It's Robinson Crusoe on Mars, 21st century style. Set aside a chunk of free time when you start this one. You're going to need it because you won't want to put it down. The result is a story that is as plausible as it is compelling. I guess someone will find it eventually. Maybe a hundred years from now. Just not on Sol 6 when everyone thinks I did.
Mankind reaching out to Mars to send people to another planet for the very first time and expand the horizons of humanity blah, blah, blah. The Ares 1 crew did their thing and came back heroes. They got the parades and fame and love of the world. Ares 2 did the same thing, in a different location on Mars. They got a firm handshake and a hot cup of coffee when they got home. Well, that was my mission. Okay, not mine per se. Commander Lewis was in charge. I was just one of her crew. Actually, I was the very lowest ranked member of the crew.
I wonder if this log will be recovered before the rest of the crew die of old age.
I presume they got back to Earth all right. You did what you had to do. In your position I would have done the same thing. I guess I should explain how Mars missions work, for any layman who may be reading this. We got to Earth orbit the normal way, through an ordinary ship to Hermes. All the Ares missions use Hermes to get to and from Mars. Once we got to Hermes, four additional unmanned missions brought us fuel and supplies while we prepared for our trip.
Once everything was a go, we set out for Mars. But not very fast. Gone are the days of heavy chemical fuel burns and trans-Mars injection orbits. Hermes is powered by ion engines. They throw argon out the back of the ship really fast to get a tiny amount of acceleration. Suffice it to say we got to Mars days later without strangling each other.
From there, we took the MDV Mars descent vehicle to the surface. The MDV is basically a big can with some light thrusters and parachutes attached.
Its sole purpose is to get six humans from Mars orbit to the surface without killing any of them. A total of fourteen unmanned missions deposited everything we would need for surface operations. They tried their best to land all the supply vessels in the same general area, and did a reasonably good job. But they tend to bounce around a lot.
Start to finish, including supply missions, a Mars mission takes about three years. In fact, there were Ares 3 supplies en route to Mars while the Ares 2 crew were on their way home. The most important piece of the advance supplies, of course, was the MAV. The Mars ascent vehicle. That was how we would get back to Hermes after surface operations were complete. The MAV was soft-landed as opposed to the balloon bounce-fest the other supplies had. Of course, it was in constant communication with Houston, and if there had been any problems with it, we would have passed by Mars and gone home without ever landing.
The MAV is pretty cool. Turns out, through a neat set of chemical reactions with the Martian atmosphere, for every kilogram of hydrogen you bring to Mars, you can make thirteen kilograms of fuel. It takes twenty-four months to fill the tank. It was a ridiculous sequence of events that led to me almost dying, and an even more ridiculous sequence that led to me surviving. The mission is designed to handle sandstorm gusts up to kph.
So Houston got understandably nervous when we got whacked with kph winds. We all got in our flight space suits and huddled in the middle of the Hab, just in case it lost pressure. The MAV is a spaceship. It has a lot of delicate parts. After an hour and a half of sustained wind, NASA gave the order to abort.
We had to go out in the storm to get from the Hab to the MAV. That was going to be risky, but what choice did we have? Our main communications dish, which relayed signals from the Hab to Hermes, acted like a parachute, getting torn from its foundation and carried with the torrent. Along the way, it crashed through the reception antenna array. Then one of those long thin antennae slammed into me end-first. It tore through my suit like a bullet through butter, and I felt the worst pain of my life as it ripped open my side.
I vaguely remember having the wind knocked out of me pulled out of me, really and my ears popping painfully as the pressure of my suit escaped. I awoke to the oxygen alarm in my suit. A steady, obnoxious beeping that eventually roused me from a deep and profound desire to just fucking die. The storm had abated; I was facedown, almost totally buried in sand.
The antenna had enough force to punch through the suit and my side, but it had been stopped by my pelvis. So there was only one hole in the suit and a hole in me, of course. I had been knocked back quite a ways and rolled down a steep hill. Somehow I landed facedown, which forced the antenna to a strongly oblique angle that put a lot of torque on the hole in the suit.
It made a weak seal. Then, the copious blood from my wound trickled down toward the hole. As the blood reached the site of the breach, the water in it quickly evaporated from the airflow and low pressure, leaving a gunky residue behind.
More blood came in behind it and was also reduced to gunk. Eventually, it sealed the gaps around the hole and reduced the leak to something the suit could counteract. The suit did its job admirably. Sensing the drop in pressure, it constantly flooded itself with air from my nitrogen tank to equalize. Once the leak became manageable, it only had to trickle new air in slowly to relieve the air lost.
After a while, the CO2 carbon dioxide absorbers in the suit were expended. Not the amount of oxygen you bring with you, but the amount of CO2 you can remove. In the Hab, I have the oxygenator, a large piece of equipment that breaks apart CO2 to give the oxygen back. But the space suits have to be portable, so they use a simple chemical absorption process with expendable filters. Between the breach and the bloodletting, it quickly ran out of nitrogen. All it had left was my oxygen tank. So it did the only thing it could to keep me alive.
It started backfilling with pure oxygen. I now risked dying from oxygen toxicity, as the excessively high amount of oxygen threatened to burn up my nervous system, lungs, and eyes. An ironic death for someone with a leaky space suit: Every step of the way would have had beeping alarms, alerts, and warnings. But it was the high-oxygen warning that woke me. The sheer volume of training for a space mission is astounding.
I knew what to do. Carefully reaching to the side of my helmet, I got the breach kit. The idea is you have the valve open and stick the wide end over a hole. The tricky part was getting the antenna out of the way. I pulled it out as fast as I could, wincing as the sudden pressure drop dizzied me and made the wound in my side scream in agony.
I got the breach kit over the hole and sealed it.
The suit backfilled the missing air with yet more oxygen. Checking my arm readouts, I saw the suit was now at 85 percent oxygen. I stumbled up the hill back toward the Hab. As I crested the rise, I saw something that made me very happy and something that made me very sad: The Hab was intact yay! Right that moment I knew I was screwed. I limped back to the Hab and fumbled my way into an airlock. As soon as it equalized, I threw off my helmet. Once inside the Hab, I doffed the suit and got my first good look at the injury. It would need stitches. Fortunately, all of us had been trained in basic medical procedures, and the Hab had excellent medical supplies.
A quick shot of local anesthetic, irrigate the wound, nine stitches, and I was done. I knew it was hopeless, but I tried firing up the communications array. No signal, of course. The primary satellite dish had broken off, remember? And it took the reception antennae with it. The Hab had secondary and tertiary communications systems, but they were both just for talking to the MAV, which would use its much more powerful systems to relay to Hermes.
Thing is, that only works if the MAV is still around. I had no way to talk to Hermes.
In time, I could locate the dish out on the surface, but it would take weeks for me to rig up any repairs, and that would be too late. In an abort, Hermes would leave orbit within twenty-four hours. The orbital dynamics made the trip safer and shorter the earlier you left, so why wait? Checking out my suit, I saw the antenna had plowed through my bio-monitor computer.
The rest of the crew would have seen the pressure in my suit drop to nearly zero, followed immediately by my bio-signs going flat. Add to that watching me tumble down a hill with a spear through me in the middle of a sandstorm. They thought I was dead. Near a canal, the men find a strange, deserted city thousands of years old.

Martian soil is the fine regolith found on the surface of Mars. Its properties can differ significantly from those of terrestrial soil, including its toxicity due to the presence of perchlorates. The term Martian soil typically refers to the finer fraction of regolith. On Earth, the term "soil" usually includes organic content. This approach enables agreement across Martian remote sensing methods that span the electromagnetic spec Tweel is an airless tire design concept developed by the French tire company Michelin.

Weinbaum is series of short stories, published in Wonder Stories and Astounding Stories in the s, which are set upon various planets and moons of the Solar System. The stories are marked by attention to the detail of the alien ecosystems with which Weinbaum equips his planets. Though only a few of the stories share protagonists, there is enough shared detail between the stories to show that they belong to a common fictional universe.
In Weinbaum's Solar System, in accordance with the then-current near-collision hypothesis, the gas giants radiate heat, enough to warm their satellites to Earthlike temperatures, allowing for Earthlike environments on Io, Europa, Titan, and even Uranus.

Weinbaum is a collection of science fiction stories by Stanley G. Weinbaum, published in as an original paperback by Ballantine Books. The volume included an introduction by Isaac Asimov and an afterword by Robert Bloch. Ballantine reissued the collection twice in the later s; Garland Publishing published a library hardcover edition in , and Sphere Books released a UK market edition in , under the title A Martian Odyssey and Other Stories.

A month after the events in "Parasite Planet", Hamilton "Ham" Hammond and Patricia Burlingame are married, and thanks to Burlingame's connections, the two have been commissioned by the Royal Society and the Smithsonian Institution to explore the night side of Venus.
There they find a species of warm-blooded mobile plants with a communal intelligence that Burlingame nicknames Oscar. Oscar is very intelligent, quickly picking up English from Hammond and Burlingame. The humans learn that the Oscar beings reproduce by releasing clear bubbles full of gaseous spores. When the bubbles burst, the spores come to rest on another Oscar being, eventually grow into another individual, and bud off.
The monster is created by an unorthodox biology experiment. Biology appears in fiction, especially but not only in science fiction, both in the shape of real aspects of the science, used as themes or plot devices, and in the form of fictional elements, whether fictional extensions or applications of biological theory, or through the invention of fictional organisms. Major aspects of biology found in fiction include evolution, disease, genetics, parasitism and symbiosis mutualism , and ecology.
Speculative evolution enables authors with sufficient skill to create what the critic Helen N. Parker calls biological parables, illuminating the human condition from an alien viewpoint. Fictional alien animals and plants, especially humanoids, have frequently been created simply to provide entertaining monsters.

It has attracted sustained study from planetologists and climatologists.
While Mars's climate has similarities to Earth's, including periodic ice ages, there are also important differences, such as much lower thermal inertia. The climate is of considerable relevance to the question of whether life is or was present on the planet. The climate briefly received more interest in the news due to NASA measurements i Wonder Stories is an early American science fiction magazine which was published under several titles from to It was founded by Hugo Gernsback in after he had lost control of his first science fiction magazine, Amazing Stories, when his media company Experimenter Publishing went bankrupt.

Mars' surface conditions and past presence of water make it arguably the most hospitable planet in the Solar System besides Earth. Mars requires less energy per unit mass delta-v to reach from Earth than any planet, except Venus. Permanent human habitation on other planets, including Mars, is one of science fiction's most prevalent themes. As technology advances, and concerns about humanity's future on Earth increase, arguments favoring space colonization gain momentum.
Both private and public organizations have made c Fictional representations of Mars have been popular for over a century. Interest in Mars has been stimulated by the planet's dramatic red color, by early scientific speculations that its surface conditions might be capable of supporting life, and by the possibility that Mars could be colonized by humans in the future. Almost as popular as stories about Mars are stories about Martians engaging in activity frequently invasions away from their home planet.
In the 20th century, actual spaceflights to the planet Mars, including seminal events such as the first man-made object to impact the surface of Mars in , and then later the first landing of "the first mechanized device to successfully operate on Mars" in in the Viking program by the United States , inspired a great deal of interest in Mars-related fiction.
Exploration of the planet Curiosity's self-portrait at "Rocknest" October 31, The planet Mars has been explored remotely by spacecraft. Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential.
Roughly two-thirds of all spacecraft destined for Mars failed before completing their missions and some failed before their observations could begin. Some missions have met with unexpected success, such as the twin Mars Exploration Rovers, which operated for years beyond their specification.
Mock-up of canceled Mars Surveyor rover, based on Mars Pathfinder's Sojourner The Mars Surveyor project was a multi-part Mars exploration mission intended as a follow-up to Mars Surveyor After the two probes of the project, Mars Climate Orbiter and Mars Polar Lander, were both lost, NASA's "better, faster, cheaper" exploration philosophy was re-evaluated, with a particular eye on the two project probes. As a result, the Mars Surveyor Lander was canceled in May , but the decision was made to go ahead with its orbiter counterpart.

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the "Red Planet"[15][16] because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons.
Mars is the site of Olympus Mons, the largest volcano and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. Part of NASA's Mars Surveyor program, it returns geological data about Mars's surface such as identifying elements and the location of water. This instrument has mapped the distribution surface hydrogen, thought to trace water in the surface layer of Martian soil. Along with its cooler, it measures by by millimetres The detector is a photodiode made of a 1. The possibility of life on Mars is a subject of significant interest to astrobiology due to its proximity and similarities to Earth.
To date, no proof has been found of past or present life on Mars. Cumulative evidence shows that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms. The existence of habitable conditions does not necessarily indicate the presence of life. Scientific searches for evidence of life began in the 19th century, and they continue today via telescopic investigations and deployed probes. While early work focused on phenomenology and bordered on fantasy, the modern scientific inquiry has emphasized the search for water, chemical biosignatures in the soil and rocks at the planet's surface, and biomarker gases in the atmosphere.
This is especially so since Mars has a cold climate and la Weinbaum that was first published in the October issue of Astounding Stories. Plot summary Uranus from space. Following his expedition to the night side of Venus, the Smithsonian Institution appoints Hamilton "Ham" Hammond to head an expedition to Uranus. In Weinbaum's version of the Solar System, all of the gas giants generate significant amounts of infrared radiation, enough to produce Earthlike environments on the inner moons of Jupiter and Saturn and on the surface of Uranus itself.
At the time "The Planet of Doubt" takes place at the turn of the 22nd century, the limited range of the spaceships ensures that Uranus can only be reached from the American base on Titan when Saturn reaches conjunction with Uranus, an event that occurs once every forty years.

An extraterrestrial or alien is any extraterrestrial lifeform; a lifeform that did not originate on Earth. The word extraterrestrial means "outside Earth". The first published use of extraterrestrial as a noun occurred in , during the Golden Age of Science Fiction. Science fiction aliens are both metaphors and real possibilities. One can probe the nature of humanity with aliens that by contrast illustrate and comment upon human nature.
Still, as evidenced by widespread belief in alien visitors see UFOs and efforts to detect extraterrestrial radio signals, humans also crave companionship in a vast, cold universe and aliens may represent hopeful, compensatory images of the strange friends we have been unable to find. Thus, aliens will likely remain a central theme in science fiction until we actually encounter th The Red Peri is a collection of science fiction short stories by author Stanley G.
