'Martians Abroad' Is An Optimistic Look Into Humanity's Future


'Martians Abroad' Is An Optimistic Glance Into Humanity's Future

  22 HOURS AGO
Mars has been on a lot of minds lately. The success of Andy Weir's science fiction novel The Martian — and Ridley Scott's subsequent film — helped rekindle interest in the Red Planet. And now, National Geographic's TV series Mars is going even further in giving us a plausible look at what a Martian colony in the near future might look like.
It's perfect timing, then, for the publication of Martians Abroad. The novel is the latest from New York Times bestselling author Carrie Vaughn, best known for her Kitty Norville urban fantasy series. But rather than involving werewolves in modern-day America, Martians Abroad sets its sights on the human-colonized solar system of tomorrow.
That said, most of Martians Abroad — as the title states — doesn't take place on Mars at all. The majority of the action takes place on Earth. Polly Newton is a typical teenager — that is, a typical teenager living on Mars' Colony One, where her mother is the director of operations. She sends Polly and her twin brother Charles to Earth to attend Galileo Academy, a prestigious school full of the scions of the most powerful families in the solar system. Polly and Charles are the first Martians to enroll at Galileo, partly because Mars is less wealthy and seen as a bit of a hick planet. (Not that Polly wants to go to Earth in the first place — she's forced to abandon an upcoming internship as a starship pilot, something she desires more than anything.)
Polly's reluctance turns to ambivalence after she and her cliquish classmates — with whom she has plenty of friction — have to defend themselves against mysterious peril at Galileo. A conspiracy is afoot at the school, and Polly and her peers are the target.
It's a setup familiar to any Harry Potter fan, but Vaughn keeps the intrigue at a leisurely simmer, giving Polly enough space to gradually cope with the travails of a new planet. Born and raised on Mars, her body is thin and frail compared to the muscular Earth kids who are accustomed to three times the gravity she's used to. And another kind of gravity starts to bear on her: the responsibilities of becoming a good student, a good sister, and ultimately, a good leader.
Despite being mostly set on Earth, Martians Abroad offers plenty of particulars about the potential for living on Mars in the future. In lavish, well researched detail, Vaughn paints a vivid portrait of technological advances and pioneering spirit.
What she doesn't do is slather her vision in grit. Countering the current trend of dystopian science fiction, Martians Abroad is hopeful, thoughtful, and fun. Polly's universe isn't a perfect one, but neither does Vaughn feel the need to put her into the most miserable situation imaginable; the action, like the angst, is predominantly light. Even when Polly dreads going to Earth, which she assumes will be "old, grubby, crowded, archaic, backward, stifling," she strives to adapt and make the best of her situation. And the feminist overtones of the story are subtly handled. She's surrounded by a futuristic society full of confident, capable women — whom she desperately wants to emulate.
Martians Abroad is a refreshingly optimistic change of pace, but it makes no secret about its precedents. It's an open homage to Robert Heinlein's juveniles, as his novels with adolescent protagonists were called — and one of those juveniles in particular, 1963's Podkayne of Mars. The parallels are numerous. Heinlein's heroine goes by the nickname Poddy. Her brother's name is Clark. And they're both sent abroad from their Martian home.
It's this loving, retro-futuristic vibe that helps make Martians Abroad so endearing. Harking back to a more innocent time — but without downplaying the tribulations of contemporary adolescence — Vaughn has crafted a tribute to the power of science fiction, evoking a giddy sense of wonder and adventure about space exploration, technology, and human ingenuity. And, yes, even about being young.

Student Rocketry Teams To Compete For FAR-MARS Prize

Student Rocketry Teams to Compete for FAR-MARS Prize

MOJAVE, CA – Student-built rockets will streak into the stratosphere in Spring 2018 as college and university engineering teams from around the world compete for $100,000 in prizes in a contest sponsored jointly by 
the Mars Society, headquartered in Lakewood, CO and the California-basedFriends of Amateur Rocketry (FAR), officers announced today.

The FAR-MARS Prize will grant $50,000 to the team whose bi-propellant liquid-fueled rocket comes closest to reaching 45,000 feet (13,716 meters). A second $50,000 prize will go to the team that comes nearest to hitting that same altitude with a rocket powered by liquid methane and liquid oxygen, announced Dr. Robert Zubrin, president of the Mars Society, and Mark Holthaus, director and treasurer of FAR. “If one team can achieve both goals with the same rocket, they’ll win both prizes totaling $100,000,” Holthaus said.

The contest launch window will commence Saturday, May 5, 2018, the 57th anniversary of the launch of 
Alan Shepard, America’s first man in space, and continue through Sunday, May 13th, according to Holthaus and Dr. Zubrin. The goal of being the closest to 45,000 feet, rather than simply reaching the highest altitude, was chosen so teams would have to demonstrate the precise control required to create reusable launch vehicles, Holthaus said.

“We see this as a logical follow-on to the Orteig Prize of the 1920s that sparked aviation and the X Prize of the 2000s that jump-started commercial spaceflight,” said Dr. Zubrin, founder of the Mars Society and author of the book The Case For Mars, which proposed the Mars Direct manned missions that radically changed ideas about the feasibility of interplanetary space travel in the 1990s. “We’re looking to get college and university students fired up about rocketry, which is the key to space travel and making humanity a multi-planetary species.”

Funds for the prize have been provided by an anonymous donor whose goal is to advance Science, Technology, Engineering, and Mathematics (STEM) education in general and human spaceflight specifically, Holthaus and Dr. Zubrin said.

The $50,000 for each part of the prize will be presented to the college or university sponsoring the winning team, to be used for scholarships for students in the STEM fields related to rocketry.

Teams will have about 15 months to design, build and test their rockets before gathering at the FAR rocket launch complex called FAR Site, located north of Edwards Air Force Base, on May 5, 2018.  “Each competing rocket must loft a 2.2 pound (one-kilogram) payload, containing an altitude tracking device, to the target altitude,” Holthaus said. “The payload will be supplied by FAR, rockets must be recovered by parachute, and these rockets are required to clear 30,000 feet (9,144 meters) as a minimum to qualify.” The competition will continue over two weekends (May 5-6 and 12-13) if needed, Holthaus noted.

FAR Site is equipped with static engine test stands and rocket launch rails so competing teams can try out their engines and rockets and tweak their performance pre-competition, Holthaus added.

Participating teams must be composed of college or university students, with at least one faculty advisor providing guidance, Holthaus said. Teams from the United States and other countries are encouraged to enter and compete; two or more institutions can combine students, faculty and resources for a single entry.

“We see the ability to design, build and test bipropellant liquid-fueled rockets as a key career skill in the coming decades, with a host of new, innovative aerospace companies such as SpaceX, Blue Origin and Orbital ATK taking spaceflight in entirely new directions,” Dr. Zubrin said. “Using methane as a fuel is a critical component for missions to the planet Mars, as it is easy to create liquid methane out of the resources already available on that world.”

Details on how to enter the contest and the exact rules for the competition will be posted on the Mars Society and FAR websites in the near future.

The Mars Society is the world's largest and most influential space advocacy organization dedicated to the human exploration and settlement of the planet Mars. Established by Dr. Zubrin and others in 1998, the group works to educate the public, the media and government on the benefits of exploring Mars and creating a permanent human presence on the Red Planet.

Friends of Amateur Rocketry, formed in 2003 by amateur rocketry enthusiasts, whose mission is to educate the public STEM fields through the use of amateur rocketry; and to foster rocket technology by supporting individuals, hobbyists, student groups, businesses and other like-minded non-profit entities. Both the Mars Society and Friends of Amateur Rocketry are registered 501(c)(3) non-profit organizations.
