This image from the European Space Agency’s Mars Express shows the Arsia Mons Elongated Cloud: the most visually striking cloud on the Red Planet.
The image was taken by Mars Express’s High Resolution Stereo Camera on 24 June 2024; it shows a region of Mars just under 1250 km across (an area of 780 000 square km), with the cloud stretching out for around 980 km.
This white wisp of water ice emerges downwind of the 20-km-tall Arsia Mons volcano. It forms, grows, and fades on a daily basis, stretching out for up to 1800 km – nearly twice the length of the UK – before quickly evaporating. This cycle repeats every morning for several months.
Researchers now think that exotic physics (known as homogeneous nucleation) might be behind this cloud’s formation – physics related to how water vapour turns into icy cloud particles.
The full story
[Image description: Tan-coloured horizontal rectangle showing part of the surface of Mars imaged by an orbiting satellite. On the right is a ring of concentric circles that indicate a volcano. Stretching to the left of the volcano is a long wisp of white cloud, which seems to emanate from the volcano. We also see the shadow of the cloud just above the cloud itself.]

Exactly two years after launch, ESA’s Hera planetary defence mission has caught its first glimpse of its destination: the Didymos binary asteroid system, seen from an approximate distance of 236 500 km away.
By combining multiple images and performing photometric analysis, the Hera mission team was able to identify Didymos against the background star field, seen in visible light, smaller than an individual pixel but sufficiently bright to be detected by the camera.
For now, Hera’s destination appears as little more than a single bright point. In reality, it is a binary asteroid system: the 780-m-diameter Didymos is orbited by the 150-m-diameter Dimorphos. In September 2022, NASA’s DART spacecraft deliberately impacted Dimorphos, changing its orbit around Didymos and demonstrating asteroid deflection for the first time.
Hera will have to travel much closer before its cameras can resolve the two asteroids separately. But from now on, its destination is no longer just a calculated point in space: Hera can see it.
When Hera reaches Didymos, it will perform a close-up investigation of the impact site and measure in detail how Dimorphos responded to DART’s collision.
These measurements will help turn the DART impact experiment into a well-understood and potentially repeatable planetary defence technique.
Have questions about Hera, its journey or what awaits it at Didymos? Ask the Hera Space Companion — an AI companion connected to the mission and designed to let everyone follow and explore ESA’s first planetary defence mission as it unfolds.
