NASA completes successful parachute drop simulation for Orion spacecraft

NASA has always used the desert as its own personal playground, and we’d imagine that its team had a blast in Arizona yesterday, as a mock parachute compartment of the Orion spacecraft was dropped from 25,000 feet above Earth. The dart-shaped object experienced free fall for 5,000 feet, at which point, drogue chutes were deployed at 20,000 feet. This was then followed by pilot chutes, which then activated the main chutes. As you’d imagine, these things are monsters: the main parachutes — three in all — each measure 116 feet wide and weigh more than 300 pounds. Better yet, the mission was successful.

Naturally, all of this is in preparation for Orion’s first test flight — currently scheduled for 2014 — where the unmanned craft will travel 15 times further than the ISS and jam through space at 20,000 mph before returning to Earth. Yesterday’s outing is merely one in a series of drop tests, and yes, it’s important to remove any unknowns from the situation: eventually, humans will be along for the ride.

Lockheed Martin Stalker drone stays airborne 48 hours using laser power, all-seeing eye gets literal (video)

Posted in: Today's Chili

Aerial drone designers have been pushing hard to get devices that can stay airborne for days. After all, what’s the point of having an observer that routinely lets its guard down? Lockheed Martin must have this question forever etched in its collective mind, as it just completed tests of a modified Stalker drone that was continually charged by laser power beamed from a ground-based source. The LaserMotive-built test was admittedly conducted in a wind tunnel, not a wind-swept battlefield, but it kept the drone aloft for more than 48 hours and was so efficient that it might even have gone indefinitely, if it weren’t for staff intentionally bringing the trial to a halt. The true test is coming next, when Lockheed Martin and LaserMotive fly the drone on laser power outdoors. Should the Stalker sail the friendly skies for long enough, it could help usher in an era of UAVs that can spot intruders at all hours — a little too close to the aircraft’s name for comfort, perhaps, but potentially vital for Special Operations troops that might not have to put themselves in danger. You can check the underpinnings of both the laser power system and the Stalker in videos after the break.

Lockheed Martin F-35 Lightning II stealth fighter cockpit demonstrator hands-on (video)

Posted in: Today's Chili

We spend hundreds of hours on board a variety of airplanes each year, most often en-route to a trade show or product launch event, but occasionally we have a rare opportunity to hop on board military aircraft, to test out unrelated products, or, even more unusually, to take a seat behind the yoke. Sadly that’s not what we’re doing today — well, not exactly. We are taking a closer look at the F-35 fighter jet at Lockheed Martin’s Fighter Demonstration Center just outside our nation’s capital, but, being in the middle of a corporate complex, there’s no actual Lightning II on hand. We were able to take a simulated ride, however — this isn’t your ordinary 4D sickness-inducing amusement park thrill. The F-35 is by far the most advanced Lockheed jet to date, with updated radar, all-internal weapons, improved tracking systems, 360-degree infrared coverage with a visor readout, and a full-stealth design, not to mention the incredibly capable glass cockpit powered by more than 9.3 million lines of software code, and an overall smoother experience for pilots that could end up spending shifts of 12 hours or longer in flight.

The F-35 has already seen plenty of field time in the US, with more than 500 flights already in 2012, and it’s set to make its way to the UK armed forces next week and the Netherlands later this year, but while the aircraft is quite familiar to the pilots tasked with flying it, the public hasn’t had an opportunity to experience Lockheed’s latest airborne warrior. We flew a simulated mission within a grounded duplicate of the flyable F-35 cockpit, and the capabilities and improvements are quite clear — you definitely don’t want to encounter an F-35 from a previous-generation aircraft. The dual 8 x 10-inch touch-enabled displays combine to give you 8 x 20 inches of real estate, with dedicated modules for the weapons systems, targeting, and navigation easily accessible — you can also move them to different panels depending on your current objective. A pair of joysticks at the left and right side provide direct access, letting you move a cursor to track enemy crafts or ground-based targets as well, and a very slick heads-up-display mounted in the helmet provides infrared mapping and instrument readouts. Overall, it seems to be an incredibly powerful system. Unfortunately, the mock-up on display here isn’t accessible to the public, but you can join us for a behind-the-scenes look just after the break.
