According to foreign media reports, on Monday, local time, NASA announced that it had found the cause of the failure of the solar panel of the Jupiter asteroid cluster probe Lucy < p > < / P > < p > Lucy was launched on October 16, but one of the two large solar panels failed to deploy when it began to deploy as planned about an hour after launch. Each panel is more than 24 feet (about 7 meters) in diameter < p > now, the task team believes that they have determined the cause of the failure, that is, there is a problem with a rope that helps the solar panel unfold < p > NASA officials wrote in a previous statement: "preliminary tests show that the rope pulling out the solar panel may not complete the process as planned. However, it is uncertain what caused this. The mission team is conducting more tests to determine whether the situation is true and find the root cause." < / P > < p > the statement pointed out that, In addition to the data returned by the probe, the ground team is using engineering models to evaluate the situation. In addition, the mission team will not order the detector to try to repair the problem of solar panels until November 16 at the earliest < p > according to NASA's statement, except for the stuck solar panel, Lucy is working normally, and the probe is in cruise mode as planned. The statement pointed out that two of Lucy's three instruments have been started, and the third is expected to start working on November 8, us time < p > NASA engineers are still evaluating whether the failure of solar panels will force mission personnel to adjust their future plans. Lucy needs to spend a whole year in orbit close to the earth, and the energy generated by solar panels is enough to provide enough energy for it. However, at Lucy's destination, the Trojan asteroid group, the sun is much dimmer, and they orbit the sun the same distance as Jupiter < p > Lucy plans to fly over seven asteroids in its 12-year mission, plus one asteroid in the main planetary belt. No probe has visited these Trojan asteroids, which are sometimes called fossils of planetary formation. (small) < / P > < p >
