Leaving Mars, Leaving Home by SMPritchard
Leaving Mars, Leaving Home

She was gripping onto a handhold with the treaded socks on her feet. With the fluid motion of a spacer used to maneuvering in freefall, she pushed herself into the adjoining module and braced against another handrail, gently colliding with the padded wall next to me. For a long while we both stared out of the porthole at the blackness.

“I've not been on a ship in years,” she said finally, still looking outside.

“Me neither. My last time was a trip to Deimos. I've never been on an interplanetary flight before.”

“You wouldn't think it would be too much different from orbital spaceflight,” She said, “but as soon as you leave your home's orbit, and see it shrinking to a point behind you, you realize that you're out here in the dark, on your own, with only gravity guiding you. It's a strange feeling looking out and seeing nothing but stars and blackness in every direction. You might know that one of those stars is home, but it feels infinitely far away.”

She turned to face me. “It gives you a lot of time to contemplate things.”

“Like why we're going all the way down to Earth's Moon.”

-Excerpt from my untitled short-story.

Wunda Crater by SMPritchard
Wunda Crater
Umbriel is a moon of Uranus. Dark, cold, and mysterious, our only images of this enigmatic world come from the fly-by of Voyager 2 in 1986. Wunda crater, located on the equator, stands out against the soot-colored surface, with a ring of bright material covering the basin floor. No one knows what this material is, but exposed ice is a good contender.

Swift Resolution by SMPritchard
Swift Resolution

"Over the course of several hours our ship grew from a star-like point in the distance to something recognizable as a spacecraft. And indeed, it was a ship built for space. There were no aerodynamic shapes to speak of. It consisted mainly of a 40-meter long central truss structure upon which the rest of the ship's system were attached like organs and muscles to a skeleton. The engine was a magnetic nozzle attached to a squat, toroidal tokomak fusion reactor at the far end of the truss. Also attached to the spinal truss were two large, bulbous tanks containing a cryogenic slush of deuterium, topped with smaller spherical tanks filled with helium-3. Mounted behind the massive propellant tanks along the main spinal truss, like the fletching of some massive arrow, were the ship's vast radiator fins. The fins dissipated the heat from both the engine and the power conversion system into the unfillable heat-sink of space. On the whole they gave the ship a vague insectoid appearance, with its long thin spine and broad, delicate wings. At the top of this stack sat the crew habitat, a small cluster of four inflatable living modules arranged symmetrically around a central node, all protected by small plates of multi-layered meteor and radiation shields. Aft of the habitat modules was a large cylinder containing a rotating centrifugal drum; our sleeping quarters and hygiene module. Spinning at just under 6 rpm, it provided a little less than a standard Martian gee.

After some minute attitude adjustments and brief bursts of thrust from the main engine, we had finally berthed to the interplanetary cruiser. After about a day of general housekeeping and systems checks, the small ferry detached itself and began its fall back towards its landing site. Once we had our launch window, the ground controllers began the pre-burn engine startup sequence. Coolant flooded into the reactor's superconducting magnets as the chamber was rapidly filled with ionizing deuterium and helium-3. The intense magnetic fields inside the engine squeezed the rapidly-heating plasma until the nuclei, now stripped of their shielding electrons, were close enough that their nuclear attraction overpowered their electromagnetic repulsion, and they began to merge.

A plume of superheated plasma streamed out of the engine's magnetic nozzle in a focused blue-violet jet. The burn lasted for about two days, at a gentle thirty-fourth of a gee. When the engine finally cut off, it had set us on a four-and-a-half week flight downsystem to Earth." -Excerpt from my untitled short story.

Aerostat by SMPritchard
Aerostat
I redesigned my depiction of a helium mine (it processes other gasses too, mainly hydrogen and methane, but light helium, He-3, is the most valuable). I think this looks closer to what could actually be engineered than my original concept. These floating atmospheric processors powered by a central fission reactor, with enough radioactive material to keep them running for several decades. Heat from the reactor core is also used to warm hydrogen in the aerostat, generating lift. A docking trapeze for automated transfer shuttles can be seen on the bottom of the structure, where approaching shuttles mate with the processor to extract refined gasses such as deuterium, helium-3, and methane. They top off their own propellant supplies with the excess hydrogen gathered by the platform.

Seth Pritchard
Artist | Professional | Digital Art
United States
I'm a physics student at UTSA, with a strong interest in planetary science, astrophysics, and cosmology. I have an intense passion for science, and I'm a vigorous supporter of manned space exploration and settlement. After finishing my physics degree, I plan on starting a PhD in astrophysics, and then maybe going back and getting a degree in aerospace engineering.

Eventually, I want to apply to NASA to become part of the Astronaut corps. My ultimate goal is to one day walk on Mars, and maybe even help to establish the first permanent human presence there.
