Astronaut Ron Garan, known on Twitter as @Astro_Ron, has been sharing his unique view with tens of thousands of space fans.
Garan has been photographing Earth, Space Shuttle Atlantis, and his team's spacewalks from his home aboard the International Space Station, where he currently resides as a member of Expedition 27.
In 2009, NASA placed an order for 11 D3S digital SLR cameras with F-S NIKKOR 14-24mm f/2.8G ED lenses to be used for photographic documentation in space, according to Nikon. NASA has reportedly used Nikon equipment since the early 1970s, and, to date, has taken more than 700,000 photographs using Nikon equipment.
This most recent image from Garan's Twitter feed is a view from the ISS showing a lone iceberg floating in the ocean in the lower right corner of the image.
Over the last few weeks, many of the astronaut's pictures have focused on Space Shuttle Atlantis as it made its final visit to the space station. @Astro_Ron tweeted this picture of Atlantis over Sandy Point in the Bahamas in mid-July, calling it "My new favorite Shuttle px."
As Atlantis ends the final mission of NASA's space shuttle program, @Astro_Ron captured this parting image and tweeted: "The last view #FromSpace of Shuttle #Atlantis taken today (7/19/11) from Sergei's #ISS bedroom window".
