The Technology Innovation Institute (TII) has unveiled the UAE-built probe that will land on asteroid 269 Justitia as part of the Emirates Mission to the Asteroid Belt (EMA). Designed and tested in Abu Dhabi, the autonomous probe will travel with the MBR Explorer before separating for a close-range encounter with Justitia after an approximately five-billion-kilometer journey.
The UAE’s ambitions in deep-space exploration are moving from spacecraft development to autonomous operations, with the Technology Innovation Institute (TII) unveiling the probe it has built for the Emirates Mission to the Asteroid Belt.
The probe is scheduled to travel to Colorado, where it will undergo final integration with the MBR Explorer spacecraft ahead of the mission’s planned March 2028 launch from Japan. EMA will send the spacecraft on a multibillion-kilometer journey through the inner Solar System and into the main asteroid belt, with six asteroid flybys followed by a rendezvous with 269 Justitia.
What makes TII’s hardware particularly significant is that it is not simply another scientific instrument aboard the spacecraft. It is the mission’s deployable surface probe and is designed to separate from MBR Explorer near Justitia, descend independently and make contact with the asteroid.
The probe was designed, built and tested in Abu Dhabi by TII’s Propulsion and Space Research Center in collaboration with the UAE Space Agency, HEX20, Khalifa University and the UAE University’s National Space Science and Technology Center. The UAE Space Agency previously confirmed its agreement with TII to develop the EMA lander for Justitia.
The engineering challenge extends beyond reaching the asteroid. Once deployed, the probe is expected to operate autonomously, without continuous commands from Earth or the MBR Explorer. TII says its onboard software will determine when to capture images, how many to acquire and which images are worth retaining.
That autonomy is supported by a digital processing unit developed by TII that manages onboard processing, image selection and power management. Two cameras—a wide-field camera and a narrow-field camera—will provide both contextual observations and higher-resolution imagery.
The probe will also begin collecting data before reaching Justitia. During the cruise phase, it will image objects alongside the spacecraft’s other payloads, with data transmitted back to Earth at approximately six-month intervals. At Justitia, the system will attempt to capture observations from much closer to the surface than the main spacecraft can safely achieve.
That distinction is important scientifically. The MBR Explorer is expected to spend roughly seven months around Justitia, beginning in a high orbit and descending through progressively lower orbits. The probe is then planned for deployment during a low-altitude pass in early 2036. Its surface observations could provide information about material beneath the asteroid’s outer layer that cannot be characterized as effectively from orbit.
Justitia is an unusual target. Scientific observations indicate that the roughly 54-kilometer asteroid has an exceptionally red spectrum compared with many neighboring main-belt objects. Research has suggested that its spectral characteristics may be consistent with material associated with objects from the outer Solar System, although its precise origin and evolution remain subjects of scientific investigation. A 2025 Planetary Science Journal study described Justitia as an unusual member of the asteroid population and identified it as EMA’s final rendezvous target.
The mission could therefore provide scientists with an unusual opportunity to study an object that may preserve clues about material from the colder regions of the early Solar System without requiring a mission to the Kuiper Belt itself.
EMA is also becoming a technology-development program for the UAE. The UAE Space Agency describes the mission as a 13-year program, combining spacecraft development with a seven-year journey through the main asteroid belt. The agency says the mission will study seven asteroids and investigate their characteristics, origins, evolution and potential water-bearing, organic and volatile materials.
The mission has a strong local-development component. The UAE Space Agency says 50% of EMA’s project work has been allocated to UAE-based private-sector companies, linking the scientific mission with the country’s effort to develop domestic space engineering, research and commercial capabilities.
For the broader technology industry, the probe’s autonomous architecture is arguably as important as its destination. Deep-space systems cannot depend on low-latency communication for every operational decision. Hardware, software, thermal systems, power management and onboard processing must continue functioning across years of travel and then execute a tightly constrained sequence during the final encounter.
That makes EMA an example of a wider shift in spacecraft engineering toward increasingly independent systems. While the mission is not primarily an artificial-intelligence project, its onboard decision-making and processing architecture illustrate the same technological direction seen across autonomous robotics: moving more perception, selection and operational control closer to the machine itself.
The UAE has already positioned EMA as a flagship national space program. The agency has linked the mission to its National Space Strategy 2031 and broader efforts to develop local engineering talent, private-sector participation and international research partnerships.
If the mission remains on schedule, MBR Explorer will launch in 2028, spend years navigating toward the asteroid belt and ultimately deliver TII’s autonomous probe to one of the Solar System’s more unusual asteroids. The result would be both a scientific expedition and a long-duration demonstration of the UAE’s ability to design and operate increasingly complex deep-space technology.
Market Landscape
The commercial and strategic space sector is increasingly moving beyond launch vehicles and satellites toward deep-space exploration, autonomous spacecraft, advanced propulsion and mission-specific robotics.
EMA fits this trend by combining international mission partnerships with locally developed spacecraft technology. The UAE Space Agency says the mission is designed to build national capabilities while involving UAE-based private companies in a significant portion of the work.
The probe also highlights an important engineering trend: autonomy becomes increasingly valuable as spacecraft travel farther from Earth. Communication delays and limited bandwidth make onboard processing, fault management, image selection and operational decision-making critical capabilities.
From a technology perspective, EMA therefore sits at the intersection of space robotics, autonomous systems, embedded computing, scientific imaging and advanced aerospace engineering rather than conventional satellite operations.
