When a large solar flare reaches Earth, it can cause a geomagnetic storm, radio interference, and low-latitude auroras.

Photograph auroras to estimate their latitude and determine the impact of solar flares on Earth.

< Mission Details >

Photograph auroras over North America or west of Australia.

Japan's reliance on imports for most of its feed corn is a problem.

Depending on the situation in importing countries, there is a risk of price increases and import volume restrictions.

< Mission Details >

Photograph cornfields in South Dakota and analyze the images to understand the corn's growth status.

According to a "Study on the Trend of People Moving Away from Science," teachers are less enthusiastic about teaching science than Japanese or math (survey results of elementary school teachers). In particular, space-related lessons focus primarily on the solar system and planets, with no mention of artificial satellites.

< Mission Content >

By providing software that allows students to learn about artificial satellites, we aim to provide an opportunity to learn, spark their interest, and contribute to reducing the trend of people moving away from science.
