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 400 published reports.
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.
Understanding the Space Fence: Tracking Earth's Orbital Objects
The Space Fence radar system tracks over 28,000 objects in Earth's orbit, from satellites to debris, ensuring space safety.
Understanding Polar Orbits: Key Facts and Uses
Polar orbits pass over the Earth's poles, allowing satellites to scan the entire surface. They are crucial for Earth observation missions.
Understanding Rocket Body Debris in Earth's Orbit
Rocket body debris refers to the remnants of launch vehicles left in orbit, contributing significantly to space debris and posing collision risks.
Understanding Satellite Orbits: LEO, MEO, GEO and Beyond
Satellite orbits, including LEO, MEO, and GEO, define how satellites move and function in space. Each orbit serves unique purposes.
Understanding Orbital Decay: Why Satellites Fall to Earth
Orbital decay is the gradual reduction of a satellite's orbit due to atmospheric drag and gravitational forces, leading to eventual reentry.
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.
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.
Delta-V Explained: The Currency of Spaceflight
Delta-v is the change in velocity needed for space manoeuvres, crucial in mission planning and satellite operations.
What Happens If Two Satellites Collide?
A satellite collision can leave fragments circling Earth long after the spacecraft are destroyed. Their altitude helps determine how long the danger lasts.
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.
Understanding Apogee and Perigee in Satellite Orbits
Apogee and perigee refer to the highest and lowest points in an orbit, crucial for understanding satellite paths and operations.
