NASA: Observing Earth from Space




 Today, September 18, 12:30 AM
Google+ Hangout On Air
Join us for a live Google+ Hangout on observing the Earth while in orbit and the importance of Earth science observations from space.
 Without correction this is published to inform to the world
The astronauts living aboard the International Space Station get a unique view of planet Earth. In a single 90-minute orbit, they can see weather systems like hurricanes, man-made developments like cities and geological phenomena like volcanoes. Of all the planets NASA has explored, none yet have matched the dynamic complexity of our own Earth.

Luckily for us here on the ground, astronauts like Rick Mastracchio and Koichi Wakata have documented and shared their views from the orbiting laboratory 250 miles above the Earth. Both Mastracchio and Wakata tweeted during their 188 days in orbit, sharing photos of auroras, islands, lakes, bridges, glaciers, cities, deserts, mountains, clouds, and more. Photos like theirs give us a new perspective on our planet.

A fleet of NASA satellites also monitor the Earth’s vital signs every day. One example is the joint US-Japan Global Precipitation Measurement (GPM) mission, which launched while Mastracchio and Wakata were living on ISS. The astronauts briefed President Obama on GPM in April, describing it as “a groundbreaking satellite that is changing how we measure rain and snowfall from space.”

Mastracchio and Wakata will be joined by Eric Holthaus, a meteorologist who writes about weather and climate for Slate’s Future Tense blog, and Gail Skofronick Jackson, a GPM scientist at NASA’s Goddard Space Flight Center.
