Astronomers in Pan-Starrs Observatory in Hawaii wrote the story in 2017 when they found 'Oumuamua, the first interstellar object (ISO), which was ever observed. Two years later, the Interstellare Comet 2i/Borisov became the second ISO that has ever been observed. And on July 1, 2025, the asteroid terrestrial Impact Last Alert System (Atlas) in Rio Hurtado discovered a third interstellar object in our solar system, the comet, which is now known as 3i/atlas (OR C/2025 N1 Atlas). Like its predecessors, the arrival of this object has fueled an immense scientific interest and led to suggestions for missions that could result in future ISOS.
Examples are Project Lyra, the Interstellar Object Explorer (IOE) and the Comet Interceptor of the ESA. In a work recently listed by Prof. Abraham Loeb from Harvard University, however, the opportunity examines a mission with 3i/Atlas that has been in space for years. According to its analysis, the Juno probe of the NASA could intercept this latest interstellar object as soon as it approaches Jupiter on March 16, 2025 and today humanity gives one of the most puzzling object classes in the universe in the universe today.
Abraham Loeb is the Frank B. Baird Jr. Professor of Science at Harvard University and director of the Institute for theory and Calculation (ITC) and the Galileo Projekt in the Harvard & Smithsonian Center for Astrophysics (CFA). Adam Hibberd and Adam Crowl joined him, who are both respected scientists with the non -profit initiative for interstellar studies (i4is) based in Great Britain. The paper, which recently describes your proposal, was published online and is checked for publication in the Astrophysical Journal Letters.

Loeb, Hibberd and Crowl are no strangers for Isos and the opportunity to send spaceships to make themselves and study them up close. In 2018, Prof. Loeb became a well -known name “could the solar radiation pressure 'Oumuamua's special acceleration explain?” In this paper and in his subsequent book with the title Extra -Restral, he argued that 'Oumuamua could have been an extraterrestrial spaceship, which explained his strange behavior and the way in which attempts were made to classify it.
Similarly, Hibberd received recognition for his work with the i4is via Project Lyra. This proposed mission would “catch up” oumuamua or future isos with luminaire technology and decepted energy drive (DEP). He also worked with Marshall Euins and Space Initiatives on the enthusiastic Proxima Centauri proposal, a concept that would also rely on DEP to send a swarm of space vehicles to study the closest rocky planet beyond our solar system (proxima b). Crowl is an independent researcher and drive engineer who was previously a member of Project Icarus, a design study for an interstellar probe based on the legacy of Project Daedalus.
Since 'Oumuamua has made its close path to earth, scientists dreamed of the day on which a committed mission was able to interlock and study an interlocking visitor. In several missions, rehearsal withdrawal missions have been carried out in the past decade to form an almost earth-ending asteroid (NEAS), including Jaxas Hayabusa and Hayabusa2 probes and the Osiris Rex probe from NASA. Since asteroids and comets are essentially material that remains from the formation of the solar system, the examination of these samples provides indications of the conditions about 4.5 billion years ago.
By studying the ISOS while running through our system, scientists can learn what conditions were available in other star systems without waiting for an interlocking spaceship to reach them. But as Prof. Loeb examined in his 2018 article, an ISO could be an artificial object (like a dilapidated spaceship), which exponentially increases the opportunities for scientific research. Hibberd, Crowl and Loeb examined similar options in a recently published article in relation to 3i/Atlas: “Is the Interstellar Object 3i/Atlas Alien Technology?”. As Prof. Loeb said today by e -mail to Universe, this makes a mission particularly appealing:
[W]E show that the application of a thrust of 2.675 kilometers per second on September 14, 2025 can bring the Juno spaceship from his orbit around Jupiter to intercept the path of 3i/Atlas. The close encounter of 3i/Atlas with Jupiter offers a rare opportunity to reduce Juno from his current orbit to Jupiter in order to intercept the path of 3i/Atlas in his closest approach to Jupiter.
The brightness of 3i/atlas implies a diameter of 20 kilometers for an asteroid with a typical reflection capacity (albedo) of 5%. As I showed in a published paper shortly after the discovery of 3i/Atlas, the detection of this object requires an unsustainable mass supply of rocky material from the Milky Way over 5 years after the ATLAS telescope's survey. If 3I/Atlas have a diameter of 20 kilometers, it may have attacked the inner solar system, as expected from the alien technology.

As shown in her study, 3i/Atlas will reach about 53.6 million km (33.25 million million) or 0.358 AU on March 16, 2026. At this point, a shift in the orbit of the Juno spaceship would allow the path from 3I/in the approach to the Giant. This proposal deals with the challenge of building and using a spaceship on the construction and introduction of a spacecraft to intercept 3i/atlas before it takes the closest for the sun (October 29, 2025) and leaves our solar system. As Hibberd explained:
It is quite clear that a mission that has been started from earth to 3i is completely impossible, since we warn little before you arrive in the solar system. In addition, it would not be within the power envelope of the proposed mission of the ESA -Comet -Interceptor mission, in other words, even if a spaceship had been waiting on the sun/earth -l2 position. Now 3i by chance comes very close to Mars, Jupiter and Venus, which is a strange coincidence in itself and it is unlikely that it will be repeated with every future ISO.
In view of the above -mentioned serendipities and the impossibility of recognizing a special probe, in order to meet them in good time, it therefore seems sensible to inquire whether an existing spaceship that surrounds Mars or Jupiter could be used for a catch or a close approach. In this context, work is worthwhile, and such an analysis only applies to Isos, which accidentally have close encounters with the planets, which I have articulated will indeed be very rare.
In order to determine the optimal flight path that would lead to a rendezvous, the team was based on optimal inter -planetary trajectory software (Oits), a package that was originally developed by Hibberd for Project Lyra in 2017. As Hibberd explained, it enabled them to solve the problem of determining the orbits and speeds of Juno and 3i/Atlas (also known as Lambert problem), but only for an orbital cycle. In order to measure how close the Juno probe with a minimal bivide could reach the interstellar comets, Hibberd used other tailor-made software.
This consisted of the C software, which he developed with three libraries-the NASA JPL, navigation and NAIF (NAF information facility) as well as space vehicles, planet, instrument, C-matrix, events (spice) software that enabled the team to create a precise prediction of Jupiter and Junos Orbits. “The rebound software was also used to integrate the movement of all three bodies, and Nomad found that the minimum speed Juno was necessary to create an offset 3i/Atlas. As Loeb indicated, the results showed that catching up with a Jupiter Colonel Manöver:
If this exciting new goal is feasible, the mission of Juno will be rejuvenated and its scientific lifespan will be extended beyond March 14, 2026. So far we have examined a section of Juno with 3i/Atlas. The optimal option includes a Jupiter Oberth maneuver, in which on September 9, 2025 just 8 days before the originally intended date of termination for Juno's burglary in the atmosphere of Jupiter, an application of ∆V is required. After this thrust was delivered to the height of Juno, another ∆V is delivered, which is a Jupiter Oberth maneuver and on March 14, 2026 leads to a possible section of the Target 3i/Atlas.

They also show how Juno's instrument suite could all be used to examine the nature of 3i/atlas from a close distance. This includes its near-infrared spectrometer, the magnetometer, the microwave radiometer, the gravity science instrument, an energetic particle detector, the radio and plasma cameras, the UV spectrograph and the visible camera. The data that range from spectra and images to energetic emissions will answer questions about the composition of the property and inform us volumes about the home system and the conditions in the formed conditions.
“Our paper depends on a remarkable but verifiable hypothesis that 3I/Atlas is a functioning technological artifact that I and my two co authors do not necessarily attribute,” added Loeb. “However, this hypothesis earns a scientific analysis for two reasons: the consequences, if the hypothesis is as correct, could possibly be bad for humanity and possibly require defensive measures to take this (although they could prove to be unsuccessful). [Second,] The hypothesis is an interesting exercise and is fun to research regardless of your probable validity. “
However, the latest pictures taken by the Hubble world space telescope indicate that this possibility could not be off the table. Based on the brightness distribution of the surrounding coma, researchers have estimated that the core has an effective radius of less than 2.8 kilometers (~ 1.75 mi). However, all questions about your true nature are solved as soon as a) 3i/Atlas comes closer to the sun and begins to fill gases through sublimation, or b) The Juno probe has the option of examining it up close.
Regardless of the result, the results will surely be fascinating and tell us a lot about what is beyond the solar system.
