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 381 published reports.
Orbital Period: Meaning, Formula and Satellite Examples
Orbital period measures how long one orbit takes. Discover why higher satellites orbit more slowly, how to calculate a period and why an orbit is not the same as a visible pass.
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.
How Many Satellites Reentered This Year? 2026 by the Numbers
Orbital Radar records 673 satellite and payload re-entries in 2026 so far, within 1,119 atmospheric returns across all object types.
How Long Does It Take to Get to Mars?
Getting to Mars usually takes seven to nine months. The journey depends on where both planets will be at arrival, not simply how far apart they are at launch.
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.
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.
Real-Time Satellite Maneuver Tracking with Orbital Radar
Discover how Orbital Radar's Maneuver Tracker provides real-time insights into satellite maneuvers, enhancing space situational awareness.
Space Tourism Cost: Prices, Providers and Who Can Go
Space tourism costs hundreds of thousands of dollars for suborbital trips and tens of millions for orbital stays. The price depends on the flight, provider and package.
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.
Why Do Rockets Launch From Florida?
Florida combines an eastward boost from Earth's rotation with open Atlantic launch corridors and decades of infrastructure. But the best launch site depends on the mission.
How Long Does It Take to Get to the Moon?
Reaching the Moon can take about three days or several months. The difference lies in the route, the fuel budget and whether a spacecraft must land, orbit or simply fly past.
What Happens to Your Body in Space? The Human Effects
Spaceflight changes how bones, muscles, circulation and eyesight work. Explore the risks of long ISS stays, the countermeasures crews use and what recovery involves.
