“It Was the Most Incredible Thing I Ever Witnessed”: New Film Details World’s First Private Astronauts—and a Life-Altering UAP Encounter

24 June 2026 at 14:20

The fascinating behind-the-scenes story of the exploits of the first team of private astronauts to cross the Kármán line is finally being told.

A newly released documentary film, “Beyond Blue Sky: The Untold Story of the First Private Astronauts,” now available on Apple TV and Amazon Prime, reveals the award-winning accomplishment and includes firsthand testimony from the pilots and engineers who made the inaugural private astronaut space flights possible.

The film also includes one of the two record-setting astronauts, U.S. Navy combat veteran Brian Binnie, sharing an unusual, life-altering experience for the first time on screen, an event that he credits for inspiring him to continue after a crushing setback almost ended his dreams of flying to space.

A Private Astronaut’s Failure and a UAP Encounter

In an email to The Debrief, documentary filmmaker Kevin Curran noted that his Emmy-nominated crew, “with a proven space pedigree,” including chronicling milestones of Blue Origin, SpaceX, Astrobotic, and NASA, was able to capture “razor’s-edge supersonic test flight footage” to reveal the story of the first team of private astronauts to join the small group of humans to have ventured into space.

Along the way, the documentary depicts the team’s successes and failures in their pursuit of reaching space for the first time—and then doing so two more times with extra ballast—to win a $10 million prize.

Although Binnie, a Princeton-educated aeronautical engineer and 20-year Navy pilot, would typically seem like the obvious choice for the award-winning space attempt, a difficult crash landing on the first rocket-powered test flight of the program had Binnie doubting whether he would get another opportunity to pilot SpaceShipOne for the remaining five test flights.

As incredible as the team’s historic accomplishments were, Curran told The Debrief that the story took an unexpected, but inspiring turn when Binnie revealed an out-of-this-world encounter that he credited with inspiring him to recover from that setback and ultimately make the historic flight.

“The rest of the documentary is pretty incredible/riveting, I think, but [Binnie’s] story makes it so topical right now with the Pentagon’s release of UAP files,” Curran told The Debrief.

“I Turned Around Expecting to See Them Behind Me”

According to Curran, his team had no idea about Binnie’s encounter when they started filming. As the ebullient filmmaker noted, the team was about six weeks into production on a film that he says “we thought would simply be an untold, feel-good story involving perseverance and redemption within the birth of private spaceflight.” Then, while the cameras rolled, Binnie made his revelation.

Although Curran notes that the pilot had previously confided in “dozens of people within the aerospace and test flight world over the years about his extreme close encounter,” this was the first time the veteran of 33 combat missions had “courageously” shared his experience on-screen.

“Like any good story, it simply became more fascinating the more we pulled on the thread,” Curran told The Debrief.

The tale began on December 17, 2003, when Binnie successfully piloted SpaceShipOne to nearly 68,000 feet on its first rocket-powered test flight, a critical early accomplishment that made him the first pilot to go supersonic in a privately funded vehicle. However, the flight ended in an extremely rough landing that damaged the craft’s landing gear, wing, and fuselage, putting Binnie’s future as one of three test pilots of SpaceShipOne in doubt.

“After the crash, the 47-year-old Binnie faced the reality that he may never fly the spaceship again on the remaining five test flights of the program,” a summary emailed to The Debrief explains.

Six days after the hard landing, Binnie was awake one morning at around 4 a.m., unable to sleep comfortably in his bed. Then, according to the astronaut’s account, he noticed that “bright lights were coming through my window blinds. I rose, opened the window blinds to find that daylight had manifested in my backyard.” The decorated Navy veteran noted that while his backyard was illuminated, everything else he looked at was dark.

The next part of Binnie’s story details the presence of around a dozen translucent, glowing “orbs” he said he could perceive within the lit area. However, the pilot recalled, the orbs did not seem bright enough to account for the inordinately bright light illuminating his backyard. During his on-screen recollection, the award-winning pilot also details the movement of the orbs, including two of them approaching him from approximately 50 feet away, passing through his bedroom window, and entering his chest.

“I turned around expecting to see them behind me, but they weren’t there,” he said.

Binnie described the pre-dawn experience as “the most incredible thing I ever witnessed.”

The Impact on Binnie and the Documentary Crew

When discussing the impact that the unusual experience had on him, Binnie told Curran’s team that he initially searched for a conventional explanation. With advanced engineering degrees and a 20-year Navy career that led him to become both a test pilot and manager of the SpaceShipOne program, he was well accustomed to evaluating unusual observations. However, after exhausting all prosaic possibilities, the trained scientist, pilot, and observer ultimately concluded that the mysterious glowing orbs represented an intelligent phenomenon that had somehow allowed him to perceive them.

“It gave me hope that I had a purpose, and that purpose was to not simply take defeat, but was to pick myself up and continue,” Binnie told the documentarian.

After what the team calls “a bizarre series of events” that offered Binnie a second chance to pilot SpaceShipOne, the newly reinvigorated aviator boarded the craft’s final flight on October 4, 2004. During the launch phase, when the pilot and craft are hauled to a high latitude by the mothership, White Knight, Binnie said he once again reflected on the apparent UAP experience, including how he felt the orbs had given him an intangible drive to complete his mission and make history.

By the time the flight was complete, winning both the Collier and Ansari XPRIZE, Curran said the accomplishment proved that a team of “renegade geniuses” could achieve a NASA-level feat for a fraction of the space agency’s typical cost. As far as the late pilot’s unusual UAP encounter, Curran credits Binnie’s courage for sharing his experience with UAPs, while also noting the effect the man’s retelling had on him and his crew.

Brian Confided in Colleagues for Years, But This is His First Filmed Account

“One thing I wish to clarify, in the event it matters, is that I believe Brian’s story,” Curran told The Debrief, while once again citing the combat veteran’s impressive credentials.

The documentarian also noted that there has been a stigma around the UAP subject for a long time, and that Binnie “was really brave to come out to me in 2020 before any of the House Oversight Committee testimonies or recent releases by the Pentagon.”

Brian confided in only a few aerospace colleagues about the experience for many years, and even learned of another astronaut with a similar experience, but the story’s inclusion in the film was the first time he shared it on record before passing away.

“I simply want to protect Brian Binnie’s memory and surviving family, as he was always kind to me, inspiring, and I’m proud to have called him a friend,” Curran concluded.

The project “is dedicated to the memory of test pilots Brian Binnie and Mike Melvill, the first two private astronauts who had the courage to fly stick-and-rudder to space,” the documentary team states.

“Thankfully, they shared their extraordinary stories on camera before they were lost forever in the Mojave sand,” the team concludes.

Missing a Night’s Sleep Has an Effect on Your Brain You May Not Believe

24 June 2026 at 13:00

Experiments exploring the effects of missing a night’s sleep on the human brain have found indications that a sleepless night actually increases connections between brain cells instead of impeding growth. However, the lack of sleep could also create brain “fatigue” and pressure, resulting in burnout.

The Forschungszentrum Jülich Institute of Neuroscience and Medicine team behind the discovery said that their findings might support the idea that sleep plays an important role in restoring the brain’s cellular balance.

Missing a Night’s Sleep Could Disrupt Cellular Balance

In a statement announcing the surprising discovery, study leader David Elmenhorst and colleagues note that scientists still are not in complete consensus about why humans and other animals need sleep. One proposal involves restoring synaptic connections between brain cells during certain stages of sleep, helping the brain maintain a form of cellular ‘homeostasis.’

For example, previous research has shown that synaptic connectivity increases during wakefulness. This increased activity also increases energy consumption, potentially resulting in problematic protein buildup. Conversely, scientists suspect that sleep helps restore baseline synaptic connections and protein levels, thereby maintaining a healthy cellular balance.

“Sleep is essential for synaptic homeostasis, a proposed mechanism whereby wake­fulness leads to synaptic potentiation, and sleep facilitates synaptic down-selection,” the research team explains in a recently published study.

Although previous studies suggest that missing a night’s sleep could disrupt this balance, the team notes that there is very little experimental data to support these conclusions.

Study Reveals Elevated Synaptic Activity After 28 Hours Awake

To explore the role of sleep in cellular homeostasis in the human brain, the researchers used an advanced brain-scanning technology called positron emission tomography (PET). According to the team’s statement, this tool can scan the human brain for signs of synaptic vesicle glycoprotein 2A (SV2A),  which they describe as a “marker” of brain synapses.

The team started by enlisting 40 study volunteers. Next, each volunteer was given a PET scan to establish baseline marker levels. After their first scan, 20 of the volunteers were told to get a normal night’s sleep. According to the study authors, the second half were assigned to “the sleep deprivation condition,” where they were told to miss a night’s sleep.

The next day, the team used the PET scan to search for telltale brain synapse markers. As hoped, the scans revealed a distinct difference between the two groups. Where the normal sleep group’s levels were within expected ranges, the synapse markers of the volunteers who had missed a night’s sleep were elevated.

A closer analysis found that once people passed 28 hours of continued wakefulness, their SV2A markers were higher “in several brain regions.” Notably, these increased markers were detected in the hippocampus, which plays an important role in memory, and in the thalamus, which is critical for information relay within the brain.

“Sleep deprivation led to significant increases in synaptic vesicle glycoprotein 2A binding in multiple brain regions, including the thalamus (+4.6%), hippocampus (+5.6%), and parietal cortex (+3.2%), whereas no changes were observed in controls,” the study authors write.

Sleep Deprivation Causes Fatigue and CHanges Neural COnnections

When discussing the study’s limitations, the authors note that the SV2A marker used is a “proxy” for connections between brain cells, not a direct measure. They also note that the observed changes after a missed night’s sleep “were relatively small.” Still, they add, the results in several regions across several study participants “suggest a biological connection between the need for sleep and the buildup of cell connections.”

“During sleep deprivation, the brain remains awake longer and continues to process stimuli and information,” they write. “Our study shows that after approximately 28.5 hours of wakefulness, a marker for synaptic density increases in several brain regions. This suggests that sleep deprivation not only causes fatigue but is also accompanied by measurable changes in neural connections.”

The study “Sleep deprivation increases levels of the synaptic density marker SV2A in the human brain” was published in PLOS Biology.

The Virtual World of Stonehenge Experience is Now Available Online for Free

23 June 2026 at 13:21

A virtual tour of the historic UK monument, called the Virtual World of Stonehenge, which allows users to visit one of the world’s most iconic historical sites, has just been released online to coincide with the annual summer solstice.

Along with capturing the entire 2022 British Museum’s Stonehenge virtual tour, the new online experience developed by researchers at the University of Reading allows users to travel back in time to witness the site at various stages of construction on their phones, PCs, or other devices without leaving the comfort of their homes.

Building the Virtual World of Stonehenge with 3D scans

According to a statement announcing the new online Virtual World of Stonehenge experience, the museum’s original ‘World of Stonehenge’ exhibition, which opened on February 17, 2022, attracted over 190,000 visitors and brought together “over 400 objects from 36 institutions across Europe.”

“The original exhibition brought together an extraordinary collection of prehistoric objects, many of which had never been displayed together before,” explained team member and study author, Professor Duncan Garrow, Professor of Archaeology at the University of Reading. However, the team noted, viewing the entire complex, interactive exhibit required in-person attendance.

To capture the experience and make it available worldwide, Professor Garrow and colleagues joined forces with researchers at the University of Southampton. They also enlisted the services of ArtasMedia, a team of “digital heritage specialists” which employed laser scans to digitally capture every inch of the exhibit. According to the team, these 3D scans of the original World of Stonehenge gallery were taken during the exhibition’s final weeks.

Taking the Online Tour Makes History “More Accessible”

Along with capturing all the original exhibit, the team said that the new online experience allows users to “go inside Stonehenge itself and watch it change through time, explore Neolithic flint mines at Grimes Graves, and discover rarely seen prehistoric objects through animation, soundscapes and interactive content.”

“Timed to release alongside the summer solstice, the new virtual version goes well beyond a simple recreation of the gallery,” they explain.

Some of the most striking objects featured in the museum exhibit and the virtual tour include a 6,000-year-old elm leaf, a bracelet woven from cow hair, and the remains of what the team called a “prehistoric feast.” When scanned with 3D lasers and combined with their historical context, the team said the lesser-known objects and their stories suddenly become “more accessible.”

“Now anyone, anywhere they are, can not only see those objects but understand the world of Stonehenge and experience how it looked and felt thousands of years ago,” Professor Darrow said. “We hope it brings prehistoric Britain to life in a completely new way.” 

Release Intentionally Timed with the Summer Solstice

When discussing the value of putting the Virtual World of Stonehenge online, Dr Neil Wilkin at the British Museum said the project has prompted him and his colleagues to consider the future of virtual museum exhibitions, “not just at the British Museum but everywhere across the world.”

Funded by UK Research and Innovation and building on AHRC-funded research led by British Museum curator Dr Neil Wilkin, in partnership with Professor Duncan Garrow at the University of Reading, the June 21st release of the online experience was timed to coincide with the summer solstice. Although some aspects of the iconic structure’s function may remain in dispute, most historians and many enthusiasts believe the site has been home to solstice celebrations for several millennia.

“The launch coincides with the summer solstice, the moment when Stonehenge’s alignment with the rising sun has drawn people to the site for thousands of years,” the team explained.

“It Was Completely Shocking to Me”: Archaeologists Discover the Earliest Monumental Egyptian Hieroglyphs Written 1,000 Years Before the Pyramids

22 June 2026 at 13:05

A joint expedition to the ancient Egyptian city of Elkab has unearthed several previously unknown ancient rock art inscriptions, including what the team believes are the earliest known monumental Egyptian hieroglyphs.

Written over 1,000 years before the Great Pyramid of Giza was constructed, these ancient Egyptian writings, discovered by archaeologists from Yale University and the Royal Museums of Art and History (Brussels), laid the foundation for the later, better-known hieroglyphic writing system.

Yale Professor John Coleman Darnell, the expedition’s leader and the co-director of the Elkab Desert Survey Project, said the newly discovered inscriptions, which were not recorded by any previous scientific expedition, include samples as far back as 4,000 BCE.

Although the team concedes that these are not the first examples of this specific style of rock art, they are the first of this ancient age and “monumental” scale, making them of great significance in the history of ancient Egyptian writing systems.

“This was not what I was expecting to find when I set out on this period of work on the expedition,” Professor Darnell said of the historic find. “It was completely shocking to me.”

Earliest Monumental Egyptian Hieroglyphs Depict Cosmological Concepts

In a Yale news story announcing the discovery, Professor Darnell noted that the newly discovered rock art site of El-Khawy preserved some of the earliest and largest signs “from the formative stages of the hieroglyphic script.” The professor added that the discovery includes “rare” evidence for how this enigmatic ancient society invented its internationally recognized ancient writing system.

The expedition, which was directed by Darnell and Dirk Huyge, was undertaken in cooperation with the Ministry of Antiquities and the Aswan and Edfu inspectorates.

After photographing the newly discovered inscription, Darnell and Alberto Urcia, a digital archaeologist and associate research scientist in the University’s Department of Near Eastern Languages and Civilizations, created a series of three-dimensional (3D) images. Darnell said the new technology allows archaeologists to record ancient sites and artworks “at a level of accuracy and detail that was absolutely impossible before.”

“It also means that we can record the site as a place, or a location, and not just as a series of inscriptions,” the professor added.

One of the more noteworthy examples of ancient monumental hieroglyphs, carved sometime between 4,000 and 3,500 BCE, depicted a herd of elephants. A closer examination also revealed that one of the elephants had an image of a smaller elephant inside of it, which Professor Darnell described as “an incredibly rare way of representing a pregnant female animal.”

A second discovery detailed by the joint expedition, which consists of four separate panels, was likely created sometime around 3,250 BCE. Written right to left, which ultimately became the dominant writing form in later Egyptian hieroglyphic languages, the panels show animal images of a bull’s head on a short pole, followed by two back-to-back saddlebill storks with a bald ‘ibis’ bird above and between them.

The research team said this arrangement of symbols is common in Egyptian representations created centuries after the newly discovered panels depicting the solar cycle. These same depictions typically include imagery of luminosity. Darnell suggested that the images may also express “the concept of royal authority over the ordered cosmos.”

“This is the First Time That Anyone Has Seen Them on Such a Massive Scale”

When discussing the importance of the new find, Professor Darnell noted the immense size of the individual tableaus and their elements. For example, each individual hieroglyph identified by the Yale-led team measures over half a meter in height. The professor also noted that the entire tableau “is about 70 centimeters (27.5 inches) in height,” whereas previously discovered signs of early Egyptian hieroglyphs were “only one or two centimeters in size.”

“This discovery isn’t new in the sense that this is the first time that anyone has seen these hieroglyphs,” Darnell explained, “this is the first time that anyone has seen them on such a massive scale.”

To offer a perspective on the discovery’s significance, the professor said a modern-world equivalent would be seeing smaller text displayed on your computer screen, “and then suddenly seeing very large ones made the same way,” only displayed up on a highway billboard.

When discussing the site’s location in the northeastern desert hinterland of Elkab, Darnell noted that it was a “very important” center in ancient Egypt, which demonstrates that the area’s budding communicative system “is not limited to the more commonly found small tokens or labels.”

The professor also said the study shows that ancient writing did not develop slowly “for bureaucratic use,” as researchers had previously believed. Instead, Darnell suggested that the discovery shows hieroglyphic-style writing “was more geographically widespread and topically diverse at the time of or shortly after its development.”

“This also suggests that there is a much more expansive use of the early writing system than is indicated from other surviving archaeological material,” the professor added.

eVTOLS Are Here: Archer Aviation Confirms ‘Midnight’ Aircraft On-Track for FAA Certification, 2028 Olympics

22 June 2026 at 12:55

Electric Vertical Take-Off and Landing (eVTOL) pioneer Archer Aviation has confirmed that it is on track to perform Team USA transport duty during the 2028 Summer Olympics in Los Angeles, California, aboard its Midnight aircraft.

In an email to The Debrief, a company spokesperson said Archer was selected as the Official Air Taxi Provider of the LA28 Olympic Games and Team USA, marking a historic first in the quest for commercial eVTOL operations before the end of the decade.

“Through this exclusive partnership, the two will look to integrate Archer’s Midnight eVTOL aircraft across theLA28 Games in a variety of ways, such as transporting VIPs, fans, and stakeholders, while electrifying vertiport take-off-and-landing hubs for key venues and providing support for emergency services and security,” a company spokesperson explained.

Archer CEO Announces ‘Progress’ Including Upcoming Midnight eVTOL Test Flight in 8 US Cities

Archer Aviation founder and CEO Adam Goldstein recently shared more specific updates about the company’s road to the Olympics and eventually government approval, noting that “we made tremendous progress towards beginning operations in the US later this year, with record FAA certification progress and our most expansive flight testing to date.”

Goldstein also highlighted the company’s recent winning applications to begin pre-certification test flights of Midnight in 8 US states later this year, including New York, Florida, and Texas. According to the CEO, those test flights are part of the eVTOL Integration Pilot Program (eIPP), “which was unlocked through the White House’s Executive Order in June last year.”

“Archer expects Midnight operations in American cities to begin this year as part of the White House’s eIPP and in preparation to serve as the Official Air Taxi Provider of the LA28 Olympic Games, in coordination with the DOT and FAA,” the CEO explained, adding that the two benchmarks “pave the way for Archer to showcase its air taxi technology in parallel with its continued work toward FAA Type Certification for Midnight.”

Six Independently Operating Engines Produce Over 1,500 Horsepower, Last 10,000 Flight Cycles

When asked about the technical aspects that have put Midnight on course to become the first commercial eVTOL air taxi provider in the U.S., the company spokesperson first noted that their aircraft are “designed and manufactured” domestically, which can shorten development timelines and improve quality control. This includes focusing the team’s research and development on what the company termed “differentiating technologies,” including the pioneering aircraft’s unique powertrain.

“Our world-class in-house team, coming with experience from Apple, Tesla, SpaceX and beyond, contribute to our efficient and certifiable electric propulsion design,” the company told The Debrief.

Some of the differentiating technologies the team said set it apart from the competition include rapid charging, long-lasting battery packs “and the capability of >1500 horsepower.” They also note that Midnight’s high-performance battery cells, patented high-voltage architecture, and gearbox are designed to operate reliably for roughly 10,000 “flight cycles” before the vehicle’s battery pack needs replacement.

“We are optimized for electric flight,” the company told The Debrief.

Due to the potential risks in premiering a new vehicle platform, with Archer Aviation telling The Debrief that “eVTOL aircraft are the first new category of aviation in more than 60 years,” the company said Midnight is built as a ‘fly-by-wire’ system, reducing the number of mechanical components that can fail. The company also said that each of Midnight’s engines operates independently “allowing for high levels of redundancy and safety.”

Although the current version of the Midnight eVTOL aircraft is flown by a human pilot, the company told The Debrief that it is “continuing to build the technology stack” required for its longer-term goal of a fully autonomous eVTOL aircraft.

Company Anticipating Final FAA Approval “in the Near Future”

With the 2028 Summer Olympics just two years away, the company said it has transitioned out of a successful Phase 3 of the FAA’s 4-phase Type Certification process, an industry first, and has “already been advancing its work in Phase 4 for some time now.”

“This is where Midnight’s compliance with FAA airworthiness requirements will be demonstrated through formal testing and analysis,” the company told The Debrief.

In his address to shareholders, Goldstein said the company’s flight test program “continued to expand this quarter.” The CEO said this expansion includes piloted VTOL and CTOL flights across its expanded fleet of test aircraft “occurring nearly every day, often multiple times a day.”

eVTOL
Archer Aviation has recently taken over operations at Hawthorne Airport with goals of creating the airport of the future.

To expedite the testing phases leading up to the 2028 Olympics, the company recently took over operations of Hawthorne Airport in Los Angeles County. Goldstein said the move will help Archer develop the local airstrip “into the airport of the future.”

“Located near LAX and several major LA sports and entertainment venues, Hawthorne Airport is expected to anchor Archer’s planned LA air taxi operations while also serving as an innovation hub for next-generation aviation technologies,” the CEO explained.

When asked how soon the company expects to fulfill the FAA’s Phase 4 requirements and gain full certification, the spokesperson told The Debrief that Archer is in the final stages of the process, “and is anticipating approval in the near future.” However, the company also added that their focus is on building a safe, high-performance aircraft, and that once they can demonstrate the safety and versatility of Midnight, “it is the FAA’s job to certify it.”

Scientists Release New Images Captured by the Lucy Spacecraft Flyby of Asteroid Donaldjohanson

22 June 2026 at 12:50


Scientists have released a series of previously unseen images of the asteroid Donaldjohanson captured by NASA’s Lucy spacecraft during an April 2025 flyby.

The team behind the photos’ release said the Lucy spacecraft, which was named for the infamous hominin fossil discovered by anthropologist Donald Johanson, captured critical details about the small main-belt asteroid’s surface features and motion that could help clarify the space rock’s origin and evolution.

The data could also inform studies of the Solar System’s formation, including how asteroids move and evolve over extended timescales.

Craters on Asteroid Donaldjohanson Confirm Its Age

According to a statement from team leader Simone Marchi and colleagues, images captured during the deep-space rendezvous revealed that the oddly shaped rock consists of two cratered ‘lobes’ connected by a comparatively smooth central “neck” section. The researchers noted that Donaldjohanson measured over 8.8 kilometers by 4.4 km by 3.1 km.

An analysis of the surface features helped the team pinpoint the asteroid’s likeliest age to a set of asteroids belonging to the Erigone family, a group that broke apart a larger “parent” body into smaller fragments. The team notes that this ancient age “implies that DJ is a fragment of a larger parent body that was destroyed in a collision about 155 million years ago.”

Phase: 34.4 deg. Image Width: 6.5 km. Image Credit: NASA/GSFC/SwRI/JHU-APL.

Although an examination of the craters helped place the asteroid’s likely age, they noted that craters less than 0.4 kilometers “have been preferentially erased.” The researchers suggest that this preferential erasure of smaller craters might have been caused by “seismic shaking” following a more recent impact event.

“DJ Rotates Slowly in a Tumbling State”

Along with surface features, the newly released images revealed the asteroid’s motion. Specifically, the team determined that Donaldjohanson has a slow, tumbling movement rather than a simple rotation.” Instead of an impact, the team suspects that the asteroid’s motion could have been produced gradually by “torques” resulting from thermal radiation.

“DJ rotates slowly in a tumbling state, likely owing to spin-down by radiative forces,” the team writes.

Phase: 50.5 deg. Image Width: 5.4 km. Image Credit: NASA/GSFC/SwRI/JHU-APL/DLR.

A spectral analysis of the rock’s cratered surface also revealed a similar composition to other Erigone family asteroids, particularly the presence of iron-bearing phyllosilicates. The team notes these phyllosilicates indicate an “aqueous evolution” on the parent body. However, they also note that the water-induced mineral alteration was likely halted “at an early stage” due to insufficient water or heat.

Next Mission Encounter Planned for 2027

Although the newly released Lucy images were captured in 2025, the team notes that the Donaldjohanson flyby mission was one leg of a larger set of 8 planned Lucy asteroid flybys, with the entire set expected to take 12 years to complete.

“Over its 12-year mission, Lucy will explore a record-breaking number of asteroids: it will fly by three in the belt of asteroids that circle the Sun between the orbits of Mars and Jupiter, and then eight Trojans, which includes five asteroid targets and the satellites of three of those,” a NASA statement explained. “Lucy also will fly by Earth three times to get a push from its gravity, making it the first spacecraft to return to the vicinity of Earth from the outer solar system.”

The study “​The Lucy flyby of asteroid (52246) Donaldjohanson:​ ​A bilobed object with a tumbling rotation” was published in Science.
