Microscopic images of the soil taken by Opportunity revealed small spherically shaped granules. They were first seen on pictures taken on Sol 10, right after the rover drove from the lander onto martian soil. When Opportunity dug her first trench (Sol 23), pictures of the lower layers showed similar round spherules. But this time they had a ...
KOH, like NaOH, serves as a source of OH −, a highly nucleophilic anion that attacks polar bonds in both inorganic and organic materials. Aqueous KOH saponifies esters: KOH + RCOOR' → RCOOK + R'OH. When R is a long chain, the product is called a potassium soap.
The rover used its Mastcam instrument to capture the area on the 4,352 Martian day of the pioneering mission. Images of the area from NASA’s Mars Reconnaissance Orbiter had shown light-colored ...
The zodiac constellations of Mars's ecliptic are almost the same as those of Earth — after all, the two ecliptic planes only have a mutual inclination of 1.85° — but on Mars, the Sun spends 6 days in the constellation Cetus, leaving and re-entering Pisces as it does so, making a total of 14 zodiacal constellations.
New images from NASA’s Mars Reconnaissance Orbiter may show where life first began on Mars. The site on southern Mars shows massive deposits in a basin that scientists say were formed a long ...
NASA's Curiosity rover has been exploring the Gale Crater on Mars since 2012, and in that time has come up with some astounding discoveries that suggest the Red Planet was somewhat Earth-like in ...
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
Spotting Mars at opposition is easier than you might think because the planet will stand out due to its color and radiance. Instead of appearing a whitish yellow shade like the stars, it will be a ...
