Space News Mission Log — Satellite Launches, Orbital Events & Analysis
Daily space news, satellite launch reports, orbital debris analysis and weekly roundups — grounded in live tracking data from our network monitoring 267 published reports.
Space Sustainability: Ensuring the Future of Orbital Operations
Space sustainability involves managing the growing number of satellites and debris to ensure long-term usability of Earth's orbits.
How Many Satellites in Orbit? Counts, Types and Tracking
Earth has 15,870 active satellites, but the wider catalogue includes debris and inactive spacecraft. Here is what the counts mean and how to explore them.
How Often Do Satellites Maneuver? What Our Detector Sees
Orbital Radar logged 45,196 orbit-change events over the past month. Explore what those detections reveal about satellite activity—and why they are not a count of thruster firings.
Graveyard Orbits: The Final Resting Place for Satellites
Graveyard orbits are designated areas where decommissioned satellites are moved to prevent space debris and ensure safer operations.
Medium Earth Orbit: Understanding Its Role in Satellite Operations
Medium Earth Orbit (MEO) is a region of space where satellites orbit at altitudes between 2,000 and 35,786 km, crucial for navigation and communications.
How Many Starlink Satellites Fall Each Day?
1.5 Starlink satellites re-enter Earth's atmosphere each day, according to Orbital Radar data. Explore the reasons behind these controlled re-entries.
NASA vs ESA vs CNSA: How the Space Agencies Compare
NASA, ESA and CNSA represent different ways of organising space exploration. Their budgets, responsibilities and partnerships matter more than a simple ranking.
Space Agencies List: Who Runs the World's Space Programmes?
NASA, ESA and CNSA are part of a much wider network of space organisations. Explore who runs national programmes, how responsibilities differ and where private companies fit.
How Solar Cycles Affect Satellite Operations
Solar cycles influence satellite operations by affecting space weather, which can disrupt communications and increase orbital decay.
Hohmann Transfer Orbit: How the Two-Burn Route Works
A Hohmann transfer connects circular orbits with two engine burns. Discover how it works, what makes it economical and why it is not always the cheapest route.
Low Earth Orbit: Why Space Is Busiest Below 2,000 km
Low Earth orbit hosts space stations, broadband constellations and Earth-observation missions. Explore how it works, why it is crowded and what keeps satellites flying safely.
How Are Satellites Tested Before Launch?
Satellites face simulated launch loads and space conditions before flight. Thermal vacuum, vibration and acoustic tests expose faults that could otherwise end a mission.
