At 24 feet (7.3 meters) throughout each, Lucy’s 2 photovoltaic panels went through preliminary implementation tests in January 2021. In this image, a specialist at Lockheed Martin Space in Denver, Colorado, examines among Lucy’s ranges throughout its very first implementation. These huge solar ranges will power the Lucy spacecraft throughout its whole 4-billion-mile, 12-year journey through area as it goes out to check out Jupiter’s evasive Trojan asteroids.

NASA’s Lucy spacecraft has actually effectively finished thermal vacuum screening of both photovoltaic panels, the last action in taking a look at these vital spacecraft parts in preparation for launch this fall. Once the Lucy spacecraft’s photovoltaic panels are connected and totally extended, they might cover a five-story structure.
Lucy, the 13th objective in NASA’s Discovery Program, needs these big photovoltaic panels as it will run further from the Sun than any previous solar-powered area objective. During its 12-year trip of the Trojan asteroids, the Lucy spacecraft will run a record-breaking 530 million miles (853 million km) from the Sun, beyond the orbit of Jupiter.
Seen here partly unfurled, the Lucy spacecraft’s huge solar ranges finished their very first implementation tests in January 2021 inside the thermal vacuum chamber at Lockheed Martin Space in Denver, Colorado. To guarantee no additional stress was put on the solar ranges throughout screening in Earth’s gravity environment, the group developed an unique mesh wire harness to support the ranges throughout implementation.

“The success of Lucy’s final solar array deployment test marked the end of a long road of development. With dedication and excellent attention to detail, the team overcame every obstacle to ready these solar panels,” stated Matt Cox, Lockheed Martin’s Lucy program supervisor, in Littleton, Colorado. “Lucy will travel farther from the Sun than any previous solar-powered Discovery-class mission, and one reason we can do that is the technology in these solar arrays.”
The solar ranges, produced by Northrop Grumman in Goleta, California, will be providing power to the spacecraft and its instruments throughout the 12-year objective. The photovoltaic panels require to provide around 500 watts, about comparable to the energy required to run a cleaning maker. Despite this fairly modest requirement, the photovoltaic panels need to be big as they require to run up until now from the Sun.
“At about one hour after the spacecraft launches, the solar panels will need to deploy flawlessly in order to assure that we have enough energy to power the spacecraft throughout the mission,” stated Principal Investigator Hal Levison of the Southwest Institute in Boulder, Colorado. “These 20 minutes will identify if the remainder of the 12 year objective will be an success. Mars landers have their 7 minutes of horror, we have this.”
Solar selection implementation tests happened in between December 2020 and February 2021 in the 29-foot-by-65-foot (8.8-meter-by-19.8-meter) thermal vacuum chamber at Lockheed Martin Space, where the spacecraft is presently going through assembly, launch, and screening operations.
Though when folded the photovoltaic panels are a simple 4 inches (10 cm) thick, when broadened each photovoltaic panel has a size of almost 24 feet (7.3 meters). What is more, the solar ranges can’t support their own weight of 170 pounds (77kg) each in Earth gravity, so an unique accuracy weight offload gadget is utilized inside the chamber for extra assistance.
“In spite of their complexity and size, the mechanical deployment of the arrays executed flawlessly, said Donya Douglas-Bradshaw, Lucy project manager from NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The ingenuity and innovation of the team is truly remarkable!”
These crucial tests bring the spacecraft one action better to introduce preparedness. The Lucy spacecraft will be delivered to NASA’s Kennedy Space Center in Florida this summer season to prepared it for launch when its window opens in the pre-dawn hours of Oct. 16, 2021.
Southwest Research Institute’s Hal Levison and Cathy Olkin are the primary private investigator and deputy primary private investigator of the Lucy objective. Goddard offers general objective management, systems engineering and security and objective guarantee. Lockheed Martin Space is developing the spacecraft. Lucy is the 13th objective in NASA’s Discovery Program. NASA’s Marshall Space Flight Center in Huntsville, Alabama, handles the Discovery Program for the firm’s Science Mission Directorate in Washington, D.C.
