Farewell, Blue Ghost! Private moon lander goes dark to end record-breaking commercial lunar mission
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.

Cyberpunk 2 associate game director admits CD Projekt Red "are sometimes slower" than players would like, and yeah, I'd already made peace with the fact we'll be waiting on this sequel for years
When you buy through links on our articles, Future and its syndication partners may earn a commission. Cyberpunk 2077 quest design director Paweł Sasko admits that "we are sometimes slower [than] you would like" as the delayed Patch 2.3 finally goes live. The new update for Cyberpunk, which adds new vehicles, gameplay options, bug fixes and quality of life improvements, was originally planned for release on June 26, 2025, but wound up being pushed back to July 17 when developer CD Projekt Red announced on social media that "we'll need some more time to make sure we're happy with it". With Patch 2.3 now finally going live, Sasko, who's also associate game director on the upcoming Cyberpunk 2077 sequel, tells fans to "enjoy" the update as he says: "Everything we do, is for you. We are sometimes slower [than] you would like to [sic], but we always have the best of our community and our game in heart." Despite the apologetic tone, it seems as though the community has been perfectly happy to wait for the end result. Early initial reactions to Patch 2.3 seem positive, and even the original announcement that it was being rescheduled back in June was largely met with understanding and patience by the fanbase. That might be due to the fact that it's generally understood that game development is taking longer and longer with every passing year, an issue that's by no means exclusive to CDPR. As graphics and technology get more complicated and the scale of many projects increases, the time and resources needed to create these games is only getting greater, not helped by some studios jumping the gun and announcing projects way in advance of their actual release. To hammer that point home, The Elder Scrolls 6 was announced back in 2018, and there's no reason to think it'll be out any time soon. But of course, that community patience could always be because CDPR specifically has learned its lesson about rushed development. Cyberpunk's launch in 2020 was notorious for its poor performance and missing features, particularly on consoles, as well as brutal levels of crunch being reported in the months leading up to the game's release date. Consequently, the fanbase seems happy for the company to pace itself and its workload, considering the ugly consequences of what happened when it didn't. I fully agree with them on that score. Still, Sasko's comment is a reminder that good things come to those who wait, and a momentary glimpse into the priorities of a CD Projekt Red that appears to have learned its lesson. I guess with current industry trends and timescales in mind, I look forward to playing the Cyberpunk sequel sometime around the actual year 2077. Despite a rough start, Cyberpunk 2077 would eventually make it up to our list of the best RPGs! Check out what else made the list – and what took the first place spot.

Start your week smart: NASA's future, Starvation in Gaza, Stabbing incident, Extreme heat risk, Swimming showdown
If you've been suffering through the high temperatures that have scorched much of the country this summer, you know the toll it can take on your body, leaving you dizzy, dehydrated and, in some severe cases, at risk of death. But there's another lesser-known impact of extreme heat — and it might surprise you. Here's what else you need to know to start your week smart. 🔦 Few US government agencies have navigated as much turmoil in recent months as NASA. With the impending loss of thousands of jobs looming, this week saw the release of a scathing letter from nearly 300 current and former NASA employees and the abrupt resignation of the director of the Goddard Space Flight Center. Scientists and agency workers criticized budget cuts, grant cancellations and a 'culture of organizational silence.' They also raised concerns about suggested changes to a system of safety checks and balances. President Donald Trump appointed US Secretary of Transportation Sean Duffy as interim NASA administrator to replace Janet Petro, a longtime agency employee. That came after the nomination of tech billionaire Jared Isaacman to lead NASA was rescinded. Some scientists are criticizing the agency as the Trump administration tries to dismantle the NASA Goddard Institute for Space Studies, one of the country's top climate labs. Employees are working remotely after their New York City office was shut down. Back in March, NASA astronauts Suni Williams and Butch Wilmore returned to Earth after gaining international attention as their short trip to space stretched into a saga lasting more than nine months. It's an example of how quickly things can go sideways. Meanwhile, leaks have plagued the International Space Station. 📸 In photos: Astronaut Don Pettit captures unique views of the cosmos.

The International Monetary Fund will release its July 2025 World Economic Outlook Update. This publication provides analyses and projections of the global economy. In an update in April, the IMF said forecasts for global growth had been revised markedly down compared with its January update, reflecting effective tariff rates at levels not seen in a century. The Federal Reserve is set to conclude its fifth interest rate meeting since President Donald Trump returned to office in January, with policymakers expected to hold rates steady once again. The decision is likely to draw sharp criticism from Trump, who has repeatedly clashed with Fed Chair Jerome Powell over the bank's refusal to cut rates. Tension between the two was evident last week during a tour of the Fed's $2.5 billion headquarters renovation, a project the Trump administration has used to intensify pressure on Powell. 📹 Watch this awkward exchange between Powell and the president. The National Transportation Safety Board will begin a three-day public hearing to investigate the January 29 mid-air collision between a regional jet and an Army helicopter over the Potomac River near Washington, DC, that killed 67 people.

Scientists may have solved a chemistry mystery about Jupiter's ocean moon Europa
When you buy through links on our articles, Future and its syndication partners may earn a commission. A long-standing mystery about the presence of hydrogen peroxide (H2O2) on Jupiter's icy ocean moon Europa may be closer to being solved. Hydrogen peroxide forms as a byproduct when energetic particles break apart water molecules, leading to the recombination of OH radicals — highly reactive molecules with unpaired electrons. H2O2 was first observed on Europa by the Galileo Near Infrared Mapping Spectrometer, a scientific instrument aboard NASA's Galileo Jupiter orbiter that was designed to study the composition and surface features of the gas giant's moons and atmosphere using infrared light. Later, the James Webb Space Telescope (JWST) noticed elevated levels of hydrogen peroxide in unexpected areas on the Jovian satellite. Lab studies predicted that higher concentrations of hydrogen peroxide would be found in Europa's colder polar regions — but JWST observations showed the opposite, detecting higher levels in the moon's warmer equatorial regions. These areas, known as chaos terrains, are marked by broken blocks of surface ice that appear to have shifted, drifted and refrozen. "Europa's peroxide distribution does not follow the temperature dependence predicted for pure water ice," wrote the team in their paper. Lab studies consistently show that colder ice has more H2O2, while warmer ice has less. In a new study, scientists report that they have noticed higher levels of carbon dioxide (CO2) in the chaos terrains alongside elevated levels of H2O2. This is probably the result of CO2 escaping Europa's subsurface ocean through cracks in the ice, the researchers say. The team therefore wondered if the presence of CO2 might be changing the ice's chemistry. "Could the presence of CO2 drive the enhanced peroxide production in Europa's chaos regions, signaling a surface composition more conducive to the formation of this radiolytic oxidant?" they wrote in their paper. "Supporting this hypothesis are preliminary experiments on irradiated H2O-CO2 ice mixtures that show increased H2O2 yields compared to pure water ice." To find a definitive answer, they "simulated the surface environment of Europa inside a vacuum chamber by depositing water ice mixed with CO2," Bereket Mamo, a graduate student at The University of Texas at San Antonio and a contractor with the Southwest Research Institute, said in a statement. "We then irradiated this ice mixture with energetic electrons to see how the peroxide production changed." The experiment confirmed what the team had suspected: Even small amounts of CO2 in water ice can greatly boost hydrogen peroxide production at temperatures similar to those on Europa's surface, helping to explain the unexpected JWST observations. This occurs because CO2 molecules behave as "molecular scavengers," grabbing hold of any stray electrons produced when radiation hits the water ice. By capturing these electrons, the CO2 helps protect hydrogen peroxide from being broken apart by further impacts or reactions.

"In fact, an entire NASA mission, the Europa Clipper, is en route to the Jovian system right now to explore the icy moon and help us understand Europa's habitability. "Our experiments provide clues to better understand JWST Europa observations and serve as a prelude to upcoming close-range investigations by Europa Clipper and ESA's [the European Space Agency] JUICE spacecraft," Cartwright added.
