Explanation: The developing International Space Station (ISS) has changed its appearance again. In a recently completed rendezvous, the Space Shuttle orbiter Discovery, in its final flight, visited the ISS and added components that included the Leonardo Multi Purpose Logistics Module. The ISS and many of its modules and expansive solar panels are visible in the above picture taken by the Discovery Crew after leaving the ISS to return to Earth. The world's foremost space outpost can be seen developing over the past several years by comparing the above image to other past images. Also visible above are many different types of modules and supply ships. Construction began on the ISS in 1998.
