RE: Tentative launch schedule of ISRO

INSAT-3DR satellite has a technical issue. Launch postponed 10 days, so NET September 8.


GSLV launch likely to be delayed.


SHAR: As per sources GSLV launch due for Aug 29 is likely to be delayed. Launcher-satellite integration tests are going on. A pyrocutter is used to deploy solar panels in the satellites. The pyrocutter on INSAT-3DR did not meet the standards. They have decided to replace the pyrocutter. Spares are available. Scientists are studying whether to use a spare or to make a new one. GSLV launch will be delayed by three days if they use a spare pyrocutter, it could be delayed by a week if they decide to use a new pyrocutter.


Launch date was not agreed upon in the MRR.


MRR occured at Wednesday evening. They discussed the problems noticed in the solar panels. For this reason launch date was not confirmed. Another review meet will happen on thursday.

Good to see that fault detected at the ground

RE: Tentative launch schedule of ISRO

Mr. Kiran Kumar said September 8 for GSLV-F05 launch & September 28 for PSLV C35. So, after last year's historic 2 launch in a month (August,2015) we will again see 2 launch in a month :clap :clap :clap 
ISRO actually tried to repeat it on March,2016 but they narrowly miss the target. Hoping for best this time.

1st post updated accordingly.

Successful Flight Testing of ISRO's Scramjet Engine Technology Demonstrator

The first experimental mission of ISRO’s Scramjet Engine towards the realisation of an Air Breathing Propulsion System was successfully conducted today (August 28, 2016) from Satish Dhawan Space Centre SHAR, Sriharikota.

After a smooth countdown of 12 hours, the solid rocket booster carrying the Scramjet Engines, lifted off at 0600 hrs (6:00 am) IST.  The important flight events, namely, burn out of booster rocket stage, ignition of second stage solid rocket, functioning of Scramjet engines for 5 seconds followed by burn out of the second stage took place exactly as planned.

After a flight of about 300 seconds, the vehicle touched down in the Bay of Bengal, approximately 320 km from Sriharikota. The vehicle was successfully tracked during its flight from the ground stations at Sriharikota.

With this flight, critical technologies such as ignition of air breathing engines at supersonic speed, holding the flame at supersonic speed, air intake mechanism and fuel injection systems have been successfully demonstrated.

The Scramjet engine designed by ISRO uses Hydrogen as fuel and the Oxygen from the atmospheric air as the oxidiser. Today’s test was the maiden short duration experimental test of ISRO’s Scramjet engine with a hypersonic flight at Mach 6. ISRO’s Advanced Technology Vehicle (ATV), which is an advanced sounding rocket, was the solid rocket booster used for today’s test of Scramjet engines at supersonic conditions.  ATV carrying Scramjet engines weighed 3277 kg at lift-off.

ATV is a two stage spin stabilised launcher with identical solid motors (based on Rohini RH560 sounding rocket) as the first as well as the second stage (booster and sustainer). The twin Scramjet engines were mounted on the back of the second stage. Once the second stage reached the desired conditions for engine “Start-up”, necessary actions were initiated to ignite the Scramjet engines and they functioned for about 5 seconds. Today’s ATV flight operations were based on a pre-programmed sequence.

Some of the technological challenges handled by ISRO during the development of Scramjet engine include the design and development of Hypersonic engine air intake, the supersonic combustor, development of materials withstanding very high temperatures, computational tools to simulate hypersonic flow, ensuring performance and operability of the engine across a wide range of flight speeds, proper thermal management and ground testing of the engines.

India is the fourth country to demonstrate the flight testing of Scramjet Engine. The successful technology demonstration of air-breathing Scramjet engines in flight by ISRO today is a modest yet important milestone in its endeavour to design and develop advanced air breathing engines including engines for ISRO’s future space transportation system.

RE: Tentative launch schedule of ISRO

The operationalisation of India's heavier rocket Geosynchronous Satellite Launch Vehicle Mk II (GSLV-Mk II) opens up more launch service revenue opportunity, said a top official of Antrix Corporation Ltd.

"The GSLV rocket will operate in a different satellite launch segment. We are looking at various avenues to earn foreign exchange using this rocket," Rakesh said.

Adding to this, Indian Space Research Organisation (ISRO) Chairman

A.S.Kiran Kumar said: "Antrix is also looking at launching small satellites in low orbits. Several small satellites can be accommodated in one GSLV."

The first apogee raise maneuver of INSAT-3DR has been successfully carried out by LAM Engine firing for 2935sec from 08:39hrs IST on September 09, 2016.
Orbit Determination results from this LAM firing are:
apogee X perigee height was changed to 35882 km X 7001 km. Inclination is 9.02 deg. Orbital period is 12hr 49min.
