Chandrayan-2 Expected to be Launched in Early 2019

ISRO would have two missions Chandrayan-2 by GSLV Mark 3 and the PSLV P45 launching RA-SAT 2B next year.

India’s second moon mission Chandrayaan-2 will now be launched in the January-March window in 2019 instead of later this year as the design was changed to enable it land on the lunar surface, a top ISRO official said here today.

“We have planned to launch Chandrayaan mission in January 3. We are fixing with that (date) and targeting that. But that is an open window. We can go up to March also. As we are coming closer (the date), we may miss the target,” he said.

The reason for postponing the mission was that there were certain important changes made in the design so that it could easily land on the lunar surface, he said.

He was speaking on the sidelines of a function, where bust of Dr Vikram Sarabhai, the architect of the Indian space mission, was unveiled.

Asked why the weight of Chandrayaan-2 was increased by 600 kg, he said ISRO noticed during experiments that after the moon lander was ejected, the satellite would shake. So they decided that the design modification was required for landing and mass has to be increased.

“We also realised that the orbiter required more phases, which required more fuel,” he told reporters.

On the space agency’s future missions, Sivan said ISRO also plans to launch 50 satellites in the next three years.

the space agency would launch 22 satellites in 2019, the maximum in any year in the history of ISRO, he said.

“Next year from February to December we plan to have 22 missions with almost two missions per month, which is a very important activity. This tight schedule of programmes we are doing for the first time.

We have set a target.We may not be able achieve but we are targeting it. So many missions in a year is a huge target for the first time in the history of ISRO,” Sivan said.

The remaining months of 2018 would also be very hectic for ISRO as it plans to launch at least two missions every month, he said.

“Our next mission is PSLV C42, which will launch NOVASAT and S1-4. These two satellites are commercial satellites from the U.K.It is a commercial mission and is planned in September. Subsequently we have two missions each month,” the ISRO chief said.

In October this year ISRO would launch GSAT29 for the Digital India programme and hyper spectrum imaging satellites along with 30 commercial satellites, Sivan said.

The following month GSAT-7A will be launched, while in December there would be two missions,GSLV-F11 launching AMISAT and GSAT-31, a replacement for INSAT 4CR, whose life will get over by January, he said.

ISRO would have two missions Chandrayan-2 by GSLV Mark 3 and the PSLV P45 launching RA-SAT 2B next year.

The focus area of these launches was to enhance the communication so that rural India gets high bandwidth data connectivity, somewhere between 80 GBPS to 100 GBPS, he said.

Asked about GSAT 6A, with which communication had been lost after its launch in March 31 this year, he said ISRO has not given up hope and was still trying to establish radar contact with the satellite.

“We have not given up hope. We will wait till a year,” he said when asked how much time ISRO would take to announce that the GSAT 6A was a failed mission. (IANS)

CMFRI, ISRO Join Hands to Protect Coastal Wetlands

“Wetlands are highly prospective for some selective aquaculture ventures which will help the local people earn economical gains” he added

In an effort to build resilience against the impact of climate change on wetlands, the Central Marine Fisheries Research Institute (CMFRI) and the Indian Space Research Organisation (ISRO) have teamed up to map, validate and protect smaller wetlands in the coastal region and restore them through coastal livelihood programmes.

This is the first time that a fisheries institute is collaborating with the ISRO to develop a comprehensive climate resilient framework for fisheries and wetlands.

A Memorandum of Understanding (MoU) was signed between the CMFRI and the Space Applications Centre (SAC) of the ISRO to develop a mobile app and a centralised web portal with complete database of wetlands in the country which were smaller than 2.25 hectares.

Such smaller wetlands cover an area of more than 5 lakh hectares across the country, with Kerala alone having as many as 2,592 such wetlands.

According to the MoU, the two institutes will identify and demarcate the wetlands and restore the degraded ones through suitable livelihood options such as coastal aquaculture.

The mobile app will be used for real-time monitoring of the wetlands and giving advisories to the stakeholders and the coastal people.

The collaborative move is part of a national framework for fisheries and wetlands recently developed by the National Innovations in Climate Resilient Agriculture (NICRA), a project of the CMFRI.

The NICRA project aims to find ways and means to mitigate the impact of climate change on marine fisheries and coastal region. According to the MoU, the National Wetland Atlas, already developed by the SAC, will be updated with real-time data of physical, chemical and biological parameters of the wetlands to be provided by the CMFRI.

P.U. Zacharia, who is attached to the NICRA project, said the real-time data of the demarcated coastal wetlands would greatly help in developing a conservation plan for the degraded wetlands in the region, besides utilising these resources for livelihood prospects in the area such as shrimp and crab farming.

“Smaller wetlands across the country are in a highly neglected state owing to multiple reasons. Climate variability induced rainfall drastically changes the physio-chemical characteristics of such wetlands, which was evidently seen during the devastating floods in Kerala last year.

“The collaborative initiative will help develop a comprehensive wetland information system which could facilitate the village-level wetland advisories to the local people by scientific communities,” Zacharia said.

“Wetlands are highly prospective for some selective aquaculture ventures which will help the local people earn economical gains” he added. (IANS)
