BOULDER, Colorado — The United Arab Emirates (UAE) House Company is shifting ahead on a one-after-another mission to the principle asteroid belt.
The probe will conduct high-speed flybys of six asteroids, finishing the spectacular sojourn with a rendezvous and orbiting of a seventh mini-world — and then deploy a small lander onto that closing area rock vacation spot.
The UAE and its companions have made important progress on the daring effort, as outlined under.
Key piece of the puzzle
The Emirates Mission to the Asteroid Belt (EMA) is projected to launch in March 2028, ending its interplanetary tour by arriving on the asteroid 269 Justitia in 2034. That rocky chunk of historical past might have migrated from a area the place big planets shaped — or from even farther out.

5 of the seven asteroid targets are carbonaceous “C-complex” rocks. That signifies that EMA can characterize a various set of carbonaceous our bodies, some probably wealthy in phyllosilicates, which kind a key piece of the puzzle relating to early photo voltaic system formation.
The UAE’s enterprising mission builds on the success of the continued Emirates Mars Mission, the primary interplanetary exploration undertaken by an Arab nation.
The EMM’s Hope orbiter launched again in July 2020, arrived at Mars in February 2021 and continues to observe the Purple Planet’s climate from above.
Collaboration
The UAE House Company in Abu Dhabi is embarking on the upcoming EMA mission in collaboration with the Laboratory for Atmospheric and House Physics (LASP), right here on the College of Colorado Boulder.
This new area trek will span 13 years, with a six-year spacecraft improvement section adopted by a seven-year voyage to the principle asteroid belt past Mars.
“As one among only some asteroid missions ever deliberate, and the primary multi-asteroid tour and touchdown mission to the principle belt, it’s extremely bold, and LASP could be very excited to be concerned,” Pete Withnell, LASP’s program supervisor for the mission, advised SPACE.com.
A joint crew of engineers from each the UAE’s Mohammed bin Rashid House Heart and LASP are scoping out the EMA mission.
EMA entails a consortium of educational and {hardware} improvement companions inside the UAE, Withnell stated. The undertaking additionally consists of a lot of worldwide “information companions,” together with LASP, the Italian House Company, the Italian Nationwide Institute for Astrophysics, Leonardo SpA, Arizona State College, Northern Arizona College and Malin House Science Techniques in San Diego.
“As the first information switch companion, LASP is working in partnership with the UAE House Company on all facets of the mission,” Withnell stated. This consists of mission design, spacecraft improvement, system testing and engineering and science crew improvement and apprenticeship. LASP additionally helps the UAE House Academy program, he stated.

Totally outfitted
The EMA probe shall be outfitted with 4 devices: a visual narrow-angle digicam, a mid-wave infrared spectrometer, a thermal infrared spectrometer and a thermal infrared digicam.
The spacecraft will use this scientific gear for quite a lot of duties, together with:
- Decide the geologic historical past and risky content material of a number of most important belt asteroids, and examine the inside construction of the rendezvous goal;
- Decide temperatures and thermophysical properties on a number of asteroids to evaluate their floor evolution and risky histories;
- Accumulate remote-sensing information on a consultant suite of asteroids to higher characterize their potential for in-situ useful resource utilization for future deep area exploration.
Here is the chosen rating card of asteroids that EMA will reconnoiter: 10253 Westerwald, 623 Chimera, 13294 Rockox, 88055 (2000 VA28), 23871 (1998 RC76), 59980 (1999 SG6) and 269 Justitia.
Asteroid assets
Heyam Alblooshi, a design engineer with the UAE House Company, spoke at this yr’s House Sources Roundtable, which was held on the Colorado Faculty of Mines in June. She was concerned in UAE’s Mars Hope mission.
Alblooshi highlighted the EMA mission and its potential to determine and characterize assets, together with volatiles, silicates and metals on a number of forms of asteroids, in addition to decide useful resource mass estimates and distributions based mostly on the inside construction of an asteroid.
EMA might help put together the best way for future asteroid useful resource use, demonstrating proximity operation maneuvers to simulate touchdown and orbital rendezvous, Alblooshi stated. She famous that the EMA lander to be deployed on the asteroid Justitia is below improvement by 971 and Sadeem — two non-public firms within the UAE. That lander design shall be finalized this yr.
Flight dynamics
Additionally engaged in EMA and a veteran of the UAE’s Mars Hope mission is Fatema Hameli, an area initiatives improvement engineer for the UAE House Company. Her work is in navigation methods for the multi-asteroid visiting asteroid journey.
“I will let you know, Mars is simple to achieve from a flight dynamics perspective. However attending to seven asteroids in the principle belt shouldn’t be simple. It’s totally difficult,” Hameli advised House.com after her speak on Aug. 13 on the 2024 Astrodynamics Specialist Convention.
That prime-tech specialist assembly was hosted by the American Astronautical Society and co-hosted by American Institute of Aeronautics and Astronautics and held in neighboring Broomfield, Colorado.
As a photo voltaic electrical propulsion mission, Hameli reported, there are lots of fashions and assumptions that go into designing EMA’s interplanetary trajectory. Latest work has gone into understanding the sensitivity of the trajectory and the general mission aims.
The still-to-be-built EMA spacecraft has two separate propulsion methods: chemical hydrazine thrusters and photo voltaic electrical propulsion xenon Corridor impact thrusters, Hameli defined. The mission will make the most of xenon for its major propulsion wants as a result of its excessive particular impulse, translating to environment friendly gas utilization for long-duration interplanetary journey, she stated.
Deciding on the exact arrival date at a rendezvous goal with asteroid 269 Justitia is vital for a profitable mission and is a crucial think about mission design, Hameli identified.
“The lander is a big step as one among our most important aims,” stated Hameli. UAE House company groups are growing the navigation software program, she stated — all of the instruments that may permit EMA to spend a few months at asteroid Justitia to discover a website for the spot touchdown.
“We continue to learn as we go,” Hameli stated. “For me, this can be a childhood dream.”
