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).

Monsoon Havoc In Himachal Pradesh Claims 257 Lives Since June, 37 Missing And Over 1,000 Houses Destroyed

Published

Shimla: The monsoon havoc in Himachal Pradesh has claimed 257 lives since June 20, according to the Himachal Pradesh State Disaster Management Authority (HP SDMA).

District-wise data shows that Mandi (26 deaths), Kangra (28), and Kullu (11) were among the worst-affected in rain-triggered disasters.

Among the deaths, 133 were deaths reported in rain-related incidents such as landslides, flash floods, drowning, and electrocution, and another 124 fatalities in road accidents,.

The cumulative report released on Friday evening paints a grim picture of widespread destruction. The state has also recorded 331 people injured and 37 missing during the ongoing monsoon season.

Landslides and flash floods alone have caused 16 deaths, while 27 people drowned in swollen rivers and nullahs. Other casualties were reported due to lightning, fire, snake bites, electrocution, and accidental falls.

In addition to human loss, the state reported massive damage to property and infrastructure. Over 1,028 houses were fully damaged and another 2,157 partially damaged, besides 285 cow sheds and 699 shops and factories destroyed. Public property worth more than Rs 2,14,403 crore has been lost, including extensive damage to roads, power lines, water schemes, and government institutions.

Animal losses have also been severe, with 1,625 cattle heads and over 25,700 poultry birds perishing in the rains.

The HPSDMA noted that Mandi district alone accounted for the heaviest financial damage, exceeding Rs 1,180 crore, followed by Kangra and Kullu districts.

Meanwhile, Mandi district reported the highest disruption, with 203 roads blocked and 458 transformers out of service, followed by Kullu where 79 roads remain closed, including NH-305 at Jhed (Khanag) due to a major landslide. Water supply schemes were also severely affected in Chamba (24), Kangra (41), and Mandi (44).

In Kinnaur, six roads including NH-5 were blocked after heavy downpours, while Kullu and Lahaul-Spiti reported widespread outages due to flash floods and HT line faults.

Authorities cautioned that intermittent rainfall in the coming days may worsen the situation, and appealed to people to avoid travel through vulnerable stretches.

Officials warned that the situation remains critical with rains expected to continue, urging residents to avoid travel through vulnerable stretches and follow safety advisories.

Aadhaar-Based Face Authentication Doubles To 200 Crore Transactions In Just 6 Months

Published

on

Aadhaar-based face authentication has set new benchmark, doubling from 100 crore to 200 crore transactions in just 6 months, the government said on Monday.

Aadhaar Face Authentication lets Aadhaar holders verify their identity instantly, securely, and contactless anytime, anywhere, no documents needed.

On August 10, 2025, UIDAI celebrated a landmark 200 crore transactions of Face Authentication, showcasing India’s rapid move towards seamless, secure, and paperless authentication, according to IT Ministry.

The pace of adoption has been exponential. 50 crore transactions were recorded by mid-2024. The number doubled to 100 crore transactions in January 2025 in just about five months. In less than six months, this figure has again doubled, reaching the 200 crore milestone, the ministry informed.

“Reaching 200 crore Aadhaar Face Authentication transactions in such a short time underlines the trust and confidence that both residents and service providers have in Aadhaar’s secure, inclusive, and innovative authentication ecosystem,” said Bhuvnesh Kumar, Chief Executive Officer (CEO), UIDAI.

The journey from 100 crore to 200 crore transactions in under six months is a testament to its scalability and the country’s digital readiness.”

He further added, “From villages to metros, UIDAI is joining forces with governments, banks, and service providers to make Aadhaar Face Authentication a grand success and by giving every Indian the power to prove their identity instantly, securely, and anywhere.”

The swift rise from 100 crore to 200 crore Aadhaar Face Authentication transactions in just six months reflects the core vision of Digital India, transforming the country into a digitally empowered society and knowledge economy.

By enabling instant, secure and paperless identity verification across every corner of the nation, UIDAI is strengthening the backbone of digital governance.

“This milestone is not just about numbers, it is a testament to how inclusive technology, when scaled efficiently, can bridge divides, empower citizens and accelerate India’s journey towards a truly connected and confident digital future,” said the ministry.
