The European Space Agency’s Hera probe, launched on October 7, is currently en route to the double asteroid Dimorphos, the target of NASA’s 2022 asteroid deflection test. During its long journey, the Hera probe utilized Mars as a gravitational slingshot, presenting a unique prospect to capture images of Deimos, one of Mars’ two moons. This strategic flyby not only conserved crucial fuel but also resulted in what scientists are calling “quasi-indites” images of Deimos’ previously unseen side, sparking excitement among researchers involved in the mission.
The hera mission represents a meaningful step forward in understanding both planetary defense and the formation of celestial bodies. The probe’s journey, expected to last more than two years, underscores the complexities and challenges of deep-space exploration.
patrick Michel, an astrophysicist from the Côte d’Azur Observatory and a key figure in the scientific management of the Hera program, shared his enthusiasm upon receiving the images at the European Center for Space Operations (ESOC) in Darmstadt. At 1:51 pm precisely, even if we only received the data 4 hours later
, Michel stated, emphasizing the precision and timing of the operation. The triumphant capture of these images highlights the meticulous planning and execution involved in such a complex space mission.
The primary objective of the Hera probe, which began its journey on October 7, is to meticulously study Dimorphos, the asteroid that NASA intentionally impacted in 2022 as part of a groundbreaking planetary defense experiment. The recent flyby of Mars served a dual purpose: to harness a gravitational boost,thereby optimizing the probe’s trajectory,and to gather invaluable data about the Martian system,including detailed observations of Deimos.
The data collected during this flyby is expected to provide critical insights into the composition and geological features of Deimos, contributing to a deeper understanding of the Martian environment and the broader solar system.
Michel also emphasized the critical role of the probe’s autonomous navigation capabilities during periods of limited dialog wiht Earth.The artificial intelligence on board made it possible to guide it by relying on graphic landmarks located on the surface of mars
, he explained. This autonomous guidance system was instrumental in enabling Hera to achieve its objective of capturing images of Deimos’ far side, a feat that would have been significantly more challenging without such advanced technology.
The successful implementation of AI in guiding the Hera probe marks a significant milestone in space exploration, paving the way for more autonomous and efficient missions in the future.
The images captured by Hera are poised to make a substantial contribution to the ongoing scientific discourse surrounding the origin of Mars’ moons. We are not sure if they are the result of a giant impact with an asteroid as is the case for our own moon or if Deimos and Phobos are two asteroids which would have been captured by the gravitational field of Mars
, Michel elaborated. Unraveling the formation history of Deimos and Phobos remains a key objective for planetary scientists, as it could provide valuable clues about the early solar system and the processes that shaped the planets and their satellites.
Understanding the origins of these moons could also shed light on the potential for future resource utilization in the Martian system.
adding to the international collaborative effort to study Mars’ moons, the Japanese mission MMX is scheduled to launch in October 2026. This ambitious 4-ton probe will land on Phobos, the other Martian moon, in 2027 to collect samples for return to Earth by 2031. The MMX mission will also deploy a small rover named “Idéfix,” for which Patrick Michel shares co-responsibility for scientific progress. This international collaboration underscores the global commitment to advancing our understanding of the Martian system and its place in the broader cosmos.
the MMX mission represents a significant investment in planetary science and promises to yield invaluable data about the composition and history of Phobos.
The Côte d’Azur observatory hosted a conference on Saturday, March 22, where the images of Deimos captured by Hera were presented to the public. The conference, held at CUM in Nice, featured a 3D reconstruction of Deimos with remarkable details on its topography and relief
, according to Michel. The event was a highlight for space enthusiasts and researchers alike, providing a unique opportunity to witness the latest discoveries in Martian moon exploration.
The conference served as a platform for sharing knowledge and fostering collaboration among scientists and researchers in the field of planetary science.
In an unexpected twist, Michel revealed that he had recently collaborated with Brian May, the former guitarist of the rock band Queen, on this project. This collaboration underscores the interdisciplinary nature of space exploration and the diverse expertise required to unravel the mysteries of the solar system. The involvement of individuals from various fields highlights the broad appeal and importance of space exploration in inspiring and engaging people from all walks of life.
The collaboration with Brian May exemplifies the power of bringing together different perspectives and skill sets to advance scientific understanding.
The conference at CUM in Nice took place on Saturday, March 22, from 2:30 p.m. to 5:30 p.m. members of the European space mission Hera, including Patrick Michel, presented the images captured during the Mars flyby and discussed the challenges and triumphs of the Hera mission. The event provided a valuable opportunity for the public to learn about the latest advancements in space exploration and the ongoing efforts to understand our solar system.
