Bengaluru (PTI): Aditya-L1, the first space-based Indian observatory to study the Sun, is getting ready for its launch soon, ISRO said on Monday.

The satellite, realised at U R Rao Satellite Centre here, has arrived at the ISRO's spaceport in Sriharikota in Andhra Pradesh, the Bengaluru-headquartered national space agency said in an update on the mission.

"Mostly September first week," an ISRO official told PTI when asked about the date of the launch.

The spacecraft is expected to be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million kilometres from the Earth.

A satellite placed in the halo orbit around the L1 point has a major advantage of continuously viewing the Sun without any occultation/eclipses, ISRO noted. "This will provide a greater advantage of observing the solar activities and its effect on space weather in real time," it said.

The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun (the corona) using electromagnetic and particle and magnetic field detectors.

Using the special vantage point L1, four payloads will directly view the Sun and the remaining three payloads would carry out in-situ studies of particles and fields at the L1, thus providing important scientific studies of the propagatory effect of solar dynamics in the interplanetary medium.

"The suits of Aditya L1 payloads are expected to provide most crucial information to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, propagation of particle and fields etc.," ISRO said.

The major science objectives of the Aditya-L1 mission are: study of solar upper atmospheric (chromosphere and corona) dynamics; study of chromospheric and coronal heating, physics of the partially ionised plasma, initiation of the coronal mass ejections, and flares; observe the in-situ particle and plasma environment providing data for the study of particle dynamics from the Sun; physics of solar corona and its heating mechanism; diagnostics of the coronal and coronal loops plasma: temperature, velocity and density; development, dynamics and origin of coronal mass ejections; identify the sequence of processes that occur at multiple layers (chromosphere, base and extended corona) which eventually leads to solar eruptive events; magnetic field topology and magnetic field measurements in the solar corona; drivers for space weather (origin, composition and dynamics of solar wind).

The instruments of Aditya-L1 are tuned to observe the solar atmosphere, mainly the chromosphere and corona, while the in-situ instruments will observe the local environment at L1.

Bengaluru, Mar 6 (PTI): The Karnataka Assembly on Thursday passed the Bangalore Palace (Utilisation and Regulation of Land) Bill, reaffirming state ownership over 472 acres and 16 guntas of land here, amid protests by the opposition BJP.

During the discussion, Karnataka Law and Parliamentary Affairs Minister H K Patil said the state government would have to provide Rs 200 crore worth of Transfer of Development Rights (TDR) for each acre of land, which means that for 15 acres, Rs 3,000 crore worth of TDR would be issued.

“If we accept it, then this 2-km stretch of road will become the costliest road in the world. If we accept it then how are we going to develop the city in later stages? How will you carry out development works?” asked Patil.

He also pointed out that this question was raised not only under the Congress government but also during the previous BJP regime.

However, the BJP-led cabinet has opposed the project.

“Suppose we agree to it then, what will be the valuation of the 472 acres? It will be lakhs and lakhs of crores of rupees. Can we accept?” Patil wondered.

The Minister said the government had previously exercised its executive powers to issue an ordinance, which was approved by the Governor. Now the government is bringing a bill with two amendments.

“In this bill, we have made provisions either to develop or drop the road development work,” Patil explained.

However, BJP state president B Y Vijayendra and BJP MLA Arvind Bellad opposed the move, alleging that the government was targetting Yaduveer Krishna Datta Chamaraja Wadiyar, the scion of the Mysuru royal family, and the BJP MP from Mysuru-Kodagu constituency out of political vendetta.
“We talk of 472 acres of Mysuru Maharaja but here there are many Maharajas who too own 400 acres, 500 acres and thousands of acres of land, which is known to everyone,” Bellad said.

He slammed the Congress government, saying political power should not be misused for personal vendetta.

“Why (the then Deputy Chief Minister) Siddaramaiah brought the law in 1996 pertaining to the Bangalore Palace? Why are you setting eyes on the Bangalore Palace?” he asked.

Vijayendra charged that Wadiyar won the election on BJP ticket so the state government realised that it should acquire it.

“This bill has been brought for political vengeance. We are not discussing whether Rs 3,000 crore is exorbitant or not but the moment Yaduveer became MP, the state government woke up. You should be ashamed. This house should not be used for political vendetta,” he said.

Intervening, Minister Priyank Kharge said Vijayendra should not have raised it because the intention behind building the road was noble.

According to him, the BJP too had the same plan when it was in power.

He sought to know whether thousands of crores of rupees be spent on a road which should have cost significantly less.

In response, BJP MLA B A Basavaraj (Byrathi) said issuing TDR will not be a burden on the state government and appealed to the ruling Congress to reconsider its stance.

Minister Ramalinga Reddy too explained that the Karnataka government acquired the entire land way back in 1996.

The Mysuru royal family went to the High Court, which gave ruling in favour of the state government. The royal family then approached the Supreme Court, where the case is still going on, the Minister pointed out.

“The final judgment is pending in the SC to decide whether the acquisition was right or wrong. If the SC says it’s the royal family’s property then let it be so. If the order is in the state government’s favour then we can take a decision. The bill is only about it,” Reddy explained.

Speaker U T Khader then called for a voice vote and the bill was passed by the Assembly amidst opposition BJP’s discontent.
