Landsat-1 to Landsat-3

Mission

The Earthnet Programme: 40 years of evolution and future challenges
ESA's Earthnet Programme provided the initial means to access and exploit Earth Observation data.

blue arrow Mission Overview

The Landsat programme is a joint USGS and NASA-led enterprise for Earth Observation that represents the world's longest running system of satellites for moderate-resolution optical remote sensing for land, coastal areas and shallow waters.

The first Landsat mission was launched in 1972, and was the first Earth observation satellite with the goal to monitor the world's land. It was soon followed by successors, and the series continues to this day.

Landsat 1 to 3 are part of ESA's Third Party Missions Programme, in which ESA has an agreement to distribute data products from the missions.

blue arrow Mission Objectives

The primary mission objective was to monitor Earth resources with two imaging systems and to achieve periodic and complete coverage of the United States via multispectral, high spatial resolution images of solar radiation reflected from the Earth's surface.

blue arrow Instruments

The Multi Spectral Scanner (MSS) instrument was carried aboard the Landsat 1 to 5 missions between 1972 and 2013. The objective of MSS was to provide repetitive daytime acquisition of high-resolution, multispectral data of the Earth's surface on a global basis and to demonstrate that remote sensing from space is a feasible and practical approach to efficient management of the Earth's resources.

The Return-Beam Vidicon (RBV) instrument was carried aboard the Landsat 1 to 3 satellites between 1972 and 1983. It consisted of three co-aligned television cameras, one for each spectral band (band 1: blue-green, band 2: yellow-red, band 3: NIR). RBV measurements of reflected solar radiation were only conducted in daylight.
