Konstantin Tsiolkovsky on a Soviet Stamp
Born in 1857, Konstantin Tsiolkovsky grew up in a remote province of Tsarist Russia with his 17 brothers and sisters. His father, Edward Ciołkowskia, was a Polish orthodox priest who had been deported deep into the heart of Russia as a result of his political activities. Edward Russianized his name and married an educated Tartar woman: the two then proceeded to have many children (of whom Konstantin was fifth). When he was 9 years old Konstantin caught scarlet fever and barely survived. Once he finally recovered, he was deaf or very nearly so. Because of his hearing problem he was denied admittance to elementary school and he quickly fell behind his peers. His mother died when he was 13 and his family’s poverty prevented him from moving forward in the world.

This is a very grim and Russian story so far but here is where it becomes extraordinary. Isolated and alone, Konstantin made his way to Moscow. He was teaching himself at the Chertkovskaya Library where a very strange and brilliant man named Nikolai Fyodorovich Fyodorov was an employee. Fyodorov was a transhumanist philosopher and a futurist who believed that humankind’s path forward leads ultimately to technological transcendence and divinity. He felt that scientific progress would eventually lead to physical immortality and then ultimately to the resurrection of all people who have ever died (Fyodorov liked to think “outside of the box”). With the tutelage and mentorship of Fyodorov, Tsiolkovsky taught himself math. He took an active interest in Fyodorov’s scientific philosophy and even began to wonder what could be done with all of the immense number of dead humans if and when they returned. The thought led Konstantin Tsiolkovsky to think about outer space and the subject came to dominate the rest of his life.
Inspired by Fyodorov’s wild ideas and by the science fiction of Jules Verne, Tsiolkovsky began to invent the science necessary to carry humans up gravity’s well and beyond this world. The Encyclopedia of Science summarizes his work as follows:
Tsiolkovsky produced some of the earliest scientific literature on spaceflight, including the classic work Exploration of Space by Means of Reactive Apparatus (1896). In 1898 he derived the basic formula that determines how rockets perform – the rocket equation. This formula was first published in 1903, a few months before the Wright brothers’ historic manned flight. It appeared, together with many other of Tsilokovsky’s seminal ideas on spaceflight, in an article called “Investigating Space with Rocket Devices,” in the Russian journal Nauchnoye Obozreniye (Science Review). Unfortunately, the same issue also ran a political revolutionary piece that led to its confiscation by the Tsarist authorities. Since none of Tsiolkovsky’s subsequent writings were widely circulated at the time (he paid for their publication himself out of his meager teacher’s wage), it was many years before news of his work spread to the West.
No one understood Tsiolkovsky’s work at the time he wrote them. Today the basic concepts behind space travel—such as multistage rockets, orbital velocity, and compressed liquid fuels–are widely understood [Ed. not according to the comments of any given article about space exploration on CNN] but at the dawn of the twentieth century they were wildly fantastic and incomprehensible to international scientists much less to Tsarist Russians. Tsiolkovsky did not stop at elementary proposals of space travel and the fundamental underpinnings of rocketry. He also came up with sophisticated ideas such as using graphite rudders for rocket telemetry, cooling combustion nozzles with cryogenic propellants, and pumping fuel from storage tanks into the rocket’s combustion chamber.
Tsiolkovsky's Conception of a Spaceship
His neighbors regarded him as an eccentric outsider—a deaf schoolteacher mumbling gibberish—but Tsiolkovsky kept on coming up with brilliant ideas, some of which are still ahead of their time. In 1895 he was inspired by the Eiffel Tower to propose the creation of a 35,790 kilometer tall tower surmounted by “a celestial castle” from which objects could be launched directly into space: it was the first conception of a space elevator. By the twenties, as the scientific minds of the new Soviet Union began to realize how innovative Tsiolkovsky’s ideas were, he was contemplating sustainable space habitats and galactic colonization.
Today Konstantin Tsiolkovsky is considered the father of theoretical astronautics—or more simply the father of spaceflight. Sputnik was launched on his one hundredth birthday. Soviet propagandists built many statues and monuments to Tsiolkovsky but the greatest tribute to his legacy (apart of course from humankind’s space programs–which grew from his ideas) has been seen by only a few humans. Tsiolkovsky crater, the most prominent feature on the dark side of the moon is named in his honor.

Goodbye old friend...
The space shuttle program ended this morning when the Atlantis lander touched down at 5:57 AM Eastern Standard Time at the Cape Canaveral spaceport. The national and international media has elegiacally noted the end of the 30 year program, most commonly with articles which sound a dirge-like note concerning the final end of the manned space program (with undertones of America’s decline as a spacefaring, scientific, and military power as well). I am glad those articles are out there because I feel that our inability to ensure adequate funding for basic blue sky research has put the nation’s economic future in jeopardy. Since the dawn of the Industrial Revolution, national greatness has come not from abundant natural resources or a large hard-working population (although the United States has both of those things) but from innovation after innovation. To quote Representative Frank Wolf, a member of the NASA appropriations committee,“If we cut NASA, if we cut cancer research, we’re eating our seed corn.”
We are all the turkey...
However, I am concerned that the story is becoming a self-fulfilling prophecy of defeat and it shouldn’t be. Despite its ever shrinking budget, NASA is actually doing a great deal in space right now as, to a lesser degree, are the world’s other space programs. Five days ago NASA the spacecraft Dawn went into orbit around the protoplanet Vesta, the second largest object in the asteroid belt. Next July Dawn will power up its ion thrusters and fly to the dwarf planet Ceres, an enigmatic pseudo-planet which seems to harbor secrets of the solar system’s beginning under its oceans. Dawn is only one of ten planetary missions currently in orbit (or, indeed onworld) across the rest of the solar system. These are MESSENGER, Venus Express, Chang’E 2, Lunar Reconnaissance Orbiter, Mars Odyssey, Mars Express, Mars Reconnaissance Orbiter, the Mars rover Opportunity, Dawn, and Cassini. Additionally the following eight spacecraft are currently in flight: New Horizons is headed for the dwarf planet Pluto, Rosetta is currently flying to the comet Churymov-Gerasimenko, Japan’s Akatsuki and IKAROS are both in solar orbit, the spacecrafts Deep Impact and ICE, are awaiting further instructions, and finally Voyager 1 and 2 are still out there exploring the distant edge of the solar system. I picked out the projects involving NASA in green (I have already written about the Japanese solar sail Ikaros and our Mercury mission so check out my hyperlinks). These are just the far traveling missions–there are also dozens of near-Earth spacecraft studying the sun, the stars, deep space, and, most of all, the earth.

The shuttle program is not quite as dead as it seems, the Air Force still has two small robot space shuttles and DARPA (the Defense Advanced Research Projects Agency which spawned all manner of world changing technology) is working on next generation spaceplanes. A single-stage-to-orbit space plane (which takes off and lands like a normal plane) is still far off, but aerospace engineers seem confident they could build a two-stage-to-orbit crewed space plane around scramjet technology.

I’m going to miss the shuttles—the white behemoths were major features of my childhood. Back in the early eighties they seemed to hold out all sorts of promises for a glorious future in space. But childhood comes to an end and the shuttles really never lived up to expectations. Now as we Americans sit grounded (unless we want to pay the Russians 50+ million dollars for a seat on one of their old Soyuz spacecrafts), it is time to think about what we want. Maybe humankind will catch a break and see breakthroughs in molecular or nuclear engineering which leave us with a new range of materials and energy possibilities (despite its long quiet phase, I still have high hopes for the National Ignition Facility). I have always harbored fantasies of a nuclear power plant on the moon with an attached rail gun for space launches. I also like the idea of a space elevator, or a twirling toroid space habitat with false gravity. The always deferred Mars mission is exciting too (although we have talked about it so long that some of its glitter has come off). But I’m open to other ideas. We all should be. We need to talk about it and then we need to decide on some ideas and fund them quickly. Seeds need to be planted to grow.
If we call it an orbital railgun, people will be upset. How about "orbital railfriend"?
