1. ISRO Completes Gaganyaan Crew Module Separation Tests
Update date: 16 October 2026
The Indian Space Research Organisation (ISRO) successfully completed a series of Crew Module-Service Module (CM-SM) separation tests for the Gaganyaan human spaceflight programme. The tests were designed to verify the performance of the system that separates the crew capsule from the service module before the capsule re-enters Earth's atmosphere.
The tests were conducted using a specialised setup at the Vikram Sarabhai Space Centre in Thiruvananthapuram, Kerala. The arrangement simulated the combined module and tested the separation process, including the disconnection of electrical and fluid-service connections between the two modules.
Why are these tests important?
Gaganyaan's orbital module consists of two main sections:
- Crew Module (CM): The section designed to carry astronauts and provide a protected environment during the mission.
- Service Module (SM): The section that supports the crew module during the mission through associated systems and services.
The modules remain connected during launch and the orbital phase. Before atmospheric re-entry, the crew module must separate from the service module in a carefully controlled sequence.
ISRO reported that the tests validated the separation system's design and demonstrated the ability of important crew-module subsystems to withstand the associated mechanical shocks. These included avionics, inertial navigation systems, thermal protection components and systems related to temperature and humidity control.
The tests support preparations for the first uncrewed Gaganyaan mission, designated G1, which ISRO stated was targeted for launch in 2026.
Exam Point: Gaganyaan is India's human spaceflight programme. Remember the roles of the Crew Module and Service Module and the importance of safe separation before re-entry.

2. Quantum Technology: ₹150 Crore Support for QNu Labs
Update date: 16 October 2026
The Technology Development Board (TDB), under the Department of Science and Technology (DST), signed an agreement with Bengaluru-based QNu Labs Private Limited for ₹150 crore in financial support under the Research Development and Innovation (RDI) Fund.
The project has a total estimated cost of ₹300 crore. Its objective is to develop an indigenous technology foundation for India's Quantum Secure and Sensing Networks. The support will be provided through optionally convertible debt, rather than being described as a direct grant.
Four areas of technology development
- Identity security: Developing hardware-based methods to establish and verify the identity of devices.
- Location integrity: Working on trusted navigation technologies and methods to detect manipulated positioning signals.
- Network security: Advancing quantum-secure communication, including quantum key distribution.
- Time integrity: Developing high-precision timing and secure time-synchronisation systems.
Quantum key distribution (QKD) uses principles of quantum physics to establish cryptographic keys. It is being developed for secure communications, although practical deployment depends on the technology, infrastructure and application involved.
The programme aims to advance technologies from Technology Readiness Levels (TRL) 4-5 towards TRL-9. TRL-9 generally represents a technology demonstrated in an actual operational environment.
Exam Point: TDB operates under the Department of Science and Technology. The QNu Labs agreement is associated with the RDI Fund and indigenous quantum-secure technology development.

3. Scientists Identify Terrestrial Sites Similar to Mars
Update date: 16 October 2026
Indian scientists reported the identification of geological locations that can serve as terrestrial analogues for studying Mars. The findings involve sites in Tamil Nadu and the Atacama Desert region of Chile.
A terrestrial analogue is a location on Earth that shares selected geological, chemical or physical characteristics with an environment found on another planetary body. Researchers use such places to investigate how minerals form, how rocks interact with water and what those processes may reveal about past environmental conditions on Mars.
Which minerals were identified?
| Mineral | Location | Scientific relevance |
|---|---|---|
| Melanterite | Neyveli, Tamil Nadu | Helps researchers investigate mineral formation and water-rock interactions. |
| Gypsum | Tiruchirappalli Badlands, Tamil Nadu | Provides a terrestrial comparison for studying mineral deposits and past environmental conditions. |
| Gypsum | Atacama Desert, Chile | Offers another Earth-based location for comparing geological processes relevant to planetary research. |
The research used advanced analytical instruments, including a laser Raman spectrometer. The instrument helps identify minerals through their characteristic interaction with laser light.
The research was supported by scientific infrastructure established through the Department of Science and Technology's Fund for Improvement of S&T Infrastructure (DST-FIST) at the Department of Geology, University of Kerala.
Earth-based analogue studies are useful because orbital observations alone may not provide enough information to fully characterise minerals and their formation processes. Researchers can examine terrestrial samples directly and compare them with observations of Mars.
Exam Point: Melanterite was identified at Neyveli, Tamil Nadu, while gypsum was identified at sites in Tamil Nadu and Chile. Remember that terrestrial analogues are used to study planetary environments through comparisons with Earth.

4. Indigenous 32-Slice CT Scanner Development
Update date: 15 October 2026
The Technology Development Board, Department of Science and Technology, signed an agreement with Panacea Medical Technologies Private Limited, based in Malur, Karnataka, to support the development and commercialisation of an indigenous 32-slice Computed Tomography (CT) scanner.
The project focuses on developing diagnostic imaging equipment in India. It is linked to efforts to strengthen domestic medical-device manufacturing and expand the country's capacity to develop advanced healthcare technologies.
How does a CT scanner work?
A CT scanner uses rotating X-ray systems and digital detectors to collect images from different angles. A computer processes these measurements to reconstruct cross-sectional images of internal body structures.
Doctors use CT imaging in different clinical settings to examine organs, bones and other internal structures. Accurate image reconstruction, equipment calibration and patient-safety controls are essential to its operation.
Why is indigenous development relevant?
- It can strengthen domestic capabilities in advanced medical-device manufacturing.
- It supports the development of Indian diagnostic imaging technologies.
- It may help reduce dependence on imported equipment over time, depending on manufacturing capacity and market adoption.
- It supports the wider objective of developing high-technology products under the Make in India initiative.
The announcement concerns support for development and commercialisation. It should not be interpreted as confirmation that the scanner has already completed all validation requirements or entered widespread clinical use.
Exam Point: CT stands for Computed Tomography. The agreement involves the Technology Development Board, DST and Panacea Medical Technologies Private Limited.
