Did Vikram lose control and<br />

crash land on the moon?<br />

Chennai, Did India s first<br />

moon lander Vikram crash on<br />

to the lunar surface resulting in<br />

the sudden snapping of the<br />

communication link with the<br />

Chandrayaan-2 Orbiter? All<br />

was going well with the 1,471<br />

kg Vikram that began its<br />

descent at about 1.38 a.m. on<br />

Saturday from an altitude of 30<br />

km at a velocity of 1,680<br />

metres per second.<br />

Announcing the snapping of<br />

communication links, Indian<br />

Space Research Organisation<br />

(ISRO) Chairman K. Sivan said<br />

that the performance of the lander<br />

was as per the plan till it<br />

was 2.1 km from the moon surface.<br />

The communication link got<br />

snapped after that, he added.<br />

In an official statement, the<br />

ISRO said: This is Mission<br />

Control Centre. Vikram lander<br />

descent was as planned and<br />

normal performance was<br />

observed up to an altitude of<br />

2.1 km. Subsequently communication<br />

from lander to the<br />

ground stations was lost. Data<br />

is being analysed.<br />

On the screen at ISRO s<br />

telemetry, tracking and command<br />

network (Istrac) centre, it<br />

was seen that Vikram slightly<br />

How embryo develops at<br />

molecular level decoded<br />

Washington : Researchers in the US<br />

have created the first detailed map of the<br />

changes at the molecular level in cells that<br />

lead to embryonic development.<br />

The research, published in the journal<br />

Science, used the latest technology from<br />

the emerging field of single cell biology<br />

the study of all chemical processes happening<br />

at the cellular level to profile<br />

more than 80,000 cells in the embryo of<br />

the worm Caenorhabditis elegans.<br />

"Over the past few years, new single<br />

cell genomics methods have revolutionised<br />

the study of animal development,"<br />

said John I Murray from the<br />

University of Pennsylvania in the US.<br />

"Our study takes advantage of the fact<br />

that the C. elegans embryo has a very<br />

small number of cells produced by a<br />

known and completely reproducible pattern<br />

of cell divisions. Using single cell<br />

genomics methods, we were able to identify<br />

over 87 per cent of embryonic cells<br />

from gastrulation (when there are about 50<br />

cells present) through the end of embryogenesis,"<br />

he added.<br />

The worm hatches with only 558 cells<br />

in its body, and like every multicellular<br />

organism, each of its cells is derived from<br />

division from a single fertilized egg.<br />

changed from its planned path<br />

and then the communication<br />

link got snapped.<br />

The lander was smoothly<br />

coming down with the ISRO<br />

officials applauding at regular<br />

intervals and their faces beaming<br />

with pride.<br />

The lander successfully<br />

completed its rough braking<br />

phase with its descent speed<br />

going down well.<br />

So what went wrong at the<br />

last moment?<br />

According to an ISRO official,<br />

the lander could have lost<br />

its control when its thrusters<br />

were switched off during its<br />

descent and crash-landed snapping<br />

Meanwhile all is not lost as<br />

far as the Rs 978 crore<br />

Berlin : Chinese smartphone manufacturer<br />

Huawei on Friday launched its latest<br />

Kirin 990 (5G) flagship chipset with an<br />

integrated 5G modem at the IFA <strong>2019</strong><br />

here. Kirin 990 (5G) is the world s first<br />

5G SoC, and it will enable end-users to<br />

access superb 5G connectivity experience<br />

one step ahead in the first year of 5G commercialization.<br />

To meet users requirements for<br />

enhanced 5G experiences in the 5G era,<br />

Kirin 990 (5G) has been fully upgraded in<br />

terms of performance and power efficiency,<br />

AI computing, and ISP, extending<br />

mobile phone experiences to a new level,<br />

Richard Yu, Huawei s consumer business<br />

CEO said in a statement.<br />

Kirin 990 (5G) is the first full-frequency<br />

5G SoC to support both non-standalone<br />

(NSA) and standalone (SA) architectures<br />

as well as TDD/FDD full frequency bands,<br />

enabling it to accommodate<br />

hardware<br />

requirements under<br />

diverse networks and<br />

networking modes.<br />

It is the first flagship<br />

SoC that packs<br />

a dual-core NPU<br />

built on the Da Vinci<br />

architecture, which<br />

comprise large and<br />

tiny NPU cores. The<br />

large cores achieve<br />

Chandrayaan-2 mission is concerned.<br />

Only 5 per cent of the<br />

mission has been lost Vikram<br />

the lander and Pragyan the<br />

rover while the remaining 95<br />

per cent that is the<br />

Chandrayaan-2 orbiter is<br />

orbiting the moon successfully,<br />

an ISRO official told IANS<br />

who did not want to be identified.<br />

With a mission life of one<br />

year, the Orbiter can take several<br />

pictures of the moon and<br />

send it to the ISRO.<br />

The Orbiter can also take<br />

pictures of the lander to know<br />

its status, he added.<br />

The Chandrayaan-2 spacecraft<br />

comprised three segments<br />

the Orbiter (weighing 2,379<br />

kg, eight payloads), Vikram<br />

(1,471 kg, four payloads) and<br />

Pragyan (27 kg, two payloads).<br />

On July 22, the Rs 978<br />

crore Chandrayaan-2 was<br />

launched into the space by<br />

India s heavy lift rocket<br />

Geosynchronous Satellite<br />

Launch Vehicle-Mark III<br />

(GSLV Mk III) in a text book<br />

style. After five earth-bound<br />

orbit raising activities,<br />

Chandrayaan-2 was inserted<br />

into lunar orbit. On <strong>September</strong><br />

2, Vikram separated from the<br />

orbiter.<br />

The company has launched its new<br />

processor just a few days after South<br />

Korean tech giant Samsung launched a 5G<br />

chipset of its own, the Exynos 980.<br />

Indian-origin researcher<br />

finds 419mn Facebook<br />

users exposed data<br />

San Francisco : Sanyam Jain, a security researcher and<br />

member at Hague-based non-profit organisation GDI<br />

Foundation, has discovered a massive database containing over<br />

419 million phone numbers of Facebook users on an unsecured<br />

server which were available for anyone to access.<br />

The database included 133 million records of US-based<br />

Facebook users, 18 million records of UK users and more than<br />

50 million records of users in Vietnam, TechCrunch reported on<br />

Wednesday. According to Jain, he found profiles with phone<br />

numbers associated with several celebrities.<br />

Jain found the database and contacted TechCrunch after<br />

he was unable to find the owner. After a review of the data, neither<br />

could we. But after we contacted the web host, the database<br />

was pulled offline, said the report.<br />

This latest data breach exposed millions of users phone numbers<br />

just from their Facebook IDs, putting them at risk of spam<br />

calls and SIM-swapping or SIM jacking where a mobile<br />

number is transferred to a new SIM card.<br />

This dataset is old and appears to have information obtained<br />

before we made changes last year to remove people s ability to<br />

find others using their phone numbers, a Facebook spokesperson<br />

was quoted as saying by the Engadget.<br />

After the web host was contacted, the Facebook users database<br />

was pulled offline. Some of the records also had the user s<br />

name, gender and location by country. There have been several<br />

incidents after the Cambridge Analytica episode involving 87<br />

million users where Facebook acknowledged series of privacy<br />

lapses, including the latest admission that it mishandled millions<br />

of users passwords on Instagram and unintentionally<br />

uploaded emails of nearly 1.5 million of its new users.<br />

26-foot-long dinosaur roamed the<br />

earth 72 million years ago,<br />

nearly complete skeleton found<br />

TOKYO : Japanese scientists have identified a new species<br />

of dinosaur from a nearly complete skeleton that was the largest<br />

ever discovered in the country, measuring eight metres (26 feet)<br />

long. After analysing hundreds of bones dating back 72 million<br />

years, the team led Hokkaido University concluded the skeleton<br />

once belonged to a new<br />

species of hadrosaurid<br />

dinosaur, herbivorous<br />

beast that<br />

roamed the Earth in<br />

the late Cretaceous<br />

period.<br />

A partial tail was first found in<br />

northern Japan in 2013 and later<br />

excavations revealed the entire<br />

skeleton.<br />

The team named the dinosaur<br />

"Kamuysaurus japonicus," which means<br />

"Japanese dragon god," according to a<br />

statement issued by the university.<br />

They believe the dinosaur was an adult aged nine<br />

years old and would have weighed either four tonnes or 5.3<br />

tonnes depending on whether it walked on two legs or four.<br />

The discovery was published in British peer-reviewed journal<br />

"Scientific Reports". "The fact a new dinosaur was discovered in<br />

Japan means there was once an independent world of dinosaurs<br />

in Japan or in East Asia, and an independent evolution process,"<br />

said team leader Yoshitsugu Kobayashi.<br />

Kamuysaurus japonicus probably lived in coastal areas, a rare<br />

habitat for dinosaurs at that time and the fossils also provide<br />

valuable insights into their environment. The research raises the<br />

possibility that some species of dinosaurs "preferred to inhabit<br />

areas near the ocean, suggesting the coastline environment was<br />

an important factor in the diversification" of the dinosaurs in<br />

their early evolution, the university said.
