Having joined the Planetary Society this year, I thought I’d want to see some of these planetary folks in person. So I decided to visit the International Symposium on Solar Sailing 2010 (ISSS 2010) on that particular day when the Planetary Society would be there as well.
The trek to New York City College of Technology in Brooklyn seemed quick. I was reading Paul Gilster’s Centauri Dreams to maximize what little time I had, focusing my attention on the book, instead of gazing at the pretty woman seated across the aisle of my subway train ride.
I was late as usual, but was fortunate to see the last part of a lecture that was pretty amazing. I was shocked to see so few people attending the event. (To think that the online ticketing said it was fully booked--which nearly discouraged me from going). But I’m glad I still came to visit the event.
There were kids intently listening to the panel. And no doubt there were folks that were “young at heart” and very enthusiastic about space travel and exploration.
Then there was Bill Nye, the “Science Guy” whom Louis Friedman now introduced as the “Planetary Guy”. Bill Nye moderated the event with gusto, making the event livelier. His enthusiasm is really needed to inspire more people about planetary things.
During the the Q&A portion, I wasn’t picked to ask a question. But as the event ended, I was glad Bill Nye asked the same idea I was meaning to ask, “Will Solar Sailing take us to other Star Systems?” He then handed the mic to Louis who said it is quite a challenge pushing solar sails across interstellar space where the sunlight would become so feeble as the probe gets farther away from the sun. The current idea would be to push it using a highly-focused powerful laser (with information in it, too). Then he said that it would be another 100 to 200 years before we can truly send a solar sail probe to other stars.
Suddenly, with arms flailing--as if trying to swipe away the somewhat discouraging aspect of hearing a “hundred years”--Bill Nye ended the gathering with encouraging remarks about how incredible Solar Sailing truly is.
On my way out, I saw another truly inspirational scene. There were books on display directly in front of the exit doors, and I saw an elderly woman excitedly buying a couple of Gregory Matloff's and Les Johnson’s books (one was “Living off the Land in Space”). She was the same woman whom I overheard a bit earlier speaking to one of the panelists, "Thank you so much. This event is wonderful! There should be more publicity to these kinds of stuff!"
As I headed home, I continued to read Centauri Dreams ardently that I missed my stop. At the back of my mind I was thinking about that old lady. Her enthusiasm is fresh and vigorous. I am inspired. It’s never too late, nor anyone too old, to be enthusiastic about anything at all, even about dreams that will outlive us.
To me, that is the kind of human spirit that will take us to the stars.

On IKAROS and Interplanetary/Interstellar Kites
I love kites. I have three stunt kites among others which I sometimes fly on summer weekends at the park near Liberty Science Center (overlooking New York City) where the constant breeze is best for kite-flying around the area. To this day, I am still amazed how the wind translates to flight.
As a child growing up in the Philippines, I often ran in the streets with a kite I made out of newspapers and "walis tingting". As I pulled on the string (which i stole from my grandmother's sewing kit), I wondered how high and how far my kites could go. I remember myself asking if they could go past the clouds, the blue sky, and out beyond the unknown expanse.
The answer came many years later, but its so much better than it could ever be.
On May 20, 2010, an interplanetary kite has been launched that will fly to another world. The IKAROS will go to Venus and beyond.
The IKAROS (Interplanetary Kite-craft Accelerated by Radiation Of the Sun) is a solar sail mission powered solely by sunlight. A solar sail is pushed by the photons from the Sun. In other words, it uses sunlight to sail.
When a photon is reflected it exerts a small force on the surface reflecting it. The Sun generates a lot of photons, so if you have a large, lightweight, reflective surface, it will be pushed by the force of many photons being reflected off it. It is the reflected photons that creates the "pushing" effect.
The solar sail hitched a ride aboard an H-2A rocket from Japan's Tanegashima Space Center. That rocket carries the main mission of the Japan Aerospace Exploration Agency (JAXA), the Venus Climate Orbiter called Akatsuki.
IKAROS is the first of it's kind to ever be launched and I hope it will work because it's success will pave the way for future solar sail missions that may even extend past our Sun into other stars. Thus, I have whimsically labeled a future acronym for it's successor: Interplanetary Kite ARound Other Stars (IKAROS).
I am very excited about IKAROS so I watched it's launch on a live feed. Perhaps watching its launch was related to the fact that launching my jetstream kite from the ground is also my favorite part.
My kite is initially in a launch position, facing the wind, facing me, and pointing up. I wait for a suitable gust of wind to pass through my back and reach the kite. At the right moment, I pull both strings and step backwards, I can feel the strength of the wind as I watch the kite accelerate upwards. For me, it is the most exhilarating part of flying kites. I advise you to try it.
By the way, did I mention that "Exoplanetology" is actually riding the IKAROS? Yes, a few months back I actually filled up a form at The Planetary Society's website to send a message to be carried along with IKAROS. Unfortunately, it wasn't encoded in the certificate of participation that was provided, but my message was "Interplanetary Now, Exoplanetary Next".
I hope that this short message encourages others in the hope that one day, we will have a probe exploring another solar system, and most importantly--an extrasolar planet!
