NET Late-February / Early-March:
Three launches in Q1: ISRO's upcoming missions in 2024
Hindustan Times Dec 22, 2023
[...]
Officials also said the Nasa-Isro Synthetic Aperture Radar mission (NISAR) — India’s collaborative mission with the US space agency — is also expected to take flight in the first quarter of next year, possibly around late February or early March.

India launches X-ray astronomy satellite
January 1, 2024
[...]
ISRO expects to roughly double that launch rate in 2024, with 12 to 14 launches planned for the year. Among them will be the GSLV launch of the NASA-ISRO Synthetic Aperture Radar (NISAR) Earth science mission, a joint effort of the two space agencies. That mission is slated for launch on March 30, NASA officials said at a session of the Fall Meeting of the American Geophysical Union in December.

Cross-post:
Per NOTAM below, launch NET January 10, 11:30 - 15:30 UTC:
E) GSLV-F14 ROCKET LAUNCH FM SHAR RANGE,SRIHARIKOTA WILL TAKE <snip>
Confirms this will be F14, which leaves F13 skipped (possibly NISAR?)
Highly likely F13 will be skipped over. ISRO has a history of skipping over the number "13" in it's mission numbering. PSLV-C13 and GSAT-13 were both skipped over in this way. NISAR mission should be F15.

I think it is a big mistake for NASA to trust ISRO to launch this payload on their dodgy underperforming "GSLV" rocket. There is still time to switch to a LVM3 or launch on a higher quality American launcher like the Falcon-9 or Atlas-V. At a development cost of $2 billion+ and 10 years in the making a launch failure would be the worst kind of failure for the NISAR program.
Atlas V is retiring, and all 17 remaining Atlas V have already been allocated. A payload cannot be shifted to a new LV instantly. It takes time. For example When OneWeb lost access to Soyuz they announced a switch to Falcon 9 in March 2022, but the first Falcon 9 launch was in December 2022.

NISAR is an equal collaboration between NASA and ISRO and marks the first time the two agencies have cooperated on hardware development for an Earth-observing mission. JPL, which is managed for NASA by Caltech in Pasadena, leads the U.S. component of the project and is providing the mission’s L-band SAR. NASA is also providing the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. URSC, which is leading the ISRO component of the mission, is providing the spacecraft bus, the S-band SAR electronics, the launch vehicle, and associated launch services and satellite mission operations.
As the launch of the joint NASA-ISRO mission is ISRO's responsibility, it would be ISRO's choice to change the launch vehicle.

GSLV was selected as the launch vehicle for NISAR back in 2014. This was before the LVM3 even had it's very first suborbital test launch. Back then the GSLV was the most capable rocket that ISRO had in it's arsenal.
I will agree with you that GSLV is a bit of a underperforming launch vehicle but it is not fair to call it "dodgy" when the current Mk2 variant that is operational has a success rate of 8/10 or 80%. I am confident GSLV will inject the NISAR into it's intended orbit despite whatever reliability issues it had in the past.

Nice! When can we realistically expect NISAR to be launched? Is the March 30th date still good. It was referred to not long back by NASA itself

NET Late-May:
NISAR Launch Delayed to Late May for Further Testing
21.03.2024
The joint NASA-ISRO mission to launch the groundbreaking NISAR (NASA-ISRO Synthetic Aperture Radar) satellite faces a delay, with the launch window pushed to late May 2024.
While the Indian Space Research Organisation (ISRO) has confirmed the designated Geosynchronous Satellite Launch Vehicle (GSLV) will be ready by March-April, the complex radar instrument's final testing and integration into the satellite require additional time.
Prioritizing Pre-Launch Accuracy
The delay prioritizes comprehensive testing to ensure flawless functionality of NISAR's instruments before launch.

Launch is currently expected No Later Then October 2024. If it delays past October, the launch will be No Earlier Then January 2025:
GAO: Assessments of Major Projects

Cost and Schedule Status
[...]
The project has experienced delays during testing due to the late delivery of the spacecraft and technical issues that arose. As a result, program officials told us that they anticipate missing the internal program launch date of March 2024, but they do not expect the launch to be delayed past October 2024. Project officials indicated that there is an eclipse season every year between October and January during which NISAR cannot launch. If the launch were to slip past October 2024, NISAR could not launch until January 2025.
