This was the first Mars lander designed after the bombshell from Mariner 4 that astronomers had drastically over-estimated how dense the Martian atmosphere was. They had figured it was a useful 85 hectopascals hPain reality it was an almost worthless 6 hPa just slightly better than a vacuum.

Going off of a very rough historical comparison to WW1 and earlier naval organizations try: The logistical support ships, cargo, colliers, oilers, etc. Some support vessels were never organized into units at all. Assuming a techlevel more advanced than nearfuture i.

If you are able to intercept and kill another warship across a star system, you are also capable of reducing to radioactive rubble an entire planetary civilization with little effort. From Tobias Pfennings The brain trust that I copy from research for spacecraft combat material have developed their own private jargon.

As a public service I present a small glossary so you decipher what they are talking about. Basically a mobile control center for combat drones. Sort of like the brain center inside a huge swarm of deadly metal space-going hornets with nuclear stingers.

The idea is that the control ship and its human crew stands off at a hopefully safe distance from the battle, and sending in hordes of expendable drones to savage the enemy ships. Please note that the control ship probably will NOT carry and service the drones, since the control ship will have to be nimble enough beat a hasty retreat if the battle goes terribly wrong.

The drones will be carried by separate parasite-carrier spacecraft. The control ship might contain the only live human beings in the entire swarm. Since the acceleration of the projectile increases with the length of the weapon barrel, these tend to be in spinal mounts.

Requires large amounts of electricity advantage: They are basically huge numbers of dime-a-dozen chemical-rocket-powered kinetic-energy-weapons. It is such a good defense it could render torch missiles to be totally worthless.

Generally this is a preposterous waste of your combat dollar, unless there are special circumstances.

Right off the bat the Lancer spacecraft will need at least four times the delta-V of an equivalent missile, since unlike the missile the Lancer is not on a suicide mission.

A missile just has to do one burn to the target. The lancer has to burn for the target, do a counter-burn to stop, do a burn for home, and do a counter-burn to stop at home. Science fiction authors and game designers find this to result in scenarios that are drearily boring, so they often go out of their way to try to figure out extenuating circumstances to ensure military combat in their novels is non-Lanchesterian.

Occasionally the term is used for an impressively armed combat spacecraft suitable for political use in gunboat diplomacy. This poor term is used in a variety of conflicting ways in this website. Though all of definitions refer to something that is self-propelled, as opposed to railgun shells and other gun-launched kinetic energy weapons.

Since it is self-propelled, it does not require large amounts of electricity disadvantage: But each missile is an expensive precision crafted device containing its own fuel advantage: In standard military parlance, a "missile" is guided while a "rocket" is unguided.

Rick Robinson suggests that a "torpedo" is a missile with acceleration less than a spacecraft while a "missile" is a missile with acceleration greater than a spacecraft the same way a wet-navy battleship can dodge a sea-going torpedo but not a guided missile.

Technically a mothership that carries smaller vehicles internally is a parasite carrier Sometimes spelled "mother ship" or "mother-ship". The classic example is the Battlestar Galactica, a space-going fighter-aircraft carrier.

But science fiction has examples of huge battleships containing a few destroyer-sized ships. The classic example is parasite fighters housed inside a fighter-carrier, e.Find out more about our scholarship and eligibility requirements, fill out our form and send us your essay. The easiest propellant to manufacture is liquid carbon dioxide.

It can be produced from the Martian atmosphere using just high pressure ( kPa) with no cryogenic cooling needed (a 30 horsepower pump will do, requiring 25 kW, or 80 kilowatt hours per metric ton).

These are some spacecraft designs that are based on reality. So they appear quite outlandish and undramatic looking. In the next page will appear designs that are fictional, but much more breathtaking. Obviously the spacecraft on this page are all NASA style exploration vehicles, they are not very suited for interplanetary combat (well, most of .
