Lineage The Landsat spacecraft series evolved from an experimental program (LS-1 to LS-3) to an operational program (LS-4 and LS-5) as NASA developed and launched considerably improved spacecraft that were placed into lower orbits than the previous Landsat spacecraft and carried improved instrument suites. Following the loss of Landsat-6 during launch in 1993, Landsat-7 was placed on a fast track for launch in 1998, but was ultimately launched on 15 April 1999, providing continuity in medium resolution multi-spectral imagery.
