摘要

Prices for launching commercial satellites to geostationary orbit have dropped in the past decade and show signs of continuing the trend, a study backed by Ariane-space with participation by International Launch Services (ILS) finds.rnMeasured by kilograms-to-orbit, and adjusted for inflation, analysis by The Tauri Group finds a 34% drop in launch costs from 1999 to 2008.
