ISRO’s Aditya-L1 Spacecraft To Enter Its Final Destination Orbit Today; Know All Details Here

Published

on

ISRO will perform the final manoeuvre on Saturday to inject Aditya-L1 spacecraft, the first space-based Indian observatory to study the Sun, into its final destination orbit, some 1.5 million kilometres from the Earth.

Aditya-L1 spacecraft to be placed on Lagrange point 1

According to ISRO officials, the spacecraft will be placed in a halo orbit around Lagrange point 1 (L1) of the Sun-Earth system, about 1.5 million km from the Earth. The L1 point is about one per cent of the total distance between the Earth and the Sun. 

A satellite in a halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultations/eclipses, they said, adding this will provide a greater advantage in observing solar activities and its effect on space weather in real-time.

“This manoeuvre (at around 4 pm on Saturday) will bind the Aditya-L1 to a halo orbit around L1. If we don’t do this, there is a possibility that it will continue its journey, maybe towards the Sun,” an ISRO official told on Friday.

On September 2, 2023, PSLV-C57 blasted off the Aditya-L1 spacecraft

The Polar Satellite Launch Vehicle (PSLV-C57) launched the Aditya-L1 spacecraft from the second launch pad of Satish Dhawan Space Centre (SDSC), Sriharikota, on September 2 last year. After a flight duration of 63 minutes and 20 seconds, it was successfully injected into an elliptical orbit of 235×19500 km around the Earth. 

The spacecraft underwent a series of maneuvers thereafter and headed Sun-Earth Lagrange Point 1(L1), having escaped the Earth’s sphere of influence. 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 directly view the Sun and the remaining three payloads carry out in-situ studies of particles and fields at the Lagrange point L1, thus providing important scientific studies of the propagatory effect of solar dynamics in the interplanetary medium,” according to the space agency.

The suits of Aditya L1 payloads are expected to provide the “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, and propagation of particles and fields, officials said.

Aditya-L1 mission major goals 

The major science objectives of the Aditya-L1 mission are, 1) Study of the Solar upper atmospheric (chromosphere and corona) dynamics. 2) Study of chromospheric and coronal heating, physics of the partially ionized plasma, initiation of the coronal mass ejections, and flares. 3) Observe the in-situ particle and plasma environment, providing data for the study of particle dynamics from the Sun. 4) Physics of the solar corona and its heating mechanism. 5) Diagnostics of the coronal and coronal loops plasma: Temperature, velocity and density. 6) Development, dynamics and origin of coronal mass ejections (CMEs). 7) Identify the sequence of processes that occur at multiple layers (chromosphere, base and extended corona) which eventually leads to solar eruptive events. 8) Magnetic field topology and magnetic field measurements in the solar corona. 9) Drivers for space weather (origin, composition and dynamics of solar wind).

Modi ji served nation tirelessly through 12 years without taking even single day off: Amit Shah

Published

on

New Delhi, June 9: Home Minister Amit Shah on Tuesday said that for the first time ever under Prime Minister Narendra Modi’s leadership over the past 12 years, India has experienced both significant welfare improvements for the poor and remarkable development.

This comes as on this very day in 2024, PM Modi took the oath as the Prime Minister of India for the third consecutive time. Additionally, PM Modi is set to complete 12 years at the helm of the Central government on June 10, marking a political journey that has significantly reshaped India’s electoral and governance landscape.

In a post on X, Shah said, “Honourable Shri Narendra Modi ji took the oath of office as Prime Minister for the third consecutive time on this very day. Under Modi ji’s leadership, over these 12 years, the country has witnessed for the first time the parallel realisation of poor welfare and unprecedented development.”

“Whether it is providing free rations to 80 crore people or launching over 90 airports and more than 140 Vande Bharat trains across the country; whether it is providing pucca houses to over 4 crore poor families or constructing 1.45 lakh kilometers of roads and 3000 km of modern expressways; whether it is providing Rs 5 lakh health insurance to 50 crore people and gas connections to over 10 crore families or making India the world’s fastest-growing economy; Modi ji has served the nation and its citizens tirelessly through these 12 years without taking even a single day off,” the Home Minister added.

The PM Modi-led government’s era has also been marked by a series of high-profile infrastructure and nation-building projects, including the new Parliament building, Central Vista redevelopment, Kartavya Path, Vande Bharat trains, the Statue of Unity, INS Vikrant, the Kashmir rail link, Noida International Airport, Namo Bharat RRTS and the Ganga Expressway.

Hailing PM Modi’s leadership, Shah said, “When leadership’s intent is pure, goals are in the national interest, and dedication is complete, only then are such transformations possible.”

From his first swearing-in ceremony in 2014 to securing successive mandates in 2019 and a historic third consecutive term in 2024, PM Modi has emerged as one of India’s longest-serving leaders.

On June 10, PM Modi will surpass independent India’s first PM, Jawaharlal Nehru, to become India’s longest-serving continuously elected Prime Minister with 4,399 days.

Nehru was first elected to the post in 1952 (his previous stint from 1947-52 was as head of an interim government, as elections were yet to be institutionalised and held). Indira Gandhi had a fractured tenure totalling 14 years. Prime Minister Modi has an unbroken tenure of 12 years as the PM, and still has three more years to go for the current tenure.

Patna court stays arrest of Khan Sir in coaching centre firing case

Published

on

Patna, June 9: A Patna court on Tuesday granted interim relief to popular educator Faisal Khan, widely known as Khan Sir, by staying his arrest in connection with the recent coaching centre firing case.

The District Judge’s court pronounced its order on Tuesday after reserving its verdict on Khan Sir’s anticipatory bail plea following a hearing on Monday.

While the court has not yet granted anticipatory bail, it has directed the police not to take any coercive or punitive action against him until further proceedings.

The court has also sought the case diary and details of Khan Sir’s criminal history from the investigating agency. The matter will now be heard again on June 30.

Seeking the case diary and the accused’s criminal record is a routine judicial procedure while considering an anticipatory bail application.

Although the bail plea remains pending, the stay on arrest has provided major relief to Khan Sir, who had been facing the possibility of immediate police action.

After the court order, Khan Sir’s counsel, Advocate Arvind Kumar Mahuar, told media that Khan Sir is now free to move around wherever he wants as the court has given him protection from the arrest.

The case stems from an incident that occurred on the night of June 2, when unidentified individuals allegedly attacked Khan Global Studies, the coaching institute run by Khan Sir in Patna.

Following the incident, police arrested Roshan Anand, the owner of Gyan Bindu Coaching Institute, and sent him to judicial custody.

The controversy intensified after a video surfaced showing two security guards allegedly firing shots into the air outside the coaching institute during the attack.

The police subsequently arrested both guards and lodged a case against them. Later, Khan Sir was also named in the case.

Police registered an FIR against Khan Sir under provisions related to attempted murder and the Arms Act. Since the registration of the case, he had reportedly remained out of the police’s reach.

Law enforcement officials had visited his coaching institute in an attempt to apprehend him, but he was not found there.

Mumbai : BJP leader Naveen Rana’s meeting with Nationalist Congress Party president Sunitra Pawar has sparked fresh debate in political circles. There are speculations that the meeting was held to deliberate on the Rajya Sabha seat that fell vacant after Sunitra Pawar resigned as an MP. After Vikram Kakde, who is outside the party, was nominated for the Pune Local Authority constituency of the Legislative Council, preparations are being made to send Naveen Rana, who has now joined the BJP, to the Rajya Sabha, a debate that has angered several senior leaders in the NCP.

Rajya Sabha seat: Chhagan Bhujbal is interested Senior party leader Chhagan Bhujbal is interested in this Rajya Sabha seat. However, after the discussion of Navneet Rana’s name started, an open discussion has started that the influence of MP Partha Pawar’s group on the decision-making process in the party has increased. It is also being said that Praful Patel is not very active in the party after his name was removed from the post of National Executive President. It is also being said that Sunil Tatkre is also angry and the number of angry leaders in the party is increasing. The last date for filing nominations for this Rajya Sabha seat is June 8, so various leaders in the party have started lobbying for this seat and efforts to get nomination are going on rapidly. After all, the focus of political circles is on who will give the party a candidate.

Navneet Rana, who was elected as an independent candidate with the support of the Nationalist Congress Party in the 2019 Lok Sabha elections, joined the BJP in 2024. However, there are talks about her political revival after her defeat in the Lok Sabha elections. It is also said that she has recently contacted some senior BJP leaders. However, it is known that she was advised to contact them because the vacant Rajya Sabha seat is in the NCP quota. It is believed that she met Sunita Pawar only after that.

Elections have been announced for 24 vacant Rajya Sabha seats and by-elections. This includes 4-4 from Andhra Pradesh, Gujarat and Karnataka, 3-3 from Rajasthan and Madhya Pradesh, 2 from Jharkhand and one each from Manipur, Meghalaya, Arunachal Pradesh and Mizoram. Apart from this, by-elections for one seat each from Maharashtra and Tamil Nadu will also be held on the same day. Voting will be held on June 18 and the results will be announced on the same day. Meanwhile, there is an important development. It is being told that former MP Naveen Rana is trying to get the Rajya Sabha nomination. The Rajya Sabha nomination from the Nationalist Congress Party quota will be announced soon. For this, Naveen Rana met Sunita Pawar and Partha Pawar on Wednesday. Yesterday, Naveen Rana and Ravi Rana also met Chief Minister Devendra Fadnavis. Therefore, it is being said that an attempt is being made to nominate Navneet Rana on the NCP quota seat. However, will Navneet Rana give up his quota seat for the NCP? This is also a question. So, will this meeting result in Navneet Rana being nominated in place of Sunitra Pawar? This will become clear in the coming days.

Rajya Sabha Seat: Amul Matkari’s social media post is under discussion, Amul Matkari has posted in this regard and said that the vacant Rajya Sabha seat of Smt. Sunitra Vahini belongs only to NCP! No one else should claim this and put up a front. The name of the NCP party is “Ajit Dada”. Therefore, the decision taken by Smt. will be final. This party is a party that is under the sway of Ajit Dada. That’s all for now.
