With so much attention now on the rovers and spacecraft at Mars, Saturn, Ceres, comet 67P/Churyumov-Gerasimenko, and, soon, Pluto, it may seem like Earth’s closest planetary neighbor Venus has been forgotten again. But no, Venus is still very much on the minds of researchers who are busy developing a concept airplane which could cruise for years in the hellish planet’s atmosphere.

Exploring an alien sea: NASA designs submarine to send to Titan

Who wouldn’t want to go explore an alien sea? It seems that NASA would certainly like to, and the agency has unveiled a new submarine design to hopefully do just that one day. The submarine would be sent to Saturn’s largest moon, Titan, to dive into one of the large liquid methane seas on the moon’s frigid surface; such a mission idea may sound like science fiction, but it’s not, and would be the first ever to explore a sea on another world which is both Earth-like in some ways, yet utterly alien in others.

Addendum: press release is now available here.

The images being taken by the Curiosity rover on Mars have been amazing enough so far, but with one thing in common – they are all daytime images. Now, though, Curiosity has taken its first nighttime photos! These initial images were taken a couple of days ago, on sol 165. This is also the location where Curiosity will soon do its first drilling.

The next generation of robotic space explorers – powered by bacteria!

As technology advances, a lot of the gadgets and other things we use keep getting smaller, lighter and thinner. Now that trend may soon be taken to another extreme – small robotic space explorers which in turn use a miniscule power source – bacteria
