Observing System for PHX+TT
Phoenix
Spacecraft
The Phoenix lander carried the following instruments to the surface
of Mars: a robotic arm and camera, a surface stereo imager, a thermal
and evolved gas analyzer, a Mars descent imager, a surface properties
package, a thermal and electrical conductivity probe, and a meteorological
station. It operated from 25 May to 10 November 2008.

Surface Stereo Imager
Instrument
The Surface Stereo Imager (SSI) was the primary camera on the Phoenix
spacecraft. It was a higher resolution version of the imager used for
Mars Pathfinder and was provided by the University of Arizona in
collaboration with the Max Planck Institute for Solar System Research.

Telltale
Instrument
The Telltale provided a coarse estimate of wind speed and direction.
It was a lightweight cylinder suspended by Kevlar fibers from an arm
at the top of the meteorological mast. Wind speed was estimated from
the amount of deflection that was observed in images, while the wind
direction was provided by the deflection direction. A mirror and a
calibration cross pattern, which could be imaged simultaneously with
the Telltale, were employed to increase the accuracy of the measurement.
SSI and RAC cameras could both provide the images, though the SSI was
typically used. Telltale was designed and at constructed at Aarhus
University in Denmark.

Mars
Planet
Mars is a rocky planet, fourth in order from the sun. It has an equatorial
radius of approximately 3394 km, massive (but apparently inactive) volcanoes,
impact craters, deep canyons, a thin atmosphere, and seasonal changes. Its
atmosphere is primarily carbon dioxide with small quantities of water, both
of which condense to form caps in the polar regions. Noontime surface
temperatures near the equator occasionally rise above the freezing point of
water, making it an interesting target for spacecraft explorations seeking
signs of life beyond Earth.
