Sometimes it feels good to be part of something larger than yourself. Tomorrow on Earth Day you can do just that with nothing more than your phone.
Step outside and take a picture of yourself alone or with friends tomorrow holding your personalized ‘global selfie’ sign and then post it to social media using the hashtag #GlobalSelfie. After the pictures stream around the world on Earth Day, NASA will gather them up to create a mosaic image of Earth built entirely of our faces.
The effort is part of NASA’s Earth Right Now campaign focusing on study of the home planet from orbit. This year, five NASA Earth-observing missions are underway or planned, the most ever to launch in a single year in more than a decade:
* Global Precipitation Measurement Core Observatory – Launched in coordination with the Japan Aerospace Exploration Agency (JAXA) on Feb. 27, it will measure global rain and snow.
* Soil Moisture Active Passive satellite will track Earth’s water cycle, allowing the agency to “follow the water” from underground aquifers to the oceans to moisture and rainfall in the clouds.
* Orbiting Carbon Observatory-2 will measure carbon dioxide and study how carbon moves the atmosphere, land and ocean.
* ISS-RapidScat will launch to the space station and observe how winds behave around the globe to assist in weather forecasting and hurricane monitoring.
* Cloud-Aerosol Transport System (CATS) instrument will make critical measurements of clouds and aerosols (haze, dust, air pollutants).
Although we usually associate NASA with missions focused on outer space, the agency has been strongly involved in Earth science and studies from the unique perspective of orbiting observatories for decades.
When you snap your selfie, you can either print out the sign and include it in the photo like I did or create your own using rocks, pieces of wood or whatever’s at hand.
The Earth mosaic image and a video using the images will be put together and released in May.
I hope to see you there!
