The Martian Express
One of the more intriguing theories to fall out of the early gravity-assist research was a hypothetical spacecraft called the Cycler, a vehicle which could utilize gravity to cycle between two bodies indefinitely– Earth and Mars, for instance– with little or no fuel consumption. Even before the complex orbital mathematics were within the grasp of science, tinkerers speculated that a small fleet of Cyclers might one day provide regular bus service to Mars, toting men and equipment to and from the Red Planet every few months. Though this interplanetary ferry may sound a bit like perpetual-motion poppycock, one of the concept’s chief designers and proponents is a man who is intimately familiar with aggressive-yet-successful outer-space endeavors: scientist/astronaut Dr. Buzz Aldrin.

The Third Reich’s Diabolical Orbiting Superweapon
When Germany surrendered in May 1945, the scientists at Hillersleben were forced to abandon an assortment of death-bringing innovations at various stages of completion. Among these were a rocket-assisted artillery shell which had 50% more range than standard artillery, a 600mm mortar which fired one-ton self-propelled projectiles for up to three and a half miles, a modified Tiger tank which could fire 760-pound rockets up to six miles, and a chain-like projectile made up of small, linked rockets with a range of 100 miles. But the military masterminds’ most sinister ambitions were embodied in their behemoth Sonnengewehr, or “Sun Gun” project– an orbital weapon intended to exact fiery punishment upon the enemies of the Third Reich, forever establishing their dominance over the genetically inferior Untermenschen of the Earth.

The Origami Resolution
His intricate paper insect creations were a departure from the standard boats and cranes that have long been the tradition of origami. Over time his works grew more complex, featuring hundreds of folds and multiple pieces of paper, such as a full-scale cuckoo clock. Between his efforts to earn a PhD in applied physics, his job at NASA’s Jet Propulsion laboratory, his eighty technical papers, and his forty-six patents in optoelectronics and lasers, he somehow found time to implement and evolve a number of original origami designs.
The practicality of his scientific research began to influence his origami designs, until the line between the two began to blur. He participated in a project at EASi Engineering to develop complicated crease patterns for airbag folding designs. Lang also worked to design a mesh wire heart support to be folded and implanted in congestive heart failure patients; once inside, it would expand, protecting the heart. His most ambitious project to date, however, is shared with a team at the Lawrence Livermore National Laboratory, with whom he has developed a space telescope – one that is forty times larger than the Hubble and collapsible for space travel through a series of precise origami folds.

Space Radio: More Static, Less Talk
Purveyors of science fiction are fond of exploring the ramifications of this radio leakage, suggesting that someday an advanced alien race might materialize to befriend, enslave, or destroy humanity after a little electromagnetic eavesdropping from afar. Indeed, if there happen to be any radio-savvy civilizations within 114 light years of Earth– an area which encompasses roughly fifteen thousand stars– humanity’s earliest meaningful transmissions will have already reached them.
Similar speculation appears in science non-fiction, such as the Search for Extra-Terrestrial Intelligence (SETI) project, which strains its giant radio ears for extraterrestrial signals. When consulting the wisdom of probability, one finds that the universe ought to be teeming with technology-toting aliens; but aside from a couple of interesting-but-inconclusive detections, no discernibly intelligent patterns have ever been observed by Earth’s space-listening instruments. One might surmise that the conspicuous silence is “evidence of absence,” but such a conclusion might be a bit premature under the circumstances. Read the rest of this Article ▶
The Daedalus Starship
In order to reach even the nearest stars within the allotted fifty-year window, the thirteen scientists and engineers of the research group had a formidable task ahead of them. Their space probe would be required to accelerate to astonishing speeds, and it would need to weather the constant battering of particles from the soup of space debris known as the Interstellar Medium. In spite of these problems, in 1978 the organization presented a highly developed spaceship concept which may yet prove to be the model for future interstellar travel. It was called Project Daedalus.

Outer Space Exposure
As is true with many subjects, this representation in popular culture does not reflect the reality of exposure to outer space. Ever since humanity first began to probe outside of our protective atmosphere, a number of live organisms have been exposed to vacuum, both deliberately and otherwise. By combining these experiences with our knowledge of outer space, scientists have a pretty clear idea of what would happen if an unprotected human slipped into the cold, airless void.

How I Learned to Stop Worrying and Love the Atomic Spaceship
Though man was the master of the Earth, only once had he managed to explore beyond the confines of the atmosphere, in the form of a beachball-sized spacecraft called Sputnik. Werner von Braun’s rocket men had drawn up plans for spacecraft that would launch humans into orbit, but even then it was clear that inefficient chemical rockets would allow only a few to enter space; the rest of mankind would be mere spectators. Fresh from their success with the atomic bomb, a small team of Manhattan Project physicists gathered to try and change all that. Working in secret within the brand new Advanced Research Projects Agency (ARPA, now called DARPA), they designed and tested an enormously ambitious nuclear spaceship concept that would have made everything the Soviets and NASA were doing seem like hobby rockets in comparison. The codename was Project Orion. Read the rest of this Article ▶
An Astronomical Identity Crisis
First, there are several possible ‘tenth planet’ contenders out there – objects roughly the same size as Pluto and not unreasonably far away. The major examples are Quaoar, Sedna, and “Xena”, all discovered since 2002. Several smaller, unnamed ones have been found also, and surely will not be the last.
Second– perhaps conversely– the categorization of Pluto as a planet has come to be disputed. In fact, many astronomers argue that if Pluto had been discovered only in the last few years, it would not be labelled a planet at all. Read the rest of this Short ▶
