In an attempt to begin to quantify the Martian meteor year, we have simulated meteor shower detection in the Martian and terrestrial atmospheres. Assuming a meteoroid stream flux, size distribution and velocity based on current knowledge of Earth streams as well as the proximity of certain comets' orbits to that of Mars, we numerically integrate meteoroid ablation in model Martian and terrestrial atmospheres. Using the same baseline detector characteristics (limiting magnitude, sky coverage) we have generated detection statistics for the two planets. We present results for four showers, including strong annual activity and velocity extremes from Halley-type comets at both planets. We show that for high speed showers similar detection rates can be expected at both planets but for showers with low approach velocities very low mass indices would be required to produce detection rates greater than 10 per hour at Mars. Finally we will comment on what these findings mean in terms of monitoring the Martian atmosphere for meteor activity.
