Aditya solar mission continuously sending data about Sun: Isro chief

ISRO chief S Somnath on Sunday said that the Aditya L I solar mission of the premier space research agency is continuously sending data about the Sun. Somnath, who was speaking to reporters here after being conferred a special award by jewellery major P C Chandra Group, said several instruments of the spacecraft are working continuously to feed data on many aspects. "We are looking into the sun in a continuous manner - UV magnetic charges observation, corona graph observation, X-ray observation and other things," he said. India's first solar mission craft, Aditya-L1 spacecraft was launched on September 2, 2023. "As we are keeping this satellite for five years, the observation will be analysed as a long-term measure. It is not like your instant news that something has been reported about the sun today, something else will happen tomorrow, things will happen every day," he explained. All observations will happen now but the results will be known later, he said. "Eclipse happens as

Solar mission Aditya L1 will reach destination on January 6: Isro chairman

India's maiden solar mission 'Aditya L1' will reach its destination, the Lagrangian point (L1) which is located 1.5 million km from Earth, on January 6, Indian Space Research Organisation (ISRO) chairman S Somanath said here on Friday. The mission, the first Indian space-based observatory to study the Sun from a halo orbit L1, was launched by ISRO on September 2 from the Satish Dhawan Space Centre (SDSC) at Sriharikota. "Aditya L1 will enter the L1 point on January 6. That is what is expected. Exact time will be announced at appropriate time," Somanath told mediapersons on the sidelines of the Bharatiya Vigyan Sammelan organised by Vijnana Bharati, an NGO working to popularise science. "When it reaches the L1 point, we have to fire the engine once again so that it does not go further. It will go to that point, and once it reaches that point, it will rotate around it and will be trapped at L1," he said. Once Aditya L1 reaches its destination, it will help measure various events ...

Aditya L1 takes STEPS to collect info on energetic particles from space

After India's solar mission Aditya L1 began its journey towards Lagrange point 1 following a key manoeuvre, it has started studying energetic particles in the solar wind from space, and will continue to do so for the rest of its life, a senior astrophysicist said. The study of the solar wind, the continuous flow of charged particles from the sun which permeates the solar system, will be carried out with the help of a device named Supra Thermal & Energetic Particle Spectrometer (STEPS), a part of the Aditya Solar wind Particle EXperiment (ASPEX) payload. STEPS is now working from space. However, it was not sitting idle earlier. It has started functioning from within the magnetic field of the Earth since September 10 when Aditya was 52,000 kilometres above our planet, Dr Dibyendu Chakrabarty, professor of Space and Atmospheric Sciences at the Physical Research Laboratory (PRL) said. STEPS was developed by the PRL with support from the Space Application Centre (SAC) in ...

Aditya L1 successfully undergoes fourth earth-bound manoeuvre: ISRO

Aditya L1 spacecraft, India's first space-based mission to study the Sun, during the early hours on Friday, underwent the fourth earth-bound manoeuvre successfully, ISRO said. "The fourth Earth-bound manoeuvre (EBN#4) is performed successfully. ISRO's ground stations at Mauritius, Bengaluru, SDSC-SHAR and Port Blair tracked the satellite during this operation, while a transportable terminal currently stationed in the Fiji islands for Aditya-L1 will support post-burn operations," the space agency said in a post on X, a platform formerly known as Twitter. The new orbit attained is 256 km x 121973 km, it said: "The next manoeuvre Trans-Lagragean Point 1 Insertion (TL1I) -- a send-off from the Earth -- is scheduled for September 19, around 02:00 Hrs. IST." Aditya-L1 is the first Indian space-based observatory to study the Sun from a halo orbit around the first Sun-Earth Lagrangian point (L1), which is located roughly 1.5 million km from the Earth. The first, second and third earth-boun

Aditya L1 successfully undergoes third earth-bound manoeuvre, says ISRO

Aditya L1 spacecraft, India's first space-based mission to study the Sun, successfully underwent its third earth-bound manoeuvre in the early hours of Sunday, ISRO said. The space agency's Telemetry, Tracking and Command Network (ISTRAC) carried out the operation. "The third Earth-bound manoeuvre (EBN#3) is performed successfully from ISTRAC, Bengaluru. ISRO's ground stations at Mauritius, Bengaluru, SDSC-SHAR and Port Blair tracked the satellite during this operation," the Indian Space Research Organisation ISRO) said in a post on social media platform X. The new orbit attained is 296 km x 71767 km, it said, adding the next manoeuvre is scheduled on September 15, around 2 am. Aditya-L1 is the first Indian space-based observatory that will study the Sun from a halo orbit around the first Sun-Earth Lagrangian point (L1), which is located roughly 1.5 million km from the Earth. The first and second earth-bound manoeuvres were successfully performed on September 3 and 5, respectively.

Four Kerala PSUs part of India's first solar exploration mission Aditya-L1

As India's first solar exploration satellite reached space, four Kerala public sector undertakings, including Keltron, have reason to be delighted as they too have contributed to this achievement by the country. Various products indigenously developed and manufactured by the four PSUs - Keltron, Steel and Industrial Forgings Limited (SIFL), Travancore Cochin Chemicals (TCC) and Kerala Automobiles Ltd (KAL) - have been used in the Aditya L1 mission. This milestone achieved by the PSUs was highlighted by state Industries Minister P Rajeev in a Facebook post. The minister said 38 electronic modules manufactured by the Kerala State Electronics Development Corporation Limited (Keltron) were used in the PSLV-C57 launch vehicle used to send the Aditya L1 satellite into space. In addition to that, Keltron also provided testing support for various types of electronics models required for the mission, he said. Rajeev further said that the forgings for the various stages of the Aditya L1 la
