British telecom major Vodafone today said it plans to create the first 4G network on the moon to support a mission by PTScientists in 2019. "The moon will get 4G coverage next year, 50 years after the first NASA astronauts walked on its surface.

 Vodafone plans to create the first 4G network on the moon to support a mission by PTScientists.

We have target to land in 2019 on Moon," a Vodafone representative said. The company has appointed Nokia as its technology partner for the 4G network . "This will be the first privately-funded moon landing mission. It will lay the future of space exploration.

The cost less than what it cost for full mission lab. We will be below USD 50 million mark," Robert Bohme, CEO and Founder of PTScientists said. Berlin-based PTScientists is working with Vodafone Germany and Audi on the project. Mission to the moon is due to launch in 2019 from Cape Canaveral on a SpaceX Falcon 9 rocket, Bohme said.

Vodafone testing indicates that the base station should be able to broadcast 4G using the 1800 MHz frequency band and send back the first ever live HD video feed of the Moons surface, which will be broadcast to a global audience via a deep space link that interconnects with the PTScientists server in the Mission Control Centre in Berlin.

 The project will last for about 11 days because of massive change in temperature on the moon, Bohme said.

A 4G network is highly energy efficient compared to analogue radio and that will be crucial to Mission to the Moon and is the first step to building communications infrastructure for future missions, Bohme said.

Vodafones network expertise will be used to set up the Moons first 4G network, connecting two Audi lunar quattro rovers to a base station in the Autonomous Landing and Navigation Module (ALINA), as per the details shared here .

Nokia, through Nokia Bell Labs, will create a space-grade Ultra Compact Network that will weigh less than one kilogram --the same as a bag of sugar.

 The 4G network will enable the Audi lunar quattro rovers to communicate and transfer scientific data and HD video while they carefully approach and study NASAs Apollo 17 lunar roving vehicle that was used by the last astronauts to walk on the Moon to explore the Taurus-Littrow valley in December 1972.

The Mars Colour Camera (MCC) onboard ISRO's Mars Orbiter Mission has captured the image of Phobos, the closest and biggest moon of Mars.

The image was taken on July 1 when MOM was about 7,200 km from Mars and 4,200 km from Phobos.

"Spatial resolution of the image is 210 m.

This is a composite image generated from 6 MCC frames and has been color corrected," ISRO said in an update along with the image.

Phobos is largely believed to be made up of carbonaceous chondrites.

According to ISRO, "the violent phase that Phobos has encountered is seen in the large section gouged out from a past collision (Stickney crater) and bouncing ejecta."

"Stickney, the largest crater on Phobos along with the other craters (Shklovsky, Roche & Grildrig) are also seen in this image," it said.

The mission also known as Mangalyaan was initially meant to last six months, but subsequently ISRO had said it had enough fuel for it to last "many years."

The country had on September 24, 2014 successfully placed the Mars Orbiter Mission spacecraft in orbit around the red planet, in its very first attempt, thus breaking into an elite club.

ISRO had launched the spacecraft on its nine-month- long odyssey on a homegrown PSLV rocket from Sriharikota in Andhra Pradesh on November 5, 2013.

It had escaped the earth's gravitational field on December 1, 2013.

The Rs 450-crore MOM mission aims at studying the Martian surface and mineral composition as well as scan its atmosphere for methane (an indicator of life on Mars).

The Mars Orbiter has five scientific instruments - Lyman Alpha Photometer (LAP), Methane Sensor for Mars (MSM), Mars Exospheric Neutral Composition Analyser (MENCA), Mars Colour Camera (MCC) and Thermal Infrared Imaging Spectrometer

Google has indexed invite links to private WhatsApp group chats, meaning anyone can join various private chat groups (including several porn-sharing groups) with a simple search.

According to a report in Motherboard, invitations to WhatsApp group chats were being indexed by Google.

The team found private groups using specific Google searches and even joined a group intended for NGOs accredited by the UN and had access to all the participants and their phone numbers.

Journalist Jordan Wildon said on Twitter that he discovered that WhatsApp's "Invite to Group Link" feature lets Google index groups, making them available across the internet since the links are being shared outside of WhatsApp's secure private messaging service.

"Your WhatsApp groups may not be as secure as you think they are," Wildon tweeted on Friday, adding that using particular Google searches, people can discover links to the chats.

According to app reverse-engineer Jane Wong, Google has around 470,000 results for a simple search of "chat.whatsapp.com", part of the URL that makes up invites to WhatsApp groups.

WhatsApp spokesperson Alison Bonny said: "Like all content that is shared in searchable public channels, invite links that are posted publicly on the internet can be found by other WhatsApp users."

"The links that users wish to share privately with people they know and trust should not be posted on a publicly accessible website," Bonny told The Verge.

Danny Sullivan, Google's public search liaison, tweeted: "Search engines like Google & others list pages from the open web. That's what's happening here. It's no different than any case where a site allows URLs to be publicly listed. We do offer tools allowing sites to block content being listed in our results."
