Starlink Musk satellite-based high-speed internet network, asks for permission to test its user devices on ships - SpaceX's Starlink high-speed connection network project, the aerospace company of Elon Musk, wants to test on ships the devices that users will have to connect to their network, so it has asked for authorization from the US Federal Communications Commission (FCC), as reported by CNBC.

In particular, the company Musk will use 10 ships to perform pilot testing of the connection with this network has already around 650 satellites and according to early tests conducted by its employees would be able to offer connections of 100 megabits per second with a latency low enough to play online games, and a download capability that would allow watching movies in streaming, high definition. The company has been recruiting volunteers to test the service since June.

The authorization requested by the aerospace company, which is pending approval, states that it will deploy ten ground stations on as many ships, two of them autonomous platforms, over a period of two years.

Where does SpaceX get the ships? The company already has several ships, which are used to retrieve the capsules of the rockets that drive the launches and then come off, falling into the sea once completed its mission.

Starlink is one of Musk's big business Stakes, which plans to generate a profit of between 26,000 and 44,000 million euros per year with this high-speed internet project transmitted from satellites, for which it would be necessary to have at least a thousand of them in orbit, according to the company's founder himself told several media outlets, including Business Insider.

It currently has about 650 satellites in orbit, after a few weeks ago breaking the record number of satellites launched by any company or space agency in a single month, with the launch of 175 of them in the last three launches. With this progression, it could reach 1,400 satellites by the end of the year, something that also raises concern among scientists about the accumulation of satellites in Earth orbit and the difficulties it entails for research, space debris that is generated and interference with large telescopes.

However, the number of satellites is not the only difficulty of the project. The cost of connection devices and their size is another element that Starlink needs to address in order to attract customers. "I think the biggest challenge will be with the user terminal and make the cost of the user terminal affordable. That will take us a few years to figure it out, " Musk told Aviation Week in May. It also faces regulatory difficulties in the United States, where it wants to use parts of the electromagnetic spectrum that several companies want to use to provide services.

The founder of Tesla is not the only one interested in offering internet from space, since this August Amazon obtained the approval by the FCC of its 'Kuiper Project', a plan to launch 3,236 satellites to transmit internet from space, in which he plans to invest about 8,700 million euros.

The goal of the company led by Jeff Bezos is to deploy between 12,000 and 24,000 satellites —more than the whole of humanity has ever launched— for a battle that for the e-commerce giant aims to bring the Internet to the most remote areas and expand the digital customer base.

SpaceX and Amazon are not the only ones in this race, which has already had losses, such as OneWeb, a project with investment from Airbus, Qualcomm and Virgin that even launched 74 satellites, but had to declare bankruptcy last March. Canadian Telesat expects to have 78 satellites in orbit in 2022 and 220 in 2023, according to SatelliteToday.

The gateway to coronavirus in Spain was the Basque Country, according to new research

The SARS-CoV-2 virus entered Spain through the city of Vitoria on 11 February.

He is the holder of the latest research carried out by the scientists of the University of Santiago de Compostela Antonio Salas and Federico Martinon in an article of the Journal Zoological Research. The study, published this Thursday, identifies the genetic strains that originated virtually all cases of COVID - 19 in Spain, all from a trace that goes back to Euskadi.

Thus, the work interprets that there are a total of 5 main lineages that account for almost 90% of all incidents in the genome database. These would be A2a5 (38.4%), B3a (30.1%), B9 (8.7%), a2a4 (7.8%) and A2a10 (2.8%), all with different patterns of genomic variation.

Through the strain b3a, says the research, the focus started in Basque territory would have succumbed in an important wave of expansion between 5 and 19 March, dates in which it would have expanded throughout the Spanish geography. For its part, the a2a5, the second most important lineage of the virus in Spain, would have its origin in Italy - the great non-Asian epicenter of the pandemic - where its evolutionary ancestor, the A2A, the most frequent in the whole globe, arose.

The latter would have arrived in Spain later than the B3a, in early March, and quickly became strong in Madrid, from where it spread to the rest of the communities. Many of these lineages, whether those generated within Spain or those imported from abroad, would have crossed borders and controls to the United Kingdom (B3a) and South America (b3a or A2a4), mainly.

The group of researchers led by professors from the Faculty of Medicine and the Institute of sanitary Research (IDIS) of Santiago de Compostela represents a great find to understand the behavior of the virus in Spain, which weeks after the first infection would become one of the major global foci of the first wave of COVID-19 worldwide.

Thus, to understand it from the point of view of the causative agent, the team of researchers analyzed a total of 41,362 genomes of which 1,245 made up the Spanish sample. With these data, the study becomes the largest case of global research conducted to date in relation to the genomic variability of SARS-CoV - 2 in the world and the first published in the exploration of genetic variation in Spain.
