Ocean and Land Observation Data From Sentinel-3B
The main mission of the recently launched Sentinel-3B is to provide quality ocean and land monitoring. As part of the Copernicus program, GIS data and imagery will be made freely available.
High Altitude Pseudo-Satellites
High altitude pseudo-satellites (HAPS) are systems or platforms that usually float or operate for long periods, sometimes for months, at about 20 km above the Earth’s surface and can be potentially used to complement earth observation satellites.
Hurricanes, Sea Salt, Dust, and Smoke
This visualization from the Global Modeling and Assimilation Office (GMAO) at NASA's Goddard Space Flight Center shows how particles flow around the Earth's atmosphere.
The Rise of Femtosatellites
Femtosatellites, very small-scale satellites (weighing less than 100 grams / 0.22 lbs), have developed over the last fifteen years thanks to advances in nanotechnology.
