Silhouetted over Earth, the International Space Station (ISS) is seen in a configuration soon to be changed, once the approaching STS-92 crew adds its important new changes. If oriented with Earth's horizon on the left, the ISS elements, from the left, are Node 1 or Unity, the functional cargo block or Zarya, the service module or Zvezda and the Progress supply ship. In a matter of days, the crew went on to add the Z1 Truss structure and a third pressurized mating adapter (PMA-3).
