Anyways we need to look into future. I think ISRO should be more aggressive now (look into new areas in space) and take less project, but complete on time.

Russia isn't much different either. At least in sectors I have worked in. Russians sell equipment and at best let us assemble. Even US is more generous in transferring technology once committed unlike Russia who backs off. The image lies in Indian PSUs for a reason.
Most of our imported tech from France.

ISRO's existing geospatial infrastructure which created world's largest fleet of remote sensing satellites by India, came into existence thanks American MNCs worked in India as vendors and created even more. Not any civilian domain of Indian space program was touched. In fact before testing Prithvi missiles, we had consultation in launch vehicle tech as well.

Further, cryo deal with Russia was not a technology deal. It was essentially an equipment deal which US blocked to prevent India gaining additional capability. Further it's not only US, ISRO had quite good collaborative projects throughput Europe and Japan till sanctions due to nuclear tests.

Pressure faced by ISRO was ever nothing like the one faced by India's defence industry.
DRDO now came to a very comfortable stage. They mastered/develop enough technology to create or innovate new products.

Factually incorrect. It was a deal in which Technology transfer used to happen. It ultimately ended with simply supply of Cryogenic engine without technology transfer. We used these engines in our Initial GSLV launches.

Even US had banned Super computer Cry XMP for weather forecast citing the use in defense and space technology. US has a long history of banning many civil use stuff branding them Duel use technology. US has Banned on the name of Dual use technology.

K. Sivan conference at UPES Dehradun on march 12,2021.
I got this via reddit. Many information about upcoming works in ISRO.
  • Heavier Hall Effect Thrusters for completely electric satellites to save weight being developed.
  • Semicryo test facility to be inaugurated later this year. So maybe SCE-200 tests are delayed due to lack of test facilities? But they were planning on testing the engine in Ukraine back in 2019, I think.
  • 1.2 m Trisonic Wind Tunnel being established.
  • PRAVAHA: CFD sovler for Aerothermodynamic analysis under development. They already have an FEA solver called FEAST, I remember.
  • Hypervelocity Impact test facility: For testing space debris impact effects (and designing countermeasures like whipple shields maybe?)
  • Vikram 1601 and 3201 Processors being used. 16 bit and 32 bit processors completely developed and manufactured in India. (Most likely based on 180 nm node)
  • CFC (Carbon Fiber Composites) still remain to be indigenized.
  • Columbium-Halfnium alloy is used in PSLV (had no idea). Industry collaboration for Halfnium sponge.
  • Target for this decade:
    • HLV 16 tons to GTO
    • Vertical Stage Recovery Engine with gridfins and a single liquid engine (probably SCE-200) being developed as a Tech Demonstrator for SpaceX style booster recovery.
    • ^This will progress towards 4 or 5 clustered SCE-200 engine-powered Reusable Booster Stage
    • SCRAMJET propulsion demonstration target of at least 250 seconds of sustained flight yet to be achieved.
    • RLV autonomous landing next.
  • IDRSS being developed for Gaganyaan
  • Chandrayaan 3 next year first quarter
  • Mangalyaan 2 still in Definition Phase, science payloads from students invited.
  • Gaganyaan 1st unmanned mission this year end.
  • ISRO has no collaborations with private Indian industry because they are not yet at ISRO's level. ISRO is doing handholding now, once they grow, ISRO will collaborate with them.

ISRO’s commercial arm NewSpace India Limited (NSIL) has bagged four more dedicated launch service contracts even as it plans to pursue satellite building deals.

NSIL launched its first dedicated commercial mission on February 28, orbiting Brazilian satellite Amazonia-1 from Sriharikota spaceport of the Indian Space Research Organisation (ISRO).

”We currently have four more dedicated launch service contracts, which will be executed in the coming two to three years,” NSIL’s Chairman and Managing Director G Narayanan told.

Found it on reddit it was revealed way back in 2018.
I think we better put spacecraft specific news in specific threads anyway. If everything has to be shoved up in this thread, there was no merit in creating new sub-forum for space program.

Also, I hope other members too post more threads here. For now, most of these are mine or I'm updating those threads.

Chandrayaan-3 launch planned by mid 2022, working on electric propulsion satellites: ISRO.

ISRO Chief Dr Sivan spoke in detail about ISRO`s Chandrayaan-3 (Moon mission 3) and also the ambitious Human Spaceflight programme (Gaganyaan).


While addressing the students and faculty of UPES University, on the ‘Future of Aerospace and Avionics in India’, ISRO Chairman and Secretary DoS Dr.K.Sivan spoke about projects planned for the coming year.


Among the projects he mentioned, he spoke in detail about ISRO’s Chandrayaan-3 (Moon mission 3) and also the ambitious Human Spaceflight programme (Gaganyaan).


“Over the next decade, the Indian Space Research Organization(ISRO) is targeting several advanced capabilities including a Heavy-lift launch vehicle that can carry upto 16-ton payloads to the Geostationary Transfer Orbit (which is four times the current lift capability of GSLV Mk3) and also partially, fully reusable launch vehicles, among others,” Chairman K.Sivan said.


“We have identified, understood the deficiencies of Chandrayaan-2 and taken corrective measures for the next mission, which we are planning for launch within the first half of 2022. Gaganyaan design is in the final stages and project realization has started, all efforts are on for first unmanned mission trial by this year end” he stated.


Elaborating on ISRO’s plans for the upcoming year and the near future he said that payload capability to Geosynchronous Transfer Orbit (GTO) will be increased to 5 tons (an increase from the current 4 tons) using a semi-cryogenic engine on the existing GSLV Mk3 rocket.


Semi-cryo engines burn rocket-grade kerosene and liquid oxygen, such engines are powerful, environmentally friendly and cost-effective.

Dr. Sivan also mentioned the need for a more powerful booster stages (that powers the rocket at lift-off), adding that a more powerful 2000N(Newton) Liquid oxygen and kerosene engine was a work in progress.


The Indian space agency is also making a switch towards environmental-friendly rocket fuels by working on Liquid oxygen-methane and similar green propellants.


Engines powered by methane and liquid oxygen (MethaLOX in short) are widely used in reusable rockets as methane is a clean burning fuel that leaves no residue, as opposed to kerosene. Clean burning ensures that the engines can be reused many times with less or no refurbishment.



“For satellites we are in the final stages of developing a 300mN high-thrust electric propulsion system. This will eliminate use of chemical fuels in satellites and result in lighter satellites by saving on fuel weight” Dr. Sivan said.


He added that India’s first test facility for a semi-cryogenic engine is expected to be ready by later this year and that India had formulated a rocket grade kerosene that they call ‘ISROsene’ (to fuel the semi-cryo engines), which was formulated using the help of Indian industry. ISRO is also working with industry partners on the long-term production capability of this fuel.


Inviting academia and industry to ideate and provide payloads for India’s second Mars Mission Mangalyaan-2, Dr. Sivan said that the second Mars mission project was in its definition stage.

India, Saudi Arabia hold talks on initiating cooperation in space


Bengaluru, Mar 18 (PTI) India and Saudi Arabia held discussions on initiating cooperation in the space field and explored the possibility of inking a county-level MoU.
Indian Space Research Organisation and Saudi Space Commission held a bilateral meeting on Wednesday on virtual mode.


What is the use of having a space program for Saudi..for their researchers in space are going to do prayers 24/7.
Research is an ideology and it conflicts with what saudi has at its core.

India, France working on third joint space mission: Isro chairman | India News - Times of India



BENGALURU: India and France are working on their third joint satellite mission, even as the bilateral space collaboration is entering into multiple domains, including human spaceflight programme, Isro Chairman K Sivan said.
Sivan, also secretary in the department of space, said many French companies are keen to tap into opportunities thrown up by recent reforms injected into the space sector by the Government.
