ISRO General News and Updates

[Chinmoy]

That's why this step.

ISRO isn't doing it very happily actually.

With just an ability to launch 5-7 MLLVs/year which would comprise both your own missions as well as commercial launches, it's an unnecessary overload.

Market is lying there around world. Our problem is lack of production lines and hereby low launch frequency.

I neither see our infrastructure too weak nor I see you having even a little clue on what exactly is happening.

Moreover, in anyway, it doesn't affect our cost competitiveness. Not doing it will increase costs for sure.

It's only competition and privatization which reduces launch costs while making profits as well. ISRO DOESN'T TRY TO KEEP COSTS LOW AND KILL ITS PROFITS.
Nor anyone in world is reserved to launch from India. Cost will increase with global inflation. ISRO being alone Indian administration isn't going to be able to take care of any cost reduction projects.

You aren't able to get it at all.

1. DoS will become the sole space administration of the nation while ISRO chairman may not be the executive of department anymore. This administration and not ISRO itself have to issue licenses, distribute transponders and bandwidths which at first place is not supposed be to be done a research agency.
2. More launch pads will be set up across coasts and islands. Private companies will be emerging later. A launch administration will still be arriving earlier (similar to ULA. We already subcontract our launch systems to private vendors.

Expansion of SAC should take place to produce both research spacecrafts well as communication satellites in assembly lines. Communication SATs to be taken care of by other allied agencies and research probes by ISRO. Much like cold war era US & USSR.


India needs at least 100 geocentric satellites and at the same time needs to export. Mass production of satellites and launch systems is only key for it.

By "decentralization", we aren't suppressing ISRO itself. ISRO is a part of government of India just like any other agency. More offices will be built to divide work.

The REVENUE about which you are so concerned is being earned for India. For government of India. ISRO isn't supposed to be a competing agency against other government agencies for "revenue". It was never supposed to be a self funding or revenue earning agency. Government gives it money. How do I shove this up in your mind?

As long as government earns, it's same thing. (Decentralization) And if it gets liberalized (privatization), private players will multiply industry and even more money will come in form of tax.


Then, you must be aware that ISRO will still have more research budget and stupid arbitration, public wealfare and other expenditures won't be there for it.

They have built SSLV and about to sell licenses to completely produce and launch PSLV and SSLV to private vendors.

Government has been training them for years.

"Build private sector first before decentralization". Private sectors emerge only post decentralization.
You aren't relating things at the moment. Are you drunk bro?

Just two questions.............


First: Other then ISRO, who have till date even displayed a genuine capability at the rate of 10% (ISRO launch revenue)?

Second: How is it going to help private launches in India?

None, nor any in sight before 2022-23.

Second: How is it going to help private launches in India?

Decentralization has nothing to do with privatization. Both process are ongoing parallel. Yahi samjhane ki koshish kar raha hu.

Decentralization has nothing to do with privatization. Both process are ongoing parallel. Yahi samjhane ki koshish kar raha hu.

As of now, ISRO is working on both Space Research and Launching of satellites. Now if we decentralize it and ask them to just carry on the research job, then there need to have some alternative for launch. Who would be that alternative as of now? Obviously the foreign launchers.

Now if we start using their services for lets say, even 50% of our launch in a year, what do you think would be the overall budget allocation for ISRO? Its not like that GoI is going to release fund for each and every research carried out by ISRO. So from where they are going to bring in fund?

The easiest way out is to collect revenue by selling ToT to private companies and earning loyalties. But as of now, we can all see how our private industries fair in absorbing tech.


So now if we want ISRO to solely dedicate for core research, we have to first create industry to share the current burden which it is carrying all alone. Decentralization is the way forward, but .... but not untill we create agencies to share the burden.

 

[Indx TechStyle]

As of now, ISRO is working on both Space Research and Launching of satellites. Now if we decentralize it and ask them to just carry on the research job, then there need to have some alternative for launch.

As of now ISRO,

1. Is an arbitration committee for dispute between companies.
2. SAC and ISRO have full load of making both communication and research spacecrafts.
3. ISRO has full load of all orbital launches.
4. ISRO bears full load building infrastructure around.
5. Making an alternative agency for launch would include creation of a new government agency dedicated entirely to launch and expansion of SAC to use assembly lines for making satellites. ISRO will be giving them inputs for requirements of their research missions. Privatization is another thing.

Now if we start using their services for lets say, even 50% of our launch in a year, what do you think would be the overall budget allocation for ISRO?

Budget will exclude expenditures that were supposed to provided for tasks ISRO no longer performs.

Its not like that GoI is going to release fund for each and every research carried out by ISRO. So from where they are going to bring in fund?

Well, looking at the pace of budget for a decade, I don't see GoI any reluctant to release budget for any kind of research.

Since when ISRO started doing missions on commercial launch revenue. It can't even bear overhead expenditures of DoS for a day.

The easiest way out is to collect revenue by selling ToT to private companies and earning loyalties. But as of now, we can all see how our private industries fair in absorbing tech.

They are absorbing tech, paying money and building satellites and rockets to ISRO. Over 50% shares in some missions.

They have even started funding launches and will achieve even a 100% privatized license built PSLV before 2022.

It's only a matter of time when their own designs mature. We don't need to wait for their designs to give them contracts to launch PSLV, we don't even need to wait for them to expand DoS and shift charge of launches from ISRO to a new agency.

So now if we want ISRO to solely dedicate for core research, we have to first create industry to share the current burden which it is carrying all alone. Decentralization is the way forward, but .... but not untill we create agencies to share the burden.

Government isn't going abandon launches by ISRO without giving charge to a launch agency or a consortium of launch agencies with launch frequency above 10/year.

 

[Chinmoy]

As of now ISRO,

1. Is an arbitration committee for dispute between companies.
2. SAC and ISRO have full load of making both communication and research spacecrafts.

5. Making an alternative agency for launch would include creation of a new government agency dedicated entirely to launch and expansion of SAC to use assembly lines for making satellites. ISRO will be giving them inputs for requirements of their research missions. Privatization is another thing.

Point 1 & 2 means ISRO is already Decentralized.
Point 5 is nowhere in sight as of now and it should be discussed instead of DECENTRALIZING ISRO. This is what I am talking of till now.
Point 3 & 4 means that ISRO is getting funds for infrastructure buildup and launches and if you remember, ISRO did infact returned unutilized funds in past. Means it is not just running on Govt funds but with funds which it is getting on behalf of commercial launch, no matter how small it is. So once you set up a different launch arm, how are you going to tackle the 10% or 20% loss?

Budget will exclude expenditures that were supposed to provided for tasks ISRO no longer performs.

Sure budget would exclude lets say the launch expenditure. Now if GoI is allocating, say INR 100 per launch, ISRO is spending 80 or 90 INR per launch. So excluding that INR 100 means ISRO is going to loose INR 10. How to tackle that?

Well, looking at the pace of budget for a decade, I don't see GoI any reluctant to release budget for any kind of research.

What makes you feel so? Remember that its not the Govt, but the bureaucracy which makes plans in India. Government is just there to layout a vision. Looking at the expenditure on our R&D, our bureaucracy would prefer a commercially viable entity rather then a money guzzling R&D sector.

Since when ISRO started doing missions on commercial launch revenue. It can't even bear overhead expenditures of DoS for a day.

The day ANTRIX was formed, ISRO started doing missions on commercial launch revenue.

They are absorbing tech, paying money and building satellites and rockets to ISRO. Over 50% shares in some missions.

They have even started funding launches and will achieve even a 100% privatized license built PSLV before 2022.

It's only a matter of time when their own designs mature. We don't need to wait for their designs to give them contracts to launch PSLV, we don't even need to wait for them to expand DoS and shift charge of launches from ISRO to a new agency.

Government isn't going abandon launches by ISRO without giving charge to a launch agency or a consortium of launch agencies with launch frequency above 10/year.

Building sub components of a rocket is one thing and building a rocket is another.

My point is simple............ Why the f*** talk about decentralizing a institute which is working well in both commercial and developmental aspect?
ISRO is talking of technologies to bring down the launch costs. So why not follow that path instead to start with? Try to set up facility which would facilitate ISRO to achieve the same. That way you are going to take burden off ISRO. Talk about facilitating and developing supplementary organizations with ISRO instead of talking on DECENTRALIZATION.

But it seems we are into tying the cart in front of bull instead the other way around.

 

[SKC]

What happened to the GSLV launch which was supposed to happen in 12-16 Feb window.
Is it postponed? whats the new NET date.

 

[Indx TechStyle]

Point 1 & 2 means ISRO is already Decentralized.

No, ISRO as of now administers these organizations.
It's a space administration with powers close to that of DoS.

Point 5 is nowhere in sight as of now and

Refer to some previous old pages of thread. I will find for you later.

it should be discussed instead of DECENTRALIZING ISRO.

It exists and giving authority to it needs DECENTRALIZATION of ISRO. ISRO (Government of India) is one and only customer in India which happens to be a market for launch services.

ISRO did infact returned unutilized funds in past. Means it is not just running on Govt funds but with funds which it is getting on behalf of commercial launch, no matter how small it is. So once you set up a different launch arm, how are you going to tackle the 10% or 20% loss?

Read it again and tell me what you wish to say. I'm not able to get what exactly your point is.

Other agency if built too will be returning funds, will not be smaller also. Government most certainly isn't satisfied with revenue and it matters if it's small. And if an entirely new economic private sector can replace government which can become another pillar of economy in long term, I don't think any government in world would care a few hundred million dollars.

Sure budget would exclude lets say the launch expenditure.

No, it would exclude annual commercial launch expenditures. ISRO will still be paying launch fee to launch contractor.

Even just for showing if agency is government.

ISRO is spending 80 or 90 INR per launch. So excluding that INR 100 means ISRO is going to loose INR 10. How to tackle that?

That is not the big deal. It amounts to nothing a dedicated agency will generate hundreds of crores of profits.

ISRO doesn't run itself on these ₹10 crores.

What makes you feel so? Remember that its not the Govt, but the bureaucracy which makes plans in India. Government is just there to layout a vision. Looking at the expenditure on our R&D, our bureaucracy would prefer a commercially viable entity rather then a money guzzling R&D sector.

Government has been ramping up R&D budgets in all sectors in past 2-3 years. Especially in space research and asked commercial entity to transfer technology to private players.

The day ANTRIX was formed, ISRO started doing missions on commercial launch revenue.

Look what I said:

Since when ISRO started doing missions on commercial launch revenue. It can't even bear overhead expenditures of DoS for a day.

Commercial launch revenues are too insignificant to act as pocket money for ISRO and don't matter. ISRO executes missions on government's funding.

Building sub components of a rocket is one thing and building a rocket is another.

If they are building 100% of sub-components of a rocket, I don't think assembling it as a final system will be a problem for them and will be given assistance for initial few launches if they need.

My point is simple............ Why the f*** talk about decentralizing a institute which is working well in both commercial and developmental aspect?

ISRO never worked more "well" than any other Indian PSU in any aspect. It's our dumbo to criticize DRDO and embrace ISRO. ISRO just happens to be world's few active space agencies.

ISRO for decades was nothing better than Italian and Israeli space agencies and gained full launch capability only in mid-2010s. It can't bear more than 5-7 launches an year despite using smallest medium lift-launch vehicle, worst among world's 6 agencies with full launch capabilities.

It was most late in party to enter space exploration. It's overloaded yet unnecessarily to take care of commercial launches while other five have already sub-contracted their launches to private players to increase frequency decades ago.

NASA to ULA, SpaceX and Blue Origin etc., ESA to Ariane and other European companies, JAXA to Mitsubishi and CNSA & RFSA to their government launch agencies.

We take 1-1.5 months to fabricate and assemble a fckin rocket what China and US can do in 10 days or 2 weeks and Russia in 3 weeks. More people doing it will generate more launch slots.

Low launch frequency, low budget, no modular rockets, small number of satellites and what not. GOI has now changed mind to expand Indian space program. So, huge elevations in budget, and new institutions will follow. IIA may soon enter decision making bodies too.

28th February per unreliable sources.

 

[Suryavanshi]

But it would also mean that we would be facing heavy competition on the launch market which as of now is a major source of income for ISRO as well as GOI. Now that is one serious matter of concern IMO.

I have a solution for this.

Industries can have a collaboration with ISRO where they would license key technologies from them, in this way we can eliminate foreign imports and develope local capability ourselves.
We will keep space related transactions tax free or give tax break initially
Once the industries have developed technological self reliance and start genertaiing decent revenue we will start taxing them on their profit this will make up for the loss of licensed revenue.

I woudl still prefer for ISRO to continue as chief researcher, with a total market cap of 25 to 30% of space related sector.

This is happenin as we debate..
ISRO is aleady transfering tech to pvt industries..and they are builiding a capable industry system for space launches..
The tax and related breaks are already there for such startups and industries.

We finally have details on a SSLV payload.

Microsat-2A: The satellite is being realised based on Microsat-TD to demonstrate launch on demand capability with SSLV. It is expected to meet the ever-increasing user demands for cartographic applications at cadastral level, urban and rural management, coastal land use and regulation, utilities mapping, development and various other GIS applications. The satellite carries two payloads, MWIR & LWIR, with 6m resolution. The mass of the spacecraft is 142 kg and it will be placed at an altitude of 350 km. The mission life of the satellite is 10 months.

On Small Satellite launch Vehicle

SSLV-D1: Design of all vehicle systems is completed and hardware realisation is progressing in fast track mode. The activities towards static test of first stage solid motor (SS1) are progressing. Acceptance testing of second stage (SS2) flight motor case completed. Third stage (SS3) motor is under propellant processing.

Design & realisation of new Mission Management Computer (MMC) and Sequencing Execution Module (SEM) has been completed. A new miniaturized telemetry system has been developed for SSLV achieving 70 % mass reduction in the telemetry package. Characterization of vehicle configuration through wind tunnel tests and CFD are nearing completion.

Vibration test of propellant tank for Velocity Trimming Module were completed. 50N thrusters & valves were realised. Assembly and integration scheme and flight measurement plans were finalised.

On Reusable Launch Vehicle (RLV)

Reusable Launch Vehicle (RLV): The objective of RLV is to demonstrate technologies for developing a wing body vehicle similar to that of an aircraft. RLV will ascent to orbit, stay there, re-enter and land on a runway like an aeroplane. The technology has the challenges of meeting the complexities of both the launch vehicle and aircraft.

RLV Landing Experiment: It is planned for the last quarter of 2019. RLV wing body will be carried using a helicopter and released at a distance of ~4-5 km ahead of the runway with a horizontal velocity. The RLV will glide, navigate towards the runway and land autonomously with a landing gear in an air field near Chitradurga in Karnataka. Control and Guidance design and all structural designs were completed. RLV flight hardware has been realised. Structural test of RLV Engineering Model has been completed. RLV Interface System (RIS) for interfacing with helicopter and Qualification Model of landing gear were realised

On Air Breathing Propulsion Project (ABPP) and HAVA

Hypersonic Air Breathing Vehicle with Air frame integrated system (HAVA): It is a lifting body hypersonic vehicle integrated with scramjet engine, boosted by ADMIRE booster to an altitude of 44 km and glide down to 25 km altitude with a Mach number of 6. The objective is to demonstrate accelerating flight of a hypersonic vehicle with scramjet engine power from Mach 6 to Mach 7 in 250 seconds at constant dynamic pressure. The data base generated can be used for the design and development of a Two-Stage-to-Orbit (TSTO) vehicle, powered by air breathing combined cycle engine. Isrosene is considered as fuel for HAVA. System engineering and design has been completed.

Fabrication of heat sink version of Scramjet test combustor, configuration of air intake cowl opening mechanism and effervescent Isrosene injector were completed. Hot test of GH2-GO2 based dump igniter was carried out.

On Test Vehicle Project (TVP) for inflight abort test

Test Vehicle is a single stage liquid propelled launch vehicle being developed to validate the Crew Escape System (CES) performance at different critical Mach numbers, viz, transonic, Qmax, Mach 2.0 and Mach 2.5. Test Vehicle mimics the Human Rated Launch Vehicle trajectory during its atmospheric regime, carries CES as payload and places it at the predefined “M-q’ pill box. This vehicle uses the already proven L-40 earth storable propulsive system with reduced Area Ratio nozzle, new structural elements and full-fledged autonomous avionics & NGC systems. Dual plane Engine Gimbal and Fin Tip Control (4 fins) using electro-hydraulic actuators are planned.

On Gaganyaan progress

Development of Technologies for Gaganyaan: Configuration of Crew Escape System (CES) for Gaganyaan has been finalised. The configuration has five quick acting solid motors which use newly developed high burn rate propellant system. Four nos. of gridded deployable fins are provided in CES for aerodynamic stability. Preliminary design of all metallic structures in CES has been completed and fabrication drawings were released. Material procurement is progressing in fast track mode. Separation of Crew Module (CM) to CES is effected by firing explosive nuts in the linkage system. Design of grid fin deployment mechanism and CES separation system are in advanced stage. Crew Module for Gaganyaan with a height of 3 m & 3.5 m diameter is configured for accommodating a crew of 3. It has a double walled configuration, with inner pressurised shell made of Aluminium alloy having welded construction and external structure configured with CFRP honey comb panels bonded with TPS tiles. The design of structure is in advanced stage and material procurement is in progress.

The parachute systems are configured with redundancy. An MoU has been signed with Aerial Delivery Research and Development Establishment [ADRDE], DRDO, Agra for design and realisation of parachute systems.

The designs of Crew Module to Service Module separation system, Umbilical Retention and Separation System (URSS), Orbital Module to LV separation system and the separation systems required for parachute release are in advanced stage. Development tests have been commenced.

CES avionics is configured as an independent system including instrumentation system and sequencing system. Instrumentation and telemetry requirements have been finalised. For the Crew Module, configuration of Health Management System (IVHM) and Data Acquisition System (IDAQ) and its electrical interfaces were finalised.

RLV will be basically used as TSTO vehicle fitted with scramjet engine so basically isro is testing them differently . HAVA is nothing but a HSTDV. The scramjet engines that isro tested till now were dual mode ramjet engines which are different.

One more important thing if you have noticed. Isro is developing a Test vehicle for Space capsule. I think it will be similar to Boeing starliner test.

Development of Technologies for Gaganyaan: Configuration of Crew Escape System (CES) for Gaganyaan has been finalised. The configuration has five quick acting solid motors which use newly developed high burn rate propellant system. Four nos. of gridded deployable fins are provided in CES for aerodynamic stability. Preliminary design of all metallic structures in CES has been completed and fabrication drawings were released. Material procurement is progressing in fast track mode. Separation of Crew Module (CM) to CES is effected by firing explosive nuts in the linkage system. Design of grid fin deployment mechanism and CES separation system are in advanced stage. Crew Module for Gaganyaan with a height of 3 m & 3.5 m diameter is configured for accommodating a crew of 3. It has a double walled configuration, with inner pressurised shell made of Aluminium alloy having welded construction and external structure configured with CFRP honey comb panels bonded with TPS tiles. The design of structure is in advanced stage and material procurement is in progress.

The parachute systems are configured with redundancy. An MoU has been signed with Aerial Delivery Research and Development Establishment [ADRDE], DRDO, Agra for design and realisation of parachute systems.

The designs of Crew Module to Service Module separation system, Umbilical Retention and Separation System (URSS), Orbital Module to LV separation system and the separation systems required for parachute release are in advanced stage. Development tests have been commenced.

CES avionics is configured as an independent system including instrumentation system and sequencing system. Instrumentation and telemetry requirements have been finalised. For the Crew Module, configuration of Health Management System (IVHM) and Data Acquisition System (IDAQ) and its electrical interfaces were finalised.

So isro officially accepted about ADMIRE rocket :biggrin2:

As I already mentioned in my first post, in our case it has its own pros & cons. You just supported the same in your last line.

Now even if we take the revenue collection from satellite launch to be 10%, by outsourcing the same ISRO would get a deduction of 10% from its budget. Means they would have to recover it from somewhere. Increasing funding to ISRO also takes into account the 10% revenue into account.
Now after that has been cut, would government subsidize it? Right now government has increased the budget since it is the single space entity. Would they be doing the same if it gets decentralized?
What would be its impact then?

that heavily promoted "private" space company got all it's technology free from NASA and yet has trouble competing. While morgan assigns untold billions in valuation to that company they have to continually raise billions in fresh investor capital.

They initially tried to get ISRO to "cooperate" with this space thing. When that went now where this proposal has come forward to kill ISRO

They had accepted it 4 years ago. AFAIK the chairman talking about it in press is same thing.

AFAIK, ULA is very successful and even benefitted NASA.

ISRO doesn't even survive or earn pocket money on launches. Noting is going to "kill" it. How long the fragile minds of you people will take to get it?

4.
Space Act
The department is in the process of enacting a legislation to support overall growth of the space
activities in India with a higher order of participation of various agencies including public/ non-
governmental/private sector stake holders, in compliance with the obligations under international
treaties on space activities. The proposed legislation upon enactment through Parliament would
support the pursuance of space activities by various agencies in India including private sector and
start-up companies in aerospace sector, under due authorisation by the Central Government.

No, ISRO as of now administers these organizations.
It's a space administration with powers close to that of DoS.

Refer to some previous old pages of thread. I will find for you later.

It exists and giving authority to it needs DECENTRALIZATION of ISRO. ISRO (Government of India) is one and only customer in India which happens to be a market for launch services.

Read it again and tell me what you wish to say. I'm not able to get what exactly your point is.

Other agency if built too will be returning funds, will not be smaller also. Government most certainly isn't satisfied with revenue and it matters if it's small. And if an entirely new economic private sector can replace government which can become another pillar of economy in long term, I don't think any government in world would care a few hundred million dollars.

No, it would exclude annual commercial launch expenditures. ISRO will still be paying launch fee to launch contractor.

Even just for showing if agency is government.

That is not the big deal. It amounts to nothing a dedicated agency will generate hundreds of crores of profits.

ISRO doesn't run itself on these ₹10 crores.

Government has been ramping up R&D budgets in all sectors in past 2-3 years. Especially in space research and asked commercial entity to transfer technology to private players.

Look what I said:

Commercial launch revenues are too insignificant to act as pocket money for ISRO and don't matter. ISRO executes missions on government's funding.

If they are building 100% of sub-components of a rocket, I don't think assembling it as a final system will be a problem for them and will be given assistance for initial few launches if they need.

ISRO never worked more "well" than any other Indian PSU in any aspect. It's our dumbo to criticize DRDO and embrace ISRO. ISRO just happens to be world's few active space agencies.

ISRO for decades was nothing better than Italian and Israeli space agencies and gained full launch capability only in mid-2010s. It can't bear more than 5-7 launches an year despite using smallest medium lift-launch vehicle, worst among world's 6 agencies with full launch capabilities.

It was most late in party to enter space exploration. It's overloaded yet unnecessarily to take care of commercial launches while other five have already sub-contracted their launches to private players to increase frequency decades ago.

NASA to ULA, SpaceX and Blue Origin etc., ESA to Ariane and other European companies, JAXA to Mitsubishi and CNSA & RFSA to their government launch agencies.

We take 1-1.5 months to fabricate and assemble a fckin rocket what China and US can do in 10 days or 2 weeks and Russia in 3 weeks. More people doing it will generate more launch slots.

Low launch frequency, low budget, no modular rockets, small number of satellites and what not. GOI has now changed mind to expand Indian space program. So, huge elevations in budget, and new institutions will follow. IIA may soon enter decision making bodies too.

First of all, GOI is not going to fund a pure R&D based organization. Saying that we would be 5 trillion USD economy by 2025 and so we could fund it is nothing more then wet dream as of now. Even US of A didn't do it for NASA. ISRO would have to be commercially viable in one way or other to survive the bureaucracy of India.

Now for ISRO there are two ways to remain commercially viable in space market. First by building satellites and second through commercial launch. Now satellite building is something where we have a upcoming market and in coming days there would be many entities who would be building satellites. I would not be surprised if tomorrow some private company would come up with a national project of satellite manufacturing. Where would ISRO stand then?

On second point, having a viable robust launching ecosystem like ISRO would be a distant dream for any other private company. But setting up a dedicated government launch facility is feasible. But in that scenario also, would Government provide adequate funding to ISRO just for R&D?

Setting up of different agencies for specific functionality brings its associated problem in case of India. Tomorrow any Tom Dick or Harry would question the budget allocation to ISRO just for R&D purpose if it looses its commercial sheen. Do you think the government would carry on the budget allocation? We have record of seeing budget cut for RA&W. Record of seeing questions being raised on MI. ISRO is just a small pawn in our dirty politics.
