Space Observation & Technology - ExoMars orbiter captured images similar to those from the Hubble Space Telescope, but with lower resolution due to a smaller mirror (2.4 meters in diameter for Hubble) [2] - ExoMars camera resolution is about 340, with the glow around 3i Atlas spanning approximately two resolution elements [3] - High-rise camera on the Mars Reconnaissance Orbiter (50 cm in diameter) could provide a pixel size of 30 kilometers when 3i Atlas was closest to Mars at a distance of 30 million kilometers, but data retrieval is hindered by the NASA government shutdown [4] Image Analysis & Interpretation - A distinct stripe in the first images from NASA's Perseverance rover is likely motion blur, potentially caused by one of Mars' moons (Phobos or Demos) [6][7] - The elongated image is consistent with a long exposure (around 10 seconds) of one of Mars' moons, showing a sequence of spheres [8] Object 3i Atlas Assessment - Object 3i Atlas is estimated to have a 30-40% chance of not being a natural object due to anomalies such as its lack of a typical comet tail, its location in the plane of the planets, its proximity to Mars and Jupiter, its large size, and its extension glow towards the sun [9] - Monitoring of 3i Atlas is necessary to determine if it has a technological origin that could pose a threat to humanity [10] Policy Recommendation - A white paper has been submitted to the United Nations suggesting the creation of a committee to evaluate signatures of objects and alert against potential threats [10]
