ISRO successfully launches SSLV’s second developmental flight with three 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.

Telangana teen researcher wins international award for developing organic insecticide

The extract of Ramphal leaves is effective against various insect and pests like, pod borer, Helicoverpa armigera, fall armyworm, spodoptera frugiperda, larvae, and green peach aphids.

Sarvesh Prabhu, a 17-year-old research intern at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), represented India at the International Science and Engineering Fair in Atlanta, USA and won the third prize in the biochemistry category. He was awarded $1,000 for developing a cost-effective bio-insecticide from the leaves of bullock’s heart, Annona reticulata, popularly known as Ramphal.

When asked what led him to such a discovery, he said, “During the lockdown, my sister did gardening as a hobby. All of our plants were getting eaten by insects before they could grow, resulting in a terrible harvest. While my sister wanted to use chemical insecticides, I was absolutely against them, which led me to find botanical insecticides as an alternative. Ramphal grows in our garden, and we noticed that it flourished when all other plants were struck by pests. Thus, began my project in the middle of the pandemic.”

The extract of Ramphal leaves is effective against various insects and pests like pod borer, Helicoverpa armigera, fall armyworm, Spodoptera frugiperda, larvae, and green peach aphids. Ramphal leaves were tested in a lab. The results showed a mortality range of 78-88 per cent.

He said, “One of my main goals was to make it cost-effective and easy to manufacture by the farmer themselves. The preparation process of the insecticide is simple and easy. The Ramphal tree is also commonly found across India. This botanical product is several times cheaper than most insecticides in the market.”

About winning the prestigious prize, he said, “It was truly a pursuit that I cannot forget. More than the prize, the journey was impactful. The friends I made, the knowledge I gained from previous research papers, and the skills I acquired from the experts at ICRISAT are invaluable.”

Hetero’s COVID-19 oral drug Nirmacom gets WHO prequalification

WHO made a strong recommendation for Nirmatrelvir and Ritonavir for mild and moderate COVID-19 patients at highest risk of hospital admission.

Pharmaceutical company Hetero on December 26 said it has received World Health Organization Prequalification of Medicines Programme (WHO PQ) approval for its generic version of Covid-19 oral antiviral treatment candidate nirmatrelvir.

Nirmatrelvir, which originated in Pfizer laboratories, is co-packaged with ritonavir tablets as Pfizer’s Covid-19 oral antiviral drug Paxlovid. This is the first prequalification for a generic version of Paxlovid, Hetero said.

The combi pack launched by Hetero as Nirmacom will contain nirmatrelvir 150 mg (two tablets) and ritonavir 100 mg (one tablet). A prescription only drug that the company said be initiated as soon as possible after diagnosis of Covid-19 and within five days of symptom onset, Nirmacom is be manufactured at Hetero’s facilities in the country.

WHO had made a strong recommendation for nirmatrelvir and ritonavir for mild and moderate Covid-19 patients at highest risk of hospital admission, such as unvaccinated, aged or immunosuppressed patients, Hetero said in a release.

Managing Director of Hetero Group of Companies Vamsi Krishna Bandi said WHO prequalification for Nirmacom is a significant milestone and the company is committed to making the drug available faster at affordable prices across 95 low and medium income countries, including India. Hetero was among a clutch of companies that entered into a non-exclusive voluntary licensing agreement with Medicines Patent Pool (MPP) for manufacturing and sale of a generic version of Pfizer’s nirmatrelvir in LMICs.

“Delighted to see the first generic version of nirmatrelvir under MPP license with Pfizer receive quality assurance approval from WHO. This is an impressive achievement from Hetero as we announced the sublicence agreements just nine months ago,” MPP Executive Director Charles Gore said.

Hetero has already received emergency use authorisation (EUA) approval from the Drugs Controller General of India (DCGI) to manufacture and market Nirmacom.

Global award for RGCB scientist for study on pathogens

She has been working on the human pathogens Chlamydia trachomatis. Her research focuses on how these pathogens evade the host immune system.

Dr. Karthika Rajeeve, staff scientist at the Rajiv Gandhi Centre for Biotechnology (RGCB), has been selected for the Ben Barres Spotlight Award, 2022.

The Ben Barres Spotlight Awards has been instituted by scientific journal eLife to perpetuate the memory of American neurobiologist Dr. Ben Barres, a transgender researcher who advocated equality in science.

Dr. Karthika is one of the 12 scientists from around the world chosen for the prestigious award this year. She has been working on the human pathogens Chlamydia trachomatis. Her research focuses on how these pathogens evade the host immune system.

“The scientific community at RGCB is elated at the international recognition received by Dr. Karthika Rajeeve,” said Professor Chandrabhas Narayana, Director RGCB.

Money for equipment

Dr. Karthika said she would use the award to buy much-needed equipment to take forward her research, besides attending an international conference on Chlamydia biologists to increase the visibility of her work.

Chlamydia trachomatis (Ctr) is a neglected tropical disease and the infection remains asymptomatic as a silent epidemic. The bacteria persist over extended times within their host cell and thereby establish chronic infections.

Persistent and chronic infection can cause potentially fatal ectopic (outside the uterus) pregnancy, pelvic inflammatory disease and sterility.

Her study challenges a long-standing hypothesis and shows that interferon gamma can down regulate c-Myc, the key regulator of metabolism leading to chlamydial persistence.

Fifth Scorpène-class submarine Vagir delivered to Navy

It is scheduled to be commissioned into service in January.

The fifth Scorpène-class conventional submarine, Vagir, was delivered to the Navy by Mazagon Dock Shipbuilders Limited (MDL) Mumbai on December 20. It is scheduled to be commissioned into service next month, a Navy official said.

“It is a matter of great pride that Vagir has completed all major trials including the weapon and sensor trials in the shortest time in comparison to the earlier submarines,” the Navy said in a statement. A notable achievement is that this is the third submarine delivered to the Navy in a span of 24 months, it added.

Vagir was launched into water on November 12, 2020 and commenced sea trials on February 1, 2022.

The sixth and last of the Scorpène-class submarines, Vagsheer, was launched into water in April 2022 and is expected to be delivered to the Navy by end 2023.

Six Scorpene submarines are being built under Project-75 by MDL under technology transfer from Naval Group of France under a $3.75 billion deal signed in October 2005. The project is about four years behind schedule.

The first submarine INS Kalvari was commissioned in December 2017, second submarine INS Khanderi in September 2019, third one INS Karanj in March 2021 and the fourth one INS Vela joined service in November 2021.

Parallelly, the tender to build six more advanced conventional submarines under Project-75I is in the Request For Proposal (RFP) stage but has suffered delays.

With delays in submarine induction, the SSKs – 209s (German HDWs) and EKMs (Russian Kilo’s), are being put through the Medium Refit Life Certification (MRLC) process which will give them additional life of 10 to 15 years.

The Navy currently has 15 conventional and one nuclear submarine in service. It includes seven Russian Kilo class submarines, four German HDW submarines, four Scorpene class submarines and the indigenous nuclear ballistic missile submarine INS Arihant.

The Navy has drawn up plans to install Air Independent Propulsion (AIP) modules on all Scorpene submarines as they go for their refit beginning with INS Kalvari in the next couple of years to enhance their endurance. Development of an indigenous AIP module developed by the Defence Research and Development Organisation (DRDO) is in advanced stages.

World Ayurveda Congress: Experts pitch for innovations and research in Ayurveda

Anirudha Joshi said he was envisaging developing wearable devices that could provide vital information about anatomy.

Ayurveda has an enormous potential for innovation but that requires an extensive technology-based research and a concrete roadmap to make it a global brand and its products effective and successful, said experts at the 9th World Ayurveda Congress (WAC) here.

“There are great possibilities of innovations in Ayurveda. There are challenges to develop techniques more advanced than supercomputers. We will have to work on those areas of computing which have not been heard of,” Padma Bhushan Vijay Bhatkar said, while chairing a plenary session on ‘Innovation and Entrepreneurs in Ayurveda’.

Anirudha Joshi, who is credited with developing award-winning ‘Nadi Tarangini’, an Artificial Intelligence-based instrument for pulse-reading, said he was envisaging developing wearable devices that could provide vital information about the human body.

“It will be very helpful if we can develop wearables which can do ‘Astha-vidha-pariksha’. Our vision is to go into prediction of different stages of a disease so that we can defer a disease if we cannot prevent it,” he explained.

In his concluding remarks, Mr. Bhatkar said, “There is a need to develop new devices like `Nadi Tarangini’. We will have to think of ways of marketing, packaging, advertising our products and how they can be shown to the world.’‘ According to Kartikeya Baldva, CEO, Ixoreal Biomed Inc, Ayurveda, a traditional wellness system, had finally arrived but there was still a long way to go.

“It is very important to ensure the success of products but that would require quality, efficacy, branding, marketing and innovation,” he emphasised.

Ajit Kolatkar, Founder- Director of Pune- based Gastrolab India Pvt Ltd, said Ayurveda had to move in such a fashion that a doctor could diagnose the ailments of a patient by using minimum devices.

”We will have to start with fundamental research from Ayurvedic perspective. There has to be a concrete roadmap. There is a need to revisit Ayurveda in the context of contemporary science,” he said, adding there were many key areas where Ayurveda could contribute significantly.

Rishabh Chopra, founder of Ayurveda Experience, an Ayurvedic health and wellness platform, said ‘Ashwagandha’ had now become a popular product in the West.

However, there were several challenges to make Ayurvedic products globally acceptable. He also said Ashwagandha, turmeric and Yoga were some of the most online searched words in the West.

India test-fires Agni-V ballistic missile having range of 5,000 km

The development comes amid lingering border row with China.

India on Thursday successfully test-fired nuclear-capable ballistic missile Agni-V that can strike targets at ranges up to 5,000 km, marking a significant boost to the country’s strategic deterrence, people familiar with the development said.

The test-firing of the missile from the APJ Abdul Kalam Island off Odisha coast came amid India’s lingering border row with China.

The Agni-V project is aimed at boosting India’s nuclear deterrence against China which is known to have missiles like Dongfeng-41 having ranges between 12,000-15,000 km.

Agni-V can bring almost the entire Asia including the northernmost part of China as well as some regions in Europe under its striking range.

The Agni 1 to 4 missiles have ranges from 700 km to 3,500 km and they have already been deployed.

The Agni-V missile has been successfully test-fired, two people familiar with the matter said.

There is no official word on the night trials of the missile.

The people cited above said the test validated a number of critical aspects of the weapon.

India carried out a similar test of the missile in October last year as well.

The successful test-firing of the missile paves way for its induction into the Strategic Forces Command that takes care of India’s strategic assets, the people cited above said.

The missile has a very high degree of accuracy to hit targets. It has a height of 17 metres and it is capable of carrying a 1.5-tonne warhead.

In June, India successfully carried out a night launch of the nuclear-capable Agni-4 ballistic missile, in a boost to India’s military capabilities.

Following the test, the Defence Ministry had said that it reaffirmed India’s policy of having a ‘credible minimum deterrence capability.” India has been steadily enhancing its overall military might in the last couple of years.

It has carried out successful tests of a number of missiles during the period.

In May, the extended range version of the BrahMos supersonic cruise missile was test-fired from a Sukhoi fighter jet.

It was the first launch of the extended range version of the BrahMos missile from a Su-30MKI aircraft.

An anti-ship version of the BrahMos supersonic cruise missile was successfully test-fired jointly by the Indian Navy and the Andaman and Nicobar Command in April.

Missile destroyer INS Mormugao commissioned into Indian Navy

Remarking that the state-of-the-art warship INS Mormugao was a major example of the country’s indigenous defense production capability, Defence Minister Rajnath Singh on December 18 expressed confidence about India being able to cater to not just local but global ship-building needs as well.

Mr. Singh was speaking at Mumbai’s Mazagaon docks during the Commissioning Ceremony of the INS Mormugao, the second of four ‘Visakhapatnam’-class destroyers (also classed as P-15B stealth, guided-missile destroyers) indigenously designed by the Indian Navy’s Warship Design Bureau.

The warship, christened after the historic port city in the coastal State of Goa, was built by the Mazagon Dock Shipbuilders Limited (MDSL).

Also present on the occasion were General Anil Chauhan, Chief of Defence Staff (CDS) of the Indian Armed Forces; Navy Chief Admiral R. Hari Kumar; Goa CM Pramod Sawant along with Goa Governor Sreedharan Pillai among others.

“The commissioning of this warship is proof of excellence in India’s warship design and development. The INS Mormugao is one of India’s strongest warships and I have full confidence that it will facilitate remarkable growth in country’s maritime capability. The ship will be among one of the world’s most technologically-advanced missile carrier and is a major example of our indigenous defence production capability. There is no doubt that in the near future, we will cater to India’s ship-building needs but that of the world’s as well,” said Mr. Singh, adding that the country was en-route to attaining the objective of not only ‘Make in India’ but ‘Make for World’.

The INS Mormugao is said to be equipped state-of-the-art weapons and sensors, surface-to-surface and surface-to-air missiles besides modern surveillance radar which provides target data to weapon systems. Capable of achieving speeds of over 30 knots, the warship is said to be able to fight under nuclear, biological and chemical warfare conditions.

Noting the continuous increase for demand in military equipment owing to global security reasons, the Defence Minister said that the country had every opportunity to utilise its capabilities to the fullest and move forward towards making India “an indigenous shipbuilding hub.”

Commenting on the name of the warship and the historic importance of Mormugao, Mr. Singh said: “Even as a port, Mormugao has contributed significantly to the growth of India’s maritime trade. Even today, it is one of the oldest and largest ports in the country and will retain this special place due to the services it provides…be it Mormugao fort or Mormugao port, both are recorded with great distinction in Indian history of India,” he said, noting the 17th century Maratha campaign against the Portuguese under Chhatrapati Sambhaji (Shivaji’s son).

The INS Mormugao was launched in September 2016 and commenced her sea trials on December 19, 2021, coinciding with 60 years of Goa’s Liberation from Portuguese rule. Her commissioning on today (December) coincides with the day that ‘Operation Vijay’ was launched in 1961 to free Goa from Portuguese rule.

Navy Chief, Admiral R. Hari Kumar said the achievement was “indicative of the large strides” the country had taken in warship design and building capability over the last decade, while stating that the Navy had a tradition of naming ships after cities which created an enduring umbilical link between the two.
