Earth Space Science

An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.

The Earth survived a massive attack from the invading alien fleet of the mighty Tol'konian Empire, railing on the hopes of a single spacecraft known as the Orlando. Millions of lives were spared, and the planet humanity called home was safe and secure. But chaos is the only guarantee in space, and danger lurks around every corner. For Captain Shepard, his frenetic life has finally churned to a snail's pace. Although he'd never admit it, his insatiable desire for adventure yearns for the unexpected.

Marcus may have thought his biggest problem was ensuring that they didn't alert the humans to their food creation and family expansion activities while they worked on taking over Earth, but a new threat is on the horizon. The Space Agency wants to recreate Marcus' spaceship fuel, which requires massive amounts of space dust. The problem with that is that Earth's atmosphere doesn't kill a nervous system-destroying bacteria present in the space dust. Can Marcus delay them until he can take over the planet, or will he have to change Earth's atmosphere and hope he doesn't kill everything?

40 years ago, Harlan Washington began his one-man war against the superheroes of Just Cause. One day ago, he grudgingly allied with those heroes to defend the Earth from an alien invasion. When he detonated a new kind of bomb to destroy the alien fleet, he was thrown through space and time. Now....He's lost in spacetime, dying, more alone than any human ever has been. He never expected to be rescued.

The Xortaag fleet outnumbers the humans’ five to one, and using their mind-control machine, they can use all the Earth’s military forces against their own kind. The Xortaag colony ships are only a few weeks away, and when they arrive, they'll wipe out the human race to have space and resources for their people. And as if all this wasn’t bad enough, General Planetary Genocide Maada has just laid a trap for the Earth fleet and decimated a large chunk of their forces. To make things worse, an even more sinister threat (yeah, more sinister than the Xortaags) is emerging 1500 years in the future.

Aboard the scout ship Cyclops, Hornet Squadron pauses on Saturn’s moon to take stock of their condition. Eager to rejoin Ascension, Commander Ray Fairchild risks a dangerous shuttle flight to the ship while Lieutenants Brooks and Rosenski remain on station.

Newly reinstated Captain Deborah Allen Riker (a.k.a. Admiral Dare) has been called many things over the years. Risk-averse is not one of them. When she and her badly crippled starship found themselves lost in the middle of an ocean of uncharted stars, with the fate of the galaxy on the line, facing enemies from the past, present, and future.... She did what any Riker would do....She attacked.

So far, Officer Candidate School is living up to its cutthroat reputation. Still, the merciless mental, physical, and psychological torture may be worth it for Lance Warder to have a chance to fight in space. The space that awaits isn't for the faint of heart. He'll have to shed his mental chains to prove his mettle. Because no one cares who your father is when you're faced with unknown threats in a dark, infinite void.

Ein Blick auf die Erforschung außerirdischen Lebens, die unser Verständnis des Kosmos verändert. Seit Tausenden von Jahren fragen sich die Menschen, ob sie allein im Weltall sind. Zum ersten Mal können wir nun auch die entsprechende Technologie nutzen, um das zu untersuchen. Die Frage nach anderem Leben im Universum sollte eine klare Antwort haben: ja oder nein. Aber wenn man versucht, anderswo Leben zu finden, stellt man fest, dass es nicht so einfach ist. Wie kann man es über kosmische Entfernungen hinweg finden? Was ist eigentlich Leben?

Nuestra existencia está amenazada: las glaciaciones, los impactos de asteroides, la capacidad finita de la Tierra e incluso la lejana pero inevitable muerte del Sol son riesgos de tal magnitud que, si no abandonamos la Tierra, deberemos asumir la idea de nuestra extinción. Por eso, para Michio Kaku nuestro destino yace en las estrellas, no por la curiosidad o la pasión aventurera que los humanos llevamos dentro, sino por una simple cuestión de supervivencia.
