  • Figure 1

    Mission profile showing the phasing of aerobraking orbits, assessment orbits, science-phasing orbits, and circular orbits. Orbit period in hours is plotted against time and temporal events, including solar conjunction, nominal dust storm periods, Earth-Mars-sun distances, martian seasons, and arrival of Mars Surveyor '98 (MS98) (3) at Mars. The slope in the aerobraking periods corresponds to the average pressure exerted on the solar panels 0.6 N m−2 during the first aerobraking period and 0.2 N m−2 during the second and third periods. The orientation of the MGS orbit relative to the sun at noon is indicated by the times shown on the horizontal axis. MOI, Mars Orbit Insertion; S, southern; N, northern.
