Sriharikota, Apr 12: The Indian Space Agency was all set to create a record of sorts as it was gearing up to launch nine more missions in the next eight months this year, including the heavy rocket GSLV Mk-III and the Chandrayaan-II mission, ISRO Chairman K Sivan said on Thursday.
If it fructifies, this would be for the first time in the annals of the Indian Space agency that its launch capabilities touched double digit, ever since it embarked on testing of sounding rocket systems.
Addressing the scientists after the successful launch of the IRNSS-1I navigation satellite by the workhorse launch vehicle PSLV-C41 from the First Launch Pad, the second mission in a gap of two weeks, he said the space agency was gearing up for a lot more launches in the next eight months this year.
'We will be launching the GSAT-29 satellite using the GSLV Mk-III rocket (carrying the indigenous cryogenic engine) and also GSAT-11, besides PSLV launches that included the Chandrayaan-II mission towards the end of the year', he added.
GSAT-29 is configured around ISRO’s enhanced I-3K Bus and will be the payload for second developmental flight of GSLV-MkIII-D2. 
It would carry Ka x Ku multi-beam and optical communication payloads for the first time. 
The mission targets for Village Resource Centres (VRC) in rural areas to bridge the digital divide.
The satellite would serve the under served and unserved populace of the country. 
About today's mission, he said he was extremely happy to announce that the PSLV-C41 precisely injected the eighth navigation satellite in the Navic constellation into the desired orbit.
He said ISRO has broken its own history of launching its second mission in a short gap of 14 days after the GSLV-Mk II mission on March 29 when GSLV-F08 successfully launched GSAT-6A Satellite into Geosynchronous Transfer Orbit, though the satellite lost its contact with the ISRO Control Centres after two orbit raising maneuveres.
Congratulating the entire ISRO community for this wonderful achievement, Dr Sivan said the PSLV-C41 was the 43rd PSLV mission. He said many new modifications has been added to this launch vehicle. UNI

Chennai, Apr 11: The 32-hour countdown for the launch of 1,425 kg navigation satellite IRNSS-1I by the indigenous rocket PSLV-C41 commenced at 2004 hrs in the spaceport of Sriharikota on Tuesday night and has been progressing smoothly.
ISRO sources on Wednesday said, in its 43rd flight, the 44.4 m tall PSLV-C41, with a lift off mass of 321 tonnes, would soar into the skies from the First Launch Pad at 0404 hrs early tomorrow morning.
During the countdown propellant filling operations would be carried out in the four stage vehicle.
About 19 minutes after lift off, the 1,425 kg satellite, would be injected into the sub-Geosynchronous Transfer Orbit (Sub-GTO) at a perigee of 284 km and an apogee of 20,650 km, with an inclination of 19.2 deg to the equator.
After carrying out Orbit raising manouevres using the onboard propulsion systems, the satellite would be placed in the Geosynchronous Orbit at a height of 36,000 km with an inclination of 29 deg.
ISRO would be using the 'XL' version of PSLV for the mission. 
This would be be 20th flight of PSLV-XL version and the 32nd PSLV mission from the First Launch Pad.
The Satellite, with a life span of ten years, would transmit signals for the determination of position, navigation and time.
It would be the ninth satellite in the Indian Regional Navigation Satellite System (IRNSS) segment.
It would also serve as a replacement for IRNSS-1A after its failure of its rubidium atomic clocks, which would provide accurate positional data.
Its predecessors, IRNSS-1A, 1B, 1C, 1D, 1E, 1F and 1G were launched by PSLV-C22, PSLV-C24, PSLV-C26, PSLV-C27, PSLV-C31, PSLV-C32 and PSLV-C33 in July 2013, April 2014, October 2014, March 2015, January 2016, March 2016 and April 2016 respectively. 
The configuration of IRNSS-1I is similar to IRNSS-1A, 1B, 1C, 1D, 1E, 1F and 1G.
Like its other IRNSS predecessors, IRNSS-1I also carries two types of payloads--navigation payload and ranging payload. 
The navigation payload of IRNSS-1I transmits signals for the determination of position, velocity and time. 
This payload was operating in L5-band and S-band. Rubidium atomic clocks are part of the navigation payload of the satellite. The ranging payload of IRNSS-1I consists of a C-band transponder, which facilitates accurate determination of the range of the satellite. 
It also carries Corner Cube Retro Reflectors for Laser Ranging.
It may be recalled the previous PSLV-C39/IRNSS-1H mission failed as the satellite did not get separated from the heat shield. UNI

Sriharikota, Jan 12: Terming the successful launch of PSLV-C40 carrying Cartosat-2 and 30 other smaller satellites as a 'big feat', ISRO Chairman A S Kiran Kumar on Friday expressed happiness over technocrats rectifying the efforts in the unsuccessful previous launch of C39 in quick time.
In his comments after the successful launch, Mr Kumar who, will be demitting office shortly said, ISRO had started 2018 in a big way. 'The last launch of PSLV C39 due to heat shield problems we had faced, the committees went through rigorously and found corrective measures that were required to make the system more
robust. Today what has happened indicates that problem is properly understood and rectified and we are extremely happy to present to the country a new year gift with Cartosat-2 series and other satellites,' he said.
The ISRO Chairman said Cartosat-2 and other satellites have been deployed successfully at the designated place. The performance of Cartosat-2 is satisfactory.
He said this year, ISRO had a large number of activities planned and the next -- the GSLV Mk-II, scheduled for launch next month, was being assembled.
Satish Dhawan Space Centre Director P Kunhikrishnan said today's success had proved that ISRO's team work had paid dividend. It is truely precious because of multiple reasons as this mission proved the correctiveness of all the measures taken in a much more efficient and effective way making the vehicle more robust and reliable. he said.
'This is the mission which turned out to be an excellent tribute to Mr Kumar, who has been the driving force with us all along. At the same time this is a mission, a welcome launch for our new Chairman designate Dr K Sivan,' Mr Kunhikrishnan said. UNI

Bengaluru, Jan 9: Indian Space Research Organisation (ISRO) will be launching PSLV-C40 with 31 satellites including earth observation spacecraft Cartosat-2 from the Satish Dhawan Spaceport in Sriharikota on January 12. 
Besides Cartosat-2, the workhorse launcher would also carry 28 foreign satellites from the US and Finland. It would also launch two other Indian satellites--- one nano spacecraft weighing just five kg and the other a micro satellite weighing about 100 kg, built by the space agency. 
With the launch of these three satellites, ISRO will be earning a distinction of launching 100 satellites in its journey of making India among the top space faring states, a top ISRO official said on Tuesday. 
The mission, whose main payload would be Cartosat-2 series earth observation satellite, will be the first PSLV mission in 2018 after the unsuccessful launch of navigation satellite IRNSS-1H in August last year. 
Speaking to reporters on the sidelines of an Exhibition on AstroSat organised by ISRO at Jawaharlal Planetorium, ISRO Satellite Centre Director M Annadurai said the mission will be a combination of 25
nano satellites, three micro-satellites and one Cartosat satellite. 
He said the other big launch coming up this year -- will be lunar mission Chandrayaan-2, on board GSLV-Mk II. Testing and integration of this orbiter and the lander-rover was in the final stages and it would fly to reach lunar orbit in the first half of this year. 
Chandrayaan-2, India's second mission to the Moon, would be an advanced version of the Chandrayaan-1 launched nine years ago. This spacecraft is a composite model consisting of orbiter, lander and rover. 
Dr Annadurai reiterated ISRO's intention of increasing the industry participation in space missions. While ISRO wants to build its capability it also involve the industry and use the excess capacity for commercial use. UNI
