NASA commits to Orion-based Multi-Purpose Crew Vehicle for space exploration

There's been a lot of talk of things coming to an end at NASA lately, but there are also some new beginnings, and the space agency has now officially filled in one big gap. It's announced that the so-called Multi-Purpose Crew Vehicle (or MPCV) will be its go-to space exploration vehicle for missions beyond Low Earth Orbit -- presumably, the individual spacecraft will get names more up to the level of boldly-named vehicles like Endeavor and Atlantis. If it looks a little familiar, that's because the MPCV will be based on the Orion spacecraft that was developed under the now-canceled Constellation program and, like it, it will be built by Lockheed Martin. Once its put into service, the spacecraft will be capable of carrying four astronauts on missions up to 21 days, and it could even be used as a backup for cargo and crew delivery to the ISS -- to actually get into space, it would blast off atop a heavy lift rocket, and then splash down Apollo-style in the Pacific Ocean. Head on past the break for NASA's official announcement.

Scientist cooks up adjustable strength metals

As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg

Samsung confirms WiFi-only Galaxy Tab availability: April 10th, $350

We've already seen it turn up on a few retail sites, but Samsung has now finally officially confirmed the launch details for its WiFi-only Galaxy Tab. It will be available online and at retail stores across the US on April 10th for $349.99. Specs otherwise remain the same as the 3G version, including a 7-inch 1024 x 600 display, 32GB 16GB of internal storage (with a microSD card slot for up to an additional 32GB), rear and front-facing cameras, and Android 2.2 with support for Flash 10.1 -- from the looks of things, it's also only available with a white back. Full press release is after the break. Note: The original press release incorrectly stated that there was 32GB of internal storage. There is, in fact, only 16GB.

Commodore USA puts the new C64 up for pre-sales, unveils far-less-retrotastic VIC-Slim

Desktops Commodore USA puts the new C64 up for pre-sales, unveils far-less-retrotastic VIC-Slim By Sean Hollister posted Apr 6th 2011 8:43PM Now that Commodore USA has sufficiently piqued your curiosity with a revamped Commodore 64 prototype, it's ready to capitalize on the idea. Quite literally, we might add. $595 buys you the basic basic model with an 1.8GHz dual-core Intel Atom D525 chip, NVIDIA ION 2 graphics, 2GB of RAM and a 160GB hard drive -- which it promises to deliver by "early June" -- with hundred-dollar increments adding premium features like an additional 2GB of memory, a Blu-Ray drive, up to 1TB of storage, 802.11 b/g/n WiFi and Bluetooth. However, if you're simply looking for a compact keyboard computer (rather than reliving 80's nostalgia) there's another option on tap -- a likely rebadged thin wedge of a machine that Commodore's...
