Satellite Images That Will Change The Way You See The Earth

Removing ourselves from our surroundings often brings us closer to them. Astronauts speak of the Overview Effect, passing over Earth and seeing it only as a fragile speck in a massive solar system. The desire to protect and preserve is felt, as national boundaries evaporate and a global interdependency is realized. These satellite images are fascinating, overwhelming and thought provoking.

During my time in Ethiopia, I met many people who rely on health care outposts like the one seen in the bottom two pictures here. Through these outposts, children and families get vaccines, diagnoses, and treatment for diseases like diarrhea and pneumonia.

But most of these families, and most of their health care facilities, don’t have regular access to clean water. When I asked people about their greatest needs, almost all of them—from the Women’s Health Army volunteers to children—cited clean water first.

More than 45 million Ethiopians live without clean water. I spoke to women who walk miles every other day with heavy jerrycans to get drinking water for their families. The people I met explained how lack of clean water is a health problem, a financial problem, and a family problem.

So for the next week nerdfighteria is teaming up with water.org to raise money to build sustainable wells so that more than 4,000 people in Ethiopia can have clean water. Please join me in donating—or, if you can’t, in spreading the word. Thanks, and DFTBA.

UPDATE: Bill Gates has pledged to match the fundraiser if we hit our goal of $100,000 for Ethiopia.

Happy birthday to Konstantin Tsiolkovsky, the father of spaceflight, born on September 17, 1857 in Izhevskoye, Russia. To celebrate, let’s do some fun facts:

  • He was the son of a Polish deportee to Siberia.
  • At age ten he nearly became deaf from scarlet fever.
  • Like many pioneers of space travel, he was inspired by the science fiction of Jules Verne. (See Hermann Oberth for another Verne fan.)
  • Tsiolkovsky wrote his own sci-fi stories.
  • He built the first Russian wind tunnel in 1897.
  • In 1903 he published a rocket equation in a Russian aviation magazine. Called the Tsiolkovsky formula or Tsiolkovsky rocket equation, it described the relationships among rocket speed, the speed of the gas at exit, and the mass of the rocket and its propellant.
  • In 1929 he published his theory of multistage rockets, based on his knowledge of propulsion dynamics.
  • He was a big proponent of humanity moving out into the vastness of outer space: “Earth is the cradle of humanity, but one cannot remain in the cradle forever.”
  • Inspired in 1895 by the newly constructed Eiffel Tower in Paris, Tsiolkovsky was the first person to conceive of a space elevator.
  • During his lifetime he published approximately 90 works on space travel and related subjects, including designs for rockets with steering thrusters, multistage boosters, space stations, airlocks for exiting a spaceship, and closed-cycle biological systems to provide food and oxygen for space colonies.
  • There’s a crater named in his honor on the far side of the Moon.
  • He is often called the “father of spaceflight.” He’s also been called “the father of theoretical and applied cosmonautics.” (One has more dramatic punch than the other.)
  • Interestingly, Tsiolkovsky never built a rocket.

Today’s the day. The day you help save the internet from being ruined.

Ready? 

Yes, you are, and we’re ready to help you.

(Long story short: The FCC is about to make a critical decision as to whether or not internet service providers have to treat all traffic equally. If they choose wrong, then the internet where anyone could start a website for any reason at all, the internet that’s been so momentous, funny, weird, and surprising—that internet could cease to exist. Here’s your chance to preserve a beautiful thing.)
