ESA’s Hera probe captures a uncommon and detailed view of Mars and its elusive moon, Deimos, throughout an important flyby on its approach to the Didymos asteroid system.

The European House Company’s (ESA) Hera probe has given scientists a uncommon deal with—a surprising new perspective of Mars and its lesser-known moon, Deimos.
The probe, which is at the moment en path to the Didymos asteroid system, used its flyby to seize among the most detailed photos but of the Purple Planet and its tiny, mysterious moon.
Deimos like by no means earlier than: Hera’s groundbreaking Mars flyby
Whereas Mars’ bigger moon, Phobos, has been extensively studied, Deimos stays an enigma. That’s why Hera’s flyby was a golden alternative for planetary scientists. Austrian geophysicist Stefan Ulamec expressed pleasure in regards to the uncommon high-resolution photographs of the far facet of Deimos, calling them among the finest photos ever captured.
Hera’s Principal Investigator, Patrick Michel, echoed this sentiment, highlighting the scientific worth of every new glimpse of Deimos. Because the moon has been imaged far much less ceaselessly than Phobos, each contemporary perspective helps piece collectively clues about its origins and composition.
Why Hera’s Mars Flyby was an important mission step
Hera’s foremost goal is planetary defence, which means its last vacation spot is the Didymos asteroid system, the place it’s going to gather post-impact knowledge following NASA’s DART mission. However earlier than reaching its goal, the probe used a intelligent trick—a gravity help from Mars.
ESA scientists adjusted Hera’s trajectory to benefit from the Purple Planet’s gravity, which slingshotted the probe additional into deep house. In keeping with ESA, this manoeuvre not solely shortened Hera’s journey by months but in addition conserved gasoline, making the mission extra environment friendly.
Ian Carnelli, Hera’s mission supervisor, described it as ‘harvesting planet power’, a way that enables house missions to maximise effectivity utilizing minimal gasoline—essential for long-distance house journey.
How Hera’s mission might assist shield Earth from asteroids
Hera isn’t only a analysis mission—it’s a key a part of Earth’s planetary defence technique. Again in 2022, NASA’s DART mission efficiently crashed a spacecraft into Dimorphos, proving that asteroids will be deflected in the event that they pose a menace to Earth.
Now, Hera is following up on that experiment, gathering important post-impact knowledge to show asteroid deflection right into a dependable planetary defence method. As Carnelli put it, the mission is about “putting in a fully-fledged insurance coverage coverage for Planet Earth.”
Even rock legend and astrophysicist Brian Might weighed in on the significance of Hera’s mission, warning that if a big asteroid have been ever to go undetected, humanity might face the identical destiny because the dinosaurs.
With its groundbreaking photos of Mars and Deimos, and its essential planetary defence mission forward, Hera is proving to be a game-changer in each house exploration and Earth’s long-term security.
