There have been a total of seven failed launches, of which five have been during experimental/ developmental phase whereas two were operational missions. Reasons of the failed launches are as given below:
Sl. Launch Satellite Year Remarks
No. Vehicle

1. SLV-3 E1 RTP Aug 1979 # Experimental flight of SLV-3
# Failure of second
stage control system
2. ASLV-D1 SROSS-1 Mar 1987 # Developmental flight of ASLV
# Failure due to
Non-ignition of
first stage
3. ASLV-D2 SROSS-2 Jul 1988 # Developmental flight of ASLV
# Failure due to loss of
control during transition
from strap-on to first stage.
4. PSLV-D1 IRS-1E Sep 1993 # Developmental flight of PSLV
# Failure during third stage
of flight due to on-board software
5. GSLV-F02 INSAT-4C Jul 2006 # Operational flight of GSLV
# Failure due to malfunctioning
of one of the liquid strap-on
motor (L40) of the first stage.
6. GSLV-D3 GSAT-4 Apr 2010 # Developmental flight of GSLV
# Failure due to anomalous stoppage
of Fuel Booster Turbo Pump (FBTP)
of Indigenous Cryogenic Upper
Stage
7. GSLV-F06 GSAT-5P Dec 2010 # Operational flight of GSLV
# Failure due to untimely and
inadvertent snapping of group of
connectors located at the bottom
portion of the Russian Cryogenic Stage

(b)&(c) Yes, Sir. On April 20, 2011, India’s Polar Satellite Launch Vehicle PSLV-C16, successfully launched RESOURCESAT-2 satellite. The data from this satellite is planned to be used for a host of applications and services like agricultural monitoring, natural resources management, disaster management support as well as infrastructure planning.

(d)&(e) Yes, Sir. During the current financial year, ISRO is planning to launch two more national satellites using Polar Satellite Launch Vehicle (PSLV). This includes launch of MEGHA-TROPIQUES an Indo- French joint satellite mission on-board PSLV-C18 and RISAT-1, a Radar Imaging satellite on-board PSLV-C19.
