N2YO.com is a web-based service that provides real time tracking and pass predictions for Earth orbiting satellites, including the International Space Station. It features an alerting system, orbital paths and footprints, and powers other websites' satellite tracking pages.
The infrared window is a region of the infrared spectrum where terrestrial thermal radiation is not strongly absorbed by atmospheric gases. It plays a key role in the atmospheric greenhouse effect and the habitability of Earth. Learn how it works, what factors affect it, and what human activities threaten it.
A comprehensive list of Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the Earth. The list covers public domain and private domain satellites, their status, agency, launch date, and description.
GOES-16 is the first of the GOES-R series of satellites operated by NASA and NOAA, providing high-resolution imagery of the Earth and space weather. It launched in 2016 and operates in the GOES East position at 75.2°W, covering the Americas.
An atmospheric window is a region of the electromagnetic spectrum that can pass through the atmosphere of Earth. Learn about the optical, infrared and radio windows, their role in Earth's energy budget, and their applications in astronomy, remote sensing and telecommunications.
ICESat-2 is a NASA satellite launched in 2018 to measure ice sheet mass balance, sea ice thickness, and land topography using a space-based lidar. It orbits Earth at 496 km altitude and fires six laser beams to collect elevation data every 70 cm along its ground track.
Sentinel-2 is a Copernicus Programme that acquires optical imagery at high spatial resolution over land and coastal waters. The mission has two satellites, Sentinel-2A and Sentinel-2B, each with a Multi-Spectral Instrument (MSI) that has 13 spectral channels in the visible, near infrared, and short wave infrared part of the spectrum.
Eric Biggs walks his horse on Saturn Boulevard where it passes over the Tijuana River, a spot frequently traversed by local residents. "Look, take a deep breath" is written in chalk on the asphalt ...
