NATIONAL: SPACE FRONTIERS : India’s first National Space Day: August 23rd, 2024 – PM Modi and ISRO chief reflect on India’s space milestones

Prime Minister Narendra Modi on Friday extended his greetings to the nation on the occasion of the first National Space Day. In a message shared on X, the Prime Minister expressed immense pride in India’s remarkable achievements in the space sector.

“Greetings to everyone on the first National Space Day. We recall with great pride our nation’s achievements in the space sector. It is also a day to laud the contributions of our space scientists,” Prime Minister Modi said.

Highlighting the government’s commitment to advancing the space sector, the Prime Minister said, “Our government has taken a series of futuristic decisions relating to this sector, and we will do even more in the times to come.”

Indian Space Research Organisation (ISRO) Chairman S. Somanath praised Prime Minister Narendra Modi for his role in strengthening India’s space ecosystem.

Speaking to ANI, Somanath highlighted recent policy reforms and initiatives under the leadership of PM Modi toward advancing the space sector.

The ISRO chief said that PM Modi’s leadership has been crucial in several key policy interventions in India’s space sector. “As Prime Minister, Modi has not only created but also implemented policies through the governmental system,” he said.

Underscoring three major initiatives, the ISRO chief said, “After the space sector reforms, we worked on a space policy. This new policy clearly defines the roles and responsibilities of the Department of Space, ISRO, and NewSpace India Limited (NSIL), paving the way for greater private sector involvement in space activities.”

“A foreign direct investment policy has also been announced, allowing private and foreign investments in the space sector with certain controls and regulations that were not possible earlier. The third initiative, undertaken by the Department of Science and Technology (DST), involves the geospatial policy. This policy makes all geospatial and satellite data freely available up to a five-meter resolution, creating secondary effects,” he added.

Reflecting on recent milestones, Somanath recalled the Prime Minister’s live participation in the Chandrayaan-3 moon landing event. “I remember our Prime Minister Modi watching the live transmission and taking a moment from the BRICS summit to join us,” he said.

Somanath also recounted Modi’s visit to the Vikram Sarabhai Space Centre, where he showed keen interest in the Gaganyaan mission and other space projects.

“We were asked to prepare a long-term roadmap, a vision for space 2047 in the Amritkaal. The Prime Minister was delighted with our presentation on future space missions, including the Gaganyaan program and plans for a space station,” Somanath said.

M. Sankaran, Director of the U R Rao Satellite Centre (URSC), also recalled the Prime Minister’s visit to the space center after the success of Chandrayaan-3.

“When he was talking, he was a bit emotional, thanking all of us for our efforts and appreciating everyone’s contributions. He was very clear that we need to involve other government agencies in space activities, which eventually led to the space sector reforms,” Sankaran said while speaking to ANI.

Following the successful landing of Chandrayaan-3, PM Modi declared August 23 as National Space Day and named the landing site ‘Shiva Shakti Point,’ while designating the Chandrayaan-2 landing site as ‘Tiranga Point.’

This historic achievement made India the fourth country to land a rover on the Moon and the first to do so in the Moon’s southern polar region. The celebration aims to inspire future generations and foster interest in space exploration across the nation.

The theme for National Space Day 2024 is “Touching Lives while Touching the Moon: India’s Space Saga,” reflecting the impact of space achievements on everyday life and the nation’s ambitious space endeavors.

The feat has been achieved entirely through indigenous design and development.

The world’s first rocket with a single piece 3D printed engine was launched from Sriharikota on Thursday by Agnikul Cosmos, the IITMadras-incubated start-up.

The launch was witnessed by various luminaries including Dr S Somanath, Chairman, Indian Space Research Organisation (ISRO), Dr Pawan Goenka, Chairman of IN-SPACe, Rajeev Jyoti, Director (Technical), IN-SPACe, and A Raj Rajan, Director SHAR.

The ISRO chairman said that the success involving many firsts, including the 3D printed semi-cryogenic engine, flight control systems etc. demonstrate the prowess of indigenous design and innovation. “It motivates ISRO to support the Space startups and non-governmental entities for innovation and Atmanirbharata to create a vibrant space ecosystem in the country,” he said.

The feat has been achieved entirely through indigenous design and development after the launch was postponed many a times. ‘Agnibaan – SOrTeD’ Sub-Orbital Technology Demonstrator also has the unique distinction of having been launched from India’s first private launch pad called ‘Dhanush’ established by Agnikul. It is also India’s first semi-cryogenic engine-powered rocket launch.

“The key purpose of this mission, which is also Agnikul’s first flight, is to serve as a test flight, to demonstrate the in-house and home grown technologies, gather crucial flight data and ensure optimal functioning of systems for Agnikul’s orbital launch vehicle, the ‘Agnibaan’,” a statement issued by the company said.

The Agnibaan SOrTeD is powered by a semi-cryogenic engine that uses commercially available aviation turbine fuel or essentially kerosene and medical grade liquid oxygen, according to the company. Agnikul follows up on the first launch made by an Indian space company which was Skyroot Aerospace Private Limited which in 2022 flew a solid fuelled sounding rocket from Sriharikota.

Speaking about the next steps, Prof Satyanarayanan R Chakravarthy, founding advisor, Agnikul Cosmos and also the Head of National Centre for Combustion Research and Development (NCCRD), IIT Madras, said, “We are proud to present India’s first Semi-cryo rocket engine, which is also the world’s most integrated single shot 3D printed piece. It signals the ability to rapidly assemble rockets that is unparalleled.”

The Agnikul team consists of over 200 engineers and is associated with NCCRD at IIT Madras. Additionally, the team is guided by 45 former scientists from ISRO who bring invaluable expertise to the endeavour of democratising access to space, a statement said.

The flagship launch vehicle, ‘Agnibaan’, is designed to be compatible with the mobile launchpad called ‘Dhanush,’ allowing for launch flexibility regardless of location. Agnibaan can be configured to accommodate payloads ranging from 30 kg to 300 kg, ensuring versatility across a wide range of mission requirements, the statement added. The startup is aiming to fly an orbital mission towards the end 2024-2025.

GLOBAL: SPACE / MOON LANDING: Chandrayaan 3’s landing site name ‘Shiv Shakti’ gets International Astronomical Union (IAU) recognition

Chandrayaan 3’s moon lander’s landing site was named Shiv Shakti on August 26 by Prime Minsiter Narendra Modi.

Prime Minister Narendra Modi on August 26 had announced that the landing site of Chandrayaan 3’s moon lander would be named Shiv Shakti. Six months later, the internationally recognised body for nomenclature of celestial objects has officially granted it recognition.

International Astronomical Union (IAU) Working Group for Planetary System Nomenclature on Tuesday approved the name ‘Statio Shiv Shakti’ for the landing site of Chandrayaan’s Vikram lander.

Chandrayaan 3 — India’s moonshot

Chandrayaan 3, India’s third lunar mission, took off from the Indian Space Research Organisation (ISRO) Satish Dhawan Space Centre in Sriharikota on July 14. After about a month, on August 23, the Vikram lander successfully touched down on the moon, along with the Pragyan Rover. This historic achievement positioned India as the first country to land near the lunar South Pole and only the fourth to achieve a controlled lunar landing.

Following 10 days of exploration on the lunar surface, both the lander and rover entered sleep mode. Meanwhile, the propulsion module remains in lunar orbit after separating from the lander.

What is Shiv Shakti point?

On August 26, PM Narendra Modi declared that the landing site of Chandrayaan 3’s moon lander would be named Shiv Shakti .

“In Shiv, there is a resolution for the welfare of humanity, and Shakti gives us strength to fulfil those resolutions,” said Modi, while announcing the name.

The IAU’s Gazetteer of Planetary Nomenclature, where the name was officially published, described it as a compound word from Indian mythology representing the masculine (“Shiva”) and feminine (“Shakti”) duality of nature.

Why are celestial bodies named?

Planetary nomenclature is like naming places on Earth. It helps us identify and talk about specific features on planets and moons. This list, created by the International Astronomical Union (IAU), includes all the names given to different spots on planets, moons, and even some ring systems since 1919. It makes it easier for scientists to locate and describe these places.

GLOBAL: SATELLITES & SPACE: The Indian Space Research Organisation (ISRO) Successfully Launches 36 Satellites for UK-based OneWeb

This batch of 36 satellites by the UK-based OneWeb will be its 18th launch to date, its third this year and the second with ISRO.

The Indian Space Research Organisation (ISRO) on Sunday successfully launched the second batch of 36 satellites for the UK-based OneWeb.

“We have lift off! Thanks to our colleagues at @isro and @NSIL_India for a successful launch. If you don’t already, make sure to follow us for more updates throughout the rest of the mission,” OneWeb tweeted at 9.04am on Sunday.

This batch of satellites by the UK-based company will be its 18th launch to date, its third this year and the second with ISRO. This will also complete the company’s first-generation LEO (low earth orbit) constellation, enabling the company to initiate global coverage in 2023.

HT on March 6 reported about ISRO’s plan to launch the second batch of OneWeb’s satellites on March 26.

On February 16, these 36 satellites reached India from the US for their launch. On March 15, the satellites were also encapsulated.

The communications satellites were launched by ISRO’s Launch Vehicle Mark-III (LVM3). In October last year, the Indian space agency successfully launched the first set of 36 satellites by OneWeb from the Satish Dhawan Space Centre in Sriharikota, marking the rocket’s entry into the global commercial launch service market.

A week after that, ISRO successfully conducted the flight acceptance hot test of the CE-20 engine in the high-altitude test facility of its propulsion complex at Tamil Nadu’s Mahendragiri for 25 seconds for the second batch of satellites that are expected to be placed on low earth orbit.

After its first launch, OneWeb had said that its partnership with NSIL and ISRO demonstrated its commitment to provide connectivity across the length and breadth of India by 2023.

ISRO’s LVM3 rocket is capable of launching four-tonne class of satellites to geosynchronous transfer orbit. It is a three-stage vehicle with two solid motor strapons, a liquid propellant core stage and a cryogenic stage. The OneWeb satellites will be placed in orbit at an altitude of 1,200km above the earth’s surface.

“This mission marks OneWeb’s second satellite deployment from India, highlighting the collaboration between the UK and Indian space industries. Across India, OneWeb will bring secured solutions not only to enterprises but also to towns, villages, municipalities and schools, including the hardest-to-reach areas across the country,” the company said last week.

NATIONAL: SPACE / SATELLITES &TECHNOLOGY: ISRO Successfully Launches SSLV’s 2nd Developmental Flight with 3 Satellites from Sriharikota

The new rocket launch from Sriharikota has put three satellites into a 450 km-circular orbit during its 15-minute flight .

The Indian Space Research Organisation (ISRO) successfully launched its second developmental flight of a Small Satellite Launch Vehicle — SSLV-D2 — and placed three satellites in its precise orbit on February 10 morning.

The three satellites are ISRO’s Earth Observation Satellite – EOS 07, U.S.-based firm Antaris’ Janus-1 and Chennai-based space start-up SpaceKidz’s AzaadiSAT-2. 

SSLV-D2 lifted off from the first launch pad at Satish Dhawan Space Centre-SHAR, Sriharikota at 9:18 a.m. This is the first satellite launch in 2023.

“The SSLV-D2-EOS-07 mission is successfully accomplished,” ISRO mentioned on its Twitter handle, a few minutes after the vehicle took off. ISRO in a statement said: “The vehicle injected satellites into close to 450 km circular orbit at an inclination of 37.2 degrees. The tracking network took control of EOS-07 satellite. Deployment of the solar panels and the generation of power is confirmed.”

ISRO Chairman S. Somanath said, “In its second attempt SSLV-D2 has placed the EOS-07 satellite in its intended orbit very accurately. Two more satellites -Janus-1 and AzaadiSAT-2 were also placed in the required orbit.”

The Chairman further said: “SSLV had its maiden flight SSLV-D1 and we had a narrow miss of placing the satellite in the orbit because of a shortfall in velocity. I’m happy to report that we have analysed the problems faced in SSLV D1 – identified the corrective actions and implemented it. We went through lot of studies to ensure that the vehicle will become success this time,” he added. 

“And I’m happy this has been executed in reality. The orbit achieved by the vehicle today is exceedingly good,” Mr. Somanath said.

Noting that this journey began in 2018, S.S. Vinod, Mission Director of SSLV, said, “We had the maiden flight in August 2022 and we could not place the satellite in the intended orbit. Post that detailed analysis with a number of teams was carried out and we were able to pinpoint the problem in the system . We overcame that.”

He added, “And in a period of five months we have come back. And we will be coming back soon with the next launch of SSLV.”

It may be recalled that the first developmental flight of SSLV lifted off from Satish Dhawan Space Centre on August 7, 2022, and ended up to be a partial failure, as the rocket failed to inject its satellite payload in their intended orbits.

According to ISRO, the spacecraft was injected into a highly elliptical unstable orbit due to a shortfall in velocity, leading to their decay and deorbiting immediately, in spite of the normal performance of all solid propulsion stages. 

Subsequent detailed analysis of the flight events and observations ranging from the countdown, lift-off, propulsion performance, stage separations and satellite injection revealed that there was a vibration disturbance for a short duration on the Equipment Bay (EB) deck during the second stage (SS2) separation. This affected the Inertial Navigation System (INS), resulting in declaring the sensors faulty by the logic in Fault Detection and Isolation (FDI) software.

About SSLV-D2

EOS-07 is a 156.3 kg satellite designed, developed and realized by ISRO. The mission objective of EOS-07 is to design and develop payload instruments compatible with microsatellite bus and new technologies, which are required for future operational satellites. Moreover, it will also design and develop a microsatellite accommodating new technology payloads in a quick turn-around time. 

New experiments include mm-Wave Humidity Sounder and Spectrum Monitoring Payload. Weighing around 10.2 kg, Janus-1 is a technology demonstrator, smart satellite mission based on the Antaris software platform. An 8.7 kg satellite AzaadiSAT-2 is a combined effort of about 750 girl students across India guided by Space Kidz India, Chennai.

According to details provided by ISRO, SSLV caters to the launch of up to 500 kg satellites to Low Earth Orbits on a “launch-on-demand” basis. It provides low-cost access to space, offers low turn-around time and flexibility in accommodating multiple satellites, and demands minimal launch infrastructure. It is configured with three solid propulsion stages and a velocity terminal module. It is a 34 m tall, 2 m diameter vehicle having a lift-off mass of 120 tonnes.

NATIONAL: SCIENCE & TECHNOLOGY / DEFENCE / AEROSPACE: ISRO’s Vikram Sarabhai Space Centre carries out Parachute Airdrop test of Gaganyaan Human Spaceflight programme

The Gaganyaan deceleration system consists of three main parachutes, besides the smaller ACS, pilot, and drogue parachutes, to reduce the speed of the crew module to safe levels during its landing.

ISRO’s Vikram Sarabhai Space Centre has conducted the Integrated Main Parachute Airdrop Test (IMAT) of its crew module deceleration system for the much-awaited maiden Gaganyaan human spaceflight programme at the Babina Field Fire Range (BFFR) in Jhansi district of Uttar Pradesh.

The IMAT conducted on Friday marks a significant milestone toward realising the nation’s ambitious Gaganyaan project, the Indian Space Research Organisation (ISRO) said in a statement.

The Gaganyaan deceleration system consists of three main parachutes, besides the smaller ACS, pilot, and drogue parachutes, to reduce the speed of the crew module to safe levels during its landing, the space agency said.

Two of the three main chutes are sufficient to land the astronauts on earth, and the third is redundant, ISRO said adding that the IMAT test simulated the case when one main chute failed to open.

The IMAT test is the first in a series of integrated parachute airdrop tests planned to simulate different failure conditions of the parachute system before it is deemed qualified to be used in the first human spaceflight mission.

In this test, a five-tonne dummy mass, equivalent to the crew module mass, was taken to an altitude of 2.5 kilometres and dropped using the Indian Air Force’s IL-76 aircraft. Two small pyro-based mortar-deployed pilot parachutes then pulled the main parachutes.

The main parachute sizes were initially restricted to a smaller area to reduce the opening shock. After seven seconds, the pyro-based reefing line cutters cut the area restricting line, allowing the parachutes to inflate fully.

“The fully inflated main parachutes reduced the payload speed to a safe landing speed. The entire sequence lasted about 2-3 minutes as the scientists watched the different phases of the deployment sequence unfold with bated breath. There was loud cheer and applause as the payload mass landed softly on the ground and the gigantic parachutes collapsed,” the statement read.

The design and development of the parachute-based deceleration system is a joint venture of ISRO and the Defence Research and Development Organisation (DRDO).

“The overall system design, analytical simulations of parachute deployment and crew module descent under various conditions, the design and development of ordnance devices for parachute extraction and ejection, assembly, mechanical and electrical integration of deceleration system, it’s instrumentation and avionics for conducting this drop tests are done at ISRO’s leading Research and Development centre, Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram,” the space agency explained.

Senior ISRO and DRDO scientists and airforce officers were present when the crucial test was done.

“Besides proving the calibre of the scientists of ISRO and DRDO, the test also demonstrated the active coordination between the country’s premier agencies, namely ISRO, DRDO, the Indian Air Force, and the Indian Army,” ISRO said quoting a senior official.

The heaviest rocket of the Indian Space Research Organisation– LVM3-M2/OneWeb India-1 blasted off from this spaceport on Sunday to place 36 broadband communication satellites into the Low Earth Orbit (LEO) for a UK-based customer.

NewSpace India Limited (NSIL), a central public sector enterprise under the Department of Space, had earlier signed two launch service contracts with the London-headquartered Network Access Associated Limited (OneWeb) for launching OneWeb LEO satellites on board ISRO’s LVM3.

OneWeb is a private satellite communications company, in which India’s Bharti Enterprises is a major investor and shareholder.

On Sunday, the 43.5 metre tall rocket soared majestically at 12.07 am from the second launch pad at the Satish Dhawan Space Centre here at the end of the 24-hour countdown.

The vehicle is also dubbed as one of the heaviest for its ability to carry satellites upto 8,000 kg.

The mission assumes significance as this was LVM3’s maiden commercial mission and also NSIL’s first with the said launch vehicle.

According to ISRO, the mission has the heaviest payloads with 36 satellites of OneWeb, becoming the first Indian rocket with a payload of 5,796 kg.

The launch is also first for LVM3-M2 to place the satellites in the Low Earth Orbit (up to 1,200 kms above the earth) unlike Geosynchronous Transfer Orbit (GTO).

ISRO scientists have rechristened the launch vehicle its present name from GSLV-MKK III as the newest rocket is capable of launching 4,000 kilogram class of satellites into GTO and 8,000 kgs of payloads into LEO.

GSLV-Mk III had four successful missions in the past. LVM3-M2 is a three-stage launch vehicle consisting of two solid propellant S200 strap-ons on its sides and core stage comprising L110 liquid stage and C25 cryogenic stage.

OneWeb Ltd is a global communication network powered from space, enabling internet connectivity for governments and businesses.
