The Greatest Warrior Cultures From History


Norman_warrior_1
Since the dawn of mankind, the ambit of conflict has always been a constant feature in the intricate tapestry of history. And in such a vast scope of destruction and death, there have been a few civilizations, tribes and factions that have rather ‘thrived’ on warlike conditions. So, without further ado, let us check out the fifteen of the most disciplined, ferocious yet tactically evolved warrior cultures who had nigh perfected the ‘art of war’ or rather the art of dealing with war.
*Note – The list does not only reflects their successes in battles or wars, but it also pertains to how they perceived the scope of war or conflict.
Assyrian –
Assyrian_Warrior
During their zenith period from 10th century BC to 7th century BC, the Assyrians controlled a vast territory that extended from the borders of Egypt to the eastern highlands of Iran. Many historians perceive Assyria to be among the first ‘superpowers’ of the Ancient World. And quite paradoxically, the rise of Assyrian militarism and imperialism mirrored their land’s initial vulnerability, as it laid inside the rough triangle between the cities of Nineveh, Ashur and Ardabil (all in northern Mesopotamia).
In essence, the Assyrian rulers had to maintain an effective military out of necessity that could launch offensive campaigns against enemies surrounding their precariously positioned kingdom. The grand result was a standing army with ruthless discipline, order, uniformity and a penchant for using advanced siege weaponry like gargantuan mobile towers and boisterous siege engines.
Scythian –
Scythian_warrior
One of the Iranian equestrian tribes that dominated the Eurasian steppes from 7th century BC till 3rd century BC (but continued well into the 4th century AD), the Scythians epitomized the rise of the semi-nomadic people that excelled both in unorthodox warfare and horsemanship. In fact, many authors believe that the Scythians had a lasting influence on the their neighbors so much so that even after 1,000 years of their passing, the land in which they dwelt and dominated (present-day northern areas of Black Sea) was known as Greater Scythia.
As for their renowned warlike nature, the Scythian horde (in its nascent stage) boldly managed to invade Assyria and even reached the borders of Egypt during 650 BC. After exacting tributes from the Pharaoh, they returned to plunder Assyrian and might have even toppled the Median (upper Iran) aristocracy. A biblical prophet sums up the baleful effect of the ferocious ‘horse lords’ –
They are always courageous, and their quivers are like open grave. They will eat your harvest and bread, they will eat your sons and daughters, they will eat your sheep and oxen, they will eat your grapes and figs.
Spartan –
Spartan_hoplite
Just to make it clear, there are certainly skewed views of both Spartans and Persians (who were arguably more advanced in culture) in popular media, no thanks to biased Hollywood representations (read this post). But from the perspective of pure history (and not fantasy), Spartans or Lakedaimonians maintained the only full-time army in all of Greece. To that end, the institutions of the state and even Sparta’s education systems were organized to create soldiers first, statesmen later.
In fact, a Spartan boy started his military training at the age of six, when he was taken from his home to live in barracks. By the age of twelve, the boy was already treated as a youth who was expected to show martial skills and survive with bare minimum diet (he was also expected to steal to keep his hunger pangs away – and on being caught, he was severely punished for getting caught, not stealing!). On turning eighteen, he was finally considered as an adult and a soldier of the Spartan society, but was still prohibited from entering a marketplace to talk with his fellow adults till the age of 30. In consideration of all these strict rules, Plutarch once observed that the only rest a Spartan got from training for war was during the actual war.
Roman –
Roman_army_1
To write about the Romans in a single paragraph is indeed a fool’s errand. But if there was any empire that had tailored its military strength to nigh perfection – it was the Romans. We use the term ‘tailored’ because a Roman legion was not about individual capacity, courage or ferocity (like their nemesis, the Gauls); rather it was more about disciplined teamwork, formations, and their remarkable executions on the battlefield that resulted in a combined strength of arms. The evolving political structure of the Republic (and then Empire) also helped the Roman army in its long list of conquests stretching from Spain to Syria, and from North Africa to Britain.
However, the greatest strength of Rome was arguably not in its arms, but rather its unflinching capacity to bounce back from disastrous circumstances. A good example would be the Battle of Cannae, when Rome lost 48,200 soldiers in a single day (according to Livy, it was 80 percent of the army). The burgeoning republic still managed to survive, to ultimately defeat Hannibal at the very gates of Carthage.
 Boii
Boii
Thought to be a Gallic tribe from the later Iron Age, the Boii were mainly centered around Bohemia (present-day Czech Republic), Pannonia (present-day Hungary) and Cisalpine Gaul (present-day Northern Italy). The warlike people were famous historically because of the momentous Gallic invasion of Italy in 390 BC, when they took over the Etruscan city of Felsina, and turned it into their new capital Bononia (now known as Bologna).
And, even beyond historical instances, it is the name ‘Boii‘ that holds special significance in relation to their warrior culture. To that end, some linguists (like Julius Pokorny) have attested that Boii itself pertains to ‘warrior’, derived from Indo-European *bhei(ə)- “hit”. In any case, the Boii showed their renowned martial capacity when they aided the great Hannibal himself in defeating the Romans in 216 BC.
Lusitanian –
Lusitanian_warrior_1
We included the Lusitanians in this list mainly because of their special tactics used during battles, which entailed the very concept of ancient guerrilla warfare. Roughly occupying most of modern Portugal (south of Douro river) along with the central provinces of Spain, the Lusitani were a part of the Celt-Iberian group. And quite oddly, unlike their Gallic neighbors or even kingdoms from across the Mediterranean Sea, the Lusitanian tribes were never warlike in the proper sense of the word. However, they did show their military acumen and even might, when provoked – as was the case during the Hispanic Wars and the campaigns of Lusitanian hero Viriatus against Rome. It is estimated that the Romans and their Italic allies lost around an astronomical 200,000 soldiers during the 20-year period of war between 153-133 BC!
And even beyond figures, it was the unique essence of unconventional warfare that really made the ancient Spaniards stand out from their contemporaries. As Polybius had noted – the Hispanic Wars were different because of their unpredictability, with Lusitanians and other Celt-Iberians adopting the tactic of ‘consursare‘ (which is sometimes described as ‘lack of tactics’) that involved sudden advancements and confusing retreats in the heat of the battle. Moreover, the Lusitanian young men were known to be the ‘desperados’ of the ancient times because of their penchant for gathering riches through robberies. Their warrior society also followed a cult of trim physique, with body slimness being rather accentuated by wearing of wide yet tight belts around the waist!
Huns –
Huns_1
Circa 636 AD, Bishop Isidore of Seville called the Huns – the “scourges of God’s fury”. The dramatic overtone of the sentence does symbolically underline the terror and ruthless destruction brought on by this Asiatic nomadic horde upon the very heartland of Europe. However, the oft used image of the ‘barbarous’ Huns rampaging through civilized nations is actually a misleading notion – since the Huns themselves were a sort of a ‘super-entity’ of variant tribes who had been neighbors to sophisticated agrarian societies for centuries. As a result, the Hunnic people adopted many of the foreign customs, including even that of a Roman bathhouse, which was supposedly used inside Attila’s large village-camp.
Many historians have pointed out that the idea of limitless ‘hordes’ of Huns might also be fallacious, since the Huns themselves comprised of only a few ten-thousand horsemen. This actually alludes to the military effectiveness and the ruthlessness of the nomadic force – as they were able to instill the foreboding sense of fear in their enemies, in spite of their relatively small numbers. The brilliantly rapid tactics involving swift horses and swifter arrows also helped Attila and his ‘hordes’ in overcoming their cumbersome European foes.
Frank –
Frankish_warrior
The Franks are thought to be a confederation of Germanic tribes who came into historical significance in 3rd century AD, during the period of the First Migration Period (or Völkerwanderung in German). In reference to pre-migration Germanic tribes, this is what Roman historian Tacitus had to say in the 1st century AD –
A German is not so easily prevailed on how to plow the land and wait patiently for harvest as to challenge a foe and earn wounds for his reward. He thinks it spiritless to accumulate slowly by the sweat of his brow which can be got quickly by a loss of a little blood.
This pretty much summarizes the ‘urge’ of fighting which was prevalent in most episodes of German inter-tribal conflicts. The Franks however brought out the socio-political side of this potent Germanic military force, and ultimately carved out the Merovingian empire by 5th century AD (which consisted of both modern-day France and Germany). In fact, the name ‘France’ is itself derived from this super-tribe, while the term ‘Frank’ might have been derived from the Germanic word for the weapon of ‘javelin’.
Viking –
Viking
The multitude of impressions that the Vikings had on their opponents and victims can be comprehended to some degree by the various names that these sea-faring invaders from Scandinavia were given. The Irish called them Gaill or ‘strangers’, the Byzantine sources mention them as Varangoi (derived from var – a group of men sworn to each other), and the Muslim sources describe them as al-Madjus or ‘heathen wizards’! But one thing was for certain – the Vikings epitomized the very term ‘warrior culture’.
Using their acumen for building ships, the Vikings were able to raid swiftly along the booty-laden coasts ranging from North Atlantic islands, Russia to Constantinople (present-day Istanbul) and Middle Eastern territories (Viking presence was even found in Baghdad) – an effective stratagem that was nigh alien to then-contemporary factions. However, such expeditious gambits were antithetical to the actual land battles in which these Northerners participated. A good example would be the use of the ‘solid’ shield-wall where massive blocks of men adopted a stationary, defensive stance which was nigh polar opposite in tactical terms to the swift raids by the seas. Such ploys along with the usual bouts of viciousness (like going ‘berserk’) alludes to the versatility of a Viking as an energetic warrior.
Norman –
Norman_warrior_1
Simply put – the Normans continued where the Vikings left. Their name being derived from Latin Nortmanni, the Normans themselves gave their name to the northern province of Normandy in France. And historically, they were actually the descendants of the Vikings who had settled along this strategic coastal area, and had intermixed with the native Merovingian stock. The result was a resourceful people who believed in their indigenous culture of Gens Normannorum – which to some degree fueled their ‘destiny’ to explore and conquer lands across various parts of Europe and even Asia.
This self-identifying sense of ingenuity and adaptability allowed the Normans to basically succeed where the Vikings failed. To that end, the Normans were known for their equal measures of ferocity and cunning, while their thriving culture inculcated military prowess and leadership at the same time. So, it really doesn’t come as a surprise that the Normans (like William the Conqueror) are still counted as the last continental force that successfully invaded Britain. Additionally, they established long-lasting kingdoms in Southern Italy, Sicily and even Antioch (present-day southern Turkey). And, at last but not the least, they were among the early proponents of shock cavalry with couched lances – a factor that gave rise to the knightly class; warriors who were to dominate European battlefields for centuries to come.
Rajput –
Rajput_1
The term Rajput comes from Raj-putra, which in Sanskrit translates to ‘son of king’. Rising in prominence during the later part of 9th century, the Rajputs organized themselves as one of the dominant Hindu warrior classes (or Kshatriyas) around the northern regions of India (especially in Rajasthan, Uttar Pradesh and Delhi). Interestingly, historians have not been able to strictly identify their origins, which is an irony – since most Rajput clans gave importance to their so-called noble lineages. In any case, the defining nature of the Rajputs related to their martial prowess, not their confusing or hyperbolic origins; as historian Pradeep Barua had put it forth –
What makes the Rajputs stand out from the rest of Indian society was not their (probable) foreign origins but their fanatical attempts to assert their Kshatriya status. Over time, other Indian groups followed their example and claimed descent from the (mythological) solar and lunar races, establishing themselves as Rajputs in various parts of western and central India.
Such ‘attempts’ actually reflect the Rajput warrior ethos, courageousness against overwhelming odds and their free-spirited aspirations. In that regard, we also know of the Rajput’s love for his weapon – which was seen as a physical extension of his martial resolve and ardor. This tendency was specially signified by the ritual of Karga Shapnathat amounted to ‘love for the sword’, after which the warrior was given free reign to pursue his passion for honor, revenge and even plunder.
Mongol –
Mongol_warrior_1
Once the rulers of the largest contiguous land empire ever witness in the history of the world, the ruthlessness of the Mongol warrior needs no introduction. But unfortunately in an objective manner, it is this very veneer of ruthlessness that has overshadowed the true Mongol achievement in military history – their veritable mastery of the very art of war. This dramatic statement is backed up by purely statistical terms. The Mongols have won the most number of battles (than any other global faction), they had controlled the largest expanse of land territories ever known to mankind, and is still counted among the very few invasion forces that had successfully conquered Russia during the winter season – a gambit that was taken as an advantage for their own improved mobility along frozen lakes and rivers.
All of these momentous feats pertain to the grand strategies of their leaders followed to the letter by tactical blitzes and military acumen. In essence, the Mongol horde was not just a nomadic ‘horde’ of barbarous horsemen rampaging across lands of sedentary civilizations – rather, it was an imposing war machine in itself, with far-advanced organizational capacity than its opponents, which was equally matched by tenacious ferocity and mobility of the individual Mongol.
Samurai –
Samurai
Japan’s feudal answer to European knights, Indian Rajputs and Arabian Faris; the Samurai served as the military nobility of the far-east nation for over 700 years. But oddly enough, the Samurais didn’t actually start out as higher ranking members of the Japanese society – they rather served the roles of private bodyguards of rich landowning clans before 12th century AD. As a matter of fact, they were instrumental in turning the tides of war for Minamoto Yoritomo in 1192 AD, who toppled the central government to start Japan’s first Shogunate – which in practice was a state ruled by a military commander.
However, the Samurais truly reached the highest echelons within feudal Japan’s rigid social structure during the warring Edo Period from 1603 AD to 1867 AD. Mirroring their newly found social ranking, they were only the men allowed to own and carry swords, while their permanent residences were fixed by their daimyos or feudal lords within castle-towns. Other than swords, the Samurais were also known for their mastery of other weapons like bows and arrows, spears and even guns. But arguably more renowned was their fanatical adherence to the warrior code of Bushido, which evolved after the 16th century with concepts of loyalty, honor, warrior ethics, along with ideas of neo-Confucianism, Shinto and Zen Buddhism.
 Mamluk –
Mamluk_warrior
The military culture of the Mamluks is perhaps the most unique among all the entries here, as the very term ‘mamluk‘ denotes a slave. In essence, the Mamluks were recruited from various ‘fringe’ factions including that of Turks, Kipchaks and Circassians – which was a pretty common Muslim military practice from the time of the Abbasid Caliphate, when the slave soldiers were known as ‘ghulams‘. The last great Ayyubid sultan (Saladin’s dynasty) al Salih expanded the scope of this slave recruitment in a bid to unify his realm through strength, which resulted in an elite corp of Mamluks making their base in Cairo. These slave warriors finally toppled al Salih’s own son, to start the Mamluk Sultanate that successfully drove away the remnant Crusaders, defeated the Mongols and even rivaled the future Ottomans.
Now, the term ‘slave’ can be misleading from our modern perspective. But historically, recruited slaves in most Islamic kingdoms, had a far more honorable status and even higher standard of living than that of ordinary folk. The Mamluks carried this incredible tradition forward with evolved emphasis on rigorous military training, religious piety and even literary education. The result was a highly motivated and heavily armored group of men – who for all-intents-and-purposes belonged to the crème de la crème of the medieval Egyptian society, in spite of them being foreigners in almost all cases.

Amazing Extinct Animals

Baiji River Dolphin


We all love dolphins, but these majestic creatures that lived in China’s Yangtze River for about 20 millions years were declared officially extinct after an expedition to search for them failed. To this day people still search in hopes of spotting one.



 Elephant Bird: extinct circa 17th century

This huge bird was part of the ostrich family and inhabited the island of Madagascar. It's height was approximately 10 ft tall with eggs 15 times larger than an Ostrich, it's said they were delicious which was probably part of it's downfall.



Zanzibar Leopard: extinct 1996

A native to Tanzania, this leopard's demise are due to man's deforestation efforts and hunting. There's a story of local tribesmen says the tiger was "owned by witches", hence the hunting.




 The Dodo: extinct 1681


Living on an island in the Indian Ocean, the Dodo was a bird that didn't fly or swim and it ate only fruit. European settlers wouldn't eat them because they tasted bad and instead brought pigs to island to bred. The pigs ate the Dodos' fruit, and sadly the Dodo eventually starved









Great Auk: largest of all auks (extinct since 1844)
The Great Auk was the only species in the genus Pinguinus, flightless giant auks from the Atlantic, to survive until recent times, but is extinct today. It was also known as garefowl, or penguin. 



Resultado de imagem para Great Auk



Standing about 75 centimetres or 30-34 inches high and weighing around 5 kg, the flightless Great Auk was the largest of the auks. It had white and glossy black feathers. In the past, the Great Auk was found in great numbers on islands off eastern Canada, Greenland, Iceland, Norway, Ireland and Great Britain, but it was eventually hunted to extinction. Remains found in Floridan middens suggest that at least occasionally, birds ventured that far south in winter as recently as in the 14th century. 

Cave Lion: one of the largest lions ever (extinct 2,000 years ago)



The cave lion, also known as the European or Eurasian cave lion, is an extinct subspecies of lion known from fossils and a wide variety of prehistoric art. This subspecies was one of the largest lions. An adult male, which was found in 1985 near Siegsdorf (Germany), had a shoulder height of around 1.2 m and a length of 2.1 m without a tail, which is about the same size as a very big modern lion. This male was even exceeded by other specimens of this subspecies. Therefore this cat may have been around 5-10% bigger than modern lions. It apparently went extinct about 10,000 years ago, during the Würm glaciation, though there are some indications it may have existed as recently as 2,000 years ago, in the Balkans. 


Tyrannosaurus Rex (extinct 65 million years ago)

Resultado de imagem para Tyrannosaurus Rex




Tyrannosaurus rex was one of the largest land carnivores of all time, measuring up to 43.3 feet long, and 16.6 ft tall, with an estimated mass that goes up to 7 tons. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small and they retained only two digits. 

Fossils of T. rex have been found in North American rock formations dating to the last three million years of the Cretaceous Period at the end of the Maastrichtian stage, approximately 68.5 to 65.5 million years ago; it was among the last dinosaurs to exist prior to the Cretaceous-Tertiary extinction event. More than 30 specimens of T. rex have been identified, some of which are nearly complete skeletons. Some researchers have discovered soft tissue as well. The abundance of fossil material has allowed significant research into many aspects of its biology, including life history and biomechanics. 


Quagga: half zebra, half horse (extinct since 1883)

One of Africa's most famous extinct animals, the quagga was a subspecies of the plains zebra, which was once found in great numbers in South Africa's Cape Province and the southern part of the Orange Free State. It was distinguished from other zebras by having the usual vivid marks on the front part of the body only. In the mid-section, the stripes faded and the dark, inter-stripe spaces became wider, and the hindquarters were a plain brown. The name comes from a Khoikhoi word for zebra and is onomatopoeic, being said to resemble the quagga's call. 

The quagga was originally classified as an individual species, Equus quagga, in 1788. Over the next fifty years or so, many other zebras were described by naturalists and explorers. Because of the great variation in coat patterns (no two zebras are alike), taxonomists were left with a great number of described "species", and no easy way to tell which of these were true species, which were subspecies, and which were simply natural variants. Long before this confusion was sorted out, the quagga had been hunted to extinction for meat, hides, and to preserve feed for domesticated stock. The last wild quagga was probably shot in the late 1870s, and the last specimen in captivity died on August 12, 1883 at the Artis Magistra zoo in Amsterdam. 

Because of the great confusion between different zebra species, particularly among the general public, the quagga had become extinct before it was realized that it appeared to be a separate species. The quagga was the first extinct creature to have its DNA studied. Recent genetic research at the Smithsonian Institution has demonstrated that the quagga was in fact not a separate species at all, but diverged from the extremely variable plains zebra. 


Thylacine: the Tasmanian Tiger (extinct since 1936)

Resultado de imagem para the Tasmanian Tiger

The Thylacine was the largest known carnivorous marsupial of modern times. Native to Australia and New Guinea, it is thought to have become extinct in the 20th century. It is commonly known as the Tasmanian Tiger (due to its striped back), and also known as the Tasmanian Wolf, and colloquially the Tassie (or Tazzy) Tiger or simply the Tiger. It was the last extant member of its genus, Thylacinus, although a number of related species have been found in the fossil record dating back to the early Miocene. 

The Thylacine became extinct on the Australian mainland thousands of years before European settlement of the continent, but survived on the island of Tasmania along with a number of other endemic species such as the Tasmanian Devil. Intensive hunting encouraged by bounties is generally blamed for its extinction, but other contributory factors may have been disease, the introduction of dogs, and human encroachment into its habitat. Despite being officially classified as extinct, sightings are still reported. 



Steller's Sea Cow: the defenseless beast (extinct since 1768) 

Formerly found near the Asiatic coast of the Bering Sea, it was discovered in in 1741 by the naturalist Georg Steller, who was traveling with the explorer Vitus Bering. The sea cow grew up to 7.9 meters (25.9 ft) long and weighed up to three tons, much larger than the manatee or dugong. It looked somewhat like a large seal, but had two stout forelimbs and a whale-like tail. According to Steller, "The animal never comes out on shore, but always lives in the water. Its skin is black and thick, like the bark of an old oak..., its head in proportion to the body is small..., it has no teeth, but only two flat white bones—one above, the other below". It was completely tame, according to Steller. Fossils indicate that Steller's Sea Cow was formerly widespread along the North Pacific coast, reaching south to Japan and California. Given the rapidity with which its last population was eliminated, it is likely that the arrival of humans in the area was the cause of its extinction elsewhere as well. There are still sporadic reports of sea cow-like animals from the Bering area and Greenland, so it has been suggested that small populations of the animal may have survived to the present day. This remains so far unproven. 


Irish Deer: the largest deer that ever lived (extinct about 7,700 years ago) - Photo: (c) The Field Museum, CK1T]

The Irish Elk or Giant Deer, was the largest deer that ever lived. It lived in Eurasia, from Ireland to east of Lake Baikal, during the Late Pleistocene and early Holocene. The latest known remains of the species have been carbon dated to about 5,700 BC, or about 7,700 years ago. The Giant Deer is famous for its formidable size (about 2.1 meters or 7 feet tall at the shoulders), and in particular for having the largest antlers of any known cervid (a maximum of 3.65 meters/12 feet from tip to tip and weighing up to 90 pounds). 

Discussion of the cause of their extinction has still focused on the antlers (rather than on their overall body size), which may be due more to their impact on the observer than any actual property. Some have suggested hunting by man was a contributing factor in the demise of the Irish Elk as it was with many prehistoric megafauna, even assuming that the large antler size restricted the movement of males through forested regions or that it was by some other means a "maladaptation". But evidence for overhunting is equivocal, and as a continental species, it would have co-evolved with humans throughout its existence and presumably have adapted to their presence. 


Caspian Tiger: the third largest (extinct since 1970)

Resultado de imagem para Caspian Tiger

The Caspian tiger or Persian tiger was the westernmost subspecies of tiger, found in Iran, Iraq, Afghanistan, Turkey, Mongolia, Kazakhstan, Caucasus, Tajikistan, Turkmenistan and Uzbekistan until it apparently became extinct in the 1970s. Of all the tigers known to the world, the Caspian tiger was the third largest. 

The body of this subspecies was quite stocky and elongated with strong legs, big wide paws and unusually large claws. The ears were short and small, and gave the appearance of being without hair on the tips. Around the cheeks the Caspian tiger was generously furred and the rest of its fur was long and thick. The colouration resembled that of the Bengal tiger. Male Caspian tigers were very large and weighed 169-240 kg. Females were not as large, weighing 85-135 kg. There are still occasional claims of the Caspian tiger being sighted. 

Aurochs: a very large type of cattle (extinct since 1627)

One of Europe's most famous extinct animals, the aurochs or urus (Bos primigenius) were a very large type of cattle. Aurochs evolved in India some two million years ago, migrated into the Middle East and further into Asia, and reached Europe about 250,000 years ago.

10 Unbelievable NASA Missions That Never Happened

This mission truly would have lived up to its name: a product of a late 1980s collaboration between NASA and the U.S. Navy, it involved an unmanned one-way interstellar voyage to one of the nearest stars to us, Alpha Centauri B.
Here, the science fiction quotient goes off the scale: the probe would have been powered by a fission drive based upon the Orion project, known as nuclear pulse propulsion. Essentially, the ship would be propelled forward at about 4.5 percent of the speed of light by a series of constant nuclear explosions out of the back of the ship.Traveling at that speed, the probe would reach Alpha Centauri B in just about 100 years. And any data it sent back home using a laser beam travelling at the speed of light would take a little over four years to get to Earth.
Naturally, the project was never explored beyond the conceptual stage due to the prohibitive cost of building such a large spacecraft, and concerns over sending a large payload of nuclear warheads into space.
Ever seen Mobile Suit Gundam? Or (spoilers) do you remember that American space colony at the end of Interstellar? Those were both based upon a design NASA thought about working with in the 1970s.
Also known as O’Neill Cylinders after their designer, physicist Gerard K. O’Neill. Each colony was set up to spin to create gravity by centrifugal force. Also, the colonies themselves would have been capable of holding around 10,000 people each, and would be placed in stable orbits around the sun at LaGrange points just outside the moon’s orbit. They would have been created largely from materials shipped from the moon, which logically would also first require a thriving moon colony to support these cylinders’ construction.
However, technical know-how never really caught up with vision, and these space colonies never came to pass. To put things in perspective, creating the outlandish-sounding Project Longshot described above would have been a complete cakewalk compared to creating just one of these space colonies, even with modern technology. 
For this one, we’ll dial down the ambition a bit, but only just. This mission comes out of what was known as the Apollo Applications Program, which was basically a way for NASA to get the most out of its Apollo equipment by repurposing it for things other than moon missions. Here, using favorable orbital positions in 1975, a low-consumption trajectory would bring three astronauts toward Mars long enough for them to observe it from orbit and drop some probes to take samples and collect data before slingshotting them back home again.
Congress put the kibosh on this one in favor of increasing cooperation with the Soviets (see the famous 1975 Apollo/Soyuz docking mission), and pursuing a less costly Apollo Applications Program venture: the Skylab space station. 
A second Apollo Applications Program mission would involve going deeper into the solar system and attempting to send humans on a flight to a deathworld closer to the Sun: Venus.
The trip, slated to launch in 1973, would take approximately a year to complete. The crew wouldn’t land on Venus, as its crushing atmospheric pressure and literal acid rain would be instantly fatal. Instead, the crew would make detailed observations of the atmosphere and planet surface from orbit, as well as observe Mercury since it would be in near alignment with Venus during the mission.
And, for bonus points, this Venus flyby could be combined with the aforementioned Mars flyby mission to take advantage of orbital positions. It would just add year and a half or so to the mission clock.
Like the Mars flyby option, this one was bypassed in favor of lower cost unmanned probe missions, as well as more politically and technically practical missions in low Earth orbit.
Stepping back a bit to the Moon Shot days, NASA hired General Motors to create a sort of moon Cadillac large enough to hold two astronauts in comparative comfort for up to two weeks (or three astronauts for a slightly shorter amount of time).
The idea was basically to give moon explorers a mobile base with lots of equipment so they could check out the far corners of the moon more efficiently. And despite the exotic nature of the the Mobile Geological Laboratory (or MOLAB, its official designation), the engine it would have used at its core was essentially what you’d find in a stock Chevy Corvair.
Once again, cost was the main drawback and the government pulled the plug on the project by 1968. Another nail in the coffin was flagging support for a full-fledged moon base, which the MOLAB would require for logistical support. Unlike the much smaller Lunar Roving Vehicle, it was far too expensive to use once and abandon on the moon.
In addition, getting that much mass into orbit was another concern, as NASA’s supply of the huge Saturn V rockets was nearly exhausted by the late 60s.
This one’s pretty interesting in that it may be getting a second lease on life with the newly-announced NASA project to create a probe set to head to Europa in the mid-2020s. However, that soon may change given the recent, far more optimistic indications of liquid water on Saturn’s moon Enceladus, but I digress.
The JIMO probe was a product of the early 2000s and in addition to Europa, was slated to check out the other Galilean moons of Ganymede and Callisto for subsurface oceans. The craft itself would have been powered by a nuclear fission reactor, as opposed to the radioisotope thermoelectric generators current space probes are equipped with, which create electrical power by harnessing the energy released by decaying radioactive material.
The mission was ultimately canceled because of NASA’s priority shift to focusing on returning humans to the moon. Also, as seen above with Project Longshot, people weren’t exactly keen on putting a fully-functional nuclear reactor into space, either.
Fact one: You can only get the Internet on Earth. Fact two: transmitting data via radio from Mars to Earth is very slow and arduous. Conclusion: Let’s bring the Internet to Mars.
Believe it or not, NASA was planning in the early 2000s to create a satellite uplink in Mars orbit that would literally bring the data volume and speed of the Internet to an interplanetary probe mission, greatly aiding in relaying mission data. The really neat thing about the MTO would have been that it would serve as a communications hub for all current and future missions on Mars: all probes would have benefitted from increased speed and bandwidth.
Unfortunately, this project was canceled in 2005 to free up funding for more conventional NASA needs, such as a repair and servicing mission for the Hubble Space Telescope, and two other Mars missions, the Mars Exploration Rover and the Mars Science Laboratory. 
Much like the JIMO project, this one was shelved at first after it was deemed to expensive, and then revived years later with a series of separate probe missions in the 2000s.
Designed and planned during the Ronald Reagan years, CRAF was supposed to do a flyby of an asteroid and then speed on over to a comet, match its speed and course, and fly alongside it, relaying data, for three years. As they say, with great ambition comes great budgets, and the project was canceled in the mid-1990s after racking up a much larger-than-anticipated bill.
But all was not lost: NASA’s Stardust mission from the early 2000s managed to collect samples from an asteroid and return them to Earth, and NASA’s Deep Impact mission (no relation to the movie) from the mid-2000s conducted the first comprehensive survey of a comet’s composition. 
Since the early 1970s, no human has ever set foot on another planetary body, and those who have are rapidly dying off. It was against that grim backdrop for manned space exploration that the Bush administration set out to put a base on the moon to be completed by 2024.The plan was called the Vision for Space Exploration, and was almost immediately attacked for not focusing on further exploration of planets and moons within the solar system. Even second man on the moon Buzz Aldrin disagreed with NASA on this one, arguing for a mission to put humans on Mars instead.
Flash forward six years and one president later, and in 2010 the Obama administration decided to defund the 21st century American moon shot plan. NASA was mandated to focus its efforts instead on creating a Saturn V-type heavy lift rocket and space shuttle replacement in order to focus on a manned asteroid mission around 2025 and a human Mars landing around 2035.
Only time will tell as to whether a future president will align NASA with the moon once again, or if the U.S.’s moon exploration era is over for good. 
This one’s particularly neat, as it would involve putting a small submarine and/or boat on the surface of Titan, one of the largest moons in the solar system and the one with the thickest atmosphere and a large amount of seas…of liquid hydrocarbons.
The Titan Mare Explorer (TiME) would essentially be a buoy, dropped into one of the moon’s many large methane lakes. Its mission would have been to study the composition of the methane lakes, as well as how the liquid methane interacts with the gaseous methane in Titan’s atmosphere. Most intriguingly, TiME might have been able to provide some insights into how life could flourish in a methane-based ecology.
Unfortunately, the TiME program, like many NASA projects, was competing for its funding with a Mars lander mission and a comet rendezvous mission.
The Titan Mare Explorer failed to make the cut, and instead of a space boat mission to Titan in 2016, we’ll be seeing another Mars shot, called InSight.
However, that still purports to be plenty exciting, as InSight’s mission will be to delve further into why the Red Planet seems to be outgassing methane from underground.
