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.
