Students at Nelson's Victory Primary School will put their questions to the astronauts on the International Space Station tomorrow.
Using amateur radio, 20 students will put pre-prepared questions to the astronauts - and it's hoped one of the Christchurch children who've enrolled at Victory since the earthquake will be included in the group.
Victory School volunteer Scott Smithline said everything was ready and he was optimistic the scheduled contact with the in-orbit crew on the International Space Station would go to plan, and that they would be able to include a question from a Christchurch child.
"It would provide a ray of sunshine and some hope as these children settle into a new school - given the catastrophe that we have had over the past week," he said.
The students were the youngest group in New Zealand to be involved in the Amateur Radio on the International Space Station programme said School Board of Trustees chairwoman Helen Watson.
"The students are very excited and have been practicing asking their questions," she said. "Because the space station will only be in range of Nelson for 10 minutes, everything must be timed precisely and we have to follow a strict countdown checklist."
The whole school will be able to listen to the astronauts answering the children's questions. The contact is scheduled to start at 12.33pm.
