I'm not aware that, that manifold assembly is for water pumps or something else like propellant/gas/air or any other couplant?

The red colour is a dead give away that it's a water deluge system.

You cannot randomly paint pipelines as per your wish.We have to follow a common standard.In India Yellow color is used for hazardous gases,blue for air and red for water deluge/fire fighting system.

This is what it looks like

Even though there is a LMV thread, this video deserves to be here:-

One question i have why isro didnt use gslv mk2 for oneweb launch. Capacity to LEO is qualifying for mk2 also ?

Maybe the track record of GSLV mk2 is problem for customers

Does Mk2 has any future now?

I think we will continue with the current configuration of LVM instead of Mk2.

I think same, it should be retire now.

GSLV Mk-2 payload capacity is 5 tons to 22deg 300KM LEO .....while LVM3-M3 carried 5.8tons payload to 450KM 88deg inclination orbit .....so technically GSLV-MK2 cannot carry Oneweb payload to required orbit...hence not used for this mission....also it's less reliable than LVM-3, it has too many points of failure...

btw GSLV-F12/NVS-01 is planned for NET May 24,2023 as per NASA space flight forum

nah it has been booked for 10 more launches atleast before it retires ..

upcoming payloads for GSLV are
NVS-01/02/03/04/05
INSAT-3DS
NISAR
GISAT-2
IDRSS-01/02

Ok, that's a technical reason.

Can anybody compile this interview. I am not able to understand.

 

[TopWatcher]

Some pvt company should come up with these launches capabilities otherwise ISRO not able to work on science.

The MK-2,i find to be the strangest rocket in operation anywhere in the world. A Solid core and a Hypergolic Boosters,the core dies out before the boosters because of which they have to carry the weight of the dead core stage for almost 1 minute.

Our scientists knew this flaw, but they were forced to choose this configuration because of lack of funds....

Dr.Nambi Narayanan during Vikas Engine development program, proposed to build a test stand to test 4-Vikas engined L220 core stage...that test stand proposal was rejected by Prof. Satish Dhawan,who later accepted that it was his mistake....

had they build that test stand .....we would have had LVM3 capability in early 2000s itself, lack of funds & Prof Satish Dhawan's reluctance has pushed our Space Programme by 2 decades...

Yes I was mentioned in some book i remember

PSLV-C55 will have atleast 10 experimental payload in PS4-OP module that literally means 10 separate experiment will be conducted on it although it's been vouched as commercial mission
