Ground radar vs optical telescopes vs space-based sensors for debris tracking: accuracy and coverage compared

Compares three primary orbital debris tracking approaches: ground-based radar (US Space Surveillance Network tracks 27,000+ objects ≥10 cm), optical telescopes (effective for GEO debris down to 1 m), and emerging space-based sensors (capable of detecting sub-centimeter fragments). Evaluates detection thresholds, catalog accuracy, latency, and cost per tracked object.

LEO vs GEO vs MEO constellations for climate monitoring: orbit trade-offs compared

Compares Low Earth Orbit, Geostationary, and Medium Earth Orbit satellite constellations for climate resilience applications. LEO offers 1–5 m resolution with 90-minute revisit but requires 100+ satellites; GEO provides continuous hemispheric coverage at 1–4 km resolution from a single platform. Breaks down latency, cost-per-pixel, and data throughput trade-offs.

Myth-busting space weather and geomagnetic risk: separating hype from reality

Debunks five common misconceptions about space weather: that extreme storms are too rare to plan for (G4+ events occur 4–6 times per solar cycle), that modern grids are immune (Quebec's 1989 blackout affected 6 million people in 92 seconds), and that only high latitudes face risk (GICs at Kp≥8 affect infrastructure down to 40°N). Provides evidence-based risk framing for infrastructure operators.
