A collaborator updated one of my graphics to reflect the Philae landing on 67C-G.  Enjoy!

Awww! Together again after all these years...
Life is too short to hold a grudge

Score another one for NASA tech transfer: MSL technology has been adapted to help Pacific Gas & Electric find methane leaks. The specific technology in question is the tunable laser spectrometer, part of the SAM instrument that seeks organics on the red planet. So not only is the SAM TLS telling us about life on other worlds, it also keeps your house from blowing up.

This is great! (Note the red guy is a tad delayed.  That's probably why they get deaded.)

Magic Sand or Hydrophobic Sand

Magic sand, Moon Sand, Mars Sand, Space Sand, Sand or Aqua Sand is a toy made from sand coated with a hydrophobic compound. The presence of this hydrophobic compound causes the grains of sand to adhere to one another and form cylinders (to minimize surface area) when exposed to water. As soon as the sand is taken out of water, it is completely dry and flows freely.

These properties are achieved by covering ordinary beach sand, which contains tiny particles of pure silica, and exposing them to vapors of trimethylsilanol (, an organosilicon compound. Upon exposure, the trimethylsilane compound bonds to the silica particles while forming water. The exteriors of the sand grains are thus coated with hydrophobic groups.

Magic sand was originally developed to trap ocean oil spills near the shore. This would be done by sprinkling Magic sand on floating petroleum, which would then mix with the oil and make it heavy enough to sink. However, due to the expense of production, it is not being used for this purpose. It has also been tested by utility companies in the Arctic areas as a foundation for junction boxes, as it never freezes. It can be also used as an aerating medium for potted plants.

Magic sand is made in blue, green, or red in colors but appears silvery in water because of a layer of air that forms around the sand, making it unable to get wet.

Earliest reference to waterproof sand can be found in a 1915 book called The Boy Mechanic Book 2 put out by Popular Mechanics. The Boy Mechanic states waterproof sand was invented by East Indian magicians. The sand was made by mixing heated sand with melted wax. The wax would repel the water when the sand was exposed to water.

1st Official Trailer: Spring 2014 IMAX Film "In Saturn's Rings"
Massive +NASA Photos of Earth, Mars, Saturn & Beyond! Transformed into Epic IMAX Film! | Highly Recommended!
To watch this awe-inspiring film trailer in 1080p HD or 4K Ultra HD, choose "original" under YouTube quality settings (you need a fast computer and a 4K monitor to view it full resolution) at:

Official "In Saturn's Rings" Film Website:

Director Stephen van Vuuren used more than a million photographs and numerous film techniques to create the effect of flying through space around Saturn and among its rings!
The film is dedicated to Stanley Kubrick & Carl Sagan.

"This film was 100% created using only flat 2D photographs (often hundreds or thousands per frame) stitched together for massive hundred megapixel+ resolutions that are scaled and zoomed using techniques developed by the filmmaker, based on Ken Burns and 2.5D photo animation processes!

A computer is actually not even required to do this - it could all be done exactly using photoanimation techniques from 100 years ago!:

No 3D models, texture mapping, 3D CGI, camera projection, cloning or painting or any other VFX techniques are used - every pixel is what was captured in the photograph. The photographs are processed as minimally as possible - much less than your average Instagram photo."

While listening to the Adagio for Strings by Samuel Barber one day in 2006, Director van Vuuren conceived the idea of creating moving images of Saturn using a pan and scan 3-D effect he had seen in a 2002 documentary called The Kid Stays in the Picture. The technique involves creating a 3-D perspective using still photographs.[3] (The Adagio for Strings would later become part of the soundtrack for In Saturn's Rings.)

Mind officially blown.
Once you figure this out it'll blow your mind...

"The lines over the circles are color coded. Notice the single red line and 3 blue lines representing "13" grouped together while the single green and 2 black lines take their own group. [Simply] draw your first group of lines in one direction then your second group of lines going over the first, count the groups of intersections and there's your answer."
