ISRO Selects Homegrown Company To Make Its Next Navigational Satellite

 

[Flame Thrower]

Although development of Heavy lift launchers are important, we also need Agni V based launch system & 500 kg payload variant of PSLV to remain competent in the launch market.

IMHO We have a Rohini 560 sounding rocket, minor tweak and that's it. We'll have something to send less payload sats to leo and can be used to future wars too. Why tweaking Agni...

Or is it that Rohini is just not good enough to send sats... I mean guidance or something since it is just a sounding rocket

Or is it that Rohini is just not good enough to send sats..

Yup, that's the problem.

BTW, launching satellites from missiles is space power projection itself. If Americans and Soviets can, why can't we?

First Israel and now south American nations, ISRO is on the roll.

As Isro’s reputation soars, foreign nations line up at door to build, launch satellites

Mexico and Bolivia are expected to seek help from India to build and launch satellites, officials in the two countries said, in a sign of Indian Space Research Organisation’s (Isro) widening footprint.

Mexico and Bolivia are expected to seek help from India to build and launch satellites, officials in the two countries said, in a sign of Indian Space Research Organisation’s (Isro) widening footprint.
Since 1995, Isro’s workhorse launcher PSLV has launched 77 satellites — 45 of these belonging to 19 countries — and counting. Now, the Bolivian government has reached out to New Delhi to help it design and then put its communications satellite into orbit.

Director general, Bolivian Space Agency (ABE), Jhonny Ivan Zambrana Cruz, told FE: “We are working on the specifications and configurations for the construction and eventual launching of our second satellite Tupac Katari II. Once that is complete, we have an interest to work with Isro.” “Military satellite is not our priority yet; the second satellite that is on the drawing board is for our telecommunications,” Cruz added.

With an approximate investment of around $200 million, the Bolivian space agency feels that that Isro, which has to its credit the launches of several satellites at low cost, would be able to help, said sources.
According to Rajeswari Pillai Rajagopalan, head, nuclear and space policy initiative, Observer Research Foundation: “Cheaper and credible launches and India’s overall expertise is driving these countries towards India. Also, we are a bridge power between the US and Russia & China.”

Meanwhile, besides seeking India’s shoestring-budget space technology to launch its own satellites, Mexico is also keen on space agencies of both countries to work together and help in Mexico’s water management project.
Julio Cesar Castillo Urdapilleta, director of space security, Agencia Espacial Mexicana, told FE: “We are keen on finding a way to cooperate in water management project based on space-based applications. Improving water quality will be the phase one of our space cooperation.”

Javier Roch, deputy general director of industrial development, Agencia Espacial Mexicana, said: “We are looking for advantages in launching satellites and we have India on our list of countries that we would like to work with.” In April 2017, a delegation from Isro will be visiting Mexico for discussions.

Golden Jubilee of Composite Materials Activities at ISRO

Composite materials are engineering materials formed by the combination of two or more materials on a macroscopic scale, which in synergy exhibit properties better than the constituents. Composite materials are light in weight and possess better structural and thermal properties, making them suitable materials to realise structural and ablative products for launch vehicle applications. By proper selection of reinforcements and matrices, composites materials exhibit properties like transparency of radio frequency, low moisture content and low expansion under thermal environment making them ideal materials for spacecraft applications.

Among the various types of composites, considering the types of reinforcements and matrices, Polymer Matrix Composites (PMC) and Ceramic Matrix Composites (CMC) have been widely used for aerospace applications. Emergence of strong and stiff reinforcements like carbon fibre along with advances in polymer research producing high performance resins as matrix materials, have enabled the development of composite products to meet stringent requirements. The large scale use of composite products currently in space programmes are through the development and usage of structural, filament wound and thermo-structural composite products which utilise the potential of these materials. Automated and controlled design and processing of composite materials have enabled the realisation of filament wound composite products for application in pressure vessels for launch vehicles. The high temperature capabilities of carbon fiber as reinforcement and carbon matrices retaining the strength at higher temperature, have enabled the realisation of indigenous Carbon-Carbon Composite products for thermo-structural applications.

The genesis of Composites is traced to the development of payload deck, way back in 1966 for Nike Apache sounding rocket, which led to further uses of composites for both launch vehicles and spacecrafts. Competence in Composites technology in diverse range of products for ISRO’s missions has been developed in Vikram Sarabhai Space Centre (VSSC), starting from design and analysis, state-of-the-art processing, characterisation, inspection, testing and qualification with the necessary quality assurance systems.

Presently, the activity has spread its wings to meet challenging demands of Indian Space Programme. After gaining its momentum through development and successful flight products in SLV-3, the activity has now blossomed to deliver a gamut of products in all prestigious missions of ISRO. An impressive array of Composite products has performed in PSLV, GSLV, GSLV MKIII, SRE, RLV, ABPP missions as well as in Communication and Remote Sensing satellites. The activity gaining its core competence over these last five decades has also been recognised as a 'Centre of Excellence' in Composites.

VSSC celebrated the Golden Jubilee of Composites activities during December 2016. Shri A. S. Kiran Kumar, Chairman, ISRO/Secretary, DOS, inaugurated the "Golden Jubilee of five decades of Composite entity at ISRO". He highlighted the journey of Composites technology for space applications, which started under the leadership of Prof. Vikram A. Sarabhai, followed by Prof. Satish Dhawan and Dr. A. P. J. Abdul Kalam, flourished under the leadership of many stalwarts producing outstanding results. Dr. K. Sivan, Director, VSSC in his presidential address lauded the contributions of Composites Entity and mentioned that Composites team has built a legacy through development and delivery of Ablative, Molded and Thermo-structural products to meet ISRO’s mission requirements.

An exhibition of Composite products and facilities was also arranged during the event. A curtain raiser video narrating the evolution of composites activity and the impressive strides made in delivering structures for launch vehicles and spacecrafts was showcased. A document titled ‘Composites Entity–Centre of Excellence” and a “Compendium of Composite Products” were released during the event. All the former employees who were the part of the journey of composites activities were felicitated along with the Industry partners. A book with collection of reminiscences of former employees was also released as part of the event.

The event was participated by around 600 members of space community (who have been associated with Composite activities) during the inaugural function, and more than 1000 participants for the exhibition. Experts in Composites and former veterans delivered lectures during the symposium and shared the memories of initial days of development.

Ya, I'm one of those posters. And I have a friend Raghavendra to support me from Bangalore.
Originally, you can find them from VSSC space museum, National Space Science Sysposiums or Expos. I will notify you guys for next expo.

After Mars, ISRO eyes Venus and Jupiter
By: PTI | Tirupati | Published: January 4, 2017 7:34 PM

After its successful Mars Orbiter Mission (MoM), ISRO is eyeing inter-planetary missions to Jupiter and Venus. (Reuters)

After its successful Mars Orbiter Mission (MoM), ISRO is eyeing inter-planetary missions to Jupiter and Venus and is studying their feasibility.

“We are looking at other planets that we can explore. So, two of them are Jupiter and Venus. The mission analysis is on what type of satellite we are supposed to build and what type of rocket we need.

“Studies are going on and it may take few years from now to have a concrete plan,” M Nageswara Rao, Associate Director, Indian Space Research Organisation (ISRO) said at a plenary session on science technology at the Indian Science Congress here.

He added that the chance of launching a satellite to Venus comes once in 19 months, considering the distance and earth’s position.

Venus, second in order from the Sun, is nearly 162 million miles away from Earth while Jupiter, which lies between Mars and Saturn, is nearly 610 million miles away from Earth.

Rao said a follow-up mission for Mars Orbiter Mission (MoM) is also being planned.

“We want to have a follow-up Mars Mission and we want to have a mission to Venus. We want to go close, 70,000 km close (to Mars). Work for Chandrayaan 2 is also on. The project involves having a lander and a rover,” he said.

So for the first time, ISRO can have its lander land on the moon, which will give the space agency minute details of the earth’s natural satellite. Earlier envisaged as a joint collaboration with Russia, ISRO will now go solo on this project.

Chandrayaan 2 is expected to be launched next year.
