IRS-1E

Name:IRS-1E

LaunchDate:20.09.1993

IRS-1E satellite, derived from the engineering model of IRS-1A incorporating a Monocular Electro-Optical Stereo Scanner developed by DLR, Germany, and a LISS-I camera similar to that on IRS-1A, could not be placed into orbit by the PSLV-D1 launched in September 1993.

The mission was not realised due to problems faced by Launch Vehicle. It was the first development flight of PSLV.
