Gemini 8 was in trouble. After completing the first space docking with another craft, it begins to spin uncontrollably. Ditching protocol, commanding officer Neil Armstrong tries an unorthodox plan.

NASA began working on lunar vehicles in the early 1960s—but the project relied more on guesswork than engineering precision. After all, no one had any idea what being on the moon would be like.

A damaged Apollo 13 was about to re-enter Earth's atmosphere amid a communications blackout. It would become the longest re-entry blackout in the history of the space program.

"Big Bertha" was one of the moon rocks brought back by the Apollo 14 crew for geological analysis. What it revealed stunned scientists.

Did you know that some of the technologies we take for granted in our kitchens were actually developed by NASA? Here are five of the best, from water filters to freeze-dried food.

The crew of Apollo 11 had made history by landing on the moon and coming back to Earth in one piece. But before the celebrations could begin, they would have to spend some time in quarantine

F/A-18 Hornets, crop dusters, Corsairs, a VariEze lookalike, raceplanes, a blimp! Planes has them all. Sure theyre cartoons and they talk, but we dare you to watch this clip without smiling.

When we read on photographer Eric Curry's Web site that he views certain machines as metaphors for values of character, honor, integrity and pride, we thought his approach would be the perfect way to illustrate the affection many Earth-dwellers have come to feel for NASAs twin Mars Exploration Rovers, which, having long outlasted their life expectancies, are still transmitting from the Martian surface.In this slideshow, Curry explains how he built our March 2010 magazine cover, shot by carefully lit shot.

In 1998, during eight tests including this one with an SR20 out of Ocotillo Wells Airport in California, engineers and pilots from Cirrus Aircraft and Ballistic Recovery Systems took the plunge. They fine-tuned many items, including how the whole-airplane parachutes rocket extracts the system, and how the slider, the white ring that travels down the cords, keeps the parachute from opening too quickly, which would damage the chute and airplane.After each deployment, the SR20 released the parachute and returned to the airport rather than stranding itself in the desert. This meant that guides had to be added to the empennage to prevent damage to the vertical and horizontal tail surfaces. "Design of the test harness and parachute release mechanism were nearly as difficult as the design of the recovery systems itself," says Jay Yeakle, a Cirrus engineer. Less complex was the animal tracking system used by wildlife management groups that located the abandoned parachutes.

If the spinning 38-foot tiltrotors of the V-22 Osprey look odd, theyll soon become more familiar. The U.S. Marine Corps begins operational use of the aircraft in September 2007. The Osprey can transport 24 combat troops or up to 20,000 pounds of cargo. With its vertical/short takeoff and landing capabilities, it can fit in tight spots like a helicopter, but can fly twice as fast. In this video, distributed by V-22 manufacturer Boeing during the 2007 Paris Airshow at Le Bourget, the Osprey is seen doing its thingflying like an airplane, taking off like a helicopter, and dropping commandos like Pez. Variants of the V-22 will be ready for use by the Air Force and Special Operations Command in 2009. Video: Boeing

The X-47B, an unmanned combat vehicle built as a demonstration aircraft for the U.S. Navy, had its inaugural flight at California's Edwards Air Force Base on February 4, 2011. The Navy hasn't committed to an operational vehicle, but is planning for the X-47B to make an unmanned aircraft carrier landing in 2013. Video: US Navy/Northrop Grumman

One of James McDonnell's early concepts, the XP-67 Moonbat was a blended-wing-body design whose performance, thanks to anemic engines, was stamped FAIL. But get a load of the demo flight (and stellar landing) filmed by the U.S. Army Air Forces Air Technical Service Command in 1944. Video: U.S. Army Air Corps

To prepare him for landing the lunar module, Neil Armstrong practiced on a training vehicle right here on Earth. It was designed to replicate flying within a gravitational pull that was 1/6 that of Earth

After the success of Apollo 11, NASA unveiled an ambitious agenda for more missions into space. But interest among the public was beginning to drop—and the Nixon administration balked at the high costs

Considered one of the most appealing fighters ever built, Lockheeds XF-90 enjoys a first-rate reputation with aviation enthusiasts something of a surprise, given that only two were ever built. While researching and writing Lockheeds Missing Link for our June/July 2008 issue, authors Jorge and Karen Escalona compiled rare footage of the XF-90 at Muroc (now Edwards) Air Force Base in California in 1949. The footage, which has no sound, includes scenes of the first XF-90 prototype being trucked to Muroc, and a brief glimpse of engineers attaching ribbonlike strips to the wing to gauge airflow patterns during preflight tests. Also seen are ground crews affixing Jet-Assisted Takeoff (JATO) canisters to the aircraft (to provide additional thrust) before Tony LeVier, Lockheeds chief test pilot, takes it for a spin. The Escalonas write: The XF-90s dashing good looks earned it movie-star status throughout the 1950sfar beyond its operational lifeattracting readers and advertisers to prominent aviation periodicals and comic books of the time.

Leonardo da Vinci's Codex on the Flight of Birds will be on view at the National Air and Space Museum in Washington, DC from September 13 through October 22, 2013. The exhibit's curator, Peter Jakab, explains the importance of this rare work.
