Space Wars

  1. It took the team about 200 man-hours to write the first version of Spacewar. Russell wrote Spacewar on a PDP-1, an early DEC (Digital Equipment Corporation) interactive mini computer which used a cathode-ray tube type display and keyboard input.
  2. Spacewars is a turn-based tactical online strategy MMO, where real-time travel meets turn-based combat. The universe is made up of four asymmetrical races, with very different play styles from each other. Players choose a starting race, and a starting ship, with a customized Captain as their avatar.

Space Wars is a competitive, two-player video game released in arcades in 1977 by Cinematronics. Like the 1962 PDP-1 program Spacewar! it is based on, it uses black and white vector graphics for the visuals. The hardware developed for Space Wars became the platform for most of the vector-based arcade games from Cinematronics. A Vectrex port was published in 1982.

Gameplay[edit]

Two players controlled different ships. One button rotated the ship left, another rotated the ship right, one engaged thrust, one fired a shell, and one entered hyperspace (which causes the ship to disappear and reappear elsewhere on the playfield at random).

The game offered a number of gameplay options, including the presence or absence of a star in the middle of the playfield (which exerted a positive or negative gravitational pull), whether the edges of the playfield wrapped around to their opposite sides, and whether shells bounced. The game had three particular features: First, the game could not be played in 'one player' mode; a human opponent was required. Second, the player's ship could take a glancing hit without dying, but would suffer damage; a cloud of loose ship fragments would break off and float away, after which the ship would be visibly damaged on screen and would turn and accelerate more slowly. Third and most memorable was that the duration of play for any contest was solely governed by the amount of money deposited; each quarter bought a minute and a half of play. A dollar bought six minutes, and for a ten dollar roll of quarters two players could play non-stop for an hour.

Development[edit]

Larry Rosenthal was an MIT graduate who was fascinated with the original Spacewar! and developed his own custom hardware and software so that he could play the game. Cinematronics worked with Rosenthal to produce the Space Wars system.

Legacy[edit]

Space Wars formed the basis of the platform used by Cinematronics for their subsequent black-and-white vector games such as Star Castle and Tail Gunner.

The former U.S. Space Command, which is now part of the U.S. Strategic Command as of June 2002, doesn't hide the fact that it wants to establish U.S. supremacy in space. In its Vision for 2020 report, the Space Command points out that military forces have always evolved to protect national interests, both military and economic. The report suggests that space weapons must be developed to protect U.S. satellites, and other space vehicles, as other countries develop the ability to launch spacecraft into space. In 1997, Assistant Secretary of the Air Force for Space, Keith R. Hall, said, 'With regard to space dominance, we have it, we like it and we're going to keep it.'

The Pentagon has said that as space enterprises begin to gain commercial advantage, there will be those who try to take some of the profits by attacking those space enterprises. Here are some of the space weapons currently under development:

  • Chemical Lasers
  • Particle Beams
  • Military Space Planes

There are at least three laser systems being developed for either space-based or ground-based weapons. All three are a type of chemical laser that involves the mixing of chemicals inside the weapon to create a laser beam. While a space-based laser system is still about 20 years from being realized, there are three lasers being considered for it, including hydrogen fluoride (HF), deuterium fluoride (DF) and chemical oxygen iodine (COIL).

In a 1998 report titled Laser Weapons in Space: A Critical Assessment (PDF file), Lt. Col. William H. Possel of the U.S. Air Force compared the workings of the hydrogen fluoride laser system to the way a rocket engine works. Atomic fluorine reacts with molecular hydrogen to produce excited hydrogen fluoride molecules. This reaction creates a wavelength between 2.7 and 2.9 microns. At that wavelength, the hydrogen fluoride laser beam would be soaked up by the Earth's atmosphere, meaning that it is most likely to be used in space-to-space combat as part of the Space-Based Laser program. The Ballistic Missile Defense Organization has already demonstrated a hydrogen fluoride laser with megawatt power in a simulated space environment.

Another laser, similar to the hydrogen fluoride system, is the deuterium fluoride laser system. Instead of using molecular hydrogen, deuterium is used to react with atomic fluoride. Because deuterium atoms have more mass than hydrogen atoms, this laser has a longer wavelength, about 3.5 microns, and can transmit better through the atmosphere. In 1980, TRW demonstrated a deuterium fluoride laser, called the Mid-Infrared Advanced Chemical Laser (MIRACL), that can produce more than one megawatt of power. This type of laser system was used in tests to shoot down a rocket at the White Sands Missile Range in 1996.

The third type of chemical laser that might be used in ballistic missile defense is the chemical oxygen iodine laser (COIL), which made its debut in 1978. In this laser system, a reaction generated between chlorine and hydrogen peroxide excites oxygen atoms, which transfer their energy to iodine atoms. This transfer of energy causes the iodine atoms to become excited, creating a laser with a wavelength of about 1.3 microns, smaller than either of the two previously mentioned lasers. This smaller wavelength means that smaller optics could be used to develop a space-based lasing system. In 1996, TRW tested a COIL laser that produced a beam with hundreds of kilowatts of power that lasted several seconds. Right now, this is the most promising of the spaced-based lasers in development.

One of the problems with space-based lasers is that they would have to be fixed to a moving satellite as they tried to hit another moving object moving at thousands of miles per hour. Imagine trying to shoot a bird from aboard a supersonic jet. The laser and the object it is trying to hit will likely be traveling at different speeds, making it an almost impossible shot. This is why the U.S. Department of Defense is also considering a particle beam weapon, which would be able to fire beams of subatomic particles, at near the speed of light, at a military target. If a beam could be fired at those speeds, it would, for all intents and purposes, freeze the targeted object.

A particle beam weapon would be able to generate power many times more destructive than any laser in development. Such a weapon would essentially be composed of two parts: a power source and an accelerating tunnel. If a functional particle beam weapon could be built, it would use its power source to accelerate electrons, protons or hydrogen atoms through the tunnel, which would focus these charged particles into a beam that would be fired at the target.

The 'bolts' of energy fired from the particle beam weapon would enter into the target's materials, passing the energy onto the atoms that compose the target. This impact would be like a cue ball striking a racked group of billiard balls on a pool table. The rapid increase in the target object's temperature would cause the object to explode in a matter of seconds following impact.

The major obstacle in developing a functional particle beam weapon has been creating a power source that is light enough to put into space, but that can produce millions of electron volts of power and tens of megawatts of beam power. A conventional power station would be able to meet those power demands, but it is far too large to put into orbit. So far, scientists have not been able to develop a suitable lightweight power source that can meet those power demands.

The X-33 space plane may be used for military combat in space.

Space Wars Trump

A third space weapon in development is the military space plane. A joint venture between NASA and the Air Force is trying to develop a space plane labeled the X-33. While President Clinton line item vetoed the Air Force portion of the military space plane in 1998, NASA has continued development of the space plane for non-military reasons. If the Air Force were to rejoin the development of the space plane at a later date, it could use the vehicle to control space both offensively and defensively.

Currently, there are many international agreements that have prohibited the deployment of such weapons into space. One such agreement is the Outer Space Treaty of 1967, which covers outer space, the Moon, and other celestial bodies. The one loop hole in this treaty is that it doesn't say anything about the area just above Earth, where most satellites are in orbit. However, the treaty does prohibit placing nuclear weapons, or other weapons of mass destruction, into Earth's orbit. But the question is, are lasers and particle beams weapons of mass destruction? The treaty further prohibits the construction of military bases and fortifications on any celestial body, including the Moon.

In November, 1999, 138 United Nations members voted to reaffirm the Outer Space Treaty. Only the United States and Israel abstained from the vote. Based on that vote, which upheld the ban on weapons in space, it would seem that space weapons will remain grounded for the time being. So, for now, thoughts of Death Star-like weapons and X-Wing fighters, battling it out thousands of miles into space, will have to be put on hold.
