have any objective of the Indian manned spaceflight program been revealed?
does it have any particular objective other than national pride?
This I think is the weakest point in the plan - what next after flying people for several orbits? The Indians aren't in the ISS project right now and doesn't seems to have any target in mind right now. Keep in mind that the Chinese always wanted to get to operating a space station back when their human spaceflight project was approved in the early 1990s!

That's your opinion, and once again it's not universally shared. I think India has its own "flexible path" agenda on human spaceflight. There are plans to do orbital rendezvous with unmanned satellites, which can be used as the basis for farther missions.
Space is seen as valuable for its resource potential, and some kind of human presence will be required to see it through.

First of all Human Spaceflight has almost zero practical uses and that shouldn't change for at least a few decades.
Now that we have this in mind, all the so called objectives like building a space station doesn't make complete sense. No country would pour the kind of resources needed for HSF just for "carrying microgravity experiments". The objective here is to have the technology required for HSF so that India doesn't stay behind when this technology has some practical use in the future. This the main objective for any country pursuing such projects.
Building Space stations etc are just temporary objectives with national pride and technological capability being the main ones. If the objective being discussed here is indeed the temporary objective then India has said that they have plans for a manned lunar landing and what not.

Perhaps I wrong, but ISRO does not seem to have actually approved this program. For what I can tell, there has been approval of study and early design, but not full approval for a flight program.

You mean, other than the vaccines that have been developed on the ISS, right? .. not to mention all the pharmaceutical work done on earlier Shuttle missions.
There'd be a lot more of it going on if it wasn't so expensive, and controlled by NASA.

I don't know of a single existing vaccine developed on the ISS. I would welcome a publication reference, if you have one.

Point taken. I said "First of all Human Spaceflight has
almost zero practical uses and that shouldn't change for at least a few decades." But I did mention microgravity experiments.
I am not claiming HSF has zero uses in the real world. The question here is whether HSF currently has enough practical uses so that national pride and technology showcase stop being the major drivers for it.

Leaving aside national pride (and that is clearly a part of most if not all national human spaceflight plans), one objective of such high profile missions is to generate interest and excitement in young people and attract them to work for the space organization. ISRO pays Government salaries to its employees, and while the perks are good, the overall compensation is nowhere close to what the individuals can earn in the private sector within India, leave along working outside India. What has kept its turnover rates manageable is partly the excitement and pride in one's job that working for ISRO can evoke. That is enhanced by high profile missions like the planetary exploration missions and human spaceflight. Beyond ISRO, there are spillover benefits for science as a whole. Finally, national pride can have its plus sides too.
The costs and benefits of such a strategy can of course be debated. But it is an important part of the considerations for such missions on the part of the decision makers.

Thanks for posting the first picture that at least I have come across of the engineering prototype of the space suit. What is the source for the photograph - is this in the public domain and can this be posted elsewhere (an if yes, who should be given the credit for the photo). Also, which agency is involved in making and testing the space suit?

"The structure is in Thiruvananthapuram and our team has begun the process of instrumentation, likely to be completed in four to six weeks."
"The instruments that need to go in are those related to crew support, navigation, guidance and control systems and so on," the official said, adding that the agency will not be testing life support system crucial for any manned mission this time.
agency is in a parallel manner developing a specialized parachute, which will be instrumental in bringing the crew module back safely
Upon successful testing of the crew module, the space agency will commence testing of the life support system, environmental control and crew escape system.
The module is reusable as per the source below

Source was ISRO but not public (required some weekend research). you can post it anywhr you ant and give credit to ISRO.

Successful testing of Parachute Recovery System for Human Space ProgrammeAerial Delivery Research and Development Establishment (ADRDE), Agra, successfully conducted testing of Parachute Recovery System for Human Space Programme of Indian Space Research Organisation (ISRO) on 18 January 2014 by para dropping
simulated load weighing 5 ton against actual
system requirement of 3.6 ton at Agra Drop Zone using IL-76 Aircraft.
The trial preceded a series of eight successful sub-systems level air-drop tests from AN-32 aircraft.
The system has been designed for safe landing of a crew module of 3.6 ton weight class on sea surface. The recovery system consists of a pilot parachute, a drogue parachute and a main parachute.In this simulated test, with integrated parachute system, the simulated load was extracted from IL-76
aircraft by extractor parachute. Subsequently a drogue parachute was deployed which in turn deployed the
main parachute. This test successfully verified the sequence of parachute deployment, configuration of the
parachute, deployment bag and other sub-systems using onboard instrumentation. ADRDE has also successfully demonstrated this technology by recovering a 500 kg class actual module for ISRO in 2007. The successful test was backed by various technologies, viz., high performance textiles, aerodynamic design, configuration optimisation, fabrication, integration, testing, validation, etc.

A capsule mass of only 3.6 t is pretty good. I though it was going to be much heavier.
