Crowdsourcing Gravity and Earth's Rotation!

SpaceMath needs your help! Earth's rotation causes a centrifugal force that makes the acceleration of gravity slightly less at the Equator than at the North and South Poles. Using a smartphone app called 'Gravity Meter', I want to see if we can detect this change by getting volunteers to make this app measurement from their geographic latitude. Here's what to do. 1) Download the iPhone app 'Gravity Meter' or its android equivalent, and follow the calibration process. 2)When the app completes calibrating, turn your phone off and restart the app. 3)Place your smartphone on a flat table and let it run for a few minutes. 4)Send the minimum value, maximum value and most frequent value (they should all be close to 9.8 meters/sec2) to me at sten.f.odenwald@nasa.gov including the city in which the measurement was made.

When I get enough measurements I will post the figure here, showing the results compared to the predicted acceleration! This will also make an excellent class project!

The Total Solar Eclipse of 2017!

On August 21, 2017 the Continental United States will witness its first total solar eclipse in the 21st Century. Visit NASA's official Eclipse 2017 website for activities and events near you. Also check out the many online resources available to make your experience memorable!

Below are some math challenge activities that will help you see the eclipse in a different light!

Here are some challenging projects for Citizen Explorers to consider!
