Fish sent into space 坐火箭升空的魚

German scientists have launched a rocket carrying 72 small fish on a short space flight. The researchers wanted to study motion sickness.

The fish, cichlids, were put in an unmanned rocket. Professor Reinhard Hilbig was in charge of the project.

The thumbnail-sized fish were filmed as they swam around in small aquariums. Because they were in space they were weightless during the 10-minute space flight.

The German team will now study the video to see if some of the fish swam in circles. That is what fish do when they experience motion sickness.

The scientists hope the experiment can help them understand why only some people experience motion sickness. The mechanisms involved are similar for both fish and humans.

Hilbig said the fish landed safely and appeared to be in good condition.

"They were very happy, I think they want to have another flight," he said.

Hilbig said that cichlids were a good choice, "Goldfish are a little bit fat and messy, while the cichlid fish is a well-trained, sporty fish with muscles," he said. (STAFF WRITER WITH AP)
