Watch 30 Years of the Space Shuttle In One Single Launch [Video]

Watch 30 Years of the Space Shuttle In One Single LaunchThe end. Today it's all over. Three decades of the Space Shuttle, with its many amazing successes and two horrible failures, are gone forever. This video shows those thirty years in one single launch.

Click video to enlarge.

The space shuttle was the most complex machine ever created. Even with all its faults, it was a mighty beast. Combined, the shuttles travelled 513.7 million miles (826.7 million km) in 135 missions. It's an staggering number—we could have visited Jupiter!

As a spacenerd who never saw Saturn V roaring up to the skies, I couldn't imagine a more amazing display of power and engineering prowess more amazing than the launch of the Space Shuttle. Strapped to 1.6 million pounds of liquid fuel and two solid rocket boosters pushing 5,600,000 pounds-force of liftoff thrust, it was a thing of beauty that we will never see again.

For someone who saw the original launch of Columbia as a kid, I'm finding it hard to believe that everything is over just three decades later. If I feel gutted today, I can't even begin to imagine how people working in the program must feel. Still, I'm hopeful that things will get even more exciting in the coming years, hopefully with a mission to Mars and other planets. Until then, I'll watch this video to remind me of the genius of human engineering and the American space program.

Godspeed Columbia, Challenger, Discovery, Atlantis, and Endeavour. And thanks for all the fish.

The 13-Inch MBA Burns the Fastest 2010 MacBook Pro [Factoid]

The 13-Inch MBA Burns the Fastest 2010 MacBook ProHoly crud. While it's just a benchmark test and those don't accurately reflect yadda yadda yadda YOU GUYS. The 1.7GHz Core i5 13-inch MBA just blew the door off of last year's 2.67GHz Core i7 17-inch MacBook Pro on GeekBench. And did more than twice as well as last year's tricked 13-inch Air. That is bonkers.

At this point—unless you work in the optical drive industry—why would the 90% of us who don't need professional-grade computing ever choose a Pro over an Air? [Laptop Mag via ElectricPig]

Nasa's Official Android App Makes Me CryDownloading the new-and-official Nasa app on my Android phone today was a bittersweet experience, what with Atlantis—and NASA's—last journey ending today. There're heaps of features considering it's free—live Nasa TV, images, future mission details *sniffles* and sighting opportunities.

Judging by the information supplied to me, the next opportunity I have to spy on the ISS is the 28th of July, at 4.21am GMT. I'd rather just catch up on Nasa videos, or take a look at their integrated Twitter stream, if I'm honest. Here's the full list of features:

- Thousands of images from NASA IOTD, APOD and NASAImages.org
- On demand NASA Videos from around the agency
- Current NASA Mission Information
- Launch Information & Countdown clocks
- Current Visible Passes for the International Space Station (ISS)
- ISS and Earth Orbiting Satellite Tracker
- NASA Twitter Feeds from around the agency
- News and Features from the NASA topic areas
- Facebook® Connect and Integrated Twitter™ client for easy sharing
- Live Streaming of NASA TV
- NASA TV and What's On Your TV schedules
- Map and links to all of the NASA centers
- Featured content section

Out now for iOS and now Android, it's a free download. [Android Market via The Telegraph]

Researchers use graphene to draw energy from flowing water, self-powered micro-robots to follow?

Source: http://www.engadget.com/2011/07/21/researchers-use-graphene-to-draw-energy-from-flowing-water-self/

What can't graphene do? The wonder material's been at the heart of a stunning number of technological breakthroughs of late, and now it's adding oil exploration to its long list of achievements. A team of researchers at Rensselaer Polytechnic Institute have discovered that the flow of good old H2O over a sheet of graphene can generate enough electricity to power "tiny sensors" used in tracking down oil deposits. The gang, led by professor Nikhil Koratkar, was able to suck 85 nanowatts of power out of a slab of graphene measuring .03 by .015 millimeters. The little sensors the researchers speak of are pumped into potential oil wells via a stream of water, and are then put to work sniffing out hydrocarbons indicative of hidden pockets of oil and natural gas. Of course, that doesn't have a whole lot of practical application for your average gadget consumer, but Koraktar sees a future filled with tiny water-powered robots and micro-submarines -- we can dig it.

5 Best Alternatives to Apple's New Product Lineup [Toolkit]

5 Best Alternatives to Apple's New Product LineupShocking as this news may be, not everybody uses a Mac (*raises hand*). For those of us not drinking the Cupertino Koolaid, here are 5 solid alternatives to the new products from today's Apple announcement.

5 Best Alternatives to Apple's New Product Lineup

MacBook Air = Samsung Series 9


The Series 9 is like the MBA, just slightly bigger. Unfortunately that includes the price as well. For $1199— what you'd pay for a 2.38 lb., 11.6" MBA with 4GB of memory and 128GB SSD—you get a 2.31 lb. 11.6" laptop with 2GB of memory and only a 64GB SSD. The other smaller thing about Series 9? Its processing speed: 1.33GHz vs the MBA's 1.6GHz. $1200

MacBook = Toshiba Portege R835-P70

In terms of performance for price, the R835 gives you more value. It has a 2.3GHz processor, 4GB of RAM, and 640GB HD, double the available RAM and triple the available standard HD in the last iteration of the MB (before, you know, Apple killed it and all) for $65 less. $835

5 Best Alternatives to Apple's New Product Lineup

Mac Mini = Dell Inspiron Zino HD

Sure the Mini isn't technically designed as an HTPC but some of its best work is done as a home theater-serving hockey puck. The Dell Zino does essentially the same job, albeit as two stacked hockey pucks. It's got the same basic stats as the Mini, 2.3GHz processor and 2GB of RAM, but the Zino is double the height in order to make room for the tray-loading CD/DVD/Blu-Ray combo drive. On the other hand, at $300, the Zino is half the Mini's height in money. $300

Thunderbolt = USB 3.0

Thunderbolt has a data transfer speed of 10Gb/s. USB 3.0 has a maximum data transfer speed of 5 Gb/s. It's half but available on things that don't start with Mac. What more do you want? (image courtesy of Maximum PC) $Depends on what it's attached to

Thunderbolt Display = Dell UltraSharp U2711

The Thunderbolt display's 27" viewing area with 2560-by-1440 LED-backlit resolution and ability to daisy-chain peripherals is just brilliant. But if you don't really give a shit about stringing your hard drives to your monitors (or you only have one of each and are already connected through your computer) then you'll want to check out the Dell UltraSharp U2711. It has a 2560 x 1440 resolution 27" display with 80,000-to-1 contrast ratio. And it's $100 less. $900
