In, Through, and Beyond Saturn’s Rings

Image Credit: Cassini Imaging Team, ISS, JPL, ESA, NASA

Explanation: A fourth moon is visible on the above image if you look hard enough. First — and farthest in the background — is Titan, the largest moon of Saturn and one of the larger moons in the Solar System. The dark feature across the top of this perpetually cloudy world is the north polar hood. The next most obvious moon is bright Dione, visible in the foreground, complete with craters and long ice cliffs. Jutting in from the left are several of Saturn’s expansive rings, including Saturn’s A ring featuring the dark Encke Gap. On the far right, just outside the rings, is Pandora, a moon only 80-kilometers across that helps shepherd Saturn’s F ring. The fourth moon? If you look closely in the Encke Gap you’ll find a speck that is actually Pan. Although one of Saturn’s smallest moons at 35-kilometers across, Pan is massive enough to help keep the Encke gap relatively free of ring particles.

As you’ll note in the side bar one of my favorite sites is APOD Astronomical Picture Of the Day, the above picture from Saturn is from the APOD. the single largest segment of memory on my iPad is devoted to these pictures. I understand that a human’s limited senses would not see these views but they still haunt me with their beauty and inaccesibility. Here is wonder and beauty we cannot destroy.

Have to admit I’m a mite disappointed in humanity right now…hence the mooning over moons. We have a huge amount of capability and mountains of resources at our finger tips but we seem to have lost the magic sauce of leadership. I don’t know if we (humans) are going through a phase change right now or just hitting a rough patch or perhaps we have reached Lemming Stage (too many people period and some deep programming sets us at a metaphorical run towards the nearest metaphorical cliff.) I hope it’s no LS just a rough spot in the singularity….whatever that turns out to be.

Ink Jet electronics progress

Ink-Jet Printed Graphene Electronics

Okay this brings back memories, as a young engineer I supported-oversaw ManTech R&D on ink jet printing of electronic circuits and the development of ink tech. Different time, place, technology but still cool and promising especially for the US I think the center of custom/additive manufacturing.

To get the geek juices flowing in any ManTech junkies here is the abstract:

We demonstrate ink-jet printing as a viable method for large area fabrication of graphene devices. We produce a graphene-based ink by liquid phase exfoliation of graphite in N-Methylpyrrolidone. We use it to print thin-film transistors, with mobilities up to~95cm^2V^(-1)s(-1), as well as transparent and conductive patterns, with~80 % transmittance and~30kOhm/sq sheet resistance. This paves the way to all-printed, flexible and transparent graphene devices on arbitrary substrates

This Still Trips My Sense of Wonder

New Samsung Galaxy Nexus Android/Google Phone

GPS, an accelerometer, gyroscope, digital compass, proximity and light sensors, and a barometer round out the main sensors. A 5-megapixel camera with autofocus and a single LED flash – capable of 1080p 30fps video recording – is on the back, while 1.3-megapixel camera for up to 720p video calls is on the front, above the display. A multi-color notification light hides in the Nexus’ chin.

Very good article in SlashGear online Magazine I stumbled across.

HiTech & HiCost why the AirForce can’t afford itself

A very good post on Strat Page regarding the F22 and the cost of upgrades, original program and maintenance. It concludes with these two paragraphs which I think clearly state the problem.

New technology gives a weapon, especially an aircraft, an edge in combat. But since World War II, most military technology has been developed in peacetime conditions. This means it is more than twice as expensive, as there is no wartime urgency to overcome bureaucratic inertia (and emphasis on covering your ass, which is very time consuming and expensive) and hesitation (because you don’t have a war going on to settle disputes over what will work best). Developing this new technology takes longer in peacetime, which also raises the cost, and fewer units of a new weapon are produced (driving up the amount of development cost each weapon will have to carry.) If several hundred B-2s were produced under wartime conditions, each aircraft would have probably cost $200 million, or less. In other words, a tenth of what it actually cost. Same deal with the mythical $35 million F-22, or any other high tech weapon.

Other nations have adapted more effectively to peacetime development conditions. But the United States has the largest amount of peacetime military research and development, and this has created a unique military/industry/media/political atmosphere that drives costs up to the point where voters, politicians and the media will no longer support them.
