«Breaking News» China’s new spy satellite will use lasers to light up the ocean

China's new spy satellite 'Project Guanlan' could use lasers to spot submarines up to 1,600ft (500m) below the ocean's surface. 

These lasers will be so powerful they will make the upper layer of the sea 'more or less transparent', according to scientists involved in the project. 

Researchers claim these artificial laser beams could be one billion times brighter than the sun.

However, some experts say this type of deep-sea surveillance is 'mission impossible' as lasers are fundamentally unable to penetrate that deep. 

China's new Project Guanlan satellite uses lasers to spot objects deep under water. In theory when a laser hits an object - such as a submarine - pulses bounce back and are picked up by sensors, which can determine the size, shape and location of the object

Project Guanlan, which means 'watching the big waves' was launched in May at the Pilot National Laboratory in Qingdao in Shandong, writes South China Morning Post.

Its components are being developed by more than 20 universities across the country.

For more than half a century naval researchers have been attempting to create a laser using Lidar (a portmanteau of 'light and 'radar.').

In theory when a laser hits an object - such as a submarine - pulses will bounce back and be picked up by sensors, which will be able to determine its shape.

According to researchers, this high-powered laser beam is so powerful it would be able to scan an area as wide as 62 miles (100km) on land.

It will also be used alongside microwave radar which will scan the surface of the water and identify surface movement.

This could be an indication that a submarine is lurking below.  

Lidar uses ultraviolet, visible, or near infrared light to image objects. 

It can be used with a wide range of targets, including non-metallic objects, rocks, rain, chemical compounds, aerosols, clouds and even single molecules.

However, it is negatively affected by fog, murky water and marine life. 

It also works less well in water as light scatters when it hits the surface.

Researchers say the aim of the project is to strengthen Chinese surveillance.

Song Xiaoquan, who is involved in the project, said it will make the upper layers of the ocean 'more or less transparent'.

He said it 'will change almost everything'.

Dr Xuaiquan said he did not know when the satellite would be ready.

However, not everyone is convinced and some say it is 'impossible' to use the technology to look 1,600ft below the ocean's surface.

'They [project researchers] won't be able to break through the darkness guarded by Mother Nature – unless of course they are Tom Cruise, armed with some secret weapons,' one anonymous researcher from the Shanghai Institute of Optics and Fine Mechanics at the Chinese Academy of Sciences told SCMP.

WHAT IS LIDAR TECHNOLOGY AND HOW DOES IT WORK?

Lidar is a remote sensing technology that measures distance by shooting a laser at a target and analysing the light that is reflected back.

The technology was developed in the early 1960s and uses laser imaging with radar technology that can calculate distances.

It was first used in meteorology to measure clouds by the National Center for Atmospheric Research.

The term lidar is a portmanteau of 'light and 'radar.'

Lidar uses ultraviolet, visible, or near infrared light to image objects and can be used with a wide range of targets, including non-metallic objects, rocks, rain, chemical compounds, aerosols, clouds and even single molecules.

A narrow laser beam can be used to map physical features with very high resolution. 

This new technique allowed researchers to map outlines of what they describe as dozens of newly discovered Maya cities hidden under thick jungle foliage centuries after they were abandoned by their original inhabitants.

Aircraft with a LiDAR scanner produced three-dimensional maps of the surface by using light in the form of pulsed laser linked to a GPS system. 

The technology helped researchers discover sites much faster than using traditional archaeological methods.

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.

Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
