4th International Workshop on Space-based Lidar Remote Sensing (SLRS) Techniques and Emerging Technologies
November 2 - 7, 2025
Kimpton Armory Hotel in Bozeman, Montana

SLRS offers a platform for scientists and technologists from various countries, government agencies, industry, and universities to meet and discuss critical topics related to current and planned space lidar missions, techniques, and emerging technologies
Additionally, it will serve as an opportunity to address challenges and common issues while exploring ways to enhance collaboration among space agencies and organizations. This collaboration is essential for improving future active space-based remote sensing measurements.
Workshop goals:
- Evaluate the scientific requirements for space-based lidar measurements, instrument synergies, and the readiness of lidar techniques to fulfill these requirements.
- Introduce upcoming space-based lidar missions and present / discuss results from existing and past lidar space-based missions.
- Explore the challenges and future directions in research and technology development.
- Explore strategies to reduce risks and costs for space-based lidar instruments while enhancing mission longevity.
- Identify synergies and ways to enhance space lidar missions through international cooperation among various space agencies and organizations.
- Document the results in the completion and update of the white paper from prior workshop.
The topics planned for presentations and discussion:
- Advances in space-based lidar techniques and methodologies.
- Science highlights, observational approaches, and technologies used.
- Challenges experienced and lessons-learned in space lidar missions to date and discussion of approaches to overcome them.
- Explore new space Earth Observation lidar missions, which include monitoring of: Topography, Cryosphere , Biomass, Greenhouse and Trace Gases, Clouds, Aerosols, Oceans and Wind.
- Explore recent advancements in interferometric lidar technology, focusing on innovations in optical design, signal processing, and applications in wind profiling, aerosol characterization, and atmospheric turbulence detection.
- Exploration Lidars: Entry, Decent and Precision Landing, as well as Hazard Avoidance for Mars & Lunar landers missions.
- Results and plans for simulations, airborne experiments and demonstrations as precursors for space missions.
- Explore the reliability of space-based LiDAR systems, focusing on design robustness, redundancy strategies, and fault-tolerant technologies to enhance mission success in harsh space environments.
- New and emerging space lidar technologies, particularly in lasers, optics, electronics and detectors as well as space lidar reliability and influencing factors, such as effects of the space environment (thermal, vibration, contamination, and radiation effects).
