NASA’s new cooling pump doesn’t need moving parts, set to chill out in space next month

It’s pretty easy to cool down an overheating desktop computer with an extra fan, but what do you do if there’s no air? That’s the hurdle NASA‘s engineers are hoping to clear with a new prototype pump that the agency unveiled last week. The pinkie-sized instrument relies upon a technology known as electrohydrodynamic (EHD)-based thermal control, which uses electric fields to inject coolant through small vents on a thermal cold plate, before moving the extra heat to a radiator and spreading it far away from any temperature-sensitive areas. With no moving parts, the lightweight cooler uses only about half a watt of power and can be sized to work with small electric components or lab-on-a-chip devices. The challenge is to make sure that the pump can survive the vibrations of a rocket launch, though NASA will put it to the test during a rocket mission on June 9 and in 2013, when an EHD thermal cold plate will be placed on the International Space Station. Start your countdown clock and blast past the break for a full press release.

ASUS targets Christmas for Padfone launch, hints at Ice Cream Sandwich (video hands-on)

We just got to spend some quality time with ASUS’ newly unveiled Padfone and you can see the smartphone that doubles up as a tablet on video after the break. It’s still a mere mockup for now, but ASUS has big plans for it — plans that coalesce around the Christmas period and the very latest version of Android at that time. ASUS’ Benson Lin was careful not to openly admit the company intends to ship with Ice Cream Sandwich, but he did point out that you can’t launch a smartphone with Honeycomb as the OS. We were encouraged to draw our own conclusions.

The smartphone is actually the only smart aspect of this hardware pair — the slate part acts as a display, a set of speakers, an extended battery, and an I/O extender, but it doesn’t work by itself. ASUS also tells us there’ll be other functionality enabled by the tablet panel, but that’s being kept under wraps for now. Compatibility between the display dock and subsequent phone generations is being contemplated but couldn’t be confirmed, and as to the UI, ASUS says it’ll be almost the same as its second-gen Android tablets. You heard that right, second generation ASUS Android tablets — to succeed the Transformer and Slider — will be coming around the same time as the Padfone.

ViewPad 7x aims to become world’s first 7-inch Honeycomb tablet, adds HSPA+ for good measure

Guess who’s sneakily beating the pack to the title of having the globe’s first 7-inch Honeycomb tablet… why, it’s none other than ViewSonic! The ViewPad 7x (1024 x 600 resolution) managed to leak out earlier this month, but now it’s fully official with Google’s Android 3.0.1 OS, HSPA+ connectivity, and a pair of cameras, one on the front and one on the back. A Tegra 2 dual-core processor plus an HDMI-out have also been included inside a featherweight 380g package. Ironically, ViewSonic’s neglected to provide a release date for this “world first” tablet, but we’ll be hitting up its booth here at Computex for some more hands-on time and making sure to collect that and every other salient detail about the ViewPad 7x.

Verizon bonanza: Droid X2, Revolution, Trophy, and Xperia Play hit Big Red today

Verizon is seriously diversifying its portfolio today with the official in-store launch of four new smartphones. Three of them roll up in Android gear, though they all have major selling points beyond Google’s software. LG’s Revolution is the sole LTE-capable handset of the bunch, bringing with it a 4.3-inch screen and pre-installed Netflix for $250. The Droid X2 undercuts it on price, at $200, but doubles the core count with its Tegra 2 processor and ramps up resolution to qHD (960 x 540). Gaming aficionados can spend the same amount on the Xperia Play from Sony Ericsson, which offers a slideout gamepad and unique PlayStation Certified status. Bringing up the rear is HTC’s well-traveled Trophy, a 3.8-inch Windows Phone that accepts it’s a little late to the party and therefore slices $50 off its asking price, with a $150 levy before the obligatory two-year contract. What say you — buy, try, or keep waiting?

NASA abandons Mars rover Spirit, chooses to remember the good times

More than a year after it first lost contact with its Mars rover Spirit, NASA has finally decided to throw in the towel. Yesterday, the agency confirmed that it will end all planned communications with the robot on May 25th, effectively ending the craft’s seven-year mission. NASA was hoping that the approaching Martian spring would allow the Spirit to recharge its solar panels and re-establish radio contact, but it now appears that the craft sustained irreparable damage last winter, when it was forced to endure brutally cold temperatures. NASA executive David Lavery, however, says the rover team will remember the Spirit more for its achievements than its slow demise:

“I think we’ll all sit around and have a sip of Guinness and reminisce about when Spirit was a wee small little rover and look back at the accomplishments and successes rover had over its entire lifetime.”

So the Spirit’s spirit will live on, but what about NASA’s mission to Mars? Well, the Opportunity is still in good health and, later this year, will be joined by the next-generation, nuclear-powered rover Curiosity, which will investigate whether or not Mars ever supported life forms. Meanwhile, NASA’s network of orbiting spacecraft will continue to passively listen for signals from the Spirit, just in case it miraculously comes back to life. Full PR after the break.

Nokia Oro is covered with 18ct gold on the outside, tinged with Symbian regret inside

Nokia has just unveiled a strange new beast of a smartphone. Internally, it’s your good old C7 — 3.5-inch AMOLED screen, 720p video recording, 8 megapixel camera, a pentaband radio, and Symbian as your zombie OS — but externally it’s taken on a lick of gold paint and a rear cover made of real leather. The price for a phone built quite so luxuriously is said to be upwards of €800 ($1,126) before taxes and subsidies and launch is expected in Q3 in select countries across Europe and Asia. Russia in particular is called out as a successful market for such “premium” phones, with Nokia’s Gabriel Speratti, General Manager for its operations in the country, explaining that:

“We have a large number of users who are looking for products with a build quality and superior materials that attest to their success and social standing. In some areas, possession of such premium products is the passport to being taken seriously.”

We have to agree, owning a phone like this will certainly have an effect on your social life, we’re just not so sure it’ll be a positive one.

Samsung Galaxy Tab 10.1 will ship with Android 3.1 on board, said to be ‘a few days away’

Do you like Android 3.1? Do you like tablets slimmer than the iPad 2? You might want to talk to Samsung in that case, because the Galaxy creator has put those two features together on its Galaxy Tab 10.1 product page and has compounded the excitement with a tweet saying the tablet is mere days away. Now, there’s a bit of conflicting information here, because Samsung’s tweet actually promises Android 3.0, but the Tab 10.1 page clearly lists the harder, better, faster, stronger Android version as the one that comes with the slate. Additionally, our conversations with Samsung at Google I/O earlier this month indicated that the June 8th launch date that we’ve been taking as gospel until recently is a little shakier now, with a slight delay possibly being caused by the desire to install the latest Honeycomb on board. So maybe the tweet’s accurate in saying the Galaxy Tab 10.1 is coming in just a few days, it just depends on your definition of “few.”

Update: Another tweet from Samsung’s US account has reaffirmed that Android 3.1 will be the OS.

Dell’s XPS 15z goes on sale in the US, shiny aluminum is yours from $999

Toshiba abandoning plans for Windows 7 tablet, Chromebook?

We were expecting Toshiba to launch its Windows 7 tablet during the second half of this year, but rumor has it that the company may be abandoning the slate altogether. DigiTimes is reporting that both the 11.6-inch slab and a forthcoming Chromebook have disappeared from Toshiba’s product launchpad, according to sources within the industry. The Chromebook will reportedly be slashed due to disappointing netbook sales in 2010, whereas the reasons behind the tablet’s cancellation remain less clear. DigiTimes suggests that Toshiba may be throwing all of its weight behind its new Honeycomb-powered Thrive slate, meaning that its Windows 7 counterpart could either be delayed even further, or simply relinquished. There’s obviously plenty of speculation swirling around, but we’ll let you know as soon as we receive more concrete reports.

Sigma SD1 starts shipping in June for $9,700, has its sights set on medium format lovers

Sigma knows that $9,700 is a lot of money to pay for, well, anything, so it’s couching the hefty price tag on its new flagship DSLR, the SD1, in the context of it competing against medium format digital cameras — whose prices don’t generally fall below five figures. Trouble is, as professionally inclined, well designed, and durably built as the SD1 may be, it still only packs a 15.3 megapixel CMOS sensor that spans 24mm x 16mm (or APS-C size). That means it’ll have to earn its stripes on the battlefield of image quality, which it’ll be ready to march onto in less than a month’s time. Sigma promises to start shipping units in early June, so if you have the cash to spare (plus a little extra to fund a suitably awesome lens), you can start building up your anticipation today. Full PR and camera specs can be found after the break.
