FAA eliminates a stupid licensing requirement imposed when it “streamlined” its launch licensing regulations

9:18 am

We’re from the government and we’re here to help! The Federal Aviation Administration (FAA) announced last week that it will stop demanding rocket companies redo a flight safety analysis that have already been done by the rocket’s spaceports, a new bit of red tape that was apparently added when the agency introduced its Part 450 “streamlined” licensing regulations in 2021.

The FAA announced Dec. 13 that it will accept flight safety analyses performed by federal launch ranges in California, Florida and Virginia in applications for launch licenses under regulations known as Part 450. That decision means that companies will no longer have to perform similar analyses specifically for the FAA as part of the licensing process. Launch companies had complained of the duplication of work needed to carry out FAA analyses in addition to those required by the ranges they were launching from.

The FAA’s own bureaucracy had recognized the stupidity of this requirement (as well as many others) in July 2023 report [pdf], but the agency’s management did nothing. Apparently the political appointees who ran the agency during the Biden administration either liked this red tape — slowing American business — or were too dense to take action.

Trump’s election victory has now obviously forced some action. Not only has the agency suddenly recognized this particular problem, one week after Trump’s victory it announced the formation of an independent committee of industry and academia to review, once again, its Part 450 regulations.

It seems this committee is largely a Potemkin Village to make the Trump leadership think the agency is doing something. Instead, the FAA should do what it did last week, and adopt the many recommendations of the July 2023 report, now. The committee can then move forward cleaning up Part 450 in other areas instead of simply repeating that past work.

Boeing to take more than a decade to refit two 747s for Air Force One

7:30 pm

Utter incompetence: According to recent news reports, Boeing will not be able to deliver the two 747s it is refitting to be the president’s Air Force One fleet until 2029, even though it signed a $3.9 billion contract to do so in 2018.

The delay is startling given that Boeing isn’t building the planes from scratch. During Trump’s first term, Boeing started to overhaul two 747s that were built for a Russian airline that never took the jets.

This is more than absurd, it is obscene. Boeing is handed two flightworthy 747s and almost $4 billion, and it can’t refit the two planes in less than a decade? It seems one of the first things Trump should do once he returns to office next month is cancel this contract entirely, demand a refund from Boeing, and simply convert his present fleet of “Trump Force One” airplanes that he has been using since 2020 for use as president. Cheaper, faster, and certainly a wiser use of taxpayer money.

As for Boeing, this story illustrates once again how far this company has fallen. Remember, it was Boeing that conceived, designed, and built the 747. Moreover, its 747 has been used for decades for Air Force One. For its engineers now to be incapable to refitting another two 747s for this purpose seems inconceivable, and suggests those same engineers should not be trusted on any new planes they build.

Juno spots changes on Io’s surface in just a two-month span

10:57 am

Before and after images by Juno of volcanic ring on Io
Click for original image.

New photos taken just two months apart by Juno of a region dubbed Nusk Patera on the Jupiter moon Io showed the appearance of a distinct ring that had hardly been there before.

The pictures, taken during two recent fly-bys of the moon, are above, and show the change. From the caption:

A red ring formed around Nusku Patera in the two months between the spacecraft’s 58th flyby on Feb. 3, 2024, and its 60th on April 9, 2024. The ring obscures some nearby features like Creidne Patera. This ring, 683 miles (1,100 kilometers) wide is likely from a Pele-type plume rich in sulfur. Similar transient red rings were observed by NASA’s Galileo mission around Grian Patera and Surt and were associated with intense but short-lived thermal “outburst” eruptions.

In other words, sulfur from eruption from the central vent/caldera was flung into the sky enough that when it eventually settled back down it landed in a ring about 340 miles away from the center.

Other data from Juno, also released this week here and here, detected fresh lava flows at another volcanic region of Io dubbed, Zal Patera.

SpaceX launches more Starlink satellites

9:39 pm

SpaceX today successfully launched 22 Starlink satellites, 13 of which were for its direct-to-cell constellation. The Falcon 9 rocket lifted off from Vandenberg in California, its first stage completing its ninth flight by landing successfully on a drone ship in the Pacific.

According to a tweet by SpaceX at the end of October, only five more launches were necessary to complete the first version of its direct-to-cell Starlink constellation. Today’s launch meets that criteria. Since the FCC has approved the constellation’s license, this means T-Mobile can start offering the service to customers, filling in all dead spots worldwide.

What makes this launch even more unique is that for the first time in quite awhile there was a four-day-plus gap between SpaceX launches. The company has been launching so often that it has been rare for more than two days to pass this year without a launch.

The leaders in the 2024 launch race:

129 SpaceX
60 China
16 Russia
13 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 148 to 92, while SpaceX by itself leads the entire world, including American companies, 129 to 111.

The video replays her singing the same thing three times. There is a good reason, as she almost appears to have begun singing as a lark, and the acoustics of the church astonish her. The repeats help bring out this amazing quality.

I always open the Christmas-Hannukah holiday season with this truly glorious piece of music, as it speaks to both religions. And it is one magnificent song, sung here magnificently.

Perseverance reaches top of Jezero Crater rim

1:41 pm

The view west out of Jezero Crater
Click for high resolution panorama. For original images, go here and here.

Overview map
Click for interactive map.

After spending more than three and a half years exploring the floor of Jezero Crater, the rover Perseverance has finally reached the top of the crater’s western rim, and is about to begin exploring the mountainous and potentially rich mining region to the west.

The panorama above, created from two pictures taken by Perseverance’s right navigation camera on December 11, 2024 (here and here), has been cropped, reduced, enhanced, and annotated to post here. It looks west into that mountainous region, with the yellow lines on the overview map to the right indicating the approximate view. The blue dot on that map marks Perseverance’s present position, on top of Lookout Hill, the name the rover team has given to that spot on the rim.

The low resolution of the region beyond the grey strip is unexplained. For some reason the rover team has not yet updated the interactive map showing Perseverance’s travels with the many high resolution pictures that Mars Reconnaissance Orbiter (MRO) has taken of this region, in anticipation of Perseverance’s travels there. I expect however this will change shortly.

Witch Hazel Hill is the first target beyond the rim, where there is an outcrop 330-feet-high with many layers. The rover will then head downhill and south to check out a spot that the scientists believe might show features existing from before Jezero Crater was formed. The rover will then head back up to the rim further south to look at an outcrop of blocks that might actually be ejecta from another much larger Martian impact.

These blocks may represent ancient bedrock broken up during the Isidis impact, a planet-altering event that likely excavated deep into the Martian crust as it created an impact basin some 745 miles (1,200 kilometers) wide, 3.9 billion years in the past.

Jezero sits on the northwestern rim of Isidis.

Curiosity begins to round the corner out of Gediz Vallis

Curiosity looks ahead
Click for original image.

According to an update yesterday from the rover team, the Mars rover Curiosity has finally begun to round the corner of the northern nose of the long ridge dubbed Texoli that forms the western wall of Gediz Vallis, the slot canyon that the rover has been exploring since August 2022.

The picture to the right, reduced, sharpened, and annotated to post here, was taken on December 10, 2024 and shows the view looking west. The red dotted line indicates the planned route. As the rocky ground indicates, travel forward in the near term will be interesting. As noted in the update:

While we want to head southwest, we had to divert a bit to the north (right of the image shown) to avoid some big blocks and high tilt. The path is very constrained in order to avoid driving over some smaller pointy rocks, scraping wheels along the sides of blocks, or steering into the side of blocks that might cause the steering to fail. And we also needed to worry about our end-of-drive heading to be sure the antenna will be clear to talk to Earth for the next plan. We ended up relying on the onboard behavior to help us optimize everything by implementing a really interesting and curvy 24-meter path (about 79 feet).

Rocket startup Stoke Space completes static fire test of first stage engine

10:02 am

Stoke's Nova rocket
Stoke’s Nova rocket

The rocket startup Stoke Space revealed yesterday that it has completed a static fire test of the first stage engine it will use on its Nova rocket, shown in the graphic to the right.

The test, which was not the first for this engine, proved out several new technologies.

Stoke Space called the test significant for several reasons. It’s the first hotfire of the company’s Block 2 (flight layout) stage 1 engine, and this engine architecture — called full-flow staged combustion (FFSC) — is considered particularly challenging. Only two entities in the world — Stoke and SpaceX — have successfully developed FFSC engines. … Stoke’s stage 1 engine is a liquified natural gas/liquid oxygen engine capable of producing 100,000 pounds of thrust. The duration of the test was not revealed.

It was the first time Stoke has tested on its new vertical test stand in Moses Lake. The company’s testing philosophy is that you must “test like you fly,” and it believes vertical testing is key to engine development.

Nor is the first stage engine the only technological innovation. Nova’s second stage uses a radical design whereby the engine releases its thrust through a ring of small nozzles on the outside perimeter of the stage, rather than a single central nozzle. This design is what the company hopes will allow it to return that upper stage intact for reuse.

The four year old company has raised $100 million in investment capital, but has also faced environmental red tape from the Space Force for its launch facility at Cape Canaveral. It had previously targeted 2025 for the first test flights of Nova, but that schedule appears unlikely because of this red tape.

SpaceX requests special election to make Starbase at Boca Chica a city

9:41 am

In a letter [pdf] sent yesterday to a local judge, SpaceX requested that a special election be held in Cameron County on whether its Starbase facilities in Boca Chica should be incorporated as a city.

To continue growing the workforce necessary to rapidly develop and manufacture Starship, we need the ability to grow Starbase as a community. That is why we are requesting that Cameron County call an election to enable the incorporation of Starbase as the newest city in the Rio Grande Valley.

Incorporating Starbase will streamline the processes required to build the amenities necessary to make the area a world class place to live—for the hundreds already calling it home, as well as for prospective workers eager to help build humanity’s future in space. As you know, through agreements with the County, SpaceX currently performs several civil functions around Starbase due to its remote location, including management of the roads, utilities, and the provision of schooling and medical care for the residents. Incorporation would move the management of some of these functions to a more appropriate public body.

The letter went on to list the many other things SpaceX is already doing to benefit the area, including many of the environmental requirements imposed on it by the FAA and Fish & Wildlife.

At this moment there has been no response from the judge or Cameron County. I suspect there will be no objection, and this vote will take place in the near future. I also expect it will pass, because SpaceX employees now make up almost the entire population of Boca Chica.

Head of FAA resigns

1:32 pm

You could leave now for all I care: Mike Whitaker, who has been director of the Federal Aviation Administration (FAA) under the Biden administration and who has apparently been the main source of that agency’s increased red tape that has almost destroyed the new rocket industry that had been emerging during the first Trump administration, announced today that he is stepping down next month.

Mike Whitaker announced his pending resignation in a message to employees of the FAA, which regulates airlines and aircraft manufacturers and manages the nation’s airspace. He became the agency’s administrator in October 2023.

Since then, the challenges confronting Whitaker have included a surge in close calls between planes, a need for stricter oversight of Boeing. antiquated equipment and a shortage of air traffic controllers at a time of high consumer demand for air travel.

The article at the link is from PBS, so of course it makes this federal bureaucrat appear a hero. Instead, he was a disaster for America’s space industry, forcing unnecessary delays in SpaceX’s Starship/Superheavy program, imposing new regulations that claimed to streamline the launch licensing process but did exactly the opposite, and generally forcing FAA regulators to take a fearful attitude to any new technology, so much so that it became almost impossible for that new technology to launch.

As for the aviation industry, Whitaker’s term did little to change things. For example, he did nothing to shut down the DEI programs at major airline and airplane companies that were causing the hiring of unqualified people.

All I can say is good riddance.

Land of knobs

Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on July 17, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled merely as a “terrain sample,” it was likely taken not as part of any specific research project, but to fill a gap in the camera’s schedule in order to maintain its proper temperature.

When the camera team does this, they try to pick interesting targets. In this case, they targeted this 400-foot-high pointy-topped hill. The smoothness of its slopes suggest this hill is made up largely of packed dust, possibly a hardened former dune. This hypothesis seems strengthened by the erosion on the eastern slopes, which appears to be areas where that packed sand has worn or blow away.

Think of sandstone in the American southwest. It is made of sand that has hardened into rock, but wind and water and friction can easily break it back into dust particles, resulting often in the spectacular and weird geological shapes that make the southwest so enticing.

But is this sand?

Io’s volcanoes get their lava from separate magma chambers, not a global underground ocean of magma

11:11 am

Io's interior as presently theorized
Click for original animation.

Using data collected from Juno’s multiple fly-bys of the Jupiter moon Io, scientists now hypothesize that the moon does not have a global underground ocean of magma, feeding its many volcanoes, but that instead each volcano is fed its lava from a separate magma chamber.

The graphic to the right illustrates the present conclusion. You can read the paper here [pdf]. From the press release:

The Juno team compared Doppler data from their two flybys with observations from the agency’s previous missions to the Jovian system and from ground telescopes. They found tidal deformation consistent with Io not having a shallow global magma ocean.

“Juno’s discovery that tidal forces do not always create global magma oceans does more than prompt us to rethink what we know about Io’s interior,” said lead author Ryan Park, a Juno co-investigator and supervisor of the Solar System Dynamics Group at JPL. “It has implications for our understanding of other moons, such as Enceladus and Europa, and even exoplanets and super-Earths. Our new findings provide an opportunity to rethink what we know about planetary formation and evolution.” [emphasis mine]

The highlighted words indicate the significance of this data. It possibly suggests that the underground oceans of water that have been theorized for these other moons — where life could possibly exist — might be mistaken. Instead, they might have smaller pockets of water, similar to Io’s many magma chambers.

Everything here however is uncertain, including these new conclusions about Io. We just don’t have enough data from any of these moons to make any definitive conclusions.

ESA continues to dither about building a heavy lift rocket

10:47 am

In what almost appears to be a clown show, the European Space Agency (ESA) has three times issued and then retracted and then reissued a request for proposals for studying possible designs to possibly build a heavy lift rocket to both replace Ariane-6 as well as compete with SpaceX’s Starship/Superheavy.

ESA published an initial call for its European 60T LEO Reusable Launch System Pathfinder Study initiative on 20 November. The call was, however, deleted later that day. On 3 December, a second version of the call was published and then removed, once again, on the same day. On 10 December, ESA published a third iteration of the call, with this one being the first to remain published overnight.

The second version put more emphasis on “time and cost efficiency.” The third version added details noting the limitations of Ariane-6 (its cost, limited payload capacity, and non-re-usability).

When ESA issued the second version, I noted its lack of urgency. “This is ‘call’ for a ‘study’ to ‘explore’ the ‘options’ for development. Hell will freeze over before ESA starts construction.” The new version doesn’t change this in the slightest. It only recognizes more fully the bad decisions that ESA made in 2015 when it approved the expendable design of Ariane-6, making it too expense then to compete with SpaceX’s Falcon 9.

Chinese citizen arrested for flying drone illegally over Vandenberg

10:29 am

Yinpiao Zhou, a Chinese citizen in America on a legal immigrant visa, has been arrested for flying a drone illegally over Vandenberg Air Force Base.

Nearly a mile above Vandenberg Space Force Base in Santa Barbara County, a hacked drone soared through restricted airspace for roughly an hour. The lightweight drone photographed sensitive areas of the military facility on Nov. 30, including a complex used by SpaceX, according to federal investigators. The drone then descended back to the ground, where the pilot and another man waited at a nearby park.

Before either could leave however, four security officers from Vandenberg showed up. Initially Zhou lied about what he was doing, hiding the drone under his jacket. At one point however the officers spotted the drone, forcing Zhou to admit the truth as well as delete the footage on the drone.

Neither Zhou or the second man, who remains unidentified, were arrested at that time. Zhou was arrested on December 9, 2024 at San Francisco International Airport, just before he was to board a flight back to China. He is charged with flying a drone illegally out of his line of sight and in a no-fly zone, and remains in custody.

It appears this was an intended spying operation by China or one of its pseudo-companies, attempting to steal more information about SpaceX’s technology in order to copy it. Why Zhou and that other man were not arrested immediately is unclear.

Ispace signs agreement with lunar mining startup

10:15 am

Landing sites on Moon

The Japanese lunar lander startup Ispace has now signed an agreement with a lunar mining startup dubbed Magna Petra to transport the latter company’s helium-3 mining equipment to the Moon.

In a memo of understanding, ispace and Magna Petra have agreed to collaborate to utilize the moon’s resources for economic benefits to life on Earth, the companies announced Tuesday, Dec. 10. Through “non-destructive, sustainable harvesting,” according to a joint statement, Magna Petra plans to one day extract “commercial quantities” of helium-3 isotopes from regolith on the lunar surface for delivery and distribution back on Earth, where the resource is facing an extreme supply shortage.

Ispace meanwhile still has to prove it can put a lander on the Moon. Its first attempt, Hakuto-R1, almost succeeded, but crashed in April 2023 when its software thought it was just above the ground and shut down its engines when it was still three miles high. The company’s second attempt, dubbed Resilience and carrying a rover dubbed Tenacious, is scheduled for launch in January 2025. The landing site is shown on the map to the right, within Mare Frigoris in the northern part of the Moon’s nearside hemisphere.

A satellite startup in Oman signs on to China’s lunar base partnership

10:03 am

Middle East, showing Oman's proposed spaceport

Oman Lens, a satellite startup in Oman, has signed an agreement with China to participate in its International Lunar Research Station (ILRS) lunar base project.

This follows Oman’s first suborbital launch, which according to Oman’s state-run press lifted off from its Duqm proposed spaceport facility and reached space. None of this however has been confirmed, though government officials said they hope to do three more suborbital test flights in the next year.

The Duqm spaceport hopes to be fully operational for orbital flights by 2026. Besides China, Oman has also been in negotiations with various American rocket startup companies, though no deals have been announced, mostly because of the State Department’s ITAR restrictions protecting American technology from hostile foreign theft. Oman is not necessarily considered a friendly country.

It appears Oman decided to make a deal with China when it couldn’t make one with the U.S.

As for China’s ILRS project — it formed in competition with the U.S. Artemis Accords — it has now signed thirteen countries and about a dozen academic institutions and international companies. It claims it hopes to get fifty countries on board, but that number likely includes such institutions, not nations.

Click for original image.

The demo maneuvering spacecraft ADRAS-J, built by the Japanese orbital tug startup Astroscale, has successfully maneuvered to within 50 feet of the abandoned rocket stage that the company hopes to grab and de-orbit on a later mission.

When ADRAS-J was 50 meters behind the upper stage the spacecraft reduced the gap in a straight-line approach then maneuvered to approximately 15 meters below the Payload Attach Fitting (PAF) — the planned capture point for the follow-on ADRAS-J2 mission — aligning the spacecraft’s relative speed, distance, and attitude. ADRAS-J successfully maintained this position until an autonomous abort was triggered by the onboard collision avoidance system due to an unexpected relative attitude anomaly with the upper stage. The spacecraft safely maneuvered away from the debris as designed before reaching the CIP. Astroscale Japan is currently investigating the cause of the abort.

Engineers will have to understand that the cause of that abort prior to launching ADRAS-J2, the mission that will grab the stage and de-orbit it.

A review of the last half century of major ice calving events in Antarctica detects no trend

11:58 am

47-year trend of large iceberg calving events in Antarctica
Click for original image.

The uncertainty of science: A review by scientists of major ice calving events in Antarctica that have occurred in the last 47 years has detected absolutely no trend either up or down, despite decades of predictions that human caused global warming would cause huge sections of the icecap to break off and catastrophically change the Earth’s climate.

The graph to the right comes from figure 4 of the paper, and illustrates the lack of trend. Note how the actual observations, the blue dots, show no increase in large calving events. From the abstract:

We use 47 years of iceberg size from satellite observations. Our analysis reveals no upward trend in the surface area of the largest annual iceberg over this time frame. This finding suggests that extreme calving events such as the recent 2017 Larsen C iceberg, A68, are statistically unexceptional and that extreme calving events are not necessarily a consequence of climate change.

The researchers of course genuflect to human-caused global warming in their conclusion by stating that the shrinkage predicted in the Antarctic ice cap (but not yet seen in any significant amount) could instead be occurring due to an increase in small calving events.

The lack of an upward trend in annual maximum iceberg area could be attributed to an overall increase in the number of smaller calving events, which may inhibit the development of extremely large calving events. As such, small calving events pose the greatest threat to the current stability of Antarctic ice shelves.

Since there is no detailed or reliable data of the number of smaller calving events, this hypothesis is entirely made up, and carries no weight. It is simply a fantasy created to maintain the fiction of global warming. A more open-minded look at these results would say that the larger events provide an excellent guide to the overall trend, and that the icecap simply isn’t shrinking as predicted.

Part 2 of 2: De-emphasize a fast Moon landing and build a real American space industry instead

10:41 am

In part one yesterday of this two-part essay, I described the likelihood that Jared Isaacman, Trump’s appointment to be NASA’s next administrator, will push to cancel NASA’s Space Launch System (SLS) rocket and its Orion capsule, deeming them too expensive, too unsafe, and too cumbersome to use for any viable effort to colonize the solar system.

I then described how the Artemis lunar landings could still be done, more or less as planned, by replacing SLS with Starship/Superheavy, and Orion with Starship. Such a change would entail some delay, but it could be done.

This plan however I think is short-sighted. The Artemis lunar landings as proposed are really nothing more than another Apollo-like plant-the-flag-on-the-Moon stunt. As designed they do little to establish a permanent sustainable human presence on the Moon or elsewhere in the solar system.

Isaacman however has another option that can create a permanent sustainable American presence in space, and that option is staring us all in the face.

And now for something entire different

Capitalism in space: I think Isaacman should shift the gears of Artemis entirely, and put a manned Moon landing on the back burner. Let China do its one or two lunar landing stunts, comparable to Apollo but incapable of doing much else.

Land-locked Zimbabwe wants a spaceport, and is asking the Russians to help build it

9:47 am

According to the head of Zimbabwe’s space agency, Painos Gweme, the land-locked African country hopes to build its own spaceport and launch its own rocket sometime in the next ten years, and is in negotiations the Russians for aid.

In an interview published on Tuesday, Gweme told TASS that his country has begun negotiations with Russia’s national spaceflight corporation, Roscosmos, about the planned projects, including connecting Zimbabwe to Moscow’s cosmonaut training system. “We expect that with the assistance of our Russian colleagues, we will be able to launch our own rocket into space within the next 10 years,” he said, according to the news agency.

“We hope that our first rocket will be launched from our own cosmodrome. We have already begun working on plans, selecting a location whose natural conditions would be best suited for creating a launch complex,” Gweme added.

Any launches that take place from Zimbabwe will have to cross either South Africa or Mozambique, so expect their to be some objections from those quarters.

I also suspect that if Russia is considering this, it is doing so with the intention of building that Zimbabwe spaceport for its own uses. Zimbabwe certainly doesn’t have the capability to do this, even in ten years. Because of Russia’s invasion of the Ukraine in 2022 it was banned from its launch site in French Guiana, operated in partnership with the European Space Agency. Roscosmos might be hunting for another international site to give it more options, as well as some good international publicity.

Lucy about to do close fly-by of Earth in order to slingshot it towards the orbit of Jupiter

9:33 am

Lucy's future route through the solar system
Lucy’s route to the asteroids. Click for original image.

On December 12, 2024 the asteroid probe Lucy will do a very close fly-by of Earth, dipping to only 220 miles of the ground and thus giving it the velocity to fly through asteroid belt between Mars and Jupiter and on to the Trojan asteroids that orbit with Jupiter.

During the gravity assist, the Lucy spacecraft, from Earth’s perspective, will approach from the direction of the Sun. This means that observers on Earth will not be able to see Lucy approaching, as it will be lost in the Sun’s glare. Lucy’s trajectory will bring the spacecraft very close to the Earth, even lower in altitude than the International Space Station. To ensure the safety of the spacecraft as it passes through this region full of Earth-orbiting satellites and debris, NASA has procedures to anticipate and avoid potential collisions. If needed, the spacecraft will execute a small trajectory correction maneuver 12 hours before closest approach to alter the time of closest approach by 1 or 2 seconds — enough to avoid a potential collision.

Shortly after sunset, keen observers in the Hawaiian Islands may be able to catch a glimpse of Lucy as the spacecraft approaches Earth before it passes into Earth’s shadow at 6:14 p.m. HST. Lucy will speed over the continental U.S. in darkness, travelling over 33,000 miles per hour (14.8 kilometers per second), and emerge from Earth’s shadow 20 minutes later at 11:34 p.m. EST. At that time, Lucy may be visible to observers with a telescope in the western regions of Africa and the eastern regions of South America as sunlight reflects off the spacecraft’s large solar panels (observers in the eastern United States will be looking at the much dimmer “back” side of the solar panels, making Lucy harder to see

No imagery is planned for this flyby in order to protect the spacecraft’s science instruments.

After the fly-by, Lucy’s next target will be the main belt asteroid Donaldjohanson in April 2025. Its arrival in Jupiter orbit will follow in 2027.
