Isro plans new propulsion for deep space missions

Indian Space Research Organisation (Isro) is exploring the possibility of developing a new propulsion technology to fuel spacecraft for its future deep space missions.



ISRO is in the process of developing 100W Radioisotope Thermoelectric Generator (RTEG) without radio isotope.’ Isro calls it alpha source thermoelectric propulsion technology.

RTEG will have less mass than solar cells of equivalent power and allow more compact spacecraft that can navigate easier in space. Many missions of Nasa and Russia, Besides China’s 2013 Chang’e 3 mission to the moon and its rover Yutu had used RTG.

It will be useful for long duration missions where alternative energy is not available. the development of RTEG is taken up as it is envisaged that it will be a part of Isro’s deep space missions for power generation and thermal management. the system will be capable of operating in vaccum conditions of deep space, dusty, carbon dioxide-rich and corrosive environments. Isro says the RTG’s weight should be 20 kgs or less, with a life span of 20 years or more and survive indefinitely without damage when stored in the atmosphere at temperatures as high as 50 degrees Celsius.

The system should be safe for human handling in close vicinity under all conditions even with nuclear fuel concealed inside … the unit should be resilient to any pre-launch or post-launch explosion so as to not cause any nuclear contamination in the environment. that means ISRO also working in Nuclear propulsion .



After another Mars mission, Isro could be eyeing Jupiter, Saturn, Neptune and Uranus.

RTG is good for unmanned missions. But we need to start working on Fusion Drives for the long term. They will come up by 2050. The work needs to start now.

For the first time in over five decades of India’s space programme, Isro opened up its facilities to the private sector with two satellites from companies and one from academia being tested in the UR Rao Satellite Centre.

Over the next few months, two private firms will test their engines at Sriharikota spaceport and Thiruvananthapuram rocket centre. Isro will soon give its satellite images to a private firm that offers mapping services.

Sources in URSC said satellites from Tamil Nadu-based Space Kidz India and Bengaluru-based Syzygy Space Technologies have undergone testing.

Isro chairman K Sivan told TOI: “In both cases, we found problems with solar panels and our team is helping them fix them. URSC also tested UNITYsat, which had problems with the separation system which we’re setting right.”

26 proposals under review

UNITYsat is a combination of three satellites designed and built by Jeppiaar Institute of Technology, Sriperumbudur, GH Raisoni College of Engineering, Nagpur and Sri Shakthi Institute of Engineering and Technology, Coimbatore.

Chennai-based Agnikul Cosmos will be allowed to test its engine at Thiruvananthapuram while Hyderabad-based Skyroot Aerospace’s engine will be tested at Sriharikota, Sivan said.

Also, we MapmyIndia, which builds digital maps and offers GIS services, has approached Isro for high-resolution images. These developments are in line with opening up the space sector to private firms. At least 26 proposals, including those from US-based Amazon Web Services and Bharti Group backed UKbased OneWeb, are being reviewed by Indian National Space Promotion and Authorisation Centre.

//////////////////


Two satellites by Indian startups—SpaceKidz India and Pixxel (incorporated as Sygyzy)—were tested at the UR Rao Satellite Centre of the Indian Space Research Organisation (Isro) in Bengaluru. This is a first for the space agency, which so far has only taken help in manufacturing and fabrication of various parts of satellites and rockets from the Indian industry. Isro helped these two companies fix problems with the solar panels on their respective satellites.

Confirming the development, Isro spokesperson Vivek Singh told HT that the two firms have finished the testing already. In the coming months, these two firms will also test their engines at Sriharikota spaceport and Thiruvananthapuram rocket centre.

“There have been several firms that have worked with ISRO in the past, but these firms are into manufacturing satellites. They are almost through with their development. In our next PSLV launch, they could be our co-passengers,” he said.

Earlier Isro had only provided launch facilities to private firms at a cost. In June 2020, Isro chairman K Sivan had announced that the agency will open its labs, testing facilities and quality facilities to private companies so they don’t have to invest in infrastructure. An independent body, Indian National Space Promotion and Authorisation Centre (IN-SPACe), was set up to not only to oversee the space activity of the private sector, but also to handhold and share Isro facilities. The decision of the body would be binding on Isro as well.

Just eight months after this announcement was made, Isro is ready to launch commercial satellites in a PSLV mission scheduled for later this month. It will be the first mission wherein satellites by the Indian industry will be commercially launched by Isro.

A satellite designed by students from SpaceKidz India had been launched by Isro as an experiment in January 2019 using the fourth stage of the PSLV—which usually goes to waste—as the platform for the KalamSat.

The PSLV C-51 mission will carry a Brazilian satellite Amazonia-1 under a commercial arrangement made by the NewSpace India limited, the commercial arm of Isro. In addition, the launch vehicle will carry 20 passenger satellites—including one nanosatellite by Isro, the two satellites under testing, and UnitySat, a combination of three satellites designed and built by Jeppiaar Institute of Technology, Sriperumbudur, GH Raisoni College of Engineering, Nagpur and Sri Shakthi Institute of Engineering and Technology, Coimbatore.

Another startup Skyroot is working towards developing a launch vehicle that is likely to be launched by the end of the year. Isro will share their spaceports—the existing one at Sriharikota and the upcoming one in Thoothukudi—with industries for such missions

Indian Space Research Organisation and location and navigation technology solutions provider MapmyIndia announced an initiative to partner together to offer India’s best, and fully indigenous, mapping portal and geospatial services.

It combines the power of MapmyIndia’s digital maps and technologies with ISRO’s catalogue of satellite imagery and earth observation data, according to MapmyIndia’s CEO and Excutive Director, Rohan Verma.

He termed it a path-breaking milestone in India’s journey towards ‘Aatmanirbhar Bharat’, wherein Indian users would not be dependent on foreign organisations for maps, navigation and geospatial services, and leverage made-in-India solutions instead. “You don’t need Goo*le Maps/Earth any longer”, Verma said in the headline in an article on LinkedIn.

According to ISRO, the Department of Space (DoS) — ISRO comes under it — has joined hands with MapmyIndia to combine their geospatial expertise and build holistic solutions by leveraging their geoportals. DoS entered into an MoU with geospatial technology company CE Info Systems Pvt Ltd, which owns MapmyIndia, on Thursday.

Under the partnership, the combined geospatial expertise of the DoS and CE Info Systems would be leveraged through their respective Geoportals, according to Bengaluru-headquartered ISRO.

The collaboration will enable them to jointly identify and build holistic geospatial solutions utilising the earth observation datasets, ‘NavIC’, Web Services and APIs (application programming interface) available in MapmyIndia, ‘Bhuvan’, ‘VEDAS’ and ‘MOSDAC’ geoportals, the space agency said in a statement.

Indian Regional Navigation Satellite System (IRNSS) called NavIC (Navigation with Indian Constellation, is India’s own navigation system, developed by ISRO. Bhuvan is the national geo-portal developed and hosted by ISRO comprising geospatial data, services and tools for analysis.

VEDAS (VisualisationofEarthobservationDataandArchivalSystem) is an online geoprocessing platform using optical, microwave, thermal and hyperspectral EO data covering applications particularly meant for academia, research and problem solving, according to ISRO.

MOSDAC (Meteorological and Oceanographic Satellite Data Archival Centre)is a data repository for all the meteorological missions of ISRO and deals with weather related information, oceanography and tropical water cycles. Verma said there are many reasons why Indians are better off with an indigenous solution for maps and geospatial services.

“MapmyIndia, being a responsible, local, Indian company, ensures that its maps reflect the true sovereignty of the country, depicting Indias borders as per Government of India, and hosts its maps in India,” he said.

Through the combined partnership with ISRO, MapmyIndias end user maps, apps and services will now integrate with ISROs huge catalogue of satellite imagery and earth observation data, a MapmyIndia statement said.

It would be a much better, more detailed and comprehensive, as well as privacy-centric, hyper local and indigenous mapping solution for Indians, compared to foreign map apps and solutions, it said. Verma said foreign mapping solutions come with a lot of hidden costs.

For example, foreign search engines and companies claim to offer “free” maps, but in reality they make money by targeting the same users with advertising based on invading user privacy and auctioning those users private location and movement data,” he claimed. “This should be very alarming to all citizens”.

“On the other hand, MapmyIndia has an ethical point of view against advertising led business models of such companies, and hence, does not have an advertising business model.By using MapmyIndia maps and applications instead of the foreign map apps, users can better protect their privacy,” he said.

The “sustainable and direct, clean business model” ensures that MapmyIndias maps and apps can be kept free of cost as well as free of ads for users, according to him.

“MapmyIndias maps cover all 7.5 lakh villages, 7500+ cities at street and building-level, connected by all 63 lakh kilometres of road network pan India and within cities, in total providing maps for an unparalleled 3+ crore places across India,” the company statement said.

India plans sustained human presence in space: What’s more in store

Move over Gaganyaan, India is planning to have a sustained human presence in space. The Department of Space has envisaged a national effort to meet the goal of successful demonstration of human spaceflight capability and to achieve the vision of sustained human presence in space. Union Minister Jitendra Singh had said that India’s maiden human spaceflight module ‘Gaganyaan’ will be launched after the second unmanned mission planned in 2022-23.

More in store

The Department of Space has put up for public consultation on the website of the Indian Space Research Organisation (ISRO), the draft “Humans in Space Policy for India — 2021” and guidelines and procedures for its implementation. DoS believes that given the collaborative nature of human spaceflight due to its multi-disciplinary nature, it is essential to have a policy-framework, which not only fosters partnerships but also addresses proliferation concerns and compliance to existing policies, laws and treaties.

According to the draft, human-spaceflight programme needs to be sustained over longer periods to deliver tangible benefits. Hence, it is essential that the policy enables sustained presence in low earth orbit and beyond through reliable, robust, safe and affordable means by undertaking appropriate capacity building measures like collaborations, infrastructure development, facilities modernisation, technology development and human resource development. This would also encourage new industries, create high technology jobs, enable socio-economic growth and further enhance India’s stature and role in space.

“The Humans in Space Policy aims for sustained human presence in space as an instrument for development, innovation and foster collaborations in alignment with national interests,” the draft read.

Various technological elements such as development of human rated launch vehicle, environmental control and life support system, crew escape system, deceleration system, crew selection and training, crew recovery operations, development of human centric products, and micro gravity experiments shall be undertaken by department utilising expertise of ISRO, national research institutions, academia, industry and other organisations.

As part of demonstration of human space flight capability, department shall

undertake developmental unmanned missions prior to manned mission. A standardised approach towards safety and reliability shall be adopted for

mission assurance and success

Indian human space program envisages undertaking the demonstration of human spaceflight to LEO in the short-term and will lay the foundation for a sustained Indian human space exploration programme in the long run. DoS with mandate to carry out space activities in India shall define a roadmap with regard to human space activities.

In order to pursue the objectives as stipulated in Humans in space policy, the necessary technology and gap areas shall be identified. The thrust areas thus identified shall become part of technology roadmap of ISRO. The thrust areas will include key technology elements e.g. Regenerative life support systems, development of Rendezvous and docking systems, Inflatable habitats, extravehicular activity suits etc.

Indian human space programme involves various national institutions, organisations and stakeholders. A suitable mechanism shall be constituted to ensure effective coordination and seamless execution among various agencies involved. Announcement of opportunities shall be floated for encouraging the participation of national research institutes/academia/industries.

They couldn't spend even 50% of last year's budget due to corona. Priorities of this year are pulling off human spaceflight and launching more satellites for communication window. Rest is postponed.

Yeah this is the problem, i am not taking about corona. But world space agencies are working, at one time ISRO talks about 12 launches/year or more then that, that also impacted. Somewhere down the line ISRO looses the track. Look at DRDO , i think first time they test so many things in corona time.

"World Space agencies" (Out of 6 actual space programmes) except strictly NASA and to some extent CNSA both of which keep lot of rocket modules in spare, have highest aerospace productions, and launch very small launchers many times, all other space programs have their furnaces cool for a while.

Gaganyaan manned mission not before 2023: Minister


The Gaganyaan manned mission, hit by the pandemic-triggered restrictions, has been further delayed and India’s maiden human spaceflight launch is not likely before 2023. “First unmanned mission is planned in December 2021.

Second unmanned flight is planned in 2022-23, followed by human spaceflight demonstration,” Union minister of state for space Jitendra Singh told the Lok Sabha in a written reply recently. Isro chairman K Sivan told TOI that a “human-rated GSLV MkIII rocket with a modified top portion involving provision for a crew module and a crew escape system is being readied for the first unmanned mission in December and a humanoid to be sent on it will be ready by October”.

The minister also informed Lok Sabha that additional Rs 900 crore was allocated to Isro for financial year 2020-21 for developing capacity and launching satellites. On foreign satellites launched by India, Singh stated that the total number of satellites launched till date is 328 from 33 countries and the revenue earned is “25 million dollars and 189 million euros”.
On Covid restrictions stalling the programme, the minister said in the replythat the astronaut training in Russia was halted over a month “for a period from 28th March, 2020 to 11th May, 2020” and the training “henceforth resumed since 12th May, 2020”.

“Isro is striving towards achieving Atmanirbharta in the field of capacity development in launching satellites; therefore, no policy is envisaged for seeking foreign cooperation in this direction,” a Department of Space statement said.

The Gaganyaan mission will not be India’s solitary space mission as Isro, for a sustained human presence in space, is coming out with a policy framework and a long-term roadmap. The agency has sought suggestions on its “Draft Humans in Space Policy for India, 2021” by February 28. Sivan said suggestions on the draft will be reviewed by March and a concrete shape to the policy will be given thereafter. “Thereafter, we will work on human space exploration, launch vehicle, national space policies and finally the Space Act,” he said.

About another big project, the Isro chairman told TOI that the agency is planning to switch over to the electric propulsion (EP) system in satellites and will soon have all geo satellites loaded with this technology for space manoeuvring.

“We will launch a technology demonstrator satellite somewhere in October-December to test three technologies — our own EP system, indigenous atomic clock and travelling wave tube amplifier, a key component for communication satellites. Currently, nearly 50% mass of a satellite comprises chemical fuel. Once the EP is used, it will occupy less space and bigger satellites can be launched,” Sivan said, adding “we are also planning for dual EP and a mini chemical propulsion system for a better thrust with less mass”.

On missions scheduled this year, Sivan said, “Besides the unmanned Gaganyaan mission, we are targeting to launch the first demonstration test-flight of a Small Satellite Launch Vehicle (mini-PSLV), two advanced geo satellites, one remote sensing satellite and an upgraded Oceansat this year.”

Check out the Valles Marineris Co. from Bengaluru. They are making the simulators for the Gaganyaan mission, and they have also made simulators for Soyuz missions, and Soyuz upgrades. Top co. on planet for simulators. We need complete independence in Space sector. The Space bills passed in Sept. 2020 were monumental.

Wow , so India already has a connection with ISS. World should know about this ! India never does PR of its achievements.

Recently , if u look at UAE mars mission site. Not a very good one from technical stand point but yeah site looks very pleasant.

I try to find out Gaganyaan connection on Valles site, i not able to found. Please share if anybody have ?

Space PSU NSIL to launch satellite for TataSky

India’s first and only Space Public Sector Unit (SPSU), New Space India Limited (NSIL), has finally taken wings and will be launching a communication satellite dedicated to augment direct-to-home (DTH) services in the second half of this year using a foreign launch service.
To do this, NSIL, which was established under the Department of Space (DoS) as part of India’s reforms to liberalise the space sector, has got Rs 700 crore equity from the government.

K Sivan, secretary, DoS, told TOI: “This money will eventually be paid back. As part of the reforms, the role of NSIL now is to also own and sell assets and the first satellite it will acquire is GSAT-24 which will be launched to cater to TataSky’s DTH business. So far, Isro owned all the satellites and its services were sold through Isro’s own entity (Antrix). This (NSIL) will usher in a new era in India’s commercial space activity.”

GSAT-24 will be a 4.1 tonne communication satellite that will put into space 24 Ku-band transponders to be used for DTH services. “The satellite’s cost is Rs 400 crore and NSIL will be launching it through Arianespace. The launch is expected to happen sometime in September,” Sivan said.

The PSU is also negotiating to acquire GSAT-20, a high-throughput satellite, which will also be launched commercially. “Aside from GSAT-20, DishTV has held preliminary talks with NSIL for another satellite,” Sivan added.
“When NSIL was formed, the mandate was different. Now, with

Atmanirbhar Bharat and the space reforms, it has completely changed. We are now expected to carry out a lot of capital intensive projects to enable a demand-driven ecosystem. There are a lot of developments, we are in the process of finalising the deal for two satellites with DoS,” G Narayanan, CMD, NSIL, said.

Buying From Startups
Further, Sivan said that while the first few satellites are being acquired from Isro, NSIL, in the future will also be buying from the private sector, including startups.

Narayanan said: “We are not restricting our sources to fulfil our requirements to any government organisation. We will be open and whoever has the strength and capability, we will be sourcing it from them on a commercial basis.”

While NSIL’s first commercial project will be the PSLV launch scheduled for later this month, the PSU’s role there was limited to connecting the foreign customer — Amazonia-1 from Brazil — with Isro.

“In the PSLV launch, Isro is providing the service and the Brazilians came through an NSIL contract. But GSAT-24 and 20 that we are talking about will be completely NSIL’s. Isro will only be a vendor, and the satellite will be owned by NSIL, this is a new era,” Sivan said.

Not really. Here is the history figures from 2017 to 2020 of orbital launches of 6 major agencis:

1613952475875.png


There were only 3 reduced their launches in 2020: Europe, Russia and India:
Europe has been steadily decrease their launches number from 2017. Comparing to 2019, they only reduced 1 (6 vs 5), so hardly impacted by Covid-19;
Russia was the one reduced most (-8), but in the launch schedule, they only missed Jan, Jun and Nov, the impact was more likely caused by the funding issues instead of Covid-19;
India was another one sharply decreased (6 -> 2). And they missed the whole period from Jan to Oct. The only two was in Nov and Dec. So, yes, India is the one being hit most.

Yes, really. They should give some explanation for the extended delay. No one is asking for classified or sensitive information. Just a general technical and/or financial reason. Covid would be one, of course.
But this SSLV would be axing your own feet considering 3 Private companies working on this domain of SSLVs, hence I feell it should be limited to government use as we need private sector involvement more...
