Chandrayaan 2: The Sun has finally set on Vikram lander

The sun has finally set on Vikram lander as the 14 day window to establish connection with it ended on September 20.

The two-week period saw heavy scouting for the lander from the Indian Space Research Organisation (ISRO). From the early morning of September 7, when the lander failed to soft land, till last Friday, the space agency had been trying to establish connection with the lander with little to no success.

“We know it is highly unlikely to connect with the lander. There are way too many conditions, but we will continue to try till September 20, the last window to establish contact,” said an ISRO scientist, who was a part of the tracking team.

The space agency was hopeful to establish connection as Vikram was spotted a day after the hard landing

However, ISRO's cryptic tweet on Wednesday made it certain that it had given up on Vikram.

Indian Space Research Organisation in a tweet last Friday said that the agency has set up a national committee of academicians and ISRO experts to analyse the cause of loss of communication with the lander.

Though results of the analysis are awaited, informed guesses have been made as to what could have happened. The most reasonable one, at this juncture, seems to be the speed of the lander. Nonetheless, the exact landing speed of Vikram is still unknown. Experts say it could have certainly played a factor.

An Outlook report stated that changes in mission profile from the original plan could also have led to the failure. It includes change in the satellite carrier from GSLV Mk II to GSLV Mk III. Also the lander had five engines and was programmed to soft land. The article states that originally the lander was supposed to drop down slowly after its four throttle engines were switched off.

Apparently fifth engine was introduced later and hence there was a software change. “How well it was tested, it is not known,” the article quoted a former ISRO scientist.

Similar to all failures, the Vikram landing too raised question over the point of such expensive missions, especially at a time when the economy is in such a dire state. The cost of mission was reported to be Rs 1000 crore, which could have been used for other welfare schemes, critics argued.

The next ISRO mission - Gaganyaan - is touted to cost Rs 10,000 crore, which could be a feather in the cap of the space agency but will be expensive nonetheless.

But is that the right way to think about it? It sure is a tough question to answer.

For the optimist, investment in science and technology ensures that we are future-ready, even though the benefits are not usually visible in short term. For instance, without such investments the US and China will not be where they are right now. This would automatically mean that failures are part and parcel of such experiments.

Chandrayaan 2 was one too.

What are we getting from the failure? Mastering technologies that will put us on par with developed nations and even build cost effective technologies that other countries can emulate. There goes your business aspect of the space tech.

There is another important aspect. In an earlier conversation with Moneycontrol, M Annadurai, an ISRO scientist and project director of Chandrayaan-1 pointed out these missions are necessary to stop the brain drain from India.

Before such missions were conceptualised, ISRO’s attrition rate was at an all time high and bright scientists were moving into IT and overseas in search of tougher challenges. For a vacancy of 200, applications were in thousands.

That all changed when Chandrayaan-1 came into picture. “After that attrition was almost nil,” Annadurai said. There are at least one lakh applications for the same 200 vacancies now.

To retain the brightest of minds, the agency needs to create aspirational value. For that you need to build such mission that would interest and challenge the brightest minds in the country.

For, it is these brightest of minds that is the need of the hour for India, which is aiming for $5 trillion in the coming years.

Pakistan committed one of the biggest blunders by joining U.S. after 9/11, says Imran Khan

Pakistan committed one of the biggest blunders by joining U.S. after 9/11, says Imran Khan Pakistan . Prime Minister Imran Khan admitted on September 24 that Pakistan committed “one of the biggest blunders” by joining the U.S. after the 9/11 attacks, saying the previous governments “should not have pledged what they could not deliver”. Speaking at the Council on Foreign Relations (CFR) think-tank here, Mr. Khan also said the least he expects the international community to do is to urge India to lift the curfew in Kashmir. Responding to a question, Mr. Khan said he had urged his Indian counterpart Narendra Modi to “reset” bilateral ties and his government waited to resume talks until after the elections in India were over but then it found that “India is pushing us in the blacklist of the Financial Action Task Force to bankrupt us”. He said that by abrogating Article 370, India had cast aside the UN Security Council resolutions, the Simla accord and its ...

Science, Tech, Math › Science Laws of Thermodynamics as Related to Biology Share Flipboard Email Energy and Thermodynamics Mikael Häggström/Public Domain by Regina Bailey Updated July 09, 2019 The laws of thermodynamics are important unifying principles of biology. These principles govern the chemical processes (metabolism) in all biological organisms. The First Law of Thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed. It may change from one form to another, but the energy in a closed system remains constant. The Second Law of Thermodynamics states that when energy is transferred, there will be less energy available at the end of the transfer process than at the beginning. Due to entropy, which is the measure of disorder in a closed system, all of the available energy will not be useful to the organism. Entropy increases as energy is transferred. In addition to the laws of thermodynamics, the cell theory, gene theory, evolution, and homeostasis form the basic principles that are the foundation for the study of life. First Law of Thermodynamics in Biological Systems All biological organisms require energy to survive. In a closed system, such as the universe, this energy is not consumed but transformed from one form to another. Cells, for example, perform a number of important processes. These processes require energy. In photosynthesis, the energy is supplied by the sun. Light energy is absorbed by cells in plant leaves and converted to chemical energy. The chemical energy is stored in the form of glucose, which is used to form complex carbohydrates necessary to build plant mass. The energy stored in glucose can also be released through cellular respiration. This process allows plant and animal organisms to access the energy stored in carbohydrates, lipids, and other macromolecules through the production of ATP. This energy is needed to perform cell functions such as DNA replication, mitosis, meiosis, cell movement, endocytosis, exocytosis, and apoptosis. Second Law of Thermodynamics in Biological Systems As with other biological processes, the transfer of energy is not 100 percent efficient. In photosynthesis, for example, not all of the light energy is absorbed by the plant. Some energy is reflected and some is lost as heat. The loss of energy to the surrounding environment results in an increase of disorder or entropy. Unlike plants and other photosynthetic organisms, animals cannot generate energy directly from the sunlight. They must consume plants or other animal organisms for energy. The higher up an organism is on the food chain, the less available energy it receives from its food sources. Much of this energy is lost during metabolic processes performed by the producers and primary consumers that are eaten. Therefore, much less energy is available for organisms at higher trophic levels. (Trophic levels are groups that help ecologists understand the specific role of all living things in the ecosystem.) The lower the available energy, the less number of organisms can be supported. This is why there are more producers than consumers in an ecosystem. Living systems require constant energy input to maintain their highly ordered state. Cells, for example, are highly ordered and have low entropy. In the process of maintaining this order, some energy is lost to the surroundings or transformed. So while cells are ordered, the processes performed to maintain that order result in an increase in entropy in the cell's/organism's surroundings. The transfer of energy causes entropy in the universe to increase.
