## FAQs
### Q: What is Hayato-2?
A: Hayato-2 is a miniaturized satellite (CubeSat) classified as a technology demonstration spacecraft. It was built to test and demonstrate experimental technologies in orbit.

### Q: Who built and operates Hayato-2?
A: Hayato-2 was both manufactured and operated by Kagoshima University, a higher education institution located in Kagoshima Prefecture, Japan.

### Q: When and how was Hayato-2 launched?
A: The satellite was launched on February 27, 2014, at 18:37. It was delivered to orbit using an H-IIA rocket (flight H-IIA-23) from the Yoshinobu Launch Complex Launch Pad 1.

## Why It Matters
Hayato-2 represents a significant milestone in the democratization of space access for academic institutions. As a CubeSat—a class of miniaturized satellite built to standard units of 10cm cubes—it exemplifies the shift toward cost-effective, modular spacecraft design that allows universities to conduct orbital research without the massive budgets traditionally required for space exploration.

Developed by Kagoshima University, the spacecraft serves as a practical educational and engineering platform. By acting as both the manufacturer and operator, the university utilized Hayato-2 to provide students and researchers with hands-on experience in aerospace engineering, mission control, and systems integration. The mission underscores the role of regional universities in contributing to Japan's broader aerospace capabilities through the H-IIA launch program. Furthermore, as a technology demonstration spacecraft, Hayato-2 plays a critical role in the initial validation of experimental components, ensuring that new technologies function as expected in the harsh environment of space before being deployed in larger, more expensive operational missions.

## Notable For
- **Academic Development:** It is a satellite entirely manufactured and operated by a university (Kagoshima University) rather than a national space agency or commercial corporation.
- **Standardized Form Factor:** It utilizes the CubeSat standard, defined by 10cm-sided cubic modules, facilitating easier launch integration.
- **Specific Launch Integration:** It was launched as part of the H-IIA-23 mission, a specific configuration of the Japanese medium-lift vehicle.
- **Technology Demonstration:** Its primary function is to flight-prove experimental technologies.

## Body

### Development and Ownership
Hayato-2, identified internationally as KSAT-2 and K-SAT-2, is a spacecraft wholly owned and operated by Kagoshima University. The university, established in 1949 and headquartered in Kōrimoto, Japan, served as both the primary manufacturer and the operator. This dual role highlights the satellite's function as an educational and research tool for the institution.

### Technical Specifications
The spacecraft is classified as a **CubeSat**, a specific type of miniaturized satellite composed of one or more 10cm-sided cubic modules (Units). Its primary operational classification is that of a **technology demonstration spacecraft**, meaning its mission objective is to validate new technologies, materials, or orbital maneuvers in a space environment.

### Mission History
The satellite was assigned the COSPAR ID **2014-009G** and the NSSDCA ID **2014-009G**. It was launched on **February 27, 2014**, precisely at **18:37**. The launch was executed from the **Yoshinobu Launch Complex Launch Pad 1**. The launch vehicle used to deploy Hayato-2 was the **H-IIA**, a Japanese expendable medium-lift launch vehicle, specifically flying in the **H-IIA-23** configuration. This event is recorded as a "rocket launch" significant event in the satellite's operational timeline.
