On the second anniversary of India’s maiden photo voltaic mission, Aditya-L1 reaching the Lagrangian level (L1), the Indian Space Research Organisation (ISRO) on Tuesday (January 6, 2026) made the Announcement of Opportunity (AO) soliciting proposals for the primary AO cycle observations.
The Aditya-L1 spacecraft reached the L1 point on January 6, 2024, 127 days after it was launched on September 2, 2023, and since then has been making steady and complete observations of the Sun from the Sun–Earth L1 level.
According to ISRO scientific data from the mission are recurrently launched in public area for international scientific utilization.
To maximise
“At present there are more than 23 TB data in public domain and several important scientific results have been published in International peer reviewed journals. To further maximise the scientific return from this unique mission, the ISRO has released the first AO inviting proposals from the Indian solar physics community for Aditya-L1 observation time,” ISRO mentioned.
It added that this L1 level, situated roughly 1.5 million kilometers away from Earth, presents the distinctive benefit of steady, uninterrupted remark of the Sun, free from eclipses or occultation.
This announcement soliciting proposals for Aditya-L1 remark is open to Indian scientists and researchers residing and dealing at institutes, universities and schools in India who’re concerned in analysis within the space of photo voltaic science and are outfitted to submit proposals as Principal Investigators (PIs) for photo voltaic observations with needed scientific and technical justification and may analyse the data, if remark is made based mostly on approvals.
Seven payloads
There are seven payloads onboard Aditya-L1: Visible Emission Line Coronagraph (VELC); Solar Ultraviolet Imaging Telescope (SUIT); Solar Low Energy X-ray Spectrometer (SoLEXS); High Energy L1 Orbiting X-ray Spectrometer (HEL1OS); Aditya Solar wind Particle Experiment (ASPEX); Plasma Analyser Package For Aditya (PAPA); and Advanced Tri-axial High Resolution Digital Magnetometers
Under the primary AdityaL1 AO, eligible candidates can make the most of remark time from the VELC and the SUIT payloads. For this, proposals have to be submitted electronically by the Aditya-L1 Proposal Processing System (ALPPS) hosted on the Indian Space Science Data Centre (ISSDC).
Approved observations for this primary AO cycle will probably be carried out between April 2026 and June 2026.
