The Lucy spacecraft, launched on Oct. 16, 2021, is now over 30 million miles, or 48 million kilometers, from Earth and continues to operate safely in “outbound cruise” mode. Besides a solar array that didn’t latch after deployment — an issue the mission team is working to resolve— all spacecraft systems are normal. The arrays are producing ample energy, charging the spacecraft’s battery as expected under normal operating conditions.
The current plan supports a latch attempt in the late April timeframe; however, the team is continuing to study the possibility of leaving the array as is. In the meantime, in the lab, they are testing a dual motor solar array deployment using both the primary and backup motor. The testing aims to determine if engaging both motors at the same time applies enough force to complete the deployment and latch the solar array.
In addition to the solar array activity, the team continues to run routine operations on the spacecraft. The next activity is calibrating guidance, navigation & control hardware to ensure pointing accuracy of the spacecraft.
On January 5, Lucy completed a test to look at the dynamics of the spacecraft in order to characterize the solar array.
GREENBELT, Md. (NASA PR) — NASA plans to conduct additional ground tests on an engineering model of the Lucy solar array motor and lanyard prior to potentially attempting full deployment of one of the probe’s solar arrays.
GREENBELT, Md. (NASA PR) — Following a successful launch on Oct. 16, 2021, analysis of NASA’s Lucy spacecraft systems show the spacecraft is operating well and is stable. Lucy’s two solar arrays have deployed, and both are producing power and the battery is charging. While one of the arrays has latched, indications are that the second array may not be fully latched. All other subsystems are normal. In the current spacecraft attitude, Lucy can continue to operate with no threat to its health and safety. The team is analyzing spacecraft data to understand the situation and determine next steps to achieve full deployment of the solar array.
Editor’s Note: The main question appears to be how the situation might affect thruster firings on the spacecraft, which is due to explore one main-belt asteroid and seven Trojan asteroids during its 12-year mission.
LITTLETON, Colo. (NASA PR) — With less than a year to launch, NASA’s Lucy mission’s third and final scientific instrument has been integrated onto the spacecraft.
The spacecraft, which will be the first to explore the Trojan asteroids — a population of small bodies that share an orbit with Jupiter — is in the final stages of the assembly process. Just five months ago, at the beginning of the Assembly, Testing and Launch operations (ATLO) process, the components of the Lucy spacecraft were being built all over the country. Today, a nearly assembled spacecraft sits in the high bay in Lockheed Martin Space in Littleton, Colorado.
GREENBELT, Md. (NASA PR) — NASA’s Lucy mission is one step closer to launch as L’TES, the Lucy Thermal Emission Spectrometer, has been successfully integrated on to the spacecraft.
“Having two of the three instruments integrated onto the spacecraft is an exciting milestone,” said Donya Douglas-Bradshaw, Lucy project manager from NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The L’TES team is to be commended for their true dedication and determination.”
WASHINGTON (NASA PR) — NASA will broadcast coverage of a first for the agency as its Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission attempts to collect a sample of asteroid Bennu on Tuesday, Oct. 20, at 6:12 p.m. EDT.
Live coverage of the spacecraft’s descent to the asteroid’s surface for its “Touch-And-Go,” or TAG, maneuver, which will be managed by Lockheed Martin Space near Denver, will begin at 5 p.m. on NASA Television and the agency’s website.
SAN ANTONIO, Texas, August 28, 2020 (NASA PR) — NASA has approved the final development stage of the Southwest Research Institute-led Lucy mission to explore the Trojan asteroids in preparation for its October 2021 launch.
SAN ANTONIO, Texas (SwRI PR) — NASA’s Lucy mission, led by Southwest Research Institute (SwRI), has achieved an important milestone by passing its System Integration Review and clearing the way for spacecraft assembly.
This NASA Discovery Program class mission will be the first to explore Jupiter’s Trojan asteroids, ancient small bodies that share an orbit with Jupiter and hold important insights to understanding the early solar system.
The Government Accountability Office (GAO) released its latest assessment of NASA’s major projects at the end of April. It found that NASA’s performance on its major projects continued to deteriorate on cost and schedule. (Full Report)
Below are key excerpts from the report that provide an overview of where NASA stands on its major projects. Although GAO did not analyze the Artemis program to return astronauts to the moon, the watchdog warned the Trump Administration’s decision to move the landing date up from 2028 to 2024 will put more pressure on the space agency.
“Looking ahead, NASA will continue to face significant cost and schedule risks as it undertakes complex efforts to return to the moon under an aggressive time frame,” the report stated.
NASA’s Lucy mission to explore a group of Trojan asteroids orbiting in tandem with Jupiter remains on cost and schedule for a November 2021 launch, according to a new assessment from the Government Accountability Office (GAO).
Determined to land astronauts on the moon in time for the 2024 presidential election, the Trump Administration has proposed boosting NASA’s budget by 12 percent, an increase that includes $3.37 billion program for a human lander.
The $25.2 billion plan for fiscal year 2021 is $2.69 billion above the current spending level. More than half the amount, $12.95 billion, would be spent on human space operations in Earth orbit and preparing for missions to the moon.
How the proposal will fair in Congress is unclear. To boost Artemis spending, the Administration has proposed a number of cuts that Congress has rejected in previous Trump budgets. Those reductions include:
SAN ANTONIO, January 9, 2020 (SwRI PR) — Less than two years before launch, scientists associated with NASA’s Lucy mission, led by Southwest Research Institute, have discovered an additional small asteroid that will be visited by the Lucy spacecraft. Set to launch in 2021, its 12-year journey of almost 4 billion miles will explore the Trojan asteroids, a population of ancient small bodies that share an orbit with Jupiter.
LITTLETON, Colo. (NASA PR — NASA’s Lucy mission successfully completed its Critical Design Review on Oct. 18.
During this review, Lucy team members presented the completed mission design, demonstrating that the team has met all the technical challenges of the mission and is ready to begin building hardware. After the review completion, NASA’s independent review board provided a green light for proceeding into the fabrication/manufacturing stage of the mission.
SpaceNews reports that SpaceX has dropped it protest of NASA’s decision to award a launch contract to United Launch Alliance (ULA) for its Lucy asteroid mission.
SpaceX did not disclose the reason it withdrew the protest, and a company spokesperson declined to comment when contacted by SpaceNews about the withdrawal. According to GAO’s website, SpaceX filed a separate protest over the same contract March 25, which was also withdrawn April 4. The company also declined to comment on the difference between the two protests.
When it filed the protest in February, SpaceX argued it could perform the same mission for a “dramatically lower” price than the $148.3 million value of the ULA contract. “We believe the decision to pay vastly more to Boeing and Lockheed for the same mission was therefore not in the best interest of the agency or the American taxpayers,” a company spokesperson said then. ULA is a joint venture of Boeing and Lockheed Martin.
ULA said that it was selected in part because it offered schedule assurance for the mission. Lucy must launch during a 20-day window in October 2021 in order to carry out its complex trajectory of flybys of six Trojan asteroids and one in the main asteroid belt. Should the launch miss that window, the mission cannot be flown as currently planned.
