First Indian Gaganyatri Shubhanshu Shukla was received in the International Space Station on June 26, 2025. Today is the historical day when he had interaction with Hon’ble PM of India Shri Narendra Modi Ji. This interaction of Prime Minister inspires and motivates 140 crore citizens of Bharat. Outcome of this ISS mission will contribute for the Indian Gaganyaan Programme. V Narayanan, Chairman ISRO/Secretary DoS/Chairman Space Commission.

Precise air quality monitoring through satellite data: ISRO's OCM-3 AOD product enables air quality analysis over the Indian subcontinent like never before. Researchers are invited to unlock the power of this open data and generate unprecedented insights into aerosol dynamics. isro.gov.in/PreciseAirQualit… MOSDAC: mosdac.gov.in/

Aditya-L1 Mission: HEL1OS captures first High-Energy X-ray glimpse of Solar Flares 🔸During its first observation period from approximately 12:00 to 22:00 UT on October 29, 2023, the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) on board Aditya-L1 has recorded the impulsive phase of solar flares. The recorded data is consistent with the X-ray light curves provided by NOAA's GOES. 🔸Commissioned on October 27, 2023, HEL1OS is currently undergoing fine-tuning of thresholds and calibration operations. The instrument is set to monitor the Sun's high-energy X-ray activity with fast timing and high-resolution spectra. 🔸HEL1OS data enables researchers to study explosive energy release and electron acceleration during impulsive phases of solar flares. HEL1OS was developed by the Space Astronomy Group of the U. R. Rao Satellite Centre, ISRO, Bengaluru. More: ursc.gov.in/hel1os.jsp @NWSSWPC #AdityaL1

Chandrayaan-3 Mission: 🇮🇳Vikram soft-landed on 🌖, again! Vikram Lander exceeded its mission objectives. It successfully underwent a hop experiment. On command, it fired the engines, elevated itself by about 40 cm as expected and landed safely at a distance of 30 – 40 cm away. Importance?: This 'kick-start' enthuses future sample return and human missions! All systems performed nominally and are healthy. Deployed Ramp, ChaSTE and ILSA were folded back and redeployed successfully after the experiment. #Chandrayaan_3 #Ch3

PSLV-C57/Aditya-L1 Mission: The launch of Aditya-L1 by PSLV-C57 is accomplished successfully. The vehicle has placed the satellite precisely into its intended orbit. India’s first solar observatory has begun its journey to the destination of Sun-Earth L1 point.

PSLV-C57/Aditya-L1 Mission: The 23-hour 40-minute countdown leading to the launch at 11:50 Hrs. IST on September 2, 2023, has commended today at 12:10 Hrs. The launch can be watched LIVE on ISRO Website isro.gov.in/ Facebook facebook.com/ISRO YouTube youtube.com/watch?v=_IcgGYZT… DD National TV channel from 11:20 Hrs. IST

Chandrayaan-3 Mission: In-situ Scientific Experiments 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.gov.in/Ch3_Rambha-LP_ne… These quantitative measurements potentially assist in mitigating the noise that Lunar plasma introduces into radio wave communication. Also, they could contribute to the enhanced designs for upcoming lunar visitors. RAMBHA-LP payload development is led by SPL/VSSC, Thiruvananthapuram.

Chandrayaan-3 Mission: In-situ scientific experiments continue ..... Laser-Induced Breakdown Spectroscope (LIBS) instrument onboard the Rover unambiguously confirms the presence of Sulphur (S) in the lunar surface near the south pole, through first-ever in-situ measurements. Al, Ca, Fe, Cr, Ti, Mn, Si, and O are also detected, as expected. Search for Hydrogen (H) is underway. LIBS instrument is developed at the Laboratory for Electro-Optics Systems (LEOS)/ISRO, Bengaluru. isro.gov.in/LEOS.html isro.gov.in/LIBSResults.html #Chandrayaan_3 #Ch3
