(B)
China's Tiangong space station has successfully returned special samples (样本) from space. Astronauts worked hard to collect space samples with robotic arms in the space station. The samples are heavy—they weigh several kilograms. Hopefully, they will help scientists study what happens to different materials and human health because of gravity.
Life in space is different. Without the Earth's gravity, astronauts don't walk—they float! To stay healthy, they must do exercise for two hours every day. The Tiangong spacecraft circles our planet about 400 kilometres above the Earth's surface. From there, astronauts have an amazing view of our beautiful planet and take many photos of it.
Scientists have an important question: Why do astronauts get weaker in space? This research may help both future space travellers and sick people on Earth.
China's space programme is a great success. The Tiangong space station has done many important experiments so far. Maybe you will have the chance to visit a space station when you grow up!
