From Blue Dot to ISS Commander: A Legacy of Orbital Leadership
Alexander Gerst made history during his 2018 Horizons mission when he became the first German astronaut—and only the second European—to command the International Space Station (ISS). His orbital trajectory began in 2014 with the Blue Dot mission, where his scientific rigor and engaging public outreach brought space science directly to millions on Earth.
As a trained geophysicist and volcanologist, Gerst logged hundreds of scientific experiments ranging from human physiology to material science in microgravity. Across his two long-duration stays, he conducted six spacewalks. His technical competence and operational leadership under pressure earned him key leadership roles within ESA's astronaut management structure.
Earth Observation and Scientific Impact: Bridging Space and Climate Research
Beyond engineering feats and spacewalks, Gerst's missions placed a critical emphasis on Earth observation and climate stewardship. Using high-resolution photography and orbital sensor platforms, he actively documented extreme weather events, glacier retreats, and forest destruction to highlight global climate change.
His research contributions extend into cutting-edge biotechnology and physical sciences. Key achievements from his orbital tenure include:
- Advanced Life Support Testing: Evaluating closed-loop biological systems critical for multi-year deep-space missions.
- Robotic Tele-Operation: Testing real-time ground control systems to operate planetary rovers on simulated surfaces from orbit.
- Geophysical Sensing: Monitoring Earth's dynamic systems to refine climate models used by international research bodies.

Target Moon: Preparing Europe’s Astronaut Corps for the Artemis Era
As international focus shifts from low-Earth orbit toward lunar exploration, Gerst plays an indispensable role in preparing Europe's astronaut corps for lunar surface operations. ESA’s collaboration with NASA on the Artemis program includes providing the European Service Module (ESM) for the Orion spacecraft and critical habitation modules for the lunar Gateway station.
Gerst is heavily involved in field geology training and lunar analogue simulations, utilizing state-of-the-art facilities such as ESA’s LUNA facility in Cologne, Germany. By teaching astronauts how to conduct field science in lunar-like terrain, he is ensuring European crew members are technically equipped for surface operations. As humanity approaches a permanent presence on the Moon, Gerst’s operational expertise bridges the gap between ISS operations and deep-space exploration.
