Video: 00:01:38 On 11 June, engineers at OHB’s facilities in Germany joined together the two main parts of ESA’s Plato mission.
They used a special crane to lift Plato’s payload module, housing its 26 ultra-sensitive cameras, into the air and carefully line it up over the service module. The supporting service module contains everything else that the spacecraft needs to function, including subsystems for power, propulsion and communication with Earth.
With millimetre-level precision, the engineers gently lowered the payload module into place. Once perfectly positioned, the team tested the electrical connections.
Finally, they securely closed a panel that connects the payload module to the service module both physically and electronically (seen ‘hanging’ horizontally above the service module in this image). This panel, which opens and closes with hinges, also contains the electronics to process data from the cameras.
Now in one piece, Plato is one step closer to beginning its hunt for Earth-like planets.
In the coming weeks, the spacecraft will undergo tests to ensure its cameras and data processing systems still work perfectly.
Then it will be driven from OHB’s cleanrooms to ESA’s technical heart (ESTEC) in the Netherlands. At ESTEC, engineers will complete the spacecraft by fitting it with a combined sunshield and solar panel module.
Following a series of essential tests to confirm that Plato is fit for launch and ready to work in space, it will be shipped to Europe’s launch site in French Guiana.
The mission is scheduled to launch on an Ariane 6 in December 2026.

ESA’s Plato (PLAnetary Transits and Oscillations of stars) will use 26 cameras to study terrestrial exoplanets in orbits up to the habitable zone of Sun-like stars.
Plato's scientific instrumentation, consisting of the cameras and electronic units, is provided through a collaboration between ESA and the Plato Mission Consortium. This Consortium is composed of various European research centres, institutes and industries, led by the German Aerospace Center (DLR). The spacecraft is being built and assembled by the industrial Plato Core Team led by OHB together with Thales Alenia Space and Beyond Gravity.

These images captured by the Curiosity rover in 2014 reveals yet another unexplained aerial phenomenon in the Martian atmosphere, a cigar-shaped object with a consistent width and rounded ends.
What makes this anomaly particularly compelling is the sharp clarity of the image. According to Jean Ward the stars in the background appear crisp and unblurred, indicating that the object is not the result of motion blur or a long exposure. Notably, the object appears in five separate frames over an 8-minute span, suggesting it is moving relatively slowly through space, uncharacteristic of a meteorite entering the atmosphere. It also lacks the fiery tail typically associated with atmospheric entry.
Rather than a meteor, the object more closely resembles a solid, elongated craft of unknown origin. When oriented horizontally, it even appears to feature a front-facing structure, possibly a porthole or raised dome, hinting at a cockpit or command module.
Whether this object is orbiting beyond the visible horizon or connected to the surface far in the distance, its sheer size is unmistakable. Its presence raises compelling questions, could this be further evidence of intelligently controlled craft, whether of extraterrestrial or covert human origin, navigating through Martian airspace?View the full article

NASA/JPL-Caltech/ASU Arsia Mons, one of the Red Planet’s largest volcanoes, peeks through a blanket of water ice clouds in this image captured by NASA’s 2001 Mars Odyssey orbiter on May 2, 2025. Odyssey used a camera called the Thermal Emission Imaging System (THEMIS) to capture this view while studying the Martian atmosphere, which appears here as a greenish haze above the scene. A large crater known as a caldera, produced by massive volcanic explosions and collapse, is located at the summit. At 72 miles (120 kilometers) wide, the Arsia Mons summit caldera is larger than many volcanoes on Earth.

Sol 4546: Martian Jenga
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on May 19, 2025 — Sol 4544, or Martian day 4,544 of the Mars Science Laboratory mission — at 02:23:29 UTC. NASA/JPL-Caltech Written by Michelle Minitti, Planetary Geologist at Framework
Earth planning date: Monday, May 19, 2025
Have you ever played the game Jenga, where you remove one wooden block from a stack, gently place it on another part of the stack, then repeat over and over as you try to keep the stack from toppling over? There are strategies to the game such as what blocks you can afford to remove, and where you can manage to place them without throwing the structure out of balance. That is very much how planning felt today — but instead of wooden blocks, the objects the science team was moving around were science observations in the plan.
We had an unusual one-sol plan today so there were very restricted time windows in the plan in which to fit science observations and our next drive. We are driving through an area with criss-crossing fracture sets (which we call boxwork structures) large enough to be seen from orbit. Since they have only recently come within our view, there is no shortage of new observations to make of the fractures as we try to understand the processes that led to their formation. If the fractures were caused by extensive fluid flow through the Martian crust, understanding them would be an important contribution toward tracing the history of Martian water.
To fit in all the desired observations — including APXS and MAHLI on a DRT-brushed target, multiple ChemCam RMI and Mastcam mosaics, and a ChemCam LIBS analysis — in addition to environmental monitoring activities and a long drive, the team used every trick in its book to achieve a delicate balancing act of science, time, and power. Some activities were trimmed to fit in smaller time windows, others were moved to less-constrained parts of the plan, and other activities were placed in parallel with each other to take advantage of Curiosity’s ability to multitask.
Once our planning Jenga game was over, the team had won — we had a complete and perfectly balanced plan! Who says you cannot teach an old dog (4,546-sols-old) new tricks?

To create a crumbly crater rich in ice and chunky blocks soaked in layers of martian history – like this one recently observed by the European Space Agency’s Mars Express – follow this recipe:
Toss a space rock into Mars to form a classic circular base Layer with molten lava Carve channels with liquid water Chill to create ice, and freeze-thaw multiple times to slowly expand crater edges Sprinkle generously with volcanic dust, and leave to set Serve to hungry Mars fans!
