A Martian Valley
Explanation:
This tantalizing close-up detail of a network of martian valleys
was recorded
from orbit this April by Mars Global Surveyor's camera.
Water may once have flowed here but now sand dunes stripe
the windswept valley floor.
The Mars Global Surveyor spacecraft arrived in orbit in September of 1997
and has been
exploring the red planet since.
Three other spacecraft,
Mars Climate Orbiter,
Mars Polar Lander, and
Nozomi are presently en route.
