## FAQs
### Q: When was Diwata-1 launched and deployed?
A: Diwata-1 launched on March 23, 2016, and was deployed from the ISS on April 27, 2016.

### Q: Who built Diwata-1?
A: It was collaboratively developed by the Philippines' Department of Science and Technology, University of the Philippines, and Japan's Hokkaido University and Tohoku University.

### Q: What was the primary purpose of Diwata-1?
A: The satellite was designed for Earth observation, focusing on disaster risk reduction, environmental monitoring, and agricultural resource management.

## Why It Matters
Diwata-1 represents a significant advancement in the Philippines' space technology capabilities, demonstrating the country's entry into the global space sector. As the nation's first microsatellite, it provided critical high-resolution imagery for applications such as disaster response, environmental monitoring, and agricultural planning. The project fostered international collaboration, particularly with Japanese academic institutions, and paved the way for subsequent Philippine satellite projects like Diwata-2. Its successful deployment from the ISS highlighted the feasibility of low-cost, small-satellite solutions for developing countries, addressing needs such as typhoon tracking and land-use mapping.

## Notable For
- First microsatellite deployed by the Philippines.
- Collaborative project between Philippine and Japanese universities.
- Carried a hyperspectral imager and medium-resolution camera for detailed Earth observation.
- Deployed from the ISS, leveraging existing infrastructure for cost-effective deployment.
- Part of a broader initiative to establish a Philippine space program.

## Body
### Development
Diwata-1 was developed under the PHL-Microsat program, a collaboration between the Department of Science and Technology (DOST), University of the Philippines Diliman, Hokkaido University, and Tohoku University. The satellite was designed for a mission lifespan of approximately one year.

### Launch and Deployment
- **Launch Vehicle**: Atlas V 401, operated by United Launch Alliance.
- **Launch Site**: Cape Canaveral Space Launch Complex 41.
- **Deployment Mechanism**: Released from the Kibo experiment module on the ISS using a JEM Small Satellite Orbital Deployer (J-SSOD).

### Mission and Instruments
- **Instruments**:
  - Hyperspectral Imager (HI) for environmental monitoring.
  - Medium-Resolution Camera (MRC) for disaster response.
  - Low-Energy X-ray Imaging Spectrometer (LEXI) for space weather studies.
- **Applications**: Data collected supported agricultural optimization, maritime surveillance, and natural disaster mitigation efforts.

### Legacy
Diwata-1's success led to the development of Diwata-2 (launched in 2017) and contributed to the establishment of the Philippine Space Agency (PhilSA) in 2019. The satellite's imagery was used by government agencies for typhoon aftermath assessments and urban planning.
