  Scientists of the Indian Space Research Organisation (Isro) have been gearing up for the launch of the Geo-synchronous Satellite Launch Vehicle (GSLV-F05) carrying 2,200 kg of meteorological satellite INSAT-3DR on board most likely on September 10 this year. This is one among the four rocket launches planned by Isro before the end of this year.

  Earlier Mr Krishnan had said the Indian weather satellite will be launched on August 28 which has now been postponed to September 8.
  
  Queried about the change in launch plan Krishnan said: "While carrying out the tests there was a technical issue found with a satellite component. It has been sorted out now and hence the delay."
  
  He said the GSLV rocket that would carry the weather satellite INSAT-3DR is fully assembled.
  
  The weather satellite will be mounted on to the rocket in three to four days.

  THIRUVANANTHAPURAM: Buoyed by the success of the ISRO's Sramjet engine test on Sunday, Scientists of Vikram Sarabhai Space Centre (VSSC) and Liquid Propulsion Systems Centre (LPSC) have begun preparations for the launch of GSLV Mark II scheduled for Sep 8.
  
  "Now, the preparations are on for the GSLV Mark II mission on Sept 8 for the launch of INSAT-3DR, an Indian satellite for weather forecast, search and rescue information. It will be the second flight using the indigenously developed cryogenic engine after it was successfully used for the first time to launch GSLV-D5 in 2014," VSSC director K Sivan told TOI.
  
  The indigenous cryogenic engine to be used for GSLV Mark II on Sept 8 will be similar to the one used in GSLV-D5 launch two years back, the scientists said.

• There were conflicting reports in many newspapers about if INSAT 3DR is a 2061 Kg or 2200 Kg Satellite.
  But all the misinformation is laid to rest by the ISRO Website INSAT 3DR page.
  
  It is a 2211 Kg Satellite, an increase of odd 100 kg than the satellite launched by GSLV MK II last year.

  INSAT-3DR has a lift-off mass of 2211 kg, which includes about 1255 kg of propellant. The propellant carried by INSAT-3DR is mainly required to raise the satellite from the Geosynchronous Transfer Orbit (GTO) to its final Geostationary Orbit and to maintain the satellite in its orbital slot during its life. INSAT-3DR is based on ISRO's two Tonne Class platform (I-2K bus) employing light-weight structural elements like Carbon Fibre Reinforced Plastic (CFRP). The satellite has a solar array generating 1700 Watts of power.

• Is there any specific reason why the GSLV is moved to the pad a full 5-6 days before the launch ?

  Isn't that the usual time frame, approx?
  
  EDIT: Feeling a bit jittery though, in light of the SpaceX incident yesterday.. Space is hard...

  India should think alternative ways of propelling the satellite so as to reduce flight mass. Japan has utilized eon propulsion system. Indian too can think of in such direction for cruising the bird on space.

• GSAT 4 launched in 2010 had ion propulsion, but it failed to reach orbit. ISRO is working on using ion propulsion for its future satellites.

• Information about ISRO's ion thrusters can be found here: https://forum.nasaspaceflight.com/index.php?topic=33770.0
  
  GSAT-19E would be having ion thrusters for satellite station keeping. It would be launched aboard LVM3-D1 by the end of this year.

  It seems an increase of odd 100 kg payload capacity has an effect in vehicle's guidance error margin - targeted inclination of 20.61° for GSLV F5  Vs  19.3° inclination achieved by GSLV D5/GSAT-14 mission. If you see past GSLV missions you can clearly observe gradual increase of inclination with increase of vehicle's payload capacity .

  IIRC , PSLV coutdown = 48 hrs.
  
  Count down of GSLV (~29 hrs ) << PSLV count down (~48 hrs).
  
  Is this because the GSLV has one less stage ?
