Abstract
Meteor surveys on other planets, such as Mars, can be used to constrain the variation in the meteoroid flux away from Earth. Images from the Spirit rover have previously been used for one such survey. We report on the sampling and results of a new survey conducted with InSight lander images. The InSight survey used cameras with wider fields of view and faster optics than the Spirit survey and comprised 9.7 h of cumulative exposure time, compared to 2.7 h for Spirit. No meteors were identified. We determined that while the InSight survey was more sensitive to bright meteors, it was less sensitive to faint meteors due to compression-related issues. Further, we determined that the Spirit survey was substantially less sensitive than previously reported, and neither survey had sufficient sensitivity to test theoretical expectations given expected detections ≪1. We conclude with recommendations for the design of any future surveys.
期刊介绍：
Planetary and Space Science publishes original articles as well as short communications (letters). Ground-based and space-borne instrumentation and laboratory simulation of solar system processes are included. The following fields of planetary and solar system research are covered:
• Celestial mechanics, including dynamical evolution of the solar system, gravitational captures and resonances, relativistic effects, tracking and dynamics
• Cosmochemistry and origin, including all aspects of the formation and initial physical and chemical evolution of the solar system
• Terrestrial planets and satellites, including the physics of the interiors, geology and morphology of the surfaces, tectonics, mineralogy and dating
• Outer planets and satellites, including formation and evolution, remote sensing at all wavelengths and in situ measurements
• Planetary atmospheres, including formation and evolution, circulation and meteorology, boundary layers, remote sensing and laboratory simulation
• Planetary magnetospheres and ionospheres, including origin of magnetic fields, magnetospheric plasma and radiation belts, and their interaction with the sun, the solar wind and satellites
• Small bodies, dust and rings, including asteroids, comets and zodiacal light and their interaction with the solar radiation and the solar wind
• Exobiology, including origin of life, detection of planetary ecosystems and pre-biological phenomena in the solar system and laboratory simulations
• Extrasolar systems, including the detection and/or the detectability of exoplanets and planetary systems, their formation and evolution, the physical and chemical properties of the exoplanets
• History of planetary and space research
