Gujarat to Get Country's 1st 'Satellite Network Portal Site'

Gujarat will get the country's first 'Satellite Network Portal Site'. An MoU was signed between OneWeb and the state government in Gandhinagar for the establishment of the satellite network portal site near Mehsana. The satellite network portal will be set up at two places in Jotana taluka of Mehsana district, Gujarat with an estimated cost of over Rs. 100 crore for Phase-1. This project under Digital India, aims to provide affordable, secure and high speed internet access to villages, district panchayats, local administrative bodies, government departments, and other entities throughout the country.

ISRO Prepares for a PSLV Mission

After the spectacular start to the Chandrayaan-3 moon mission, scientists at the Indian Space Research Organisation (ISRO) were back in Sriharikota for another important launch later this month.
The Polar Satellite Launch Vehicle, C56 (PSLV-C56) mission is expected to lift off from the Satish Dhawan Space Centre towards July-end, July 26 as per the latest updates.
ISRO will be using a 'core alone' variant of the PSLV for this mission, S. Unnikrishnan Nair, Director of the Vikram Sarabhai Space Centre (VSSC), ISRO's lead facility for launch vehicles said.
The PSLV-C56 will have seven payloads in all including the 351.9 kg earth observation satellite DS-SAR (short for Synthetic Aperture Radar) from Singapore. The others are Arcade (23.58 kg), Velox-AM (23 kg) and Orb-12 Strider (12.8 kg). The remaining three are nanosatellites weighing less than 10 kg each. They are the Galassia-2 (3.84 kg), SCOOB-II (4.1 kg) and NuLIon (3.05 kg), according to a list provided by the VSSC. These satellites will be placed in a Low Earth Orbit (LEO).

NASA: Sixty Two of 111 Lunar Missions in Last Seven Decades were Successful

According to the US space agency NASA's database on Moon missions Of the 111 lunar missions, in the last seven decades, 62 were successful, 41 failed and eight achieved partial success.
India launched its third mission to the Moon, Chandrayaan-3, with an aim to soft land on the surface of Earth's only natural satellite. A successful landing would make India the fourth country to achieve the rare feat after the United States, China and the erstwhile USSR.
According to the Indian Space Research Organisation (ISRO), the technically challenging soft landing on the lunar surface, which Chandrayaan-2 could not achieve, has been planned for 5.47 pm on August 23.
From 1958 to 2023, India as well as the US, the USSR (now Russia), Japan, the European Union, China and Israel have launched different lunar missions – from orbiters, landers and flyby (orbiting the Moon, landing on the Moon and flying by the Moon).

India Launches Historic Chandrayaan-3 Mission

India is bidding to become only the fourth country to execute a controlled landing on the moon with the successful launch of its Chandrayaan-3 mission.
Chandrayaan, which means "moon vehicle" in Sanskrit, blasted off from the Satish Dhawan Space Center at Sriharikota in southern Andhra Pradesh.
It iss India's second attempt at a soft landing, after its previous effort with the Chandrayaan-2 in 2019 failed. Its first lunar probe, the Chandrayaan-1, orbited the moon and was then deliberately crash-landed onto the lunar surface in 2008.
Developed by the Indian Space Research Organization (ISRO), Chandrayaan-3 is comprised of a lander, propulsion module and rover. Its aim is to safely land on the lunar surface, collect data and conduct a series of scientific experiments to learn more about the moon's composition.
Only three other countries have achieved the complicated feat of soft-landing a spacecraft on the moon's surface – the United States, Russia and China.

Elon Musk Launches Artificial Intelligence Firm xAI

Elon Musk, CEO of Tesla and SpaceX, and owner of Twitter, announced the debut of a new artificial intelligence company, xAI, with the goal to understand the true nature of the universe.
Team members behind xAI are alumni of DeepMind, OpenAI, Google Research, Microsoft Research, Twitter and Tesla, and have worked on projects including DeepMind's AlphaCode and OpenAI's GPT-3.5 and GPT-4 chatbots. Musk seems to be positioning xAI to compete with companies like OpenAI, Google and Anthropic, which are behind leading chatbots like ChatGPT, Bard and Claude.
According to Greg Yang, co-founder of xAI, the start-up will delve into the mathematics of deep learning, a facet of AI, and develop the theory of everything for large neural networks to take AI to the next level.
