On the 2nd day of India’s maiden star mission, Aditya-L1 reaching the Lagrangian constituent (L1), the Indian Space Research Organisation (ISRO) connected Tuesday (January 6, 2026) made the Announcement of Opportunity (AO) soliciting proposals for the archetypal AO rhythm observations.
The Aditya-L1 spacecraft reached the L1 point connected January 6, 2024, 127 days aft it was launched connected September 2, 2023, and since past has been making continuous and broad observations of the Sun from the Sun–Earth L1 point.
According to ISRO technological information from the ngo are regularly released successful nationalist domain for planetary technological utilization.
To maximise
“At contiguous determination are much than 23 TB information successful nationalist domain and respective important technological results person been published successful International adjacent reviewed journals. To further maximise the technological instrumentality from this unsocial mission, the ISRO has released the archetypal AO inviting proposals from the Indian star physics assemblage for Aditya-L1 reflection time,” ISRO said.
It added that this L1 point, located astir 1.5 cardinal kilometers distant from Earth, offers the unsocial vantage of continuous, uninterrupted reflection of the Sun, escaped from eclipses oregon occultation.
This announcement soliciting proposals for Aditya-L1 reflection is unfastened to Indian scientists and researchers residing and moving astatine institutes, universities and colleges successful India who are progressive successful probe successful the country of star subject and are equipped to taxable proposals arsenic Principal Investigators (PIs) for star observations with indispensable technological and method justification and tin analyse the data, if reflection is made based connected approvals.
Seven payloads
There are 7 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 upwind Particle Experiment (ASPEX); Plasma Analyser Package For Aditya (PAPA); and Advanced Tri-axial High Resolution Digital Magnetometers
Under the archetypal AdityaL1 AO, eligible candidates tin utilize reflection clip from the VELC and the SUIT payloads. For this, proposals indispensable beryllium submitted electronically done the Aditya-L1 Proposal Processing System (ALPPS) hosted astatine the Indian Space Science Data Centre (ISSDC).
Approved observations for this archetypal AO rhythm volition beryllium conducted betwixt April 2026 and June 2026.
