NASA solved the problem of the unopened Lucy asteroid solar panel

Last year, NASA launched a Lucy spacecraft to study Jupiter's Trojan asteroids, but one of them failed to fully open and capture the solar panels, and the American agency made numerous attempts to deploy the panel and recently reported that a solution had been found, albeit not fully.

The fact that one of the solar panels could not fully open was revealed 12 hours after Lucy's launch. It was not possible to establish the cause of the failure. Since there were no cameras on the solar panels, it was difficult to determine the source of the problem. NASA experts came up with a different solution. They started Lucy's engines in an attempt to identify any abnormal vibrations resonating on his body. The engineers then collected a detailed model of one of the mechanisms responsible for releasing the solar panels of the probe. The experts concluded that the strop that opened the panel dome could be trapped in the pubic drum.

The engineers suggested two ways to solve the problem. The first suggested keeping it as it is. The panel opened not completely, but enough to generate energy. Both panels together provided 90% of the power, and the on-board batteries of the state apparatus were recharged. The second option was to draw more of the solar panel strings using the main and auxiliary motors of the lobster in the hope that the jamming mechanism would re-activate.

The risk of the second option was that the pubic design did not allow both engines to operate simultaneously. For several months, a team of NASA engineers developed and tested computer models to understand the full potential effects of this operation. They finally decided to do it. They started the two engines of the pubic at the same time seven times, thus enabling the solar panel to be more exposed and tensioned.

Unfortunately, both sides of the panel have not been opened to the end and have not been secured by a special locking mechanism. However, now the solar panel is noted in NASA.

In October, Lucy's machine is due to leave the field of Earth gravity to meet its first target for research, which it will reach in 2025.
