‘India’s first solar mission likely to launch next year’: ISRO.

India’s first solar mission, which was pushed from early 2020 due to the Covid-19 pandemic, is likely to be launched in the third quarter of 2022, when the country’s second space observatory Xposat, aimed at helping astronomers study cosmic sources such as pulsars and supernova, will also be launched, senior officials from the Indian Space Research Organisation (ISRO) said.

Talking about the purely scientific missions at a conference this week, director of human spaceflight centre, Dr Unnikrishnan Nair, said, “The solar mission Aditya L1 will be launched in the third quarter of next year (2022) and will provide more insights into the origin of the universe and many other unknowns.”

The spacecraft in the Aditya L1 mission will be sent 1.5 million km away from the Earth to L1 Lagrangian, a point between the Earth and the Sun where the gravitational pull of both the bodies on the satellite is equal to the centripetal force needed to keep the satellite in orbit. It is like a parking area in space and is great for observing several phenomena without hindrances from eclipses.

Xposat will be the other purely scientific mission that the space agency will undertake next year. It will be launched aboard a small satellite launch vehicle, which is currently in the development phase. The new launch vehicle is likely to have its first development flight by December this year. ISRO qualifies a launch vehicle to be mission-ready after two successful development flights.

“Xposat will allow us to study the polarisation of celestial events. It will be launched by an SSLV which is under development. The first development flight will be by the end of this year. Academicians are looking forward to the data generated from this mission,” said Nair.

The SSLV, which is being developed for the commercial launch of small satellites, costs only ₹30 crore as compared to ₹120 crore for a polar satellite launch vehicle (PSLV). The SSLV can be assembled by a team of six scientists within seven days in comparison to a team of 600 that takes a couple of months to assemble a PSLV.

The Covid-19 pandemic severely affected the number of launches ISRO could undertake in 2020 and 2021. There has been a total of just four launches in the two years, of which, one was a purely commercial launch with the main payload being an earth observation satellite from Brazil called Amazonia-1.

Before the pandemic, the space agency had planned for 20 launches in the financial year 2020-21, including the first unmanned flight under the Gaganyaan mission. The Gaganyaan mission is also likely to be undertaken by the end of 2022 or in early 2023.

Indian industry to produce two more entire rockets - GSLV-Mk III and SSLV.

The Department of Space (DoS) plans to realise entirely-built rockets -- GSLV-Mk III and SSLV -- from Indian industry partners, in addition to PSLV, according to a top official of its commercial arm NSIL.

NSIL (NewSpace India Limited) has received three bids -- HAL-L&T, BEL-Adani-BEML, and BHEL, in response to the request for proposal (RFP) floated by it for end-to-end production of PSLV (Polar Satellite Launch Vehicle).

"We are now going through the techno-commercial evaluation (in respect of the three bids)", NSIL Chairman and Managing Director, Radhakrishnan D, told PTI here.

He said the process will be completed within the next two months with one of the bidders bagging the contract. The selected bidder will be responsible for realisation of five numbers of PSLV.

Immediately after selection of the bidder to produce the entire PSLV, NSIL will release Expression of Interest (EOI) for end-to-end production of another operational rocket -- GSLV-Mk III (Geosynchronous Satellite Launch Vehicle) -- in a similar fashion, Radhakrishnan said.

"I am targeting before the end of this year (to release EOI for GSLV-Mk III)", he said.

NSIL also has plans to realise SSLV (Small Satellite Launch Vehicle), being developed by the Indian Space Research Organisation (SSLV) with the first development flight expected by this year-end, through Indian industry partners.

"We are waiting for the first mission (of SSLV) to happen successfully", Radhakrishnan said. "This (SSLV) will be an ideal candidate for industry production".

SSLV is a three-stage all solid vehicle and has a capability to launch up to 500 kg satellite mass into 500 km low earth orbit (LEO) and 300 kg to Sun Synchronous Orbit (SSO).

The new generation compact rocket has been designed to meet "launch on demand" requirements in a cost-effective manner for small satellites in a dedicated and rideshare mode, according to officials of Bengaluru-headquartered ISRO.

Industrialisation of space activities is gaining momentum in India.

About 40 space startups and industries are in consultation with ISRO for support related to various domains of space activity such as development of satellites, launch vehicles, develop applications and provide space-based services.

India's Foreign Direct Investment policy in the space sector is also getting revised which, the ISRO Chairman and DoS Secretary K Sivan believe, will open up huge avenues for foreign companies to invest in the country.

Earlier this month, the DoS entered into a Framework MoU with two spacetech startups -- Skyroot Aerospace and Agnikul Cosmos -- for access to ISRO facilities and expertise towards the development and testing of subsystems/systems of space launch vehicles.

Isro lines up 3 Earth Observation Satellites with key indigenous technologies.

The Indian Space Research Organisation (Isro), which has had a negligible year so far as launch missions go, is hoping to launch three Earth
Observation Satellites (EOSs) in the last quarter of 2021.

While two of them — EOS-4 (Risat-1A) and EOS-6 (Oceansat-3) — will be launched using Isro’s workhorse PSLV, the third one, EOS-2 (Microsat), will
be launched in the first developmental flight of the Small Satellite Launch Vehicle (SSLV), marking the beginning of a new class of launch vehicles in India.

Isro has completed SSLV Payload Fairing (SPLF) functional qualification test successfully and other testing activities are in progress. EOS-4 was to
be originally launched in September, sources in Isro said, adding that the review committee had not cleared the satellite, which postponed the launch.

Isro chairman K Sivan told TOI: “The plan is to achieve those launches by the end of this year, but since some key indigenous systems like TR module, TWTA and circulators as part of our endeavour to reduce imports, we will be carrying out extensive tests to find if there are any technical issues. This may take some time.”

TR modules refer to transmit and receive modules that help in telemetry and tracking of the satellites, while TWTA (Traveling Wave Tube Amplifiers) are commonly used in satellite communication links, earth observation payloads, scientific missions or probes, inter-spacecraft communications links etc.

As reported by TOI in March, Isro has been looking at indigenising various technologies aimed at reducing imports.

New Model
Further, Sivan said that the launch of EOS-4 would also mark the beginning of a new model for Isro as intended by the space reforms initiated by the Centre.

“...Earlier, we had a supply driven model. After Isro made a satellite, we offered it to ministries and government agencies. Now, even Isro is looking at a demand-driven model. From the next satellite, we will be doing this,” he said.

The three satellites that the space agency is planning to launch are meant for ministries like agriculture, home affairs, earth sciences and environment and forests.

Unlike communication satellites where the entire capacity could be demanded by one customer, a single Earth observation satellite can simultaneously cater to multiple customers as the data generated by these satellites can be analysed for different uses

Somewhat encouraging news. The SSLV had a problem with its first stage ignition. Perhaps that issue has been solved? I think it's realistic to expect only one launch by year-end, the PSLV with RISAT-1A. The other two will probably pushed to the new year. Would love to be wrong!

Bharti Enterprises-backed OneWeb to launch sats on GSLV-Mk3 & PSLV
BENGALURU: UK-based global firm OneWeb, which already has 322 satellites in orbit, will be using Isro’s most powerful launch vehicle — the GSLV-Mk3 — and the space agency’s workhorse, the PSLV to launch satellites from Indian soil.
Sunil Bharti Mittal, chairman, Bharti Enterprises, the largest stakeholder of OneWeb, said on Monday: “The collaboration with Isro is moving along and I am happy to announce that we have made arrangements to use Isro’s workhorse PSLV and importantly the new rocket with a very large payload capacity, the GSLV-Mk3, to launch OneWeb satellites from the Indian soil.”
He said OneWeb will be the first customers to start bringing in commercial positions in the Indian space market and will pave the way for more international customers to come to India.
“OneWeb will deliver connectivity to every square inch of the country, and will be providing its services in India by the middle of next year,” Mittal added.

In a separate development, space PSU NewSpace India Limited (NSIL), which has been mandated with productionising launch vehicles, is also looking to issue an expression of interest (EoI) for GSLV-Mk3, enabling private players to build the rocket.
NSIL is at present in the process of evaluating bids for bids submitted by industry players — one by a consortium of HAL and L&T, the second by a consortium comprising Adani-Alpha Design, BEL and BEML and the third by BHEL as a single firm.
NSIL CMD Radhakrishnan D told TOI: “Once the process involving PSLV is completed, we will issue the EoI for GSLV-Mk3. We are specifically looking at Mk-3 and not other GSLV class of launch vehicles.”

I'm sorry but this does not sound remotely realistic.
India has only 2 launch vehicle startups- Agnikul and Skyroot. Another Bellatrix which is focused on satellite propulsion systems. They are located in Hyderabad, Chennai and Bangalore - the aerospace and industrial hubs of India. ( We ourselves are located in Trivandrum ).
Gorakhpur simply does not exist on the aerospace map of India so it makes no sense to start such a company there.
The technical details do not fly- what does thrust vectoring have to do with reusability?
At best this is wildly optimistic, at worst it is some scam to raise money from gullible VCs. This sounds more like Drone boy Pratap and schoolboy selected by NASA type of stories.

ISRO had mentioned the disruption of supplies from MSME sector due to Covid for the slowdown in its activities. Looking at the way all the sectors have picked up this simply does not wash. There is something that is not being disclosed. God forbid but maybe the number of Technicians/Scientists ISRO has lost due to Covid is impacting its operations big time.

According to a YT Defense channel:

Deccan Chronicle has reports that the assembly of PSLV that was supposed to launch an Earth Observation Satellite 'in the third quarter' has been halted after completion of the first stage. There is no reason being given as to why the assembly of the launch vehicle has been stopped and ISRO is not willing to give any official statement regarding this.

If true then something is stinking big time. ISRO has not been the same since events (failure of GSAT-6A) that led to recall of GSAT-11 from Arianespace. Since then there have been setbacks, failures and multiple missed deadlines. Hope if there is anything causing sabotage through defective parts or supply chain issues, then it is taken care of very soon.

The reason given is they wanted instructions to proceed further. And the article says this could be because of the re-organization where the private sector was supposed to be responsible and ISRO launch responsibility shut down (and presumably people either move to the winning private company or lose their jobs, with a small %age re-accommodated elsewhere). Of course, this PSLV would almost certainly not be one of those 5 launches to be contracted for. It's also unlikely that there were systemic failures/quality failures from the GSLV Mk II launch that impact the PSLV. In any case that report also has not been published

Failure of leadership if you ask me.

sabotage


This word is thrown around too loosely.

indias first manned ocean mission samudrayan launched.

India’s first manned ocean mission ‘Samudrayan’ was launched here on Friday by Union Minister Jitendra Singh and with this the nation joined an elite club of nations having such underwater vehicles for carrying out subsea activities.

The nation has made huge progress in science and technology and when an Indian goes up into space as part of the Gaganyaan programme, another would dive deep into the ocean, the Minister said.

The Minister tweeted,”Launched India’s First Manned Ocean Mission #Samudrayan at #Chennai. India joins elite club of select nations USA, Russia, Japan, France & China having such underwater vehicles. A new chapter opens to explore ocean resources for drinking water, clean energy & blue economy.”

In his launch address at the National Institute of Ocean Technology here, Singh said the mission does not only increase the scientific capacity but also gives the nation a sense of esteem that “we are doing something which is no less than any other country of the world.”

“What we are actually contributing is not only confined to the realms of scientific work, it is actually contributing to building of India’s national esteem,” he said at the event that also coincided with the institution’s foundation day celebrations.

“Very soon, may be in a year or two, we have a man going deep into the ocean, and I was telling the other day to some of the scientists from ISRO that it was a strange coincidence because Gaganyaan has got delayed.”

“It was to be launched somewhere by the end of this year or before the next Independence day. I said it was God’s will, now we have one man going up in space and one in the ocean simultaneously. The delay in Gaganyaan has virtually timed it with your deep sea mission. So when an Indian goes up into the space, same time, an Indian will go deep into the ocean. See what a huge progress,” the Minister said.

An official release said the Matsya 6000 under Samudrayan initiative is capable of carrying three human beings in titanium alloy personnel sphere of 2.1 metre diameter enclosed space with an endurance of 12 hours and an additional 96 hours in case of emergency situation.

The niche technology facilitates carrying out deep ocean exploration of non-living resources such as polymetallic manganese nodules, gas hydrates, hydro-thermal sulphides and cobalt crusts, the NIOT said.

Matsya 6000, the deep sea vehicle, will be ready for qualification trials by December 2024, according to an NIOT official.

“The manned submersible can take three scientists to ocean depths to explore oceans and to survey the ocean bed and collect the data and samples,” the official said.

By the end of 2022 or 2023, the shallow water (500 metres) phase is expected to happen which would be followed by more deeper initiatives, he added.

“Indigenous efforts are underway at NIOT towards design of the vehicle and some of the subsystems are realized from Indian as well as from global market towards its special usage in high pressure deep sea environment,” the release said.

The NIOT had developed a ‘personnel sphere’ made of mild steel with local industry for an operational capability of 500 metres and tested for its usage as per the International Classification and Certification Agency for man rated operation during this month sea trial using Ocean Research Vessel Sagar Nidhi in Bay of Bengal.

The deep sea vehicle shall be maneuvered at deep sea floor with six degree freedom using battery powered propulsion system for 4 hours at 6000 metre depth, according to the release.

“Basically this vehicle is a platform to carry any devices, sensors etc to deep sea for doing experiments/observations in the presence of a human being.” This programme shall augment India’s capability with infrastructure facility such as high thickness welding facility and deep ocean simulator.

During the course of the programme new skill sets are being added under the capacity building which would pave the way for industry development within the country under ‘Atmanirbhar Bharat’ in the 75th Year of India’ Independence.

System design, concept of operation, subcomponents functionality and integrity, emergency rescue, failure mode analysis are reviewed and certified as per the rules of International Association of Classification and Certification Society for man-rated usage of manned submersible at a depth of 6000 metres, the release added.

Pixxel is another satellite startup based in bengaluru, kerala.
I think Prada has a YouTube video of the interview with the founder.

Early days but hope govt gives a massive push (infra & money) to establish an ecosystem. Even Thailand has done this for there pvt sector.

This is super true. ISRO reports directly to pmo. There are no bureaucratic layers in between. Vision or change of course has to come from pmo.

I'll add another point regarding the functioning difficulties of ISRO.

The govt has in the last month, clamped down hard on importing items by all govt departments including ISRO. Now it is very much more difficult to import stuff than it was earlier.
Now they are stuck in a bad situation. I don't know what the solution is, hopefully they are working on it. At the very least I hope it comes out in the open that ISRO is far less 'indigenous' than people think it is.

Maybe the pmo is aware of the issue and decided to bite the bullet? This will force isro/industry to be more indigenous. Policilike this can make or break the org

The reason for the GSLV F-10 failure was a 50 millibar reduction in the LH-2 tank pressure,” said Dr V Narayanan, director of Isro’s Liquid Propulsion Systems Centre, during his quality day celebration address at the Vikram Sarabhai Space Centre in Thiruvananthapurams.


So looks like manufacturing issues at play here.
The engine did not ignite due to low pressure in LH2 tank.

Is ISRO working on reusable launch vehicles like SpaceX’s Starship?
A very interesting article on Starship: https://caseyhandmer.wordpress.com/2021 ... nderstood/

Isro working on tech that can beat even Star Trek's
BENGALURU: Isro is on an interstellar overdrive, working on a bunch of future technologies that could be the stuff of Hollywood sci-fi. Think self-eating rockets and self-vanishing satellites, to name just a few among the 46 slices of mind-bending tech taking shape at its innovation hub.
"All our rockets have metal casings that are dropped into the sea after launch or become (final-stage) space debris. We are working on a technology through which rockets will effectively eat themselves, eliminating waste-dropping into seas and space debris. We are looking at special materials for casings that can burn up along with motors," Isro chairman K Sivan told TOI on Tuesday.
In the same vein, self-vanishing satellite technology would enable spacecraft destruction, once its lifetime is over, through a "kill button" to kickstart a process that will burn it up in-orbit.
"When rockets fly, there are defects sometimes. Self-healing materials can correct some of these defects by themselves," Sivan said.
Make-in-space concepts, quantum communication and advanced radars are the other technologies Isro is focusing on as part of the plan to prepare India for future even as private enterprises manage day-to-day launches.

Is this the most rubbish thing I ever heard? No launches, no indigenization. no new technologies but sci-fi ? LOL
Look at the comments for this article, people are wisening up to the nonsense.

^^ Really wish such cring-ey articles wouldn't be published, esp given the dismal almost zero-launch record over the past 2 years by ISRO

Of course, most of the hyperbole is fault of the ToI reporter and not the actual words of the chairman

I am looking forward to K Sivan retiring. Hope it happens soon. His tenure from the start has been nothing but a disaster as far as ISRO's performance is concerned and boy dont even get started with the handy Covid excuse.

Govt approves proposal for GSAT-7C satellite for Air Force

IANS, New Delhi, NOV 23 2021, 21:45 ISTUPDATED: NOV 23 2021, 21:45 IST

The Defence Ministry on Tuesday approved the procurement of GSAT-7C satellite and ground hubs worth Rs 2,236 crore for the Indian Air Force for real-time connectivity of software defined radios.
The complete design, development and launching of satellite will be in India, and it will enhance the ability of Armed Forces to communicate beyond the line of sight, the ministry said.
The decision was taken during Defence Acquisition Council (DAC) meeting held under the chairmanship of Defence Minister Rajnath Singh. During the meeting, it was accorded Acceptance of Necessity (AoN) for one Capital Acquisition proposal of Indian Air Force for its modernisation and operational needs amounting to Rs 2,236 crore under the category of 'Make in India'. The procurement proposal of Air Force was for GSAT-7C satellite and ground hubs for real-time connectivity of software defined radios (SDRs). Induction of GSAT-7C satellite and ground hubs for software defined radios (SDRs) will enhance the ability of Armed Forces to communicate among one another in all circumstances in a secure mode.

WOW

Skyroot tests Semi cryo engine
(Article says cryo, but it is actually semi-cryo)

Hyderabad-based Skyroot Aerospace on Thursday (25 November) announced that it has successfully tested India's first privately built fully cryogenic engine 'Dhawan-1'.

The engine, which has been named in honour of eminent Indian Rocket scientist Dr Satish Dhawan, uses Liquid Natural Gas (more than 90 per cent Methane) and Liquid Oxygen cryogenic propellants, which are high performance, low-cost, and green.

According to the company, this engine has a vacuum thrust of around 1.5 kilonewton (k)N and demonstrates upper stage technology of the firm's orbital vehicle Vikram-2.

He was supposed to retire on 14th jan this year.
But was given one year extension till jan 2022 possibly to oversee Gaganyaan and ChandraYaan3.
He might hang in there till atleast CY3 is launched which could be in Q3 2022.

Criticism mounting on how the details of the cryo failure report is being released. Rather than release the full report or atleast place part of it in public domain, information is released in bits and pieces.
I had posted about this speech 2 weeks back.

https://science.thewire.in/spaceflight/ ... -official/

But thanks to the tradition of ISRO employees sharing important details in obscure speeches and communiqués, it has now come to light that the F10 mission failed specifically because of an anomalous drop in pressure in a tank containing liquefied hydrogen.


Pumps work by creating a pressure differential between two tanks. If the hydrogen tank didn’t have a sufficient amount of pressure, there may not have been enough impetus to cause the liquid hydrogen to flow into the combustion chamber. And without liquid hydrogen, the cryogenic engine wouldn’t have provided thrust, causing the rocket to stop climbing.


Two more months for K Sivan to retire. Maybe the failure report will be released after that.

India, Russia sign pact to deepen space cooperation.

India and Russia on Monday vowed to deepen collaboration in the space sector, including in the human spaceflight programme, and signed an agreement for cooperation in the building as well as operation of launch vehicles.

A joint statement issued after the summit said the two countries welcomed the enhanced cooperation between the Russian State Space Corporation 'Roscosmos' and the Indian Space Research Organisation (ISRO) including in the human spaceflight programmes and satellite navigation.

They agreed to study the prospects of the development of mutually beneficial cooperation in the development of launch vehicles and the use of outer space for peaceful purposes, including planetary exploration.

To facilitate further cooperation in Space, the two countries signed an agreement on technology protection due to cooperation in the field of research and use of outer space for peaceful purposes and building and operation of launch vehicles and ground-based space infrastructure
