Cabinet approves Indian Human Spaceflight Initiative: Gaganyaan Programme

The Union Cabinet chaired by Prime Minister Shri Narendra Modi has approved the Gaganyaan Programme with demonstration of Indian Human Spaceflight capability to low earth orbit for a mission duration ranging from one orbital period to a maximum of seven days. A human rated GSLV Mk-lll will be used to carry the orbital module which will have necessary provisions for sustaining a 3-member crew for the duration of the mission. The necessary infrastructure for crew training, realization of flight systems and ground infrastructure will be established to support the Gaganyaan Programme. ISRO will collaborate extensively with National agencies, laboratories, academia and industry to accomplish the Gaganyaan Programme objectives.

Expenditure:
The total fund requirement for the Gaganyaan Programme is within Rs.10,000 crore and includes cost of technology development, flight hardware realization and essential infrastructure elements. Two unmanned flights and one manned flight will be undertaken as part of Gaganyaan Programme.

Benefits:
  • Gaganyaan Programme will establish a broader framework for collaboration between ISRO, academia, industry, national agencies and other scientific organizations.
  • It This will allow pooling in of diverse technological and industrial capabilities and enable broader participation in research opportunities and technology development benefitting large number of students and researchers.
  • The flight system realization will be through Industry.
  • It is expected to generate employment and train human resources in advanced technologies.
  • It will inspire large number of young students to take up science and technology careers for national development.
  • Gaganyaan Programme is a national effort and will involve the participation of the Industry, Academia and National Agencies spread across the length and breadth of the country.

lmplementation Strategy and Targets:
Gaganyaan Programme will be a national effort in collaboration with Industry, Academia and other scientific agencies and laboratories as stake holders along with ISRO. ISRO will be responsible for realizing the flight hardware through Industry. National agencies, laboratories and Academia will participate in crew training, human life science technology development initiatives as well as design reviews. First human space flight demonstration is targeted to be completed within 40 months from the date of sanction. Prior to this, two unmanned flights in full complement will be carried out to gain confidence on the technology and mission management aspects.

Impact:
  • The programme is expected to spur research and development within the country in niche science and technology domains.
  • Huge potential for technology spinoffs in areas such as medicine, agriculture, industrial safety, pollution, waste management, water and food resource management etc.
  • Human spaceflight programme will provide a unique micro-gravity platform in space for conducting experiments and test bed for future technologies.
  • The programme is expected to give impetus to economic activities within the country in terms of employment generation, human resource development and enhanced industrial capabilities.
  • Human Spaceflight capability will enable India to participate as a collaborating partner in future Global space exploration initiatives with long term national benefits.

Background:
ISRO has completed the development of launch vehicle GSLV Mk-lll which has the necessary payload capability to launch a 3-member crew module in low earth orbit. ISRO has also tested the crew escape system which is an essential technology for human space flight. The aerodynamic characterization of crew module has b3een completed as part of GSLV Mk-lll X mission flight. Elements of life support system and Space suit also have been realized and tested. In addition, the orbital & re-entry mission and recovery operations have been flight demonstrated in Space Capsule Re-entry experiment (SRE) mission. ISRO has developed and demonstrated most of the baseline technologies essential for undertaking human spaceflight mission. Globally also, there is a renewed interest in undertaking manned exploration initiatives.

PSLV-C42 launches 2 foreign satellites



The Polar Satellite Launch Vehicle (PSLV-C42) of Indian Space Research Organisation (ISRO) today (16 Sept 2018, Sunday) successfully launched two satellites -- NovaSAR and S1-4 -- from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota here.

The PSLV-C42 lifted off from the First Launch Pad of SHAR at 10.08 pm (IST). Both satellites were injected into the Sun Synchronous Orbit, about 17 minutes later, at an altitude of 583 km.

The satellites belong to UK-based Surrey Satellite Technology Limited (SSTL), which has a contract with Antrix Corporation Ltd, the commercial arm of ISRO.

NovaSAR carries S-band Synthetic Aperture Radar (SAR) and an Automatic Identification Receiver payloads. The satellite applications include forestry mapping, land use and ice cover monitoring, flood and disaster monitoring and maritime missions. It will be operated from SSTL’s Spacecraft Operations Centre in Guildford, UK.

S1-4 is a high resolution earth observation satellite meant for surveying resources, environment monitoring, urban management and disaster monitoring.

This was the 44th flight of PSLV and the 12th flight of the Core Alone version of the vehicle. Core Alone is its lightest version without the six strap-on motors. It is used for launching smaller payloads.

The PSLV launch vehicle consists of four stages, each of which is a self-contained vehicle capable of functioning independently with own propulsion systems.

During the previous launch (PSLV-C41, 12 April 2018), the ‘XL’ version of PSLV with six strap-on motors was used. The vehicle successfully launched the IRNSS-1I navigation satellite to a Sub-Geosynchronous Transfer Orbit.

Preparations began at Sriharikota in mid-July with the process of vehicle integration setting the tone for the launch. Many centres of ISRO contributed to this mission with the vehicle being designed and developed by Vikram Sarabhai Space Centre, Thiruvananthapuram.

The second and fourth stage liquid engines came from Liquid Propulsion Systems Centre, Thiruvananthapuram and ISRO Propulsion Complex, Mahendragiri (TN).

The vehicle’s guidance system is from ISRO’s Inertial Systems Unit, Thiruvananthapuram, while SDSC SHAR was responsible for solid motor preparation, vehicle integration and launch infrastructure. ISRO’s Telemetry Tracking and Command Network provided tracking support.

ISRO Chairman Dr K Sivan congratulated the team soon after the successful mission.

“I am extremely happy that the PSLV-C42 precisely launched two of our customer satellites at 583 km orbit. This was unique night mission executed for the first time by us. The PSLV has proven yet again as a user-friendly vehicle in all aspects. The credit goes to the entire ISRO team and industries. This success will give added energy for industries to make PSLV by themselves. We are going to have 18 missions in the next six months, virtually one launch every two weeks,” Dr Sivan said.

Thousands of skilled personnel from ISRO and industries, including many youngsters, played a crucial role in this mission. The Project Director of PSLV is R Hutton, who was also the Mission Director.

“The PSLV-C42 marks the latest technology and commercial collaboration between India and the UK with the launch of the combination of high resolution optical and radar (SAR) satellites from us,” says Sir Martin Sweeting, Group Executive Chairman, SSTL

As on date, ISRO has launched 239 foreign satellites of 28 countries.

India's heaviest rocket GSLV MkIII-D1, powered by cryogenic engine, successfully places GSAT-19 into orbit



New Delhi: The Indian Space Research Organisation (ISRO) on Monday added another feather to its already flooding cap by successfully launching its heaviest homegrown rocket until date, the GSLV-Mk III, from the spaceport of Sriharikota.

Addressing the Media immediately after the launch, ISRO chairman AS Kiran Kumar has confirmed that the GSLV MKIII D1/GSAT-19 mission has been successful.
