太阳系天体使深空探索更省油！今天的视频显示，2026年5月，在火星引力的帮助下，普赛克飞船以最小的燃料消耗加速并改变了它的轨道。火星绕太阳的平均轨道速度接近87,000公里/小时（54,000英里/小时）。它的轨道运动和重力使火星能够拉着赛姬一起前进，从而增加了航天器的速度。自1959年的月球3号任务以来，重力辅助就被用于让宇宙飞船（旅行者号，卡西尼号）比单独使用燃料到达更远的地方。这一帮助帮助了普赛克飞船前往普赛克小行星的旅程，它将于2029年到达。在经过火星时，宇宙飞船测试了分析小行星组成和磁场的仪器。这是第一次对一颗被认为主要由金属构成的小行星进行探测，而不是岩石或冰。金属是行星的重要组成部分。寻找黑暗的天空，仰望这个八月，见证不受月球影响的英仙座流星雨！

Solar System bodies make deep space exploration more fuel efficient! Today’s video shows the Psyche spacecraft gaining speed and changing its trajectory with minimal fuel spent due to a gravity assist from Mars in May 2026. Mars has an average orbital speed of almost 87,000 km/h (54,000 mph) around the Sun. Its orbital motion and its gravity allowed Mars to pull Psyche along with it, increasing the spacecraft’s speed. Gravity assists have been used since 1959’s Luna 3 mission to allow for spacecraft (the Voyagers, Cassini) to reach farther than they could with fuel alone. This assist helped the Psyche spacecraft on its journey to the Psyche asteroid, which it will reach in 2029. While passing Mars, the spacecraft tested instruments that will analyze the asteroid’s composition and magnetic field. This is the first mission to an asteroid thought to be largely made of metal, an essential building block for planets, rather than rock or ice. Find dark skies and look up this August to witness the Perseid meteor shower uninhibited by the Moon!
