I am convinced that ISRO is in danger of not developing correctly and quickly. Many technologies like Gagan GPS have simply not been successful as expected. By now, navigation equipment in India should have been mandated to use Gagan. ISRO's Google Earth like service is nowhere. Similarly, relaunch of Chandrayaan has not happened. ISRO has lost several commercial launches to SpaceX including space station cargo flights, which could have been a lucrative business.
Further, ISRO has zero plans for technologies like space telescope, space station, rover, cargo flights, planetary habitat etc. Plus Human space flight is very very delayed. Frankly, ISRO simply does not have a list of advanced tech that they want to focus on and a plan to get there by a certain date. They are simply doing this and that without a strategy of what areas they want to develop an expertise in.
The Antrix debacle already has hurt ISRO's reputation quite a bit. The entire conduct there shows that ISRO is a very protectionist organization that is unable to open up and collaborate with others. And is weary of being surpassed by other organizations.
ISRO is still unable to launch heavy duty satellites and has to rely on Ariane space for launch of critical satellites. Almost all space faring nations have heavy launchers including private companies. ISRO is behind private companies now in heavy duty launch market. That in itself is a really bad situation to be in.
The real danger for ISRO is loss of talent - no one worth their salt works for organizations that dont deliver - and given private companies are mushrooming [look at the number of companies in Bangalore's aerospace park now] they are going to lose their talent pretty quickly. This is similar to how IAF and Air India lose its pilots. The complete absence of activities by ISRO during the last two years speaks poorly of ISRO's capabilities, especially its bench strength. Looks like ISRO is reliant on just a few scientists or engineers to make things happen. This also means ISRO has not scaled up talent development in-house. This is a really bad position for ISRO to be in and it could lead to an existential crisis for them.
I understand India is only a handful of nations that does space launches - but the question is are we just doing it to show that we are also there or are we doing it to develop some serious technology and capabilities in this space? Given how ISRO is unable to articulate a vision and scale talent to get there, I dont think ISRO will be able to deliver on a range of initiatives they have signed on. Even before the pandemic. they have been postponing human space flight for ever. That also is not a good sign for this program as well.
Since neither you belong to this sector nor have any basic knowledge of it, what you are convinced of really doesn't matter (no offence intended).

Since your post is strictly a personal opinion without any stats or real arguments or knowledge, it doesn't matter either. It's like 13 years old FB experts who were making it ISRO vs DRDO on odd days.

Establishing a system while have to compete with existing competitors takes time to establish.

GAGAN wasn't good at that, nor completely indigenous and was succeeded by NAVIC which will be succeeded by GINSS.

Mapping and clouding will improve in between the process.

Strictly because of lockdown.

ISRO isn't a business organisation which will be bidding for space station business. That's the job of India's private spaceflight companies which are in their nascent stages.

If government of India has scheduled ISRO to build a satellite constellation for country, it wouldn't go for commercial launches.
Commercial launches anyway don't even generate value equivalent 1% of ISRO's government budget and are just done to showcase its capabilities.

All of the concepts were studied in 2000s and are actually in project forms.
Astrosat-1, 2, XPoSat (to be succeeded by INSIST space telescope and Indian lunar based telescope). Indian pace station is an active and official concept being displayed at exhibitions. That would need space docking trials first. Rovers, robotics and cargos don't even need elaborations and planetary habitats are a part of long term exploration.

Obviously anyone who thinks without a dozen of space stations and planetary bases, thinking about a habitat there is sane, is simply stupid.

Hunan spaceflight progarn started with testing capsules in 2006 to today having a mid-HLV, space module being tested, abort systems, space suits, androids and space food in 2021. It actually seems faster than Chinese (1960s) and Japanese (1980s) human spaceflight programs and only behind US and Soviet ones who were literally spending a large portion of GDP on space race.

Delays and scrubs are common in manned spaceflight since deaths bring national shame. ISRO's over it is just a new entry.

ISRO's annual report and VSSC always publish list of technologies and goals with timelines on annual basis.

A space agency supposed to explore outerspace and find its applications. It's goal are clear as a research medical university.

ISRO is a PSU and not a private company and government PSUs remain vary of deals. Especially with critical techs or precious services.

GSLV MkIII actually allows that. It's production is just not enough.

No they don't. Only few and spacefaring nations even have medium launch cap and ability to reach GTO and India is latest entry (2017) among them. Except of US (Delta IV) and EU (Ariane 5), rest don't have reliable heavy launchers or yet under development. Japanese ones (H2B) as underpowered engines and problematic nozzles and not even a real HLV as safe capacity nears medium launchers, Russian (Proton-M) and Chinese (CZ-5) are unreliable. With SCE-200 engine, Indian HLV will be there in 5-7 years. Then, we will see reliability factor.

The space agencies with launch systems have relations and support from a major government agency.

Just LOL. ISRO or any other PSU's factory would never be short of engineers in a country with world's largest pool of them. Commercial launches from ISRO anyway are going decline since new space policy restricts ISRO to research and private players for launch.

It rather reflects your lack of knowledge about any basic thing. Scientists don't research on every launch of rocket they have developed and certified.

ISRO's rockets and satellite parts are largely dependent upon small subcontracting factories and companies across India. Since factories are closed, ISRO isn't getting stuff. Case closed.
Ya'll Nibbiars ISRO is Public Organization not a PSU's get your self thought about ISRO and stop writing rubbish. If want to do something join or start your own Space Start up's.

But seriously the way a moderator @Indx TechStyle is acting here is despicable!
Total fanboyism and poor excuse to prove each of his point!
he need to acknowledge the issues with ISRO. He is like, no ISRO started late that's why, ISRO had that thing that's why, that's why and that's why! And we are best! ISRO is already working on it!
He never claimed that he was the best? And his arguments look pretty solid from a common guy's POV. @Indx TechStyle is a guy who is experienced in his field. I am not saying that we should take everything an expert in a field says as truth, but in this case, I believe he is right.
Ya'll Nibbiars I find both of their arguments silly. Nothing but a useless fight. And they Don't that that accourding to the ISRO's Mission and objectives they have accomplished everything. Private venture and commercial worke is not part of Isro was part of the Antrakish until they were liquidated and the NSIL was formed they have ambitious target of STSO Launcher and like they can't just talk of Space X they are fully funded and supported by the state or else even with the Reusable Falcon 9 can't even recover the money at the current quoted price's.

Why is ISRO not transparent? That’s what raises a lot of doubts about its capabilities.


Even it’s ex-chief criticized ISRO for hiding things in the garb of national security. Why not make the FAC report of CY2 part failure public? I don’t know about others but doing such things reduces my trust in ISRO’s capabilities.

in fact sharing FAC with universities could have spurred further research and maybe even some folks would have come up with a great engineering solution. In my books, this is an ineffective decision, which again delays ISRO’s own programs. They are just not getting with the times.

Here’s a more precise article on why ISRO is unable to deliver on its promises. Do note what Jairam Ramesh has to say. He makes some valid points.


ISRO has serious gaps in its electronics capability and a risky 80% dependence on imports for its electronics. No wonder they couldn’t do any launches during the past two years as several countries shutdown production.

It seems Mangalyaan is dead 😢. After all it is designed for just 6 months mission. Hope Mangalyaan-2 will include a lander/rover in it, although it depends on Chandrayaan-3 success.

good mission Mangalyaan...but it had to end one day- no worries
Mangalyaan-2 is very hard if targeted to land on Mars...doesnt seem that ISRO will try that till Mangalyaan-3/4

Mangalyaan-2 could be a heavy orbiter only with much more punch than small Mangalyaan-1 orbiter

Landing missions are not easy! Rovers are even more difficult.
First we need to master Landing on Moon. Lets have ISRO focus on Moon landing first with Chandrayaan -3 then they should move on to Mars.

Most likely it will be Orbiter Only mission. They may decide on Lander/Rover after Chandrayaan-3. But I'm more excited for Shukrayaan-1 mission, it will likely have 11 payloads and its huge

Mangalyaan-2 will just be a heavier orbiter for Martian atmospheric mapping.
Mars does have an atmosphere unlike Moon and has much higher gravity. It will need stronger thrusters to control descent speed and heat shield to enter Martian atmosphere. On Moon, they just needed to slow down descent what isn't the case with Mars.

Guys ,I have a small thought regarding our lunar programme .Since bat eaters are planning for a Lunar Base with Russians, Why shouldn't we have a sustained Lunar Exploration Programme immediately after Chandrayaan-3 mission. Sending a man to moon is a very costly thing and we need atleast 100ton to LEO class LV , but it's very costly and it's very difficult to reuse. But I think we can use a 25 ton to LEO LV for manned mission . But before sending our men and women we should have an unmanned lunar base on the south pole with landers and rovers to explore the sites for bases and develop and demonstrate technologies like building a lunar habitat with lunar soil (for which we already have basic tech) , insitu resource utilisation to collect water and then produce LH2 and LOX and their long term storage tech and after demonstrating all the required tech then we can send another set of Landers and Rovers to build a lunar habitat and other infrastructure to collect lunar ice and produce fuels and their storage facilities.After that we can launch a single stage reusable lunar transfer vehicle which can refuel on lunar surface and can ferry astronauts from LEO to Lunar South Pole and vice versa . After this, only thing we need is, two launches of GSLV MK-3 . One carrying cargo and another carrying Crewed Spacecraft. These two will then dock with Lunar Transfer Vehicle (LTV) , and that LTV will carry our Vyomanauts to the moon base, it will refuel there ,bring them back to LEO from where Gaganyaan returns to earth, after that LTV return backs to moon base and wait until for next mission and refuel there .

Lot of it is bluster, and the only aspect that we need to worry about space is the military one and keep our capabilities good enough....hard to compete with China at this point one to one until our economy comes close to US/China not just in GDP but qualitatively....thats the reality
