Atom bombs are just the beginning. In the last half-century, the greatest military minds on Earth have developed an arsenal of weapons to make mutually assured destruction seem tame.

Whether these masterpieces of destruction come from miles above Earth or millimeters below the skin, they have one thing in common: they're spooky as hell.

By the time Lieutenant Colonel Michael Brill touched down after a combat mission over Iraq earlier today, he had broken his own world record for the most hours spent flying the F-16 Fighting Falcon. Brill, a 421st Expeditionary Fighter Squadron pilot, has logged more than 6,000 hours in the F-16.

We've talked in this space in the past few months about detecting the existence of Earth-like planets in other solar systems, and on the educated guesswork which goes into putting a number on the probability of intelligent life existing out there as well. You may remember that the discovery of terrestrial planets is well on its way as technology improves; and that the Drake equation—with all its assumptions—has proved to be remarkably accurate.

I don't know about you, but when airline pilots organize themselves enough to protest their employer's overall poor performance—not, I'd like to point out, merely their crappy pay—that gets my attention. That's precisely what hundreds of American Airlines pilots intend to do tomorrow in nine cities around the country. They'll be demonstrating at major airports to "encourage passengers to help AA employees get management's attention" to fix problems relating to performance and customer service. Specifically, American has the worst on-time performance among network carriers. The pilots are also, naturally, not particularly amused about the nose-gear-wiring fiasco that grounded hundreds of aircraft and caused countless traveler delays last week.

Today marks the 18th anniversary of the launch of the Hubble Space Telescope, and to celebrate, NASA has released a collection of 59 new Hubble images (under the fantastic title "Galxies Gone Wild!") that present galaxies in all of their volatile wonder.

If a sodden rice paddy feels soft and forgiving underfoot, it is not a merciful place to set down an airplane at 200 mph. And that’s only one of Mike Selby’s reasons to look nervous as he watches his A-10 Warthog—a 10-foot-wide, 65-pound, hand-built model—begin its maiden takeoff roll down a rough asphalt runway near Bangkok, Thailand. Selby, who spent over $12,000 and the better part of a year fabricating and building this radio-controlled jet, stands runwayside with his thumbs hooked into the belt loops of his jeans, trying to look relaxed as he draws on a Cuban cigar.

The small airplane is too dirty for an environmentally threatened world. That’s not the view from eco-activists, but from some of the leading lights in general aviation—the category encompassing small planes such as Cessnas flown by citizen pilots. “At some point, some environmental group is going to figure out that small aircraft fly leaded fuel,” said Mark Moore, NASA’s personal air vehicle program manager, to a meeting of engineers, aviation advocates and a billionaire corporate titan with his own private jet. Their goal, however, is not to bury private aviation, but to remake it as the greenest form of personal transit.

Granted, it might not seem like such a big deal when astronomers find some of the missing mass in the universe, since there's very little that isn't missing. Roughly 95 percent of the cosmos is either dark matter or dark energy. About five percent of the universe is made up of the normal mass we're familiar with—baryonic matter. Yet by adding up the known stars and galaxies and gas, astronomers have only accounted for about half of that five percent.

The Winnebago isn’t exactly a marvel of technology. But there’s a good chance that NASA’s next generation of lunar travelers will live and work out of a two-piece system—a mobile robot and habitat combination that will allow astronauts to bring base camp with them—that has plenty in common with the humble RV.

Last April, we dissected the world’s most advanced fighter jet, the F-35B Lightning II, in the pages of our annual “How It Works” issue. Now military contractor Lockheed Martin is firing up the jet’s 40,000-pound-thrust engine (the most powerful ever built for a fighter jet) in preparation for flight tests. The jet can soar at supersonic speeds (1,000 mph) and deflect radar signals, but by the end of the month, pilots are expected to show off its most highly anticipated feature: the ability to stop mid-flight and touch down virtually anywhere.
