As Seen on @CBSThisMorning, which is posting some of our images each morning this week: Making Tracks on Mars. Our Curiosity rover is driving toward Mount Sharp on Mars. Using the front and rear hazard cameras (“hazcams”) we see the 3-kilometer-tall Mount Sharp looming ahead, and fresh rover tracks left behind. Since landing, Curiosity has driven 5 miles (8 kilometers) stopping to do science along the way. One of Curiosity’s first major findings after landing on the Red Planet in August 2012 was an ancient riverbed at its landing site. Nearby, at an area known as Yellowknife Bay, the mission met its main goal of determining whether the Martian Gale Crater ever was habitable for simple life forms. The answer, a historic “yes,” came from two mudstone slabs that the rover sampled with its drill. Analysis of these samples revealed the site was once a lakebed with mild water, the essential elemental ingredients for life, and a type of chemical energy source used by some microbes on Earth. If Mars had living organisms, this would have been a good home for them.
Rovers are gathering valuable scientific information and helping pave the #PathToMars as part of our #NextGiantLeap — sending astronauts to the Red Planet.

El texto original, de Joseph Conrad, con harto pie de página explicativo e interactivo.
La estupidez de las gallinas.
La facilidad con la que pueden ser hipnotizadas.
El mito de Prometeo
se regenera en la mente
del cirujano que siente
cómo se rompe el tejido
del hígado acometido
por el cáncer recurrente.
Sajado el lóbulo clásico,
en la noche del paciente
–que convalece inconsciente–
se recupera lo urdido
en el lienzo repetido
del pasado en el presente.
'Uno teme todo el tiempo cuando escribe’, nos dijo Jeremías Gamboa. El temor a equivocarse, o a arriesgarse, o a que nadie le guste lo que escribes. El proceso de escribir tiene etapas, y demanda tiempo, sacrificio y dedicación. Pero eso no fue un obstáculo insuperable para escribir su primer libro de cuentos, Punto de Fuga, ni las 196 mil palabras de su nueva novela.
Grande, grande, grande…
I’m beginning to see the light
#Repost from @nasa —- NASA’s Curiosity Mars rover has imaged the planet Mercury passing in front of the sun, visible as a faint darkening that moves across the face of the sun.
This is the first transit of the sun by a planet observed from any planet other than Earth, and also the first imaging of Mercury from Mars. Mercury fills only about one-sixth of one pixel as seen from such great distance, so the darkening does not have a distinct shape, but its position follows Mercury’s expected path based on orbital calculations.
The observations were made on June 3, 2014, from Curiosity’s position inside Gale Crater on Mars. In addition to showing the Mercury transit, the same Mastcam frames show two sunspots approximately the size of Earth. The sunspots move only at the pace of the sun’s rotation, much slower than the movement of Mercury.
Many viewers on Earth observed a Venus transit in June 2012, the last visible from Earth this century. The next Mercury transit visible from Earth will be May 9, 2016. Mercury and Venus transits are visible more often from Mars than from Earth, and Mars also offers a vantage point for seeing Earth transits. The next of each type visible from Mars will be Mercury in April 2015, Venus in August 2030 and Earth in November 2084.
This animated blink comparison shows five versions of observations that NASA’s Curiosity made about one hour apart while Mercury was passing in front of the sun on June 3, 2014. Two sunspots, each about the diameter of Earth, also appear, moving much less than Mercury during the hour.
