ISRO invites proposals from Indian researchers to study data from Aditya-L1 mission
New Delhi (PTI): The Indian Space Research Organisation (ISRO) announced on Thursday that it is inviting proposals from the Indian solar physics community to access data from the Aditya-L1 mission, the first space-based Indian mission to study the Sun.
This is the second such formal call from ISRO for Indian scientists to access the Aditya-L1 mission data; the first call was made in January.
"At present, there are over 27 TB of data in the 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 second Announcement of Opportunity (AO) inviting proposals from the Indian solar physics community for Aditya-L1 observation time," the ISRO said in a statement.
Proposals can be submitted by Indian scientists and researchers based at institutes, universities, or colleges in India. The applicants should be involved in research in the area of solar science and equipped to submit proposals as principal investigators for solar observations with the necessary scientific and technical justification.
The approved observations for this second AO cycle will take place between July and September.
Launched in September 2023, the Aditya-L1 mission was successfully inserted into a halo orbit around the first Lagrangian point (L1) in the Sun-Earth system in January 2024. This L1 point, located around 1.5 million km away from Earth, offers the unique advantage of continuous, uninterrupted observation of the Sun, free from eclipses or occultation.
The Aditya-L1 mission carries seven scientific payloads -- four for remote sensing and three for in-situ measurements.
"The remote sensing instruments observe different layers of the Sun, including the photosphere, chromosphere, and corona, using various wavelengths of electromagnetic radiation," ISRO said.
The in-situ payloads, including particle detectors and magnetometers, collect data on the space environment around L1.

Karnataka Lokayukta to register case, probe Bowring wall collapse
Bengaluru (PTI): Karnataka Lokayukta Justice B S Patil on Thursday took serious note of the compound wall collapse at Bowring and Lady Curzon Hospital in the city that killed seven people, and announced registration of a case on its own while warning of action against officials found responsible.
The Lokayukta, who visited the site and conducted an inspection, expressed strong displeasure over the incident and questioned the inaction of authorities, even as police and emergency teams had earlier rushed to the spot to rescue victims trapped under the debris following heavy rain, strong winds and a hailstorm on Wednesday evening.
“I will now register a suo motu case. This is not just about this one incident — such incidents must not occur anywhere in the state or the city in the future,” Justice Patil told reporters.
Seven people, including a six-year-old girl, were killed and seven others injured when the compound wall collapsed as rain-battered victims had taken shelter near it, according to police. The victims included people from Kerala who were in the city on a study tour.
Calling for systemic accountability, the Lokayukta said, “Dilapidated buildings and weakened compound walls, especially in areas with public access, must first be identified. They must either be repaired, demolished, or rebuilt.”
He added that responsibility would be fixed on officials of the BBMP and the concerned departments.
Justice Patil said that hearings would be conducted and preventive action initiated, while also probing those responsible for it, how the incident could have been prevented, and why it was not prevented.
A Scene of Crime Officers (SOCO) team and a Forensic Science Laboratory (FSL) team also inspected the site, while police cordoned off Kovil Street to facilitate the probe.
Deputy Chief Minister D K Shivakumar said the government had initiated measures following the rain-related incidents and stressed preparedness.
“Since last night we have initiated measures regarding the rains. When it rains heavily, we must be prepared, and we are working towards that,” he told reporters here.
On the wall collapse, Shivakumar said, “I will not directly blame any officials. It was an old wall, and trees had grown alongside it. Due to that pressure, it collapsed.”
The Deputy CM said instructions had been issued to identify such vulnerable structures and clear areas around them, including relocating street vendors.
Karnataka Medical Education Minister Sharan Prakash Patil said a technical assessment had been ordered.
“This is a very serious matter. Innocent people have been affected. We are issuing directions to the engineers to find out why this compound wall collapsed and to assess its structural strength,” he told reporters after inspecting the spot.
The Minister noted that the wall was ‘very old’ and required thorough examination to prevent recurrence.
Speaking to reporters, Congress president Mallikarjun Kharge asked the Karnataka government to take precautions to ensure that incidents like the collapse of the Bengaluru government hospital compound wall, which caused loss of life, should not repeat.
Meanwhile, addressing a press conference, Shivajinagar MLA Rizwan Arshad said the collapse raised questions about construction and maintenance practices.
“If a wall collapses within 25 years of its construction, it needs to be examined -- whether there was any technical issue, or if anything was altered inside, weakening it. All this can only come out through a technical investigation,” he said.
The Congress MLA also called for wider structural audits across the city, stating that all such structures, whether private or government, must be audited.
He urged citizens to support victims, saying it was a collective responsibility in times of crisis.
