NASA Astronaut Captures Stunning Image of Madagascar’s “Bleeding” River
NASA astronaut Don Pettit has once again turned his lens toward Earth, capturing a breathtaking image of the Betsiboka River estuary in Madagascar from the International Space Station (ISS). The photo, taken 250 miles above our planet, reveals a vivid red waterway that Pettit described as resembling “the arteries in your retina.”
The striking red hue of the Betsiboka River is caused by the high concentration of iron-rich sediments carried by the waterway. According to NASA’s Earth Observatory, the estuary is a prime example of rapid coastal change driven by extensive deforestation. A century of logging in the region has led to severe erosion, with the luminous red soils washing into rivers after heavy rains. Other astronauts have poignantly described the scene as madagascar “bleeding into the ocean.”
The environmental impact of this erosion is notable. Sediment accumulation has clogged waterways, preventing ships from navigating upriver as they once could. Tropical storms, such as Cyclone Gafilo in 2004, have exacerbated the issue, causing massive flooding and sediment flow. in response, the Malagasy government has implemented programs to combat deforestation, promote reforestation, and reduce soil erosion.
Pettit, a seasoned astronaut with four space missions under his belt, has a knack for capturing dramatic vistas. Last year, he shared an image of moonlight reflecting off the Amazon basin, which he likened to “flowing silver snakes.” Another photo,showing light reflecting off SpaceX Starlink satellites,reminded him of “cosmic fireflies.”
At 69, Pettit is NASA’s oldest serving astronaut and continues to share his unique perspective from the ISS. In a recent interview, he discussed his passion for photography, describing how microgravity conditions can even assist in changing camera lenses—a process he demonstrated in a playful video.

NASA astronaut Don Pettit’s recent photograph of the Betsiboka River in Madagascar has drawn global attention to the environmental challenges facing the island nation. The striking red hues of the river, caused by iron-rich sediments, highlight the severe erosion resulting from deforestation and tropical storms. To delve deeper into this issue, we spoke with Dr. Emily Carter, an environmental scientist specializing in riverine ecosystems and erosion control.
The Betsiboka River’s Unique Color and Erosion
Senior Editor: Dr.Carter, what causes the Betsiboka River’s distinctive red color, and why is this phenomenon importent?
Dr. Emily Carter: The Betsiboka River’s luminous red color is primarily due to the high concentration of iron-rich sediments in the water. this sediment is a direct result of severe erosion in the region, driven largely by deforestation. When heavy rains occur, the exposed soil is washed into the river, creating this vivid, almost otherworldly effect. While it’s visually striking, it’s also a stark reminder of the environmental damage caused by human activity.
The Environmental Impact of Sediment Accumulation
Senior Editor: How has the sediment accumulation affected the river and surrounding areas?
Dr. Emily Carter: The sediment accumulation has had several detrimental effects. First, it has clogged waterways, making it tough for ships to navigate the river as they once could. This has impacted local trade and transportation. Additionally, the sediment has altered the river’s ecosystem, affecting aquatic life. During tropical storms, like Cyclone Gafilo in 2004, the increased sediment flow has led to massive flooding, further exacerbating the damage to communities and infrastructure.
Government Efforts to Combat Erosion
Senior Editor: What steps has the Malagasy government taken to address this issue?
Dr.Emily Carter: The Malagasy government has implemented several programs aimed at combating deforestation and promoting reforestation. These initiatives are crucial for reducing soil erosion and restoring the natural landscape. Additionally, they’ve introduced erosion control measures, such as terracing and planting vegetation along riverbanks, to stabilize the soil and prevent further sediment flow. While these efforts are commendable, sustained action and international support are essential to address the root causes of the problem.
Don Pettit’s Photography and Its Broader Implications
Senior editor: How does Don Pettit’s photography from the ISS contribute to our understanding of environmental issues like this one?
Dr. Emily Carter: Don Pettit’s photographs provide a unique viewpoint on Earth’s environmental challenges. From space,we can see the interconnectedness of ecosystems and the impact of human activity on a global scale.His images of the Betsiboka River not only highlight the beauty of our planet but also serve as a powerful visual reminder of the urgent need for environmental conservation. By sharing these perspectives, he encourages us to reflect on our relationship with nature and the importance of lasting practices.
The Role of Photography in Raising Awareness
Senior editor: Beyond the ISS,how can photography and visual storytelling play a role in raising awareness about environmental issues?
Dr. Emily Carter: Photography is an incredibly effective tool for storytelling and raising awareness. It can evoke emotions,spark curiosity,and inspire action in ways that data and reports often cannot. Images like don pettit’s capture the imagination and make complex environmental issues more accessible to the public. By showcasing both the beauty and the fragility of our planet, photographers can play a vital role in driving conversations about conservation and encouraging individuals and policymakers to take meaningful steps toward protecting our environment.
