Two sets of S85 Motors (SSLV first stage) under preparation. One for static test in November another for D1 flight in December.

Cross-post:
Next launch is PSLV C50 with "CMS 01" followed by first SSLV with "EOS 02" and GSLV F10 with "EOS 03".

PSLV-50 is now scheduled for December 14, so that is the NET for SSLV first launch.

He [K Sivan] said the first test-launch of Small Satellite Launch Vehicle (SSLV) or mini-PSLV and a technology demonstrator test of the reusable launch vehicle (RLV) will also happen next year.

Neither am I.  This could indicate a ballistic missile launch.  I am cross-posting to the Indian sub-orbital launch thread.

EDIT: Whatever did or did not launch, it was not SSLV.

Cross-post:
Also, FLP may not be occupied by SSLV as this rocket is on-demand and can be stacked up at the very end. I believe, they will use the new buildings developed as part of PIF project.
What is the PIF project?

My assumption was that FLP needed substantial alterations to perform the first SSLV launch campaign, as well as extensive testing.  I also assumed that this work would preclude other launches until after the first launch.

What is the status of this work?

PIF project is part of series of projects to ultimately increase launch rates to that of foreign nations. There are some threads this section that have news posts regarding the overall upgrade programme. SSLV AFAIU uses a milkstool adapter like the RLV and other test rockets use and  only requires LUT upgrades to provide the necessary connections.

Multiple sources in ISRO said on Thursday SSLV-D1 is targeted to be launched towards the end of March or early April -- most likely in the first month of the financial year -- though no firm date has been set so far.

According to sources, GISAT-1 will be followed by the maiden flight of Small Satellite Launch Vehicle, ISRO's compact launcher, likely in April.

Did the static fire occur?

Cross-post; I draw the conclusion that the D1 scheduled launch will be substantially delayed--launch TBD:
S85 (First stage motor) static test failed due to design issues

Quote
The static test of first stage solid motor (SS1) of ISRO's Small Satellite Launch Vehicle (SSLV) -- a new-generation compact rocket -- was not successful, according to sources in ISRO. "Oscillation was noticed after 60 seconds into the test and nozzle was blown out near the bucket flange where it's attached with the motor at around 95 seconds", sources in the Bengaluru-headquartered space agency said.

Quote
It was supposed to be tested for a total duration of about 110 seconds, officials said.

Quote
New motor has to be static tested on the ground to prove its performance. If it is successful, one more of the same configuration is tested again for acceptance.

If both are successful, no more ground test is required and third motor of the same configuration will be accepted for flight", an ISRO official said.

ISRO is preparing to repeat the engine test that failed in March. Launch still planned for Q4 2021 or "before the end of this year". Translated to real time, this probably means 2022.

The Indian Space Research Organisation is gearing up for its first developmental flight, a new-generation compact rocket which is scheduled to be launched in the fourth quarter of the year 2021. Hence, according to the officials, the Indian space agency is all set to test the solid-fuel motor of the small rocket which is under development.

The official also said the space agency is planning to fly the small rocket -- Small Satellite Launch Vehicle (SSLV) -- before the end of this year itself with an Indian earth observation satellite.

A repeat of already-known news, but worth cross-posting nonetheless:

On August 4, Union minister of state for space, Jithendra Singh had told Nama Nageswara Rao in Parliament that the PSLV rocket, numbered C52, would launch EOS-04 in the third quarter.

In fact, four EOSes were to have been launched in the last two quarters.

Apart from PSLV-C52, according to the minister, the GSLV-F10 was to launch the EOS3 in the third quarter followed in the fourth quarter by the first developmental flight of the Small Satellite Launch Vehicle, SSLV-D1 with the EOS-02 and the launch of EOS-06 aboard the PSLV-C53.
