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.
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.
Oldest Satellite Still in Orbit: Vanguard 1 and the Top Ten
Vanguard 1 remains the oldest satellite orbiting Earth. Its surviving companions include rocket hardware and early scientific satellites whose orbits explain their longevity.
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 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.
Artemis safety concerns: Orbital Briefing, 23 October 2026
NASA's safety panel raises concerns over Artemis IV and future access to low Earth orbit, while Dragon cargo reaches the ISS and satellite close approaches draw attention.
How Satellite Internet Works: A Comprehensive Guide
Satellite internet connects remote areas by transmitting data between ground stations and satellites in orbit, such as Starlink's network.
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 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.
South Atlantic Anomaly: Why Satellites Glitch
A weak patch in Earth's magnetic shield brings trapped radiation into the paths of low-orbiting spacecraft. Here is why satellites glitch and how operators protect them.
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.
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.
