ISO Observations of Mars
<=== abstract ===>
SCIENTIFIC ABSTRACT
We propose to make spectroscopic observations of Mars using all of the ISO
instruments. The main scientific goals are:
- To characterise the shape and variability of the Martian FIR
continuum spectrum. This will characterise large-scale seasonal
and topographic variations of the thermo-physical properies
(albedo and thermal inertia) of the surface.
- To determine the absolute FIR brightness temperature spectrum of
Mars, and its dependence on the Martian season, phase angle and
atmospheric dust content.
- To make complete spectral surveys using the SWS and LWS. This will
allow the determination of the concentrations of the most important
atmospheric species, and will establish a chemical inventory of the
atmospheric composition.
OBSERVATIONS SUMMARY
A full discussion of the scientific case is give in the CP programmes of
the LWS Solar System SAG and the Mission Scientists.
The following is a summary of the astronomical objectives of each of
the observations tabulated below. The expected S/N is typically
several hundred.
Obs. Seq. Nos. Description
------------------ -----------------------------------------
1,3,5,7,9,11,17,22 Full LWS grating scans to be made at
eight different epochs during the mission
2,4,6,8,10,12,18,23 Eight PHOT-S scans to be carried out at
the same time the LWS scans
13 One LWS full FP scan
14,15,16 These comprise one SWS full grating
scan (Priority 1)
19,20,21 A second SWS full grating scan (Priority 2)
24 CAM CVF scan 2.5-11.5 um

As recommended in the CP Proposal Instructions, the scientific case is
not included here.
The following is a breakdown of the contributions of the various
consortia (spacecraft time in seconds). Note that, since the
priorities within the Solar system CP have been set over the
programme as a whole, the nominal 40:30:30 distribution is not
precisely adhered to by each proposal individually. In this
proposal, for instance, 25% of the observations are first priority.
Nomimnal : Top 40% Second 30% Last 30%
Actual : Top 25% Second 62% Third 13% Total
LWS Team : 610 4760 1822 7102
SWS Team : 8511 3471 282 12264
THE Team : 0 14927 2692 17619
SOT Team : 0 0 0 0
Overall Total: 9121 23068 4796 36985
Note: There are special scheduling requirements for this programme:
The LWS full grating scans and PHOT-S scans are required to be taken at
different times during the mission, ideally at intervals of about two
months; however, the exact timing will depend on the observability of
Mars.
The CAM observation should be scheduled when Mars is as close as
possible to the Earth.
