Munuswamy Shanthi of SHAR conferred with Nari Shakti Puraskar

Ms Munuswamy Shanthi, a scientist at SHAR, Sriharikota was conferred with Nari Shakti Puraskar. She is a notable woman scientist/engineer (SG-Meteorology & Wind Profiler instrumentation and range operations). Some of her most noteworthy work include commissioning the first Telecommand station at Port Blair in 2014. Ms Shanthi designed a mobile wind profiler and played a critical role in handling real time space craft anomalies thus avoiding contingency and fatalities.

Nari Shakti Puraskar (earlier known as Stree Shakti Puraskar), literally meaning “Woman Power Award”, is India’s highest civilian award for recognising the achievements and contributions of women. The awards are given away by the President of India every year on March 8, International Women’s Day at Rashtrapati Bhavan in New Delhi.

The Nari Shakti Puraskar is conferred on individual women, public and private institutions and public departments for their activism and/ or their contributions to the cause of women’s empowerment. The award, instituted in the year 1999 by the Ministry of Women and Child Development, Government of India, is given in six institutional categories and two individual categories. The award carries a cash prize of rupees one lakh and a citation.


IRNSS-1H launch from Sriharikota today. Watch it live.

SHAR Sriharikota is getting ready to launch its first private sector-built navigation satellite today at 6.59 pm. The satellite will replace one of NAVIC’s seven satellites which is malfunctioning. NAVIC is a system of seven navigational satellites powering India’s own navigation system. The 1425 kg IRNSS – 1H satellite will lift off on the back of PSLV C-39, on its 41st flight. The Indian space agency has conducted 150 missions over the last three decades, staring with Aryabhatta in 1975.

GSLV Successfully Launches India’s Latest Communication Satellite GSAT-6

ISRO had successfully deployed the India’s Geosynchronous Satellite Launch Vehicle, equipped with the indigenous Cryogenic Upper Stage (CUS), successfully launched GSAT-6, the country’s latest communication satellite, into a Geosynchronous Transfer Orbit (GTO).

The launch took place from the Second Launch Pad at the Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota, the spaceport of India. This was the fifth developmental flight of GSLV and the third to carry the indigenous CUS.  GSLV-D6 was intended to further test and qualify the CUS developed by ISRO.

The antenna is one of the most advanced features of GSAT-6 satellite and will be utilized for five spot beams over the Indian mainland, which exploit the frequency reuse scheme to increase frequency spectrum utilisation efficiency.

The satellite provides communication through five spot beams in S-band and a national beam in C-band for strategic users. The satellite’s life expectancy is nine years.

ISRO also said, the third orbit raising operation of GSAT-6 was successfully completed by firing the satellite’s onboard motors for nine minutes.

Soon after its injection into GTO, the two solar arrays of GSAT-6 were automatically deployed and the Master Control Facility (MCF) at Hassan in Karnataka took control of GSAT-6.

In the coming days, GSAT-6’s orbit will be raised from its present GTO to the final circular Geostationary Orbit (GSO) by firing the satellite’s Liquid Apogee Motor (LAM) in stages. The satellite will be commissioned into service after the completion of orbit raising operations, deployment of its 6 m wide sieve shaped unfurlable antenna, the satellite’s positioning  in its designated orbital slot of 83 degree East longitude in the GSO and in-orbit testing of its communication payloads. Flight of GSLV underscores the success of ISRO in mastering the highly complex cryogenic rocket propulsion technology.

GSLV Mark III experimental launch successful

The Indian Space Research Organisation (ISRO) has successfully launched its first test flight of its newest rocket GSLV Mark-III from Sriharikota today morning. After lift-off at 9:30AM from the second launch pad of Satish Dhawan Space Centre, the module separated from the rocket at an altitude of 126km and re-entered Earth’s atmosphere.

This rocket refers by the names GSLV Mark-III and LVM3, is a completely new vehicle marking the third generation for India’s orbital launch systems. It is capable of injecting heavier satellites like GSAT 19e. The LVM3 flight  has two active solid and liquid propulsion stages, S200 and L110 respectively in addition to its cryogenic engine C25 X, carried Crew Module Atmospheric re-entry Experiment (CARE) as its payload .

A delighted ISRO chairman Radhakrishnan said  “This was a very significant day in the history of Indian space programme for the development of the advanced launch vehicle that could carry a 4-tonne class of communication satellite into orbit.”

India started the development process a decade ago and now it has completed its first experimental flight of GSLV Mark-III vehicle. The performance of two solid stages S200 as well as liquid core stages L100 was as expected. Another experiment module in this mission, is the unmanned crew model to test and understand the re-entry characteristics, that also has worked extremely well. The crew module has splashed down as expected in Bay of Bengal

Prime Minister Mr.Narendra Modi, stated that successful launch of GSLV Mark-III is yet another triumph of brilliance and hardwork of the scientists. He congratulated all the scientists for the successful mission.

ISRO to test-fly GSLV-Mark III on December 18 2014

The GSLV-III or Geosynchronous Satellite Launch Vehicle Mark III, is a launch vehicle which is being developed by ISRO.  This will be an unmanned crew module, it will unleash India’s dream of sending its astronauts in to space come true.


ISRO scientists have been gearing up for the test launch of GSLV-MK III, on December 18th , the heaviest among Geosynchronous Launch Vehicle versions. ISRO director M.Y.S Prasad had said the launch is intended to test the atmospheric characteristics and stability of the updated rocket on its way up.

It would also carry the CARE (Crew-module Atmospheric Re-entry Experiment) Module and also study the crew module on its re-entry in to the atmosphere.

CARE will be separated from the GSLV Mk III rocket at an altitude of 126 km and a speed of 5300 m/s. It will enter a coast phase during which it will perform three axis control in order to ensure zero degree angle of attack at reentry.

The ballistic reentry will start from an altitude of about 80 km. From this altitude, the propulsion is shut down. The heat shield will experience temperatures around 1,000 degrees C and the capsule will experience decelerations of up to 13 g.

The crew module carries three stages of parachutes, all of which come in pairs. First, both 2.5-metre diameter pilot parachutes come out, followed by the 6.5-metre drogue parachutes, which cut the capsule’s velocity down to 50 m/s. Then both main parachutes are deployed at a height of about 5 km. These parachutes, each 31 metres in diameter, are the largest ever made in India.

CARE will splash down into the Bay of Bengal about 600 km from Port Blair in the Andaman Islands Immediately afterwards the main parachutes will be detached. CARE will be recovered by the India Coast Guards tracking its beacon signal. The entire duration of the experiment from launch to splash down is close to 1,140 seconds.

Mars Orbiter Mission (MOM) is ISRO’s first interplanetary mission to planet Mars with the 1350 kg spacecraft designed to orbit Mars in an elliptical orbit of 372 km by 80,000 km. The primary driving technological objective of the Rs450 crore mission is to design and realize a spacecraft with a capability to reach Mars (Martian transfer Trajectory), then to orbit around Mars (Mars Orbit Insertion) which will take about nine months time. Yet another technological challenge is to realize related deep space mission planning and communication management at a distance of nearly 400 million km.
