  • BullSequana will be set up in India under the National Supercomputing Mission (NSM).

2.2. Challenges to Supercomputing in India:

  • Limited funding: Limited investments and delayed release of funds have held India back. Even after launching NSM, only 10 per cent of its total budget has been released at the end of three years.

  • Hardware development: India’s stronghold is in software development, it has to depend on imports to procure the hardware components required for building supercomputers. Cutting edge technology in hardware components is difficult to procure as supercomputing is a niche field. Even a large part of BullSequana will only be assembled in India.

  • Brain Drain: Large Multi-National Corporations (like Google) have also entered the supercomputing field. Competing with such MNCs to retain talent for developing and maintaining supercomputers proves difficult for Government.

  • Actual chip design and manufacturing is difficult to achieve (due to many factors like high initial investment needed, limited availability of rare earth metals). However, India has software skills and personnel base which can be effectively leveraged to propel innovation on the software components of supercomputer technology. Also, Exascale system, which is now used in supercomputers, may reach its speed barrier soon. Thus, India could focus its research on new approaches like Quantum Computing and Optical Computing.

4. Visions-2 Mission

More about VISIONS-2

Sounding Rocket (Probe Rockets)

  • It makes brief, targeted flights into space before falling back to Earth just a few minutes later which is designed to probe atmospheric conditions and structure at heights (80–160 km) during its sub optimal flight.

 

Aurora Borealis

  • The auroras are formed when energetic electrons, accelerated in the electric and magnetic fields from sun in near-Earth space, crash into and excite atmospheric gases, which emit bright hues of red, green, and yellow as they relax back to a lower energy state.

  • The lights are seen above the magnetic poles of the northern and southern hemispheres. They are known as 'Aurora borealis' in the north and 'Aurora Australis' in the south.

 

Polar Cusps

  • At almost any location near the surface of the magnetopause, the Earth's magnetic field provides a natural barrier to the solar wind particles. However, there are two regions, located above each pole, where solar wind particles have a direct access to the Earth's ionosphere. These regions are known as the polar cusp.

  • It is a sounding rocket mission to get a closer look at the how the Earth’s atmosphere is slowly leaking into space.

  • The Earth is losing weight as observations show that several hundred tons of atmosphere is getting “leaked” into space every day.

  • The aurora borealis is of keen interest to the VISIONS-2 team as they are fundamental drivers in the process of atmospheric escape.

  • Scientists had long thought that oxygen was too heavy to escape Earth's gravity. But near-Earth space has much more Earth-borne oxygen than anyone had expected. This is as a result of processes that energize the oxygen enough to escape. The aurora is one such process.

  • It is the first of nine sounding rockets launching over the next 14 months as part of the Grand Challenge Initiative - cusp, an international collaboration to explore the unusual portal between Earth and space.

  • Importance: Understanding atmospheric escape on Earth has applications all over the Universe – from predicting which far off planets might be habitable, to understanding how Mars became a desolate and exposed landscape.

5. Soyuz

International Space Station (ISS)

  • ISS is a space station, or a habitable artificial satellite, in low Earth orbit.

  • Its first component was launched into orbit in 1998, with the first long-term residents arriving in November 2000. The Station is expected to operate till 2030.

  • It is the largest human-made body in low Earth orbit and can often be seen with the naked eye from Earth.

  • It serves as a microgravity and space environment research laboratory.

  • It is a joint project among five participating space agencies: NASA (USA), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).

  • China launched its first experimental space station, Tiangong 1, in September 2011.

5.1. About Soyuz

  • The Soyuz is a Russian spacecraft which carries people and supplies to and from the space station.

  • It has room for three people to ride in it. The spacecraft also brings food and water to the space station.

  • It is like a lifeboat. At least one Soyuz is always attached to the space station. If there were an emergency on the space station, the crew could use the Soyuz to leave the space station and return to Earth.

  • Currently only this Russian spacecraft carry people to ISS after USA retired its space shuttle in 2011.

6. Sunspot Cycle

What is Sun-spot Cycle?

  • The amount of magnetic flux that rises up to the Sun's surface varies with time in a cycle called the solar cycle. This cycle lasts 11 years on average. This cycle is referred to as the sunspot cycle.

  • They are darker, magnetically strong, cooler areas on the surface of the sun in a region called the photosphere.

 

Why this is important?

  • It will help in understanding of the long-term variations of the Sun and its impact on earth climate which is one of the objectives of India’s first solar probe – ‘Aditya L-1 Mission’.

  • The forecast will be also useful for scientific operational planning of the Aditya mission

 

How does Sunspot Cycle affect the Earth?

  • An important reason to understand sunspots is that they affect space weather.

  • During extreme events, space weather can affect electronics-driven satellite controls, communications systems, air traffic over polar routes and even power grids.

  • Some believe that they are correlated with climate on earth. For instance, during past periods of low sunspot activity, some parts of Europe and North America experienced lower-than-average temperatures.

7. Telerobotic Surgery

Tele-robotics Applications

  • Space: Most space exploration has been conducted with telerobotic space probes.

  • Telepresence and videoconferencing: The prevalence of high-quality video conferencing has enabled a drastic growth in telepresence robots to help give a better sense of remote physical presence for communication.

  • Marine applications: Marine remotely operated vehicles (ROVs) are widely used to work in water too deep or too dangerous for divers. They repair offshore oil platforms and attach cables to sunken ships to hoist them. They are usually attached by a tether to a control center on a surface ship.

  • India became the world's first to successfully perform a telerobotic coronary intervention.

 

What is telerobotic coronary intervention?

  • It is a robotic method of performing heart surgery. With the help of the internet and a robotic tower, a surgeon is able to treat patients from a distance.

  • This technology is especially important for high emergency situations of heart attacks and stroke, where ideal treatment must be received within 90 minutes or 24 hours.

  • This platform has the potential to improve patient access in rural & under-served populations and reduce treatment time, benefitting those groups, who have geographical barriers and low socio-economic status.

  • It will also reduce the variability in operator skills and improve clinical outcomes.

8.2. Medical Devices Industry (MDI) in India

  • MDI plays a key role in the healthcare ecosystem and “is indispensable in achieving the goal of health for all citizens of the country. However, the medical device market is dominated by imported products, which comprise of around 80% of total sales. The domestic companies are largely involved in manufacturing low-end products for local and international consumption.

  • Opportunity: Given the higher disposable incomes in the country, increasing public spending in healthcare (higher penetration of health insurance), improving medical tourism along with luxury healthcare markets and increasing FDI in the sector, India presents an important opportunity for medical device industry both domestically and internationally.

  • Challenges: Along with numerous opportunities, the market faces various challenges in terms of presence of multiple regulators, archaic laws (which do not permit manufactures and importers of medical device to promote their product directly to the customer), weakening rupee (making it difficult for some medical device importers to promote their product directly to the consumers), and government’s price control (e.g. stent capping).
