| Adjust font size: |
Twenty Chinese students in Nanjing, the capital of east China's Jiangsu Province on Sunday spoke directly via amateur radio with an astronaut orbiting above them in the International Space Station (ISS).
The group of 20 students, aged 10 to 19, hailed from Shanghai, Guangzhou and Nanjing. They began talking with Clayton C. Anderson, a 48-year-old American astronaut at 18:50 PM at the Nanjing No.3 Middle School when the ISS was passing over Nanjing. Tang Jiewen, a student from Nanjing No.3 Middle School, asked the first question: "Can you see the Great Wall from the ISS?" "I'm sorry that I haven't seen it yet, but we hope to see it," Anderson's voice came through clearly over the radio. He also answered other questions popped out by students during the 10-minute conversation. He explained that robots are used to do simple work like fetching things. "This is the first time Chinese students have participated in the Amateur Radio Program on the International Space Station (ARISS) and spoken directly with astronauts onboard the ISS," said Wang Long, a teacher in charge of the Amateur Radio activities from Nanjing No. 3 Middle School. "Through this activity, we hope to kindle enthusiasm among students in astronaut technology and radio communication," he said, "The activity should be promoted in more schools." Questions were selected from the more than 200 proposed by students via email and hotline since August 4. To ensure good communications the school purchased some ultra-short communication equipment worth over 100,000 yuan as well as the GPS software, Wang noted. The school applied to the ARISS for the membership in April 2005. It has become the 311st organization to communicate with ISS astronauts. Questions and Answers 1.
