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).

J&K Heading For ‘Historic’ Assembly Elections Under National Flag & Constitution: Amit Shah

J&K Heading For 'Historic' Assembly Elections Under National Flag & Constitution: Amit Shah

Jammu, Sep 7: Union Home Minister Amit Shah on Saturday assured restoration of statehood to Jammu and Kashmir after the assembly polls, which he said are the first under the national flag and the Constitution following the abrogation of Article 370 by the Modi government.

He accused the Congress-National Conference alliance of making attempts to revive the “old system”.

The NDA government will not allow the revival of terrorism, “autonomy”, and injustice with any community including Gujjars, Pahari, Bakerwals and Dalits who were granted reservation by the BJP dispensation, he said.

Shah is in Jammu on a two-day visit to boost the BJP’s election campaign for the three-phase assembly elections, beginning September 18.

He released the party’s manifesto on his first day of visit on Friday and also chaired two crucial meetings with senior leaders to discuss the campaign strategy.

“The coming elections in J-K are historic because after Independence, the polls are happening the first time under our national flag and Constitution, unlike in the past practice of two flags and two constitutions. We have only one prime minister from Kashmir to Kanyakumari and he is Modi,” the home minister told a BJP workers’ rally here on Saturday.

Taking a dig at the National Conference-Congress alliance, Shah alleged they are trying to push Jammu and Kashmir into the fire of terrorism once again when the government has brought down terror incidents in the union territory by 70 percent.

“The National Conference and the Congress will never be able to form a government in J-K, be confident about it,” Shah told the party workers, encouraging them to ensure the success of the BJP candidates to form the next government.

Chandrababu Naidu Narrowly Escapes As Speeding Train Passes Inches Away From Him During Flood Inspection In Vijayawada

Published

on

Andhra Pradesh Chief Minister N Chandrababu Naidu had a narrow escape while inspecting flood-affected areas in Vijayawada. On September 3, Naidu was on a small bridge evaluating the damage caused by recent floods when a speeding passenger train passed dangerously close to him. 

Naidu, along with his security personnel and officials, was standing near the railing on a narrow platform when the train whizzed by. A video of the incident has gone viral, showing the Chief Minister and his team standing just inches away from the fast-moving train. Passengers aboard the train were seen waving at Naidu as it sped past. Fortunately, no one was injured during the incident.

Situation worsens due to heavy rains

Meanwhile, the flood situation in Andhra Pradesh has worsened due to heavy rains, claiming the lives of at least 32 people.

Vijayawada and surrounding areas have been particularly hard-hit, with thousands displaced from low-lying regions.

The NTR district, which encompasses Vijayawada, has suffered the most, with 24 fatalities. Other severely affected areas include Guntur, with seven deaths, and Palnadu, with one reported death.

More than 40,000 people have been moved to relief camps across the state as water levels continue to rise. Farmers, too, have borne the brunt of the flooding, with over 2.35 lakh farmers reporting significant crop damage due to the unrelenting rains.

In response to the crisis, Andhra Pradesh Deputy Chief Minister Pawan Kalyan has donated Rs 5 crore for flood relief. His contribution is aimed at supporting recovery efforts across the state, with 400 panchayats set to receive Rs 1 lakh each.

“I will make sure these funds are directly deposited into the panchayats’ accounts, ensuring they are used for immediate flood recovery,” said Kalyan in a statement.

The Andhra Pradesh government continues to monitor the situation closely, working to provide relief and assistance to affected areas as rains persist across the region.
