• Bali Jatra 2024 is being held from November 15 to November 22 in Cuttack, Odisha.
• The festival celebrates Odisha’s ancient maritime history and its cultural and trade links with Southeast Asia.
• The event has gained international attention due to the participation of diplomats and cultural troupes from ASEAN, BIMSTEC, and Pacific Island countries.

Historical and Cultural Significance:

• Bali Jatra ("Voyage to Bali") commemorates the 2,000-year-old maritime trade routes between ancient Kalinga (modern-day Odisha) and Southeast Asia, including regions like Bali, Java, Sumatra, Borneo, Burma (Myanmar), and Sri Lanka.
• The festival honors the skills of Kalinga sailors who contributed to the prosperity of the region through trade, including commodities like pepper, cinnamon, cardamom, silk, camphor, gold, and jewelry.
• It highlights Odisha’s maritime legacy and the cultural exchanges between India and Southeast Asia, particularly the cultural influence of Odia merchants on Bali.

Commercial and Economic Aspects:

• Bali Jatra is Asia’s largest open-air trade fair, featuring over 2,500 stalls selling a variety of products including artisanal crafts, household items, and food.
• The event is a major commercial activity with business transactions estimated to exceed ?100 crore over the course of the festival.
• The festival provides an opportunity for both local and national traders to exhibit products at competitive prices.

Cultural Performances and International Participation:

• The festival includes daily cultural performances showcasing Odissi dance, Chhau dance, Bihu, Mahari, Gotipua, Sambalpuri, and Santali folk dances.
• This year, cultural troupes from countries like Indonesia, Thailand, and Sri Lanka have participated, enhancing the international profile of the festival.
• Diplomats, including Ambassadors, High Commissioners, and Heads of Mission from 14 countries attended the inaugural ceremony.

Historical Background of Bali Jatra:

• The festival is linked to Kartika Purnima, the full moon night of the month of Kartika, marking the annual migration of traders from Odisha to Southeast Asia.
• Traders used boats called Boitas to travel to distant lands, which is now symbolically represented in the festival.
• The event’s cultural significance extends to the recognition of Odisha’s historic maritime routes, with ports like Tamralipti, Manikpatna, Chelitalo, Palur, and Pithunda playing key roles in global trade from as early as the 4th century BC.

Kalinga's Maritime Influence:

• The Kalinga Empire (present-day Odisha) had significant influence over the Bay of Bengal, referred to as the Kalinga Sea.
• Kalinga’s dominance in maritime trade is reflected in Kalidasa's Raghuvamsa, where the King of Kalinga is called "Lord of the Sea."
• Kalinga's Boitas (ships) were instrumental in connecting India with the Southeast Asian archipelago, including Bali.

Cultural Linkages with Bali:

• Odisha's trade with Bali influenced the culture, religion, and architecture of the region.
• Balinese Hinduism today still reflects Indian influences, with worship of Hindu deities like Shiva, Vishnu, Brahma, and Ganesha.
• The MasakapankeTukad festival in Bali, similar to Bali Jatra in Odisha, is a tribute to the maritime ancestors of Bali and commemorates the long-standing cultural ties.

Recognition and Milestones:

• Bali Jatra 2022 achieved a Guinness World Record for creating the largest collection of origami sculptures.
• The festival has evolved from a traditional trade fair to an international cultural event that highlights Odisha’s historical role in global trade and cultural exchanges.

Chinese rover helps find evidence of ancient Martian shoreline.

Mission Overview:

• Rover: Zhurong, part of China’s Tianwen-1 Mars exploration program.
• Mission Launch: Zhurong landed in 2021 in the Utopia Planitia region of Mars' northern hemisphere.
• Key Discovery: Evidence of an ancient ocean on Mars, suggesting a habitable past for the planet.

Key Findings:

• Geological Features Indicating a Coastline:
  • Data from Zhurong and orbiting spacecraft (Tianwen-1 Orbiter, NASA's Mars Reconnaissance Orbiter) revealed geological features such as troughs, sediment channels, and mud volcano formations, suggesting the existence of a Martian coastline.
  • Features indicate both shallow and deeper marine environments, supporting the idea of a past ocean.
• Age of the Ocean:
  • The ocean likely existed around 3.68 billion years ago, with its surface potentially frozen in a geologically short period.
  • The ocean is thought to have disappeared by 3.42 billion years ago.

Evolutionary Scenario of Mars:

• At the time of the ocean, Mars might have already begun transitioning away from a habitable planet, losing much of its atmosphere and becoming cold and dry.
• The ocean may have formed after Mars' climate began to change, suggesting that it was once more hospitable, possibly capable of supporting microbial life.

Implications for Life on Mars:

• The presence of water, a key ingredient for life, raises the possibility that Mars could have supported microbial life in its early history.
• When Mars had a thick, warm atmosphere, conditions might have been favorable for life, as microbial life would have been more likely to exist.

Significance of Zhurong's Contribution:

• Zhurong exceeded its original mission duration of three months, operating until May 2022, helping provide key data to understand Mars' ancient water history.
• The discovery adds to ongoing efforts to study the disappearance of water on Mars and its implications for the planet's habitability.

Future Exploration:

• Other studies, including seismic data from NASA’s InSight lander, suggest that liquid water might still exist deep beneath the Martian surface, hinting at the possibility of finding water in the planet's subsurface in the future.

Israeli researchers from the Israel Institute of Technology have developed the PyPIM platform, which allows computers to process data directly in memory, eliminating the need for a central processing unit (CPU). This breakthrough aims to address key challenges in modern computing, particularly in terms of energy consumption and processing efficiency.

Key Features of the PyPIM Platform:

• Integration with Python and PIM Technology:
  • The PyPIM platform merges Python programming with digital processing-in-memory (PIM) technology, facilitating in-memory computing where computations occur directly within memory instead of transferring data to and from the CPU.
• Functionality and Innovations:
  • Direct In-Memory Computations: PyPIM uses specialized instructions that enable computations to take place directly in memory, reducing the need for data movement between the CPU and memory.
  • Developer-Friendly: It allows developers to use familiar languages like Python to write software for in-memory computing systems.
• Solving the "Memory Wall" Issue:
  • The platform addresses the memory wall problem, where the speed of the CPU and memory exceeds the data transfer rates, creating bottlenecks that lead to inefficiencies.
  • By performing calculations directly in memory, PyPIM reduces time and energy spent on data transfer, optimizing performance.
• Performance Improvements:
  • Energy and Time Efficiency: By minimizing energy-intensive data transfers, PyPIM leads to significant energy and time savings.
  • Simulation Tools: The platform includes tools that allow developers to simulate potential performance improvements from in-memory processing.
• Real-World Benefits:
  • Faster Processing: Tasks performed using PyPIM have demonstrated faster processing speeds, with minimal code changes, particularly in mathematical and algorithmic tasks.
  • The platform delivers a significant performance boost in areas like data analysis and algorithmic operations.

The PyPIM platform marks a pivotal advancement in computing architecture, providing a more energy-efficient and faster alternative to traditional CPU-dependent systems by reducing reliance on external memory processing and cutting down on data transfer delays.
