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 123 published reports.
Satellite Ground Stations: The Backbone of Space Communication
Satellite ground stations are vital for receiving data from and sending commands to satellites, enabling global communication and navigation.
TDRS: NASA's Data Relay Network in GEO
The Tracking and Data Relay Satellite (TDRS) system is a network of communications satellites operated by NASA to support space missions. This network provides continuous high-data-rate communication links between spacecraft in low Earth orbit (LEO) and ground stations on Earth.
SpaceX AI Satellites: Pioneering Autonomous Space Operations
SpaceX's AI satellites are revolutionising autonomous space operations by enhancing satellite communication and navigation capabilities.
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.
Understanding Satellite Frequency Bands: A Comprehensive Guide
Satellite frequency bands are specific ranges of radio frequencies used for communication between satellites and Earth. Learn about their significance and applications.
Understanding Geostationary Orbital Slots and Their Importance
Geostationary orbital slots are specific positions in Earth's orbit where satellites remain fixed relative to a point on the equator, crucial for communications.
Satellite Radio Propagation: Finding the Best Contact Times
A satellite’s position is only part of a successful radio link. Learn how to interpret propagation heatmaps alongside pass predictions, space weather and your station’s limits.
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 Solar Cycles Affect Satellite Operations
Solar cycles influence satellite operations by affecting space weather, which can disrupt communications and increase orbital decay.
GOES-19: the weather watch at 35,786 kilometres
Operating as GOES East since April 2025, GOES-19 watches Atlantic hurricanes, American thunderstorms and solar activity from a near-fixed position above the equator.
Parts of a Satellite: Systems That Keep It Working
Discover the key components and systems inside a satellite that ensure its operation in space, including power, thermal control, and communication.
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.
