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 mission is a dedicated rideshare flight by SpaceX, scheduled to launch dozens of small satellites into a sun-synchronous orbit as part of SpaceX’s SmallSat Rideshare Program. It will deploy 42 satellites for various international clients, including those from government space agencies, commercial companies, and academic institutions. Exolaunch, a key partner in this mission, is responsible for integrating and deploying many of these satellites using their advanced EXOpod Nova containerized deployers and CarboNIX ring-based separation systems.

The Arctic Satellite Broadband Mission (ASBM) aims to provide reliable broadband communications in the challenging Arctic region. This mission, a collaboration between Space Norway, the U.S. Space Force, and Northrop Grumman, involves two satellites equipped with multiple payloads for both military and commercial use. Notably, it marks the first time a U.S. military payload, the Enhanced Polar System-Recapitalization (EPS-R), is hosted on a non-U.S. satellite. These satellites will operate in a highly elliptical orbit, enabling coverage over the Arctic, an area traditionally underserved by other satellite systems.
