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 />
the communication links.<br />
Meanwhile all is not lost as<br />
far as the Rs 978 crore<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 />

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.
