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 12 published reports.
OneWeb Gen 2: the next broadband constellation
OneWeb’s next generation is intended to expand a broadband network built around business, government and transport connections. Its significance lies as much in replacing ageing spacecraft and integrating ground networks as in adding satellites.
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.
Satellite Licensing and Spectrum: A Complete Explainer
Satellite licensing is the process of obtaining permission to launch and operate a satellite, ensuring compliance with international regulations and spectrum allocation.
How Do Radar Satellites Work? SAR Explained
Radar satellites illuminate Earth with microwaves rather than waiting for sunlight. Learn how their echoes become images, what SAR reveals and where its limits lie.
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.
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.
Aqua: tracking Earth's water cycle since 2002
NASA's Aqua satellite brought clouds, rainfall, ocean temperatures and atmospheric moisture into a single observing mission, building a record of how water moves through Earth's climate system.
Types of Satellite Orbits: LEO, MEO, GEO and Beyond
Altitude is only part of an orbit’s story. Explore how height, tilt and shape determine what satellites can see, how they communicate and how long they remain in space.
How Often Do Satellites Almost Collide? Near Misses in Orbit
Orbital Radar recorded 536 approaches within 1 km in the latest 30 days. Its conjunction history reveals a longer-term rise, but proximity alone does not establish collision risk.
How Do Satellites Get Power? Solar, Batteries and Nuclear
Most satellites turn sunlight into electricity and use batteries in darkness. Explore how spacecraft generate, store and ration power, from Earth orbit to deep space.
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.
Amazon Kuiper: Comprehensive Guide to Amazon's Satellite Internet
Amazon Kuiper is a satellite internet constellation designed to provide global broadband coverage. Discover its mission, technology, and potential impact.
