NASA has always been a fantastic existence. As a NASA with $ 20 billion in Trump's funding, people around the world are curious what they are doing.

NASA seems to be doing some weird things like daily posting of nebulae, high-definition beauty of the planet, space mission of Musk's SpaceX, NASA Technical Report detailing rocketship technology and Google AI Technology found "second solar system".

除了发现开普勒

Yes, just east of time on December 14, NASA officially announced a star around the discovery of a planetary system composed of eight planets - Kepler 90 system, scientists have for the first time discovered a and the solar system The same 8-planet galaxy. And this discovery can not do without the help of Google AI, the use of Google's machine learning to analyze Kepler space telescope data, to achieve a higher analysis efficiency.

Unexpectedly, AI also participated in NASA's development of the vast Xinghai. In fact, NASA has long used AI to do a lot of things.

AI is a gimmick? Is NASA Google's sponsorship fee?

NASA, which is aiming to be the star of the sea, has been a staunch supporter of technology, with the Hollens at the International Space Station, astronauts using HTC's Vive and Manus VR gloves, and the fate of AI dating back to 2010 or even earlier.

In 2010, NASA sought a partnership with Boston University in the hope of adding AI brains to robotics to work with low-pixel sensors. Later, Neurala, a startup from Boston University, developed a Mars brain for NASA that allowed NASA's Mars rover to quickly sense nearby objects with sensors and run on basic local computing environments.

Later NASA began crazy cooperation projects with various technology companies, such as "Quantum Artificial Intelligence Laboratory" set up with Google and the Frontier Development Lab (FDL) with Intel.

In its partnership with Google, NASA used Google's Tango technology to create three AI-controlled UAVs called Batman, Joker and Nightwing, autonomous movement using depth sensor + wide-field camera with map positioning, visual inertia Ranging do motion tracking to avoid obstacles. NASA also hosted a human-and-AI drone competition that, despite its defeat, attracted "a lot of attention" to the concept of "drone driving."

As for Intel, it assumed the task of protecting the cosmic security with NASA. While not disclosing too much information, NASA said at a FDL sharing session that training AI with historical data such as solar storms, meteor showers, etc. ideally identifies the possibility of a dangerous situation from everyday data. Intel should be in charge of data training. This time with Google also found Kepler 90, NASA provides data, Google provides power. NASA even said that Google and Google should study whether there is any extraterrestrial existence in the universe.

In this light, NASA research using artificial intelligence seems to have some "retreat". However, it is a very publicity point for companies to get along with NASA, extraterrestrial life and defensive universe. The two sides hit it off, with one providing funding and fortune, and the other aiming to reclaim unlimited data in the universe.

Method is more important, AI is the universe class hegemony

So for astronomy, the universe in this area of ​​work, in the end is not suitable for the application of artificial intelligence technology?

The answer is of course.

First, owing to the high cost of manned people, the danger coefficient is large, such things as cosmic exploration and planetary exploration are unmanned.

Second, a large part of NASA's work is analyzing imagery of sensor backhaul images, and analyzing images is, of course, the best work of artificial intelligence.

Third, the other is aviation. The field of astronomy is a field of digitization and informationization. It is suitable for mining historical data and training various algorithmic models that help scientists work.

In the case of discovering a new planet, this time it was discovered that the Kepler 90 applied the Lingri method, that is, the change in the brightness of the star by observing the planets flying in front of the star and blocking some of the stars. But it will affect the brightness changes not only planets, there will be sunspots and so on.

Google researchers chose to throw the problem to a black box, train the convolutional neural network using the light curve data of planetary systems found in previous Kepler telescopes, and then go through the telescope-based data obtained by the resulting model to eventually assist scientists in discovering Kepler 90.

About this discovery, what matters is not just the result but the method. The Google team said it took only two hours to train the model with historical data. Such a speed of learning is completely incomparable with humanity. It seems that with the help of Artificial Intelligence, we hope to complete the analysis of hundreds of billions of stars in the Milky Way as soon as possible. Perhaps we can find the vision of extraterrestrial life and find another Earth in science fiction movies so that during our lifetime Realized?

In its lifetime, you can enjoy the AI ​​technology from NASA

In the lifetime of can not see the aliens are not necessarily, but we will be in life, we can use the "NASA produced" new technology.

Although NASA is obsessed with the stars, technologies that have been validated in aviation work are slowly coming to the civilian market.

For example, NASA's Jet Laboratory and the U.S. Department of Homeland Security jointly developed the AUDREY system, where firefighters can steer first responders safely by collecting fire temperature, gas and other hazardous signal data.

For emergency responders, eliminating the need to rely on their own fifth sense of fire escape route, AUDREY can monitor when they predict the resources they need and help them escape from the flames.

And NASA's satellite remote sensing technology not only accurately identifies global pollution, but also extracts a great deal of data from image recognition, such as the number of trees on Earth. Now the same technology has been applied to many fields such as environmental protection, agriculture and so on.

So, regardless of NASA to use alien to find aliens is not a gimmick, it is important that NASA is making new technologies continue to germinate, mature, let AI in space while walking into our lives.
