Over Five Decades of Unique Earth Science Imaging from Space

A Profoundly Vital Resource of Digital Data Mapping Earth's Systems

Beginning with the Work of 'the MSS', the Multispectral Scanning System

The Multispectral Scanning System

Virginia Tower Norwood decided to quantize the MSS data into 6-bits. Both image data and calibration data (from the onboard internal lamp calibrator) were sent to the ground digitally. Even though the digital MSS data had a small dynamic range (able to show only 64 different radiance values), it could be calibrated, so images could be confidently compared from date-to-date and place-to-place.

The MSS radiometrically-corrected digital data pioneered quantitative satellite remote sensing, taking the science of Earth observation digital, where it has stayed ever since...

Envisioned as an Intergenerational Science Mission

The first land-focused Earth-observation satellite, Landsat 1 (initially called the 'Earth Resources Technology Satellite-1 / ERTS-1) is launched to Earth orbit from Vandenberg, CA.
