NASA's LADEE Mission

Take the Plunge: LADEE Impact Challenge

The LADEE spacecraft is gradually lowering its orbital altitude over the moon and will continue to make important science observations before its planned impact into the lunar surface later this month. When will it impact the lunar surface? NASA wants to hear your best guess!

LADEE News and Features

What is LADEE?

NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) - pronounced "laddie" - is a robotic mission that will orbit the moon to gather detailed information about the structure and composition of the thin lunar atmosphere, and determine whether dust is being lofted into the lunar sky. A thorough understanding of these characteristics of our nearest celestial neighbor will help researchers understand other bodies in the solar system, such as large asteroids, Mercury, and the moons of outer planets.

The LADEE spacecraft's modular common spacecraft bus, or body, is an innovative way of transitioning away from custom designs and toward multi-use designs and assembly-line production, which could drastically reduce the cost of spacecraft development, just as the Ford Model T did for automobiles. NASA's Ames Research Center designed, developed, built, and tested the spacecraft and manages mission operations.
