1. ISRO Launches NVS-03: A Fresh Lease of Life for NavIC
Why in news: ISRO's GSLV-F18 placed the navigation satellite NVS-03 into orbit at 11:51 pm IST on 30 October 2026 from Sriharikota. The launch restores the positioning, navigation and timing (PNT) services of NavIC, India's own satellite navigation system.
Background: why NVS-03 matters
NavIC (Navigation with Indian Constellation), formerly IRNSS, was hit by failing imported atomic clocks in its first-generation satellites. The second-generation NVS series (NVS-01 to NVS-05) was planned to keep the service running with better features.
NVS-01 flew in May 2023 with India's first indigenous atomic clock. NVS-02, launched on 29 January 2025 as the 100th launch from Sriharikota, was left stranded in transfer orbit after its oxidiser valves failed to open. NVS-03 therefore became critical for continuity.

2. Industrial Growth Slows to a Four-Month Low of 6.7% in September
Why in news: Data released on 29 October 2026 show India's Index of Industrial Production (IIP) grew 6.7% year-on-year in September 2026, the slowest pace in four months. August's growth was revised down to 7.8% from the earlier estimate of 8%.
Sector-wise performance
| Sector | Weight in IIP | September 2026 | August 2026 |
|---|---|---|---|
| Manufacturing | About 76% | 7.6% | 8.6% |
| Electricity and gas supply | - | 11.2% | 12.3% (27-month high) |
| Water supply, sewerage and waste management | - | 5.8% | 6.3% |
| Mining and quarrying | - | Contracted 6.2% | - |
| Overall IIP | 100% | 6.7% | 7.8% (revised) |
What pulled growth down
- Mining contraction: Mining shrank 6.2%, its steepest fall since September 2023, and was the main drag.
- Softer manufacturing: Still strong at 7.6%, but the slowest in four months.
- Base effect: Growth had picked up sharply in September 2025, making the comparison tougher this year.
Use-based classification highlights
- Primary goods eased to 4.0% from 4.2% in August.
- Consumer durables posted their weakest growth in five months.
- Consumer non-durables returned to growth after two months of decline.
- Automobiles and electrical machinery led manufacturing growth.

- Periodicity: Monthly quick estimates, released with a lag of about four weeks.
- Real measure: IIP tracks volume of output, not value.
- Related index: The Index of Eight Core Industries (by DPIIT) covers the core sectors that carry a large share of IIP weight.
UPSC relevance
- Prelims: IIP base year, publishing agency, sector weights, IIP vs core sector index.
- Mains (GS-III): Industrial growth, manufacturing, mining sector, economic indicators.
Mains practice question: Despite robust manufacturing growth, mining continues to weigh on India's industrial output. Examine the structural reasons and suggest reforms. (150 words)
3. Over 1,200 Blackbucks and Nilgai Rescued in Shajapur: Project Antelope Translocation
Why in news: Madhya Pradesh Chief Minister Mohan Yadav reviewed the second phase of a wildlife rescue drive at Ranthbhanwar village in Shajapur district on 28 October 2026. More than 1,236 blackbucks and nilgai had been safely captured and relocated by then, in what the state called the first operation of its kind in South Asia.
Why the operation was needed
Large herds of blackbuck and nilgai (blue bull) damage standing crops across the Malwa region, creating human-wildlife conflict. Instead of culling, the state chose to translocate the animals to forests and protected areas. The drive is part of the state's Kisan Kalyan Varsh (Farmers' Welfare Year).
Key facts at a glance
| Parameter | Detail |
|---|---|
| Programme | Project Antelope Translocation |
| Location | Shajapur district, Madhya Pradesh |
| Phase 2 dates | 9 to 31 October 2026 |
| Target | 2,000 blackbucks |
| Rescued so far | More than 1,236 animals |
| Technique | Boma method with helicopter support |
| Technical partner | Specialist team from South Africa |
| Relocation sites | Kuno National Park (Sheopur), Gandhi Sagar Wildlife Sanctuary, Rani Durgavati Tiger Reserve |
| Transport | Fleet of 11 trucks |
| Next phase | Nilgai rescue in Ujjain district |
What is the Boma technique?
Boma is an African wildlife capture method. A funnel-shaped enclosure of opaque screens is built, and animals are gently herded into it, here with a helicopter. The funnel narrows into a holding pen and then a transport vehicle. Because animals cannot see out, stress and injury are far lower than with chasing or darting.
Species profile for Prelims
| Feature | Blackbuck | Nilgai |
|---|---|---|
| Scientific name | Antilope cervicapra | Boselaphus tragocamelus |
| IUCN status | Least Concern | Least Concern |
| Wildlife (Protection) Act, 1972 | Schedule I | Protected species |
| Habitat | Open grasslands, dry scrub | Scrub forest, grassland, farmland edges |
| Notable fact | State animal of Punjab, Haryana and Andhra Pradesh; revered by the Bishnoi community | Largest antelope in Asia |
UPSC relevance
- Prelims: Species status, Boma technique, protected areas of Madhya Pradesh (Kuno, Gandhi Sagar, Rani Durgavati).
- Mains (GS-III): Human-wildlife conflict, conservation versus farmer livelihoods, translocation as a management tool.
Mains practice question: Translocation is often presented as a humane solution to human-wildlife conflict. Critically evaluate its effectiveness with reference to recent initiatives in Madhya Pradesh. (150 words)

5. How El Nino Shaped the Path and Intensity of Cyclone Arnab
Why in news: Very Severe Cyclonic Storm Arnab, the first cyclone of the 2026 North Indian Ocean season, crossed the Andhra Pradesh and Yanam coast on 28 October 2026. Its rapid intensification, unusually southern track and refusal to weaken after landfall have put the spotlight on a strengthening El Nino.
Life cycle of Cyclone Arnab
- 23 October: Low-pressure area forms over the southeast Bay of Bengal.
- 24 October: Becomes a depression.
- 26 October: Intensifies into a cyclonic storm and is named Arnab; within about a day it becomes a Very Severe Cyclonic Storm (VSCS).
- 28 October: Landfall between Narsapur and Yanam, about 20 km east-northeast of Narsapur, with sustained winds of 125-135 km/h gusting to 150 km/h. The crossing took more than six hours.
- After landfall: Holds its intensity for about six hours before weakening into a severe cyclonic storm, then a deep depression over Odisha.
- 29 October: Dissipates.
Key facts at a glance
| Parameter | Detail |
|---|---|
| Category at landfall | Very Severe Cyclonic Storm |
| Basin | Bay of Bengal, North Indian Ocean |
| Name given by | Bangladesh |
| Landfall | Andhra Pradesh and Yanam (Puducherry) coast, near Narsapur |
| Wind speed at landfall | 125-135 km/h, gusts up to 150 km/h |
| Evacuations | More than 1.8 lakh people in Andhra Pradesh and Odisha |
| Unusual features | Rapid intensification, stalled landfall, intensity held for about 6 hours on land |
How El Nino shaped Arnab
- Southward track: Post-monsoon Bay of Bengal storms usually recurve north towards Odisha and West Bengal. In El Nino years, cyclones tend to form at lower latitudes and strike further south, towards Andhra Pradesh and Tamil Nadu.
- Changed steering winds: El Nino alters wind and pressure patterns, which shifted the steering currents and pushed Arnab towards the coast faster than first forecast.
- High ocean heat content: Warm water of 26 degrees C or more extending to about 100 m depth acted as fuel, enabling rapid intensification.
- Favourable upper atmosphere: Low vertical wind shear and a compact core let the storm organise quickly and persist after landfall.
Caution for answer writing: El Nino is a background driver, not the sole cause. Local factors such as sea surface temperature, wind shear and moisture decide the behaviour of an individual cyclone.
Static concepts for Prelims
- El Nino: Abnormal warming of the central and eastern equatorial Pacific; part of the El Nino-Southern Oscillation (ENSO), tracked in the Nino 3.4 region. It usually weakens the Indian monsoon.
- IMD classification: Depression (31-49 km/h), Cyclonic Storm (62-88), Severe (89-117), Very Severe (118-165), Extremely Severe (166-220), Super Cyclonic Storm (221 and above).
- Rapid intensification: An increase of at least 30 knots (about 55 km/h) in maximum sustained winds within 24 hours.
- Naming: Names come from a list prepared by the 13 member countries of the WMO/ESCAP Panel on Tropical Cyclones; IMD's Regional Specialised Meteorological Centre in New Delhi assigns them.
- Why landfall weakens cyclones: Loss of moisture supply and greater surface friction.
UPSC relevance
- Prelims: ENSO, cyclone categories, naming system, rapid intensification, Yanam's location.
- Mains (GS-I and GS-III): Climate drivers of cyclones, disaster management, forecasting challenges.
Mains practice question: Explain how El Nino influences the frequency, track and intensity of tropical cyclones in the Bay of Bengal. Illustrate with the example of Cyclone Arnab. (250 words)
