1986年2月发射的SPOT-1地球遥感卫星按计划今年6月便服役到期,法国政府打算让它在轨道上继续工作到9月,然后由法国国家空间研究中心(CNES)接管,对该卫星进行为期3个月的超期实验,以检验它的寿命持续极限,因用新发射的卫星进行这些实验风险太大。 CNES的一位官员说:“我们将用过去从未用过的方法来实验SPOT-1卫星,如试验其恢复工作的方法,就是将卫星上的所有系统的功能 The SPOT-1 Earth remote sensing satellite launched in February 1986 was scheduled to expire in June this year and the French Government intends to keep it on track for work until September, followed by the CNES, The satellite carries out a three-month overdue experiment to test its continued limit of longevity, which is too risky to carry out these experiments with newly launched satellites. An officer from CNES said: "We will experiment with the SPOT-1 satellite in a way that has never been used before. To test its recovery work, we will put all the functions of the satellite
