SRO announces NISAR Utilization Programme,  a chance to access & analyze data from the 🇺🇸🇮🇳NASA–ISRO Synthetic Aperture Radar (NISAR) satellite mission.

NISAR offers high-resolution imaging & aims to study Earth's ecosystems, cryosphere, solid earth science, and coastal ocean processes to address global environmental changes & natural hazards. 🛰️🌿https://isro.gov.in/NISARSatellite.html

Indian researchers can submit project proposals on diverse applications like agriculture, forestry, disaster management & more using NISAR's L & S-band SAR data, by Oct 31, 2023.

Funding support is available for selected projects.

Before #NISAR begins its Earth-observing mission, the spacecraft must prove it can withstand the harsh environment of space.

At an @ISRO facility in India, NISAR underwent 3 weeks of intensive thermal vacuum testing – and met all of its requirements! ✅

Meaningless video just rehashing information one can find on Wikipedia. Lazy journalism at it's finest.

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.

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.

So delayed 3 months or more? What launches can be expected between now and June?

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:

Quote
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.
