This photograph shows Orion in the foreground on flight day 13 of the Artemis 1 mission, Nov. 28, 2022. Earth and the Moon can be seen in the background. On that day, Orion reached its maximum distance from Earth during the Artemis I mission when it was 268,563 miles away from our home planet. Orion has now traveled farther than any other spacecraft built for humans.

Exploration Architecture, Integration, and Science Directorate

Based at NASA’s Johnson Space Center in Houston, Texas, the Exploration Architecture, Integration, and Science (EAIS) Directorate is a unique mix of scientists, engineers, mission planners and architects, and program analysts. We create the plans for sending people back to the Moon and on to Mars. We provide integration and business support to NASA’s exploration programs, which stitch together the pieces that make NASA’s missions possible. Our team curates and studies the world’s most extensive collection of samples collected from the solar system. We map the orbital debris around the Earth to keep our missions safe, and we study the lunar surface to figure out where to land NASA missions. Together we enable exploration and discovery.

Our Purpose

EAIS is dedicated to supporting NASA’s mission to explore, discover, and expand knowledge for the benefit of humanity. We connect science, engineering, and mission and program planning so that NASA can send people back to the Moon and eventually on to Mars. We help NASA’s exploration programs figure out what the missions are, how to plan and execute them, and how to make the most of the science they bring home.

NASA’s Space Launch System (SLS) rocket with the Orion spacecraft aboard is seen atop the mobile launcher at Launch 39B at NASA’s Kennedy Space Center in Florida. Artemis I mission is the first integrated test of the agency’s deep space exploration systems: the Space Launch System rocket, Orion spacecraft, and supporting ground systems. The mission is the first in a series of increasingly complex missions to the Moon. Launch of the uncrewed flight test is targeted for no earlier than Sept. 3 at 2:17 p.m. ET. With Artemis missions, NASA will land the first woman and first person of color on the Moon, using innovative technologies to explore more of the lunar surface than ever before.
