Extravehicular Activity & Human Surface Mobility

NASA’s Extravehicular Activity and Human Surface Mobility Program provides safe, reliable, and effective spacewalking and surface mobility capabilities that allow astronauts to survive and work outside the confines of a base spacecraft in order to explore on and around the Moon. Located within the Advanced Exploration Systems Division at NASA Headquarters and supporting both the Space Operations Mission Directorate and the Exploration Systems Development Mission Directorate, the Extravehicular Activity and Human Surface Mobility Program is comprised of several key elements, including spacewalking capabilities in both low Earth orbit and on the Moon, the Lunar Terrain Vehicle, technology development and partnerships, and pressurized crewed rover systems.

Overview

Providing spacesuit capabilities and surface mobility systems for humanity’s return to the Moon.

NASA’s Extravehicular Activity and Human Surface Mobility Program represents a key cornerstone of NASA’s Artemis program to return humans to the Moon and explore deep space, as well as continuing a critical role supporting the International Space Station and the commercialization of low Earth orbit. It serves as the agency’s program to develop next-generation spacesuits, human-rated rovers (pressurized and unpressurized), and tools, along with all the necessary spacewalking support systems for use in microgravity, on the lunar surface and, eventually, on other planets. The Extravehicular Activity and Human Surface Mobility Program leverages commercial and international partnerships to obtain services related to extravehicular and surface mobility activities. Using commercial partnerships enables NASA to benefit from industry innovations and efficiencies and allows the vendors to offer these services to the private sector, outside of NASA programs. In this way, the program is facilitating the advancement of U.S. industry that actively benefits the economy and American taxpayer.
