ISRO releases second set of scientific data from Aditya-L1 mission

ISRO releases second set of Aditya-L1 solar mission data, accessible on ISSDC website for researchers and students.

The Indian Space Research Organisation (ISRO) has released the second set of scientific data from the Aditya-L1 solar mission.

“The datasets comprise valuable scientific information about the Sun’s photosphere, chromosphere and its outer atmosphere (corona) along with the in-situ particles and magnetic field measurements at first Earth-Sun Lagrange Point L1,” ISRO said.

The Aditya L1 datasets will be accessible from the website of the Indian Space Science Data Centre (ISSDC) portal.

To access the Aditya-L1 data via ISSDC website, one has to visit https://www.issdc.gov.in/adityal1.html, navigate to data download section. Data may be accessed directly on PRADAN portal links https://pradan.issdc.gov.in/al1 or https://pradan1.issdc.gov.in/al1. “ISRO encourages the community of researchers and students to utilise these datasets. The user manuals to analyse Aditya-L1 payload data are also available on the above web address after registration,” ISRO said.

The maiden datasets from Aditya-L1 were released by ISRO on January 6, and a national meet was organised.

Aditya-L1, at present, is observing the Sun during its third revolution in the Halo orbit around Lagrange Point (L1).

The Aditya-L1 mission was launched on September 2, 2023 by ISRO onboard the PSLV C-57 rocket. On January 6, 2024, the spacecraft was successfully placed in a large halo orbit around first Earth-Sun Lagrange Point known as Lagrange Point (L1). The L1 point is 1.5 million kilometres away from Earth towards the Sun.
