Is ‘Natural Flavor’ Healthier Than ‘Artificial Flavor’?

Pick up any packaged, processed food, and there’s a decent chance that one of its listed ingredients will be “natural flavor.” The ingredient sounds good, particularly in contrast to another common and mysterious ingredient, “artificial flavor.” But what exactly does natural flavor mean? When a reader posed the question, I contacted nutritionists and flavorists — yes, that’s a profession — to find out.

“Basically, if something is a natural flavor, it’s derived from some natural source,” explains Charles Platkin, director of the New York City Food Policy Center at Hunter College.

The U.S. Food and Drug Administration defines “natural flavor” as oils, resins or other extracts derived from natural sources like plants, meat or seafood. Processes like heating or fermentation are used to extract the flavor. The function of these products is flavoring, not to add any nutritional content.

“We do a lot of this in cooking,” says Chef Bruce Mattel, senior associate dean of culinary arts at The Culinary Institute of America. “Let’s say I poach shrimp in water. Then I take that big pot and reduce it all the way down to a teaspoon of shrimp essence.” That essence could then be added to a different dish. The food industry does this on a massive scale — scientists find the chemical responsible for a specific flavor in nature, extract it, and then add it to candy, beverages and throngs of other processed products.

When consumers see “natural flavor” on a beverage label, they shouldn’t assume that someone is zesting oranges into their bottle, says Mattel. Even though natural flavor must come from natural sources, it need not all come from the plant or meat whose flavor is being mimicked. For example, orange flavor might contain not only orange extract, but also extracts from bark and grass.

So if companies are trying to approximate flavors like orange, why not just use oranges? The answer comes down to availability, cost and flexibility, according to flavor chemist Gary Reineccius, of the University of Minnesota. “At one time, there were 10 times more grape-flavored products than grapes grown,” Reineccius says. “If you’re going to use all your grapes on grape soda, you don’t have any for wine. It would be exceedingly expensive. Then what do you do with the byproduct you create after you’ve sucked all the juice out of the grape?”

Flavor chemists might also want a particular kind of grape taste, he explains, and mixing the grape flavor in the lab allows them the flexibility to create exactly the flavor they want, rather than relying on farmers’ produce.

All three experts say that ultimately, natural and artificial flavors are not that different. While chemists make natural flavors by extracting chemicals from natural ingredients, artificial flavors are made by creating the same chemicals synthetically.

Platkin says the reason companies bother to use natural flavors rather than artificial flavors is simple: marketing.

“Many of these products have health halos, and that’s what concerns me typically,” says Platkin. Consumers may believe products with natural flavors are healthier, though they’re nutritionally no different from those with artificial flavors.

Nor are ingredients extracted from nature necessarily safer than something artificially made. Reineccius points out that many deadly toxins are produced in nature. What’s more, in some cases, natural flavors may have more detrimental environmental consequences than artificial flavors. Mattel explains that because natural flavors must come from resources in nature, they may involve more forest clear-cutting and carbon emissions from transport than flavors created from scratch in the lab.

Platkin suggests consumers lobby their congressional representatives to get more transparent labeling on packaging that describe exactly what the natural or artificial flavors are, so consumers are not hoodwinked into buying one product over another because of “natural flavors.”

Reineccius also offers some simple guidance: “If you like something, and it gives you the flavoring you want, you should buy it. Don’t buy it because it says ‘natural flavor.’ Buy it because you like it.”

House Republicans say the tax bill they introduced Thursday will grow the economy, create jobs and simplify tax returns, in part by eliminating tax deductions.

“Over 90 percent of Americans will be able to fill out their taxes on a postcard. That’s what simplicity means,” House Majority Whip Steve Scalise said.

But charities and nonprofit groups say that simplicity comes with a price. Even though Republicans promise to preserve the deduction for charitable donations, these groups say other proposed changes in the bill will discourage giving.

Steve Taylor, senior vice president and counsel for public policy at United Way Worldwide, notes that about a third of taxpayers currently itemize their deductions, including for charitable donations.

“Under this new proposal, only about 5 percent of people will itemize their taxes,” he says. “What that means is effectively millions of Americans that currently claim the charitable deduction will lose it.”

The Republican plan would double the standard deduction that taxpayers get in lieu of itemizing to $12,000 for individuals and $24,000 for couples, making it much more attractive not to itemize.

Una Osili, of the Lilly Family School of Philanthropy at Indiana University, estimates that change would lead to a reduction of up to $13 billion a year in charitable giving, and 28 million fewer Americans itemizing their returns. She says it doesn’t mean these people would stop giving, just that they’re likely to give less.

And, she adds, “it could disproportionately affect certain kinds of charities that draw more on the average American family,” such as churches and smaller community groups.

Tim Delaney, president and CEO of the National Council of Nonprofits, says a drop in donations is worrisome at a time when Congress is also trying to cut spending on domestic programs. His group represents 28,000 charities across the nation.

“That will lead to more people having more needs,” he says, noting that charities will be expected to pick up the slack. “We’re just concerned that this is going to overwhelm the nonprofit community.”

As a result, nonprofits are pushing Republicans to include something else in their tax plan that they say would increase charitable donations, but keep taxes simple: They want something called a universal charitable deduction, which taxpayers would get on top of the standard deduction. One proposal, by North Carolina Republican Mark Walker, would set the deduction at about $2,100 for individuals and $4,200 for couples.

One potential stumbling block is that the change could cost the Treasury several billion dollars a year, but nonprofits plan to pull out the stops in the coming weeks to make their case.

“There’s 1,150 United Ways in the United States,” says Taylor. “That means there’s at least one United Way in every single congressional district. And so over the next couple of days and into next week, those United Ways are going to be reaching out to their members of Congress.” As will tens of thousands of other nonprofits around the country.

Taylor admits they are up against a lot of other powerful interests — such as homebuilders — that will be lobbying Congress to preserve tax breaks that are important to them.

Dan Cardinali, president and CEO of Independent Sector, which represents 1.6 million nonprofits, has another concern. He notes that the Republican bill would also eventually eliminate the estate tax. Cardinali says that would discourage billions of dollars in donations from wealthy individuals who want to avoid subjecting their heirs to the tax.

Massachusetts Becomes 1st State To Ban Bump Stocks After Las Vegas Massacre

Republican Lt. Gov. Karyn Polito of Massachusetts signed a bill Friday, approved one day earlier by the state’s Democratic legislature, outlawing so-called bump stocks, accessories that allow semi-automatic firearms to mimic the rapid firing action of machine guns.

The bill’s passage makes Massachusetts the first state to enact a ban on bump stocks in the wake of last month’s shooting in Las Vegas, the deadliest in modern American history.

Authorities say the gunman responsible for the massacre, which left 58 people dead and hundreds wounded, used bump stocks to allow his semi-automatic weapons to rain down considerably more bullets on the unsuspecting crowd during the attack.

Bump stocks attach to semi-automatic weapons and enable sustained firing by using the force of the weapon’s kickback to bounce the firearm against the shooter’s trigger finger over and over.

The newly approved Mass. ban provides a 90-day grace period for bump stock owners to discard their devices.

The ban was approved with relative ease and little fanfare Friday, when Polito, acting in place of Gov. Charlie Baker who was away on vacation, signed an appropriations bill to which the bump stock ban had been added. The state legislature had passed the amended spending measure on Thursday.

In the days after the Las Vegas shooting, Baker, who is a Republican, had made clear he would support outlawing bump stocks, saying “if that were to pass tomorrow we would sign it.”

The Gun Owners’ Action League of Massachusetts, which is affiliated with the National Rifle Association and appeared to be the most vocal opponent of the new ban, spent Friday beseeching its members to call the governor’s office in an ultimately unsuccessful attempt to have the bump stock provision vetoed.

The Giffords Law Center To Prevent Gun Violence, an organization founded by former U.S. Rep. Gabrielle Giffords, who was shot and wounded at a public event in Arizona in 2011, celebrated the ban’s approval on Friday, saying in a statement they hoped other states would “follow Massachusetts’ lead.”

Massachusetts is, however, not the first state with a bump stock ban on the books. Longstanding gun regulations in California already include punishments aimed at any device that “allows the firearm to discharge two or more shots in a burst by activating the device.”

Following the tragedy in Las Vegas, in what appeared to be an unusual display of bipartisanship, Democrats, Republicans and even the NRA expressed support for some kind of regulation for bump stocks.

Multiple bills were introduced in Congress, with one in the House garnering more than two dozen signatures. But legislative momentum has stalled, as NPR’s Geoff Bennett reported in October:

“The NRA is calling for a regulatory fix for bump stocks rather than legislation. And House Speaker Paul Ryan, who first signaled an openness to considering congressional action, is now siding with the NRA. Ryan and the NRA say the best approach is for the Bureau of Alcohol, Tobacco, Firearms and Explosives, or the ATF, to regulate the devices.”

But — complicating matters further — regulating bump stocks is something many view as outside of the purview of the ATF. As NPR’s Ryan Lucas explained, U.S. law gives the ATF authority to regulate machine guns, which are defined as any weapon that can shoot more than one bullet “by single function of the trigger.”

“It is that last phrase — “by a single function of the trigger” — that is key to understanding ATF decisions, said Rick Vasquez, a firearm consultant and former acting chief of the ATF’s firearms technology branch, which conducts classification reviews.

“If a gun fires more than one bullet with a single pull of the trigger, then by law it is considered a machine gun. If, however, a gun fires only one bullet for each pull of the trigger, it is not.

“Bump stocks, Vasquez said, enable an accelerated shooting rate, but the way they are designed ensures that each pull of the trigger only unleashes one bullet. That means, he said, that they don’t qualify as machine guns under current law.”

A recent poll conducted by NPR showed “88 percent of Democrats, 77 percent of Republicans, and 82 percent of independents favor banning bump stocks. But while three-quarters of Democrats ‘strongly favor’ this kind of ban, only around half of Republicans and independents do.”

‘Weinstein effect’ ripples around the world

The British defense minister. The head of news at NPR. The co-author of “Game Change.” The head of Amazon Studios. The star of “House of Cards.”

Every day there are disturbing new allegations about prominent men abusing their power. Every day there are belated apologies and corporate consequences. Every day there are new rumors about who might be accused next.

This is the “Weinstein effect” in action, four weeks to the day after The New York Times published its initial investigation into film mogul Harvey Weinstein’s sexual misconduct.

The stories about Weinstein in The Times and The New Yorker shocked the public and started a domino effect. It was the beginning of a long-overdue reckoning about sexual assault and harassment. Private conversations about abuse are now happening publicly and globally.

Much still needs to be done to translate talk into action, to adapt cultural norms and create enforceable policy.

But many women have expressed relief that their accounts of wrongdoing are finally being heard and respected. Men have joined women in saying #MeToo, describing their own experiences of being sexually harassed or assaulted.

Companies like NPR, Netflix, Nickelodeon and institutions like the California Legislature have taken action in response to sexual misconduct allegations.

Conversations and condemnation surrounding sexual misconduct have spread beyond the United States to France, Sweden, Canada and Singapore.

Many of the cases of alleged wrongdoing involve media professionals. Recent examples of accused individuals include the actor Kevin Spacey and the director Brett Ratner.

But victims are coming forward in other industries, too, in state capitals and on college campuses. In Nashville, police are looking into allegations against a prominent music industry publicist. In New Hampshire, several Dartmouth professors are the subject of a criminal probe into possible misconduct.

Jodi Kantor, who co-authored the original Times story about Weinstein, said she hopes that part of the takeaway “is that journalism works.”

“Though the allegations we and others have brought to light are very painful, the past month speaks to what happens when journalists, sources and readers join together to ask tough questions of the powerful and make difficult topics easier to discuss,” Kantor told CNN.

It’s been less than a month since Kantor and Megan Twohey’s first Weinstein story was published. It’s anyone’s guess what another month of the “Weinstein effect” will bring.

Journalists at a variety of news organizations continue to pursue leads about alleged abuse. Some of them are household names. Others may only be known in specific industries.

The sheer number of the already-publicized cases shocks the conscience.

“Each new revelation is good. Each new revelation makes the world safer for women and for everyone else. Each is a triumph of journalism, a testament to the moral worth of dogged and empathetic reporting,” The Atlantic’s Megan Garber wrote on Thursday. “But each new revelation also exposes the reach of the shadows, the scale of the monstrosity, the depth of the lie.”

Different cases have resulted in different repercussions. Editor Leon Wieseltier was fired by Emerson Collective, where he was about to launch a new journal. Political analyst Mark Halperin lost his book deal and TV contract. Conservative commentator Bill O’Reilly was dropped by two talent agencies.

(Some harassment allegations against O’Reilly were known before October, but a New York Times story revealing a secret $32 million settlement came as a shock two weeks after the Weinstein investigation.)

Some of the consequences could be criminal in nature. Police in New York, London and Los Angeles have open investigations into Weinstein.

Gretchen Carlson, who sued Fox News boss Roger Ailes alleging sexual harassment and discrimination last year, said “this is a national epidemic that’s been silenced for too long.”

Carlson, who is now promoting a new book on the subject, “Be Fierce,” told CNN that it is vital not to lose sight of the countless women who still don’t feel able to speak out.

“I’ve been encouraging the many, many women who’ve reached out to me with their own harassment stories from all professions (waitresses to flight attendants to engineers) to take their stories public to the media so they too can receive justice — not just the high profile cases of Hollywood,” Carlson said.

Anita Hill, who 26 years ago accused her former boss and U.S. Supreme Court nominee Clarence Thomas of sexual harassment, told The New Yorker she hopes more “everyday women” will feel the effects of Weinstein’s downfall.

“People need to take this moment to make clear that this is not just about Hollywood,” Hill said.

Finnair has begun weighing passengers

This is not quite business as usual.

Finnair has just begun a new program where it weighs passengers before take-off to help the Finnish airline collect more accurate data about weights on its flights.

Paivyt Tallqvist, director for media relations at Finnair, confirmed that the airline was weighing passengers on Tuesday and Wednesday at the Helsinki airport.

“So many people actually wanted to take part in this,” she said, noting that the weigh-ins are voluntary and anonymous. “No one is forced on the scale.”

About 180 people volunteered so far, which was more than expected.

The airline launched the program, which will run intermittently into 2018, to get a more accurate picture of the average weights of the men, women and children that fly with the airline. Their carry-on baggage is also being taken into consideration and passengers must carry it onto the scale with them.

Tallqvist said it’s common industry practice to calibrate a plane based on average passenger weights provided by the European Aviation Safety Agency, which was based on research from 2009.

But Finnair said it wanted more up-to-date, relevant data to help plan its flights.

“The weight of the aircraft impacts on so many things,” including fuel levels and the speed and balance of the aircraft, said Tallqvist. “We just want to verify that the data we are using is as accurate as possible.”

Finnair is hoping to get a total of about 2,000 weigh-ins from men, women and children. It will conduct the study over the winter and spring, since carry-on baggage and coats tend to be heavier in the winter versus the spring.

Tallqvist said the airline last conducted a similar study of passenger weights in the 1980s.

Calvin and Hobbes Showed The Trouble With Organized Sports And Father Figures

In 1990, Bill Watterson created a Calvin and Hobbes storyline in which Calvin is bullied into playing baseball during recess. Watterson drew a relatable, cautionary tale about the dangers of cramming boys into neat little boxes. Everyone in this story wants Calvin to do something he hates, but even when he commits to it, nobody helps him succeed.

The storyline opens with Calvin playing alone on the swings at recess. As he swings higher and higher, the panels lose their upright rigidity and swing along with him. This is Calvin at his happiest—doing whatever he wants.

Calvin soon discovers that the swings are empty because the rest of the boys signed up to play baseball at recess. Susie, Calvin’s arch-nemesis and crush, asks Calvin if he wants to ride the teeter-totter with her since he isn’t playing baseball, and Calvin’s first reaction is defensiveness.

One strip later, Calvin has backed off his “girls have cooties” stance. He’s teeter-tottering and venting to Susie about his dislike of team sports. Susie is the only person in this storyline who takes the time to ask why Calvin doesn’t want to play baseball, and she listens to his responses rather than making it about herself.

Calvin hates the rules and restrictions of organized sports, but his explanation also suggests a lack of knowledge. He complains that, in sports, “Somebody’s always yelling at you, telling you what to do, where to be, and when to do it.” It implies a certain inexperience—people have to tell him what to do in organized sports because he doesn’t naturally know how to play them.

Whether through lack of knowledge or a dislike of structure, Calvin doesn’t gravitate toward baseball as naturally as the other boys seem to. Even Moe, as stupid and unaware as he is, notices this, and he shames Calvin for being a “sissy.” As with every other incident in Calvin and Hobbes concerning Moe, debating or reasoning with him is a zero sum game. Calvin finds himself signing up for baseball in spite of himself.

As a kid—and still as an adult, if we’re being honest—I could never swing a bat or throw a ball. My father could have taught me—he grew up in Fort Greene, Brooklyn, and played stickball as a kid—but he never did. Playing catch with him was miserable. He’d laugh at me for throwing “like a girl,” while giving me no memorable pointers on how to do anything differently. He only threw and caught, like he was waiting for my natural ability to surface. Eventually, we stopped playing.

I blamed myself for years. I assumed that throwing badly was just a natural defect that separated me from other boys. Later I blamed my father for not fulfilling one of his responsibilities as a male figure in my life. I needed a role model, someone to give me a skill that looked like it came so easily to the other boys. He knew about things I desperately needed—how to throw a ball, how to swing a bat—and giving me that knowledge would have helped me fit in.

As more time passed, I realized that my father had false expectations. It’s not that he refused to teach me; it’s that he never realized he had to. The expectations placed on boys and men to be self-sufficient prevents them from giving out help, as well as from seeking it.

Like my dad, Calvin’s dad does not refute Moe’s teasing; if anything, he reinforces it (even though neither he nor Calvin seem to know that baseball and softball are two separate things). The most ironic thing about the above strip is that in the final panel, Calvin’s dad shows some awareness of how he’s hurting his son. He laments that as an adult, he can no longer have fun and must compete, but he still places those expectations on Calvin and shows no concern that Calvin only signed up to stop getting teased.

Like my dad, Calvin’s father doesn’t offer to teach him. That evening, he suggests they “try some catches” and “practice.” He presumes, incorrectly, that Calvin knows the basics and just needs some confidence. Calvin gets hit in the face by a ball on the first play. It reminded me of playing catch with my father; instead of encouraging Calvin to try again, Calvin’s father goofs on his son for failing at a skill that he never taught Calvin to begin with.

The following morning, against Calvin’s protestations, his parents send him to school with a baseball mitt. When Calvin arrives at the baseball field for recess, Mr. Lockjaw—an educator!—is just as clueless as every other adult. It quickly becomes apparent that Calvin doesn’t know how to play, but instead of teaching him, Mr. Lockjaw just sends Calvin to the furthest corner of left field.

Out here, Calvin is disconnected from the rest of his supposed team. Nobody even tells him to switch off the field when there’s a new inning. Even though no one’s telling him what to do, he’s now treated like he doesn’t exist.

Alone, he does what he always does: retreats into his imagination. He’s roleplaying a Spaceman Spiff fantasy when the batter, against all likelihood, hits a fly ball way out to deep left field.

Unfortunately, because he didn’t know the rules, Calvin caught a ball hit by his own team. When the other boys tease him, Mr Lockjaw just lets it happen, even when the other kid threatens to hit him with the bat.

Mr. Lockjaw calls Calvin a quitter, even though he’s done nothing to help Calvin feel welcome or stop the other kids’ bullying. I’m a teacher, and we have a saying: “You enter this profession either because you had great teachers or because you had terrible ones.” Assholes like Mr. Lockjaw inspire me, by modeling what I never want to become.

The storyline ends with Calvin escaping back into his fantasy world. He and Hobbes play Calvinball, a game that has no rules and no fail state. There are two ways of looking at this ending. One is that Calvin is finally happy again, doing whatever he wants to do with his best friend.

The other way of looking at it is darker. If we work from the premise that Hobbes is imaginary, then Calvin has found his solace in talking to a stuffed tiger. And when he plays Calvinball he’s alone, with only an imaginary friend to keep him company.

There’s nothing wrong with spending time alone, of course. But there’s something sad about this particular situation, one in which several of the adults in Calvin’s life have failed him on multiple levels. What other options does he have than to be alone, when neither the adults nor the kids give him the support and emotional confidence he needs? As Calvin’s dad says, there is value in sports: learning teamwork, cooperation, and how to win and lose graciously. But Calvin doesn’t learn any of these lessons in this story arc, nor are any of the adults around him equipped to teach him.

I have a son who just turned three. I think a lot about my own father and Calvin’s dad as I’m raising him. Calvin is facing these struggles unprepared and on his own. His dad should be with him, encouraging him and teaching him. And I need to be there for my son too. Anything that I want him to know how to do, I have to teach him what to do or find someone who can. My responsibility as a father and a role model is to send him into the world prepared. And if he walks into a situation with neither the skills to accomplish a task nor the courage to ask questions and learn the task, that’s my failure, not his.

NASA’s Next Mars Rover Is Going to Be Seriously Badass

Artist’s conceptual image of the 2020 rover. (Image: NASA/JPL/Caltech)

Should all go according to plan, NASA will launch its next Martian rover in July 2020. The robotic probe is still under construction, but early signs are that the next-gen rover will be equipped with an impressive assortment of high-tech gadgets.

The rover is currently under construction at NASA’s Jet Propulsion Laboratory in Pasadena, California, and doesn’t have a name yet aside from “Mars 2020.” Like its predecessors, the future rover will scour the Red Planet for signs of previous habitability, and conduct scientific analyses of Mars’ geology, atmosphere, and other natural phenomena. But unlike those rovers that came before it, this one has a few more tricks up its metallic sleeve.

As NASA announced earlier this week, the probe will be equipped with no less than 23 different cameras. That’s 13 more than Spirit and Opportunity, and six more than Curiosity. Of its 23 cameras, nine will be dedicated to engineering tasks, seven to science, and another seven for tracking the probe’s entry, descent, and landing. These “eyes” will allow the probe to create sweeping panoramas, uncover obstacles, and study Mars in exquisite detail. Importantly, these cameras will work in tandem with the many scientific instruments onboard.

During its descent, cameras will snap photos of the parachute unfurling and as it slowly drifts down onto the planet’s red-stained surface. Once it’s out-and-about, an internal camera will peer closely at rock samples. When it’s done playing lab technician, the robot will “cache” the samples and deposit them onto the rocky surface for a future mission to collect (yes, this robot is going to be a litterbug).

The cameras will also provide more color and 3D imaging than previous missions. Whereas Curiosity had the Mastcam, the 2020 version will feature the Mastcam-z, where the “z” stands for “zoom.” The cameras will also be able to support more stereoscopic images, which are good for scanning geological features, assessing distance, and hunting for the next exploration site from far away.

The Navcams and Hazcams on the previous rovers, used for navigating and avoiding hazards, produced 1-megapixel digital images in black and white. The 2020 versions of these cameras will acquire high-rez 20-megapixel images in full color (hallelujah!). These cameras will also be able to reduce motion blurs, which means the robot will be able to snap images while zipping across the Martian surface. And because the lenses will be wider, the 2020 rover will be able to capture a broader view of the landscape.

“Our previous Navcams would snap multiple pictures and stitch them together,” said JPL’s Colin McKinney in an agency release. “With the wider field of view, we get the same perspective in one shot.”

Now, you might be thinking that full color, 3D-images filmed in high-resolution are not a big deal, but it is a big deal for a robot located 34 million miles away. With all these new gadgets comes troves of data, which then have to be beamed back towards Earth. This added equipment represents a frustrating limiting factor.

To address this, the cameras onboard the 2020 rover will compress the data (which Curiosity does as well), but another solution will be to use orbiting spacecraft as data relays. This idea was first tested during the Spirit and Opportunity rover missions, where NASA used its Mars Odyssey orbiter as an interplanetary relay station. Who says we’re not living in the future?

“We were expecting to do that mission on just tens of megabits each Mars day, or sol,” said mission scientist Justin Maki. “When we got that first Odyssey overflight, and we had about 100 megabits per sol, we realized it was a whole new ballgame.” By “sol,” Maki is referring to a single Martian day, which is 24 hours and 39 minutes long. For the 2020 mission, NASA is planning to use spacecraft already in Martian orbit, including the Mars Reconnaissance Orbiter, MAVEN, and the ESA’s Trace Gas Orbiter.

And that’s just the cameras. Other proposed scientific instruments include an X-ray fluorescence spectrometer to examine Martian surface materials, a radar imager, a microphone, an ultraviolet spectrometer, and even a Mars Helicopter Scout (HMS)—a two pound solar powered drone that would buzz above the rover, helping it to select future exploration targets.

In addition, the new rover will feature wheels that are more durable (Curiosity’s are in bad shape), have better traction, and have a performance-maximizing shape. The 2020 rover will also try to produce oxygen from Mars’ carbon-dioxide atmosphere, which could establish an important precedent for the Red Planet’s first colonists.

As to where the rover will land, that’s still not known. NASA has released a shortlist of landing sites, including Northeast Syrtis (an area once warmed by volcanic activity), the Jezero Crater (the remnant of a Martian lake), and Columbia Hills, which NASA’s Spirit lander explored during the early-to-mid 2000s.

Regardless of the site chosen, the next mission to Mars is going to be absolutely brilliant.
