Madeleine Gregory Landsat Project Science Support Apr 15, 2026 In the more than five decades of the Landsat program, there have been many visionaries who have changed the course of remote sensing history. One such figure is Alexander Goetz, a physicist and planetary scientist who pioneered imaging spectrometry from space. Goetz was part of the Landsat Program from the very beginning, working as a principal investigator for Landsats 1 and 2. Years later, he returned to the program as a member of the first formal Landsat Science Team on Landsat 7. This diverse group of researchers, technologists, and calibration and applications specialists helped advance Landsat science goals, refined algorithms, and supported on-the-ground calibration. Crucially, the team advised on the creation of the long-term acquisition plan (LTAP), which ensured consistent global, seasonal coverage of Landsat data.…
