1990 collection of SF stories and speculation about solar sails.
Now here's a thing that doesn't happen much any more, at least in
my life: a fundraising anthology. This book was published to benefit
the World Space Foundation in its attempt to fly a demonstration
light-sail craft.
Introduction: Sailing the Void, Isaac Asimov, introduces the
basics (the difference between photon and charged-particle "winds")
and then gets out of the way.
The Wind From the Sun, Arthur C. Clarke, sits better here than in
that other collection; aimed at the reader who doesn't already know
this stuff, its explanations feel as though they're a bit closer to
the mark.
To Sail Beyond the Sun (A Luminous Collage), Ray Bradbury and
Jonathan V. Post, is to my mind over-long, but I rarely get on with
SF poetry anyway.
The Canvas of the Night, K. Eric Drexler, is wild speculation
about what could be done with lightsails, with a big dose of
libertarian frontierism.
Project Apollo with its first "Moonwalk" was a triumph so great that
it seemed to be what "the space program" was all about, yet the
triumph was not followed up. The voyage of Columbus opened a
frontier by sailing to new lands in a reusable ship. Apollo
virtually closed a frontier by surveying a wasteland in a machine
built at great expense and then thrown away.
…and do you know why, Eric? Because the USSR had lost the race to the
moon, and was far enough behind that it didn't think it could
plausibly beat the USA to the next target, that obviously being a
manned landing on Mars. And the instant the pressure was off, the USA
stopped spending all that money on the glamour stuff.
Ice Pilot, David Brin, is a puzzle-story dressed up as a senatorial
inquiry. Given the obviousness of the solution, one wonders why the
perpetrator was brought back to Earth rather than just asked why he'd
done an apparently foolish thing. But this is one of three original
stories here.
A Solar Privateer, Jonathan Eberhart, is old-fashioned AABB rhyme
with a rhythm to it, but most importantly is just four stanzas long.
It's rather fun.
Sunjammer, Poul Anderson, still works here. In case you've got here
by search rather than by serial reading: it has an explosive cargo and
a solar flare warning, and heroic engineering to deal with the
problem… but, while the characterisation is light, it is at least
present, and one gets some idea that at least these people might come
off duty and get drunk rather than simply being put back in their box
until the next game.
A Rebel Technology Comes Alive, Chauncey Uphoff and Jonathan V.
Post, starts from a basis of "spaceships ought to be cheap so that we
can go out pioneering", and goes on to the proposal for a light-sail
race in 1992 (including forecasting some drawbacks should it go wrong
or fizzle).
Argosies of Magic Sails—Excerpts from "Locksley Hall", Alfred,
Lord Tennyson, is just that. Not sure there's much point to it.
Ion Propulsion: The Solar Sail's Competition for Access to the Solar
System, Bryan Palaszewski, feels like a grudging invitation by the
editors; Palaszewski is clearly more interested in ion thrusters, but
has to make nice about solar sails to be included here.
The Grand Tour, Charles Sheffield, is the main reason I re-read this
collection, because it has a beautiful conceit: a race in cislunar
space with human-powered spacecraft, operating ion drives powered by
Wimshurst generators spun up by human riders. I'm not particularly
convinced by some of the specifics of the technology, but it's fun.
(It's also nothing to do with solar sails.)
Lightsail, Scott E. Green, is more poetry that does nothing for me.
Rescue at L-5, Kevin J. Anderson and Doug Beason, has the orbital
stations above a post-nuclear-war Earth trying to survive… but one of
them has utterly implausible biotech, "sail-creatures" developed for
no obvious purpose, but when exposed to vacuum they conveniently turn
into one-crew lightsail craft. Er, OK. Of the three original stories
in this book, this is the only one to have been republished… in a 2011
ebook of three Anderson and Beason collaborations.
Lightsails to the Stars, Robert L. Forward and Joel Davis, proposes
laser-launched interstellar probes. This may have been where I first
heard about Starwisp and its variants, in particular the
annular-sail braking proposal.
The Fourth Profession, Larry Niven, is the concomitant story: on the
one hand it's the story of a bartender who's taken alien training
pills that work by implanting memories, but on the other it's an
exploration of the technicalities of running an interstellar trading
ship with lightsails (key point: no repeat business). There are the
usual sexist assumptions but much of this one works well, except the
bit where the aliens apparently don't know what their own pills can
do.
Goodnight, Children, Joe Clifford Faust, is entirely unlike anything
else I've read by him; the people are actually pleasant. But this is
mostly an updating of Father Christmas for children on Mars, which,
fair enough. (The last of the original stories for this anthology.)
Solar Sails in an Interplanetary Economy, Robert L. Staehle and
Louis Friedman, looks again at things that could be done (while never
actually mentioning amounts of money), with an obviously wedged-in
section on environmental protection to get the Charles A. Lindbergh
Fund money, and calls for more donations.
Things are definitely looking up. Even without the Columbus Regatta
(though we hope it flies) and operating on a shoestring, we believe
we should be able to fly a test sail soon enough that every person
who bought this book will be able to point up into the night sky and
say, "I helped make that happen."
So what happened? Clearly the WSF didn't get to fly their sail and the
Quincentennial Race never took place; presumably they didn't get
enough money. It does occur to me that much of the private space
launch capacity was relying on military contracts that faded away with
the collapse of the USSR, and rather than open their launchers to
cheaper payloads they just quietly went bust. But while the WSF still
technically exists today, it
appears to be under completely different management ("Dr. Richard
Shope has over 45 years of experience as a writer, mime artist,
educator and entrepreneur"), and is now about "championing science
creativity" in young people. Neither Staehle nor the WSF even has a
Wikipedia page.
But there have been, by my reckoning, just three launches of
spacecraft that have actually got far enough to deploy a lightsail and
be propelled by it, two in 2010 and one in 2019. It's a neat idea, but
in order to make it work we really need more reliable (and cheaper)
ground-to-orbit systems first.
For actual stories, the other anthology is rather better. I also
find it mildly interesting that, among all the people Brin knew in the
SF community, only two quite minor names were prepared to donate
original stories. (I'm assuming they were asked to put any royalties
to the fundraising cause.)
