Google Cloud and Flipkart Enter a Strategic Partnership

Google Cloud and e-commerce firm Flipkart, entered into a multi-year strategic partnership to help fast-track Flipkart's innovation and cloud strategy. The partnership would propel Flipkart into its next phase of growth and advance its vision of onboarding India's next 200 million shoppers and lakhs of sellers.
The strategic alliance with Google Cloud would enable Flipkart to accelerate our digital transformation, power productivity and advance our innovation agenda.
By leveraging Google Cloud's secure and scalable global infrastructure and advanced networking technologies, Flipkart would be able to deliver robust app access and performance even during peak purchase seasons with heightened traffic. Flipkart will also continue to advance the pace of new product development by building on Google Cloud, furthering its expansion into Tier 2 and Tier 3 markets in India.

Chandrayaan-2 Orbiter Makes New Discovery about Distribution of Gas in Moon's Atmosphere

India's Chandrayaan-2 orbiter made new observations about the distribution of an important gas in the moon's upper atmosphere, which can offer new insights into the lunar surroundings.
New data from Chandra's Atmospheric Composition Explorer-2 (CHACE-2) mass spectrometer on Chandrayaan-2 show the distribution of Argon-40 gas in the lunar 'exosphere', beyond the areas this was known to exist.
Though, Argon-40 (Ar-40) is known to exist in the lunar exosphere, the knowledge on its distribution at higher latitudes is lacking. For the first time, Chandra's Atmospheric Composition Explorer-2 experiment aboard Chandrayaan-2 orbiter has continuously observed Ar-40 in latitude range of -60 to +60 degrees.

Astronomers Detect Largest Organic Molecule ever Found in a Stellar 'Dust Trap'

Astronomers detected the largest organic molecule ever seen in a cloud of planet-forming dust, potentially offering new insights into the way that the building blocks of life end up on planets.
Using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile, researchers studied the light emitted by different molecules in the lopsided ring of dust and ice surrounding the young star IRS 48, located about 444 light-years from Earth in the constellation Ophiuchus.
Within the dusty ring, the researchers saw clear traces of an organic compound called dimethyl ether — a large molecule that's commonly detected in stellar nurseries (cold, dusty regions of space where new stars form) and is a precursor to crucial building blocks of life, such as amino acids and sugars.

Engineers Begin Assembly of NASA's Europa Clipper

NASA's Europa Clipper spacecraft will conduct detailed reconnaissance of Jupiter's moon Europa to see whether the icy moon could harbor conditions suitable for life, honing our insights into astrobiology.
Europa Clipper would orbit Jupiter about every two weeks, providing many opportunities for close flybys of Europa.
In total, the solar-powered orbiter would perform 45 flybys at altitudes ranging from 25 to 2,700 km (16 to 1,700 miles), imaging the moon's icy surface at high resolution and investigating its composition and the structure of its interior and icy shell.
When it's fully assembled, Europa Clipper will be as large as an SUV with solar arrays long enough to span a basketball court.

North Korea Confirms New Tests on Spy Satellite

North Korea performed data transmission and other key tests needed to develop a spy satellite, in the second such tests in about a week, indicating the country intends to conduct a prohibited long-range rocket launch soon.
The moves come as North Korea has been carrying out a spate of ballistic missile launches -- including one detected by its neighbors -- in what experts call an attempt to add new weapons systems to its arsenal and pressure the United States into making concessions amid stalled diplomacy.
As per reports, N. Korea had conducted another important test the previous day under its plan to develop a reconnaissance satellite. Authorities confirmed the reliability of the satellite's data transmission and reception system, in addition to its control and command system and various ground-based control systems.

India's Largest EV Charging Station for 4 Wheelers Opens in Gurugram

India's largest electric vehicle (EV) charging station with a capacity of 121 charging points for 4 wheelers, was opened in Sector 86 of Gurugram.
With this EV station, the city has now two of the largest electric vehicle charging stations in the country.
The first EV station was opened earlier in January with a capacity of 100 charging points for 4 wheelers in Sector 52 of Gurugram.
Alektrify Private Limited has developed the new EV charging station under the Ease of Doing Business program.

Indian Railway Turns Self-reliant: Tests Collision Preventing System 'Kavach'

The Indian railway, after years of systematic planning and rounds of track-based trials, has turned self-reliant in preventing head-on collision even when two trains, either out of a possible human error or an abrupt technical failure, come running on the same track.
The railway has set off the successful trial and testing of indigenously developed Train Collision Avoidance System (TCAS), called 'Kavach'.
Union Railway Minister Ashwini Vaishnaw, along with Chairman of Railway Board and ministry officials, attended a live successful demonstration of an error-free functioning of indigenously developed Train Collision Avoidance System (TCAS), 'Kavach'.
The "Kavach" technology applies the brakes automatically soon after spotting another train coming from the opposite direction on the same track and stops the train at a safe distance.
As a SIL-4 certified technology, "It also halts the train soon after it jumps the red signal or controls the speed after the train goes beyond the prescribed speed limit.

NASA, ULA Launch GOES-T

NASA successfully launched the third in a series of next-generation weather satellites for the National Oceanic and Atmospheric Administration (NOAA). The newest Geostationary Operational Environmental Satellite, GOES-T was launched on a United Launch Alliance Atlas V rocket from Cape Canaveral Space Force Station.
The satellite would provide continuous coverage of weather and hazardous environmental conditions in the Western Hemisphere. The GOES program also predicts space weather near Earth that can interfere with satellite electronics, GPS, and radio communications.
Once GOES-T is positioned in a geostationary orbit 22,300 miles above Earth, it will be renamed GOES-18. Following a successful orbital checkout of its instruments and systems, GOES-18 will go into service over the U.S. West Coast and Pacific Ocean.

Moon's World Rocked as Tons of Space Junk Likely to Punch 20-metre Hole

The peace and tranquility on the Moon was disturbed as a three-ton rocket plummeted into the surface, carving out a crater that could fit several semitractor-trailers. A rocket hit the lunar surface however telescopes and prying eyes will not be able to track the mega-collision.
Telescopes could not pick up the collision since the strike happened on the far side of the Moon that remains away from the sunlight permanently. This made it difficult to locate the newly formed crater.
