SpaceX Confident About Its Starlink Constellation for Satellite Internet; Others, Not So Much

Despite technical glitches, SpaceX plans to launch the first of nearly 12,000 satellites in 2019

SpaceX has, of course, been ferrying quite a bit of stuff into space lately. [See “Musk vs. Bezos: The Battle of the Space Billionaires Heats Up,” in this issue.] But last February, SpaceX launched two small satellites of its own. They were for an initial test of gear intended for use in a globe-spanning broadband data network, called Starlink, made up of thousands of small satellites. SpaceX CEO Elon Musk nicknamed the two test satellites Tintin A and Tintin B, after the beloved Belgian cartoon character known for his adventures. And just as their fictional namesake often did, the satellites ran into unexpected troubles.

After launch, Tintin A and B were supposed to propel themselves from their initial orbital altitude of 511 kilometers to their final operational orbit of 1,125 km. But the satellites remained in their initial orbits; SpaceX has never been clear about why. (SpaceX declined to comment for this story.)

Fires at recycling sorting facilities, ignited by combustible materials in the waste stream, can cause millions of dollars in damage, injuring workers and first responders and contaminating the air.

Detecting the blazes early is key to preventing them from getting out of control.

Mayo Clinic researchers have developed an artificial-intelligence algorithm that can detect weak heart-pump functioning from a single-lead electrocardiogram (ECG) on the Apple Watch. Early results indicate that the ECG is as accurate as a medically ordered treadmill stress test but could be performed anywhere, the researchers say.

The single-lead AI algorithm was adapted from an existing algorithm that works by analyzing ventricular pumping data from a 12-lead ECG already in clinical use under an Emergency Use Authorization from the U.S. Food and Drug Administration (FDA).
