Orbiting the Earth once every 92 minutes at an altitude of 250 miles, the crew members onboard the International Space Station have a unique perspective of our home planet. They no longer see borders, but they do see the signs of humans on Earth.
They see Earth’s majesty,
They see signs of humanity on the land . . .
. . . and in the ocean.
This Earth Day,
let us remember the words of the first human to fly in space and treasure the gift we have been given.
