r/ISRO

I gave written exam for a post in SAC ISRO. It is not centralized recruitment but specific by sac, isro. The post is for scientist C atmospheric sciences and oceanography. There are 8 posts available. So, approx 40 students shall be called for interview.

My question is what kind of marks are needed to get interview (to get into top 40, or top 10).

What is historical data. I can't find anything on Google.

I'll appreciate if anyone can give insights.

Do scientists who join as scientist C or D get to travel abroad for training purposes?

With the recent boom in the Indian space industry I'm left wondering what do you guys think is the blueprint of the future of space exploration in India? Like how likely is it that india has its first manned space mission in the next decade or so?

Hey everyone, so I am a BSC graduate and I am also preparing for various gov jobs

Can anyone tell me about the level of this exam , is it around ssc level or Banking level

And does anyone know , what was the previous ( previously whenever this vacancy came ) cutoff

Thank you

I applied for the ICRB ISRO recruitment (Advt. No. ISRO:ICRB:01(A-JPA):2026) and paid the ₹500 application fee on 14 August 2026 through UPI/GPay.

The payment receipt initially showed SUCCESS. I also checked the SBIePay transaction tracking page, which shows:

• Transaction date: 14-Aug-2026, 22:19:52
• Amount: ₹500
• Transaction Status: IN CLEARING
• Transaction Status Description: “Transaction is successful further processing is in progress”
• Settlement Date: -

However, when I log into the ICRB application portal, it still says:

>

I also received an email from ICRB saying that my application is incomplete and/or the application fee has not yet been paid.

I have already raised a payment-status complaint through the portal, but I'm worried because the deadline is 16 August 2026 at 11:55 PM.

Has anyone faced this with ICRB/SBIePay before? Does “IN CLEARING” usually get updated automatically, and should I simply wait for the payment to be reconciled, or is there anything else I should do before the deadline?

I don't want to make another ₹500 payment and end up with a duplicate transaction.

I have enrolled in AI/ML course and now I want to know how can I be a AI/ML Engineer in ISRO?

Any exam ? I don't know how to join as ai/ ml Engineer in ISRO.

India, according to an analysis of more than six decades of space missions, simply does not launch often enough to bring its costs down.

India spends more to put a kilogram of payload into orbit than any other major spacefaring nation, marring its public image as a cost-effective launcher, according to a new peer-reviewed analysis of more than six decades of rocket launches published in Economics Letters.

The authors, Alessio Terzi of the University of Cambridge and Francesco Nicoli of Politecnico di Torino, estimate that it cost $13,302 to send a kilogram to low-earth orbit on Indian rockets in 2025 — higher than Europe ($9,897), Russia ($6,682), China ($5,809) and Japan ($5,287), and the U.S. ($3,225). The global average was $3,868.

So I was trying to fill the form for sc but it was asking for a gate score and so I was thinking if they conduct a cbt

Is there a pattern change now or should I fill a different form for the cse branch

I would like to know if there is any other isro form for cse pls guide me thank u

Hi all,

Is it a good option for a fresher to join ISRO in a contractual position? The contract is for 1 year and 1 month. How likely is it that the contract will be extended after that period? Is extension or continuation possible? also how is the work there like do we get to do development if hired as an engineer or is it more about back office work

On utilization of semi-cryogenic engine (SE-2000)

> The recent successful testing of the Power Head Test Article for the 2000kN semi-cryogenic engine at a thrust level of 88% is a major milestone in the indigenous development of Semi-cryogenic engine, which has given sufficient confidence to proceed towards the demonstration of steady state performance of engine powerhead at 200 tonne (100%) thrust level. Further, the qualification of the fully integrated semi-cryogenic engine will ensure self-reliance in high thrust liquid propulsion engines. > > The Chandrayaan-4 Sample Return Mission proposes to utilize the LVM3 launch vehicle incorporating the Semi-cryogenic engine. The Gaganyaan missions will be launched with human rated version of LVM3 with core liquid stage (L110). The need for Semi-Cryogenic engine does not arise for Chandrayaan 5 mission, as it is a joint mission with JAXA, wherein ISRO will develop the lander and launch is under the scope of JAXA. > > All the engine subsystems have been successfully realized except one subsystem i.e. thrust chamber, which is taking some more time to fabricate, owing to its significant complexity. As of now, the Power Head Test Article consisting of all the integrated engine subsystems except the thrust chamber have been tested up to 88% thrust level and further activities are in progress towards the demonstration of steady state performance of engine powerhead at 200 tonne (100%) thrust level. > > The next generation launch systems are based on LOX/Methane engines and does not require the Semi-cryogenic engine.
