火星将短暂“失联”

Core Viewpoint - On January 9, Mars will experience a conjunction with the Sun, leading to a temporary "loss of contact" with Earth due to the alignment of the three celestial bodies [1][4]. Group 1: Astronomical Event - The conjunction of Mars and the Sun occurs when Mars and the Sun have the same geocentric ecliptic longitude, resulting in a very small angular distance between them [4]. - This event happens approximately every 26 months, determined by the relative orbital periods of Earth and Mars [4]. Group 2: Communication Impact - During the conjunction, Mars will be approximately 359.5 million kilometers away from Earth, equivalent to about 2.403 astronomical units [1]. - Communication between Earth and Mars will be disrupted due to solar interference, as the Sun's radio signals overpower those from Mars' probes [7]. - NASA has announced that from December 29, 2025, to January 16, 2026, there will be a complete communication blackout with Mars probes [10]. Group 3: Scientific Community Response - Scientists will pause sending new commands to Mars probes during the conjunction period to avoid potential loss of instructions and disruption of missions [10]. - The "loss of contact" period is expected to last only a few weeks, described as a "space vacation" for the busy probes [10].
