There are no old or new designs yet and won't till project finalises. These are representational pictures used by ISRO personnel during presentations.
Those designs were from 2015 atleast if not earlier, in those concepts the core alone version uses a SC400 core stage and C-27 upper stage and can carry only 11.4T to LEO, while the latest designs shown by Dr. Somanath uses new SC90 as second stage and replaced old C-27 with C-34 as the upper stage, in this new config it can carry 28T to LEO in Expendable mode and 22 T to leo in reusable mode which is a significant improvement when compared to that old design, which also shows that isro is improving their concepts every year.

Those aren't designs, those are configurations. Engines don't have designs yet and no rocket configuration was ever ruled out.

ISRO has options to

1. keep up with PSLV/GSLV/LVM3 as it is and just develop one or two HLVs to add in family,

2. redesign and release a series with interchangeable parts (UMLV). Would add more development time and cost. or
3. mastering reusable technologies to replace all the systems with RLVs or various paylods. Will need even more time

All options are open.

Since even SCE-200 isn't flying yet and barely any engines and motors of concepts have been worked upon, all of the suggestions and concepts by various managers at DoS keep on repeating.

All we know that there plans of 16-22T GTO capacity HLV or 60-100 tonnes LEO cap HLVs for long term. Only official confirmation is a 16 tonnes GTO cap GSLV since we heard that it entered project phase this year (might fly around or before 2030).

Dozens of designs or super heavy launchers and reusable space shuttles have been discussed and thrown in archives in ISRO for past 10 years.

Looks like ISRO is having a bit more trouble.


Some excerpts:

Ajey Lele, senior fellow at Manohar Parrikar Institute for Defence Studies and Analyses, said: “It is critical for Isro to quickly conduct the SSLV launches; they have been delayed for far too long. It will be a commercial satellite and some of the slots even in the development flight has been booked by foreign agencies. If the launches do not happen soon, they might move to other launch service providers and Isro will lose market.
All three atomic clocks – one main and two back-ups – on the first satellite of the constellation IRNSS-1A failed, prompting the space agency to launch a replacement satellite IRNSS-1H (which failed) and IRNSS-1I (which is currently working). Officials from the space agency also confirmed that the failure of the atomic clock has affected more satellites.
The NVS-01 satellite is to replace the IRNSS-1G satellite that was launched in 2016 and has a mission life of 12 years. The NVS-01 replacement satellite was to be launched on board Isro’s Geosynchronous Launch Vehicle or GSLV, the same one that failed this August. Four of the fourteen GSLV missions so far have failed.
Challenging times for ISRO, for sure. Let's see how the government and new ways of working with private players can get them out of these troubles.

They need to do so many things:
1. New leadership.
2. Revamped Team structure.
3. Much Much More Funding.
4. Much Much more work force
5. Ditch ages old hardware and systems used in their offices, labs, etc.

Why the hell ISRO staff wearing white Lab Coat we used to wear in Chem labs in school, in the Launch control centers??????

I don't see any other country doing this BS!

Just see the recent Tianzhou-3 launch from China. Extremely professional dress and setup of the whole Control Center. Almost beating US and Russia in that.

Yup…I am saddened too. The very passive policies of ISRO, internal sabotages like the Nambi Narayan episode, the Antrix-Devas debacle, not much focus on S&T by BJP, etc are also further reasons for this sorry state. The challenge is how to get out of it. What can be done to turn the ship around? I think this government’s focus is much more on DRDO military applications than in civilian science sectors. ISRO is going to struggle for a while now - that much is certain.

Mangalyaan/Mars Orbiter Mission has completed 7 years in orbit!


India's Mars Orbiter spacecraft has completed seven years in its orbit, well beyond its designed mission life of six months. "Indeed, a satisfying feeling," K Radhakrishnan who as the then Chairman of Indian Space Research Oranisation (ISRO) led...

( btw, one really ignorant comment in the comments section, about not having seen one single photo taken by this satellite)

It's quite irritating watching @RoaringTigerHiddenDragon and @SKC littering the thread.

If you guys don't have anything beyond this quality, why you don't restrict yourself to YouTube and FB comments whinning? There are plenty of video game addicted teenage SM warriors just like you with such quote quite such simple solutions for any sort of problems.

This thread was created for general "news & updates" and has bee found spammed by street stormers in 8 out of 10 notifications.

^ Still, some legitimate criticisms can be, and have been made, about ISRO's functioning.

I think we shld ask govt, what happened to ISRO, hw suddenly collapsed.
It's not the Government's fault that there are launch failures, and Chandrayaan landing failure happened.. That would lie at the feet of the current ISRO leadership.. and the project team..
