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.
Gaia: ESA’s billion-star surveyor beyond Earth
Gaia stopped observing in January 2025, but its measurements of stellar positions, distances and motions remain a foundation for mapping the Milky Way.
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.
How Crowded Is Low Earth Orbit? Satellites by Altitude
Low Earth orbit is crowded unevenly: payloads dominate some altitude bands, while debris fills others. Explore the concentrations and what they mean for collision risk.
Terra: NASA’s long view of a changing Earth
Launched in December 1999, Terra helped establish a continuous, planet-wide record of Earth’s atmosphere, land and oceans. Its legacy rests on observing those connected systems together.
Landsat 9: Earth Observation from 705 km
Landsat 9 is the latest satellite in the long-running Landsat programme, a joint initiative by NASA and the United States Geological Survey (USGS) to monitor Earth's surface. Launched on 27 September 2021, Landsat 9 continues a legacy of Earth observation that began in 1972 with the launch of Landsa
Landsat Satellites: Comprehensive Guide to Earth Imaging
Landsat satellites provide critical Earth imagery for monitoring natural resources and environmental changes, revolutionising remote sensing.
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.
Tracking Near-Earth Asteroids: A Comprehensive Guide
The Near-Earth Object Database provides live tracking of asteroid orbits, close approaches, and impact risks, offering crucial insights into space safety.
Satellite Imagery Explained: How Earth Observation Works
Satellite imagery is the process of capturing images of Earth from orbiting satellites, providing vital data for environmental monitoring, mapping, and more.
Unveiling Earth's Shadow: A 22-Year Lunar Eclipse Journey
A composite image from 22 years of lunar eclipses reveals Earth's shadow, offering insights into our planet's orbit and atmospheric effects.
Auroral Ovals: Earth's Dazzling Light Show from Space
Auroral ovals, visible only from space, encircle Earth's magnetic poles in a stunning display of light. Discover the science behind this phenomenon.
