Ahead of this week’s launch of SpaceX’s Crew Dragon spacecraft, NASA is working to keep the enduring threat of COVID-19 at bay during the historic launch. To protect its astronauts, ground crew, and potential visitors, NASA has adjusted their approach to this highly anticipated event. If successful, the launch will not only break the US’s nine-year drought of crewed launches to the ISS, but it will also make history as the first time a private spacecraft has carried people into orbit.
“We’re taking extra precautions,” said Steve Stich, deputy manager of NASA’s Commercial Crew Program, during a press call this month. On the ground, the agency is introducing temperature checks and physical distancing at Mission Control.
A successful launch requires dozens of people who usually work in close quarters in closed rooms at Mission Control. For this launch, NASA is spreading them out between different rooms. “We need to make sure we are separating people as much as possible,” he said. They’ll disinfect rooms regularly and put up Plexiglas between different work stations. “We’re looking at all the things where we can practice the guidelines for social distancing, and at the same time, launch this very important mission to the International Space Station,” he said.
Those measures are important to protect both this launch and the next set of NASA missions. “We have other missions that need to go forward. We don’t want to risk the health of the people who work at Kennedy,” said NASA Administrator Jim Bridenstine on a press call in May. The Mars Perseverance Rover launches in July.
Extreme caution is already being taken with the Crew Dragon’s astronauts. Bob Behnken and Doug Hurley have been in quarantine since May 13th. That’s a normal part of the preparations for a mission — crews heading to space always quarantine for a period of time before a launch to minimize the chance that they’re taking an infectious disease of any kind into space. As an extra step, both Behnken and Hurley will be tested for the novel coronavirus twice before they leave for the ISS. Anyone interacting with the astronauts before the launch will wear masks and gloves and have their temperature taken.
“We don’t anticipate that between now and the day of launch that there’s really going to be an opportunity for them to contract any virus or harmful bacteria,” Bridenstine said.
In addition to protecting the astronauts and ground crew, NASA is also limiting the number of visitors who can come to the space center to watch the launch, Bridenstine said. The VIP list for this particular event is very short. They’re not closing dignitaries out entirely — some members of Congress and of the National Space Council will be in attendance. They won’t be able to bring along staffers, though. “We’re really trying to whittle it down to what is important,” he said.
Sadly, the cheering crowds that were a feature of past missions didn’t make the cut. In 2011, the last time astronauts launched into space from US soil, nearly 1 million people packed close together on bridges and beaches in Cape Canaveral, Florida to watch. NASA hopes that won’t happen this time. “We’re asking people not to travel to the Kennedy Space Center,” Bridenstine said. “We think it’s in the best interest of the agency and in the best interest of the nation if people join us by watching from home.”
“It is a shame — NASA and SpaceX have worked so hard to get to the day, and the American public has come along this long journey with us,” said Gwynne Shotwell, president and chief operating officer of SpaceX, on a press call this month. “But it’s the right thing to do.”
NASA can only control what people do on its own property, though. It’s up to the state of Florida to regulate roads and beaches — and the county sheriff is encouraging people to come watch the launch, despite the risks of large gatherings.
“We are not going to keep the great Americans that want to come watch that from coming here,” said Brevard County Sheriff Wayne Ivey in a press conference. “If NASA is telling people to not come here and watch the launch, that’s on them. I’m telling people what I believe as an American. And so NASA has got their guidelines, and I got mine.”
Ahead of the launch, businesses and restaurants are opening across the state of Florida, where nearly 50,000 cases of COVID-19 have been identified. Despite the relaxation of stay-at-home orders in Florida and other nearby states, public health experts still recommend people avoid large groups and crowded spaces, where the disease spreads easily. The Centers for Disease Control and Prevention notes that traveling by air, car, or bus increases someone’s chances of contracting and spreading COVID-19.
Even with the change in audience and spectacle, the nuts and bolts of the launch will continue as planned. Stich says teams at NASA have run simulations that include all of the extra COVID-19 precautions, and they’ve gone smoothly. “We don’t really see any impact how we’re gonna operate on launch day,” he says.

SpaceX delays first historic crewed launch to space due to weather
After getting down to just 17 minutes until launch, SpaceX had to postpone its first crewed flight to space on Wednesday afternoon due to bad weather over the launch site in Florida. Now, the two passengers on board SpaceX’s capsule — NASA astronauts Bob Behnken and Doug Hurley — will disembark the vehicle and try again on Saturday, May 30th.
Nearly two dozen attorneys general sue Trump administration over controversial fuel standard
The Trump administration was sued by attorneys general from 23 states and the District of Columbia over the controversial rolling back of Obama-era fuel standards. A coalition of environmental and health groups also filed suit today over the rollback. It’s the latest legal battle in President Donald Trump’s efforts to undo Obama-era plans to cut back on air pollution and greenhouse gas emissions.
In March, Trump finalized a rule that would require car manufacturers to make their new fleets 1.5 percent more fuel efficient each year, setting a goal of reaching an average of about 40 miles per gallon by 2026. That’s a much lower bar than what was set during the Obama administration, which would have pushed automakers to ramp up fuel efficiency by 5 percent each year in order to reach an average of 54 miles per gallon by 2025.
The lawsuit alleges the Environmental Protection Agency and National Highway Traffic Safety Administration used a flawed analysis to justify their rollback. The agencies did not immediately respond to a request for comment. The Trump administration has argued that the Obama-era standards would have made cars more expensive, forcing people to stick with older, less-safe models. But the attorneys general point to evidence that the weaker rules could result in an estimated thousands of premature deaths because of increased tailpipe emissions.
“What makes [Trump’s] rule so offensive is [that the Obama-era standard] is not a rule where people can say it was a disconnect. No, this was a smooth path,” Colorado Attorney General Phil Weiser said on a press call. “This was a promising path. This was a future that we need. But nonetheless, we’re seeing this happening.”
The Obama-era standards had already saved vehicle owners $86 billion at the gas pump and reduced planet-heating carbon dioxide by half a billion metric tons, according to the EPA. The new standards, on the other hand, could add up to an additional 2 billion barrels of oil and nearly an additional 1 billion metric tons of carbon dioxide. That’s about as much as 257 coal-fired power plants would put out over a year.
“Just read the text of the rule and you will discover that it is a job-killer and public health hazard,” California Attorney General Xavier Becerra said in a statement. “It will increase costs to consumers and allow the emission of dangerous pollutants that directly threaten the health of our families.” The battle over cleaner cars and air is playing out as COVID-19 strikes people with respiratory diseases especially hard, the attorneys general pointed out in today’s call.
Car companies are split over what fuel efficiency standards should be. Volkswagen, Ford, Honda, and BMW last year committed to year-over-year gains in fuel economy that exceed Trump’s weakened standards. General Motors, Toyota, and Fiat Chrysler, on the other hand, have backed Trump’s bid to revoke California’s ability to set state vehicle emissions standards higher than the federal mandate.
Ford said today that it is neither joining the suit nor defending the Trump administration’s new rule. “We have chosen a different path in support of a voluntary framework in California,” it said in a statement. “The voluntary framework gives more regulatory certainty which protects the long-term interests of the industry, affordability, consumers, and the environment.”
Emergency COVID-19 vaccines will have to convince a skeptical public
During the 2009 H1N1 pandemic, Sandra Quinn asked hundreds of Americans if they’d be willing to take a hypothetical vaccine that was authorized for emergency use but wasn’t formally approved by the Food and Drug Administration. Most were hesitant: Quinn, the senior associate director of the Maryland Center for Health Equity at the University of Maryland, found that only around 8 percent of people said that they’d definitely take the vaccine.
An emergency H1N1 vaccine never came to be, but the questions Quinn asked 10 years ago are back in the spotlight today, as pharmaceutical companies in the US and around the world fight to produce a coronavirus vaccine as quickly as possible. It’s a real possibility that the FDA could allow for emergency use of a vaccine this time around. The United States Department of Health and Human Services (HHS) said that it aims to have doses of the AstraZeneca vaccine candidate by October — and that “emergency use authorization or licensure of this vaccine from the U.S. Food and Drug Administration (FDA) would be required to make the vaccine available.”
Far more than 8 percent of people would probably line up for an emergency coronavirus vaccine: the virus that causes COVID-19 is a much larger threat to most people than H1N1, which didn’t trigger a societal shutdown and was far less deadly. But people’s concerns and misconceptions around experimental products haven’t gone away, and they will have to be addressed in the lead-up to any emergency use of a coronavirus vaccine.
“It’s going to be a critical point going forward,” Quinn says.
Authorization isn’t approval
If a pharmaceutical company develops a vaccine that it wants to distribute in the United States, it has to send mountains of data about it to the FDA. The agency carefully reviews that data and decides if there was clear enough evidence that it was safe and effective to approve it.
A coronavirus vaccine won’t necessarily have to go through that process. The country has been under a public health emergency since the end of January, which means that the FDA can authorize a vaccine for emergency use as soon as there’s a signal it might be effective and that its benefits outweigh the risks. It’s faster than the regular approval process, but the bar is lower: the agency just has to find that it may be effective.
The FDA has already given emergency use authorization to companies making diagnostic tests, antibody tests, and treatments for COVID-19. The same law that lets the agency sidestep the usual process during an emergency can also be used for vaccines. “The capability exists,” says Alison Bateman-House, a bioethicist and assistant professor in the department of population health at the NYU Grossman School of Medicine. “It was meant to be used for vaccines, otherwise there would have been a specific carve-out.”
The FDA would have to be more cautious with vaccines than it has been in issuing emergency authorization for drugs, though. Drugs, for the most part, are given to people who are already sick. Vaccines, on the other hand, are intended for people who are healthy. “You always have a greater burden when doing something to a healthy person versus trying to intervene on behalf of a sick person,” Bateman-House says.
The agency should have data showing that a vaccine can help prevent disease (not just that it helps people produce antibodies) and clear data on at least short-term safety, former FDA officials told the Pink Sheet. Bateman-House told The Verge that she’d be comfortable with an emergency vaccine authorization — with stipulations. “There’d have to be a really good reason you couldn’t just push through the normal way, and the evidence would have to look good,” she says.
The US is trying to speed vaccines through clinical trials as quickly as possible through Operation Warp Speed, which includes a program called Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) through the National Institutes of Health. In July, this program will test vaccine candidates on tens of thousands of people who sign up for clinical trials. The trials will look for evidence that the vaccines can blunt the spread of the virus in areas where it’s still spreading.
Experts think the October timeline proposed by HHS and AstraZeneca is unrealistic. It’ll take at minimum four or five months for researchers to have enough data to tell if people who receive the vaccine are less likely to catch COVID-19. But once that data starts to come in, if it’s promising, the FDA could go through with an emergency authorization.
Trust and consent
Creating an effective vaccine takes a herculean effort, but getting one across the finish line isn’t the only challenge. In order for a vaccine to beat back the pandemic, people have to actually agree to take it. If a vaccine is authorized by the FDA for emergency use, it’s vital that each person taking the vaccine understand exactly what it is — and isn’t. “You have to make sure someone understands that this is not an FDA approved vaccine, like the ones you’ve taken your entire life,” Bateman-House says. “Given the severity of the situation, we don’t have anything better, and we’re going to allow this product to be used.”
The challenge is, Quinn’s research shows that most people don’t have a good sense of the difference between drug approval and emergency authorization. She found that Americans have a limited understanding of FDA terminology around experimental products. “People don’t understand that kind of language,” she says. In one survey, she found people were unfamiliar with terms like “emergency use authorization,” “off-label” (which is when a drug is used for different disease than the one it was approved for), and “investigational new drug” (a drug that’s being tested in clinical trials).
Tagging a vaccine as an experimental product or something that’s being offered for emergencies only could also make people less likely to trust it. People had negative associations with terms like “experimental,” “investigational new drug,” and “emergency use authorization,” Quinn’s survey found. Half of people asked about a hypothetical, experimental H1N1 vaccine said they would be very or extremely worried about it.
People may be more willing to override their concerns about unproved or emergency use vaccines now than they said they were during the 2009 H1N1 pandemic. Those who said they were more affected by H1N1 were more likely to say they’d take an emergency vaccine, and nearly everyone in the US has been touched by COVID-19 — either by the illness directly or by the shutdowns.
“The perceived severity of the disease is going to be quite different. That could make a difference in terms of willingness to take a vaccine, but it’s an open question,” Quinn says.
Anti-vaccine sentiments, though, are stronger than they were in 2009, and there’s less trust in the government more generally. “This constant erosion over the last several years of trust and science and trust in experts, we’re seeing it on a daily basis right now. That’s a dramatic difference from 2009,” she says.
Willingness to take an emergency vaccine would also vary between racial and ethnic groups. During the 2001 anthrax attacks, for example, the Centers for Disease Control and Prevention offered postal workers who may have been exposed to the bacteria the option of taking an investigational form of the anthrax vaccine that could prevent illness. Most people didn’t take that offer — and African American workers were particularly resistant.
“It was an immediate red flag,” Quinn says. Many of the postal workers cited the 1932 Tuskegee syphilis study as the reason why they didn’t trust experimental products. During that study, the US withheld syphilis treatments from black men. Government scientists let them suffer through the course of the disease in the name of research. The erosion of trust in science from the black community has never fully recovered. Quinn’s H1N1 survey also found that black and Latino respondents were less likely to say that they’d take an emergency vaccine.
If historic distrust of scientific research leaves those communities less likely to take a vaccine if it’s offered under emergency use, vaccination gaps could contribute to the already devastating racial disparities in the impact of the COVID-19 pandemic, Quinn says. The virus is already devastating black communities: the majority of COVID-19 deaths are in disproportionately black counties.
The FDA will be under enormous pressure to authorize a vaccine as soon as possible. Without one, COVID-19 will stay a looming threat. An emergency authorization may be the best path forward, Bateman-House says, but there could be long-term consequences to public trust in vaccines. If a vaccine is tagged as something that regulators allowed to be distributed without as rigorous a review, people who are already skeptical of vaccines might take it as evidence that vaccines are risky or dangerous.
“If you hear that the government is pushing out a vaccine, and it’s not fully approved, that hits all the cognitive dissonance you already have,” she says.
If there end up being side effects from an emergency vaccine, even if they’re minor or far less severe than COVID-19 itself, that could be additional ammunition for people who are already suspicious of vaccines. The ramifications could be significant and are important to consider.
“People tend not to think of vaccines in isolation. They think of them as a group. If there’s suspicion of a COVID-19 vaccine, there will be suspicions of other vaccines,” Bateman-House says. “When you’re making this decision, you have to be aware that it could have a multi-year fallout.”
