Weeks, eh? How long would a typical human spaceflight mission be expected to last? The crew capsule doesn't seem large enough to do a mission that lasts weeks. Oh well, must be the usual requirement for over-design, I guess.

The Indian Space Research Organisation (ISRO) is focusing on developing a manned space vehicle to carry a crew of two or three members to the low earth orbit and return safely to the earth, said Unnikrishnan Nair, Project Director, Human Space Flight Project, ISRO.
Delivering a lecture after launching an online portal “Direct” of the Electronics and Communications Engineering at the National Institute of Technology-Tiruchi here on Wednesday, he said the ISRO had been working very hard for the launch of manned space vehicles. Various units were working for the successful launch. All aspects, including safe launch, effective ground monitoring, cabin crew safety, living space capsule model, and contingency plans were closely studied. While stating that successful launch was the prime objective of manned space mission programme, ISRO was working out modalities for the safety of the crew members if anything went wrong during the launch. The launch vehicles should be intelligent enough to safeguard the crew members. -

In another article(ToI) about this eventQuote
Narrating the attempts made by Isro to develop a cost-effective spaceflight for its manned space mission, he said the early manned space capsule used by Russia can only be used one time.
He said a reusable space vehicle is in the making for the manned space mission of Isro.
He drew the comparison with Soyuz capsule and highlighted its non re-usability. He can't be talking about RLV-TD or other unmanned concepts. Could he mean that Indian crew capsule is intended to be reused !

"The space-suits have been done in Vadodara by a private firm. It is already been tested and verified. The first thing is to make sure that you are able to control the environment for the person wearing the suit in terms of humidity, temperature and oxygen"
"Primarily, all the activities including that of design of the chamber are being done in Trivandrum, with some work being done in other places. For example, in Ahmedabad, some of the sensors and lighting systems for the chamber is being done"

Isn't the reason for white spacesuits to reflect heat from the sun during spacewalks? Russia, China, as well as the US use white suits. I noticed this one was red or orange.

It appears to be similar to Sokol flight suit one difference I see is that it has electric cables running out from its right . I am not sure if this is the final design that is being made by that firm in Vadodara though. -

Yeah, even when it comes to pics of the Indian space capsuled, I wondered why the capsule wasn't white to reflect the Sun's rays more. It seems like the orange/brown color would cause it to absorb more solar heating.

Manned spaceflight not an immediate priority, says ISRO chief

It would be shameful of ISRO not to have taken up the initiative of manned space program now after having started the space program in the mid 60s. Had PSLV- the ISRO workhorse launch vehicle - been man rated, it could have easily taken a single Indian Astronaut to space as it has low earth orbit payload capacity of over 3 ton ( 3250 Kg / 7200 lb ). But weirdly ISRO never made any intention of using PSLV as a single astronaut manned space flight program. After the Space Capsule Recovery Program 1 that was done in 2007, ISRO did not follow up with Space Capsule Recovery Program 2 that would have been precursor to initiating Manned Space Program. Early in the Space Race between the USA and the USSR, neither of the countries waited for a spacecraft to be developed with heavy launch mass.
Lets take a look at mission features of the Project Mercury 2nd Flight that took John H. Glenn, Jr to space, thus making him the first US astronaut to make an orbital flight.
Mission duration 4 hours, 55 minutes, 23 seconds
Distance travelled 121,794 kilometers (65,763 nautical miles)
Orbits completed 3
Spacecraft Features
Spacecraft Mercury No.13
Manufacturer McDonnell Aircraft
Launch mass 1,224.7 kilograms (2,700 lb)
Crew 1 [ John H. Glenn, Jr ]
Launch date February 20, 1962, 14:47:39 (1962-02-20UTC14:47:39Z) UTC
Rocket Atlas LV-3B 109-D
Landing date February 20, 1962, 19:43:02 (1962-02-20UTC19:43:03Z) UTC
Orbital parameters
Regime Low Earth orbit
Perigee 149 kilometers
Apogee 248 kilometers
Period 88.47 minutes
If we take a look at the US manned space program that began with the Project Mercury, US used Atlas LV-3B, Atlas D Mercury Launch Vehicle or Mercury-Atlas Launch Vehicle to send an astronaut. This man rated expendable launch vehicle - derived from the SM-65D Atlas missile - was used in the US Project Mercury Manned Space Program to launch Astronauts into low Earth orbit. It has a launch mass of 120,000 kilograms (260,000 lb) against 3,250 kilograms (7,200 lb) of PSLV and has LEO payload capacity of 1,360 kilograms (3,000 lb) against 3,250 kilograms (7,200 lb) of PSLV. All ISRO required was to man rate it, develop all the support system and push the Indian Government to give the go ahead. Despite starting a Space Program nearly 50 years ago and launching over fifty foreign satellites though not very large, ISRO would find itself in an awkward and disgraceful situation if lesser known countries such as Iran preempts India to send astronaut to space even on a sub orbital mission with its rocket derived from missiles procured clandestinely from North Korea and being passed off as their own stuff and being used as intimidation to wipe out its enemy.
But who will listen to this plea of mine ? ISRO is to blame itself for this situation. Right after the journey of Rakesh Sharma, the first and only Indian to go to Space with Indo Soviet space mission, former USSR during its bonhomie relation with India was offering ISRO space flight offers one after another. But ISRO not only turned down all of them but also prevented Indian Air Force from grabbing those offers. Then after the sudden demise of Rajiv Gandhi, India got a number of spineless, debilitating governments that did not have any urgency or motivation to send Indian astronauts to space after PSLV became a workhorse launch vehicle. This new government is following in the same footsteps. But instead of sanctioning manned space program and other scientific project such as LIGO India, this government - to justify its so called nut bolt screw driver Make in India Initiative - is basking in the glory of successful mission sanctioned by preceding governments such as Mars Orbiter Mission, Astrosat, back-to-back GSLV MK 2 successful mission, GSLV MK 3 sub orbital mission with crew module etc.
Can someone in this forum remind the Indian PM trough twitter if he has forgotten to sanction the manned space program as his science minister Dr. Harsh Bardhan keeps on saying that India would launch its first astronaut in space by 2021 ?Quote
There is also evidence of some crosstalk in the Modi government. Science minister Harsh Vardhan continues to egg on the scientific community, repeatedly asserting that “India will launch its first astronaut in space by 2021. But the Modi government is yet to approve the human space flight program that would cost upwards of Rs. 12,500 crore.
Scientific community has mixed feelings on Narendra Modi's first year as Prime Minister - The Hindu:

There are a lot of critics of the Human Spaceflight Program from India's traditional scientific establishment - they feel that this is a vanity project which will waste a lot of money while providing little scientific or material return to the Indian people.

They are perfectly entitled to their opinion but they should realise by now that Spaceflight isn't just about science but also public outreach & politics. -

Agreed.
Soft power is important in international politics. India joining the exclusive human spaceflight club would be a boost to India's international prestige. -

INDIA’S MANNED SPACE MISSION, NOT IN NEAR FUTURE … OR NEVER?Quote
Even if Centre okayed it now, it would take many years for mission to materialise; Institute of Aerospace Medicine remains clueless about training facility for astronauts
Awaiting the Union government's nod but already facing other delay-inducing obstacles, the much-touted manned space mission of India will not take place in the near future - not in 2017 as was expected; not even by 2021 as reported recently. In fact, with the prolonged delays, there is a fair chance that the mission may not take off at all.Quotewith the prolonged delays, the space scientists are also bracing for the mission not to take off at all, but are not saying so openly at present. They feel ultimately it may be preferred to send Indian astronauts on board US or Russian launchers for deep-space missions rather than send them on indigenous ones.

We are a country with a very challenging socio economic conditions and limited finances, henceforth we should invest in projects on a priority basis.

Space capsule recovery experiment => SRE......hhmmm so we gonna have some space suit experiment in SRE-2?? is there enough space for such experiment??
May the Force be with ISRO

When asked about manned space programmes, he said it was for the government to take a decision. "Manned programme will be done only after the government gives permission. We have not got any clearance so far."
"However, ISRO is working on various projects and critical technologies like crew module, creating an environment inside the crew module for people inside to survive and also space suit.
"Some activities are going on but finally, the government has to make up its mind and then tell whether we should take up manned mission or not," Kumar said.
