Planet 03 · Terrestrial ocean world
The only known world with a living ocean.
Earth is the largest rocky planet and the only place known to host life. Liquid surface water, plate tectonics, a protective magnetic field, and a nitrogen-oxygen atmosphere make it unlike every other world we have examined.
World profile
About 78% nitrogen, 21% oxygen, and 1% other gases.
A moving rocky crust with continents, ocean basins, ice, and active plate tectonics.
Global average about 59 °F (15 °C)
One — the Moon
Composition
Field notes
Earth is the only planet known to keep stable liquid water on its surface.
The moving liquid-metal outer core generates the magnetic field that helps shield the atmosphere.
The leading model for the Moon's origin starts with a giant impact into the young Earth.

This is a rideshare mission. The primary satellite, EOS-N1 (codenamed Anvesha), is a hyperspectral imaging satellite developed largely for the DRDO (Defence Research and Development Organisation). It is capable of "seeing" in hundreds of wavelengths to identify materials on the ground—making it a high-priority asset for national security and surveillance.

Launching an Earth observation satellite for the Italian Space Agency (ASI). The satellite will operate in a circular sun-synchronous dawn-dusk orbit with a nominal altitude of 619 km and an inclination of 97.86º. The COSMO-SkyMed second generation (Constellation of Small Satellites for Mediterranean basin observation) or CSG will replace the first generation COSMO-SkyMed system.
