"This is a close-up view of the "spectrometer-on-a-chip" technology that could dramatically reduce the size of spectrometers in the future. (Credit: NASA Goddard/Chris Gunn) - The Composite Infrared Spectrometer (CIRS) is big. It's powerful and it discovered, among other things, that Saturn's mysterious moon Enceladus was one of the very few worlds in the solar system that radiated several gigawatts of heat into space, primarily along prominent fractures dubbed "tiger stripes." If a team of technologists at NASA's Goddard Space Flight Center in Greenbelt, Md., succeeds, however, scientists in the future won't observe these far-flung worlds with instruments the size of dishwashers. Rather, they will make their discoveries with dramatically smaller, more efficient models whose critical components fit onto a silicon wafer and do not require moving parts to operate -- unlike the breadbox-size components found inside the Goddard-developed CIRS, which flew on the flagship Cassini-Huygens mission to Saturn. "The Holy Grail is reducing the number of moving parts, which will allow us to build lighter, smaller instruments," said team member John Allen. "The smaller the device, the better. That's where the power of our effort really begins to take off." More

Mars, Everest, and Tricorders

Ocean Optics Spectrometers Land Safely on Mars

"Three Ocean Optics instruments have completed their eight month journey to Mars to study soil composition as part of the ChemCam mission. The company's modular Jaz spectrometer scaled Mt. Everest with a team that included NASA astronaut Scott Parazynski to measure solar irradiance at extreme altitude."

Using a Tricorder on Mount Everest

"If you've ever seen a Starfleet away team beaming down to a new planet, you know that the first thing they do is whip out their tricorder and scan everything. Many of NASA's astrobiologists want one. Well, Scott and I had one at Everest."

Keith's note: I carried this cool device up to Everest Base Camp and then Scott carried it up the mountain. Its not unusual for people to trek into Everest with the latest high tech gear on display but every time I pulled this thing out people stopped to watch me go through my procedure. I took this promo photo of Scott using the Jaz unit while we were standing next to our tents at Everest Base Camp. An instant later we heard a loud noise coming from the icefall. An instant later I switched my camera from still to video and shot this video. This was one of the largest avalanches in recent seasons. Had I not been taking the PR shot of Scott and the Jaz unit I'd have missed most of this avalanche.

Another Tricorder Mod For the iPhone

Researchers Transform iPhone Into High-quality Medical Imaging Device, Optical Society of America

"In a feat of technology tweaking that would rival MacGyver, a team of researchers from the University of California, Davis has transformed everyday iPhones into medical-quality imaging and chemical detection devices. With materials that cost about as much as a typical app, the decked-out smartphones are able to use their heightened senses to perform detailed microscopy and spectroscopy."
