Prometheus Remastered
Explanation:
What does Saturn's shepherd moon Prometheus really look like?
The
raw
images from the
robotic Cassini spacecraft's
January flyby of the small moon showed tantalizing clues on
grainy images,
but now that the
Cassini team has
digitally
remastered these images,
many more details have come out.
Pictured above, Prometheus more clearly shows its oblong shape as well as numerous
craters over its 100-kilometer length.
In the
above image, the bright part of
Prometheus is lit directly by the Sun,
while much of the dark part is
still discernible through sunlight first reflected off of
Saturn.
These new surface details, together with
the moon's
high reflectivity, can now help humanity better understand the history of
Prometheus
and
Saturn's rings.
Today, Cassini has a
planned targeted flyby of Saturn's largest moon
Titan, while on Wednesday,
Cassini is scheduled to swoop to within 600 kilometers of
Dione.
