## Body

### Overview
Hayato was a former Japanese CubeSat, a type of miniaturized satellite. It was also known by several aliases including Kagoshima Satellite, K-SAT, KSAT, and ハヤト. The satellite was operated by Kagoshima University, a higher education institution based in Japan.

### Classification and Purpose
Hayato was classified as an instance of a CubeSat, which are miniaturized satellites typically made up of 10cm-sided cubic modules. It was also categorized as an Earth observation satellite, meaning its primary purpose was to observe Earth from orbit.

### Launch Details
*   **Launch Date**: Hayato was launched on May 20, 2010, at 21:58:22 UTC.
*   **Launch Vehicle**: The satellite was carried into orbit by an H-IIA rocket, specifically the H-IIA-17 variant. The H-IIA is a Japanese expendable medium-lift launch vehicle.
*   **Launch Site**: The launch originated from Yoshinobu Launch Complex Launch Pad 1.
*   **Identifiers**: Its COSPAR ID was 2010-020A, and its NSSDCA ID was also 2010-020A.

### Operational Life and End
A significant event in Hayato's operational life was its rocket launch on May 20, 2010. However, its operational period was brief. The satellite experienced atmospheric entry, marking the end of its mission, on July 14, 2010. This date is also recorded as the time of the object's orbit decay.
