In this climate, John W. Austin approached financier Joseph A. Bower, a Detroiter, in Bower’s offices at the Liberty National Bank in New York City. Austin was an officer of the Detroit Graphite Company, and his aim was to secure a contract to paint such a bridge as might, inevitably, span the Detroit River. Their meeting spawned a remarkable accomplishment – a $23.5 million, privately financed link between the United States and Canada. As the two men met above the din of Manhattan’s streetcars and crowds, they talked of heavy construction and high finance. They could not have foreseen their role in a most curious event in Detroit’s history.
As SpaceX charges forward with full and rapid rocket reuse, the company's stretch goal is to fly each "ship" every six to eight hours. These "ships" are the Starship launch system's upper stage, which is 50 meters tall and designed to carry payloads into orbit or be refilled there to fly to the Moon or Mars. The first-stage "booster" could fly even more frequently, as much as once an hour, he predicted. The first stage makes a six-minute flight to space and back and is intended to be loaded with propellant on the ground in just 30 minutes. //
SpaceX has unquestionably come a long way since 2016, when Musk first revealed the full scope of his plans to build a launch system that could establish a self-sustaining settlement on Mars. By his own estimates, such a venture would require 1 million tons of food, water, and construction materials. The settlers will need to build an entire industrial base to mine the red planet, and manufacturing consumer products will require a huge infrastructure base to refine and shape materials.
This is an incredible logistical challenge. Consider that throughout the last five decades, during the entirety of its Mars exploration program, NASA has landed a grand total of a couple of tons on the surface of Mars.
For his settlement plan, therefore, Musk proposed an unprecedented rocket and spacecraft. During a 90-minute speech in Guadalajara, Mexico, five years ago, Musk spoke of his “Interplanetary Transportation System,” or ITS. This was a huge and fully reusable launch system with a second-stage spaceship that could be fueled in low Earth orbit and then flown to Mars fully laden with supplies or dozens of settlers. Eventually, after more name changes, the ship would be christened Starship.
The 2016 speech was striking in its candor. Musk laid bare his entire vision for the first time for all the world to see. It was easy to criticize, and many did. The general viewpoint among the established space community at the time was that such a vision was preposterous.
And who could blame the critics? Only four weeks before Musk gave his speech, SpaceX had blown up its second Falcon 9 rocket in a year, losing the Amos-6 satellite on the launch pad on September 1. The company was also going to be years late delivering a Crew Dragon capability to NASA and its astronauts. And for all the talk of reusable rockets, SpaceX had not yet re-flown a single Falcon 9 rocket. Critics watched the Guadalajara speech and saw Musk the Charlatan—over-promising, grasping for government money, and spewing lies about the future when he couldn’t deliver in the present.
But in the five and a half years since Musk’s first Mars moment, the billionaire has answered those critics. SpaceX has not lost a single rocket since Amos-6. In fact, the Falcon 9 booster recently set the record for the longest streak of successful launches by any rocket ever. SpaceX also has become a reliable provider of crew transportation services to NASA, years ahead of its competitor Boeing, which NASA paid 60 percent more for the same service to low Earth orbit. And Falcon 9 rocket first stages have now flown 11 times, with no end in sight.

Introduction
Yes, yes...it's yet another set of instructions for constructing your very own digital coaxial to optical converter. First off, why you would need such a device - you have a sound source with a coax digital output, and a digital recorder that accepts optical input (in most cases, everyone's favorite - the minidisc recorder). Total cost for this project will run $25-$30.
Now, does recording digitally make a difference? I would say that while analog recording sounds fine for general use, digital recording is very nice for devices where you would be better off bypassing the DACs. Digital to analog converters do exactly as they say - take digital values and produce a proportional analog voltage to feed your speakers/headphones. //
COVID will affect cardiovascular health, health care for years to come, authors say.
A bout of COVID-19 can take a hefty toll on the heart and blood vessels; people who recover from the infection have substantially higher risks of developing any of 20 serious cardiovascular disorders in the year following their recovery. Those disorders include heart failure, stroke, atrial fibrillation and other arrhythmias, myocarditis (inflammation of the heart), and blood clots in the lungs.
Cardiovascular risks increase with the severity of an infection—that is, people who need intensive care for COVID-19 face the highest cardiovascular risks. But, overall, the pandemic virus appears to be indiscriminate, wreaking havoc on cardiovascular systems and increasing risks in all groups of patients, from those with mild disease, to the young, to those without underlying conditions or pre-existing cardiovascular diseases.
Even the Speaker admits her veto of GOP members is ‘unprecedented.’
When Speaker Nancy Pelosi announced her plan for a House Select Committee to investigate the Jan. 6 Capitol riot, she reserved eight members as her choice and left five for Minority Leader Kevin McCarthy. Well, scratch that. On Wednesday she vetoed two of Mr. McCarthy’s choices as unacceptable.
Contrarians can be useful! Yes, we’re very rude people, but sometimes we can help you avoid making a mistake. There’s a reason why the Catholic Church, when considering whether somebody should be made a saint, used to bring in a Devil’s Advocate.
The Catholic Church of liberal wisdom is The New York Times. But if you work at the Times, you probably exist in an epistemological safe space into which no adverse information ever flows. You may never even hear about certain true things; the information doesn’t penetrate the media outlets you read, the dinner parties you attend or the podcasts you listen to at the gym. //
Bennet lives in a world where everyone “knew” Palin’s team had a “clear” link to the shooting. He had probably read so many left-wing columns and blogs blaming Palin that he simply internalized the information and didn’t bother to check it. The fact-checker glossed over the false assertion also, because she was too overworked to do her job. (“I was checking things fast on deadline … my reading of it led me not to have looked at that specifically . . . I did the best of my ability in the time that I had.”) //
Funnily enough, when I worked at People magazine, where a team of hatchet-faced fact-checkers who made IRS auditors look like friendly Labradoodles would spend my Monday nights haranguing me over every adjective and preposition [.... ] anything that had previously been reported in the New York Times was considered a “red check,” i.e., unassailable truth.
At the Times itself? You can call one of the most prominent political figures an accessory to attempted murder, and the only sound you’ll hear is people shrugging.
For all The Times stories bemoaning that Americans increasingly live in “bubbles” of “misinformation,” it never seemed to look at the bubble inside its own newspaper. //
Hey, I just thought of someone who’d be perfect for the job: experienced in daily journalism, familiar with Times protocols, yet disinclined to automatically believe every vicious assertion about anyone on the Right: Her name is Bari Weiss. Maybe give her a call.
