Internship at ISRO

Hello all! I am currently in my final year in BTech in ECE from tier 2/3 college. I'm looking to get an internship at ISRO. My CGPA is 9.6. As I'm looking at the list of ISRO centres, I have a doubt - do all these cnetres have same acceptance rate or do some of them don't have strict selection standards? I've already mailed a few professors from IITM(since I'm studying in Chennai) and other IITs but never got a reply. Connected with one of those professors but he ghosted me after a while so I'm not really sure if I'll be getting this internship as well. Could anyone suggest any particular centre good for Signal Processing internship and with good acceptance chances? I have a little research experience within my college, getting a paper ready to publish.

Want to work with isro.

I am currently working in a non IT field. But want to switch to IT and willing to work with isro. I am also learning about machine learning, specifically with CVision. I have just made projects but not a industry level experience. But I want to work with isro. And as there are no vacancies right now, so any suggestions how can I join ISRO through any scientist reference and how to contact them. Or any other way. Any suggestions please.

The configuration has changed once again and now LVM3 will launch both modules.

Target 2027 is way too optimistic and near 2029-30 is better estimate.

Can we know who ISRO tenders were awarded to?

Hello, I was wondering if there's a way to know which ISRO tender was awarded to whom? The vssc eprocure site just has tenders and not the award of tenders.

Thanks in advance!

Urgent Query: SDSC SHAR Internship Acceptance mail Confusion

I received an Internship Acceptance E-mail from the Human Research Department of Satish Dhawan Space Centre SHAR, Sriharikota. They asked me to acknowledge the mail for further processing and said that they would send the confirmation letter shortly via E-mail only on the basis of the availability of slots. So I sent them an acknowledgement email revert but I am confused that is it 100% sure that I got the internship or do I still have to pass through any sort of screening process?

Indian Astronauts to Visit Space Station Soon: NASA Chief Shares Major Update on ISRO Collaboration

NASA has announced it will help train two Indian astronauts, with one set to travel to the International Space Station (ISS). This marks a significant deepening of collaboration between NASA and the Indian Space Research Organisation (ISRO).

Key Highlights:

  • Joint Mission: An ISRO astronaut will join the ISS, a historic step in US-India space relations.
  • Training Program: Two astronauts from ISRO will undergo advanced training at NASA's Johnson Space Center.
  • Strategic Initiative: The iCET Dialogue between US National Security Adviser Jake Sullivan and Indian counterpart Ajit Doval outlined plans for increased cooperation in space.
  • Future Objectives: This partnership supports upcoming human spaceflight missions and aims to enhance life on Earth.

Bill Nelson's Statement:

“Building on my visit to India last year, NASA continues to further the United States and India initiative on Critical and Emerging Technology for the benefit of humanity. Together we are expanding our countries' collaboration in space, to include a joint effort aboard the International Space Station with an ISRO astronaut.”

This announcement highlights the growing partnership between NASA and ISRO, promising significant advancements in space exploration and technology for both countries.

What is the approach to join ISRO?

I am in ECE 2nd year BTech and want to go for ISRO and I'm a little confused as to how to get in, is it through GATE and ICRB or only through ICRB? Would a GATE approached prep be enough for ICRB?

Urgent doubt related to branch/college in order to join isro.

I have been aiming to work at ISRO for very long now. My initial plan was to go to IIST but I unfortunately did not do well in JEE advanced. Now since I'm simply going to choose the best college I can get, I was wondering whether branch matters more than college? I only know that ISRO selects candidates through an exam conducted by ICRB. Do they select Computer science engineers only? And if I have to choose between CSE in a teir 3 college and any other branch in some better college, which one should I go for? Does or would ISRO select candidates from IT, AI & ML or Data Science background? Anyone with experience or a definite answer, please reply.

Physics PHDs who aren't doing postdoc what are you doing right now

Just curious about scope after phd without postdoc ,i am interested in physics but engineering seems more narrow (of course professional course) but physics seems familiar but not industry ready and scared of jobs after engineering as i have very narrow interest ISRO,DRDO,RAC,BARC , wondering physics is more suitable or not

myquals: 12th 85% interested in technical jobs that involves physics and cs

A talk on "Launch Vehicles and Propulsion System" by Dr. V. Narayanan (Director, LPSC) on 14 June 2024

"Launch Vehicles and Propulsion System" by Dr. V. Narayanan (Director, LPSC) on 14 June 2024

Note: The YT channel of IIRS ISRO Digital Learning Programme is dropping lots of useful videos.

Some of the information is same as this recent lecture of his.

https://www.youtube.com/watch?v=p0RgJpNJq-U

@47:31 New SC-120 readiness timeframe given as "may be 2 years from now" i.e June 2026

@51:01 On upcoming Kerosene based scramejet test flight

that time only we ignited and sustain the ignition, in couple of months we are going to demonstrate this technology for 250 seconds continuously you will hear the news very shortly maybe in two to three months time the development work is going on in the advance level.

So it looks like a full fledged HAVA test? May be chairman incorrectly mentioned that a sounding rocket will be used and it will use Test Vehicle instead?

A slide on various Gaganyaan Test Vehicle flights. (Relevant thread)

  • Transonic condition: Mach 1.2 (TV- D1)- launched 21/10/23
  • Supersonic condition: Mach 1.4 (TV-D2)
  • Max. Dynamic pressure condition (TV-A1)
  • Max. Mach condition : ~ Mach 2.2 (TV-A2)

Last slide with lot of ambitious stuff they hope to pursue.

SR-0/SSLV-D3 Mission

New Satellite Alert: For Amateur Radio Operators and Satellite Trackers

Space Rickshaw-0 DemoSat Mission (SR-0), planned for launch onboard SSLV-D3 from SHAR, India. NET July 10. (launch date yet to be confirmed)

Mission Goals:
Spacecraft (SR-0): Two Educational/Amateur Radio Payloads from Customers. Spacecraft Manufactured by Space Rickshaw.

Deployer-X (SR-1): The main goal is to demonstrate the in-house developed nanosatellite deployer called Deployer-X, a pin-based non-canister separation system, weighing just ~400 grams for deploying up to 4 kg of payload, making it one of the lightest deployers ever developed for nanosats. It will deploy SR-0 as part of our space qualification campaign. The mission also demonstrates in-house developed HDRM and spacecraft separation sequencer. More details will be up on our website by next week. https://spacerickshaw.com
