and still- no images of lander crash site by "most powerful camera ever in orbit" onboard CH-2

no failure analysis report made public

such is the "transparency" of ISRO...
That actually is a little fishy.

Also, without of course revealing any classified information- there still hasn't been a nice, detailed description or assessment of all the technology aboard the Vikram lander, that did work in its ill fated mission. We know that the 800N thrusters worked well, though one of the five appeared to have malfunctioned in the descent phase. What about mechanical systems, electronics, thermal management... Did Vikram take any pics of the moon as it descended? ISRO could be a little more public about these things!

ISRO: Chandrayaan-2 detects chromium, manganese through remote sensing

India’s Chandrayaan-2 spacecraft, which has completed more than 9,000 orbits around the Moon, has detected minor elements of chromium and managanese through remote sensing, officials of the Indian Space Research Organisation (ISRO) said on Monday.

We once built a boiler and heat exchangers set in Gujarat and it took us bloody 8 months to reach Odisha. Throughout the entire route, we jammed routes, we had to remove electrical cables and poles in many areas.

At a place when a flyover bridge was not high enough for the heat exchangers loaded on our truck, we had to take permission of authorities to dig up road to cross that.
Sir if you don't my asking, who are WE here?

Ha…I predicted this. This government is not going to tolerate ISRO’s mediocre performance. They know that ISRO has fallen behind others considerably. With SpaceX well positioned to corner small payload the launch market and the massive Antrix debacle ($1 billion lawsuit by Devas), the writing is on the wall for ISRO. Neither have they been able to foster a good open source community like their western counterparts to keep citizens engaged, nor have they been able to develop talent to engineer sophisticated projects. ISRO has achieved what they could with the current talent and heavy support from the Russians. For ISRO to get to the more sophisticated technologies, the entire organization and leadership must change. ISRO needs to study how NASA, ESA and JAXA are able to work effectively with the private sector to create sophisticated space technology. ISRO also has to become a lot more transparent - especially they way they publish data for broader scientific community to make use of it. Finally, ISRO must execute programs and applications in a timely manner. NAVIC is still not finding the adoption rate it should be. The Google earth like service has been a total flop. And space education and talks by ISRO professionals at schools and universities has been pathetic - they have not lit the flame of scientific fervor in our country.
It is good that the government has finally realized that ISRO has badly let down the country. And that a complete overhaul of the organization is needed.

This is a quote by a long time ISRO person with deep knowledge of everything inside ISRO:
Jayakumar’s profile: https://www.quora.com/profile/Jayak...533&share=d9933b0c&srid=IU6B&target_type=user

Jayakumar Chandrasekharan says “ Even though I am from ISRO (retired), I have to admit your point that spaceX is far advanced than ISRO. Let me give a short history of ISRO.

As you know ISRO was an autonomous body under Department Atomic Energy. It was established by Bhabha and Sarabhai in Thumba. The main purpose at that time was to study the magnetic equator passing over Thumba. TERLS was established for launching sounding rockets, and was dedicated to United Nations later.

Later due to the initiative of Vikram Sarabhai, SSTC (Space science & technology centre), RFF (Rocket Fabrication Facility) RPP (Rocket Propellant Plant) were established to broaden the field into sounding rockets and also launch vehicles.

The project SLV-3 was approved first with a small budget and you know Kalam was the director for the project. ASLV, PSLV, GSLV, GSLV MKIII , RLV followed. Thus ISRO’s growth was gradual, and over 40 years, unlike SpaceX which started with a Big Bang.

India is always behind west by about 50 years in technology and manufacturing. We are behind Japan and China also. We are not self sufficient either in manufacturing technology or materials in Higher technology area. Even Cars manufactured in India have some import content.

In Rocket technology also such constraints are there. The developed nations simply deny us the technology or material. Therefore We have to innovate and find methods and materials to overcome these abrupt refusals. Remember the accident in which a malfunction of a simple O ring blasted the rocket along with Astronauts.

These type of constraints are not applicable to SpaceX. They have advanced technology, advanced materials, sufficient qualified and experienced personnel and moreover limited controls being a private company.

We are yet to master cryo technology fully, even though we have made cryo engines for upper stages and satellites. “

And you can see the upvotes by ISRO scientists and engineers to the above quote. ISRO simply does not have advanced talent. They are still unable to master cryogenic technology for heavy launches. And that is a fact.

Also his reply to further ISRO recruitment:

“ Yes. Government has advised ISRO to stop recruitments for scientific and technical posts.”

This observation alone says that the government has lost confidence in ISRO. It was bound to happen as ISRO is yet another PSU unable to compete with current talent. Over and out.

This is a good explanation by a propulsion engineer (Vivek Murugesan) at Bellatrix Aerospace on SpaceX’s reusable tech and why ISRO would struggle to build anything like that, as PSLV and GSLV are not engineered that way to recover launch boosters or stages. More here:

Yet another acknowledgment of ISRO's reduced capabilities. The government will now allow FDI in space sector.


Here is a specific quote from the above article, where the government is acknowledging the very issues we have been pointing out; and making course corrections. Basically to target 10% of global launch share, GoI is saying ISRO cannot do it. And I agree. ISRO's reduced capability cannot get us there.

We will have to strengthen everything from manufacturing, infrastructure to launching in order to capture a big chunk of the market. Launches have seriously gone down during the pandemic; ISRO was significantly affected. However, it is a good sign.
- Dr Rajeswari Rajagopalan, director of the centre for security, strategy and technology at the Observer Research Foundation.

Mitigating( not exculpatory) factors for ISRO- far less funding than the other major space faring countries the US, Russia, France, China, Japan; historically, much less developed industrial and manufacturing base than at least 4 of those countries; space programme doesn't possess the huge importance for prestige and geo-politics that it does for US, Russia, China, France; sanctions placed on India causing huge delays; Covid badly affecting India.
