Our Home Sweet Homeworld

Our home is a terrestrial planet that’s mostly covered by liquid water, unlike our neighboring planets. Earth is affected by the influences of the Moon, Sun, solar wind, meteoroids, asteroids, and its own inhabitants: us.

With its vast oceans, active geology, dynamic atmosphere, and protective magnetic field, Earth has been a relatively safe (and so far the only known) haven for life to evolve and diversify. APL is dedicated to providing the science needed to keep it that way. Through instruments that track clouds and air pollutants, as well as space missions to understand the interaction of the Sun’s solar wind with, and dynamics within, Earth’s magnetosphere and upper atmosphere, APL is providing the tools and insight needed to help preserve the diversity of Earth’s life while helping to forecast space weather, which can disrupt our technology, and better understand the near-Earth space environment.

Missions

APL has designed, built, and operated more than 70 innovative spacecraft over its six decades of spaceflight experience. Click below to learn about some of the missions that made revolutionary discoveries, and spacecraft that will push the boundaries of exploration and investigate outstanding scientific mysteries.

Initiatives

While APL may be known for engaging is space-firsts and building first-of-its-kind spacecraft that deflect asteroids or touch the sun, it also has a deep knowledge base of science and engineering experts who provide critical contributions to critical challenges. Through initiatives like Planetary Defense, Heliophysics and Space Weather, and Cislunar Operations, APL is able to deliver game-changing impacts for civil and national security.

Instruments

Scientists and engineers at APL have designed, built, and operated more than 300 novel space instruments and methods to conduct cutting-edge research and make groundbreaking discoveries.
