Today NASA pursues technical innovations and scientific discoveries to advance human exploration of space. To prepare for these complex missions, a vast amount of planning, testing, and technology development must be accomplished. Yet, forecasting how that planning will translate into everyday operations in space is difficult while still on Earth. To help prepare for the real-life challenges of space exploration, NASA relies on Earth-based missions that are similar, or analogous, to space.
These are called analog missions or field activities set in remote locations with extreme characteristics that resemble the challenges of a space mission. NASA conducts these missions in extreme environments around the globe to test technologies and systems and to help guide the future direction of human exploration of the solar system. This report profiles the NASA active analog missions, with highlights and successes from the last few years.
