Space startup Lynk uses satellite to send text message to unmodified Android phone



An aerospace startup that plans to launch hundreds of satellite tv for pc “cell towers” into house says it has efficiently despatched a textual content message to a typical Android smartphone utilizing one in every of its satellites in orbit. The corporate claims it’s the primary time a textual content message has ever been despatched to an unmodified cell phone from house, and it demonstrates the expertise wanted to offer international cellphone connectivity from orbit.

The corporate behind the breakthrough house textual content known as Lynk, which used to go by the title UbiquitiLink. Lynk is one in every of a number of house firms in the meanwhile planning on constructing a constellation of hundreds of satellites to offer some form of connectivity to people on the bottom. However relatively than present broadband web protection, Lynk is targeted on offering cell service for the typical cell phone with its satellites, with out the necessity for patrons to offer any further {hardware}.

“Nobody ever in human historical past has used a satellite tv for pc to ship a message on to an unmodified cell phone on the bottom,” Charles Miller, co-founder and CEO of Lynk, tells The Verge. To be able to get service from a satellite tv for pc now, individuals must both purchase a specialised satellite tv for pc telephone or buy an adjunct that permits a typical smartphone to hook up with a automobile in orbit. The Lynk group say they’ve developed software program for his or her satellites that “tips” the typical cellphone into connecting with the autos orbiting overhead at any time when the telephone is out of vary of an everyday cell tower.

To check out this expertise, Lynk launched its third take a look at payload to the Worldwide Area Station in December aboard a SpaceX Falcon 9 rocket. Astronauts on board the ISS then hooked up the payload to a Cygnus cargo spacecraft on the skin of the station. The Cygnus indifferent from the ISS on January 31st and has lingered in orbit ever since, permitting the Lynk group to check out their expertise. And on February 24th, Lynk despatched its first textual content with the payload, a message that learn “It is a take a look at” (although the primary three letters have been really lower off within the message for some purpose). It was obtained by an Android telephone positioned on the Falkland Islands whereas the Cygnus capsule handed overhead.

Miller says it was an important expertise demonstration that permits Lynk to maneuver ahead in constructing out its constellation. “We expect if we are able to get the regulators to log out, and with the help of our cellular community companions, there’s no purpose tactically that we are able to’t implement the primary international providers by the top of the yr,” says Miller. The plan is to start out launching Lynk’s mini-satellites, which weigh about 55 kilos (25 kilograms) and can orbit at about 310 miles (500 kilometers) excessive. The corporate is able to offering business providers with just some dozen satellites, however to offer 4G protection, Lynk might want to launch hundreds of its small autos. Quite a few considerations have been raised concerning the sorts of impacts these constellations can have on the house atmosphere, however Miller says Lynk’s footprint shall be smaller than different constellations as its satellites are pretty tiny.

Miller’s goal with Lynk is to basically flip all present cellphones into satellite tv for pc telephones, with out requiring shoppers to buy any further add-ons. As a substitute, present cellular community operators would purchase this functionality from Lynk and supply it of their buy plans to clients — making it a seamless course of for the typical cell phone consumer. It’s this technique that units Lynk other than different mega-constellation operators, equivalent to SpaceX or OneWeb. To be able to patch into these mega-constellations, clients might want to purchase particular gear referred to as “consumer terminals” to obtain sign relays from the satellites. With Lynk, the cell phone is the consumer terminal, says Miller.

Regardless of these variations, Miller says Lynk isn’t in direct competitors with these different mega-constellations and even standard mobile networks. The purpose is to offer international cell service at any time when an individual is out of vary of all these different choices. “Once you stroll away from the Wi-Fi in your house or that [user terminal] antenna and also you’re disconnected, you then’ll use us,” says Miller. “So we complement every part that they don’t cowl.”

However identical to different mega-constellations, Lynk’s purpose is similar: present connectivity to the world, particularly areas the place individuals are out of vary of cell towers or don’t have many connectivity choices. “You’re speaking immediately 5 billion clients who want your service in some quantity — some extra, some much less,” says Miller. One main purpose of Lynk is to offer “Everybody All over the place Emergency” alerts to anybody on the globe, warning individuals of potential disasters equivalent to tsunamis, hurricanes, and extra.

In the end, Miller argues what Lynk is doing is extra vital than racing to 5G. “What we’re doing is basically bringing connectivity to greater than a billion individuals who have zero connectivity; that’s life altering,” he says.

“We expect that’s a very massive deal — as massive or an even bigger deal than 5G.”

FDA authorizes first antibody-based test for COVID-19



The Meals and Drug Administration has issued its first authorization for a COVID-19 check that appears for antibodies within the blood, somewhat than for the virus within the nostril or throat. Whereas the antibody strategy means this check could have limitations, it’s an necessary device that would assist in the response to the pandemic.

The check is produced by the biotechnology firm Cellex. Well being care suppliers have to attract blood from a affected person’s vein to run the check, and it may well solely be executed in licensed labs — not a health care provider’s workplace. It takes 15 to 20 minutes to get a consequence.

When somebody is contaminated with a virus for the primary time, their immune system begins producing antibodies particular to that virus. Checking to see if somebody has coronavirus-specific antibodies is nice proof that they’ve been contaminated. Nevertheless, the physique doesn’t begin to make these instantly, and they may not seem till somebody’s sickness has run its course. In consequence, antibody-based checks can inform docs whether or not somebody has already had COVID-19, however they’re not pretty much as good at testing if the affected person presently has it.

Nonetheless, the FDA authorization signifies that the company thinks the advantages of getting the check out there outweigh the dangers. “It’s cheap to imagine that your product could also be efficient in diagnosing COVID-19,” the company wrote within the letter, which approved the check for emergency use.

The FDA was already permitting firms to make and distribute antibody checks for COVID-19 with out formal authorization. Nevertheless, with out approval, they weren’t in a position to declare that their check may diagnose the illness.

Even when they’re not nice diagnostics, antibody checks are critical in the response to the pandemic. They’d assist determine who has already been sick — whether or not they had important signs or not — and subsequently, who might be immune sufficient to the virus to securely transfer around the globe usually. They’ll additionally assist public well being officers perceive how a lot of the inhabitants has been contaminated by the coronavirus. Dozens of firms are working to develop antibody checks, as are researchers at the Centers for Disease Control and Prevention.

The US struggled to ramp up COVID-19 testing, and it’s nonetheless laborious for individuals to entry checks. Although there have been over 1 million checks run within the US, a milestone President Trump highlighted earlier this week, the testing charge per capita continues to be far behind different international locations. An simply out there antibody check would give individuals who weren’t in a position to get examined once they have been sick an opportunity to know if they really had COVID-19.
