6 Mayıs’ta başlayıp 16 Haziran’a kadar devam edecek,[{” attribute=””>NASA’s Lucy mission team carried out a multi-stage effort intended to further deploy the spacecraft’s unlatched solar array.Throughout the meticulous process, the team commanded the spacecraft to operate the array’s deployment motor for limited periods of time, allowing them to closely monitor the spacecraft’s response.
As a consequence of this work, the mission succeeded in further deploying the array and now estimates that the solar array is between 353 degrees and 357 degrees open (out of 360 total degrees for a fully deployed array). Furthermore, the array is under considerably more tension, giving it substantially more stabilization. Because of this, the mission team is increasingly optimistic the solar array will successfully meet the mission’s requirements in its current tensioned and stabilized state.
For now, further deployment attempts will be paused as the Lucy spacecraft enters a planned period of limited communications. Due to thermal constraints caused by the relative positions of the Earth, spacecraft, and Sun, the spacecraft will be unable to communicate with the Earth via its high-gain antenna for several months. Throughout this period, the spacecraft will use its low-gain antenna remain in contact with Lucy’s ground team.
After its Earth gravity assist maneuver on October 16, the spacecraft will emerge from this partial communications blackout. At that time, the mission team will have more opportunities to attempt further deployment efforts if deemed necessary.
On June 21, the spacecraft successfully carried out a trajectory correction maneuver, which is the second in a series of maneuvers to prepare the spacecraft for its Earth flyby.
16 Ekim 2021’de fırlatılan Lucy, güneş sisteminin oluşumundan kalan küçük bedenlerden oluşan bir popülasyon olan Truva asteroitlerini keşfedecek ilk uzay görevi olacak. Güneş etrafındaki yörüngelerinde önderlik ederler veya takip ederler. Jüpiter ve bize Dünya’daki organik maddelerin kökenleri hakkında bilgi verebilir. Lucy uçacak ve altı farklı Truva asteroidi üzerinde uzaktan algılama gerçekleştirecek ve yüzey jeolojisini, yüzey rengini ve kompozisyonunu, asteroit içlerini/toplu özelliklerini araştıracak ve Truva atlarının uydularını ve halkalarını gözlemleyecektir.
