        NASA Stops Trying to Repair Lucy's Troublesome Solar Array


According to NASA, the circular solar array is 98% extended and is powering the Lucy spacecraft, which is now traveling to Jupiter's Trojan asteroids, adequately.
NASA is pausing efforts to deploy a fussy solar array on the Lucy spacecraft because they believe Lucy is too cold and that efforts will be more successful when Lucy is closer to the Sun in December 2024.

One of the two 24-foot-wide (7-meter-wide) solar arrays on the spacecraft, which powers Lucy, failed to fully unfold after launch in October 2021 and remained in an unlatched state. Despite prior attempts by NASA to fully deploy the array, the agency stated in a blog post that the Lucy team will be postponing attempts due to the spacecraft's extreme cold.

However, NASA isn't worried about the situation and estimated in a blog post that the array is 98% deployed and will be strong enough to last the balance of Lucy's 12-year voyage to the mysterious Trojan asteroids that orbit Jupiter both in front of and behind it.
Erin Morton, a NASA communication officer, stated in a post last week that "ground-based tests revealed that the deployment attempts were most successful while the spacecraft was warmer, closer to the Sun." "The team does not expect further deployment attempts to be beneficial under the current circumstances," the statement reads. "The spacecraft is currently 123 million miles (197 million kilometers) from the Sun (1.3 times farther from the Sun than the Earth) and moving away at 20,000 mph (35,000 km/hr).

Soon after the mission's launch, NASA observed problems with the solar array and concluded that they were caused by a loss of tension in the lanyard that was used to unfold the circular array. Lucy is currently hurling away from the Sun and growing steadily colder, but she will make a gravity assist landing on Earth in December 2024. The Lucy crew is currently hoping that the spacecraft will be warm enough to make another attempt.

While Lucy continues its mission to examine Jupiter's Trojan asteroid clusters, the team behind it will be gathering data on the misbehaving solar array to observe how it performs in its slightly disabled state.

SpaceX completes 300th Falcon booster landing during Starlink mission

  S paceX completed a Falcon 9 launch, highlighted by the company’s 300th booster landing to date. The Starlink 6-53 mission also marked the 30th orbital launch from Florida in 2024. Liftoff from Space Launch Complex 40 at Cape Canaveral Space Force Station happened at 6:17 p.m. EDT (2217 UTC). The 45th Weather Squadron forecast a greater than 95 percent chance of favorable weather at liftoff. The Falcon 9 first-stage booster supporting this mission, tail number B1078, made its ninth launch on this flight. It previously launched NASA’s Crew-6 mission to the International Space Station, USSF-124, and five Starlink flights. About eight and a half minutes after liftoff, B1078 landed on the SpaceX droneship, ‘Just Read the Instructions.’ In addition to this being the 300th Falcon booster landing overall, it was the 79th landing for JRTI and the 233rd droneship landing to date. The 23 Starlink satellites onboard this mission add to the 5,851 currently in orbit, according to astronomer a...

NASA’s Newest Spaceplane: Dream Chaser Tenacity Arrives at Kennedy Space Center

  SOURCE - https://www.space.com/dream-chaser-space-plane-tenacity-tour.html Sierra Space’s Dream Chaser Tenacity, part of NASA’s initiative to enhance commercial resupply missions to the International Space Station, arrived at Kennedy Space Center for its first mission. After rigorous pre-launch testing, it is scheduled to deliver 7,800 pounds of cargo using a ULA Vulcan rocket. As part of NASA’s efforts to expand commercial resupply in low Earth orbit, Sierra Space’s uncrewed spaceplane arrived at NASA’s Kennedy Space Center in Florida ahead of its first flight to the International Space Station (ISS). The Dream Chaser spaceplane, named Tenacity, arrived at Kennedy on May 18 inside a climate-controlled transportation container from NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, and joined its companion Shooting Star cargo module, which arrived on May 11. Pre-Launch Testing and Preparation Before arriving at Kennedy, the spaceplane and its cargo module underwent vibration ...
