太空科技讓動物變身抓捕偷獵者的超級英雄！

A new satellite called Icarus is changing the way scientists protect wildlife in Africa. This satellite can track animals from space by picking up signals from tiny tags attached to their ears. These tags send information about where the animals are and how they are behaving. By watching for signs of panic, like when animals suddenly run away, scientists can tell if there might be poachers in the area. This technology could help save animals like rhinos, elephants, and cheetahs from being hunted.

In Namibia, at a place called Okambara Elephant Lodge, scientists tested this system. They acted like hunters and walked through the park, making loud noises to see how the animals would react. Zebras and wildebeest ran away quickly, while giraffes stayed calm and watched. The scientists used drones to record everything from above. They also put GPS tags on about 5 percent of the large animals in the park. These tags send data to the satellite, which helps scientists understand how animals move and react to danger.

The information from the tags is used to create warning systems for park rangers. If many animals start running at once, the system can send an alert to the rangers so they can check for poachers. The tags are very advanced and can measure things like heart rate, body temperature, and even the weather around the animal. In other parks, like Kruger National Park in South Africa, these tags have already helped save wild dogs from traps. The scientists hope to put tags on 100,000 animals by 2030. With more satellites in space, they will be able to track animals all over the world and protect them from harm. This new technology is a big step forward in wildlife conservation.
