Mars has often been compared to deserts on Earth, and for good reason: it is pretty much a barren landscape with a lot of sand and rocks everywhere. Sometimes, the similarities can be quite striking, and the terrain in Gale crater where the Curiosity rover is roaming around is a good example. The rover is currently in a region of stunning scenery – buttes and mesas which are very reminiscent of ones on Earth. This area could easily be mistaken for the American southwest if it weren’t for the dusty, pinkish sky and complete lack of vegetation. Curiosity is now getting a close-up look at these formations, which are not only beautiful but record a long and fascinating geological history.

NASA’s InSight mission to Mars will now go ahead as planned, it was announced today. After a delay due to a vacuum leak last December, with a launch originally slated for last March, it was unclear whether the mission would still be given the green light for a later launch. But now NASA has approved a launch for spring 2018.

The Curiosity rover is continuing to travel through the ancient and eroded buttes and mesas which are part of the Murray Buttes formation. Very reminiscent of the terrain in the desert regions of the American southwest. Included are a couple new panoramas, processed by Thomas Appéré. All images are available on the mission website.

The Curiosity rover has been sending back some beautiful images of the Murray Buttes which it has now reached, near the base of Mount Sharp, on Mars. There are many buttes and mesas in this region, including in the foothills of the mountain itself. The current header graphic for the blog is also part of a new panoramic image of the buttes, processed by James Sorenson. All images are available on the mission website.

Viking remembered: Celebrating the 40th anniversary of the first search for life on Mars

July 20, 1976, will be forever remembered by space enthusiasts. On that day, Viking 1 became the first U.S. spacecraft to land on another planet – in this case, Mars (the USSR Venera 9 spacecraft landed on Venus in 1975). That lander, and Viking 2 which followed it Sept. 3, 1976, paved the way for more complex missions later on, which would begin to finally unlock some of the secrets of the mysterious Red Planet. The two Viking landers, and their counterpart orbiters, were genuine trailblazers, opening up the vast Martian landscape to robotic and human eyes for the first time.

Mars rovers update: Curiosity turns toward Mount Sharp, Opportunity finishes in Marathon Valley

NASA’s current rovers, Curiosity and Opportunity, are continuing to explore their respective regions of Mars, with new findings that are providing yet more clues as to the geological history and potential past habitability of this fascinating world. They have also both just completed significant steps in their journeys and are now entering new and exciting phases of their missions. Both missions have found yet more evidence that the Mars we see today – cold and dry – was once much wetter and potentially habitable, at least for microorganisms.

Back to the Moon? New House bill defunds NASA’s Asteroid Redirect Mission

Sending human astronauts to Mars is a dream shared by many, but there are still challenges to overcome and the question of just how to accomplish it is a subject of intense debate. Some supporters advocate sending a mission directly to Mars, while others think that returning to the Moon first, for potentially beneficial training, is the way to go. Indeed, former astronaut James Lovell, who flew on two trips to the Moon, has also called for a return to the Moon first. NASA itself has stated its desire to send a crewed mission to a nearby asteroid first, instead of the Moon, going a bit farther into space than the Moon as its idea of preparation for the much longer journey to Mars. A major problem has been that NASA has still not set a firm timetable for such a mission; it wants to go to Mars, but the steps to achieving that goal are still unclear.

Evidence from Curiosity rover shows Mars once had oxygen-rich atmosphere

Mars’ atmosphere is thin and cold, composed primarily of carbon dioxide along with other trace gases and some water vapour. Evidence has continued to mount, however, that the rarified atmosphere we see today once used to be much thicker and possibly warmer, making it potentially more life-friendly early on. Just how thick and how warm is still a subject of much debate, but there is also another interesting aspect to all of this: New evidence from the Curiosity rover has shown that the Martian atmosphere also used to have a lot more oxygen in it than it does now. Today, only very small traces of oxygen can be found, as opposed to Earth’s oxygen-rich atmosphere. So what does this mean? Could there be biological implications?

Opportunity rover moves to new target on steep slope, sees swirling dust devil

Almost, but not quite… the Opportunity rover is now driving to another area on the hillside where it is currently located, after attempting to reach a difficult rock target. The rover wasn’t quite able to get close enough to the target to conduct further studies, after driving on the steepest slope ever encountered by any rover so far, on Knudsen Ridge.

This image from the Curiosity rover on sol 1294 shows some very delicate rock formations on Naukluft Plateau, shaped by blowing Martian sand. The thin atmosphere and lower gravity also help in the formation of such spindly protrusions. Similar ones have also been seen before by the rover.
