2. Aditya-L1 and Proba-3: Advancing the Study of Solar Eruptions

1. Why in the News?

On 15 October 2026, the Indian Space Research Organisation (ISRO) reported that observations of the same coronal mass ejections (CMEs) by India's Aditya-L1 mission and the European Space Agency's Proba-3 mission had been jointly analysed. The study was published in the journal Astronomy & Astrophysics. Scientists from the Indian Institute of Astrophysics (IIA), Bengaluru, played an important role in the research.

The findings are significant for understanding solar eruptions and improving the scientific assessment of space weather.

2. What Is a Coronal Mass Ejection (CME)?

A Coronal Mass Ejection is an event in which the Sun releases a large amount of plasma and magnetic field into space from its outer atmosphere.

When a CME interacts with Earth's space environment, it can have several consequences:

• Disruption of satellite operations.
• Interference with radio communication and navigation systems.
• Induced currents in electrical power grids.
• Increased radiation-related risks for astronauts and spacecraft.

3. Role of the Two Missions

India's first dedicated solar mission was launched on 2 September 2023 and placed in a halo orbit around the Sun–Earth L1 point on 6 January 2024.

Its Visible Emission Line Coronagraph (VELC) studies the solar corona through spectroscopic observations.

This European Space Agency mission was launched on 5 December 2024 aboard India's PSLV-XL rocket.

Its two spacecraft fly in precise formation, approximately 150 metres apart. One spacecraft blocks direct sunlight from the other, creating an artificial-eclipse-like configuration. Its ASPIICS instrument observes the solar corona.

4. Major Findings of the Joint Study

According to ISRO, the instruments made observations of two CMEs between July and December 2025, which were subsequently analysed in detail.

• The CME observed on 14 September 2025 had an estimated speed of approximately 645 km per second.
• The CME observed on 16 September 2025 had an estimated speed of approximately 145 km per second.
• The mass and thermal-energy estimates obtained from the two instruments showed good agreement.
• Combining the observations helped researchers better understand the mass, density, energy and early development of CMEs close to the Sun.

5. Significance of the Achievement

Scientific significance: The early development of CMEs close to the Sun is difficult to observe. Combining data from two different instruments provides scientists with a more comprehensive understanding of these events.

Space-weather forecasting: Better knowledge of CME speed and energy can help scientists assess the potential effects of solar eruptions on Earth and space-based infrastructure.

Under the reported directions, the relevant industrial units are required to install and operationalise Pan-Tilt-Zoom (PTZ) cameras by 30 November 2026.

The measure aims to improve monitoring of industrial emissions, fuel use and compliance with pollution-control requirements.

2. What Is a PTZ Camera?

PTZ stands for Pan-Tilt-Zoom.

• Pan: Moving the camera horizontally.
• Tilt: Moving the camera vertically.
• Zoom: Magnifying an area or activity for closer observation.

These cameras allow authorities to monitor different parts of industrial facilities remotely. They can help identify suspicious activities, monitor compliance and support regulatory inspections.

3. Which Industries Are Covered?

According to the reported CAQM directions of 16 October, the requirements cover the following categories:

1. All 17 categories of highly polluting industries identified by the Central Pollution Control Board (CPCB).
2. Medium and large red-category air-polluting industries.
3. Food and food-processing industries equipped with boilers or thermic fluid heaters.
4. Textile industries equipped with boilers or thermic fluid heaters.
5. Metal industries equipped with furnaces.

The relevant industrial units must ensure installation and operation of the cameras within the prescribed deadline.

4. Objectives of the Monitoring System

5. Delimitation: Political Representation and the Challenge of Federal Balance in India

1. Why in the News?

On 17 October 2026, Mallikarjun Kharge, the Leader of the Opposition in the Rajya Sabha, wrote to Prime Minister Narendra Modi seeking an all-party meeting to discuss important parliamentary issues, including potential legislative initiatives related to delimitation. The demand highlights the need for broader political consultation on the issue.

Delimitation is significant because it concerns representation in Parliament and State Legislative Assemblies, population distribution and India's federal balance.

2. What Is Delimitation?

Delimitation refers to the redrawing of electoral constituency boundaries. Its objective is to maintain an appropriate balance of population and representation across constituencies.

There are two important aspects of delimitation in India:

• Redrawing constituency boundaries: Changing the boundaries of Lok Sabha or Assembly constituencies within a state.
• Reallocation of seats among states: Changing the number of Lok Sabha seats allocated to different states.

These aspects are related but involve distinct constitutional questions.

3. Constitutional Basis of Delimitation

Delimitation is carried out through statutory bodies such as the Delimitation Commission. The Commission's composition, functions and powers are determined by the relevant legislation.

4. Why Is Delimitation After 2026 Important?

The 84th Constitutional Amendment Act, 2001, extended the freeze on readjustment of the allocation of Lok Sabha seats among states and the total number of seats in State Legislative Assemblies until the relevant figures of the first census taken after 2026 are published. The applicable constitutional provisions provide for readjustment in accordance with the prescribed process.

This does not mean that seats will automatically be redistributed immediately after 2026. Any readjustment must follow the applicable constitutional provisions, the relevant census figures and the required legal procedure.

5. Major Issues Associated with Delimitation

(a) Population versus performance

If the allocation of Lok Sabha seats among states is revised on the basis of population, states with larger populations may gain representation.

At the same time, some states have achieved significant progress in population stabilisation, education and healthcare. These states may be concerned that population-based redistribution could reduce their relative political influence.

(b) North–South representation

Several northern Indian states have experienced substantial population growth, while many southern states have achieved lower fertility rates.

Consequently, the possibility of redistributing parliamentary seats raises questions about regional representation and political balance.

However, the actual impact cannot be determined without the relevant census data and the final constitutional and legal framework.

(c) Federalism

India's federal structure depends on the participation of states in national decision-making. Maintaining an appropriate balance between population-based representation and the political interests of different states is a major policy challenge.

(d) Link with Women's Reservation

The Constitution (106th Amendment) Act, 2023, provides for one-third reservation for women in the Lok Sabha and State Legislative Assemblies, subject to the prescribed census and delimitation-related conditions.

Consequently, the timing and process of delimitation may also affect the implementation of women's reservation.

6. Role of the Delimitation Commission

The Delimitation Commission is responsible for determining or redetermining electoral constituency boundaries in accordance with the relevant law.

Its major functions include:

• Addressing population disparities among constituencies.
• Determining reserved constituencies for Scheduled Castes and Scheduled Tribes.
• Considering geographical and administrative factors while defining constituency boundaries.
• Improving the fairness and practical functioning of electoral representation.

The legal status of the Commission's orders is governed by the relevant legislation. Its decisions should not be treated as ordinary administrative orders.

7. Way Forward

Delimitation requires a broad constitutional and federal perspective rather than an exclusive focus on changes in population.

The following measures may help:

1. Transparent consultation with political parties and state governments.
2. Public analysis of census data and the likely effects of proposed changes.
3. Clear discussion of regional representation and federal balance.
4. Assessment of the implications for women's representation and reservations for Scheduled Castes and Scheduled Tribes.
5. Strict adherence to constitutional procedures and democratic consensus.

8. UPSC/UPPCS Examination Relevance

• Prelims: Articles 81, 82, 170 and 327; Delimitation Commission; constitutional amendments.
• Mains GS-II: Federalism, Parliament, electoral reforms, political representation and women's reservation.
• Essay: Equal representation and federal balance in a democracy.

Conclusion: Delimitation is not merely an exercise in redrawing electoral boundaries. It is a constitutional question involving political representation, population, federalism and democratic equality. Its success will depend on a transparent process, reliable data and broad political consensus.
