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.

Using lasers to communicate at planetary distances is something that may sound like sci-fi, but it is a real technology being developed by NASA as a means of communicating with spacecraft faster and more efficiently than can be done now.

There is new evidence from the Mars Reconnaissance Orbiter spacecraft for an ancient Martian lake that may have been an ideal habitable environment, it was announced yesterday.

The Curiosity rover continues making progress as it travels across the terrain in Gale crater, getting ever closer to its primary target, Mount Sharp. This new photo from the Mars Reconnaissance Orbiter, taken on January 2, 2013, shows the rover at its current position, with its tracks clearly seen behind it.

The Curiosity rover is almost ready to drill into its first rock in a matter of days, and in the meantime has found more evidence that this region in Gale crater was once much wetter than it is now.

The new year has barely begun, and already it has been a good one for exoplanets. In a previous update, it was reported that the Kepler space telescope has added hundreds of exoplanet candidates to its rapidly growing list. That is exciting enough, but another new study now, similar to other ones, estimates that there are billions of other planets in our galaxy alone.

Apart from being composed of liquid methane instead of water, the rivers, lakes and seas of Saturn’s moon Titan are amazingly similar in appearance to those on Earth. The hydrological cycle is also very similar, with Titanian rain replenishing them.

As well as close-up images of the various fascinating features of the terrain, the Curiosity rover also continues to send back beautiful views of the landscape itself in Gale crater. One of the latest is this view from Yellowknife Bay on sol 141, where Curiosity is still doing its current investigations. Another wonderful panorama from Damien Bouic. The original largest version is here. All of Damien’s images, stitched together from the original Curiosity images, are here (the web site is in French).
