About
Petra Rettberg is a distinguished space biologist and astrobiologist whose research sits at the critical intersection of human spaceflight, planetary protection, and astrobiology. Based at the German Aerospace Center (DLR), she has made foundational contributions to understanding both the survivability of humans during long-duration exploratory missions and the international frameworks necessary to safeguard scientific integrity during Mars exploration. Her seminal 2005 work on the HUMEX study (68 citations) systematically examined the biological and physiological challenges astronauts would face on Mars missions, establishing a cornerstone reference for mission planners worldwide. More recently, Rettberg has become a leading voice in planetary protection policy, contributing significantly to COSPAR guidelines and knowledge gap analyses that bridge current robotic exploration with future crewed Mars missions — work that has accumulated nearly 85 citations across just four papers since 2021, reflecting its urgent relevance to the field. Her contributions extend to astronaut training initiatives such as ESA's CAVES program and the development of astrobiology instrumentation. With research spanning policy, biology, and mission science, Rettberg's work is essential reading for anyone preparing to engage seriously with the challenges of human interplanetary exploration.
