EPOXI Earth Observations: Raw HRIV Images for Exoplanet Analogs

NASA's Deep Impact spacecraft captured raw narrow-band images of Earth from space during three 24-hour periods in 2008. The High Resolution Visible CCD instrument collected data at wavelengths from 350 to 950 nm, with a unique observation of the Moon transiting Earth in May. These images were acquired to characterize Earth as an analog for extrasolar planets.

Use Cases

• Analyzing Earth's spectral signatures at specific wavelengths (350, 450, 550, 650, 750, 850, 950 nm) for exoplanet comparison
• Studying temporal changes in Earth's appearance over 24-hour observation periods
• Modeling planetary disk observations based on the unique Moon transit event captured in May 2008
• Developing image processing pipelines for raw, narrow-band filter data from space-based instruments

Strengths

• Data originates from NASA's EPOXI mission, a recognized scientific spacecraft
• Observations cover three distinct 24-hour periods in March, May, and June 2008
• Includes a unique celestial event: the Moon transiting Earth as seen from the spacecraft

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and file formats are unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
