The Indian Area Analysis Organisation (Isro) Thursday obtained the most important payload — Seen Line Emission Coronagraph (VELC) — which might fly on Aditya L1, India’s first devoted scientific mission to check the Solar by the Indian Institute of Astrophysics (IIA) at a operate in Bengaluru.
IIA has constructed the VELC at its Centre for Analysis and Training in Science and Know-how (CREST) campus in Hoskote. Isro will now conduct additional testing of VELC and its eventual integration with the Aditya-L1 spacecraft.
Aditya L-1 is a deliberate coronagraphy spacecraft. VLEC is designed to carry out duties like imaging and spectroscopy to unravel the secrets and techniques of the photo voltaic corona which is the outermost layer of the Solar and is without doubt one of the most tough attributes of the star to be studied.
Secretary, division of area and chairman, Isro, S Somnath stated, “VELC is a primary instrument. Aditya L1 will have a set of instruments which will play an important role in observing the sun. After AstroSat, this is a very important scientific mission which Isro has undertaken. The journey for building this complex satellite has been a long one. People in this domain know the challenges in building an instrument like VELC. Understanding the effect of the Sun on Earth and its surroundings has become very important now and Aditya-L1 aims to shed light on this topic. It has taken 15 years for VELC from concept to completion, and this period was needed for a complex system like this. The VELC has been the finest collaboration between IIA and Isro.”
He additionally stated the launch of Aditya-L1 is predicted to be round June or July this yr.
“Isro aims to play an important role in future science experiments in space and an ecosystem needs to be created for this, including a roadmap for the next few decades. Isro encourages Indian scientists to come up with new and novel ideas for future space science instruments that have not been done before by others in the world. Many students tell me that they want to become astrophysicists and institutes like IIA should further enhance their efforts to explain their work to the public,” Somnath added.
Earlier, this mission was conceived as Aditya-1 with a 400 kg class satellite tv for pc carrying one payload, the VELC and was deliberate to be launched in an 800 km low earth orbit.
“Since a satellite placed in the halo orbit around the first Lagrangian point (L1) of the Sun-Earth system has the major advantage of continuously viewing the Sun without any occultation/eclipses, the Aditya-1 mission has now been revised to Aditya-L1 mission. The satellite will be inserted in a halo orbit around the L1, which is 1.5 million km from the Earth towards the Sun,” IIA stated.
Langrangian factors are positions in area the place objects despatched there have a tendency to remain put. L1 is situated 1.5 million kilometres from Earth.
The satellite tv for pc carries further six payloads -Photo voltaic Ultraviolet Imaging Telescope (SUIT), Aditya Photo voltaic Wind Particle Experiment (ASPEX), Plasma Analyser Package deal for Aditya (PAPA), Photo voltaic Low Vitality X-ray Spectrometer (SoLEXS), Excessive Vitality L1 Orbiting X-ray Spectrometer (HEL1OS) and Magnetometer.
Professor Annapurni Subramaniam, Director of Indian Institute of Astrophysics, congratulated the VELC group and stated, “VELC is a team effort and is a major milestone for the institute. The effort has involved close collaboration between IIA, Isro and many industries across India. We look forward to exciting science results coming from this payload after it is operational.”
The Principal Investigator of the VELC payload, Professor Raghavendra Prasad stated, “No other solar coronagraph in space has the ability to image the solar corona as close to the solar disk as VELC can. It can image it as close as 1.05 times the solar radius. It can also do imaging, spectroscopy and polarimetry at the same time, and can take observations at a very high resolution (level of detail) and many times a second”. This functionality will revolutionise photo voltaic astronomy around the globe and the info is predicted to reply many excellent issues within the area.”
Nigar Shaji of Isro, the Programme Director of Aditya-L1, stated, “This is one of the best days for the Aditya-L1 team and for myself.”
The VELC group of IIA flagged off the truck housing the VELC. The payload has been positioned in a container and the group have been constantly monitoring its well being utilizing sensors positioned inside. The payload will probably be taken to URSC Isro on Friday morning.
