Aditya-L1 could help India prepare for climate change: Ex-Isro chief Nair

With the successful launch of India's first solar mission Aditya-L1, the country could develop some prediction models and prepare a resilience plan to combat climate change, former ISRO chairman G Madhavan Nair said here on Saturday. Sharing his excitement shortly after the successful takeoff of PSLV-C57, carrying the Aditya satellite from Sriharikota, Nair said it is very important to study the solar surface to understand various phenomena that instantaneously affect our local weather conditions. "Long-term variability of solar radiation also is a very important factor in the study of climate change. So, in all these areas, fundamental knowledge will be acquired through this unique mission," Nair told PTI. He said from the expected final destination of the satellite, Lagrange Point 1 (L1), the satellite could observe the Sun round the clock and extract exact data regarding various solar phenomena. "We can only try to have some (prediction) models, and the models can be validated .

Ex-ISRO chief Rao's key role in Aditya-L1 mission's success recalled

With the successful launch of India's ambitious solar mission Aditya-L1, former ISRO chief Prof U R Rao's dream and contribution towards its realisation at the initial stages was fondly remembered. According to ISRO, Prof. Rao, affectionately called the father of India's satellite programme, was particularly excited about the Aditya mission and he ensured that it went through a thorough revamp of its mission objectives including its orbital parameters to make the expedition more meaningful and contemporary. Thanks to Prof. Rao, Aditya-L1 will become the first mission from India to be placed in the Lagrange Point, L1, one of the liberation points in orbital configuration situated 1.5 million kilometres from the Earth, where a satellite upon placing will have the same angular velocity as that of the Earth with respect to Sun and hence, maintain the same position in relation to the Sun as seen from Earth, a tribute to Prof. Rao on ISRO's website states. The launch of Aditya-L1 by ...

Chandrayaan-3 lander gauges first-ever measurements of near-surface plasma

The initial assessment of the first-ever measurements of the near-surface lunar plasma environment over the south pole region by RAMBHA-LP payload onboard Chandrayaan-3 lander indicates that plasma there is relatively sparse, ISRO said on Thursday. Meanwhile, the ILSA payload on Chandrayaan 3 lander to study lunar seismic activity has not only recorded the movements of rover and other payloads, but also has recorded an event, appearing to be a natural one, on August 26. The source of this event is under investigation, ISRO said. "Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere - Langmuir Probe (RAMBHA-LP) payload onboard Chandrayaan-3 Lander has made first-ever measurements of the near-surface Lunar plasma environment over the south polar region. The initial assessment indicates that the plasma near the lunar surface is relatively sparse, ISRO said in a social media post. These quantitative measurements potentially assist in mitigating the noise that Lunar plas

GalaxEye unveils drone-based high resolution all-weather imaging system

Space start-up GalaxEye has unveiled a high resolution aerial drone-based Synthetic Aperture Radar (SAR) system. The cutting edge system can perform exceptionally detailed and high resolution all-weather imaging, even amidst rainy or cloudy conditions, GalaxEye said in a statement here. The in-house developed data fusion technology will deliver unprecedented insights and data from space, empowering satellite constellations to conduct all-weather imaging without succumbing to the atmospheric hindrances that plague current single-sensor satellites, it said. "This forward technology opens doors for generating highly detailed images through a compact satellite constellation. Upon achieving full operational capacity, this constellation will achieve global coverage within a 12-hour time frame," the start-up said. The capability of constant all-weather, all-time imaging, combined with precise object geometry analysis, holds immense value across diverse sectors such as insurance, precision
