About SSLV:

• The SSLV is a three-stage rocket equipped with solid propulsion stages and a liquid-based Velocity Trimming Module (VTM) for precise satellite placement.
• The primary aim behind the development of SSLVs is to provide a low-cost, rapid-turnaround solution for launching smaller satellites.
• Unlike previous launch vehicles that required extensive preparation and scheduling, the SSLV can be integrated within 72 hours—a dramatic reduction from the 70 days typically needed for other vehicles.
• This efficiency also translates into a significant cost reduction, with the SSLV projected to cost around Rs 30 crore.
• It can carry payloads of up to 500 kg, accommodating the growing demand from businesses, government agencies, universities, and laboratories for timely and flexible satellite launches.
• Before the SSLV, smaller payloads were launched as secondary payloads on larger rockets, often leading to delays due to the primary payload’s schedule.
• Former ISRO Chairman K. Sivan highlighted that the SSLV’s design requires only six people for integration, compared to 60 for other launch vehicles, further underscoring its streamlined approach.
• In contrast, ISRO’s Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV) serve different needs.

• The PSLV, often termed as ISRO’s “workhorse,” has been in operation since 1994 and is renowned for its reliability in placing satellites into low Earth orbit, carrying up to 1,860 kg of payload.
• On the other hand, the GSLV is designed for launching heavier satellites into geosynchronous transfer orbits, with its higher capacity derived from advanced cryogenic engines that provide greater thrust.
• The GSLV Mk-II can carry up to 2,200 kg, while the Mk-III can handle payloads up to 4,000 kg. These vehicles are crucial for missions requiring more power and capacity, demonstrating the diverse capabilities of ISRO’s launch vehicle portfolio.Top of Form

Additional Information:

About Mpox Virus:

• Mpox, formerly known as monkeypox, is a rare zoonotic disease caused by the monkeypox virus from the Orthopoxvirus genus, related to smallpox, cowpox, and vaccinia.
• History: The virus was first identified in Denmark in 1958 and the first human case was reported in the Democratic Republic of the Congo (DRC) in 1970.
• Transmitted by: Mpox spreads from animals (primarily rodents and primates)  to humans through direct contact or contaminated objects, and from person to person via direct contact with body fluids, sexual contact, or contaminated materials.
• Two genetic clades exist: clade I, prevalent in central and east Africa, and clade II, mostly found in west Africa.
• Recently, the new Ib clade of the virus has been observed to spread more effectively through human-to-human transmission, particularly via close contact and sexual routes and is significantly more lethal than other variants that primarily spread from animals.

• Symptoms:
• Include rashes that develop into itchy or painful blisters, fever, sore throat, headache, muscle aches, back pain, low energy, and swollen lymph nodes.
• Symptoms generally appear within a week of infection but can take 1–21 days to manifest and last 2–4 weeks.
• Severe cases may require medical care, especially for children, pregnant women, and immunocompromised individuals.
• Treatment:
• There is no specific treatment for mpox. WHO advises supportive care, including pain and fever management, hydration, and skin care.
• An antiviral, tecovirimat, used for smallpox, is available under exceptional circumstances but has limited experience.
• Vaccines developed for smallpox—MVA-BN, LC16, and OrthopoxVac—are approved for high-risk individuals, though mass vaccination is not recommended.

Great Calcutta Killings

GS 1: Culture and history: Communal Violence

About the news

• Between August 16 and August 19, 1946, Calcutta (now Kolkata) experienced one of the worst episodes of communal violence in its history, known as the ‘Great Calcutta Killings’.
• This tragic event resulted in the deaths of an estimated 5,000 to 10,000 people, with around 15,000 wounded. The violence unfolded as part of the broader turmoil leading up to India’s independence and partition.
• The immediate trigger for this bloodbath was Muhammad Ali Jinnah’s call for ‘direct action’ on August 16, 1946, after the failure of the Cabinet Mission Plan.
• ‘Direct Action Day’ initiated a series of violent incidents over several days, known as the ‘Week of the Long Knives’.
• The plan had proposed a federal structure for post-colonial India, but its collapse deepened the rift between the Muslim League and the Indian National Congress.
• Jinnah’s call was intended to rally support for the League’s resolution for a separate Muslim state, but it led to widespread violence, particularly in Calcutta. The city’s political context further exacerbated the violence.
• While Muslims were a majority in Bengal, they were largely concentrated in rural areas, with Calcutta itself being predominantly Hindu. Tensions between the communities had been rising for years, with periodic instances of communal strife.
• Huseyn Suhrawardy, the Chief Minister of Bengal at the time, played a controversial role. Known for his inflammatory rhetoric and previous mismanagement during the Bengal famine of 1943, Suhrawardy’s actions during the riots are widely criticized.
• Historians argue that his public statements and actions—or lack thereof—contributed significantly to the escalation of violence. Suhrawardy reportedly failed to control the riots effectively and allowed the violence to escalate.
• The Great Calcutta Killings were marked by extreme brutality, with reports of grotesque mutilations and the use of rape as a weapon of terror. The scale and savagery of the violence were unprecedented, setting a grim precedent for the communal horrors that would follow during the partition of India.
• The event remains a poignant reminder of the intense communal tensions that plagued the subcontinent in the run-up to independence.

Background: What caused this situation?

Cabinet Mission,1946

• In 1946, as the Indian independence movement neared a critical juncture, British Prime Minister Clement Attlee sent a three-member Cabinet Mission to India to discuss and finalize the transfer of power from the British Raj to Indian leaders.
• It had three British cabinet members: Penthick Lawrence (Chairman), Secretary of State for India; Stafford Cripps, President of the Board of Trade; and A.V. Alexander, First Lord of Admiralty

Salient Features of the Cabinet Mission Plan:

• In 1946, the Cabinet Mission arrived in India and held talks with leaders of all major political parties, proposing the establishment of a Federal Government.
• It rejected the demand for Pakistan and instead suggested an Indian Union comprising British provinces and Princely States.
• The plan introduced the concept of grouping, allowing provinces and princely states to form autonomous groups under the Union.
• An Interim Government was to be formed from the Constituent Assembly.
• Muhammad Ali Jinnah, leader of the Muslim League, had initially accepted the Cabinet Mission Plan of June 16, which was also agreed upon by the central presidium of the Congress.
• However, on July 10, Congress President Jawaharlal Nehru announced that while the Congress would participate in the Constituent Assembly, it reserved the right to modify the plan.
• This led to concerns among Muslim League leaders about potential Hindu dominance in the central government, prompting Jinnah to abandon his previous acceptance and reject the plan.
• Subsequently, Jinnah called for a boycott of the Constituent Assembly and declared August 16, 1946, as “Direct Action Day,” signalling the beginning of a planned struggle by the Muslim League to press for Pakistan.

Land related reforms in Rural and Urban Areas

GS 3: Economy: Land Reforms

Why is it in the news?

• The Centre has allocated ₹10,000 crore in incentives to states for implementing land-related reforms in both rural and urban areas and ₹5,000 crore for creating a Farmers’ Registry for the financial year 2024-25.
• These funds will be provided under the Scheme for Special Assistance to States for Capital Investment 2024-25.

More about the news

• In rural areas, states are required to implement several key reforms, including the assignment of a Unique Land Parcel Identification Number (ULPIN or Bhu-Aadhaar) for all lands, digitization of cadastral maps, and the survey of map sub-divisions according to current ownership and the establishment of a comprehensive land registry.
• For urban areas, fiscal incentives will support the digitization of land records using Geographic Information System (GIS) mapping and the creation of an IT-based system for property record administration, updating, and tax management.
• An additional ₹5,000 crore will be allocated to develop a Farmers’ Registry, which will encompass details of six crore farmers and their lands.

About Unique Land Parcel Identification Number (ULPIN): Unique Land Parcel Identification Number (ULPIN) also known as ‘Bhu-Aadhaar’ launched in 2008, is a unique 14-digit identifier assigned to each land parcel in India. This is the next step of the Digital India Land Records Modernisation Programme (DILRMP), which started in 2008.This initiative, part of a broader digitization drive, aims to standardize land parcel identification and enhance land management and governance across the country.The identification will be based on the longitude and latitude coordinates of the land parcel, and is dependent on detailed surveys and geo-referenced cadastral maps.Key aspects of ULPIN include: GIS Mapping: The ULPIN initiative utilizes Geographic Information System (GIS) technology to ensure accurate mapping and updating of land records.Integration with Land Registry: ULPIN will seamlessly integrate with existing land registries to accurately record all land parcels and keep ownership details up-to-date.Curbing Malpractices: The ULPIN implementation and digitization of land records can greatly diminish unethical and illegal land activities by enhancing transparency and accountability.Digitization of Land Records: ULPIN is a key component of the digitization drive designed to make land records easily accessible, safeguarding them from loss during calamities like floods and fires, and accelerating the recovery process.Efficient Land Use: ULPIN will enhance the management of land parcels and support the development and execution of new schemes.
