An unmanned vessel has started a 22,000km voyage around Antarctica, The Guardian reports. The craft, described by the outlet as a "robust little" ship, set off on the journey to collect data for climate science. The Guardian published its report on Friday, 25 September 2026.
The route takes the vessel through the Southern Ocean, which The Mercury describes as wild. According to The Mercury, the craft is a robot charting the full 22,000km course. The two outlets frame the trip as a scientific mission rather than a commercial one, with climate research as the stated purpose.
The distance involved is roughly the equivalent of circling the continent's coastline, a passage known for harsh conditions. The Guardian's description of the vessel as small and sturdy suggests it was built to withstand that environment, though the available reporting does not detail its design, operator or instruments.
Both outlets present the voyage as notable for its length and for being carried out without a crew. The Mercury's headline calls attention to the robot's progress across the Southern Ocean, while The Guardian places the effort under the heading of climate science.
No further specifics — such as the vessel's name, the organisation running the mission, or the data it will collect — appear in the material available.
What to watch next: whether the vessel completes the full 22,000km loop and what its measurements contribute to Antarctic climate research.
