Astronaut Rick Mastracchio (AstroRM) tweeted this image on Dec. 12 from the #ISS and wrote, “Volcano in Central America. The white lines that look like clouds are airplane contrails.” Rick is taking photos from the orbiting outpost some 240 miles up circling the Earth every 90 minutes. The International Space Station (ISS) continues the NASA tradition of Earth observation from human-tended spacecraft. Operational since November 2000, the ISS is well suited for documenting Earth features and provides an excellent stage for observing most populated areas of the world. Images coming down from the International Space Station are processed on a daily basis and include over 1.2 million images through Nov. 1, 2013.
