The historic mission of Firefly Aerospace's Blue Ghost lunar lander is over.
The solar-powered Blue Ghost went dark on Sunday evening (March 16) after the sun set on its lunar locale, bringing an end to a highly successful two weeks of surface operations on the moon.
"We battle-tested every system on the lander and simulated every mission scenario we could think of to get to this point," Blue Ghost Chief Engineer Will Coogan said in a Firefly statement today (March 17) that announced the end of the mission.
"But what really sets this team apart is the passion and commitment to each other," he added. "Our team may look younger and less experienced than those of many nations and companies that attempted moon landings before us, but the support we have for one another is what fuels the hard work and dedication to finding every solution that made this mission a success."
Blue Ghost's mission, which Firefly called "Ghost Riders in the Sky," was the company's first-ever lunar effort. The flight was supported by NASA's Commercial Lunar Payload Services (CLPS) program, which puts agency science gear on robotic landers to gather a wealth of cost-effective data ahead of the arrival of Artemis astronauts on the moon a few years from now.
Blue Ghost carried 10 NASA payloads, which it successfully delivered to a basaltic plain on the lunar near side called Mare Crisium ("Sea of Crises") on March 2. The successful touchdown was just the second ever by a private lunar lander, after that of Intuitive Machines' Odysseus vehicle in February 2024. Odysseus operated for seven Earth days on the lunar surface before going dark.
The mission plan called for Blue Ghost, and those science instruments, to operate for a lunar day — about two Earth weeks. And that indeed happened, Firefly said today, declaring "Ghost Riders in the Sky" 100% successful.
"After a flawless moon landing, the Firefly team immediately moved into surface operations to ensure all 10 NASA payloads could capture as much science as possible during the lunar day," Firefly CEO Jason Kim said in the same statement.
"We're incredibly proud of the demonstrations Blue Ghost enabled, from tracking GPS signals on the moon for the first time to robotically drilling deeper into the lunar surface than ever before," Kim said. "We want to extend a huge thank you to the NASA CLPS initiative and the White House administration for serving as the bedrock for this Firefly mission. It has been an honor to enable science and technology experiments that support future missions to the moon, Mars and beyond."

Blue Ghost was even able to observe the "Blood Worm Moon" total lunar eclipse of March 13-14. But, thanks to its unique vantage point, the lander saw this dramatic event as a solar eclipse, snapping a gorgeous "diamond ring" photo that Firefly shared with the world.
The lander beamed home a total of 119 gigabytes (GB) of data, including 51 GB of science information, before going dark as expected on Sunday at around 7:15 p.m. EDT (2315 GMT), according to Firefly.
Blue Ghost's final hours were productive. It "captured imagery of the lunar sunset on March 16, providing NASA with data on whether lunar dust levitates due to solar influences and creates a lunar horizon glow that was hypothesized and observed by Eugene Cernan on Apollo 17," Firefly wrote in the statement. "Following the sunset, Blue Ghost operated for 5 hours into the lunar night and continued to capture imagery that measures how dust behavior changes after sunset."
"Ghost Riders in the Sky" was part of a wave of private moon exploration. For instance, Blue Ghost launched on Jan. 15 along with another private lunar lander, Tokyo-based ispace's Resilience, which is expected to make its own touchdown attempt on June 5.
And Intuitive Machines' second lunar lander, called Athena, lifted off on Feb. 26 and landed near the moon's south pole on March 6. However, Athena, which was also flying a CLPS mission, tipped onto its side just after touchdown and was declared dead on March 7.
That exploration surge will continue in the coming years, if all goes to plan. Firefly is already looking forward to its second moon mission, a CLPS effort that's expected to launch in 2026. That flight will send Blue Ghost to the lunar far side and also place Firefly's "Elytra Dark" spacecraft in orbit around the moon.
