I'm currently in grade 10, and i was wondering if it is possible to do internships in class 11 in ISRO or any other institute. I'm willing to do home schooling in grade 11 and 12 so that in the meantime I could gain work experience through internships. I would like to know if it's possible to do so? And if not then what are the qualification to meet the criteria. I'm also willing to give NSEA this year and Jee in 2027.

I am from India and have received an offer from the International Space University in France for their 18-month Masters of Space Studies program, which includes internships. I am passionate about space studies, but I am not very familiar with the university or the job market after completing the program. Can anyone provide information about the university/course and the job prospects/career opportunities afterward? I would highly appreciate any advice.

Will both SpaDEx satellites be deployed at the same time or will PSLV deploy one satellite followed by a PS4 restart/burn and then deploy the other twin?

What is the future of contract Engineers presently working in ISROs various departments with btech degrees working 12Hrs many times in a week working in holidays also specially ISTRAC contract Engineers not getting paid much.

Is it fair for the very prestigious organisation of INDIA to treat such employees like this.

Also behaving with them like they are some kind of illetrate worker treating like labours and such but some scientists do

And many times we do all the critical work they just attend the meeting and take all the credit in which we are not welcomed . And guess what we are not even got appreciated by them . Why do they treat us like that it is not professionalism i can bet you for that its just big ego of a guy just got promoted to so called scientists from a iti Technician i mean wtf 😒.

It was my dream place to work for but i am just changing my mind now please help me with your suggestion if any of you guys are scientists in isro please don't get offended as i face this problem that's why iam writing this post.

If any of is Scientists who cleared ICRB please help me or should i focus be a good contract Engineers as some kind of plans GOI have for us or ISRO,DOS or SPACE FORCE have for us PLEASE HELP 🥺 i respect every part of that campus.

Saw a previous post mentioning that ISRO is requesting industry partners for its development. I somewhat understand the importance of its secrecy but knowing DAE will it be unveiled in the last moment? I do not see good science being made for significantly long duration on the upcoming moon/interplanetary/deep-space missions without it.

So I am kinda expecting there to be at least a planned demonstrator mission for the 5W/1W version before the next Chandrayaan in 2027-28 (assuming ISRO is planning on chucking it in :P). Are the different power capacity units developed side-by-side? Any new info will be appreciated

What is the fundamental difference between the batteries used by lander of JAXA and rover of ISRO?

Why was it that while JAXA lander survived and restarted after its power ran out but ISRO'S froze?

Was it just a temperature difference or did JAXA create a new kind of batteries?

The tender is about EOT cranes but I was more interested in the facility itself which appears to be related to dedicated R&D project on additive manufacturing at VSSC.

Full form of ReDAMS = Research and Development in Additive Manufacturing for Space at RFF, VSSC, Thumba (RFF = Rocket Fabrication Facility at VSSC) (Source [PDF] [Archived])

From DDG (DoS) 2023-24 [PDF] (Pg. 165) we have ₹7.56 crores allocated for it.

Building for additive manufacturing for Redams facility at RFF (project re-dams)

The layout of ReDAMS facility is provided in tender. [PDF] [Archived]

We can see it has floor space for these three AM processes along raw material storage/processing and post-processing areas:

• Electron Beam Additive Manufacturing (EBAM)
• Direct Energy Deposition (DED)
• Wire Arc Additive Manufacturing (WAAM)

Few highlights from summary.

Space Transportation:

• Launch of GSLV–F14/INSAT-3DS mission was successfully accomplished on February 17, 2024 at 17:35 hrs from SDSC.
• Vacuum ignition test of CE20 E13 cryogenic engine HT-08 successfully conducted for a duration of 2.5 seconds in High altitude test condition at TCT, IPRC on February 13, 2024. With this test, human rating of CE20 engine powering the Human rated-LVM3 vehicle for the Gaganyaan programme has been successfully completed.
• Qualification hot test of the PS4 engine nozzle divergent realized out of Satellite alloy for the restart mission was successfully conducted for a duration of 480 seconds in High altitude test configuration at IPRC on February 14, 2024. The replacement of columbium alloy with indigenous Satellite alloy for realizing the nozzle for the fourth stage of PSLV (PS4) is expected to bring in substantial cost savings.

Human Spaceflight:

• Strain gauge bonding activities completed on G1 Crew Module hardware. PUF filling and Vapour Barrier Coating activities also completed in apex region of the Crew Module.
