Before him Prince Sultan Bin Salman Abdulaziz Al Saud from Saudi Arabia and Muhammed Faris from Syria - have been to space. Both of their missions took place in the 1980s. On 25 September 2019 he launched aboard the Soyuz MS-15 spacecraft to the International Space Station accompanied by Oleg Skripochka of Russia and NASA astronaut Jessica Meir onboard. He will stay for eight days at International Space Station (ISS) doing scientific experiments with other international astronauts. The Mohammed Bin Rashid Space Center provided Al Mansoori with a 10kg bag, which includes important elements of Emirati heritage, culture and history, which will be placed in museums upon his return. As part of UAE’s space plans, the Arab nation has announced its aim to also become the first Arab country to send an unmanned probe to orbit Mars by 2021. The country has named its Mars mission as “Hope”. In the long-term, UAE also plans to build a “Science City” to replicate life on Mars. It also aims to create the first human settlement on red planet by 2117.
  • SoI:The Survey of India (SoI), which is country’s oldest department of central engineering agency for mapping and surveying the entire country, for the first time will deploy 300 drones for repairing unprecedented high resolution map of the country. It is affiliated to the Department of Science and Technology (DST). The aim is to map 75% of India’s geography— about 2.4 million sq km of the 3.2 million sq. km — within the next two years. Other than unprecedented detail, High-resolution maps will facilitate digitisation of land titles in villages. Currently the best SoI maps have a resolution of 1:250000, meaning a 1 cm on the map represent 2500 cm on the ground. The new maps being prepared will be of 1:500 resolution, meaning 1 cm will represent 500 cm. The drone mapping will not only help the SoI in getting unprecedented detail of country’s landscape but will also help in creating high resolution maps of land in villages facilitating digitisation of land titles there.
  • NCCCR&D:Water has been found by scientists in the atmosphere of an exoplanet called K2-18b. The exoplanet is twice the size and eight times the mass of Earth and hence, known as a super-Earth. Super-Earths are exoplanets that are larger than Earth but smaller than Neptune. The exoplanet orbits a red dwarf star, K2-18 and is 110 light-years away from Earth in the Leo constellation. It is the first planet outside the solar system in the habitable zone of its star.The K2-18b exoplanet completes one orbit around its star every 33 days.The super-Earth is much closer to its star than the Earth is to the sun. However, the red dwarf star is much cooler than the Sun. The discovery was published in a paper in a scientific journal, Nature Astronomy on September 11, 2019 by researchers from University College London (UCL). The paper revealed that scientists studied the atmosphere of K2-18b, a distant super-Earth and for the first time discovered water vapor in its atmosphere and temperature that could potentially support life. Though scientists have tagged exoplanet K2-18b as potentially habitable, it doesn’t mean that humans could live there. The research team used archived data collected by the Hubble Space Telescope between 2016 and 2017 that had captured starlight as it passed through the exoplanet’s atmosphere. When the researchers put the data through algorithms, they saw signs of water vapour in the atmosphere. The researchers also saw traces of hydrogen and helium in the atmosphere, two of the most abundant elements in the universe. The planet was first discovered by NASA's Kepler spacecraft in 2015.
  • Gaganyaan Mission :ISRO aims to launch its maiden Human Space Mission, Gaganyaan before the 75th anniversary of India’s independence in 2022. The Human Spaceflight Programme aims to carry three people to space to orbit the Earth for roughly about 7 days and bring them safely back to the ground. The crewed space mission is planned to be launched aboard ISRO’s GSLV Mk III in December 2021. So The Indian Space Research Organisation (ISRO) and Defence Research and Development Organisation (DRDO) signed a Memorandum of Agreement (MoU) for development of human-centric systems for the Human Space Mission to demonstrate its human space flight capabilities. The MoU was signed by a delegation of ISRO scientists, led by Human Space Flight Centre's Director, S Unnikrishnan Nair, with various DRDO labs in this regard, to provide technologies for human-centric systems and technologies specific to the Human Space Mission. Under the agreement, the technological capabilities existing in DRDO labs for defence applications will not only be customised to meet the requirements of ISRO’s human space mission but DRDO will also be providing critical technologies to ISRO such as space crew health monitoring and emergency survival kit, space food, parachutes for the crew module’s safe recovery and radiation measurement and protection.
  • CHC Farm Machinery:It is Multilingual Mobile App launched for farmers:The Union Minister of State for Agriculture and Farmers Welfare Purushottam Rupala recently launched a multilingual mobile app 'CHC Farm Machinery' during the National Conference on crop residue Management for farmers in Punjab, Haryana, Uttar Pradesh and Delhi. CHC Farm Machinery Mobile App will allow farmers to avail custom hiring services of CHCs located in a radius of 50 km. It will connect the farmers with Custom Hiring Service Centers in their area. Farmers can download this mobile app on any android phone from Google Play Store. Farmers can get affordable access to cutting-edge technology at their doorsteps with the help of this mobile app. The issue of crop residue burning has become a major environmental problem causing health issues as well as contributing to global warming. There are some sustainable techniques like Composting, biochar production and mechanization that can help to curtail the issue while retaining the nutrients present in the crop residue in the soil. However, some steps by the government of India have taken to curtail this problem. Several measures and campaigns designed to promote sustainable management methods such as converting crop residue into energy have also started. In recent years, the alarming rise of air pollution levels caused by crop residue burning in the city of Delhi and other northern areas in India observed.

Twenty-five vans are being added in September 2019, which is also part of 100-day achievement of this government.
  • Samudrayaan Project:India, after Chandrayaan project is planning to explore the deep sea region with the 'Samudrayaan' project to undertake deep ocean mining .The 'Samudrayaan' is a pilot project of the Ministry of Earth Sciences for deep ocean mining for rare minerals. The 'Samudrayaan' project proposes to send men into the deep sea in a submersible vehicle for ocean studies. The project is expected to become a reality by 2021-22. The project has been undertaken by the National Institute of Ocean Technology (NIOT). NIOT Director MA Atmanand said that NIOT has similarly undertaken Samudrayaan as ISRO has envisioned carrying an astronaut to space under its 2022 'Gaganyaan' mission. Under the proposed 'Samudrayaan' project, three men will be sent into deep sea in a submersible vehicle to a depth of about 6000 metres to carry out various deep underwater studies. The submersible vehicle, which will be indigenously developed, would be capable of crawling on the sea bed at a depth of six-kilometer for 72 hours.The project will go deeper in phases with more trials and the ocean mining is expected to commence in 2022.The submarines deployed currently go only about 200 metres deep into the sea. The expenditure of the ambitious project is expected to be around Rs 200 crore. The significance of Samudrayaan project that if it id successful then India will join the league of developed nations in the exploration of minerals from oceans Developed countries have already carried out such missions. India could be the first developing country to undertake such a project. The 'Samudrayaan' will be a part of the Rs 6000 crore 'Deep Ocean’ mission that though has received in-principle approval but it is still awaiting final approval from the Union Finance Ministry. The final approvals are expected to come through in October 2019.
  • Chandrayaan-2: Chandrayaan-2 is an Indian lunar mission to explore the unchartered south pole of the celestial body by landing a rover. It is developed by the Indian Space Research Organisation (ISRO),after Chandrayaan-1.It consists of a lunar orbiter, the Vikram lander, and the Pragyan lunar rover, all of which were developed in India.The main scientific objective is to map the location and abundance of lunar water via Pragyan, and ongoing analysis from the orbiter circling at a lunar polar orbit of 100 × 100 km. The mission was launched to the Moon from the second launch pad at Satish Dhawan Space Centre on 22 July 2019 at 2.43 PM IST (09:13 UTC) by a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III). The craft reached the Moon's orbit on 20 August 2019 and began orbital positioning manoeuvres for the landing of the Vikram lander. Vikram and the rover were scheduled to land on the near side of the Moon, in the south polar region at a latitude of about 70° south at approximately 1:50 am on 7 September 2019 and conduct scientific experiments for one lunar day, lasting two Earth weeks. However, at about 1:52 am IST, the lander deviated from its intended trajectory at around 2.1 kilometres (1.3 mi) from landing, and lost communication. Initial reports suggesting a crash have been confirmed by ISRO chairman K. Sivan, stating that the lander location had been found, and "it must had been a hard landing". The orbiter, part of the mission with eight scientific instruments, remains operational and will continue its seven-year mission to study the Moon. The Moon is the closest cosmic body at which space discovery can be attempted and documented. It is also a promising test bed to demonstrate technologies required for deep-space missions. Chandrayaan 2 attempts to foster a new age of discovery, increase our understanding of space, stimulate the advancement of technology, promote global alliances, and inspire a future generation of explorers and scientists. Moon provides the best linkage to Earth’s early history. It offers an undisturbed historical record of the inner Solar system environment. Though there are a few mature models, the origin of Moon still needs further explanations. Extensive mapping of lunar surface to study variations in lunar surface composition is essential to trace back the origin and evolution of the Moon. Evidence for water molecules discovered by Chandrayaan-1, requires further studies on the extent of water molecule distribution on the surface, below the surface and in the tenuous lunar exosphere to address the origin of water on Moon. The lunar South Pole is especially interesting because of the lunar surface area here that remains in shadow is much larger than that at the North Pole. There is a possibility of the presence of water in permanently shadowed areas around it. In addition, South Pole region has craters that are cold traps and contain a fossil record of the early Solar System.

The pilot study will be undertaken in 3 districts of Bhopal, Rajkot and Nanded in Madhya Pradesh, Gujarat and Maharashtra respectively.
  • Generic medicines:They are unbranded medicines which are equally safe and having the same efficacy as that of branded medicines in terms of their therapeutic value. The prices of generic medicines are much cheaper than their branded equivalent. Since the manufacture of these generic drugs do not involve a repeat of the extensive clinical trials to prove their safety and efficacy, it costs less to develop them. Generic drugs are, therefore, cheaper. However, because the compounds in the generic versions have the same molecular structure as the brand-name version, their quality is essentially the same. Since they are cheap, people who can afford branded drugs don’t buy them believing them to be of inferior quality. Chemists have to hand out exactly what’s written on the prescription and most doctors except in government hospitals don’t hand out generic drugs.
  • Sahiwal:This cattle is considered to be one of the best milch cattle breed of India. The breed derives its name from Sahiwal area in Montgomery district of Punjab in Pakistan. These animals are also known as “Lambi Bar”, “Lola”, “Montgomery”, “Multani” and “Teli”.

New dates will be announced in a few days. It was India’s second mission to the moon and aimed to explore the Moon’s south polar region. It was to be launched onboard India’s most powerful launcher – GSLV MK-III. The mission is an important step in India’s plans for planetary exploration, a program known as Planetary Science and Exploration (PLANEX).
  • SATAT: It which stands for Sustainable Alternative Towards Affordable Transportation is a developmental effort that would benefit both vehicle-users as well as farmers and entrepreneurs. Compressed Bio-Gas plants are proposed to be set up mainly through independent entrepreneurs. CBG produced at these plants will be transported through cascades of cylinders to the fuel station networks of OMCs for marketing as a green transport fuel alternative. The entrepreneurs would be able to separately market the other by-products from these plants, including bio-manure, carbon-dioxide, etc., to enhance returns on investment. This initiative is expected to generate direct employment for 75,000 people and produce 50 million tonnes of bio-manure for crops. There are multiple benefits from converting agricultural residue, cattle dung and municipal solid waste into CBG on a commercial scale.
  • Blockchains:They are a new data structure that is secure, cryptography-based, and distributed across a network. The technology supports cryptocurrencies such as Bitcoin, and the transfer of any data or digital asset. Spearheaded by Bitcoin, blockchains achieve consensus among distributed nodes, allowing the transfer of digital goods without the need for centralized authorisation of transactions.
  • AFRS:It stands Automated Facial Recognition System use by police officers across the country was recommended on June 28,2019 by the National Crime Records Bureau (NCRB). AFRS works by maintaining a large database with photos and videos of peoples’ faces. Then, a new image of an unidentified person — often taken from CCTV footage — is compared to the existing database to find a match and identify the person. The artificial intelligence technology used for pattern-finding and matching is called “neural networks”. NCRB has proposed integrating this facial recognition system with multiple existing databases. The most prominent is the NCRB-managed Crime and Criminal Tracking Network & Systems (CCTNS). Facial recognition has been proposed in the CCTNS program since its origin.
  • Bhabha Kavach: It is the name of India’s first Lightest and indigenous Bullet Proof Jacket ‘from Ordnance Factory Board which recently received the nod of MHA. Developed by OFB and MIDHANI this state-of-the-art jacket can withstand 7.62mm hard steel core or bullets fired from an AK-47 rifle, 5.56mm INSAS bullet and even the recently decommissioned 7.65mm bullet of self-loading rifle (SLR). It is half KG lesser than the prescribed weight of MHA along with the 360 Degree Protection and has achieved the protection level of NIJ III+. Bhabha Kavach only weighs 9.2kg and is a major breakthrough for the Indian armed forces.
  • ETPBS: It stands for Electronically transmitted Postal Ballot System is developed by Election Commission of India with the help of Centre for Development of Advanced Computing (C-DAC), for the use of the Service Voters. It is a fully secured system, having two layers of security. Secrecy is maintained through the use of OTP and PIN and no duplication of casted Electronically Transmitted Postal Ballot (ETPB) is possible due to the unique QR Code. Persons working in paramilitary forces and the military and government officials deployed in diplomatic missions outside India are classified as Service Voters. In the seven phases Lok Sabha polls, a record 18,02,646 eligible personnel were enrolled and 10,84,266 voted through the Electronically Transmitted Postal Ballot System (ETPBS) or e-postal ballots.
  • NavIC: It stands for Navigation with Indian Constellation is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland. IRNSS would provide two types of services, namely Standard Positioning Services available to all users and Restricted Services provided to authorised users. ISRO is in talks with processing chip manufacturers such as Qualcomm to substitute the existing Global Positioning System (GPS) with the Indian version of satellite navigation. It is a regional system and so its constellation will consist of seven satellites. Three of these will be geostationary over the Indian Ocean, i.e., they will appear to be stationary in the sky over the region, and four will be geosynchronous – appearing at the same point in the sky at the same time every day. This configuration ensures each satellite is being tracked by at least one of fourteen ground stations at any given point of time, with a high chance of most of them being visible from any point in India.
  • JATAN:It is software for Digitization of Archaeological Museum. Human Centres Design and Computing Group has developed JATAN which is a virtual Museum software which is used for creating the digital collections in various museums and digital archival tools that are used in background for managing the National Portal and Digital Repository for Indian Museums.
  • Microdot technology:It involves spraying the body and parts of the vehicle or any other machine with microscopic dots, which give a unique identification. These microdot can be read physically with a microscope and identified with ultra violet light source. The microdots and adhesive will become permanent fixtures/affixation which cannot be removed without damaging the asset, which is the vehicle itself. The Ministry of Road Transport & Highways has issued a draft notification amending Central Motor Vehicle Rules, allowing motor vehicles and their parts, components, assemblies, sub-assemblies to be affixed with permanent and nearly invisible microdots.
  • Colistin: It is a a valuable, last-resort antibiotic whose manufacture, sale and distribution for food-producing animals, poultry, aqua farming and animal feed supplements have been prohibited in an order issued by Ministry of Health and Family Welfare. Colistin is a valuable, last-resort antibiotic that saves human lives in critical care units.Indiscriminate use of colistin has led to rise of anti-microbial resistance in the country.If the use of colistin as a growth factor in animals is cut down and it is limited to therapeutic usage only, the chances of developing resistance to it goes down.
  • Regulatory Sandbox:It is a safe harbour, where businesses can test innovative products under relaxed regulatory conditions. It was in the news as the Insurance Regulatory and Development Authority of India (IRDAI) will soon allow the use of regulatory sandbox (RS) to promote new, innovative products and processes in the industry. Typically, participating companies release new products in a controlled environment to a limited number of customers for a limited period of time.For the IRDAI sandbox, an applicant should have a net worth of Rs 10 lakh and a proven financial record of at least one year. Companies will be allowed to test products for up to 12 months in five categories. The “regulatory sandbox” will help fintech companies launch innovative products at a lower cost and in less time.

  • SKA:Which stands for Square Kilometre Array is the name of the world’s largest radio telescope which the scientists at Cambridge recently finished brain designing. It consists of a supercomputer that will process the enormous amounts of data produced by the SKA’s telescopes. The total compute power will be around 250 PFlops — that’s 25 per cent faster than IBM’s Summit, the current fastest supercomputer in the world. When complete, the SKA will enable astronomers to monitor the sky in unprecedented detail and survey the entire sky much faster than any system currently in existence. The Square Kilometre Array (SKA) project is an international effort to build the world’s largest radio telescope, with eventually over a square kilometre (one million square metres) of collecting area. Whilst 10 member countries are the cornerstone of the SKA, around 100 organisations across about 20 countries are participating in the design and development of the SKA. Location of SKA antenna dishes will be built in South Africa (in the Karoo), with outstations in other parts of South Africa, as well as in eight African partner countries, namely Botswana, Ghana, Kenya, Madagascar, Mauritius, Mozambique, Namibia and Zambia. Another part of the telescope, the low-frequency array, will be built in Western Australia.
  • Athena and LISA: These are the two future missions of ESA which the researchers have proposed to combine the observing power to study the effects when two supermassive black holes collide. Currently in the study phase, both missions are scheduled for launch in the early 2030s. Athena will be the largest X-ray observatory ever built, investigating some of the hottest and most energetic phenomena in the cosmos with unprecedented accuracy and depth. LISA will be the first space-borne observatory of gravitational waves—fluctuations in the fabric of spacetime produced by the acceleration of cosmic objects with very strong gravity fields, like pairs of merging black holes.
  • Akash-MK-1S: It is the name of missile which was successfully test fired by India from the integrated test range at Chandipur in Odisha. The surface-to-air anti-aircraft missile with a strike range of 25 km and capability to carry warhead of 60 kg. Akash weapon system has combination of both command guidance and active terminal seeker guidance.
  • RISAT-2B :It is the name of country’s newest microwave Earth observation satellite which rode to its orbit 557 km above the ground recently. With the successful pre-dawn launch of RISAT-2B satellite, the Indian Space Research Organisation (ISRO) has added another feather to its cap. Data that will come from the all-weather day-and-night satellite are considered to be vital for the Armed Forces as also agriculture forecasters and disaster relief agencies. Dubbed as a ‘spy’ satellite, RISAT-2B (Radar Imaging Satellite-2B) will replace its predecessor RISAT-2 which has been actively used by India to monitor activities in terror camps across the border in Pakistan to thwart infiltration bids by terrorists.
  • DRDO :It recently conducted maiden test of an indigenously developed Hypersonic Technology Demonstrator Vehicle (HSTDV). HSTDV is an unmanned scramjet demonstration aircraft. HSTDV is dual-use technology and can have multiple civilian applications. It can be used for launching satellites at low cost and can also be available for long-range cruise missiles of future.
  • Data localization :It is the act of storing data on any device that is physically present within the borders of a specific country where the data was generated. Data localization is necessary for India for securing citizen’s data, data privacy, data sovereignty, national security, and economic development of the country. Recommendations by the RBI, the committee of experts led by Justice BN Srikrishna, the draft ecommerce policy and the draft report of the cloud policy panel show signs of data localisation. The extensive data collection by technology companies, has allowed them to process and monetize Indian users’ data outside the country. Therefore, to curtail the perils of unregulated and arbitrary use of personal data, data localization is necessary. Digital technologies like machine learning (ML), artificial intelligence (AI) and Internet of Things (IoT) can generate tremendous value out of various data. It can turn disastrous if not contained within certain boundaries. The Srikrishna Committee wants to localise data for law enforcement to have easy access to data, to prevent foreign surveillance, to build an artificial intelligence ecosystem in India, and because undersea cables through which data transfers take place are vulnerable to attacks.
  • Anthrax :It is a disease caused by Bacillus anthracis, a germ that lives in soil. It affects animals such as cattle, sheep, and goats more often than people. People can get anthrax from contact with infected animals, wool, meat, or hides. It can cause three forms of disease in people. Anthrax does not spread directly from one infected animal or person to another; it is spread by spores. These spores can be transported by clothing or shoes. Anthrax can be contracted in laboratory accidents or by handling infected animals or their wool or hides.
  • AWaRe :It is an online tool aimed at guiding policy-makers and health workers to use antibiotics safely and more effectively. The tool, known as ‘AWaRe’, classifies antibiotics into three groups: Access — antibiotics used to treat the most common and serious infections. Watch — antibiotics available at all times in the healthcare system. Reserve — antibiotics to be used sparingly or preserved and used only as a last resort. Antibiotic resistance is already one of the biggest health risks and is estimated to kill 50 million by 2050 worldwide. The threat continues to escalate globally because more than 50 per cent of antibiotics in many countries are used inappropriately such as for treatment of viruses when they only treat bacterial infections or use of the wrong (broader spectrum) antibiotic.
  • ICANN & NASSCOM :Internet Corporation for Assigned Names and Numbers (ICANN) and NASSCOM (National Association of Software and Services Companies) have announced collaboration for working in developing standards and identifier technology that will feed into the global consultation for managing Internet-of-Things (IoT) devices and infrastructure using internet. The Internet Corporation of Assigned Names and Numbers (ICANN) is a non-profit organization that was set up in 1998 to oversee the administration of domain names. ICANN coordinates and ensures the smooth and secure functioning of the cybernetic framework. The global nature of the Web today means that there are constantly increasing numbers of Domain Names, Host Names, IP addresses and web sites that are emerging on a daily basis. ICANN oversees this interconnected network and ensures that computers across the internet can find one another through defined unique pathways and identifiers.

Developed by the Indian Space Research Organisation, the mission is planned to be launched to the Moon by a Geosynchronous Satellite Launch Vehicle Mark III. The Indian Space Research Organisation (ISRO) announced the launching of Chandrayaan-2,’ India’s second lunar mission’ which is scheduled to be launched between July 9th and 16th 2019. Chandrayaan-2 is India’s second lunar mission. It will be launched using India’s most powerful rocket GSLVMK-III RIN Satish Dhawan Space Centre in Sriharikota in Andhra Pradesh. It’s objective is to collect scientific information on lunar (moon) topography, mineralogy, elemental abundance, lunar exosphere and and signatures of hydroxyl and water-ice. It has three modules (a detachable self-contained unit of a spacecraft) namely Orbiter, Lander named Vikram and Rover named Pragyan.All these three modules have been made in India. The Chandrayaan-2’s lander will touch down near Moon’s south pole on 6th September 2019. Chandrayan-2 mission would make a soft landing on southern pole of the moon, which is still unexplored by any of the countries. This will not only be important but also historically significant as it would give ISRO the opportunity to name the site on the moon.
  • Yeti:
    It is a folkloric ape-like creature taller than an average human, that is said to inhabit the Himalayan mountains. Indian Army Mountaineering Expedition to Mt Makalu claims to have discovered the footprints of snowman ‘Yeti’ the abominable snowman as it is known in legends, near the Makalu Base Camp by posting photographs of ‘ mysterious footprints’ that measure about 32×15 inches, on Twitter. But several scientists that are based at Dehradun-based Wildlife Institute of India (WII), who have worked in Nepal , also said the footprints could be those of a bear. Besides the Joint secretary of Nepal’s forest department Maheshwar Dakal said the Makalu-Barun National Park has a healthy population of the brown bear but they have no evidence that the Yeti exists in the area. ‘We cannot ascertain the presence of the Yeti unless we have the picture of yeti as a proof. The footprint does not explain all and could be of bear or snow leopard,’ Dakal said.
  • IIT Madras: It is a public engineering institute that was set up in the year 1959 in Madras through an Act of Parliament. In a significant development, a research team from IIT Madras has developed a common unified script for nine Indian Languages. According to different sources, the script was developed taking cue from European languages, were several of them had the same (Roman letter–based) script. The team led by Srinivasa Chakravathy’s team at IIT Madras developed developed a unified script for nine Indian languages, named the Bharati script. The team has now gone a step further since developing the script: it has developed a method for reading documents in Bharati script using a multi-lingual optical character recognition (OCR) scheme. The team has also created a finger-spelling method that can be used to generate a sign language for hearing-impaired persons. In collaboration with TCS Mumbai, the researchers have found a way for persons with hearing disability to generate signatures using this finger-spelling technique.

  • Mars: It is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. NASA spacecraft has detected what's believed to be a ‘marsquake' on planet Mars. According to report from NASA, the space agency's InSight lander, which touched down on Mars in November after a seven-month journey, sensed the seismic signal on April 6. Mission scientists are still working to confirm the source of the faint trembling, though it appears to have come not from the wind or movement of the lander's robotic arm but from below the Martian surface. If confirmed, it would be the first seismic activity ever detected on Mars. 'We've been collecting background noise up until now, but this first event officially kicks off a new field: Martian seismology!' Bruce Banerdt, a geologist at NASA's Jet Propulsion Laboratory in Pasadena, California, and the principal investigator of the InSight mission, said in a statement. The 800-pound lander is parked on the Elysium Planitia, a broad, mostly rock-free plain just north of the Martian equator. The lander is designed to operate on the surface of Mars for two years, learning about the Martian interior as a way to boost our understanding of the formation of Mars and other rocky worlds, including Mercury, Venus, Earth and the moon.
  • Genome Sequencing : It is the process of determining the complete DNA sequence of an organism's genome at a single time. In a bid to educate students about the usefulness of genomics, Council of Scientific and Industrial Research (CSIR) has decided to map the population diversity. According to a report, nearly 1,000 rural youth from the length and breadth of India will have their genomes sequenced by the Council of Scientific and Industrial Research (CSIR). Globally, many countries have undertaken genome sequencing of a sample of their citizens to determine unique genetic traits, susceptibility (and resilience) to disease. This is the first time that such a large sample of Indians will be recruited for a detailed study. The project is an adjunct to a much larger government-led programme, still in the works, to sequence at least 10,000 Indian genomes.
  • Antibotics: They also known as antibacterials, are medications that destroy or slow down the growth of bacteria. With reports of adverse reactions after the usage of commonly-used antibiotics, the Central Drugs Standard Control Organisation (CDSCO) has now asked manufacturers to ensure that this information be made available to the general public. In a letter to drug manufacturers, CDSCO asked them to mention in leaflets inserted into drug packets or on promotional literature, information about the adverse reactions of these medicines. All of the seven formulations — antibiotics Cefotaxime, Ofloxacin and Cefixime; Tranexamic Acid, used to control bleeding; antipsychotic drug Quetiapine; anti-rheumatoid drug Sulfasalazine and the anti-epileptic medicine Sodium Valproate — have been instructed to warn patients of the new side effects. The letter was sent out by CDSCO on April 9.
  • Homo luzonensis : It is an extinct species of the genus Homo. Researchers in the Philippines have discovered a species of ancient human Homo Luzonensis which was previously unknown to science. The small-bodied hominin, named Homo luzonensis, lived on the island of Luzon at least 50,000 to 67,000 years ago. The hominin—identified from a total of seven teeth and six small bones—hosts a patchwork of ancient and more advanced features. The landmark discovery, announced in Nature on Wednesday, makes Luzon the third Southeast Asian island in the last 15 years to bear signs of unexpectedly ancient human activity. Scientists have for a long, long time, felt that there is nothing Philippine islands. Homo luzonensis flips the script, and it continues to challenge the outdated idea that the human line neatly progressed from less advanced to more advanced species.
  • Mitochondrial donation: It is an experimental IVF treatment involving an egg from the mother, sperm from the father and another egg from a female donor. A baby with DNA from three people has been born in Greece following this fertility treatment. The baby boy, weighing 2.9kg (6lb) was born. Both he and his mother, who is 32, are said to be in good health. The doctors behind the treatment, from Greece and Spain, said that the birth marks a historic advance – it is the first time an IVF technique involving DNA from three people has been used with the aim of addressing fertility problems. But UK experts criticised the decision to proceed with the treatment, which they said was not backed by evidence and involved unjustifiable risks.
  • Stratolaunch aircraft: It is a world’s largest airplane which completed its first test flight. According to officials, the aircraft achieved its maximum speed of 189 miles per hour (302.4 km per hour).

The plane has a dual fuselage design and its wingspan is greater than the length of an American football field. As per the information provided on the Stratolaunch website, the test flight took off from Mojave Air and Space Port in California at 6:58 am Pacific Time (7:28 pm India time). As part of the initial flight, the pilots evaluated aircraft performance and handling qualities before landing successfully back at the Mojave Air and Space Port, Stratolaunch said in a statement. The test team conducted standard aircraft testing exercise including a variety of flight control manoeuvres to calibrate speed and test flight control systems. The Stratolaunch aircraft is designed to act as a flying launch pad for satellites and put payloads in orbit. With 117 meters wingspan and 73 meters nose-to-tail length, the company describes its aircraft as the world’s largest plane. While it does have the largest wingspan, it does not have the longest nose-to-tail length.
  • Self destructive mechanism : It is new mechanism discovered by Chinese scientist. It is also known as death switch mechanism. According to officials, this mechanism will triggers infected cells to self-destruct, thus limiting the spread of the disease and keeping other parts of the plant healthy. This research can lead to a new generation of disease-resistant crops that use significantly less pesticide and are more environmentally friendly. The research was done by scientists from Tsinghua University and the Chinese Academy of Sciences' Institute of Genetics and Development Biology. Their findings were published in the journal Science. About 20 years ago, scientists discovered that plants, like animals, have robust immune systems that can protect them from pathogens including viruses, fungi, bacteria and parasites.

  • Spacex Falcon : It is the most powerful and reusable heavy-lift launch vehicle designed and manufactured by SpaceX launches the world first commercial mission. The launch is considered as a key demonstration for billionaire entrepreneur Elon Musk's space company in the race to grasp lucrative military launch contracts. Roughly three minutes after clearing the launch pad, Falcon Heavy's two side boosters separated from the core rocket for a synchronised landing at the Cape Canaveral Air Force Station, just like it did for the rocket's debut last year. The middle booster, after pushing the payload into space, returned nearly 10 minutes later for a successful landing on SpaceX's seafaring drone ship waiting 645 kilometres off the Florida coast. A successful lift-off with Falcon Heavy's new military-certified Falcon 9 boosters was a crucial element in the race against Boeing-Lockheed venture United Launch Alliance and Jeff Bezos' Blue Origin to secure lucrative military contracts. Musk's SpaceX, working to prove the flight-worthiness of its rocket fleet one mission at a time, aims to clinch one-third of all US National Security Space missions — coveted contracts that are worth billions of llars. The US Air Force tapped SpaceX in 2018 to launch a classified military satellite, which cost it USD 130 million and in February added three more missions in a USD 297 million contract.

  • Global Positioning System (GPS): It is a satellite navigation system used to determine the ground position of an object. Researchers from the Massachusetts Institute of Technology (MIT) have developed an in-body GPS system, called ReMix, which can identify the location of ingestible implants inside the body via low-power wireless signals. Scientists team expects that such implants can be used to track tumours by monitoring even slight movements. In the future, the implants may also help in dispensing drugs to a specific area in the body. ReMix is being developed by MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) in alliance with Massachusetts General Hospital (MGH). The in-body GPS system is based on a wireless technology that MIT previously developed to detect heart rate, breathing and movement. To validate the system, the researchers implanted a small marker in animal tissues. They used a wireless device that reflects radio signals off the patient to track the marker's movement. This marker does not transmit any signals of its own. It merely reflects those transmitted by the wireless device. As a result, the marker does not need a battery or any external source of energy.

The other two species, Gymnothorax visakhaensis (uniformly brown) and Enchelycore propinqua (reddish brown body mottled with irregular creamy white spots), were discovered from the Visakhapatnam coast of the Bay of Bengal. While Gymnothorax pseudotile is about 1 feet to 1.5 feet long, Gymnothorax visakhaensis is about a foot long. Enchelycore propinqua is the smallest of them measuring less than a foot. A description of all the three new species was published in the journal Zootaxa.

  • World's smallest satellite - Japan successfully launched on the world's smallest satellite-carrying rocket following a failed attempt in January last year. According to a release from the Japan Aerospace Exploration Agency, 'The rocket about the size of a utility pole, measuring 10 meters in length and 50 centimeters in diameter, lifted off from the Uchinoura Space Center in Kagoshima Prefecture and delivered its payload to its intended orbit'. The No. 5 vehicle of the SS-520 series carried a microsatellite weighing about 3 kilograms developed by the University of Tokyo to collect imagery of the Earth's surface. The launch was aimed at verifying JAXA's technology used to launch small rockets made with commercially available components at lower cost amid growing global demand for microsatellites. The agency used components found in home electronics and smartphones for the rocket. JAXA launched the No. 4 vehicle on Jan. 15 last year, but terminated its flight shortly after liftoff due to a communications problem. The agency found that vibrations during liftoff caused a short circuit, leading to a loss of power in the data transmitter. For Saturday's launch, the agency made more than 40 improvements to prevent a recurrence.
