Clean Energy Expo Organised in Greater Noida

The 18th Renewable Energy India (REI) Expo and the 3rd Battery Show India (TBSI) is being held together from October 30 to November 1 at the India Expo Mart, Greater Noida. Organised by Informa Markets in India, the event brings together global and Indian stakeholders in renewable energy under the theme 'Decoding Pathways to Achieve Net Zero'.
The co-located expos are hosting over 1,050 exhibitors and expect around 55,000 visitors, including industry leaders, policymakers, and innovators from countries such as China, Japan, Korea, Germany, and Belgium. The Government of Odisha has joined as a State Partner, while institutional support comes from the Department of Science & Technology, the Ministry of Heavy Industries, and the Ministry of New and Renewable Energy.

Stellerus to Launch First 3D Wind Data Satellite Network

In a pioneering move for climate and space technology, Hong Kong-based start-up Stellerus Technology announced plans to deploy the Feilian Constellation—the world's first satellite constellation dedicated to capturing three-dimensional wind data. This ambitious project, named after the ancient Chinese god of wind, is set to transform how the world observes atmospheric dynamics, with vast implications for renewable energy, aviation safety, disaster management, and insurance modelling.

NASA Confirms Discovery of 2025 PN7, Earth's Temporary Second Moon

Earth has a new space companion, a small asteroid named 2025 PN7, confirmed by NASA. Though it's not a real moon, it travels around the Sun in almost the same orbit as Earth, making it look like it's following our planet through space.
This 'quasi-moon', first discovered by astronomers at the University of Hawaii, is estimated to be 18 to 36 metres wide — about the height of a small building. While tiny by space standards, its discovery is fascinating for scientists studying how asteroids move near Earth.
The asteroid 2025 PN7 is not directly orbiting Earth like our natural moon. Instead, it travels around the Sun on a path that nearly matches Earth's. This unique movement makes it appear as if it's staying close to us, even though it's actually an independent traveler in space.
NASA scientists describe it as being like a friendly runner keeping pace on the same track — close enough to notice but never touching.

Japan Successfully Launches New Cargo Spacecraft

Japan's space agency successfully launched its most powerful flagship H3 rocket, carrying a newly developed unmanned cargo spacecraft for its first mission to deliver supplies to the International Space Station.
The HTV-X1 spacecraft successfully lifted off atop the No. 7 H3 rocket from Japan's Tanegashima Space Centre in the country's south and confirmed it entered targeted orbit 14 minutes after liftoff.
The HTV-X is the successor to JAXA's unmanned H-II Transfer Vehicle, known as Kounotori, or stork in Japanese, which flew nine missions to the ISS between 2009 and 2020.

Powering Next-Generation Technology

India has steadily advanced its indigenous semiconductor capabilities over the past decade, developing home-grown processor architectures, nurturing design talent, and strengthening research infrastructure. These efforts have built a strong foundation for the country's emergence as a key player in the global chip design ecosystem.
Building on this progress, India is now taking a major step forward with the development of a 7 nanometre processor, marking its entry into advanced node semiconductor design. The initiative signifies a defining moment in India's semiconductor journey and reaffirms the nation's commitment to self-reliant, next-generation technology innovation.
The 7 nm processor is being developed by the Indian Institute of Technology, Madras (IIT Madras), a key institution in India's processor design ecosystem through its SHAKTI initiative. Started in 2013, SHAKTI is based on open-source instruction set architecture, allowing anyone to adopt and use it freely without restrictions.
