1 - NASA announced a new mission to explore Saturn's largest moon
NASA announced a new mission to explore this fascinating world with a helicopter drone. The mission, called Dragonfly is the latest in NASA’s New frontier program. NASA has earlier launched explorations of Pluto, Jupiter, the asteroid Bennu, and now, Titan.
Titan, the largest moon of Saturn, has a lot in common with Earth. It has a thick, nitrogen-dense atmosphere and features like rivers, lakes, mountains, and, potentially volcanoes. The atmosphere of Titan is four times as dense as the Earth’s and there’s less gravity which makes it a prime location in the solar system to deploy a drone.
Dragonfly is planned to launch in 2026 and arrive at Titan in 2034. With its eight rotors, Dragonfly will be able to fly tens of miles in a given day. It is powered by a plutonium battery.
Two-year mission, Dragonfly will travel hundreds of miles across the surface. sampling the chemistry of the moon and studying its geology and atmosphere. It will also look out for signs of life.
The study on Titan’s methane cycle is interesting as Methane (the primary ingredient in natural gas) actually forms clouds and rains down on the surface of Titan, a lot like how water rains on Earth.
By studying the weather pattern on Titan, a better picture about the greater reaches of the cosmos, and help scientists understand what makes a planet or moon habitable or not.Giant asteroid ‘99942 Apophis’ will fly past Earth in a decade
The 340m wide asteroid named 99942 Apophis will fly past Earth like a ‘moving star- like point of light’ on April 13, 2029. It will fly above the earth’s surface at 30,500 km and first become visible with a naked eye in the night sky over the Southern Hemisphere from the east coast to the west coast of Australia.
2 - NASA's Curiosity rover confirmed the presence of Methane in Mars
NASA has confirmed that the Curiosity rover, the NASA's Mars Science Laboratory mission, recently detected the largest amount of methane ever measured during the mission. Curiosity's methane reading came to 21 parts per billion units by volume. It is thrice the amount it sniffed out during a surge in 2013.
During a follow-up test later, though, scientists found that the methane levels around the rover already dropped sharply. Curiosity detected normal methane levels, that is 1 part per billion by volume, following the sudden elevation. It suggested that the abnormally high values came from transient methane plumes.
As Curiosity is not equipped with instruments to determine whether the source of methane is biological or geological, the scientists are yet to figure out a pattern for Martian's transient plumes.
The scientists plan to gather more information through Curiosity and from other missions to gain a deeper understanding of the plumes. The scientist will be able to understand whether the presence of methane on the red planet truly is a sign of life only if they finds where the plumes are coming from.
Methane is a gas formed by both geological and biological processes.
It is the main constituent of natural gas. It is a group-14 hydride and the simplest alkane with the chemical formula CH4.
The methane concentration in earth's atmospheric has increased by about 150% since 1750.
Methane accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases.

10 - MoSPI has proposed to set up a National Data Warehouse to leverage big data analytical tools
Ministry of Statistics and Programme Implementation (MoSPI) has proposed to set up a National Data Warehouse with an aim to leveraging big data analytical tools. This move is to further improve the quality of macro-economic aggregates. MoSPI also plans to introduce a legislative framework so that the National Statistical Commission (NSC) can function with independence and give holistic guidance for improving the national statistical system.
The move also lends its support to the system reforms that are currently ongoing. It will also ensure theresponsiveness to the changing needs of society that are necessary. This proposed set up is necessary as there are increasing demands on the statistical system for the production of relevant and quality statistics.
National Data Warehouse for macro-economic aggregate
The Ministry also proposed to establish a National Data Warehouse on Official Statistics. Here, the technology will be leveraged for using big data analytical tools for further improving the quality of macro-economic aggregates.
MoSPI has been criticized in some sections for the quality of macro-economic data.
Merger of merger of CSO and NSSO
Regarding this the government has recently merged the Central Statistical Organisation (CSO) and the National Sample Survey Office (NSSO) to streamline and strengthen the statistical system. The merger leveraged the strengths of the two organisations so that it can meet the increasing demands.
The government use the statistical data to revise the GDP estimate would require concomitant changes in the sectoral data flows and associated regulatory framework in the data source agencies to facilitate the use of more macro modelling techniques.

17 - Facebook plans to launch its cryptocurrency, GlobalCoin, by the first quarter of 2020
Facebook plans to launch its cryptocurrency by the first quarter of 2020. The company is expected to reveal more details about the currency before testing begins later in 2019. The currency, which is being referred to internally as “GlobalCoin,” will reportedly be available in around a dozen countries at launch, where it’s expected to offer people affordable and secure payments without the need for a bank account.
The currency will need to overcome numerous technical and regulatory hurdles before it can be launched. Facebook CEO Mark Zuckerberg met with the Bank of England’s governor Mark Carney to discuss the opportunities and risks of the planned digital currency.
However, Facebook might have a harder job on its hands in India, which has taken a hostile attitude towards virtual currencies. India is reported to be a key focus for the new currency, where Facebook hopes it will allow Indian workers abroad to send money back home to their families using WhatsApp.
What is a Cryptocurrency?
A cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. It is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
The first blockchain-based cryptocurrency was Bitcoin, which still remains the most popular and most valuable. Today, there are thousands of alternate cryptocurrencies with various functions or specifications.
