FAILURE: GSLV Mk II F10 - EOS-03 (aka GISAT-1) - SLP - 12 August 2021

Another question to ask: does the fairing’s new ogive shape have to do with weight reduction?

Something’s telling me that the new fairing is being constructed with lightweight material.

Something’s telling me that the new fairing is being constructed with lightweight material.

The new payload fairing is made up of composite material so yes it will be lighter. But main benefits of new payload fairing will be increased payload bay space and reduced aerodynamic stress on the vehicle during the atmospheric phase of flight. The GSLV Mk-3 also underwent a similar change between the X and D1 missions with it's heatshield also being changed to a composite based ogive design.

So, PAM-G still planned onboard?

I think they choose the fairing materials as per payload mass requirement to optimise cost and time.

No. It was removed several years ago and onboard propellant of GISAT-1 was increased by around 1000kg to compensate.

As per local media GISAT-1 has arrived at SHAR and is aiming for launch in late january

So....will there be any ISRO launch this month (or the next) at all?

ISRO's official stance is that this will still launch before the end of the month however sources from the launch site are saying that a mid february launch is more likely given that launch campaign only began in early december.

[K210]

Local media is saying that launch has been delayed to february.

GISAT-1 is currently expected to be launched no earlier than February 12, 2020

[Galactic Penguin SST]

So, erm, any NOTAMs or other notices for this flight yet?

Nope. Complete silence from ISRO regarding this launch so far.

Given that source is a personal blog i would take that date with a grain of salt, unless of course the owner of said blog has inside sources at ISRO

श्रीहरिकोटा स्थित सतीश धवन अंतरिक्ष केंद्र (एसडीएससी) शार, में भू-अवलोकन उपग्रह जीआइसैट-1 के प्रक्षेपण की तैयारियां चल रही हैं। इस उपग्रह का प्रक्षेपण इसी महीने के अंत तक होने की संभावना है। इसे भू-स्थैतिक प्रक्षेपण यान (जीएसएलवी-मार्क-2 एफ-10) से लांच किया जाएगा।

Preparations are underway to launch the Earth Observation Satellite GIAT-1 at Satish Dhawan Space Center (SDSC) SHAR, Sriharikota. The launch of this satellite is expected by the end of this month. It will be launched with a Geostationary Launch Vehicle (GSLV-Mark-2F-10).

Apparently currently scheduled on March 5 at 12:48 UTC (18:18 LT).

First pictures coming from Shriharikota of the Assembly of GSLV MK2 F-10(looks like a picture from dec-jan).
The launch is on 5th March.

This article apparently points to a 11:55 UTC launch time (thanks NSF member Ohsin for the translation).
