Neeews Summary
The following content was published online. A translated summary is presented below. See the source for details.
The European Space Agency’s HERA mission, en route to investigate the impact of NASA’s DART spacecraft on the asteroid Dimorphos, made a detour to capture rare images of Mars’ smaller moon, Deimos. During the flyby, the HERA spacecraft came as close as 5,600 kilometers to the Martian surface, reaching a speed of 33,480 kilometers per hour. The spacecraft used the opportunity to test its scientific instruments, including its “HyperScout” and thermal infrared imagers, which allowed it to capture around 600 photographs, including rare views of the 12.5-kilometer-wide Deimos.
The origin of Deimos and its larger counterpart, Phobos, remains a subject of debate, with some scientists believing they were once asteroids captured by Mars’ gravity, while others think they could have been ejected from the planet’s surface. The new images from HERA are expected to provide additional insights into the composition and formation of these Martian moons, which could help solve this longstanding mystery.
After the Mars flyby, HERA will turn its focus back to the asteroid Dimorphos, where it aims to study the effects of NASA’s DART mission, which deliberately crashed into the asteroid in 2022 as a test of Earth’s planetary defense capabilities. The data collected by HERA could help determine whether this technique could be an effective way for Earth to defend itself against potentially threatening asteroids in the future.

Our Commentary
Background and Context
The HERA mission is part of the European Space Agency’s efforts to study the impact of NASA’s DART mission, which deliberately crashed into the asteroid Dimorphos in 2022 as a test of Earth’s planetary defense capabilities. The HERA mission is designed to study the effects of the DART impact and gather data that could help inform future planetary defense strategies.
During its journey to Dimorphos, the HERA spacecraft made an unexpected detour to capture images of the Martian moon Deimos, which is one of two moons orbiting Mars. This detour provided a rare opportunity for the HERA mission to study the composition and formation of the Martian moons, which have long been a subject of scientific debate.
Expert Analysis
According to planetary scientists, the images and data collected by HERA during its flyby of Deimos could help unravel the mystery of the origins of Deimos and its larger counterpart, Phobos. As some experts suggest, the Martian moons may have once been asteroids captured by Mars’ gravity, while others believe they could have been ejected from the planet’s surface. The information gathered by HERA could provide valuable insights into the early formation of the Solar System.
Moreover, the data collected by HERA during its encounter with Deimos could also be crucial for future planetary defense efforts. Understanding the composition and behavior of small celestial bodies, like the Martian moons, is essential for developing effective strategies to protect Earth from potentially hazardous asteroids.
Additional Data and Fact Reinforcement
According to the article, the HERA spacecraft came as close as 5,600 kilometers to the Martian surface during the flyby, reaching a speed of 33,480 kilometers per hour. The spacecraft used this opportunity to test its scientific instruments, including its “HyperScout” and thermal infrared imagers, which allowed it to capture around 600 photographs of the 12.5-kilometer-wide Deimos.
Related News
In related news, NASA’s Perseverance rover, which is currently exploring the Jezero Crater on Mars, recently captured stunning images of Deimos passing in front of the Sun. These images, combined with the data gathered by HERA, are expected to provide a more comprehensive understanding of the Martian moons and their role in the planet’s history.
Summary
The HERA mission’s unexpected encounter with the Martian moon Deimos has yielded rare and valuable data that could help solve longstanding mysteries about the origins and evolution of these celestial bodies. The images and information gathered during this flyby will not only advance our scientific understanding of the Solar System but also contribute to the critical work of developing effective planetary defense strategies against potentially hazardous asteroids. As the HERA mission continues its journey to study the impact of the DART spacecraft on Dimorphos, the insights gained from this Deimos encounter will undoubtedly prove invaluable in shaping our future efforts to protect our planet from cosmic threats.
