NASA launches new weather satellite to improve forecasts

NASA launched a new, next-generation meteorological satellite at the end of the day, offering high-resolution images of storms over the Americas, which will dramatically improve weather forecasts.

The Atlas V rocket, with the GOES-S ("Geostationary Operational Environmental Satellite") satellite, took off at 17:02 local time (22:02 GMT) from Cape Canaveral, Florida.

GOES-S is the second satellite of this kind to be launched as part of a joint NASA / NOAA program.

The previous one, GOES-R, was rolled out in November 2016. experts, he helped predict the many hurricanes that hit the Caribbean last summer.

Stephen Volz, a NOAA official, explained that he had "revolutionized" the way weather forecasts are approached .

"This means that more lives are saved and better environmental information is made available to local officials," he explained.

This new generation of satellites, in which NASA and NOAA has invested $ 11 billion, to replace the current GOES satellite fleet, which has not undergone any major modernization in 40 years.

Two more GOES-R satellites built by the US group Lockheed Martin , still to be deployed.

Monitoring of fishing vessels by satellite gives new information

BIG DATA. NGOs Global Fishing Watch Sky Truth and the National Geographic Society with its Pristine Project seas as well as the American Universities of Santa Barbara and Stanford and Canadian Dalhousie, with the support of Google, pooled their skills to aggregate the billions of data provided by the satellite monitoring of fishing boats. fishing . Work that could not be done sooner. " Just a few years ago, we had neither the computing power, nor a sufficient number of satellites in orbit, nor the techniques to perform machine learning of this magnitude on large data sets, [19459014explainsinastatementBrianSullivanco-authorofthestudyfor Google Earth Outreach. All three are now at our disposal, and this has allowed us to dramatically improve our ability to follow and understand human interactions with our natural environment . "

This is indeed twenty years that the vessel monitoring system exists on a worldwide scale, at least for industrial vessels over 36 meters (in Europe the gauge is 12 meters since 2012). This monitoring is intended to combat illegal unreported and unregulated fishing which represents nearly 25 billion dollars a year. But the lack of computing power prevented you from having a global view of this activity. The results just published Science show a sector that is far from effective and sustainable

Increasing fishing effort for stagnant catches

MANAGEMENT. The exploitation of 22 billion data recorded between 2012 and 2016 gives an assessment of 70 000 registered fishing vessels cruising 55% of the surface of the seas. This represents an area four times greater than agriculture, a comparison which nevertheless deserves to be weighted: the fishing activity exploits a wild resource unlike agriculture. The energy effort is spinning. In 2016, 37 million hours of fishing were observed and the ships traveled more than 460 million kilometers "is 600 times the return distance from the Earth to the Moon ," note the researchers . The energy consumed represents 20 billion kWh per year. However, catches have stagnated for twenty years around 90 million annual tons of fish. All data are available on this graphical interface

With such precision, researchers can know the days off from fishermen around the world! But they can also see if there is a match between fishing effort and natural life cycles such as fish reproduction periods or migrations. Profitability comes at the expense of sustainable and reasonable management of the resource, note the authors of the study, although satellite monitoring reveals areas where fishing is managed properly. This is the main teaching of the study and its essential utility. Global managers now have a tool to better manage the exploitation of the marine resource. "I think most people will be surprised to learn that for vast expanses of ocean, we did not really know where the fishing was going," explains in Global Fishing's release. Watch Chris Costello, co-author of the study and economist at the University of Santa Barbara, California. This new real-time dataset will be instrumental in establishing better management of the world's oceans. "

Flood of Paris in NASA Satellite Monitor




Maryland
Unusual heavy rains flooded the eastern side of France during January 2018. Data from NASA satellites reveal which regions in France are showered with the highest rainfall.

Reporting from the NASA website on Monday (29/1/2018), the French National Weather Service has issued a flood warning for a number of areas in France.

High-intensity rainfall causes flooding in the region along the Seine River. Similar floods occurred in 2016 where water levels in the Seine reached 6 meters.

The GPM core satellite which is a joint NASA partnership with the Japan Aerospace Exploration Agency (JAXA) measures the extent of rainfall in France.

Rainfall analysis in Paris between 17-25 January 2018 was conducted at the NASA Space Flight Center in Maryland, USA. As a result, rainfall was observed evenly in some parts of France. However, the highest rainfall is found in eastern France, along the Seine River.

NASA reports the average French coastal region gets 6 inches of rain (about 152 mm). The highest rainfall recorded 180 mm for the past week.

Some areas of France with the highest rainfall include Nord-pas-de-calais, Picardy, Champagne-Ardenne, Burgundy, Center, and Franche-Comte. The region in eastern-central Switzerland also experiences rainfall of the same height.

The surface height of the Seine River is called to its peak on Saturday (27/1). The height of the river can reach 4-5 meters higher than normal.

Failure to Survive, US Spy Satellite Falls into the Indian Ocean





New York
 The US spy satellite carried by SpaceX's Falcon 9 rocket failed to survive in its orbit. The satellite is now known to have fallen into the Indian Ocean.

It was submitted officially by the US Government, as quoted from ABC News, Thursday (11/1/2018). The spy satellite, named Zuma, was launched on Sunday (7/1).

Reported by Reuters, Zuma allegedly completely lost undetected again since Monday (8/1). Intelligence satellite made by Northrop Grumman Corp. is called worth billions of dollars.

The SpaceX party says there is nothing wrong with their artificial rocket. "The rocket has done everything right," SpaceX president Gwynne Shotwell said.

"The data checked so far indicates no design, operational or other changes," he added.

SpaceX is a US space transportation company formed by billionaire Elon Musk. Scheduled SpaceX will launch Falcon Heavy, a mission that brings people into space by the end of 2018. Mentioned 'failure' Falcon 9 will not affect other SpaceX launches.

Satellite Launch Will Strengthen China's Control over the Sea of ​​Dispute

The plans of a province in China to launch 10 disputed cross-sea satellites from next year will help guide China to find key natural resources and enable rapid reaction to the movement of foreign ships, thus strengthening China's position in the top five (19659002) Sanyan Institute of Remote Sensing in Hainan province intends to launch the satellites from 2019 to 2021, the official Xinhua news agency reported in December. According to Xinhua, the launch will help surveillance with remote sensing of the disputed South China Sea and take the image of the region all the time.

China hopes to find the world's largest 3.5 million square kilometer seago fishing area before others do so, analysts said. According to their estimates, China may also use satellites to find and quickly follow up on what other nations do in the sea.

China claims about 90 percent of the marine region is based on historical records. Brunei, Malaysia, Vietnam, Indonesia and the Philippines claim a portion of the South China Sea. Since 2010, countries in Southeast Asia are increasingly wary of China, its technologically and military claimant is most advanced, as China is increasing land reclamation activities on small islands for its defense purposes.
