Curiosity rover captures incredible snap of Martian moon moving across the sun creating a mini-eclipse

“Nasa’s Curiosity rover continues to impress – sending back more snaps of Mars eclipses and a particular pyramid shaped rock.

A new extraordinary photograph of one of the Red Planet’s two moons as it passes across the sun has emerged.

The photo shows Deimos, Mars’ smaller moon, moving over the sun to create a partial eclipse on Monday.

The first pictures of the Martian mini-eclipses were revealed last weekend when Phobos, the larger of the two moons, just jutted into Mars’s view of the sun.

In that picture Phobos appears to be taking a ‘bite’ out of the sun whereas in the latest photo of Deimos, the smaller moon darkens the sun much more clearly.

Phobos measures 14 miles in width while Deimos has a width of just eight miles but the larger moon seems bigger when seen from Mars because it orbits so much closer.

Phobos orbits 5,800 miles versus 14,580 miles for Deimos, reported NBC.

Phobos and Deimos are closer to Mars than our moon is to Earth, so they shoot across the sky relatively quickly. Phobos takes less than eight hours to circle Mars. Deimos takes about 30 hours to make the trip.

And while Mars may be a little further away from the sun than we are here on Earth, it would still be damaging to look directly into its light from the Red Planet. If Curiosity pointed its regular lens straight at the sun, it could have been destroyed.

So instead the rover used a neutral density filter, cutting down the sun’s intensity by a factor of 1,000, according to NBC News.

Besides the mini-eclipses, Curiosity is concentrating on an intriguing pyramid shaped rock the size of a football.

The rock carries the honour of being the first to be examined by rover’s robotic arm.

It lies about halfway from the rover’s landing site, Bradbury Landing, to a location called Glenelg.

The team plans to touch the rock with a spectrometer to determine its elemental composition and use an arm-mounted camera to take close-up photographs.

Both the arm-mounted Alpha Particle X-Ray Spectrometer and the mast-mounted, laser-zapping Chemistry and Camera Instrument will be used for identifying elements in the rock.

Nasa hopes this will give them a new insight into the structure of the red planet, and also allow cross-checking of the two instruments.

The rock has been named ‘Jake Matijevic’ after a Nasa employee who recently passed away.

Also among the new photos sent back were snaps of Curiosity itself – a view of its U.S. flag medallion, as well as the traditional presidential plaque.”

Mars’ Heartless Animal Experiments

Not one of Mars’ experiments on animals is required by law. Even so, Mars has paid experimenters to kill untold numbers of animals in tests:


  • Mars recently funded an experiment on rats at the University of California, San Francisco, to determine the effect of chocolate ingredients on the animals’ blood vessels, even though the experimenter admitted that studies have already been done using humans. Experimenters force-fed the rats by shoving plastic tubes down their throats and then cut open the rats’ legs to expose an artery, which was clamped shut to block blood flow. After the experiment, the animals were killed.
  • Mars funded a deadly experiment on mice that was published in a 2007 issue of the Journal of Neuroscience in which mice were fed flavanols (phytochemicals that are found in chocolate) and forced to swim in a pool of water mixed with white paint to hide a submerged platform, which the mice had to find in order to avoid drowning, only to be killed and dissected later on.
  • In one experiment supported by Mars and conducted by the current Mars, Inc., endowed chair in developmental nutrition at the University of California, Davis, rats were fed cocoa and anesthesized with carbon dioxide so that blood could be collected by a needle injected directly into the heart—a procedure criticized by U.S. Department of Agriculture researcher Dr. William T. Golde, who notes: “This is not a simple method. … Missing the heart or passing the needle completely through the heart could lead to undetected internal bleeding or other complications.”
  • Mars supported a cruel experiment to learn how a chocolate ingredient called PQQ affects metabolism by cramming baby mice into 200-milliliter Plexiglas metabolic chambers—around half the size of a 12-ounce soda can—and then submerging the chamber for nearly five hours in a chilled water bath, inducing labored breathing in the distressed mice. Experimenters then shoved tubes down the mice’s throats every day for 10 days to force-feed them the PQQ, after which they were killed and cut up for analysis.
  • Mars funded a test in which experimenters forced rabbits to eat a high-cholesterol diet with varying amounts of cocoa, then cut out and examined tissue from the rabbits’ primary blood vessel to the heart to determine the effect of cocoa on rabbits’ muscle tissue.
  • Mars supported a test in which experimenters attached plastic tubes to arteries in guinea pigs’ necks and injected cocoa ingredients into their jugular veins to examine the effect of cocoa ingredients on their blood pressure.

What the hell… WHY?! What is wrong with this world?
