Solstice sunset watch and LIGO info on our calendar this week

The calendar year is winding down, and astronomy clubs are hustling to get a last few events in before we plunge into 2017.

Rose City AstronomersThe Rose City Astronomers eschew their usual formal meeting for their annual holiday potluck at 6:30 p.m. Monday, December 19 at the OMSI auditorium in Portland. Leftovers from the event have traditionally been donated to a homeless shelter, and this year the astronomers are also collecting warm clothing for donations, figuring that astronomy folk may have a supply of such to bring comfort to those late-night sessions at the eyepiece.

The Eastside Astronomical Society will hold its monthly meeting at 7 p.m. Tuesday, December 20 at the Lake Hills Library in Bellevue. NASA Solar System Ambassador John McLaren will give a talk about the history of scientific exploration of the Sun, and look ahead to future efforts to learn even more about our nearest star.

Seattle Astronomical SocietyThe Seattle Astronomical Society will hold its monthly meeting at 7:30 p.m. Wednesday, December 21 in room A102 of the Physics/Astronomy building on the University of Washington campus in Seattle. Joey Key, a professor at the University of Washington-Bothell, will talk about the next LIGO run searching for gravitational waves, which will also involve astronomical collaboration is search of an elusive “multimessenger source,” a signal that could be detected both in gravitational waves and electromagnetic radiation. Interesting stuff!

Vikings

VMMEPPThe Viking Mars Missions Education and Preservation Project plans an informal information session for 4 p.m. Tuesday, December 20 at the Hillsdale Library in Portland. This family-friendly event will feature artifacts from the Viking mission, activities for kids, and lots of information about Viking history. Check out our recent article and podcast about the project. The year end is a good time to lend a little financial support to this great history project, too!

Solstice sunset watch

Join Alice Enevoldsen of Alice’s Astro Info and watch the first sunset of winter at 3:45 p.m. Wednesday, December 20 at Solstice Park in West Seattle. The solstice is at 2:44 a.m. PST on Wednesday. Sunset that evening is officially listed as 4:20 p.m., but Enevoldsen says they’ve noted that it’s typically about ten minutes early because of the horizon at that spot. She gives a fun and informative presentation about the mechanics of the seasons, and is persistent about it—this will be her thirty-first seasonal sunset watch. That’s a lot of solstices and equinoxes! Come by even if it’s cloudy, because the Sun sometimes sneaks through anyway, but driving rain makes it a no-go.

Preserving the stories of Viking

Rachel Tillman has a scrapbook that is out of this world. What started out as a young girl’s effort to save a cool piece of space history has morphed into a project to preserve the artifacts of the iconic Viking program and the stories of the people who made it happen.

VMMEPPTillman is the founder, executive director, and chief curator of the Viking Mars Missions Education and Preservation Project, a Portland-based nonprofit that has a huge collection of photos, documents and artifacts from the Viking missions and aims to collect oral histories of some 10,000 people who had a hand in the project—the “Vikings,” as Tillman calls them.

Little kid heaven

Her interest in the mission started early.

“My father worked on the Viking mission,” she said. He is James E. Tillman, a professor emeritus of atmospheric sciences at the University of Washington who was a member of the Viking meteorology team.

“He is an explorer; scientists often are explorers,” Tillman said of her father. “He was so engrossed in his work that lived and breathed it. He brought it home at night.”

What he often brought home was the latest problem or design or a new photo from the lander, and he would ask the kids what they thought about it. Rachel ate it up.

Viking on Mars

“I was interested from the get-go,” she said. Often she would go to her father’s office after school and soak up all of the conversations he and other scientists were having about technical matters. She’d go look it up and figure out the language, and would often make drawings about what she was learning. She made a few trips with her father to the Jet Propulsion Lab in California, and then got to go to Florida for the launches of the Viking spacecraft in 1975.

“We were down there at Cape Canaveral for the launch with Carl Sagan and Gerry Soffen and my dad and the guys from KSC,” she said. “I saw the rocket fly off.”

That’s quite a crowd for a little kid to hang out with. Rachel recalls Sagan as intense and funny, but said Soffen, the chief scientist on the Viking mission, was her hero.

“He was thoughtful, funny, very smart, absolutely wanted to know whatever it was out there to know,” she said. “He was also a magician. I’m a kid, that’s really cool!”

“The makeup of the people of the mission was amazing,” she added: Hard working, dedicated, sacrificing, funny, intelligent, grumpy, passionate—all of those things that a kid really picks up on.”

“I couldn’t have dreamed a better life than I live,” Rachel said.

They were going to melt it down

Viking was in Rachel’s DNA, but her work as a preservationist started almost as an accident.

NASA built three flight-ready Viking landers, but the first two worked and so the third—VL3—was not needed. Several groups and companies fiddled with plans to turn it into a rover, but ultimately nobody had any funding to do anything, so the lander was set aside. Then around 1979 James Tillman was looking for some used filing cabinets and found some interesting items on the NASA surplus list: his own Viking and meteorology instrument, and VL3.

VL3 at MOF

“They were scrapping it,” Rachel said. “They were going to melt it down.”

She immediately said that they had to get it and save it. Her father thought it was a ridiculous idea, but she convinced him to do it anyway because she had a ready purpose for the lander.

“We’re going to put it in my school,” she told him, “and we’re going to teach kids about robotics and about Mars and about science and engineering.”

Rachel now owns the Viking lander VL3, and it actually was at her school for a while. It also was on display for some time in the electrical engineering department at the UW. For the last ten years it has been on loan to the Museum of Flight, where it is a part of the permanent exhibit Space: Exploring the New Frontier.

“That’s how my preserving began, was with the Viking Lander,” Rachel said. Though it started with a great piece of historic hardware, Rachel is now drawn to the human side.

It’s about the people

“My role as a kid who grew up with the mission is to honor the people who did it,” she said. “Everybody. Not just the rock stars.”

Greg and Viking stuff

“Every Viking represents a child today that may want to do something like what they did,” Rachel added. “They don’t have to be the mission director, they don’t have to be the principal investigator of a science instrument, they don’t even have to be the lead engineer.”

So many other people had important functions from keeping travel schedules to crunching numbers to designing small but important components of the landers.

“All of these people are so critically important to the mission, and 95 percent of them were forgotten,” Rachel said. “That’s my job: preserve the history and the individuals; not just the timeline events, but the people who did them. That’s what this is all about.”

The Viking Mars Missions Education and Preservation Project was founded in 2008, but only really started doing any outreach in the last year. It’s been mostly underground work as Rachel met and interviewed as many of the Vikings as possible. She thought it was important to do some public events this year, the 40th anniversary of the Vikings’ landings on Mars. They held an open event in Denver—the landers were built there by Martin Marietta, which is now Lockheed Martin. NASA also held some events at Langley and at JPL, and the project held three “Science Pub” talks last month through the Oregon Museum of Science and Industry.

The future of VMMEPP

To date the project has run mostly through donations from James and Rachel Tillman, some of the Vikings, and a few others, but in the next year or so they will be doing some more serious fundraising.

“Our plan is to create a trust fund around all of the artifacts of Viking so they can’t be given away or sold,” Rachel said. “As we get new donations they will stay in this trust.”

She said the fund will help with management of the artifacts as well as preservation. Then in the next year or two they plan to issue a request for proposals from institutions and organizations that would like to host the Viking artifacts.

“They’ll have to meet the requirements that we set for care of the artifacts and for creating access to the artifacts for the public, because that’s critically important,” Rachel said.

In the meantime, the project has established an online museum, where you can go page through raw documents from the Viking missions. The project website is a treasure trove of photos and facts and stories about the Viking missions.

Rachel plans an outreach event at the Hillsdale Library in Portland for December 20, but then will probably be mostly invisible for a little while.

“Doing the oral history interviews, creating access, and protecting the artifacts, those our our three really big pushes.”

It’s a fascinating and worthy cause. If you would like to help with the preservation effort, you can donate to the project online through Facebook (through December 13) or Amazon Smile, or simply send a check to:

Club events and planetarium shows on tap for this week

The first weekend in December is heavy with club events, star parties, and planetarium shows. Here’s what’s on the calendar for the coming week:

Club gatherings

Spokane Astronomical SocietyIn December many astronomy clubs opt out of a formal meeting and instead hold a banquet or other more social gathering. The Spokane Astronomical Society plans its annual potluck dinner for 6 p.m. Friday, December 2 at the Riverview Retirement Community. A guest speaker will follow the dinner at 7:30. Dr. John Buchanan, a professor of geology at Eastern Washington University, will talk about catastrophic outburst flooding that have occurred on Earth and Mars through geologic time. He will examine how the “Ice Age Floods” in eastern Washington compare with various large floods both on Earth and Mars.

Seattle Astronomical SocietyThe Seattle Astronomical Society plans its free monthly public star parties for 6 p.m. Saturday, December 3 at two locations: Green Lake in Seattle and Paramount Park in Shoreline. Poor weather will mean cancellation of the events, so watch the club’s website and social media for updates.

Tacoma Astronomical SocietyThe Tacoma Astronomical Society will hold one of its free public nights at 7:30 p.m. Saturday, December 3 at the Fort Steilacoom campus of Pierce College. The all-weather program will be about selecting gift telescopes, binoculars, and other astronomy gear. (We covered that topic, too last week!) If the weather is good they’ll also put their gear into action for some celestial observing.

Planetarium shows

Planetaria have no trouble with cloudy weather! There are several shows on the docket for the week.

The University of Washington planetarium will host three free shows on Friday, December 2 at 5:30, 6:30, and 7:30 p.m. Reservations for all three times were snapped up quickly, but you can watch this site to see if tickets become available.

Gifts for the astronomy and eclipse buff on your list

Turkey day has come and gone, and we’ve started getting a few requests for gift ideas for astronomy enthusiasts. This year, in addition to the usual tips about books, gear, and gadgets, we’ll have a special section devoted to the total solar eclipse that will cross the United States on August 21, 2017.

Our advice doesn’t really change much from year to year. Check last year’s post Gifts for the astronomy enthusiast on your list, Gifts for the astronomy enthusiast from 2014, Picking a gift for the astronomy buff from 2013, and Choosing a gift telescope from 2012. Too busy to scrape around in the past? A few quick tips:

Visit the Seattle Astronomy Store. It’s packed with our favorite gear, books we’ve read from authors we’ve interviewed, cameras, gadgets, and accessories.

The best telescope

Smart-alecky astronomy types always say that the best telescope is the one that gets used. We tend to go with a Dobsonian reflector for outstanding bang for the telescope buck. Our personal model is the eight-inch Orion XT8 classic Dob. It’s nice on planets, super on deep-sky objects, but not so hot for photography, if that’s your thing. Dobsonians are pretty easy to set up and operate. For beginners, a good pair of astronomical binoculars can be a great tool for learning to find your way around the night sky. Get one that is at least 10×50—that’s ten times magnification and 50mm lenses. We have the Orion UltraView. Best yet, for great advice about how to choose the telescope that is right for your personal observing situation and interests, grab a copy of the classic The Backyard Astronomer’s Guide (Firefly Books, 2008) by Terence Dickinson and Alan Dyer. It’s a great reference, offers fantastic advice, and makes a fine gift in and of itself. The guide helped me get started, many moons ago, and I still use it often.

Your local experts

Cloud Break OpticsCloud Break Optics set up shop in Ballard last year, and has a fantastic showroom full of astronomy gear. They have an online store, but why non pop in and do some hands-on shopping and take advantage of their expertise and advice. Check their website for some great holiday deals. Support your local small business!

Eclipse info and swag

Next summer’s total solar eclipse will be the first to touch the continental U.S. since 1979. It’s not too early to start getting ready. That means that eclipse-related items will be welcome for most everyone. Michael Zeiler’s website The Great American Eclipse has an outstanding store through which you can purchase his fantastic eclipse maps and posters, as well as shirts, caps, sun-oculars, and other eclipse items. Get a 10-percent discount through Monday, November 28 using the code SAVE10. (Check out our article and podcast with Zeiler from earlier this year.) Eclipse glasses or viewers would make the perfect stocking stuffer this year; find them at Zeiler’s site or at the Orbit Oregon store.

Orbit Oregon has just published a children’s book called The Big Eclipse, written and illustrated by Nancy Coffelt. It and an accompanying activity book are aimed at kids from ages five to 11. These would be perfect for getting the younger set interested in the eclipse, and in science in general. It’s the only such resource we’ve encountered geared toward kids. There are a number of other books out there. Zeiler penned See the Great American Eclipse of August 21, 2017 (Great American Eclipse LLC, 2016). The book is packed with maps and information about the eclipse. We reviewed these two books earlier this month; watch for our upcoming article and podcast with Orbit Oregon’s Elaine Cuyler. In addition, Mr. Eclipse himself, Fred Espenak, has a number of eclipse books out, including Get Eclipsed: The Complete Guide to the American Eclipse (American Paper Optics, 2015) and several others shown below.

Eclipse posterAuthor, astronomer, artist, and night sky ambassador Tyler Nordgren has designed some fantastic travel posters about the eclipse, from generic nationwide posters to ones specific to some of the interesting viewing sites along the path of totality. You may have seen Nordgren’s travel posters for astronomy in National Parks and for visiting other places in the solar system. The eclipse posters are in a similar style, they’re a steal at $20 each, and they’re suitable for framing. Get them here.

Nordgren is a professor of astronomy at the University of Redlands. He was the keynote speaker at the 2014 annual banquet of the Seattle Astronomical Society.

AstroBox rocks

AstroBoxOur friend Sorin this year started a business called AstroBox; you can read the article we wrote about it in August. AstroBox is a quarterly subscription collection of cool and unique items based on a space theme. The theme for December is New Horizons: Discovering Pluto, and the box includes a cool Pluto t-shirt, a fine art print, an inflatable Pluto globe, mission patches, the AstroBox magazine filled with mission news and activities, and other goodies. Order here and use the coupon code PLUTOSA and you will get a nine-percent discount just for being a friend of Seattle Astronomy! (The coupon is good through November 30.) Plus, in the spirit of giving, for every subscription sold AstroBox will donate $1 to help restore the Pluto Discovery Telescope at Lowell Observatory. The winter AstroBox will ship in early December, so order soon!

More books

Here are a few of our other book picks for this year:

Tyler Nordgren’s new book Sun Moon Earth: The History of Solar Eclipses from Omens of Doom to Einstein and Exoplanets (Basic Books, 2016) is a delightful read. It is part travelog, part primer for the eclipse, but the best part is the history of eclipses and Nordgren’s thoughts about the development of scientific thinking. We’ve just finished it; watch for our full review soon. Nordgren will speak at Town Hall Seattle on January 14, 2017. Tickets are available online now.

Scientist Amanda Hendrix and writer Charles Wohlforth have surveyed the solar system in search of the best place for a human colony away from Earth. Their conclusion: Titan, the largest moon of Saturn, is the place to go if we have to leave the home planet. Titan has an atmosphere, suitable shielding from radiation, near limitless, cheap energy, and Earth-like features that the authors say makes it the best bet for colonization. They explain their choice in their book Beyond Earth: Our Path to a New Home in the Planets (Pantheon, 2016). It explores the economics and ethics of a move off-planet as well. The pair spoke about Beyond Earth at Town Hall recently; check our recap.

Another author paid a visit to Town Hall this year; astronaut Chris Hadfield spoke about his book The Darkest Dark (Little, Brown Books for Young Readers, 2016), a volume aimed at children trying to overcome their fears. Hadfield himself was afraid off the dark as a little kid, which could have been detrimental to a career as an astronaut had he not overcome it. Hadfield is a most engaging and entertaining speaker. Our recap of Hadfield’s talk includes a link to a music video he created in support of the book.

Julian Guthrie penned How to Make a Spaceship: A Band of Renegades, an Epic Race, and the Birth of Private Spaceflight (Penguin Press, 2016), a book about the SpaceShipOne project that won the XPRIZE competition. The tale is an interesting one about the renegades and entrepreneurs who dreamed of getting to space without the help of the government. The book includes a preface by Richard Branson and an afterword by Stephen Hawking. It’s a thrilling tale of adventure and new space.

Happy astro-shopping!

Authors pick Titan as solar system’s best place for human colony

Mars is and has long been a popular choice for human colonization should we want or need to leave Earth. But Amanda Hendrix and Charles Wohlforth say that if we’re going to go live somewhere else in the solar system, then Saturn’s moon Titan is the best choice.

Hendrix, a planetary scientist who works for the Planetary Science Institute, and Wohlforth, an award-winning science writer, have just come out with a book, Beyond Earth: Our Path to a New Home in the Planets (Pantheon, 2016). They talked about Titan and the book last week at Town Hall Seattle.

Why go?

“The topic really is not just getting to another planet, but living there and staying there self sufficiently forever,” Wohlforth said. The big question to answer, he noted, is why.

“We don’t, as human beings, normally do big expensive things for no reason at all,” Wohlforth said. “That led us to thinking about what would we want on another planet, or what we would be getting away from here on Earth, that would drive us to want to move to another planet.”

While humans have long had a case of wanderlust, Wohlforth said the reasons to colonize another planet go beyond that.

“Environment drives colonization; it has in the past, and we don’t always call it environment,” he said. “We call it overcrowding or we call it wealth seeking, but really in our society economics is how we talk about environment a lot of the time.”

A key to colonization, he said, is having the resources to do it and to keep it going.

“Making colonies requires technology and it also requires wealth and the ability to make money, and in our world that’s often meant that government gives private industry the money to get started,” Wohlforth said. “Colonies need a reason to exist environmentally or economically, they need major government investment to happen, and ultimately they need a way to support themselves without help from home.”

Why Titan

Hendrix said they developed five main criteria they considered when evaluating a place as a possible site for a human colony. It should have an atmosphere, a magnetosphere, manageable temperatures, a decent amount of gravity, and a hospitable landscape. Among those, she said the first two are most important, as the atmosphere and magnetosphere could shield colonists from harmful radiation.

Wohlforth and Hendrix

It was easy to winnow the list. Venus was rejected out of hand as a super hot hellhole with a poisonous atmosphere that may well be volcanically active.

“It’s really not the greatest environment for a human settlement,” Hendrix understated, “but what’s interesting about Venus is that in that thick atmosphere there is an altitude at which air that we like to breathe is stable. You could, in theory, have a floating city of balloons that are filled with air and where humans could live.”

On Mercury, Mars, or the Moon people would likely have to live underground to avoid radiation. That’s not very appealing, either.

“It’s not really what we’re going for,” Hendrix said. “We’d like to find a place in the solar system, if possible, where we can live on the ground and have a decent amount of radiation shielding.”

Jupiter has a lot of interesting moons, but the king of planets churns out huge doses of radiation and is not a very hospitable place. When you get out to Saturn, though, Titan catches the eye.

“One of the number-one reasons is that it has an Earth-like atmosphere,” Hendrix said. It’s mostly nitrogen with some methane, and is at about 1.5 times the pressure of our atmosphere on Earth. Titan has no magnetosphere of its own, but for much of its orbit it lies inside Saturn’s magnetosphere, so they can share.

“We think that for our key points of shielding from radiation by either an atmosphere or a magnetosphere, Titan is a very good place,” Hendrix said. “This really sets Titan apart from the other places that we looked at in the solar system for a long-term human colony.”

More positive features

We know a lot about Titan through data gathered on 124 fly-bys of this moon by the Cassini spacecraft. Titan has a lot of Earth-like features. It has clouds, rain, swamps, wind, and sand dunes. It has surface liquid—lakes and seas of methane and ethane. (Water would freeze.) It’s cold there, but Titan has pretty constant temperatures across seasons and latitudes.

There’s also a virtually limitless energy source on Titan. Reactions between its atmosphere, sunlight, and energy from Saturn create hydrocarbons that cover the moon’s surface. Colonists could drill down and get water from Titan’s liquid subsurface ocean, separate out the hydrogen and oxygen, giving them the chemistry needed to burn the hydrocarbons.

“You can imagine settlers on Titan having a power plant that takes in methane and water, and the output is energy and breathable oxygen,” Hendrix said. “So it could work out quite well for our colonists—plenty of energy.”

Don’t pack your bags yet

Setting up a colony on Titan would not exactly be a piece of cake, especially if you didn’t survive the trip. NASA has compiled a long list of potential health risks for astronauts, many of them related to radiation exposure, and concluded that space flights of more than a year are too risky for humans. It would take seven years to get to Titan with current technology.

“These are risks that, without some technology leaps,” Wohlforth cautioned, “we’re not going to Saturn. We simply can’t get there and have the astronauts be safe.”

The key to the trip is finding a way to go faster. Wohlforth said the commercial space sector is making some headway on this, and a NASA scientist named Sonny White is actually working on a propulsion system that uses quantum virtual particles and is also tinkering with a warp drive. That notion drew applause from the Trekkies at the talk, but Wohlforth noted that there’s a pretty good dose of skepticism out there. While warp drive may be “poppycock” as one headline writer opined, it’s not unreasonable to think that some smart engineer is out there cooking up a way to make space ships really zip.

Challenges aside, the urge to go and explore and colonize is strong. Hendrix and Wohlforth touched briefly on a lot of topics that are covered in more depth in the book—such considerations as how society might develop elsewhere, how reproduction might change in a Titan colony, and other challenges and opportunities.

“We really like Titan as a potential human colony location,” Hendrix concluded. “We think it has a lot to offer.”

NEOWISE, Viking, and more on the calendar this week

The Seattle Astronomy calendar is packed with interesting events this week, with something going on just about every evening. Seattle gets two talks about NEOWISE, the Mars program premieres on the National Geographic Channel, and there are several other lectures of note.

NEOWISE

NEOWISEWill an asteroid or comet one day smack into Earth again? One of the sets of eyeballs looking for Near Earth Objects (NEOs) is the Wide-field Infrared Survey Explorer (WISE). Joe Masiero, a JPL scientist with NEOWISE, will give two talks about the project this week in Seattle. He’ll speak at the monthly meeting of the Seattle Astronomical Society at 7:30 p.m. Wednesday, November 16 in the Physics/Astronomy Auditorium on the University of Washington campus. Masiero will return to the same room at 4 p.m. Thursday, November 17 for a presentation at the weekly UW astronomy colloquium. He will give an overview of the NEOWISE mission, and present some results from the latest dataset release.

Mapping the heavens

The cosmos, once viewed as stagnant, even ordinary, is now understood to be a fathomless universe, expanding at an accelerating pace, propelled by dark energy, and structured by dark matter. Theoretical astrophysicist Priyamvada Natarajan, author of Mapping the Heavens: The Radical Scientific Ideas That Reveal the Cosmos (Yale University Press, 2016), will give a talk about these ideas at 7:30 p.m. Monday, November 14 at Town Hall Seattle. Natarajan will explain the science behind some of the most puzzling cosmological topics of our time and discuss why there is so much disagreement within the science community about astronomical discoveries.

Tickets are $5 and are available online.

Preserving Viking

VMMEPPThe final of three Science Pub events about the Viking missions will be held at 6 p.m. Monday, November 14 at the Old World Deli in Corvallis, Oregon. Rachel Tillman, Founder and Executive Director of The Viking Mars Missions Education & Preservation Project, and others involved in the missions, will talk about Viking and its influence on technology and culture. The Science Pub is a program of the Oregon Museum of Science and Industry. It’s free!

If you are not able to attend this event and missed the previous ones in Portland and Eugene, fear not; Seattle Astronomy is working on a feature article about The Viking Mars Missions Education & Preservation Project. Stay tuned!

Eugene Astro

The Eugene Astronomical Society will hold its monthly meeting at 7 p.m. Thursday, November 17 at the Science Factory planetarium. The club’s mirror-grinding group will give a presentation about how reflecting telescopes’ primary mirrors are made, complete with demonstrations of the grinding process.

Cosmos on Tap

Astronomy on Tap Seattle, November 2016This month’s Astronomy on Tap Seattle event will be held at 7 p.m. Wednesday, November 16 at Peddler Brewing Company in Ballard. They’ll view episode five of the original Carl Sagan Cosmos series, complete with Cosmos bingo, trivia contests, prizes, and beer. Astronomers will discuss what’s changed, and what science has held up, since the series first aired.

Astronomy on Tap Seattle is organized by graduate students in astronomy at the University of Washington.

A home in the stars

Want to live on Mars? Maybe a bad idea. Planetary scientist Amanda Hendrix and science writer Charles Wohlforth have looked into space colonization, and suggest that Saturn’s moon Titan might be a better place. The authors of Beyond Earth: Our Path to a New Home in the Planets (Pantheon, 2016) will discuss their findings at 7:30 p.m. Friday, November 18 at Town Hall Seattle. Why Titan? It has a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy. Get the full story from Hendrix and Wohlforth; grab the book in advance.

Tickets are $5 and are available online.

Mars

MARS showOK, some may want to give Mars a shot! The television mini-series Mars premieres at 9 p.m. Monday, November 14 on the National Geographic Channel (although an online stream of the opening episode has been available online for several weeks now.) Part feature film, part documentary, the series takes a look at what a Mars mission might look like in 2033, and talks with today’s experts about the development of technology and capabilities that could make such a mission a reality. Ron Howard is an executive producer of the series, which has been directed by Everardo Gout.

TAS

The Tacoma Astronomical Society plans one of its free public nights for 7:30 p.m. Saturday, November 19 at the Fort Steilacoom campus of Pierce College. The all-weather presentation will be about the New Horizons mission to Pluto and beyond. If the skies are clear club astronomers will break out the telescopes for some observing.

Up in the sky

There’s a “supermoon” on Monday and the Leonid meteor shower peaks this week. This Week’s Sky at a Glance from Sky & Telescope magazine and The Sky This Week from Astronomy offer more observing highlights for the week.

Viking at Portland Science Pub

VMMEPPMeet some of the folks involved with the Viking Mars missions in the mid-1970s at Science Pub Portland at 7 p.m. Thursday, November 3 at McMenamins Mission Theater in Portland. As an 11-year-old girl Rachel Tillman saved the last remaining un-flown Viking spacecraft from the scrap heap. She later became founder and is executive director of the nonprofit organization The Viking Mars Missions Education & Preservation Project. Tillman will speak at Science Pub Portland, along with Al Treder, who worked on Viking guidance and control; Pat DeMartine, Viking lander command sequence and simulation programmer and science team member; and Peggy Newcomb, wife of NASA Viking engineer and author John Newcomb, who passed away in March.

Suggested donation for admission is $5. Science Pub Portland is a program of the Oregon Museum of Science and Industry. If you can’t make this Viking Mars Mission event, it will be repeated at Science Pub Eugene on November 10 and Science Pub Corvallis on the 14th.

Saving the planet

When the Large Synoptic Survey Telescope comes online, it is expected that the discovery rate of near-Earth asteroids will increase by more than a factor of 20 over the current rate, and that the list of asteroids with a worrisome probability of hitting the Earth will also become much larger. Astronaut Ed Lu, CEO and co-founder of the B612 Foundation, will discuss the scientific as well as public policy challenges related to potential asteroid impact scenarios at this week’s University of Washington astronomy colloquium. The event will be held at 4 p.m. Thursday, November 3 in the Physics/Astronomy Auditorium on the UW campus in Seattle.

Club meetings

The Tacoma Astronomical Society will hold its monthly meeting at 7:30 p.m. Tuesday, November 1 in room 175 of Thompson Hall on the University of Puget Sound campus in Tacoma. Topics will include a review of some of the club’s new gear and a primer on Proxima b, a roughly Earth-sized planet believed to be in orbit around our nearest stellar neighbor.

The Spokane Astronomical Society will hold its monthly meeting at 7:30 p.m. Friday, November 4 at the planetarium at Spokane Falls Community College. Specific topics or guest speakers for the gathering had not been published as of this writing.

Star parties

There are three star parties on the calendar for this week. The Covington Community Park Star Party is planned for 8 p.m. Friday, November 4 at the park. The event is a joint effort of the Seattle Astronomical Society and the Boeing Employees’ Astronomical Society.

The Seattle club also plans its free monthly public star parties for 6 p.m. Saturday, November 5 at two locations: Green Lake in Seattle and Paramount Park in Shoreline. Cloudy weather will mean cancellation of the star parties; watch the club’s website or social media for updates.

Tacoma Astronomical Society will hold one of its free public nights at 7:30 p.m. Saturday, November 5 at the Fort Steilacoom campus of Pierce College. The indoor program will be about spectroscopy. If the weather is clear they’ll break out the telescopes and have a look at what’s up in the night sky.
