Mercedes-Benz SLS AMG Electric Drive breaks Nurburgring EV lap record
There's no question that the SLS AMG Electric Drive is faster than most EVs. However, Mercedes-Benz wants to prove that the car is fast in any category -- and it just broke a Nurburgring record to underscore its point. Merc's 751HP clean machine recently ripped through the track's Nordschleife section in 7 minutes and 56 seconds, beating a production EV record set last year by Audi's R8 E-tron. While that lap time won't rival the absolute EV record, let alone those of faster conventional cars, it puts the electric SLS firmly ahead of its peers. That may be all that matters for buyers picking up their cars this month: when you've dropped half a million dollars on a new ride, some bragging rights are in order. Video of the run awaits after the break.

NASA building Space Launch System with laser melting, adapts 3D printing for the skies (video)
As we know it, 3D printing is usually confined to small-scale projects like headphones. NASA is ever so slightly more ambitious. It's using a closely related technique from Concept Laser, selective laser melting, to build elements of its Space Launch System on a pace that wouldn't be feasible with traditional methods. By firing brief, exact laser pulses at metal powder, Concept Laser's CAD system creates solid metal parts that are geometrically complex but don't need to be welded together. The technique saves the money and time that would normally be spent on building many smaller pieces, but it could be even more vital for safety: having monolithic components reduces the points of failure that could bring the rocket down. We'll have a first inkling of how well laser melting works for NASA when the SLS' upper-stage J-2X engine goes through testing before the end of 2012, and the printed parts should receive their ultimate seal of approval with a first flight in 2017.

Production-ready Mercedes-Benz SLS AMG Electric Drive supercar unveiled
We're pretty sure we've suffered some amount of vision loss from staring at the ridiculously bright paint scheme on Mercedes-Benz SLS AMG E-Cell over the past few years. MB has rolled it out at virtually every auto show it can and we've always stopped for a gander, but now we finally have the full production version -- and it's in a slightly more tame but visually perhaps even more stunning color, a sort of chrome blue that even in the flesh looks CG rendered. It's the SLS AMG Electric Drive, it's launching next June and we have the full details after the break.

Mercedes-Benz said to be exploring SLS AMG E-Cell in roadster guise
Mercedes-Benz has already committed to bringing the SLS AMG E-Cell gullwing to dealers in 2013, but we'd advise holding back on taking out a second mortgage to pay for it until you're done reading. The Netherlands' De Telegraaf hears from an unnamed spokesperson that there's enough interest to make a roadster version of the EV supercar. What action the automaker takes depends on sales of the hardtop: if it's clear more people want an open-air experience, that's what will happen. The electric motor layout is easily transferred to a roadster, the representative says. If that E-Cell variant becomes a reality, Audi might want to hurry up and build a production-grade e-tron Spyder before Mercedes claims all of the (very niche) German electric roadster market for itself.

Dark horse set to ride into space race, strapped to world's largest solid rocket booster
Alliant Techsystems (ATK) may not be on top of your betting card, but it has plenty of shuttle motor pedigree. To compete with the likes of SpaceX, Astrium and others, it's putting that technical savvy into its Liberty system to carry seven astronauts -- or tourists -- and cargo into low earth orbit. The huge 300-foot rocket and composite crew module would use ATK's solid rocket motor, originally designed for the ill-fated Ares 1, along with EAD's Ariane 5 engine, to become the heaviest lifter in NASA's fleet. Already knee-deep in a separate project, the Space Launch System designed to send Orion into deep space, ATK would like to wean NASA off it's pricy $63 million Russian ISS hitchhikes with a cheaper option that could be mission-ready in just three years. We've heard that kind of talk before, but if Liberty pulls it off, it could give our out-world aspirations a much needed ticket to ride.

NASA preps J-2X rocket engines for second round testing, SLS creeps closer to 2017 liftoff
Forty-year old tech taking astronauts into space? Sadly, that's been the current state of our space program. But in the spirit of making one extra, giant leap for mankind, our nation's best and brightest aeronautic minds have been quietly working on a propulsion system designed to power the SLS and its Orion spacecraft payload deeper into the cosmos. NASA's been testing these next-gen J-2X rockets since last year, proving their ability to "[achieve] full flight-duration firing of 500 seconds" at sea-level and, now, in a series of second round testing, the engines will be put through their paces at high altitudes. The first of 16 planned tests are scheduled to kick off this Wednesday at the agency's Stennis Center in Mississippi and should run through to year-end. Check out the official presser after the break for a fuller breakdown of this evolution in galactic travel.

NASA's Space Launch System to rocket into deep space, unravel the universe's mysteries (video)
The folks in charge of our final frontier have just taken the wraps off their latest rocket design, dubbed the Space Launch System. Unimaginative moniker aside, NASA's prepping the SLS to take future astronauts aboard its Orion Multi-Purpose Crew Vehicle beyond Low Earth Orbit, and out into the vast reaches of our solar system. The launcher's design, as shown off in the agency's video render, was chosen specifically for its flexible architecture, allowing engineers to adapt and evolve its build based on mission requirements. The rig, which'll serve as a backup transport system for commercial and international trips to the ISS, is expected to handle a payload of up to 130 metric tons, and gains lift from a combo of liquid hydrogen and oxygen. When the SLS finally lifts off at the end of 2017, NASA claims it'll be the "first exploration-class vehicle since the Saturn V took American astronauts to the moon over 40 years ago." That's a heady legacy to follow, and while we've still got a few years to wait for the real thing, you can always check out the video below for a simulated take.

Mercedes SLS AMG E-Cell hitting dealerships in 2013
You may disagree with the car's color and its powertrain choice, but you can't argue with 528 horsepower, 649lb/ft of torque, and AWD acceleration so good it should come with a neck brace. It's a legitimately hot car, and it's legitimately coming to dealerships. Mercedes today confirmed that the SLS AMG E-Cell will be available for order at dealerships in 2013, and while no price was given, expect it to be a lot. The gasoline-powered model cost around $200,000, after all. Oh, and that citrus color? It's pretty stunning in the flesh, a matte hue that makes you go "Mmm." %Gallery-113701%

Mercedes electric SLS AMG E-Cell previewed: neck-snapping and retina-searing (video)
If ever a post needed a sunglasses warning this one is it. Check out that paint job. It's a pretty hot hue for a pretty hot car, the E-Cell, a Mercedes SLS AMG that has had its internal combustion assets stripped and replaced with not one, not two, but four electric motors. That's one per wheel, naturally, and if you add them all up you get the equivalent of 528hp, a little short of the production car's 563hp, but torque is up to 649ft/lbs from the stock car's 479 -- and being electric that's all available from the start. Sadly, though, twisting force isn't the only thing that's swelled, with this car adding a whopping 880lbs to an already heft 3,571. According to Auto Express that's had a decidedly negative effect on handling, but it does at least offer a quite respectable 125 mile range. No information yet on cost or when exactly Mercedes might put this thing into production, but earlier word was we won't see it on the streets anytime before 2013. You'd better prepare yourself now by staring at the sun for a few minutes a day, and do yourself a favor: start squinting before you click "play" on the video below.

Mercedes-Benz SLS E-Cell prototype fuels our electric dreams with 526 horses
Oh, electric supercar, why do you tease us so? Mercedes is latest to throw up a prototype of what it expects future rubber burners to look like, and its SLS E-Cell doesn't disappoint. Based on its petrol-guzzling SLS AMG model, this beast produces 526 horsepower and 649 pound-feet of torque, thanks to four motors (one for each wheel) allied to a battery array that can provide an industry-leading 480kW of juice. How fast does that get you to the magical 60mph marker? Try four seconds. There's a handsome 10-inch infotainment panel in the center console, which you may see after the break, but the best news is that this prototype can be driven now and could well turn into a production Benz at some point in 2013.
