New satellites to help Gaganyaan crew
Astronauts can be fully and continuously in touch with mission control throughout their travel
India plans to ring in its own era of space-to-space tracking and communication of its space assets this year by putting up a new satellite series called the Indian Data Relay Satellite System.
The IDRSS is planned to track and be constantly in touch with Indian satellites, in particular those in low-earth orbits which have limited coverage of earth. -

Sivan: may be just 1 astronaut on Gaganyaan maiden flight
https://www.hindustantimes.com/india-news/india-s-first-manned-mission-gaganyaan-may-take-1-astronaut/story-nh095IVken3trSu0V1wVnK.htmlQuoteSivan said that even though all four people will receive the complete training, it was likely that only one person would go to space during the first mission, which is scheduled for December 2021.
“We are designing the mission for three people to go to low earth orbit for seven days. However, whether we send two people or one person and whether they spend seven days in the orbit or one will be decided later on in the mission after the two unmanned flights. Usually, the first flight is very crucial and even countries such as the USA, Russia, and China sent only one person for the first time and for a very short time – one orbit, or one day, or even like the USA did only part of the orbit,” said Sivan. -

Yeah, I think that's been declared from the start, as per the original press conference. -

Why do I get the impression that ISRO are totally making this up, as they go along?
In August 2018 the crew was 3 (including a woman). Then they drew up some initial selection criteria, and quickly decided they didn't have any remotely qualified women. So, it then becomes 3 men, then 2 men, then 1 man. -

Gaganyaan launch window targeted for December 2021
source: PIB
Human Space Mission: Gaganyaan is targeted for December 2021. The Gaganyaan Programme has been approved by the Government of India. The design and configuration of major subsystem are finalized. The procurement and system/ subsystem realisation for tests and flight has commenced.
The crew selection and training process for Gaganyaan mission is progressing well including the training in Russia under Gaganyaan Mission.
GSLV Mk III launcher which is ISRO’s heavy lift launcher is identified for Gaganyaan mission. It has requisite payload carrying capacity for Orbital module in desired elliptical orbit. Process for human rating of GSLV Mk-III is progressing well.
ISRO has wide experience in technological areas with respect to Launch vehicle, spacecraft management, ground infrastructure etc. ISRO has taken steps for human rating of existing systems to ensure crew safety. In certain areas where ISRO lacks experience such as Human centric systems, crew training, crew recovery etc., ISRO is planning to collaborate with national and international agencies. MoUs in this regard have already been signed with DRDO labs, Indian Air Force and Russian space agency.
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.

This image looks like a lot of.... artistic license.
Those solar panels cannot articulate.
The windows look like they stand proud, including what would be two at ninety degrees to the hatch which we can assume would be “up” during reentry. They would protrude into the airflow.
That could be a featureless docking hatch up front, but they don’t have an immediate need for a hatch, or something to which to dock. It could be an external attachment to the LAS.
There are no significant nozzles on the single visible visible ACS thruster cluster (between the edge of the heat shield and the SM.)
If they had a full design, which would be pretty much necessary for a test flight in a year, they should have a CAD visualization with more and better details.
Given their currently stated goal of a manned flight in 2021, K210’s prognostication of 2024 would put the scale factor for “Indian Spaceflight Time” at 2.5:1
That’s comparable to others including SpaceX.
It’s a race between Gaganyaan and Orion. 😉 -

I'm not sure that's quite what happened. When Modi initially announced Gaganyaan, he simply said that someone - be it a man or woman - would be taking the Indian flag to space. His was a general announcement at the political level, and not really concretely specifying how many would go on that flight.
ISRO then said of Gaganyaan that it would strive to have the capability to put up to 3 astronauts in space for up to a week. That wasn't a declaration that it would be exactly 3 astronauts and a week-long mission, simply their statement that they wanted to have that level of capability on offer for the maiden crewed flight, and that the actual decision on how many and for how long would be taken later on.
When I quoted Sivan just now, I put the "may be" because he wasn't formally declaring how many would fly and for how long - he was just giving his informed speculation, which we can take as a hint. One problem is that the Indian media are so hungry to cover the story that they'll dig up any statements from anyone they can find, and play it up as factual reality. So I guess we have to sift the wheat from the chaff. -

Indian astronauts to arrive in Russia for training in February
They will undergo training on Russian Soyuz spaceships
SAMARA, January 30. /TASS/. A group of Indian astronauts will arrive in Russia in February to undergo training, Chief of Russia’s Cosmonaut Training Center Pavel Vlasov announced on Thursday.
"They are arriving in February and the program is intended for one year and a half," Vlasov said.
The Indian astronauts will be training in ‘the spacecraft commander’ and ‘spacecraft flight engineer’ specialties. They will undergo training on Russian Soyuz spaceships.
It was earlier reported that four representatives of India would undergo a selection procedure and training at Russia’s Gagarin Cosmonaut Training Center.
India’s Prime Minister Narendra Modi announced in August 2018 that his country would independently send the first national crew into orbit by 2022 when the country celebrates the 75th anniversary of its independence. So far, the flight is scheduled for the end of 2021. Before that, two spaceships are expected to be launched in their uncrewed version. The first Indian manned mission is called Gaganyan (from the Sanskrit word ‘gagana’ - the sky), i.e. the sky vehicle.

That literally looks like something from Kerbal Space Program, not even joking. The little RCS pod and the antenna look like they're lifted straight from the game's default parts list. Even the way the protrusion for the docking port on top looks is another feature of most capsules in Kerbal. -

The latest pics from the IAA symposium show the crew module as having 4 solar panels, Skylab-style:
(I wonder why so many solar panels are needed? Would a crewed vehicle be expected to have such high electrical power requirements?)
[Edit zubenelgenubi: 3rd, 4th, and 5th attached images]
There is also an exhibit for the proposed Indian space station:
[Edit zubenelgenubi: 6th attached image]
So what's the technical name for that dark gray spherical junction module that connects the other modules? A hub? Since one purpose of the space station program is to learn how to do EVA, then I'm wondering if the hub could itself serve as an airlock for egress/ingress? Or is that impractical, as it's situated between the 2 hab modules and linking them together?
And what's that white cylindrical module projecting downward from the hub in a vertical orientation? Is it perhaps a storage compartment? Why does it look different from the other modules? Why does it have what appears to be a larger diameter? Is it white and reflective because it's supposed to hold volatiles/cryogens, and needs to ward off solar heating? The purpose of the hub seems to be to allow traversal, so I don't see why you'd attach a storage tank for liquids/gases/volatiles/cryogens to a hub like that. Alternatively, maybe it's just a dummy placeholder for further unspecified modules.

Pleased to see India looking at building their own space station. That's the next logical step after launching a capsule.

Node.QuoteAnd what's that white cylindrical module projecting downward from the hub in a vertical orientation?
That might be an inflatable module, otherwise India is going to need to need a pretty big fairing to launch it! -

Hmm, maybe it's just a generic placeholder meant to represent other unspecified future modules, including from potential international collaborators. Perhaps it's just there to highlight the multi-port geometry of the node/hub.
Otherwise, it doesn't seem to have the same look as a Bigelow or SNC or Transhab type inflatable modules.
