Para los momentos de asueto y en los que tengáis tiempo para haceros algunas preguntas, os recomiendo visitéis la web de la NASA.

Lo más interesante ahora mismo es ir viendo día a día las fotos que la Sonda Phoenix nos manda desde Marte.  A otros niveles de curiosidad blogera, también es merecedor de pérdida de tiempo  la sección de Blogs que los mismos integrantes del organismo espacial mantienen. That’s science.

This image, released on America’s Memorial Day, May 26, 2008, shows the American flag and a mini-DVD on the Phoenix’s deck, which is about 3 feet above the Martian surface. The mini-DVD from the Planetary Society contains a message to future Martian explorers, science fiction stories and art inspired by the Red Planet, and the names of more than a quarter million Earthlings.

Mars, a cold desert planet with no liquid water on its surface, has water ice that lurks just below ground level in its arctic region. Discoveries made by the Mars Odyssey Orbiter in 2002 show large amounts of subsurface water ice in the northern arctic plain. Phoenix will use its robotic arm to dig through the protective top soil layer to the water ice below and ultimately, to bring both soil and water ice to the lander platform for sophisticated scientific analysis.

Cassini – Saturno y sus lunas

Las imágenes que nos trae la sonda Cassini enviada por la Nasa en los alrededores de Saturno y sus lunas son fantásticas.

Moon crossing Saturn. The moon Rhea passed in front of Saturn, as seen by NASA’s Cassini spacecraft. Cassini took the photograph March 21, 2006 at a distance of about 137,000 miles from Rhea. NASA announced that it is extending Cassini’s mission by two years. The $160 million extension will lead to 60 more orbits around Saturn, allowing Cassini to take additional looks at some of the intriguing moons, including smog-enshrouded Titan and Enceladus, which is shooting out a geyser of water ice and vapor and may have liquid water under its surface.
