IRS-1E was an Earth observation mission launched under the National Natural Resources Management System (NNRMS) programme by Indian Space Research Organisation (ISRO). Sometimes written IRS-P1. The objective of the mission was to develop Earth imagery using instruments carried on board. Due to a malfunction of the launch vehicle, the satellite deviated from its path and plunged into the Indian Ocean.
