Hangout With Explorers of Land, Sea, and Sky on Earth Day

The National Geographic flag represents the three classic environments of exploration: green for the sea, brown for the land, and blue for the sky.


#OurEarth: Innovation in Exploration

This year National Geographic celebrates its 125th anniversary and a long legacy of exploration, conservation, and research. Every hour of every day, National Geographic explorers take to land, sea, and sky (each frontier represented by a colored band on National Geographic’s historic flag) trying to uncover, understand, or help care for the world around us.

Since our very earliest expeditions, new technological developments have allowed us to go places and make discoveries not possible before, and to share them with the rest of the world in new and exciting ways. Now, this Earth Day, National Geographic is teaming up with NASA and Catlin Seaview Survey to bring you to the watery depths of the Great Barrier Reef, the soaring heights above the polar ice caps, and the vast red-soil plains of Oklahoma’s lightning zone.

You’ll get an insider’s view into cutting-edge technology from a specialized fleet of detection aircraft to high-tech storm tracking equipment to deep-water robots–innovations that allow us not only to explore the Earth, but also to change it for the better.

Send in your questions for the explorers and they may be asked on air. You may even be invited to join the Hangout and ask your questions live. Submit your questions by…

  • Uploading a video question to YouTube with #OurEarth (submissions due by April 17th)
  • Posting a question on Google+ or Twitter with #OurEarth or
  • Commenting directly on this blog post

Follow National Geographic on Google+ or tune in right here on this blog post to watch the Google+ Hangout Monday, April 22th at 12 p.m. ET (5 p.m. UTC).

    I love storms, exceptionally large ones. Tornadoes fascinate me and I was wondering what is a good way to spot one without the technology?

    What’s the best way for an untrained enthusiast to get involved in science? I’m deeply interested in geology and meteorology, but unfortunately can’t really swing college. Time, money, and life happening. Is there still a way for me to get involved and learn more?

    Hi Lauren – great idea for a Google Hangout! Did you consider attempting to include astronauts from NASA? NASA is widely involved in social media events!

    Day by day water level is increasing slowly and slowly due to the melting of glaciers, and its said its due to global warming. So we should take some measures to save the world, how it can be done in this modern and high technology world when all the country is trying in getting or making nuclear to make the country powerful. Can we save our future generations.

    why do humans have the desire to take over the world and destroy so many things in the process of being selfish and getting what they want?

    If a cloud with mega volts of charges is going to discharge to ground through a single lightning rod, do you think the process of discharging will be different if it discharge to multiple lightning rod? Why and how is the difference? If there’s no difference, why?
