The National Highways Authority of India (NHAI) has partnered with IIIT Delhi to utilize Artificial Intelligence (AI) to improve road sign availability and safety on National Highways. This collaboration involves leveraging AI technologies to survey, classify, and assess the condition of road signs across approximately 25,000 kilometres of National Highways, aiming to enhance safety standards through data-driven interventions.

Dhruva Space's Thybolt-1 and Thybolt-2 satellites were launched by ISRO's PSLV C54 in November 2022. These satellites completed 15,000 orbits around Earth as part of their mission, marking a significant achievement for the Hyderabad-based space tech startup in satellite technology and deployment.

The NISAR (NASA ISRO Synthetic Aperture Radar) satellite mission is a joint initiative between NASA and the Indian Space Research Organisation (ISRO). This collaboration aims to launch a powerful Earth-observing satellite that will utilize synthetic aperture radar technology to monitor and measure various changes on Earth's surface, including ice sheets, glaciers, wetlands, forests, and geological features. The partnership underscores NASA's role in advancing global climate change research and enhancing environmental monitoring capabilities through space-based missions.

Chinese scientists, using the Chinese H-alpha Solar Explorer (CHASE) satellite, made a breakthrough in solar research by identifying a new pattern of solar atmospheric rotation. Launched by the China National Space Administration (CNSA), the CHASE mission aims to enhance understanding of solar dynamics through spectroscopic observations in the H-alpha waveband, marking a significant achievement in China's space exploration efforts.

Chinese scientists utilized the CHASE (Chinese H-alpha Solar Explorer) satellite to identify a novel pattern in the rotational dynamics of the solar atmosphere. Launched in October 2021 with a planned operational span of three years, CHASE orbits Earth in a fixed position relative to the sun, enabling continuous observation of solar phenomena and contributing valuable insights into solar physics and atmospheric dynamics.
