Aditya-L1 Enters Final Orbit; India Creates Another Landmark: Modi

By LokMarg

In a significant scientific milestone, Indian Space Research Organisation (ISRO) on Saturday injected Aditya-L1 spacecraft – the first dedicated solar mission – into its final destination orbit.

Prime Minister Narenendra Modi and Minister of State for Science and Technology Jitendra Singh were among leaders who hailed the achievement.

Aditya-L1 has reached Lagrange Point L1, about 1.5 million km from earth.

The PSLV-C57.1 rocket carrying the Aditya-L1 orbiter lifted off successfully from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, in September.

The successful launch of the maiden solar mission of the Indian Space Research Organisation (ISRO) came on the heels of the historic lunar landing mission — Chandrayaan-3.

Prime Minister Narendra Modi said India will continue to pursue new frontiers of science for the benefit of humanity.

“India creates yet another landmark. India’s first solar observatory Aditya-L1 reaches it’s destination. It is a testament to the relentless dedication of our scientists in realising among the most complex and intricate space missions. I join the nation in applauding this extraordinary feat. We will continue to pursue new frontiers of science for the benefit of humanity,” he said in post on X.

Jitendra Singh said Aditya L1 will discover the mysteries of sun-earth connection

“From Moon walk to Sun Dance! What a glorious turn of year for Bharat! Under the visionary leadership of PM @narendramodi, yet another success story scripted by Team #ISRO. #AdityaL1 reaches its final orbit to discover the mysteries of Sun-Earth connection,” he said in a post on X.

Commerce and Industry Minister Piyush Goyal also congratulated the scientists and said India’s space journey is unstoppable.

“Wings of Fire! Congratulations to the dedicated scientists at @ISRO for successfully inserting Bharat’s first solar observatory #AdityaL1 into its intended destination. First the moon, now the sun… our space journey is unstoppable!

Aditya L1 has seven different payloads on board, to conduct a detailed study of the sun, four of which will observe the light from the sun and the other three will measure in-situ parameters of the plasma and magnetic fields.

The largest and technically most challenging payload on Aditya-L1 is the Visible Emission Line Coronagraph or VELC. VELC was integrated, tested, and calibrated at the Indian Institute of Astrophysics’ CREST (Centre for Research and Education in Science Technology) campus in Hosakote in collaboration with ISRO.

This strategic location will enable Aditya-L1 to continuously observe the sun without being hindered by eclipses or occultation, allowing scientists to study solar activities and their impact on space weather in real-time.

Also, the spacecraft’s data will help identify the sequence of processes that lead to solar eruptive events and contribute to a deeper understanding of space weather drivers.

Major objectives of India’s solar mission include the study of the physics of solar corona and its heating mechanism, the solar wind acceleration, coupling and dynamics of the solar atmosphere, solar wind distribution and temperature anisotropy, and origin of Coronal Mass Ejections (CME) and flares and near-earth space weather.

By LokMarg

In a momentous recognition of India’s space prowess, the Indian Space Research Organisation (ISRO) has been feted with the prestigious Leif Erikson Lunar Prize by the Husavik Museum here.

The award acknowledges ISRO’s unwavering dedication and indomitable spirit in propelling lunar exploration forward and contributing significantly to unravelling celestial mysteries, particularly through the successful Chandrayaan-3 mission.

“Leif Erikson Lunar Prize has been awarded by Husavik Museum for @ISRO’s indomitable spirit in advancing lunar exploration & contributing to understanding celestial mysteries #Chandrayaan3,” the Indian Embassy in Iceland posted on X.

Indian Ambassador Balasubramanian Shyam received the prestigious prize on behalf of ISRO.

“ISRO Chairman Mr S Somanath sent a message; Amb Mr Shyam received the prize on ISRO’s behalf,” the embassy’s post added.

The triumph of Chandrayaan-3 marked a historic milestone on August 23 when the lander module successfully touched down on the moon’s South Pole. India became the fourth nation, following the United States, China, and Russia, to achieve a successful lunar landing. The mission not only showcased technological prowess but also signalled redemption after the disappointment of the Chandrayaan-2 crash landing four years earlier.

Post-landing, the Vikram lander and the Pragyan rover conducted various tasks on the lunar surface, including detecting the presence of sulfur and other elements, recording relative temperature, and monitoring lunar activities. The success of Chandrayaan-3 further solidified India’s standing in lunar exploration.

Following the lunar triumph, India swiftly moved ahead with its maiden solar mission, Aditya-L1, launched on September 2. The spacecraft has successfully undergone multiple maneuvers, including four earth-bound maneuvers and a crucial Trans-Lagrangean Point 1 Insertion (TL1I) maneuver, enabling it to escape Earth’s sphere of influence.

In the most recent development, the Propulsion Module (PM) of Chandrayaan-3 achieved another feat by transitioning from lunar orbit to Earth’s orbit.

The Indian Space Research Organisation shared the achievement on X, stating, “Chandrayaan-3 Mission: Ch-3’s Propulsion Module (PM) takes a successful detour! In another unique experiment, the PM is brought from Lunar orbit to Earth’s orbit. An orbit-raising manoeuvre and a Trans-Earth injection manoeuvre placed PM in an Earth-bound orbit.” (ANI)

Vikram Lander Is Set Into Sleep Mode: ISRO

By LokMarg

In a major development, the Indian Space Research Organization (ISRO) announced that the ‘Vikram Lander’ has been set into sleep mode at around 08 AM (Indian Standard Time) on Monday morning.

ISRO said that the data collected by the payloads is received at the Earth and the Payloads are now switched off. It is expected by ISRO that Vikram Lander and Pragyaan will awake again on around September 22.

“Vikram Lander is set into sleep mode around 08:00 Hrs. IST today. Prior to that, in-situ experiments by ChaSTE, RAMBHA-LP and ILSA payloads are performed at the new location. The data collected is received at the Earth. Payloads are now switched off. Lander receivers are kept ON. Vikram will fall asleep next to Pragyan once the solar power is depleted and the battery is drained. Hoping for their awakening, around September 22, 2023,” ISRO posted on X.

The Vikram lander was carrying the Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure surface thermal properties, the Instrument for Lunar Seismic Activity (ILSA) to measure seismicity around the landing site, the Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA) to study the gas and plasma environment, and a passive laser retroreflector array provided by NASA for lunar ranging studies.

On August 23, India took a giant leap as the Chandrayaan-3 lander module successfully landed on the moon’s South Pole, making it the first country to have achieved the historic feat and bringing to an end the disappointment over the crash landing of the Chandrayaan-2, four years ago. Overall, India became the fourth country – after the US, China, and Russia – to have successfully landed on the moon’s surface.

After having landed, the Vikram Lander and the Pragyan rover performed different set tasks on the lunar surface, including finding the presence of sulphur and recording relative temperature. Upon landing, the lander and the rover were to operate for one lunar day. One day on the Moon is equal to 14 days on Earth. (ANI)

Chandrayaan-3

Aditya-L1: Countdown For India’s First Mission To Sun Begins

By LokMarg

Shifting focus to its next space odyssey after successfully placing a lander on the moon’s uncharted South Pole region, the Indian Space Research Organisation (ISRO) is all set for the country’s maiden solar mission — Aditya-L1.

The launch of the sun mission is scheduled for Saturday at 1150 IST from the launch pad at Sriharikota, with the launch rehearsal and vehicle internal checks all being completed.

Aditya-L1 is India’s first solar space observatory and will be launched by the PSLV-C57. It will carry seven different payloads to have a detailed study of the sun, four of which will observe the light from the sun and the other three will measure in-situ parameters of the plasma and magnetic fields.

The largest and technically most challenging payload on Aditya-L1 is the Visible Emission Line Coronagraph or VELC. VELC was integrated, tested, and calibrated at the Indian Institute of Astrophysics’ CREST (Centre for Research and Education in Science Technology) campus in Hosakote in collaboration with ISRO.

Aditya-L1 will be placed in a halo orbit around Lagrangian Point 1 (or L1), which is 1.5 million km away from the Earth in the direction of the sun. It is expected to cover the distance in four months’ time.

This strategic location will enable Aditya-L1 to continuously observe the sun without being hindered by eclipses or occultation, allowing scientists to study solar activities and their impact on space weather in real-time. Also, the spacecraft’s data will help identify the sequence of processes that lead to solar eruptive events and contribute to a deeper understanding of space weather drivers.

Major objectives of India’s solar mission include the study of the physics of solar corona and its heating mechanism, the solar wind acceleration, coupling and dynamics of the solar atmosphere, solar wind distribution and temperature anisotropy, and origin of Coronal Mass Ejections (CME) and flares and near-earth space weather.

The atmosphere of the sun, the corona, is what we see during a total solar eclipse. A coronagraph like the VELC is an instrument that cuts out the light from the disk of the sun, and can thus image the much fainter corona at all times, the Bengaluru-based Indian Institute of Astrophysics said.

On August 23, India took a giant leap as the Chandrayaan-3 lander module successfully landed on the moon’s South Pole, making it the first country to have achieved the historic feat and bringing to an end the disappointment over the crash landing of the Chandrayaan-2, four years ago. Overall, India became the fourth country – after the US, China, and Russia – to have successfully landed on the moon’s surface.

After having landed, the Vikram lander and the Pragyan rover performed different set tasks on the lunar surface, including finding the presence of sulphur and recording relative temperature.

Upon landing, the lander and the rover were to operate for one lunar day. One day on the Moon is equal to 14 days on Earth.

The stated objectives of Chandrayaan-3, India’s third lunar mission, were a safe and soft landing on the lunar surface, the rover moving on the moon’s surface, and in-situ scientific experiments.

Chandrayaan-3 is the ISRO’s follow-up attempt after the Chandrayaan-2 mission faced challenges during its soft landing on the lunar surface in 2019 and was eventually deemed to have failed its core mission objectives. (ANI)

By LokMarg

Shifting focus to its next space odyssey after successfully placing a lander on the moon’s uncharted South Pole, the Indian Space Research Organisation (ISRO) on Saturday said the country’s maiden solar mission — Aditya-L1 — will “possibly” be launched on September 2.

Aditya-L1 would be the first space-based Indian observatory to study the Sun.

Speaking to ANI barely minutes after Prime Minister Narendra Modi’s address to scientists at the ISRO’s Bengaluru headquarters, Nilesh M Desai, a top space scientist at the agency and the director of Space Applications Centre (SAC), Ahmedabad, said, “We had planned the ‘Aditya-L1’ mission to study the sun. The mission is ready for launch. There is a possibility that the spacecraft will be launched on September 2.”

He said PM Modi’s address to the scientists at ISRO’s Bengaluru command centre was ‘motivating’.

“PM Modi’s speech was hugely motivating. His announcements will inspire us to plan and execute similar missions going forward. His announcements have filled us with motivation and new zeal to rededicate ourselves to working for the country in the space domain,” Desai told ANI.

Sudheer Kumar N, director, Capacity Building & Public Outreach (CBPO), ISRO told ANI, “I don’t have enough words to express what I felt about PM Modi’s address here. I can’t thank him enough for visiting us here just after landing in India. He said he couldn’t stop himself from visiting us. This was more than what we could expect. His announcements were not only meant to celebrate the success of our lunar landing mission but also to enable future generations to remember the day and the achievement.”

Earlier, speaking to ANI, ISRO chairman S Somanth said the country’s maiden mission to study the sun will be ready for launch in the first week of September.

Prime Minister Narendra Modi on Saturday announced that August 23 will be celebrated as ‘National Space Day’ to mark Chandrayaan-3’s landing on the moon.

He announced that the spot where the ‘Vikram’ lander touched down on the lunar surface would henceforth be known as the ‘Shivshakti’ point while the imprint left by the Chandrayaan-2 on the lunar surface will be called the ‘Tiranga’ point’.

Earlier, on Saturday, PM Modi was accorded a warm reception as he arrived at the ISRO headquarters.

He met the team of scientists involved in the country’s third lunar mission and was pictured embracing ISRO chief S Somanath.

Locals, holding up posters and the tricolour had lined the streets outside the airport to welcome PM Modi.

Upon landing at the HAL airport in Bengaluru, he waved at the cheering locals and raised the slogan “Jai Vigyan Jai Anusandhan (Glory to Science, Glory to Research)”. (ANI)

Chandrayaan-3: Pragyan Rover Walks On Moon

By LokMarg

A video of the Pragyan rover rolling out of Chandrayaan-3 Vikram lander and walking on the lunar surface was released by the Indian Space Research Organisation (ISRO) on Thursday.

From the video released by ISRO, the Indian national flag pasted on its back is visible as the rover began its ‘moonwalk’ on the lunar surface.

Previously, ISRO released visuals of the August 23 soft landing of the Chandrayaan-3 lander Vikram on the moon’s surface, clicked by Chandrayaan-2’s Orbiter High-Resolution Camera.

Upon landing, the lander and the rover will operate and do their set tasks for one lunar day. One day on the Moon is equal to 14 days on Earth.

India took a giant leap on Wednesday evening as the Chandrayaan-3 lander module successfully landed on the moon’s South Pole, making it the first country to have achieved the historic feat and bringing to an end the disappointment over the crash landing of the Chandrayaan-2, four years ago.

Overall, India became the fourth country – after the US, China, and Russia – to have successfully landed on the moon’s surface.

The spacecraft was launched from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota on July 14.

The stated objectives of Chandrayaan-3, India’s third lunar mission, were a safe and soft landing on the lunar surface, the rover moving on the moon’s surface, and in-situ scientific experiments.

However, the Covid-19 pandemic brought an unforeseen delay to the mission’s progress. The approved cost of Chandrayaan-3 is Rs 250 crores (excluding launch vehicle cost).

Chandrayaan-2 mission was only “partially successful” since the lander lost contact after a hard landing, but the ISRO earlier this week successfully established two-way communication between the Chandrayaan-3 lander module and the still orbiting Chandrayaan-2 orbiter. (ANI)

ISRO Shares Images Of Lunar Surface After Soft Landing Of Lander Vikram

By LokMarg

As the lander module of the Chandrayaan-3 made a soft landing near the South pole of the moon, the Indian Space Research Organisation (ISRO) on Wednesday shared images of the lunar surface from Vikram during the descent. 

Taking to social media platform X, formerly called Twitter, ISRO said, “The communication link is established between the Ch-3 Lander and MOX-ISTRAC, Bengaluru. Here are the images from the Lander Horizontal Velocity Camera taken during the descent.” 

As the Vikram lander carrying the Pragyaan rover in its belly touched down on the lunar surface, it marked a giant leap in India’s spacefaring journey providing a well-deserved finale to ISRO’s long years of toil.

This makes India the fourth country – after the US, China, and Russia – to have successfully landed on the moon’s surface; it has earned a place in record books as the first to touchdown on the south side of Earth’s only natural satellite.

Special screenings of the soft landing were organised across the country, including schools, science centres, and public institutions. ISRO made the live action available on the ISRO website, its YouTube channel, Facebook, and public broadcaster DD National TV.
