A new study highlights how satellite imagery can provide crucial insights into the realities of war, especially in regions where information is tightly controlled by authoritarian governments. Traditionally, researchers have relied on news reports and oral testimonies to monitor conflicts, but these methods often lack reliability and can be limited by access. Satellite technology offers a new and more objective way to observe conflict zones, even when local media or witnesses are restricted. One notable example of this is the 2017 massacre of hundreds of Rohingya civilians in the village of Chut Pyin in western Myanmar. At the time, the area was off-limits to independent journalists and investigators, making it difficult to confirm what had happened. However, satellite images later revealed that the military had burned down homes in the predominantly Rohingya neighborhood, offering clear evidence of the ethnic cleansing. This case demonstrates the power of satellite imagery in documenting human rights violations in conflict zones. Valerie Sticher, a political science researcher at the University of Zurich and lead author of the study, pointed out that most existing data on wars come from media reports, which can be biased or incomplete. Satellites, on the other hand, can cover large areas and revisit locations regularly, making it possible to track patterns and changes over time. Researchers are now working to integrate satellite data into conflict monitoring, using automated image analysis to detect early signs of conflict and generate timely alerts. In another instance, a SkySat satellite operated by the California-based company Planet captured images of a failed rocket launch from Iran's Imam Khomeini Space Center in 2019. Hannes Mueller, a conflict researcher at the Spanish National Research Council, noted that while authoritarian governments may suppress information about atrocities, they cannot hide the physical evidence from space. In Myanmar, for example, the destruction of entire villages by the military leaves visible marks that can be seen from orbit. Despite these advantages, satellites have their limitations. They require specific instructions to take images, and due to limited bandwidth, they cannot capture every location they pass over. This means that some areas may only be imaged after significant events have occurred. For example, the Syrian city of Homs was only imaged by satellites after it was attacked by the military, leaving no pre-attack data available for comparison. Looking ahead, researchers are exploring the use of artificial intelligence on satellites to process images onboard, allowing them to detect and prioritize potentially significant events automatically. This could help overcome current limitations and provide more comprehensive data. However, there are concerns about governments restricting access to satellite images, as seen in the U.S. government’s request for commercial providers to withhold high-resolution images of sensitive regions like the Gulf of Oman. This could introduce new biases and hinder the transparency needed for effective conflict monitoring. The study, published in the journal Nature on September 9, underscores the growing importance of satellite imagery in understanding and documenting conflicts, while also highlighting the challenges that must be addressed to fully realize its potential.
