4年前火星出任務！它「臨死前」最後1幕曝光 NASA不捨
洞察號與好奇號、毅力號等著陸器不同的是，前者是定點探測，而後兩者是在地表移動的火星探測車。此外，好奇號及毅力號都是核動力電池為動力，不需要陽光維持運轉，而洞察號則是太陽能電池板。
但也因為如此，積塵過多的洞察號動力逐年下滑，直至如今無法回應地球控制中心。自2022年5月起，洞察號每日動力產出僅為剛著陸時的十分之一，NASA工程師雖曾試圖指令洞察號晃動以清除沙塵，但沒有效果。
NASA聲明稿指出，「我們在過去4年中，一直將洞察號視為我們在火星的朋友和工作夥伴，所以這很難說再見，但它已經獲得當之無愧的退休生活」。
洞察號在任務期間探測到超過1300次火星震、1萬多次塵暴，以及隕石撞擊火星產生的震波和大氣波動。而它所探測火星震及內部火山活動，也與科學家過去認為火星是顆貧瘠又消沉的火星截然相反。
4 years ago Mars mission! NASA is reluctant to let go of the last scene of its "before it dies"
The difference between InSight and landers such as Curiosity and Perseverance is that the former is a fixed-point detection, while the latter two are Mars exploration rovers that move on the surface. In addition, Curiosity and Perseverance are powered by nuclear power batteries and do not require sunlight to maintain operation, while InSight is powered by solar panels.
But also because of this, the power of InSight, which has accumulated too much dust, has declined year by year, until now it is unable to respond to the Earth Control Center. Since May 2022, the daily power output of InSight will be only one-tenth of what it was when it first landed. Although NASA engineers have tried to order InSight to shake to clear the dust, it has no effect.
"We have considered InSight as our friend and work partner on Mars for the past 4 years, so it is difficult to say goodbye, but it has received a well-deserved retirement," NASA said in a statement.
During its mission, InSight detected more than 1,300 Marsquakes, more than 10,000 dust storms, and shock waves and atmospheric fluctuations from meteorite impacts on Mars. And the Martian quakes and internal volcanic activities it detected are completely contrary to what scientists used to think of Mars as a barren and depressed Mars.
