+ CRISM Research
The Compact Reconnaissance Imaging Spectrometer
for Mars (CRISM) is a NASA sponsored instrument currently onboard the
Mars Reconnaissance Orbiter (MRO) which is in orbit around
CRISM opened its cover in September of 2006 and
has begun taking images. Check out the first images here!
is an infrared spectrometer that measures light from 0.4 microns to 4
microns. This region of the electromagnetic spectrum extends from what
we can see with our eyes (the visible) to what is commonly termed the
mid infra-red. Just like infrared sensors here on Earth, CRISM can
reveal patterns our eyes are not sensitive to, because molecules and
minerals react differently to infrared light.
CRISM does not, however, extend its greatest
sensitivity to the "thermal infrared" region where it may be able to
sense heat. This region has been covered at Mars by the Thermal
Emission Spectrometer (TES). TES was sensitive to heat, and in
particular, how heat was emitted from Martian materials, however
because Mars is so cold, it is very challenging to interpret the
information from TES. CRISM, by looking at reflected light from the
Sun, at over 500 wavelengths (for many so called "hyperspectral"
observations) will reveal at very fine spatial scale (down to about 18m
per pixel) between minerals on the surface.
I'm excited about what CRISM is going to reveal on
Mars, if you'd like to learn more, you can contact me or you can go to
a couple of related websites which are listed below. Periodically I'll
update this page with my latest work on CRISM data, I've included a few
teasers here already.
