Now they can outsource smaller launches to pvt firms.
Incidentally our SSLV's first developmental trails must be in July/August.

New Space Agency!!
State-owned NewSpace creates a flutter among space startups

No clarity yet on functioning of the new business arm of DoS

In early March, the small set of NewSpace entities in the country sat up in disbelief to see a state-run company taking birth in that name although it did not fit the standard definition of their league.

On March 6, the Department of Space (DoS) quietly registered its second commercial entity, NewSpace India Ltd. (NSIL), in Bengaluru.

At the time, the small, new age ventures and startups foraying into the space industry were still coming to terms with the news of February 19 that the Union Cabinet had cleared a new business arm for DoS.

Surprise, because DoS already has a commercial venture, Antrix Corporation Limited, which was set up in September 1992 to market the products and services of the Indian Space Research Organisation (ISRO).

While the government hasn’t said much about NSIL plans since the first announcement, officials in the DoS and ISRO have been trying to figure out how exactly Antrix and NSIL would operate their respective businesses in the common, niche area.

What we do know is that NSIL has an authorised capital of ₹10 crore and a paid up capital of ₹1 crore. And that two senior officials of Antrix — Executive Director D.R. Suma and Director (launch services) D. Radhakrishnan — were moved to NewSpace in March to help the new venture get off the ground.

Board soon

Two senior ISRO officials, speaking on condition of anonymity, said it was still early to talk about the new company. “Currently the department [DoS] is completing statutory formalities such as the formation of a board of 8-10 directors,” one of the officials said. “We would like to do it as quickly as possible. A selection committee will find the Chairman and Managing Director,” the official added.

“Both the companies are there [now]. Their roles and responsibilities will be divided. The new company will basically focus on industry participation. Clarity will emerge as we go forward,” the official observed.

Haze ahead

NewSpace India enters the scene at a time when globally and in India small, low-budget new age ventures, many helmed by young dreamers inspired by entrepreneur Elon Musk's Space Exploration (SpaceX), are vying to turn 21st-century space fantasies into reality.

The new company does have mandates: transfer technology to industry for producing the commercially successful PSLV spacecraft launchers; outsource assembly of small satellites and the upcoming Small Satellite Launch Vehicle (SSLV). It would also be tasked to “commercially exploit the R&D work done by ISRO centres and DoS constituents”.

“A lot of new [business] activities are cropping up, such as customer satellites, spinoff technologies, industry participation, production partners, ground stations, and satellite data sales,” the official said.

Some serving and former DoS associates apprehend that NSIL may one day cannibalise Antrix and reduce it to an idle shell. They contend that the government may have created NSIL just to erase an eight-year-old blot and resultant liabilities associated with Antrix’s cancelled Devas contract. The ISRO official, however, ruled out any such eventuality, asserting that Antrix’s expertise, accumulated over decades, could not be recreated or transferred overnight. “Whatever Antrix has been doing it will continue to do. It has been doing well in [getting contracts for] commercial launches and will continue it.”

May be for SSLV like operations.

Doesn't the space bill need to pass before these guys can do anything?

Yes, lot of startups in India are emerging that could be our equivalent of SpaceX, Blue Origin & OneSpace.
This bill needs to get passed ASAP.

Launch frequency will cross 30 and dozens of launchers and new technologies will surface rapidly. Our list of orbital launch systems could be very long & diverse.

Which Way to Space……….. Will Indian NewSpace Make for India?

Space 2.0 India – Creating a $10 billion space economy that supports 100,000 high-skilled jobs
So basically, NSIL is meant to transfer government's tech to private startups.

2 GB storage is too low IMHO.
The mission life is mentioned as 1 Lunar day. I think that is just to keep our expectations low.

2gb is more than enough for scientific data which is mostly numbers and text.
As for images rover will constantly upload them to orbiting chandrayan so on-board storage will probably be only used as temporary buffer for images.

PSLV-C46 mission on 22nd May 2019 from Satish Dhawan Space Centre SHAR

PSLV-C46 which is the 48th mission of PSLV, will launch RISAT-2B, a Radar imaging earth observation satellite, from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch is tentatively scheduled at 0527 hrs IST on May 22, 2019, subject to weather conditions.

PSLV-C46 is the 14th flight of PSLV in 'core-alone' configuration (without the use of solid strap-on motors). This will be the 72nd launch vehicle mission from SDSC SHAR, Sriharikota and 36th launch from the First Launch pad.

RISAT-2B will be placed into an orbit of 555 km at an inclination of 37 degree.

As done in PSLV-C45 launch, ISRO has also made provision for public to view the launch from recently opened Viewer’s gallery at Satish Dhawan Space Centre SHAR, Sriharikota. Online registration for the same will start 5 days before the launch.

Going by the Department of Space (DoS) ’s stated position on 5G services, India’s nascent efforts to develop a desi Global Positioning System (GPS) may be derailed.

The DoS seems to have failed to take into account the interference in the earth stations — which manage the Navic satellite — by India’s neighbours on all the four sides, once they roll out their 5G services.

In its presentation to the wireless planning and coordination cell (WPC) of the department of telecommunications, the DoS has taken care to seek reservation of 25 Mhz of spectrum in the 3.5 GHz band (3.400 to 3.425 GHz), which is a 5G band, so that mobile signals do not interfere with the satellite signals.

However, it seems to have forgotten that neigbouring countries, be it Pakistan, China, Myanmar, Bangladesh, Bhutan, Nepal, or Sri Lanka will operate their 5G services in the same band thus affecting the signals.

The story is something like this: India has already launched its Navic satellite, an initiative to develop an indigenous version of GPS and important from a defence perspective. Though the satellite has been launched the services are yet to start. The earth stations for managing the synchronisation of clock signals from the satellite system have been located at places like Hassan, Bhopal, Jodhpur, and Shillong. To prevent any interference from the 5G mobile/BTS signals in these four earthstations, the DoS has written to the WPC asking that 25 Mhz of spectrum (3.400 to 3.425 GHz) in the 3.5 GHz band of 5G band be reserved for it.

Mobile operators, however, are of the view that this large chunk of spectrum need not be reserved for DoS on an-India level. They say even a small protection zone of 25 KM radius, anchored around the satellite earth stations, is sufficient to prevent the 5G systems from interfering with the satellite signals. The DoS has vetoed this suggestion saying it needs an isolation zone of 1400 KM radius to ensure an interference-free operation. This implies that the presence of any 5G system within this radius of the satellite earth stations will impact reliable functioning.

However,while this would mean that no operator would get a contiguous chunk of airwaves at the 5G spectrum auctions, this isn’t that big a problem. The problem will arise from neighbouring countries like Pakistan, China, Myanmar, Bhutan, Bangladesh, Nepal, and Sri Lanka, all of which fall within the 1,400 KM radius of the locations where the earth stations have been set up. All these countries will sooner or later launch 5G services in the 3.5 GHz band and they are under no obligation to fall in line with DoS’s demand of respecting the 1400 KM protection zone. In such a scenario the desi GPS system will be vulnerable to interference from the mobile networks in neighbouring countries, impacting the very efficacy and security of the system.

BREAKING: Gaganyaan project may fail.


After doing research on this subject I have concluded that Gaganyaan mission can't take place in 2022.

• No human rated launch pad. If (a big if) they start building next year it will take 3 to 4 years.

• No progress in HLS system eg. O2 recycler, CO2 scrubbers, human support system etc. It will take many years to make and validate the same.

• No progress in subsystems development either.

• No validation of spacesuit in high altitude flights.

• No final selection process for astronauts even in 2019. Just 3 years before supposed mission.

• No training facilities for astronauts

• No roadmap for LV testing.

A realistic timeline for ISRO's human spaceflight would be post 2030. Maybe 2035-2040 period at earliest. This too is impossible because...

• After 2022's timeline failure would put project in cold storage. People will see ISRO as a failed organization, Big humiliation on international level. Political funding will stop and the project will die slow death.

• To win people's confidence back ISRO may ink contract with SPACE-X or Roscosmos for a token space mission from abroad.

Conclusion: India may never send humans in space on their own for foreseeable future.

Very sad if true.

I wish we could also be a space power one day.

If this is the case then they are more knowledgeable to know if things will go haywire. What you've laid down are just few variables, however there are thousands of not millions.

Let's just hope the systems are simulated to almost every possible scenario.

I like the spaceX strategy, they have more of a rapid prototyping and rapid testing strategy, but then it's further into stages. It goes without a doubt that a huge budget gives them a slight advantage.

Third launch pad was to be made but no movement till now. Test of human rated GSLV mk3 no where in sight. People busy with chandrayaan 2 i think. Very unlikely gaganyaan would be before 2025. Maybe delayed but will definitely happen in future.
