth's gravity field and this image is part of the results.


What an image! Beautiful. I'm sure Sir Isaac Newton would have agreed. And it all started with an apple falling from a tree. Ideas are amazing things!


Think about it! Hundreds of years ago an apple fell from a tree. Sir Isaac Newton saw it and hatched the idea of gravity. Now today we have maps of the Earth's gravity field thanks to the award winning work of the GRACE project team.


And it continues forward. The work of GRACE will benefit society and the world's population into the future in many ways unknown to us today. And it all started with a falling apple and an idea. Amazing!
