Mars 2020 Mission Objectives

The Mars 2020 mission seeks ancient microbial life, prepares a returnable cache, and collects samples for possible return while exploring Mars geology. It also prepares for human exploration, measures environmental conditions, demonstrates resource utilization, and explores ancient environments for signs of past life. Launching in July 2020, the mission aims to understand Mars' geology, habitability, and biosignatures. Learn more at: https://mars.nasa.gov/mars2020/

  1. Mars 2020 Mission Objectives SEEKING ANCIENT MICROBIAL LIFE • PREPARE A RETURNABLE CACHE • Capability to collect ~40 samples and blanks, 20 in prime mission • Include geologic diversity • Deposit samples on the surface for possible return • PREPARE FOR HUMAN EXPLORATION • Measure temperature, humidity, wind, and dust environment • Demonstrate In Situ Resource Utilization by converting atmospheric CO2 to O2 • GEOLOGIC EXPLORATION • Explore an ancient environment on Mars • Understand processes of formation and alteration • HABITABILITY AND • BIOSIGNATURES • Assess habitability of ancient environment • Seek evidence of past life • Select sampling locations with high biosignature preservation potential

  2.
