There’s no place like home—unless you’re Elon Musk. A prototype of SpaceX’s Starship, which may someday send humans to Mars, is, according to Musk, likely to launch soon, possibly within the coming days. But what motivates Musk? Why bother with Mars? A video clip from an interview Musk gave in 2019 seems to sum up Musk’s vision—and everything that’s wrong with it.

In the video, Musk is seen reading a passage from Carl Sagan’s book Pale Blue Dot. The book, published in 1994, was Sagan’s response to the famous image of Earth as a tiny speck of light floating in a sunbeam—a shot he’d begged NASA to have the Voyager 1 spacecraft take in 1990 as it sailed into space, 3.7 billion miles from Earth. Sagan believed that if we had a photo of ourselves from this distance, it would forever alter our perspective of our place in the cosmos.

adam Kinzinger is a liberated individual—liberated from his party leadership, liberated from the fear of being beaten in a primary, liberated to speak his mind. The 43-year-old representative was one of 10 House Republicans who voted to impeach Donald Trump for inciting the attack on the U.S. Capitol.

“I don’t have a constitutional duty to defend against a guy that is a jerk and maybe says some things I don’t like,” Kinzinger told me, explaining what had pushed him to finally break with the president. “I do when he’s getting ready to destroy democracy—and we saw that culminate on January 6th.”

This was the sort of language a number of Republicans used in the immediate aftermath of the riot. “The president bears responsibility for Wednesday’s attack on Congress by mob rioters,” House Minority Leader Kevin McCarthy said on January 13. But by the end of the month, McCarthy was traveling hat in hand to Mar-a-Lago to meet with Trump.

Every day, more than 1 million American deltoids are being loaded with a vaccine. The ensuing immune response has proved to be extremely effective—essentially perfect—at preventing severe cases of COVID-19. And now, with yet another highly effective vaccine on the verge of approval, that pace should further accelerate in the weeks to come.

This is creating a legion of people who no longer need to fear getting sick, and are desperate to return to “normal” life. Yet the messaging on whether they might still carry and spread the disease—and thus whether it’s really safe for them to resume their unmasked, un-distanced lives—has been oblique. Anthony Fauci said last week on CNN that “it is conceivable, maybe likely,” that vaccinated people can get infected with the coronavirus and then spread it to someone else, and that more will be known about this likelihood “in some time, as we do some follow-up studies.” CDC Director Rochelle Walensky had been no more definitive on Meet the Press a few days before, where she told the host, “We don’t have a lot of data yet to inform exactly the question that you’re asking.”

When the polio vaccine was declared safe and effective, the news was met with jubilant celebration. Church bells rang across the nation, and factories blew their whistles. “Polio routed!” newspaper headlines exclaimed. “An historic victory,” “monumental,” “sensational,” newscasters declared. People erupted with joy across the United States. Some danced in the streets; others wept. Kids were sent home from school to celebrate.

One might have expected the initial approval of the coronavirus vaccines to spark similar jubilation—especially after a brutal pandemic year. But that didn’t happen. Instead, the steady drumbeat of good news about the vaccines has been met with a chorus of relentless pessimism.

We are living in a time of bad metaphors. Everything is fascism, or socialism; Hitler’s Germany, or Stalin’s Soviet Union. Republicans, especially, want their followers to believe that America is on the verge of a dramatic time, a moment of great conflict such as 1968—or perhaps, even worse, 1860. (The drama is the point, of course. No one ever says, “We’re living through 1955.”)

Ironically, the GOP is indeed replicating another political party in another time, but not as the heroes they imagine themselves to be. The Republican Party has become, in form if not in content, the Communist Party of the Soviet Union of the late 1970s.

I can already hear the howls about invidious comparisons. I do not mean that modern American Republicans are communists. Rather, I mean that the Republicans have entered their own kind of end-stage Bolshevism, as members of a party that is now exhausted by its failures, cynical about its own ideology, authoritarian by reflex, controlled as a personality cult by a failing old man, and looking for new adventures to rejuvenate its fortunes.

The end of the coronavirus pandemic is on the horizon at last, but the timeline for actually getting there feels like it shifts daily, with updates about viral variants, vaccine logistics, and other important variables seeming to push back the finish line or scoot it forward. When will we be able to finally live our lives again?

Pandemics are hard to predict accurately, but we have enough information to make some confident guesses. A useful way to think about what’s ahead is to go season by season. In short: Life this spring will not be substantially different from the past year; summer could, miraculously, be close to normal; and next fall and winter could bring either continued improvement or a moderate backslide, followed by a near-certain return to something like pre-pandemic life.

At about 2 a.m. on Thursday morning, I woke to find my husband shivering beside me. For hours, he had been tossing in bed, exhausted but unable to sleep, nursing chills, a fever, and an agonizingly sore left arm. His teeth chattered. His forehead was freckled with sweat. And as I lay next to him, cinching blanket after blanket around his arms, I felt an immense sense of relief. All this misery was a sign that the immune cells in his body had been riled up by the second shot of a COVID-19 vaccine, and were well on their way to guarding him from future disease.

Side effects are a natural part of the vaccination process, as my colleague Sarah Zhang has written. Not everyone will experience them. But the two COVID-19 vaccines cleared for emergency use in the United States, made by Pfizer/BioNTech and Moderna, already have reputations for raising the hackles of the immune system: In both companies’ clinical trials, at least a third of the volunteers ended up with symptoms such as headaches and fatigue; fevers like my husband’s were less common.

On its face, reinfection appears to be a straightforward term. It is literally “infection, again”—a recovered person’s second dalliance with the same microbe. Long written into the scientific literature of infectious disease, it is a familiar word, innocuous enough: a microbial echo, an immunological encore act.

But thanks to the pandemic, reinfection has become a semantic and scientific mess.

Newly saddled with the baggage of COVID-19, reinfection has taken on a more terrifying aspect, raising the specter of never-ending cycles of disease. It has sat at the center of debates over testing, immunity, and vaccines; its meaning muddled by ominous headlines, it has become wildly misunderstood. When I ask immunologists about reinfection in the context of the coronavirus, many sigh.

Why wouldn’t someone want a COVID-19 vaccine?

Staring at the raw numbers, it doesn’t seem like a hard choice. Thousands of people are dying of COVID-19 every day. Meanwhile, out of the 75,000 people who received a shot in the vaccine trials from Pfizer-BioNTech, Moderna, AstraZeneca, Johnson & Johnson, and Novavax, zero died and none were hospitalized after four weeks. As the United States screams past 500,000 fatalities, the choice between a deadly disease and a shot in the arm might seem like the easiest decision in the world.

Or not. One-third of American adults said this month that they don’t want the vaccine or are undecided about whether they’ll get one. That figure has declined in some polls. But it remains disconcertingly high among Republicans, young people, and certain minority populations. In pockets of vaccine hesitancy, the coronavirus could continue to spread, kill, mutate, and escape. That puts all of us at risk.

The world of Danish children’s television is not for the prudish. Kids who turn on the tube in Denmark might be greeted by gratuitous flatulence, cursing, casual nudity, or cross-dressing puppets. One show centers on a pipe-smoking pirate who wallops ninjas and flirts with Satanism. In another, an audience of 11-to-13-year-olds asks probing questions about the bodies of adults who disrobe before them. As Christian Groes, an anthropologist at Denmark’s Roskilde University, told me, Danish children’s television is not unlike an LSD trip: “Everything is possible in that universe,” he said, loosely quoting a friend, “and people won’t complain about it.”

But people did complain when the Danes debuted a kids’ animated series in January featuring a protagonist with an absurdly long, prehensile penis.
