He also highlighted TRISHNA (Thermal Infrared Imaging Satellite for High-resolution Natural Resource Assessment) is an upcoming collaborative Earth-observation satellite between the Indian Space Research Organisation (ISRO) and the French space agency (CNES). It will deliver high-resolution thermal mapping of the Earth's surface to monitor water cycles, crop stress, and evapotranspiration.

"And the next satellite, Trishna, which is underway, is going to be launched in India next year, providing precise measures of the surface temperature of the world, improving our capacity to handle the water resources, be it in terms of space exploration, journeys in space and new constellations discovered, we have massive projects to pull together. And India will have a major role in the airspace global summit that will take place in September 2026 in Paris," said Macron.

PSLV : SAMOOHA : (?)

SAMOOHA (which translates from Hindi as "group") is an Indian electronic intelligence (ELINT) satellite project. The project was launched in 2023 at the DLRL (Defense Electronics Research Laboratory), DRDO. The U. R. Rao Satellite Centre (URSC) of ISRO (which was also responsible for the sole ELINT satellite, "EMISAT") is also involved in the project. Since this is a defense-related development, virtually nothing is known about it. The information is limited to what is presented in the slide. "Samukha" will be launched in groups of three satellites aboard a PSLV launch vehicle, which immediately suggests a "three-satellite" constellation, similar to the "White Cloud"/"Parcae" systems (U.S.) and an unnamed Chinese system (the trio of Yaogan 9, 16, 17, 20, 25, and 31). The PSLV's fourth (boosting) stage will allow the satellites to be separated by altitude and inclination, ensuring a three-satellite configuration that enables high-precision positioning of radio-emitting sources.

It has been announced that the spacecraft will be equipped with an AIS (Automatic Identification System)—a system used in shipping to identify vessels, their dimensions, and their course. The payload is expected to utilize commercially manufactured components (payload realization industry).

URSC recently posted a tender (technical specifications + contract) for the assembly and testing of three small spacecraft. As we recall, Samukha consists of three satellites. The dry mass of the spacecraft is stated as 500 kg, and the total (fueled) mass as 575 kg. The list of systems is shown in the image. The propulsion system runs on MON and MMH. Overall, the image of the spacecraft from the tender shows a trapezoidal cross-section, just like in the image from the presentation. The appearance of the spacecraft is also very similar.
