SMART 1: Pythagoras Crater
Explanation:
Stark shadows show off the central peaks and terraced walls
of 120 kilometer wide
Pythagoras Crater in this
mosaic
of images from ESA's SMART-1 spacecraft.
Characteristic of large, complex
impact craters on the Moon,
the central uplift was produced by a rebound of
the suddenly molten lunar crust during the violent
impact event.
Propelled by an efficient
ion engine, the innovative SMART-1
spacecraft entered lunar orbit in November
last year after a leisurely 13 month journey from planet Earth.
Now
viewing
the lunar surface from an altitude of 1,000 to 5,000 kilometers
SMART-1
(Small Missions for Advanced Research in Technology -1)
will spiral closer to
the Moon later this month.
