Curiosity has reached another area of interesting terrain: rows of layered curvy rocks.

The science team has been hunting for tasty rock outcrops suitable for the first drilling campaign since she departed the dried out lakebed at Yellowknife Bay in July 2013 and began her epic trek across the floor of Gale Crater towards the base of Mount Sharp. With each passing Sol, or Martian day, Mount Sharp looms larger and larger and the historical layers with deposits of hydrated minerals potentially indicative of an alien habitable zone come ever clearer into focus.

The panoramas are quite spectacular as the rover continues its journey toward Mt Sharp.

Before and after images from Mars Reconnaissance Orbiter have discovered the formation of a new gully on Mars sometime between November 2010 and May 2013.

Before and after images from Mars Reconnaissance Orbiter have discovered the formation of a new gully on Mars sometime between November 2010 and May 2013.

The winding gully seems to have poured out from an existing ribbon channel in a crater in Mars’ Terra Sirenum region. The leading hypothesis on how the gully formed is that debris flowed downslope from an alcove and eroded a new channel. Though it looks water-carved, the gully is much more likely to have been formed when carbon dioxide frost accumulated on the slope and grew heavy enough to avalanche down and drag material down with it.

The Obama administration budget proposal for NASA includes shutting down Opportunity in 2015.

Penny wise pound foolish: The Obama administration budget proposal for NASA included shutting down Opportunity in 2015.

This is very stupid. It costs about a billion dollars to build a rover and get it to Mars. And that’s assuming everything works. Opportunity is already there and functioning flawlessly at a fraction of that cost. Rather than cutting Opportunity, NASA should consider cutting the new rover mission so that the money could be used for other planetary exploration, such as a mission to Titan.

The IAU has issued a press release condemning the public’s naming of Martian craters as initiated by the private company Uwingu.

My heart bleeds: The IAU has issued a press release condemning the public’s naming of Martian craters as initiated by the private company Uwingu.

This war over the right to name features on other planets is mostly a tempest in a teapot, as the actual names will finally be decided by the people who end up living there. Nonetheless, I really like how Uwingu is pushing the IAU’s buttons, as that organization’s self-righteous insistence that it has the power to name everything in space, from craters to the smallest boulders, has for years struck me as pompous and wrong.

Despite IAU disapproval, the space company Uwingu has announced another private commercial naming project for the craters of Mars.

12:54 am

The war of space names continues: Despite the disapproval of the International Astronomical Union (IAU), the space company Uwingu has announced another private commercial naming project for the craters of Mars.

Starting today (Feb. 26), anybody with an Internet connection and a few dollars to spare can give a moniker to one of the Red Planet’s 500,000 or so unnamed craters, as part of a mapping project run by the space-funding company Uwingu. “This is the first people’s map of Mars, where anybody can play,” said Uwingu CEO Alan Stern, a former NASA science chief who also heads the space agency’s New Horizons mission to Pluto. “It’s a very social thing.”

Sounds fun, and a clever way for this company to raise capital. Whether these names stick is an entirely different thing. Uwingu has as much right to assign names to objects as the IAU, but so far the IAU’s fake authority in this matter carries more weight.

A ruling by “a fatwa committee” in the United Arab Emirates now forbids Muslims from going on a one way mission to Mars.

A ruling by “a fatwa committee” in the United Arab Emirates now forbids Muslims from going on a one way mission to Mars.

“Such a one-way journey poses a real risk to life, and that can never be justified in Islam,” the committee said. “There is a possibility that an individual who travels to planet Mars may not be able to remain alive there, and is more vulnerable to death.” Whoever opts for this “hazardous trip”, the committee said, is likely to perish for no “righteous reason”, and thus will be liable to a “punishment similar to that of suicide in the Hereafter”.

Suicide and martyrdom in the name of Islam, however, is perfectly all right.

Orbital images from Mars Reconnaissance Orbiter have confirmed that the mysterious rock that appeared near Opportunity was not ejecta from a nearby meteorite impact.

2:29 pm

Orbital images from Mars Reconnaissance Orbiter have confirmed that the mysterious rock that appeared near Opportunity was not ejecta from a nearby meteorite impact.

The scientists theorized that there was a very remote chance that a nearby impact has thrown the rock into place, but the images show nothing nearby. Moreover, if there had been an impact we probably would have seen more rocks raining down all around. The images are further confirmation that the rock was kicked up by the rover itself as it rolled along.

Mars Reconnaissance Orbiter spots a new crater on Mars.

Mars Reconnaissance Orbiter spots a new crater on Mars.

The scar appeared at some time between imaging of this location by the orbiter’s Context Camera in July 2010 and again in May 2012. Based on apparent changes between those before-and-after images at lower resolution, researchers used HiRISE to acquire this new image on Nov. 19, 2013. The impact that excavated this crater threw some material as far as 9.3 miles (15 kilometers).

In celebration of the tenth anniversary of Opportunity’s landing on Mars, the journal Science publishes a special section of the newest findings from Mars.

In celebration of the tenth anniversary of Opportunity’s landing on Mars, the journal Science has published a special section of the newest findings from Mars.

The main conclusion of all this research is that Mars was once potentially habitable, though there is no evidence so far to show that anything actually inhabited it. The data obtained however is now giving scientists clues on the best places to look for the remains of that ancient life, should it exist.

A donut-sized rock suddenly appears in front of the Mars rover Opportunity.

A donut-sized rock suddenly appears in front of the Mars rover Opportunity.

NASA announced the discovery of the rock at an event at Caltech in Pasadena this past Thursday night, dubbing the rock “Pinnacle Island.” “It’s about the size of a jelly doughnut,” NASA Mars Exploration Rover lead scientist Steve Squyres told Discovery News. “It was a total surprise, we were like ‘wait a second, that wasn’t there before, it can’t be right. Oh my god! It wasn’t there before!’ We were absolutely startled.”

Mars One narrows its applicant pool of would-be Martian colonists from 200,000 to just over a 1000.

People started applying for a voyage to the red planet in April 2013 through Mars One, a Netherlands-based private venture that wants to land humans there by 2025. By the time the company stopped taking applications, more than 200,000 people had submitted one. Today, Mars One announced that it’s made a short(er) list of 1,058 applicants.

These are individuals willing to make a one way trip.

Mars Express will do an extremely close flyby of the martian moon Phobos on December 29.

Mars Express will do an extremely close flyby of the martian moon Phobos on December 29.

Late this month, ESA’s Mars Express will make the closest flyby yet of the Red Planet’s largest moon Phobos, skimming past at only 45 km [28 miles] above its surface. The flyby on 29 December will be so close and fast that Mars Express will not be able to take any images, but instead it will yield the most accurate details yet of the moon’s gravitational field and, in turn, provide new details of its internal structure.

It seems Curiosity’s wheels are wearing out faster than expected and engineers want to know why.

It seems Curiosity’s wheels are wearing out faster than expected and engineers want to know why.

The increasedwear recently appears to be because the rover was traveling over rougher terrain. Nonetheless, JPL engineers are going to monitor the rover’s travel and wheel damage more closely in order to gauge that wear better for future travel.

China outlines the plans for its next two unmanned lunar probes, with the second targeted as a 2017 sample return mission.

China outlines its plans for its next two unmanned lunar probes, with the second targeted as a 2017 sample return mission.

Key quote:

The new mission planned for 2017 would mark the third and final phase of China’s robotic lunar exploration program and pave the way for possibly landing an astronaut on the moon after 2020.

As I mentioned last night, the soft landing on Saturday demonstrated they are developing the technology to land a manned vehicle safely on the Moon. To return samples safely would demonstrate they are developing the technology to return that manned vehicle safely as well.

Update: Yutu did not land anywhere near its planned landing location.

China had originally publicized a location in the Sinus Iridum (Bay of Rainbows) — a level area thoroughly surveyed by a previous Chinese mission — as the landing spot. Local media even stated that Chang’e 3 landed there. But Chinese scientists have since confirmed that the spacecraft landed slightly to the east, in the northern part of Mare Imbrium (Sea of Rains).

It is unclear whether this was a late change or the result of a technical problem.

India’s Mangalyaan Mars probe successfully completed its first midcourse correction maneuver today.

India’s Mangalyaan Mars probe successfully completed its first midcourse correction maneuver today.

As with the images the probe took of Earth, the success of this maneuver demonstrates the ability of the probe’s engineers to control, operate, and precisely point the spacecraft’s engine. It also proves that engine works as designed.

Here’s an interesting cultural tidbit: Of the 200,000 people who have applied to Mars One (see my previous post below) to go on its proposed one-way mission to Mars, India has the second most applicants after the U.S.

Mars One applicants come from over 140 countries; the largest numbers are from the US (24 per cent), India (10 per cent), China (6 per cent), Brazil (5 per cent), UK, Canada, Russia and Mexico (4 per cent), Philippines, Spain, Colombia and Argentina (2 per cent), and Australia, France, Turkey, Chile, Ukraine, Peru, Germany, Italy and Poland (1 per cent).

A private unmanned mission to Mars by 2018?

A private unmanned mission to Mars by 2018?

Dutch entrepreneur Bas Lansdorp, Mars One founder and CEO, told reporters the foundation has signed contracts with two major aerospace firms, Lockheed Martin and Surrey Satellite Technology, to develop mission concept studies, a first step toward eventual construction and launch.

The lander will be based on the design of the 2007 Phoenix Mars lander that Lockheed Martin developed for NASA. The communications satellite — the first such “geostationary” comsat in orbit around the red planet — will incorporate technologies developed by Surrey and used in a variety of operational spacecraft.

Mission concept studies are of course essential before you begin construction, but they are also a far cry from actual construction. I’ve seen literally hundreds of similar concept studies about someone’s big space plans with no subsequent follow up. Thus, I will only begin to take Mars One serious when they actually start cutting metal.
