ISRO News and Updates

Design and Looks wise there is nothing much to talk about Chinese rockets. They looks plain old school.

That outer casing is standard Chinese fashion. Chinese rocekts aren't really old school. They have great modular rocekts with good payload to weight ratio similar to UMLV we are trying to make. CZ is just a nomenclature series.

2021 broke the record of Highest no of launch attempts to orbit and highest no of successful launches.

LOL no. Not even remotely.

New Year Message from Chairman's Desk (K. Sivan)
Not posted earlier.
3 January 2022

A very good morning to all and a warm wishes to you and your families for a happy, healthy and a prosperous new year!

As 2021 has come to an end, I am sure all of us are looking forward for a bright and eventful year.

The beginning of the new year is an apt occasion for reflecting on the achievements of the previous year. During the previous year, the impact of the lockdowns was still evident and activities had to be carried out while following the COVID guidelines and protocols of the
government.

There is a feeling that very little happened in ISRO during 2021. That feeling is primarily due to less number of launches. However, as Chairman, ISRO, I am extremely proud that all of you have made very significant contributions in continuing the operational missions, conceiving many new missions, undertaking many technology development initiatives, and planning for the next decade of space activities.

Over and above that, Government of India successfully implemented the space sector reforms to expand the space sector within India. ISRO's more than five decades of hard work in growing the space activities in India has brought the Nation to an inflexion point, wherein we can leap-frog into a glorious future. This is intended to ensure that India retains its leadership and meaningful position in the global space
Industry.

ISRO engineers have also shown their social empathy by undertaking many initiatives to mitigate COVID induced shortage of medical equipment and supplies through innovative design solutions. The ventilators and oxygen concentrators designed and proto tested by ISRO engineers are now being produced by Industry.

Even on the cultural front, ISRO engineers have shown their mettle by successfully
organizing the Aarohan event, which not only showcased talent but also provided the
right kind of creative avenue to keep morals high in these times. Kudos to all of you!

..........

If you look, at the immediate task at hand this year, we have many missions to execute. Some of these are launch of EOS-4 and EOS-6 on board PSLV. Launch of EOS-02 on board maiden flight of SSLV. Many test flights for Crew Escape System of
Gaganyaan and Launch of the first unmanned mission of Gaganyaan. In addition, we also have Chandrayaan-03, Aditya Ll, XpoSat, IRNSS and technology demonstration missions with advanced indigenously developed technologies on-board. I am sure that with your continued cooperation, support and enthusiasm, we will be able to achieve all the targets.

The last few months were a lull period for ISRO, due to Corona. However, all indicators point towards the next imminent wave. All of us have to prepared and protect ourselves both at the personnel level as well as at the institutional level to safeguard the ongoing programmes and activities. All the Centre Directors have in the past mitigated the aftereffects of previous pandemic wave by excellent planning, devising monitoring mechanism and working protocol. There is a need to tighten our shoe laces in the same manner to face the next wave. I am sure that with the cooperation from all of you, we will be ready for facing any eventuality.

I did not mean they have old school technology. just that they look plain and simple.

I read all over about launches in 2021:

The world just set a record for sending the most rockets into orbit | Ars Technica

More rockets made orbital launch attempts during 2021 than in any previous year in history, breaking a record that dates back to the space race.

There are no official records of such matters, but several good online resources provide a compendium of data that includes both orbital launch attempts and successes. Based on this information, a total of 144 orbital launches were attempted in 2021, of which 133 were successful. This total does not include two unannounced launch attempts by Iran's Simorgh vehicle.

FURTHER READING
This may finally be the year we see some new chunky rockets take flight
Last year's numbers surpass the total orbital launch attempts in 1967 (122 successes out of 139 launch attempts) and a previous record for successes in 1976 (125 successes out of 131 attempts).

So clearly there are no Chinese ventures similar to American space Inc. as I asked you. US anyway holds an industrial capacity for 100+ launches. PRC has a long away to go. India will take even longer.

Chinese rocket companies are preparing for hop tests - SpaceNews

A number of Chinese rocket firms are preparing to carry out first hop tests in a bid to develop reusable launch vehicles.

So, we can see G1 mission quite soon this year but second unmanned missions (with all parameters) and first human mission might be delayed.

Yep , if all goes according to plan then G2 in 2023 & manned G3 in early 2024

has the training of astronauts completed ??

and any updates on our space station

What about IDRSS?

They haven't published any update.

and any updates on our space station

In planning stage yet. Everything is theoretical because SPADEX mission.

 

[Vamsi]

What about IDRSS?

We can use foreign satellites for the 1st unmanned mission. I guess IDRSS-1 will be launched this year, while IDRSS-2 next year. Let's wait until the Annual Report is released

They won't risk launching IDRSS on GSLV II till it has next two consecutive successful launches.
Though the way they are in haste, I agree that they may not shy away from using any foreign systems for communication now.
BJP would love to acquire browny points for elections in early 2024. At least sending humans in space would garner some more attention than Chandrayaan-2, simps have already started to publish rubbish like "Can Modi become the Kennedy of India?".

$10 billion budget in 5-6 years is pathetic and peanuts.

 

[Akula]

$10 billion budget in 5-6 years is pathetic and peanuts.

Per year.

 

[Indx TechStyle]

Per year.

Impossible for 10 years. Even ESA's annual budget doesn't exceed $8 billions.

#PSLV_C52 Mission!!
India started final preparations for it's #first space mission in 2022.
The EOS-4 aka #RISAT-1A (New and old nomenclature) already reached SDSC, Sriharikota from UR Rao Satellite Centre in Bangalore using a specialised vertical transport container. Probably the new RISAT-1A will act as a replacement satellite for the retired RISAT-1 satellite, which mysteriously stopped working after unknown reasons.
The new indigenously built X- band SAR mounted satellite is classified as a earth observation satellite(EOS) having a resolution of less than 0.5m and able to take pictures even in adverse weather conditions!

Does anyone have any info on the turbopump design and status ?
For a closed cycle engine like the sce 200 that would be the hardest to make .. If this turbopump can survive in oxygen rich combustion making things like the Kaveri hot stage would be trivial .

 

[Love Charger]

What ever they do !, Do in secreacy until success is confirmed.
Negative publicity from a failure will be very hard to handle

I completely disagree .. if "criticism" from a few jahil morons is too hard to handle forget about ever progressing in anything.
A closed cycle engine is peak engineering, if they get this right it would up there among the best engines in the world. I was so happy to hear that ISRO is attempting this .. it should be an inspiration for every science enthusiast in our country .
However I suspect (my speculation)that secrecy is due to Ukraines involvement which they probably wanna keep hush hush to avoid dealing with MCTR issues .
