Successful Spaceflight by SSC SPACE Rocket

This launch was conducted as part of 1[ONE] Inc.'s "Space Concierge" project.

The rocket reached an altitude of 248.5 km into space, experienced microgravity, and safely returned to Earth. The carried materials and artworks now carry the unique value of having traveled to space.

The "SubOrbital Express S1X-5" mission primarily served universities and research institutions, with only two private companies selected for payload inclusion.

Notably, 1[ONE] Inc. was the sole Japanese company among them.

1[ONE] Inc. continues to develop new products and services that leverage space experiences, under the theme of making space more accessible to the public.

"Elementary School Dream Card Project" Phase 2

The second phase of the "Elementary School Dream Card Project" was also conducted in this launch, involving 4th-grade students from Itabashi No. 10 Elementary School in Itabashi Ward, Tokyo.

This project involves students writing their "dreams for the future" on cards, which are then physically placed into the rocket's payload box and launched into space.

In the first phase in 2023, students' dream drawings were photographed, digitized, and stored on an SD card for spaceflight.

This time, in Phase 2, the actual hand-drawn dream cards were physically carried into space.

As an educational initiative to make space more relatable to children, 1[ONE] Inc. will continue its efforts to connect children's dreams with space.
