Though planning for this Russian mission to the potentially dangerous asteroid Apophis has apparently been uncertain for years, according to Russian officials in mid-September the mission is still in development with a launch is now targeting the end of 2028.

[I]n April 2026, the Director of the Skobeltsyn Nuclear Physics Institute, Eduard Bryus said that his organization was working on the mission to Apophis using a “cubesat” or a similar small-class spacecraft, which could rendezvous with the asteroid. The landing and soil sampling was also under consideration, according to the scientist. Around the same time, Viktor Sadovnichiy, the influential head of the Moscow State University, MGU, which oversaw Skobeltsyn Institute, seemingly endorsed the mission, saying that the trip of a Russian spacecraft to Apophis would help predicting asteroid threat.

In September 2026, Skobeltsin NIIYaF re-confirmed that the small-class spacecraft designated MKA MGU-Apophis and its mission had been under development with the launch scheduled at the end of 2028.

I have added this mission to the list below of all the probes presently scheduled to visit Apophis when it makes its next close pass of the Earth on April 13, 2029. Based on past Russian history for the past three decades, however, we should not be surprised if this mission ends up not getting launched.

ESA finalizes contract for privately built cubesat lander as part of its Ramses mission to Apophis

path in 2029.

The European Space Agency (ESA) yesterday announced it has issued the full contract with private startup EMXYS to build its Don Quijote cubesat lander for ESA’s Ramses mission to go to the potentially dangerous asteroid Apophis when it flies by the Earth in April 2029.

EMXYS, a Spanish company, previously built a gravity-measuring instrument for the cubesat Juventas, which is flying on ESA’S Hera mission presently on its way to the binary asteroid Didymos/Dimorphos.

Francesca Ingiosi, overseeing Ramses’ CubeSats, notes: “There won’t be time for sustained human oversight: Don Quijote is going to take itself down on a completely autonomous basis, relying on feature tracking to find a safe place to land. It will be running its gravimeter and magnetometer when it flies, but we have high expectations for its scientific work on the surface.

“It will come down quite slowly, but in the ultra-low gravity of Apophis some bouncing along the surface is possible. The CubeSat is therefore designed to operate from any orientation, although the precise nature of the surface remains a question mark: there is even a small possibility that Don Quijote sinks into the ground, which would not be good!

The launch window for Ramses is in the spring 2028, so the schedule to get this cubesat built is very tight.

Private mission to Apophis gets another customer, two student-built landers

Apophis' path past the Earth in 2029

path in 2029.

The orbital tug startup Exlabs has signed up a second payload customer to fly on its private ApophisExL mission to rendezvous with the potentially dangerous asteroid Apophis when it makes its April 13, 2029 close fly-by of the Earth.

ExLabs has announced its partnership with Japan’s Chiba Institute of Technology (ChibaTech) and its Planetary Exploration Research Center (PERC) to send university-led payloads to the surface of asteroid Apophis during its rare near-Earth flyby in 2029. ApophisExL is the world’s first commercial deep-space rideshare and is supported by mission design and operations collaboration with NASA’s Jet Propulsion Laboratory (JPL) operated by Caltech.

Under the leadership of planetary scientist and PERC Director, Dr. Tomoko Arai, ChibaTech students and researchers are developing two landing payloads to be deployed on the asteroid’s surface.

An Australian satellite startup, Fleet Space Technologies, had already signed on to fly a mapping instrument on ApophisExL.

Though the press release at the link calls this private mission “a new model,” using private enterprise rather than relying on the government for doing planetary missions, it actually harks back to the way things were done in the U.S. before World War II, when the private sector did most of this pure research. In fact, as late as the 1960s there was at least one company, American Science and Engineering, doing the first X-ray astronomical observations flying suborbital rockets. It later won contracts from NASA and other agencies to help build several later orbiting X-ray telescopes.

Over time the government space agencies became dominant, so that most of this design work was either done by them or by universities, with private companies relegated to the roles of minor subcontractors.

This new model is simply an extension of the capitalism model that is taking over the entire space industry, shifting power and ownership from big, expensive, and inefficient government programs to small, cheap, and economical private missions. Those space agencies can still do missions, but they do it by buying payload space on these private missions.

Terran Orbital wins contract to build cubesat to go to Apophis with ESA’s Ramses probe

Apophis' path past the Earth in 2029
A cartoon (not to scale) showing Apophis’s
path in 2029.

The satellite company Terran Orbital, owned by Lockheed Martin, has won a contract from the European Space Agency (ESA) to build a cubesat to fly with its Ramses probe that will launch in 2028 and rendezvous with the potentially dangerous asteroid Apophis when it makes its very close fly-by of the Earth on April 13, 2029.

The CubeSat is named after Italian scientist Paolo Farinella and is backed by the Italian Space Agency. After successfully completing the Critical Design Review in January 2026, Tyvak International [a subsidiary of Terran Orbital] will begin the implementation phase, with launch currently planned for 2028.

…Operating aboard the RAMSES spacecraft, developed by OHB Italia, the Farinella CubeSat will be one of two spacecraft deployed to explore the asteroid’s subsurface using low-frequency radar. The satellite will also carry Horus, an optical instrument that acts as both a science imager and navigation camera, and Vista, a dust detector previously flown on the Milani CubeSat from ESA’s Hera mission.

Apophis is estimated to be about 1,200 feet across. When it does its fly-by in ’29 it will get within 20,000 miles of the Earth, dipping within the orbits used by geosynchronous satellites. It will then pass within 60,000 miles of the Moon. At its closest it will for a short time be visible to the naked eye.

Apophis’ orbit means that it has the potential in the next century or so to impact the Earth. This particular fly-by is significant because the Earth/Moon’s gravity will change the asteroid’s path in an unpredictable manner that could either increase or decrease that impact possibility on future fly-bys. And we won’t know until after the fly-by is complete.

OHB Italia wins $96 million contract to build Ramses probe to visit the asteroid Apophis

The European Space Agency (ESA) yesterday announced that it has awarded the aerospace company OHB Italia a $96 million contract to build Ramses probe to rendezvous with the potentially dangerous asteroid Apophis when it makes its next close fly-by of Earth in 2029.

This contract is in addition to the $75 million development contract awarded OHB Italia in 2024. According to the company’s press release here:

The launch is scheduled for April 2028, with a rendezvous with Apophis planned for February 2029, approximately two months before its close approach to Earth. The spacecraft will accompany the asteroid until August 2029, in order to observe in detail how Earth’s tidal forces modify its shape, rotation, orbit and surface characteristics.

The initiative also benefits from strong international cooperation. The Japan Aerospace Exploration Agency (JAXA), drawing on its well-established expertise in asteroid science, will contribute by providing launch service onboard an H3 rocket, the spacecraft’s solar arrays and a Thermal Infrared Imager, further reinforcing the project’s global dimension.

In addition, two cubesats will be launched with Ramses and deployed once the spacecraft reaches Apophis.

This schedule is very tight, which places great pressure on OHB, especially because European space projects are traditionally built slowly after years of planning. ESA almost never does things fast like this.

At the moment, Osiris-Apex (formerly Osiris-Rex) is the only spacecraft that is on its way to Apophis.

NASA releases images during Osiris-Apex’s fly-by of Earth in late September

Earth as seen by Osiris-Apex
Click for original image.

NASA today released photos taken by the asteroid probe Osiris-Apex (formerly Osiris-Rex) as it swung past the Earth on September 23, 2025 at a distance 2,136 miles, on its way to the asteroid Apophis.

The picture to the right, cropped, reduced, and sharpened to post here, was one of about 424 images taken by the spacecraft during the fly-by. From those, scientists compiled a movie, which you can view here. As this picture shows, South America was in view on the right side of the Earth.

Osiris-Apex, which had already completed its prime mission by returning samples from the asteroid Bennu, is scheduled to arrive at Apophis shortly after that asteroid’s close fly-by of the Earth on April 13, 2029. The Trump administration had threatened to shut it down for budget reasons, but Congress restored those funds in ending the government shut down.

At that time Apophis will zip past only 20,000 miles from Earth. There will be no chance of collision. Nor is there much chance Apophis will hit the Earth in the next two centuries. Its orbit however makes it a potentially dangerous asteroid, and that 2029 fly-by could change these calculations.

Australian satellite startup to fly an instrument on private mission to Apophis

In March 2024 the orbital tug startup Exlabs announced that it will use its orbital tug to deliver three cubesats to the asteroid Apophis when that object makes its next close fly-by of the Earth on April 13, 2029.

The California-based Exlabs has now signed its first customer for that mission. An Australian satellite startup, Fleet Space Technologies, has agreed to fly an instrument on this private commercial mission.

Under the ApophisExL mission, Fleet will provide geophysical sensing technologies for ExLabs’ mothership to collect targeted data and characterize the asteroid. The datasets should enable new avenues for data sharing and commercial use, set criteria for prioritizing asteroids for prospecting and feed critical intelligence into planetary‑defence planning.

Fleet already has a contract to fly another instrument, a seismometer, on Firefly’s second Blue Ghost lander mission to the Moon. It has also developed and flown satellite instruments used to detect minerals on Earth.

Both companies are clearly aiming to enhance their brand name with this mission, set to launch in 2028.

More missions to Apophis when it flies past Earth in 2029?

Apophis' path past the Earth in 2029
A cartoon (not to scale) showing Apophis’s
path in 2029

There were two stories today that heralded the addition of one real and two potential new spacecraft to rendezvous with the potentially dangerous asteroid Apophis when it flies past the Earth on April 13, 2029.

First, the European Space Agency (ESA) awarded a 1.5 million euro contract to the Spanish company Emxys to build a small cubesat that will fly on ESA’s Ramses mission to Apophis. This is the second cubesat now to fly attached to Ramses, with the first designed to use radar to study Apophis’ interior.

The second CubeSat, led by Emxys, will be deployed from the main spacecraft just a few kilometres from Apophis. It will study the asteroid’s shape and geological properties and will carry out an autonomous approach manoeuvre before attempting to land on the surface. If the landing is successful, it will also measure the asteroid’s seismic activity.

Second, American planetary scientists have been lobbying NASA to repurpose the two small Janus spacecraft for a mission to Apophis. These probes were originally built to go to an asteroid as a secondary payload when the Pysche asteroid mission was launched, but when Pysche was delayed they could no longer go that that asteroid on the new launch date. Since then both Janus spacecraft have been in storage, with no place to go.

The scientists say they could easily be repurposed to go to Apophis, but NASA will have to commit to spending the cost for launch, approximately $100 million. NASA officials were not hostile to this idea, but they were also non-committal. I suspect no decision can be made until the new administrator, Jared Isaacman, is confirmed by the Senate and takes office.

Time however is a factor. The longer it takes to make a decision the fewer options there will be to get it to Apophis on time.

At the moment there is only one spacecraft in space and on its way to Apophis, and that is the repurposed Osiris-Rex mission, now called Osiris-Apex. Japan might also send a craft past Apophis as part of its mission to another asteroid.

Learning as much as we can about Apophis is critical, as there is a chance it will impact the Earth sometime in the next two hundred years.

Engineers confirm OSIRIS-APEX successfully completed its second of six close fly-bys of the Sun

Engineers have now confirmed that the asteroid probe OSIRIS-APEX successfully completed its second of six close fly-bys of the Sun in September, using its solar panels to shield its instruments from the Sun’s heat and light.

On Jan. 23 the mission team completed its review of all the data recorded by the spacecraft and its instruments during the solar pass [about 46 million miles from the Sun]. “There were no surprises, and the spacecraft is operating well,” said Mike Moreau, OSIRIS-APEX deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

As planned, on Sept. 2, 2024, OSIRIS-APEX passed through perihelion — the phase of its orbit closest to the Sun. The trajectory to Apophis takes the spacecraft much closer to the Sun than it was originally designed for. Between Aug. 1 and Oct. 13, the spacecraft was configured in a special orientation that uses one of the solar arrays to shade the most heat-sensitive components, keeping them within safe operating temperatures.

Because of the improvised orientation during the close approach, full data communications was not possible until months afterward. Only now have engineers completed their analysis.

OSIRIS-APEX original mission was to visit the asteroid Bennu and return samples from it to Earth. Once that mission was successfully completed, the probe was repurposed to go to the potentially dangerous asteroid Apophis when it makes its next close approach to the Earth in April 2029.

I have embedded below a short video showing the spacecraft’s journey to get to Apophis.

ESA and JAXA sign agreement to increase cooperation and accelerate development of Ramses mission to Apophis

The new colonial movement: The European Space Agency (ESA) and Japan’s own space agency JAXA on November 20, 2024 signed a new cooperative agreement to increase their joint work on several missions, the most important of which is the proposed Ramses mission to the potentially dangerous asteroid Apophis during its 2029 close fly-by of Earth.

Two agencies agreed to accelerate to study potential cooperation for ESA’s Rapid Apophis Mission for Space Safety (RAMSES) which aims to explore the asteroid Apophis that will pass close to our planet on 13 April 2029, including but not limited to provision of thermal infrared imager and solar array wings as well as possible launch opportunities.

The two countries are already working together on two different planetary missions, the BepiColombo mission to Mercury and the Hera mission to the asteroid Dymorphos. Both are on their way to their targets. This new agreement solidifies the commitment of both to make sure Ramses is funded, built, and launched in the relatively short time left before that 2029 Earth fly-by. At the moment the ESA has still not officially funded it fully.

ESA awards OHB Italia a preliminary contract to build Ramses probe to Apophis

The European Space Agency (ESA) yesterday awarded the company OHB Italia a €63 million preliminary contract to begin work on mission dubbed Ramses that will launch in 2028 and rendezvous with the potentially dangerous asteroid Apophis when it flies past the Earth on April 13, 2029 at a distance of less than 20,000 miles.

The contract award is preliminary because the entire project still has to be approved by the ESA ministral council of nations, meeting in 2025. Because of the short development time, however, ESA’s management found funds from its existing budget to begin work.

To speed work, the project is also using as its design basis the Hera asteroid spacecraft, which was recently launched to study the binary asteroids Didymos-Dimorphos. That mission was also built remarkably fast for a European space project, going from contract to launch in just four years.

NASA has already re-tasked its OSIRIS-REx asteroid mission to head for Apophis, renaming it OSIRIS-APEX for reasons that baffle me. The mission had successfully delivered samples from the asteroid Bennu, but after completing that mission had sufficient fuel and was well placed to do this additional rendezvous as well.

NASA asks space industry for proposals on using the shelved Janus probes on mission to Apophis

NASA has now put out a request for proposals from the space industry for refitting the two Janus planetary probes, whose asteroid mission was shelved when its launch as a secondary payload was delayed due to problems with the Psyche primary payload, as a mission to the asteroid Apophis in connection with its April 13, 2029 close approach to the Earth.

NASA has been studying this new mission goal since early 2023, but apparently had failed to come up with a plan. It is now asking the private sector for suggestions on getting it done, including finding the funding for any plans.

ESA announces asteroid mission to Apophis

Apophis' path past the Earth in 2029
A cartoon showing Apophis’s path in 2029

The European Space Agency (ESA) today announced that is beginning work on an asteroid mission, dubbed Ramses, to the potentially dangerous asteroid Apophis when it makes its next close-fly of the Earth in 2029.

Ramses needs to launch in April 2028 to allow for an arrival at Apophis in February 2029, two months before the close approach. In order to meet this deadline, ESA requested permission to begin preparatory work on the mission as soon as possible using existing resources. This permission has been granted by the Space Safety programme board. The decision whether to commit to the mission in full will take place at ESA’s Ministerial Council Meeting in November 2025.

Using a suite of scientific instruments, the spacecraft will conduct a thorough before-and-after survey of the asteroid’s shape, surface, orbit, rotation and orientation. By analysing how Apophis changes during the flyby, scientists will learn a lot about the response of an asteroid to external forces as well as asteroid composition, interior structure, cohesion, mass, density, and porosity.

Based on the track record of European space projects, which appear to always proceed at a glacial pace with late problems that cause the missions to miss their launch window (with the launch of the Franklin Mars rover as the poster child), the project is getting started far too late to meet its launch date of April 2028. We shall see if Europe surprises us this time and gets the project off the ground as planned.

Right now the only confirmed mission to Apophis is OSIRIS-APEX, which was redirected to the asteroid after it delivered its samples from Bennu to Earth. Many others have been proposed, including a commercial mission, but none appear to be confirmed or under construction.

Several new missions to the asteroid Apophis proposed by commercial and governments

Apophis' path past the Earth in 2029
A cartoon showing Apophis’s path in 2029

At a conference this week several new missions to the asteroid Apophis during its close Earth fly-by in 2029 were proposed by both private companies and government entities.

  • Blue Origin is considering sending its Blue Ring orbital tug, launched in 2027 on a Falcon 9.
  • JPL proposes sending two cubesats on the orbital tug mission previously announced by the startup ExLabs.
  • NASA continues to study sending the two Janus spacecraft, since its original asteroid mission was lost when the Psyche asteroid mission was delayed.
  • The European Space Agency has two different missions under study.

With all of these missions, the big obstacle is funding. Most are either only partly funded, or not at all.

At the moment the only mission actually on its way to Apophis is OSIRIS-APEX, which having completed its sample return mission to Bennu was then sent to Apophis.

Orbital tug startup ExLabs plans mission to asteroid Apophis in 2028

The orbital tug startup Exploration Labs (ExLabs) has announced it is planning to use its tug to deliver three cubesats on a rendezvous mission to asteroid Apophis in 2028, shortly before the asteroid does a close fly-by of Earth in April 2029.

The article at the link provides no other information about this mission. In searching the web I was unable to find anything further. It seems this mission is at present nothing more than a proposal, issued at this time mostly for public relations purposes to showcase the abilities of its proposed orbital tug, presently under development.

This conclusion does not mean the mission won’t happen, only that it is very far from a reality.

OSIRIS-REx Sample from Bennu successfully recovered

Engineers today successfully recovered the asteroid sample capsule from the probe OSIRIS-REx, carrying several grams of material from the potentially dangerous asteroid Bennu.

The samples will be shipped to special facilities to protect the material from being exposed to Earth’s environment when the capsule is opened. It will take several months at least before the first research results are announced.

OSIRIS-REx, now renamed OSIRIS-APEX, now heads for the potentially dangeous asteroid Apophis, where it will orbit that asteroid beginning in 2029, shortly after Apophis makes its next close fly-by of Earth.

The twin asteroid Janus probes, stranded by Psyche delay, might go to Apophis

Apophis' path past the Earth in 2029
A cartoon showing Apophis’s path in 2029

The science team that built the twin Janus spacecraft, designed to fly past an asteroid but stranded when its launch got canceled, are now considering the potentially dangerous asteroid Apophis as a new target.

If the Janus spacecraft can find a ride by early 2028, scientists could use one or both of the spacecraft to scout out the large asteroid Apophis before its super-close approach to Earth in April 2029. (If only one spacecraft visits Apophis, scientists would see only about half of the asteroid but could send the second spacecraft elsewhere; if both spacecraft fly past the same object they can be arranged to reveal the whole surface.)

Initially the entire Janus mission had been designed on the assumption it would launch as a secondary payload when the Psyche mission to the asteroid Psyche launched last fall. When that launch had to be canceled because Psyche was not ready, Janus lost its mission. The science team has since been struggling to find a replacement, handicapped by the fact that it must go as a secondary payload.

There is a serious issue however with arriving ahead of Apophis’s close approach in 2029. The science community has discouraged such missions, because they fear a spacecraft arriving then could shift Apophis’s trajectory and actually increase the chance it will hit the Earth during a later close approach. Instead, all planetary probes presently going to Apophis in 2029 are planning to arrive after the flyby.

The risk is extremely small, but it must be considered before sending Janus to Apophis.

South Korea cancels probe to asteroid Apophis

The South Korea government has canceled its proposed unmanned probe to asteroid Apophis that had been designed to reach the asteroid during its ’29 close approach of Earth and fly in formation with it.

The science ministry, which manages state-funded space programs, recently ruled the mission “unfeasible” and decided not to request the $307.7 million budget it initially sought for the mission. … “We’ve decided not to pursue Apophis probe mission because there were various issues making it difficult for the mission to be successful,” Shin Won-sik, a science ministry official, told SpaceNews. “To probe Apophis, we have to launch a spacecraft by 2027 at the latest. But with the rocket and spacecraft-making capabilities we have, it’s unrealistic to launch in time.”

South Korean officials insisted they are not abandoning all future asteroid missions, but merely shifting this effort to other asteroids in which there is less time pressure to launch. Right now they are considering a mission in the mid-2030s, which could also be an asteroid sample return mission.

New OSIRIS-REx photos of Bennu sample site after sample grab

Nightingale before and after sample grab
Click here and here for original images.

The OSIRIS-REx science team today released the photos the spacecraft obtained in its last fly-by of the asteroid Bennu on April 7th of the Nightngale sample site, showing how it changed after the sample grab in October 2020.

The two photos to the right compare that site, with the top image taken before the sample grab and the bottom image taken on April 7th.

Comparing the two images reveals obvious signs of surface disturbance. At the sample collection point, there appears to be a depression, with several large boulders evident at the bottom, suggesting that they were exposed by sampling. There is a noticeable increase in the amount of highly reflective material near the TAG [touch-and-go] point against the generally dark background of the surface, and many rocks were moved around.

Where thrusters fired against the surface, substantial mass movement is apparent. Multiple sub-meter boulders were mobilized by the plumes into a campfire ring–like shape — similar to rings of boulders seen around small craters pocking the surface.

Jason Dworkin, the mission’s project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, noticed that one boulder measuring 4 feet (1.25 meters) across on the edge of the sampling site seemed to appear only in the post-TAG image. “The rock probably weighs around a ton, with a mass somewhere between a cow and a car.”

Dante Lauretta, of the University of Arizona and the mission’s principal investigator, later pointed out that this boulder is likely one of those present in the pre-TAG image, but much nearer the sampling location, and estimates it was thrown a distance of 40 feet (about 12 meters) by the sample collection event.

The sample grab arm penetrated the surface by more than a foot, and that event is marked by that dark depression at the center of the site.

OSIRIS-REX will now prepare for its May 10th engine firing that will send it on its route back to Earth to return that sample in September 24, 2023. After that the spacecraft could be sent on another mission, this time to the potentially dangerous asteroid Apophis.

South Korea’s leader announces his nation’s goals in space

The new colonial movement: Moon Jae-in, South Korea’s president since 2017, on March 25th gave his first speech focused on his nation’s goals in space, outlining plans to encourage private enterprise as well as achieving an unmanned mission to the Moon by 2030.

His speech listed three main programs. First, they are developing their own home-built rocket, dubbed the KSLV-2, which they hope to launch on its first orbital test flight by October of this year.

Second, he touted a project to send a probe to the asteroid Apophis in 2029. I described this probe in my November 2020 report on a science conference focused entirely on Apophis. If all goes well, they hope to have the probe fly in formation with the asteroid as it makes its close approach that year.

Third, he committed his nation to landing an unmanned lander on the Moon by the end of this decade. (Sound familiar?)

While much of this was the typical photo-op stuff that politicians love, designed mostly to enhance their public image, Moon did make it clear their goals are also to foster a new private aerospace industry that would compete in the emerging new space market.

Moon underscored the role of the private sector in enhancing Korea’s space development capabilities. To that end, he said, the government will step up efforts to build an “innovative industrial ecosystem that nurtures global space companies such as SpaceX.”

Another issue he put forth was strengthening international competitiveness of made-in-Korea satellite systems, in the lead-up to the introduction of 6G wireless networks, self-driving vehicles, and other products and services enabled or enhanced by satellites.

All-in-all, it is actually surprising that up to now South Korea has not made its presence felt in space. This announcement suggests they now intend to change that.
