Hit by disruptions due to the coronavirus pandemic, the launch of India's unmanned space mission under the first leg of Gaganyaan, planned for December 2020, is likely to be delayed, sources said.
It was part of the two unmanned missions to be undertaken by the Indian Space Research Organisation ahead of the planned launch of India's maiden human spaceflight under 'Gaganyaan' in December 2021.
The likely delay in the first unmanned mission was recently conveyed to the Space Commission, the apex policy-making body on space related issues.

Two years ago, Prime Minister Narendra Modi had announced the human space mission in his Independence Day address.
The Gaganyaan mission aims to send a three-member crew to space for a period of five to seven days by 2022 when India completes 75 years of Independence.
The ISRO had started planning for the mission accordingly. The first unmanned mission was planned in December 2020, the second unmanned mission in June 2021.
The final and the main component, the manned mission of Gaganyaan, was scheduled six months later in December 2021, much before the 2022 deadline.
ISRO
had earlier indicated that there would be a delay in several missions as the space body's work has been hit by disruptions due to the coronavirus pandemic.
Among the major projects that have been affected are Chandrayaan-3 and Gaganyaan. Chandrayaan-3, the third mission to Moon, was scheduled later this year.
The sources said that efforts are on to stick to the deadline of 2022 for launching the human space mission.
"We will not be able to meet deadline for the December 2020 launch of the unmanned mission. The coronavirus pandemic has led to several disruptions. This was also recently conveyed to the Space Commission," a source said.
The sources added that staff members from ISRO's different centres were infected. Only essential and process related work is on. Also, the related industry has been affected.
Even the training of four astronauts in Russia was hit due to the pandemic. However, the training has now resumed.
"Even if we are not able to launch the manned mission by December 2021, we have eight months to cover up for the time we have lost," the source said.
The spacecraft will be placed in a low earth orbit of 300-400 kilometres. The total programme cost is expected to be less than Rs 10,000 crores.
In June, Jitendra Singh, Minister of State in the Prime Minister's Office, had said even though because of the Covid-19 pandemic, the training of four Indian astronauts in Russia had to be halted, yet the opinion of Chairman ISRO and the scientific team is that there is a cushion period kept both in the training programme and launch deadline.
The training of astronauts has now been resumed and the launch is scheduled to take place as planned, before the 75th anniversary of India's independence in 2022, he had said.
Four astronauts selected for the country’s first human spaceflight will return from Russia in March and undergo training modules designed by the Indian Space Research Organisation (Isro) for the mission slated for December 2021.
While in Russia, their training is helping them get accustomed to conditions in space — the US, Russia and China are the only three countries to have conducted human spaceflights — the four astronauts will undergo mission-specific training back home.
“The four astronauts, who had been selected from a pool of Indian Air Force pilots, are currently undergoing basic training in GCTC (Yuri Gagarin Cosmonaut Training Centre) in Russia. They will be back by March next year. They will then receive specific training in India, for which the simulators have been defined. These are the areas where the industry will be contributing in a rich way to realise the simulators,” Dr Unnikrishnan Nair, director, Human Spaceflight Centre of Isro, said.
There will be three main parts to the training in India: a module on the overall project, a module for crew members, and a module on the flight hardware and software.
“Each one is more and more complex (than the previous one),” he said at the International Space Conference and Exhibition organised by Confederation of Indian Industry in association with Isro and its other arms.
India’s first human spaceflight mission, Gaganyaan, has been designed to carry three Indian astronauts to the low earth orbit — an orbit of 2,000km or less — for a period of five to seven days.
But Isro chairperson Dr K Sivan told HT earlier this year that two unmanned flights prior to the final mission will determine whether just one or two crew members will be taken to space and whether the crew will be there for the entire duration, or for just one day, or just over two hours.
Isro has planned the first unmanned flight in December 2020, the second in July 2021, and the first human spaceflight mission in December 2021 — much ahead of the August 15, 2022, deadline set by Prime Minister Narendra Modi. However, the timeline could be affected due to the Covid-19 pandemic, according to officials.
Before the first unmanned flight, Isro needs to complete at least three major tests — an air drop test for the parachute system that will demonstrate the ability to successfully recover an orbiting space capsule; a flight of the test vehicle; and an abort test to demonstrate the escape of the crew in case of an emergency at the launch pad.
Isro has also shortlisted six experiments that will be carried out in space aboard the first unmanned flight under the Gaganyaan mission. This includes four biological experiments – a study on changes in kidney stone formation in drosophila melanogaster (the common fruit fly), the study of SIRT1 gene in it, microbial contamination, and co-crystallisation under microgravity conditions.
Nair said Gaganyaan will be the first of Isro’s human spaceflight mission, which will be expanded to the exploration of other planets and also the moon in the future. For this, Isro will partner with the industry and academia to develop technologies such as construction in space, tele-robotics and artificial intelligence.
ISRO’s heavy lift launcher, GSLV MkIII is identified for the Gaganyaan Mission and the process for human rating of GSLV MkIII is in progress. The high thrust solid propellant strap-on boosters S200 play an important role in the Human Rated GSLV MkIII. In order to human rate the booster, many new design features have been introduced in the hardware.
In yet another successful industry collaboration, the first critical booster segment of the motor case with a diameter of 3.2 meter, 8.5 meter in length and weighing 5.5 tons has been indigenously developed and delivered by L&T to ISRO. This is the first step towards the Unmanned Space Mission and was flagged off on November 13, 2020 by Dr. K. Sivan, Secretary, Department of Space and Chairman ISRO, and Shri. Jayant Damodar Patil, Director & Senior EVP Defence & Smart Technologies, L&T.
I think more safety features. So, that crew remains safe as we are using a rocket with solid rocket booster.So, Gaganyaan-1 (unmanned test) is around the corner in early 2021. Not sure which new design features are there in new boosters anyway.

S200 Motor case for Gaganyaan first Unmanned Mission Flagged Off
Notwithstanding the impact of the COVID-19 global pandemic on all sectors, Larsen & Toubro has once again delivered the first hardware, a booster segment, for Gaganyaan Launch Vehicle ahead of schedule. This was done through a virtual flag-off ceremony which was presided over by Dr K Sivan, Chairman, Indian Space Research Organisation (ISRO), and Jayant Patil Whole-time Director and Member of L&T board, and other members of the scientific community.
More about the critical components for HSFPAccording to a company release L&T is playing a vital role in powering ISRO’s Human Space Flight Program (HSFP). It has been working with ISRO for almost five decades and has been involved in the production of a range of hardware for every mission including the Mangalyaan and Chandrayaan missions.
For the Human Space Mission, ISRO says the heavy-lift GSLV Mk III launcher has been identified for Gaganyaan mission.
Why? Because it has the requisite payload carrying capacity for launching an Orbiter module in a desired elliptical orbit.
Booster segmentAnd the S-200 forms the solid propellant booster for this launch vehicle.
What other components is L&T building for ISRO?Using special space-grade material the Middle Segment of the world’s third-largest solid propellant rocket booster – ‘S-200,’ with zero-defects has been produced at L&T’s Powai Aerospace Manufacturing Facility. GSLV Mk III is the vehicle used to launch the Human Space Flight orbiter and crew module. The launch of the GSLV is aided by the S-200 strap-on solid rocket booster. S-200 is the third-largest solid booster in the world next to the solid boosters of the Space Shuttle and Ariane-5. S-200 solid booster contains 200 tonnes of solid propellant in three segments – Head end Segment, Middle Segment & Nozzle End Segment. The motor measures 22 meter in length and 3.2 meter in diameter. L&T has build all the three motor segments of the S-200. For the Gaganyaan mission, the booster is built with much more stringent tolerances and other safety and reliability features than the standard S-200 booster.
What kind of material is being used?L&T manufactures a number of critical flight hardware, sub-systems and assemblies for GSLV Mk-III at its facilities specifically dedicated for ISRO’s requirements. These include S200 Segments (Head End, Middle & Nozzle End Segments); Ogive Payload Fairing System; Thrust Block Sub-assembly; Umbilical Plates; and Honey Comb Deck Panels. L&T also manufactured satellite subsystems like Reflector Deployment Mechanisms (RDM) and Solar Array Deployment Mechanisms (SADM).
‘Diwali gift to the country’In realising this program L&T has worked on special high strength alloy steels like 15cdv6, MDN 250 which are specially made for the space program at Midhani. The program also uses special grade stainless steels, light aluminium alloys, titanium alloys, exotic material like high nickel alloys and high performance composite materials such as carbon phenolic, glass epoxy and honeycomb cores. L&T has also supported the development of space-grade materials by supplying equipment for the Titanium Sponge plant and also a 2000 MT plate stretcher for stabilising space-grade aluminium plates.
Dr K Sivan, Chairman, ISRO, complimented the L&T and ISRO teams for the maiden delivery as a ‘Diwali Gift’ to the country, and their hard work on realizing the flight hardware ahead of schedule. And also for maintaining the highest quality standards required for a Human Space Flight Mission. JD Patil, Whole-Time Director and Senior Executive Vice President (Defence & Smart Technologies), L&T, said, “We are confident that together with ISRO scientists, L&T engineers and technicians will fulfill the aspirations of the nation.”
It is very unpleasant that due to the pandemic, development is stalled in all areas. Although medicine is developing now, the shares of pharmaceutical companies that have developed COVID vaccines have skyrocketed. But it's a pity that both the sending of rockets into space and the release of films are delayed. I am already silent about the fact that sports are held without spectators in the stands. I really want a massive coverage of the population with a vaccine.View attachment 67153
ISRO to launch first crewless Gaganyaan flight by end of 2021
The first crewless Gaganyaan Flight which was earlier pushed to be launched in the first half of 2021 due to the COVID-19 pandemic, will now be launched only by the end of 2021.
The crewless flight which is a part of ISRO’s ambitious Gaganyaan Project was originally planned to be launched in 2020 but was postponed due to the ongoing pandemic.
Indian Space Research Organisation (ISRO) will also eventually launch a second crewless flight in 2022 before launching humans to space. K Sivan, ISRO Chairman has informed that the process of human rating has been progressing well and is expected to be complete in the second half of 2021.
Crewless Gaganyaan Flight:
As part of the unmanned Gaganyaan Flight, ISRO has planned on sending a humanoid which has been developed indigenously.
In June 2020 once it became clear that the first crewless flight will not be launched this year, ISRO Chief stated that whether two unmanned missions will be launched in 2021 will depend on the emerging situation and the decision will be taken based on what happens in the coming months. In case, the effects of Coronavirus continue, the space agency may have to revisit some of the plans.
Human Rated S200 motor case launched:
In November 2020, ISRO also flagged off the first human-rated S200 motor case for the first crewless mission of Gaganyaan. According to ISRO, the high thrust solid propellant strap-on boosters- S200 motor case-will be playing a significant role in human-rated GSLV Mkll. Many new design features, in order to human rate the booster, have been introduced in the hardware.
ISRO Chairman informed that the first critical booster segment of the motor case with a length of 8.5 meter, a diameter of 3.2 meter, and weighing 5.5 tonnes has been indigenously developed and delivered by L&T.
K Sivan described it as a major achievement and stated that the next step will be to achieve a human rating of all the hardware that is required for the Gaganyaan mission.
The heavy-lift launcher of ISRO, GSLV Mkll has been identified for the Gaganyaan Mission and is in the process of being human-rated. Reflecting the collaboration by private players, the human rating of the S200 motor case is another successful story of industry collaboration with ISRO.
