Human Space Flight Centre (HSFC) was formed on January 30, 2019 with a vision of implementing a sustained and affordable human and robotic programme to explore the Solar system and beyond and extend human presence across the solar system, starting with human spaceflight to low earth orbit and return.
Gaganyaan, maiden manned mission of India, is the first project of HSFC, challenging both in terms of technological complexity as well as timeline. Engineering systems and human centric products for Gaganyaan involves design, development and realisation of technologies in various domains of bioastronautics, human space sciences and space habitat systems. The project calls for a paramount of activities to be carried out concurrently across all ISRO Centres. Several national agencies, academia and industries are also involved in developing these systems. As per the mandate of Gaganyaan, two unmanned missions will be undertaken prior to the manned mission.
The four Indian astronauts who were selected for Gaganyaan have completed generic crew training in GK, Russia and will be undergoing mission specific training in Astronaut Training Facility which is coming up in Bangalore.
LPSC plays a significant role in Gaganyaan programme which aims to develop indigenous capability towards demonstrating human spaceflight to Low Earth Orbit. Towards this human rating of C25 & L110 stage and demonstration of margin of operation is envisaged. Design and development of Crew module propulsion system and Service module propulsion for the orbital module with bi-proprellant propulsion system is envisaged.
In addition to this, LPSC is also contributing towards development of ECLSS major subsystems including Cabin Pressure Control system (CPCS), control components and assembly of Thermal and Humidity control system & Human Metabolic Simulator and various types of umbilicals for the Orbital Module Propulsion System (OMPS). In order to demonstrate the Crew Escape System performance a Test Vehicle has been configured and LPSC has the lead role in design, development and realization of the Test Vehicle propulsion system. LPSC is also delivering sensors for this prestigious programme. In all the above systems, design of components has been completed and design documents have been released. Currently the developmental activities, fabrication, testing and qualification are in progress.

https://www.hindustantimes.com/india-news/38-years-since-the-day-indian-dreams-soared-into-space-101648835402763.htmlNew Delhi: When cosmonaut Rakesh Sharma was asked by the then Indian Prime Minister Indira Gandhi, “Upar se Bharat kaisa dikhta hai (How does India look like from space?),” the response was memorable: “Saare jahan se accha (better than the whole world)”. That statement from 38 years ago made every Indian proud of their nation.
On April 2, 1984, Indian Air Force pilot Rakesh Sharma made history by becoming the first Indian to travel to space. He was part of the Soviet Union’s Soyuz T-11 expedition, a joint mission of the Indian Space Research Organisation (Isro) and the Soviet Intercosmos space programme.
Sharma spent seven days, 21 hours and 40 minutes in space, accompanied by two Russian cosmonauts, and added fuel to the country’s space aspirations in the years to come.
“I orbited the Earth and our scientists carried out several experiments using our equipment. In that sense, it was an opportunity well-utilised,” the now 73-year-old said about his mission.

https://timesofindia.indiatimes.com/city/ahmedabad/2-satellites-to-keep-contact-with-gaganyaan-intact/articleshow/90630885.cms... two communication satellites will be stationed at 120 degrees apart so that even when the module will be behind the Earth from India’s point of view, it will not lose connection.
The orbital module consists of crew module and service module. Atop the crew module will be crew escape system with boosters — a first for any ISRO rocket. The modules will be powered to space by GSLV Mk III. To test its systems, two missions will be launched which will mimic everything, except it won’t have any human crew.
The present plan is to put the module in 400km orbit around Earth, which is identified as LowEarth Orbit (LEO).

https://timesofindia.indiatimes.com/india/2-gaganyaan-abort-tests-in-august-december-relay-satellites-next-year/articleshow/90688885.cmsIsro chairman S Somanath told TOI: “We are looking to schedule the first abort mission on the new vehicle in August and the second one in December. The relay satellites have not been scheduled for this year.”
Isro’s target is to demonstrate the first or abort conditions in August, wherein, it will intentionally cause an anomaly and allow the crew module to come out of it, do the tumbling manoeuvres, deploy parachutes, and land in a designated spot on the sea before being recovered.
Work on the 2,275-kg data relay satellites — Indian Data Relay Satellite System (IDRSS) — is ongoing. On April 4, Isro received the satellite structure built by defence PSU HAL, but a lot of work is still pending on the satellites.

https://timesofindia.indiatimes.com/india/gaganyaan-proof-of-concept-to-use-amazon-ground-stations-done-no-final-decision-yet/articleshow/91451417.cmsGaganyaan: Proof-of-concept to use Amazon ground stations done; No final decision yet
BENGALURU: Isro, which is looking to firm up agreements for a network of ground stations from around the world for telemetry, tracking and command (TTC) operations for Gaganyaan, has completed a proof-of-concept (PoC) for utilising Jeff Bezos’ US-based Amazon Web Services’ (AWS) ground stations.
The PoC was demonstrated by testing one of the AWS ground stations for carrying out TTC operations of the SARAL satellite. Isro chairman S Somanath told TOI: “We have done the tests to see whether we can use their ground stations but no final decision has been taken as yet.”
“A ship-borne terminal planned for TTC coverage in the ascent phase in order to provide better elevation compared to existing 8° elevation from Port Blair station. The IDRSS-2 (relay satellite) is planned to be relocated from 148° to 240° in order to provide 100% visibility coverage for the mission,” as per Isro’s plans.
As reported earlier by TOI, Isro is looking to use at least 40 ground stations — Indian and those belonging to other countries — to track astronauts when they travel around Earth aside from launching two relay satellites.

ISRO successfully tests large human rated solid rocket booster for the Gaganyaan programme
ISRO successfully completed the static test of a human-rated solid rocket booster (HS200) for the Gaganyaan Programme at Satish Dhawan Space Centre (SDSC), Sriharikota, Andhra Pradesh on May 13, 2022, at 7:20 AM local time. HS200 rocket booster is the human-rated version of the well-proven S200 rocket booster of GSLV Mk III satellite launch vehicle, popularly known as LVM3. The successful completion of this test marks a major milestone for the prestigious human space flight mission of ISRO, the Gaganyaan, as the first stage of the launch vehicle is tested for its performance for the full duration. The event was witnessed by Shri S Somanath, Chairman, ISRO / Secretary, Department of Space and Dr. S Unnikrishnan Nair, Director, VSSC along with other ISRO scientists. Design and development of the HS200 booster were completed at Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram and propellant casting was completed at SDSC, Sriharikota.
The S200 motor which is the first stage of the LVM3 launch vehicle intended for launching a 4000 kg class of satellites to Geosynchronous transfer orbit, was configured as a strap-on rocket booster. Based on the successful launch pedigree of this launch vehicle including the Chandrayaan mission, the LVM3 has been identified as the launcher for the Gaganyaan mission. For the manned space mission, LVM3 launch vehicle underwent improvements stipulated by the requirements of human rating. Accordingly, a host of design improvements that were aimed at increasing the safety and reliability of various systems were implemented in the S200 booster like all other systems. These include additional safety features for motor case joints and robust insulation and ignition systems. The control system used in this booster employs one of the world’s most powerful electro-mechanical actuators with multiple redundancies and safety features. The system is fully indigenously designed and developed by ISRO in participation with various industries spread across the country. Despite the restrictions imposed by the pandemic, ISRO could complete the entire design, development, realization and testing process within a short span of two years.
The HS200 booster loaded with 203 tons of solid propellant was tested for a duration of 135 seconds. The 20 m long and 3.2 m diameter booster is the world’s second-largest operational booster with solid propellant. During this test, about 700 parameters were monitored and the performance of all the systems was normal. With the successful completion of this test, ISRO marches one more step closer to Gaganyaan Programme. Out of the three propulsion stages of LVM3, the human-rated versions of the second stage known as L110-G loaded with liquid propellant and the third stage C25-G with cryogenic propellant are in the final phase of qualification including tests with static firing. Gaganyaan programme, the most prestigious scientific endeavour of India is steadily progressing towards its final goal of taking an Indian to space and bringing him safely back.
