Science Fiction: news & updates

In 1971 at Caltech (I was there), Bruce Murray and Carl Sagan welcomed Arthur C. Clarke and Ray Bradbury onstage for a panel: “Mars and the Mind of Man.” Among many cogent remarks, Arthur stated: "whether or not there is life on Mars now, there will be by the end of this century."


Well, well. Unless you count a stray bacterium aboard Sojourner... But we can keep on pushing!


== For your consideration... ==


Hugo Award nominations are now open for Chicon - the World Science Fiction Convention - in September in Chicago, likely to be the best SF con in a generation! I have three possibles, if you care to consider them. For the "Related Works" category, my nonfiction book Vivid Tomorrows: Science Fiction and Hollywood. And a series ripe for consideration in the YA roster: The "Out of Time" (or "Yanked!") series: Only teens can teleport through time and space! Dollops of fun, adventure & optimism for young adults...


... and The Colony High series: aliens kidnap a California high school and live to regret it!  Fun for all ages.


== Sci Fi Flick News! ==


Arthur C. Clarke’s sci-fi novel Rendezvous With Rama will be filmed, with Denis Villeneuve on board to direct. ‘First published in 1973, the novel is regarded as one of the cornerstones of Clarke’s works. Set in the 2130s, the story involves a 31 by 12 mile cylindrical alien starship that enters the Solar System. The story is told from the point of view of a group of human explorers who intercept the ship in an attempt to unlock its mysteries. And yes, I grew up with Arthur's books and helped establish UCSD's Arthur C. Clarke Center for Human Imagination

When it comes to exploring an asteroid that is much more than it seems, I prefer Greg Bear’s Eon. You decide. Still, after excellent adaptations of both Dune and Arrival (based on Ted Chiang's Story of Your Life). I expect nothing but great stuff from Villeneuve.


== SF out of Asia ==


Of course everyone is talking about the Korean film renaissance, after the worldwide success of Squid Game. But neighbors are also at it.


We just watched the Japanese film version (on Netflix) of Robert Heinlein's great classic "The Door Into Summer." Except for a few embellishments which (mostly) improved the story a bit, it is terrifically faithful and well done. Way-fun! (sub-titles)


From China, a charming 20 minute short about a desert village that comes together to create a sci fi flick about a rescue mission to Mars. The Comeback.


And in Asia next year… Rob Sawyer will be one of the Author Guests of Honor at the 2023 World Science Fiction Convention (Worldcon), which will be held August 16-20, 2023, in Chengdu, China. The other two author guests of honor are Sergey Lukianenko from Russia and Cixin Liu from China. Our family much enjoyed being the first foreign SF guests at a major Chengdu SF festival, just before the Yokohama Worldcon, in 2007.


== A  bit of whimsey ==


From the finale of The Expanse: The troopers listed in the drop pods are a variety of sci fi heroes! Like … Rico, J, … Juan "Johnny" Rico from Starship Troopers, Starr, L, that’s Lucky Starr for Asimov’s YA novels, and D. Bowman of 2001. And Ripley and Hicks and Vasquez & Hudson from Aliens... Duncan Idaho from DUNE, Adm. Akbar from Star Wars, Deckard from Bladerunner, Riker from Star Trek, Alex Rogan from Last Starfighter, Neary from Close Encounters, O’Neil from Stargate, Quaid from Total Recall, and Sarah Conner from Terminator. Commander Shepard from Mass Effect, Nesmith from Galaxy Quest, Kara Thrace from Battlestar Galactica.  Bobbie Draper from Expanse and Louise Banks from Arrival and E. Buck from Halo. And Kevin Flynn from TRON and Joseph Cooper from Interstellar. ...Ashamed to say that a few others only sound familiar. But these are pure nerds! And The Expanse was terrific.


And one of you chimed in: “And just to confuse all us fans, R Levine, H Ochiai and K Garrity are all names of karate instructors who've taught Expanse show runner Naren Shankar.”


Alas I’m still chopped liver. sigh.


== Looking back, to look ahead… ==


Are you a fan of Gregory Benford's epic and magnificent “Galactic Center” novels? The series took a quarter century to complete, and Benford traces his own research into the strange structures there. For the first time, all the depth surrounding the series is collected in one volume. The Galactic Center Companion.


And here's my own such guide  - 'Contacting Aliens: A Guide to The Uplift Universe "Of course you recall the nursery rhyme each Earthchild learns, to help remember the Orders of Life — OHow MReality Tricks MEasily — a mnemonic that's philosophically useful as well as handy." — "the 7 known orders of life in the Uplift universe." Can you use the mnemonic to name them all?


Alas now out of print. (Looking for a legacy publisher.)


SFWA's Heritage Author Republication Project (HARP) helps “heritage” authors republish their currently out-of-print backlist titles. The Independent Authors Committee's primary aim for HARP is to help older or disabled authors get their backlist titles back into print, especially books that have never been available electronically and have been out-of-print at least 15 years.


Do you have a favorite long-neglected author of SF? I'm thinking Zenna Henderson, John Boyd, C.L. Moore, Leigh Brackett, Richard C. Meredith, Lisa Goldstein, Hal Clement, James Blish, Roberta MacAvoy, R.A. Lafferty, Meghan Lindholm, Cordwainer Smith, J.D. Bernal, Pat Murphy.


Some greats I simply refuse to believe are out of print! Fritz Leiber and L. Sprague deCamp. Charles Sheffield! But James P. Hogan's 70s and 80s novels are impossible to find. Also Piers Anthony. You’ve likely heard of them, at least, but D.G. Compton is recipient of this year's Cordwainer Smith Rediscovery Award. I assume it isn’t time yet to ‘rediscover” true greats like Fred Pohl or C M Kornbluth or Poul Anderson or Robert Sheckley! Frederick Brown’s epic short stories and those of Eric Frank Russell. Zelazny or Farmer.


Facebook followers also chimed in with Alfred Coppell. John Boyd. Jerry Sohl. Richard Wilson. Clifford D. Simak. Alan E. Nourse. Raymond F. Jones. H. Beam Piper and Keith Laumer will always be beloved of the Baen crowd. But Mack Reynolds? Christopher Anvil?Jack Williamson? And  James Schmitz gave us out first taste of a spunky young heroine in popular sci fi, other than Isaac’s Bayta and Arkady Darrell… the indomitable Telzy Amberdon. (Guys in may age clade fell in love.)


Panshin, Pangborn, Boucher and Russell… Tom Reamy.  Yeah, Van Vogt… though his obsession with portraying uber-lordly demigod supermen above all mortal law grew as tiresome then as it is now with the relentlessly anti-democracy works of O.S. Card.


As a treat, here's a treasury of book synopses of ancient science fiction.


And finally... It seemed like cutting edge sci tech at the time. Dwight Eisenhower – later president – led a cross country truck expedition in 1919 that was epic and showed how crude American infrastructure was. Yet how important.

Strange visitors from beyond...

Oumuamua surprises! The first confirmed and clearly observed visitor from interstellar space has everyone agog. 

Instruments like ESO's Very Large Telescope in Chile show that this unique object - traveling through space for millions of years - appears to be a dark, reddish, highly-elongated rocky or high-metal content object. It varies dramatically in brightness by a factor of ten as it spins on its axis every 7.3 hours. About ten times as long as it is wide, Oumuamua exhibits a complex, convoluted shape... So let me guide you through some aspects of this new scientific wonder.

1) Breakthrough Listen used the Green Bank Telescope in West Virginia to aim SETI instruments at Oumuamua, the interstellar asteroid visitor that - (sorry) shows every sign of being just a rock.  And so, despite its weird - even spaceship-like elongated (cigar-ish) profile - is probably not a giant space-probe, like Arthur C. Clarke (who turned 100 December 17) depicted in Rendezvous With Rama. Or Greg Bear’s even more spectacular Thistledown, from his novel Eon.

Still, I have to wonder… have the SETI guys aimed their scopes also at the direction Oumuamua came from? And where (after a hyperbolic swing past our sun) it’s now going? Might our sun have been a swing-by course correction?

2) Note that this won’t be the last! Our instrumentalities have improved so much that we should be spotting more such interstellar visitors from now on, perhaps yearly!  And yes, you are a member of a great, scientific civilization that does stuff like this!

3) At first, astronomers were shocked to see no signs of a comet-like tail from outgassing, as Oumuamua swung past the sun. Theory suggests that the vast majority of small objects flung from planetary systems should be icy.

But the latest findings suggest water might be trapped under a thick, carbon-rich coating on its surface. The way that 'Oumuamua reflects sunlight and found it similar to icy objects from our own Solar System that are covered with a dry crust. Perhaps carbon rich molecules fused by long exposure to interstellar ultraviolet.

Saving ego for last, let me point out that this model - icy small bodies accumulating layers of insulating dust that choke off outgassing over time, happens to be - in the words of a Monty Python character - “mine.”

My own doctoral work at UCSD, way back in 1981, first laid down the theory and simulations of accumulated dust layers or mantles on comets and other bodies, eventually putting them to 'sleep.'

My scientific work has been sparse, as I pursued a wide variety of careers. But a few of my hits might merit remembering.

== More space news ==

My friend William Schopf of UCLA found what he claimed to be the oldest known example of life on Earth, dated back 3.5 billion yearsSome doubted the objects, were found in 1982 at the Apex Chert, a rock formation in Western Australia, were actually bacteria and microbes. Since then, technology has improved. Schopf and his colleague were able to connect specific carbon-isotope ratios to specific fossil shapes—essentially, enabling them to identify a handful of different ancient living beings. After analyzing the microfossils individually, they identified five species, concluding that two were photosynthesizers, two were methane-consuming organisms, and one produced methane. Wow.

Robert Lawrence Kuhn, host of the TV series “Closer To Truth” gets to ask deep questions of some pretty deep minds. I was privileged to be interviewed for: How should we approach the question of 'are we alone?' "David Brin walks through the logic, along with Jill Tarter, Frank Drake, Francisco Ayala, Ray Kurzweil, Nick Bostrum and others. "

The Planetary Society (I'm on the Advisory Board) is running a contest for Haikus About Space! Here's one - translated from the original dolphin-Trinary:

Oceans everywhere!
Ice roof sheltered, life…
…may fill the cosmos.

A newly discovered pair of massive black holes, orbiting each other very closely in just 80 or so days, has been discovered in the neighboring Andromeda galaxy. Preliminary estimates suggest the pair will collide and merge into one black hole “in as little as 350 years or as much as 360,000 years.” When that happens, the show (especially in gravitational radiation) should be very impressive.   (Hm, well, on more careful reading…  we’re seeing them through Andromeda. They may be 2.6 billion light-years behind (1000 times farther away than the Andromeda Galaxy! Still a great show... but somewhat less dazzling.)

A “zombie” star that appears to have gone supernova… and survived.  Perhaps even several times. Really weird.

A new planet in the neighborhood! In 71,000 years, it will become our closest neighbor, and Ross 128 will be the closest temperate planet.

Meanwhile… preliminary evidence for a second planet orbiting Proxima Centauri. I’m a little doubtful.

In 1975, the USSR actually fired a cannon from an orbiting space station. Forty years later, we finally get a good look at this gun

Cosmic-ray muon radiography allows us to visualize the interiors of large, stony objects. Researchers report using it to study the known and potentially unknown voids in the Great Pyramid in a non-invasive way. They report the discovery of a large void (with a cross section similar to the Grand Gallery and a length of 30 m minimum) above the Grand Gallery, which constitutes the first major inner structure found in the Great Pyramid since the 19th century. At NASA NIAC we funded a study to use this method to map the interiors of asteroids. Wow. 

The first and only cat sent into space – Felicette – was sent up by France in 1963. 

A cool new telescope company has a Kickstarter. Skip the expensive and complex secondary optics and use the prime focus to do images digitally.  Alas,  in fact, their imitation of Newtonian optics for viewing is silly. Skip to a VR goggles method. Contact me, I know exactly how to do it and who can implement!

Another player!  Spaceflight startup Vector — which specializes in micro-rockets — plans to launch its first orbit-bound vehicles from Virginia in mid-2018.  The Vector-R is a four-story-high vehicle that can loft satellites weighing up to 145 pounds into lower Earth orbit. The other vehicle is the Vector-H, which is larger, and capable of carrying 350 pounds to LEO.  They hope for hundreds of launches per year.

Interesting developments in space nuclear power: “NASA is developing reactors for spacecraft propulsion and for a planetary power source, with the goal of having both available for a crewed mission to Mars sometime in the 2030s. But although the agency is advancing a reactor technology that uses low-enriched uranium (LEU), containing less than 20% of 235U for propulsion, its planetary power source, known as Kilopower, utilizes weapons-grade uranium enriched to 90% or more 235U.

“Nonproliferation advocacy organizations have objected to the use of highly enriched uranium (HEU, material containing 20% or more 235U); they say an LEU design, although it would require more time to develop, would be feasible and consistent with US policy.”

Solar energy’s attractiveness is reduced on the Red Planet  because the solar flux reaching Mars is much less than Earth’s and varies greatly depending on the season and geographic position. In addition, Martian dust storms can last for months. Although solar flux on the Moon is comparable to that received on Earth, nonpolar missions would experience a long lunar night period of half a month, which would require massive energy storage.


There is also testing of a nuclear rocket.
