NASA's Laser Pulse ChemCam Examines What Stuff Is Made Of By Zapping Lasers At Them

NASA's high energy laser is going to be mounted on the next Mars rover. Its Pew Pew Ness is going to vaporize things with a laser to find out what they are made of.
The laser-induced breakdown spectroscopy system (LIBS), called ChemCam, will launch next year. It sends an average of three 10-watt, five-nanosecond laser pulses per second and is perfect for collecting and analyzing rock samples:
The laser shots vaporize a crater less than a millimeter across, turning its molecules into a 14,000-degree plasma. The atoms are shorn of their electrons, but as the plasma ball cools down, they return to a more normal state. The electrons drop into their orbits around the nucleus and as they do so, the little plasma ball emits light...
The specific color of the light tells scientists exactly what element they are looking at if they pass it through a spectrometer, which can precisely measure the wavelength of light.
Human waste will never be the same again. Why? Because U.K has started using our poop to run its 'Bio-Bus' which has now taken to the streets. The bus runs on biomethane gas which is produced from treated human waste, and unused food. Don't worry. They have those impurities and bad odors removed, so you don't have to 'experience' the smell.

Apple already had an Apple Watch before launching their current version - the one that's going to sync with your iPhone and do all sorts of stuff. The original on the other hand, doesn't need any apps. Check it out below: Read more
Using a company with a good reputation to offer managed services can be a beneficial way to free up resources and reduce costs - your own staff will have more time to spend on their strategic ICT work within your business and instead of having to recruit and train more on-site employees of your own to handle routine maintenance, you can rely on the managed services provider to take care Read more
