Hyperspectral Eyes in the Sky: How Space-Based Imaging Is Revolutionizing Earth Observation

Hyperspectral Eyes in the Sky: How Space-Based Imaging Is Revolutionizing Earth Observation

NASA’s Hyperion sensor, launched in 2000, captured 220 spectral bands from 400 to 2500 nm at 30 m resolution, enabling material identification by spectral fingerprints. Recent missions include Italy’s PRISMA (2019), Germany’s EnMAP (2022), and Carbon Mapper’s Tanager-1 (2024) for methane and CO2 detection. Commercial constellations like Pixxel and Orbital Sidekick offer higher band counts and finer resolution.

Sky Scanners: How SAR Imaging Satellites Are Redefining Earth Observation

About 75% of Earth is hidden from optical satellites by clouds or darkness at any time. Synthetic Aperture Radar (SAR) satellites like Sentinel-1, RADARSAT, TerraSAR-X, COSMO-SkyMed, ICEYE, and Capella Space provide high-resolution, all-weather, day-and-night imaging. ICEYE and Capella now offer sub-meter resolution and rapid delivery. NASA/ISRO’s NISAR mission is set to launch in 2025 with dual-band SAR.

Satellite Internet FAQ

Satellite Internet FAQ

Traditional GEO satellite internet, such as HughesNet and Viasat, sends data 22,000 miles to orbit, resulting in 600–800 ms latency. Starlink uses low-Earth orbit satellites, offering 50–200 Mbps download and 20–40 ms latency. HughesNet and Viasat impose data caps; Starlink does not. Weather can disrupt service, though Starlink dishes may include heaters to melt snow.
