Orbiting Astronaut Reflects Earth
Explanation: Astronaut
self-portraits
can be particularly interesting. Visible in the
above picture
, working in from the outer borders, are the edges of the reflecting helmet of a
space suit
, modules of the
International Space Station
(ISS), the
Earth
, the arms of
Expedition 15
astronaut
Clay Anderson
, and the digital camera used to snap the image.
This picture
was taken during the
shuttle orbiter Endeavour
's mission to expand the space station last August. The large
curvature of the Earth
appearing in the visor
reflection
is not the true curvature of our spherical Earth, but rather an artifact of the curve of the space helmet.
Earth's horizon appears only slightly curved
when viewed from the height of the ISS -- approximately 400 kilometers. The
next space shuttle mission
to the space station is currently expected to take place next month and includes the installation of the scientific
Columbus Laboratory
.
