星空有约丨9日合日！这期间火星将短暂“失联”

Core Viewpoint - The upcoming Mars conjunction with the Sun on January 9 will result in a temporary communication blackout between Earth and Mars due to the alignment of the three celestial bodies, causing Mars to be obscured by the Sun's brightness [1][3][6]. Group 1: Astronomical Event - Mars conjunction, known as the time when Mars and the Sun have the same geocentric longitude, occurs approximately every 26 months due to the relative orbital periods of Earth and Mars [3][4]. - During the conjunction, Mars will be approximately 359.5 million kilometers away from Earth, equivalent to about 2.403 astronomical units [1]. Group 2: Communication Impact - The communication between Earth and Mars will be disrupted as the Sun's strong radio signals interfere with the signals sent from Mars' probes, leading to a temporary "loss of contact" [6][10]. - Scientists will pause sending new commands to Mars probes around the time of the conjunction to avoid potential issues caused by solar radiation interference [10].
