From ISRO annual report 2015-16:
Crew Escape System (CES): The first major milestone in CES qualification is the Pad Abort Test (PAT) flight, to demonstrate the functioning of CES during any emergency condition occurring at launch pad. Design of structural elements, namely, Nose Cone, Pitch Motor Compartment, Inter-stage, Crew Module Fairing and Igniters for motors, have been completed. Fabrication activities are in progress for realisation of sub-systems.
Crew Module (CM) Systems: Crew Module for PAT flight has the same configuration as flown in CARE mission. Realisation of CM with metallic inner structure, CFRP panels and honeycomb avionics deck is in progress at work centres. Additional qualification tests have been planned on Parachute system to enhance its robustness. A high rate Inertial Navigation System is included in PAT flight for measuring CM attitude after separation from CES.
Environmental Control and Life Support Systems (ECLSS): Significant progress has been made in the functional modules of ECLSS like Carbon dioxide and Odour Removal System [CORS], Temperature and Humidity Control System [THCS] and Cabin Pressure Control System [CPCS]. As part of CORS development, comprehensive tests using Lithium Hydroxide (LiOH) pellets were carried out to evaluate pressure drop across canisters. Testing of THCS as an integrated unit comprising of the various types of heat exchangers is in progress. A thermo-vacuum chamber for testing space radiator and Gas bottle to store high pressure Oxygen were realised and successfully qualified.

http://pib.nic.in/newsite/efeatures.aspx?relid=148271ISRO has taken up the development of critical technologies as part of pre-project activities for the Manned Space Programme. Major activities identified under Pre-Project are Crew Module (CM) systems, Environmental Control & Life Support System (ECLSS), Flight Suit and Crew Escape System (CES). The Crew module was flight tested in the experimental mission of GSLV MkIII on December 18, 2014 and the re-entry characteristics and the recovery of the Crew Module were successfully demonstrated. The flight suit development has been completed. Development of the ECLSS and the Crew Escape Systems are progressing well and is targeted to be completed in 2016-17.
As of now, Manned Space Programme is not an approved programme. Currently, ISRO is developing critical technologies relevant for human spaceflight for building future capacity. No cooperation or assistance has been sought from any other country during the last two years in this regard.
This information was provided by the Union Minister of State (Independent Charge) Development of North-Eastern Region (DoNER), MoS PMO, Personnel, Public Grievances & Pensions, Atomic Energy and Space, Dr Jitendra Singh in written reply to a question in Lok Sabha today.

http://www.newindianexpress.com/cities/chennai/Coming-up-Pad-Abort-Test-before-manned-mission/2016/09/27/article3630658.ece Inching closer to a manned mission, the Indian Space Research Organisation (ISRO) will soon be conducting a ‘Pad Abort Test’, which is a launch escape system to find out how well the system would get the crew of a spacecraft to safety in an emergency on the launch pad. The test is likely by this year end.
As part of this process, the pad abort test will be done. “The technology is in its final stages of development. Depending on our work schedule, we will plan the technology demonstrator. What we are planning to do is place a crew module in one of stages of a rocket and retrofire it to bring it back safely. The landing will be either on land or sea,” Kiran Kumar said.
The ISRO chairman said another critical technology “environmental controlled chamber” was in the development stage. This was primarily to control the toxic gases for astronauts to survive.

I was sceptical whether a escape capsule would work practically but it seems a soyuz crew had a successful escape in 1983 using a escape capsule system . Its a very interesting read.

http://www.newindianexpress.com/cities/chennai/2016/dec/03/def-lab-works-on-food-for-spaceflight-crew-1545121.html CHENNAI: The Mysuru-based Defence Food Research Laboratory (DFRL) is planning to prepare food for India’s Human Spaceflight Programme that will carry a two-member crew to a low earth orbit, according to Rakesh Kumar Sharma, director, DFRL.
Indian Air Force’s Institute of Aerospace Medicine (IAM) is researching the physiological and psychological needs for Indian Space Research Organisation’s (ISRO) human spaceflight crew.
Speaking on the sidelines of the Confederation of Indian Industry’s (CII) fifth edition of Foodcon 2016, Sharma said trials were being conducted on G Suit (a flight suit worn by aviators and astronauts who experience high levels of acceleration force, g).
It is designed to prevent black-out and g-LOC (g-induced loss of consciousness) caused by blood pooling in the lower part of the body when under acceleration against gravity, thus depriving the brain of blood.
“We are developing the food keeping in mind the requirements of aviators using the G-suit so that flow of blood to the brain is not blocked,” he said.
Talking of the space food, he said it would be more like toothpaste. “It will hold all solids converted into a paste,” said Sharma. Asked how long would it take to develop the food, he said it was at an inception stage.
ISRO has an MoU with IAM to conduct basic research on the physiological and psychological requirements for human space mission as a pre-project R&D. ISRO also has agreements with a Bangalore-based third party to develop spacesuits.

http://www.deccanchronicle.com/science/science/181216/space-age-isros-very-human-test.html... “We are getting ready for the pad abort test. It will happen soon,” says A.S. Kiran Kumar, Chairman, Isro. Simply put, the test flight will show how fast the crew could punch out from the rocket in the event of an emergency...
Simultaneously, Indian Space scientists are getting their act together for this ambitious mission, designing space suits, an environmental control and life support system on board the spacecraft, and a host of other critical systems needed for a safe journey of Vyomanauts.
All these systems and their tests will be completed before GSLV-III, the most powerful rocket designed by India, is “human-rated” or declared safe for a journey into Space by Indians. Current projections indicate the first journey of Indians onboard an indigenous rocket and from India soil could be in 2020-21.
Incidentally, all these critical systems and their tests are being accomplished with an infinitesimal part of the Rs 12,500 crore allocation sought by ISRO for the human spaceflight (HSF) programme. Reason: the government has maintained that it is not an “approved programme” and therefore, a small amount of about Rs 100 crore has been sanctioned for pre-project studies.
In short, these scientists intend to develop a fully-autonomous three-ton orbital vehicle (a spaceship) to transport a two-member crew to orbit and return to Earth after a few orbits to two days. The extendable version of the spaceship will allow flights up to seven days, rendezvous and docking capability with space stations.
Isro would receive assistance in crew selection and training from Russia under an agreement signed in March 2008. One option was a flight of an Indian onboard a Soyuz capsule in the run-up to an Indian mission, but that was dropped. The process of crew selection, too, awaits a nod from the government with the space agency likely to bank of the Indian Air Force and the Institute of Aerospace Medicine, Bengaluru, to pick potential candidates.

ISRO Chair Dr S Kiran Kumar says that ISRO has the capability & confidence to tackle development of a space station if the nation were to commit to such an undertaking.
http://economictimes.indiatimes.com/news/science/india-can-develop-space-station-says-isro-chief-as-kiran-kumar/articleshow/57258211.cmsIndian Space Research Organisation (ISRO) chairman A S Kiran Kumar today said the country has the capability to develop a space station, but it needed a long-term approach and an ambitious planning.
His comment follows ISRO display of technological prowess last week by launching 104 satellites in a single mission.
"We have all the capabilities to set up a space station. The day the country takes the decision, we will 'ok' the project. Just draw a policy and provide us necessary funds and time," Kumar said here.
Personally, I'm not sure ISRO should go that route, because it's so expensive. I don't see what significant benefits a dedicated space station could offer that a large manned vehicle couldn't.

ISRO has to initiate the Manned Space Program, because if is not yet initiated, the whole process will take longer. I always felt that had PSLV - XL - the most reliable Launch Vehicle of India - been manrated and necessary support materials been developed, ISRO could've sent a single astronaut by now with PSLV. But the Indian government of past dithered, even the current government run by so-called Space Buff who basks in Indian Space glory initiated by the preceding governments seem reluctant to go ahead with the allocation of fund for the Indian Manned Space Program.
Immediately after Rakesh Sharma became the first and till now the only Indian Astronaut to go to space on a joint Indo-Soviet Space Mission in 1984, the former USSR, with which India had a relationship on the path of utmost bonhomie, offered India many such joint mission. But unfortunately ISRO under the tenure of former ISRO Chairman Prof. U. R. Rao showed no interest in such offer.
Manned Space mission cannot get off the ground in 4-5 years after the fund allocation is sanctioned. Lot of supporting technology need to be developed. But the government has to give the go-ahead.

The reason the GoI has been dithering on a formal commitment for the manned space program is primarily its cost - the latest figure runs into Rs 20,000 crores, or $2 Billion if I did my math right. This would be as large as the entire yearly budget of ISRO! Then there would be legitimate questions whether such a program provides benefits proportional to such an investment in the near term, other than being a costly flag waving opportunity. On another level, the Finance ministry would be under pressure to keep a ceiling on govt spendings to keep fiscal deficit under limits and gain a favorable rating for the economy from international agencies.
That said, I do feel the manned space program needs to be pursued as a long-term investment. A lot would depend on the PM's interest on the matter, and if the GSLV MkIII test flight in April turns out to be a grand success, I'm hopeful of a favorable announcement from the Govt.
As for doing a quick bare bone, one man, Mercury-style flight in PSLV to mark our entry, what's the point if ISRO have to ditch it quick after that and then design a larger, more practical 3-person spacecraft riding on a larger rocket? It could be wastage of resources.
Just my 2 cents..

Here's another article featuring same comments from ISRO chief:
http://www.ndtv.com/india-news/india-can-develop-a-space-station-says-isro-chief-1661593I think the Space Tourism market could offer an answer, in regards to offsetting developmental and operational costs for manned spaceflight.
But as was just said, a single-man capsule can't do much, other than be symbolic. For Space Tourism, you need larger multi-man ships, to make things economical. And you'd probably also benefit from reusability, to make things more affordable still.
Once someone like Blue Origin starts to do Space Tourist flights in earnest, maybe it could open the eyes of India's space community, and inspire them to think of ways to pursue opportunities in the same market.
Antrix has been good at commercializing ISRO's capabilities thus far, so whatever manned spaceflight capability ISRO develops, I bet Antrix will find a way to market it.

On the Crew Escape System from
Annual Report 2016-17The performance demonstration test of Crew Escape System (CES) has been planned through Pad Abort Test (PAT) flight. PAT flight demonstrates the capability of CES to execute a ground based abort in case of an exigency at launch pad. In PAT flight, the test article (consisting of CM and CES) with a height of 14 m and lift-off mass of 12.5 t, is propelled at an acceleration of 10 g with the help of quick acting solid motors. Upon reaching a safe altitude and range, the crew module separates and safely lands in sea with the help of parachute based deceleration system. To enable quick acting, special purpose solid motors with high-burn rate propellant (being developed for the first time) and special features like reverse flow multiple nozzles and canted nozzles with scarffing have been designed and realised. Proof pressure test and propellant casting for motors have been completed. Facilities for vertical testing of solid motors and launch pedestal for PAT flight are being realised at SDSC. Wind tunnel tests for CES configurations have been completed. Crew Module (CM) structure required for CES test has been realised and successfully structural tested. The Pad Abort Test is expected to be completed by March 2017.
For demonstrating the Environment Control and Life Support System (ECLSS), integrated tests of Temperature & Humidity Control System (THCS) involving Air-Liquid Heat exchangers, Liquid-Liquid heat exchangers, pumps, space radiator, sensors and other accessories were successfully carried out. Preliminary ground based circuit for Cabin Pressure Control System (CPCS) was developed and realisation is in progress. A ground based Personal Hygiene Management System (PHMS) was configured and an engineering model has been realised.

ISRO should collaborate with other countries for human spaceflightHyderabad: Veteran space scientist K Kasturirangan has favoured India to pursue a collaborative model in its proposed human spaceflight venture to undertake the mission early in a cost-effective manner by leveraging proven capabilities in the field internationally.
"So, they (ISRO) need to really work out multiple strategies by which the goal can be achieved, and in those strategies how much of it should be ourselves, how much we should do with international collaboration component, and what's the optimum way in which we can reach the goal as early as possible with minimal investment because these are all investment-intensive and also they take their own time," he told PTI.
Not just funds, resources in terms of human and infrastructure, quite a lot of investment is needed if India is to do the venture alone, pointed out the former secretary in the Department of Space and ex-chairman of Space Commission.
"But the world has already moved there in that direction (human spaceflight) and therefore in the world today we have got quite a lot of capabilities available across globally. Our political relations are quite good with many of these countries (having such space capabilities) and so I think we should be able to develop models where we can optimally design a system by which we can move fast into the human spaceflight," Kasturirangan said.
However, he hasn't elaborated on the specific areas where foreign collaboration would help - like crew training, life support, safety systems, sending astronauts on other spacecrafts first for training etc. Or whether he favors a joint HSF program in partnership with other agencies like ESA or JAXA to spread the cost.
