"San, ni, ichi, zero" and a rocket is on its way to the International Space Station (ISS) containing 100 experiments created by Australian high school students.

The launch took place at midnight Japanese time, with a local rocket serving as courier to the station.

Australian start-up Cuberider worked with more than 1,000 students from 60 schools to come up with a range of hypotheses for astronauts from NASA to test.

"How do we get young Australians excited about science and technology?" said 23-year-old Solange Cunin, founder of Cuberider.

"I can't think of anything more exciting than a space mission."

The students pitched their experiments to the Cuberider team and the projects involve a heady combination of data collection, coding with many interactions between technology, maths, science, and surprisingly — music.

One group will create a space symphony from the data collected on board.

Temperature will make woodwind music, while the string section is dictated by data from the altitude readings.

Another will measure the radiation on the craft and whether the levels are hurting the astronauts.

Ms Cunin said the rocket will go around Earth until it meets up with the station.

"It's travelling at the speed of a bullet and it's trying to itself with the International Space Station, which is also travelling at the speed of a bullet," she said.

"Then the astronauts will unpack it and set all the student experiments up and get them running."

The kids are clearly thrilled to be involved in an international space mission.

"When I heard I got picked I was so excited to get the chance to work on something like this… it didn't really feel real thinking that something I'm working on will actually be sent up to space," 15-year-old Flynn William Innes said.

"It's just something that I never dreamt I would be doing, especially this early in my life. I think it's going to set me up for a lot of good things in the future," said another student, Jennifer Johnston.

The JAXA rocket is likely to reach the space station on December 16.
