Preparatory work for the launch of the geosynchronous launch vehicle (GSLV) slated
for the evening of 1 September, 2007, is going briskly at the Satish Dhawan Space
Centre, Sriharikota, Andhra Pradesh.
rocket carrying communication satellite Insat 4CR weighing 2,130 kg will blast
off from the second launch pad.
success of the forthcoming launch is crucial for the country as it is ISRO''s second
attempt to launch an Insat satellite from Indian soil using an Indian rocket.
launch vehicle''s configuration is identical to that of
GSLV F02 that failed in July 2006 owing to manufacturing
error. (See: Inadvertent
manufacturing error cost nation Rs256 crore and ISRO
forced to destroy GSLV in mid air). The rocket
carried Insat 4C weighing 2,168 kg - the heaviest satellite
carried by the GSLV.
ISRO has reduced the weight of the Insat 4CR by 38 kg now.
following this will be the launch of polar satellite launch vehicle (PSLV) sometime
during the middle of September to put an Israeli satellite Polaris weighing around
300 kg into orbit. The vehicle is configured as ''core alone'' that is without PSLV''s
standard six strap on motors.
44-metre high PSLV weighs 295 tonnes. The core-alone version sheds about 65 tonnes,
and weighs 230 tonnes. The version is also lighter on ISRO''s purse as it costs
around Rs70 crore to build, cheaper by around Rs15 crore vis-à-vis the
fully loaded PSLV.
had earlier flown a `core alone'' PSLV this April with Agile a 352 kg Italian satellite.
year-end will see another PSLV flight carrying a remote sensing satellite- Oceansat
or Cartosat. The launch vehicle will also carry a cluster of six micro-satellites
from Canada piggyback on the same launch. Together, these six micro-satellites
will weigh only 26 kg.
