NASA’s Curiosity Captures Lovely Views of a Altering Mars Panorama – NASA Mars Exploration

Putting rock formations documented by the rover present proof of a drought local weather within the Purple Planet’s historical previous.

Over the previous 12 months, NASA’s Curiosity Mars rover has traveled by a transition zone from a clayey area to at least one full of a salt mineral referred to as sulfate. Whereas the science crew has focused the clairvoyant area and the sulfate-laden one for proof every can present about Mars’ watery previous, the transition zone additionally seems to be scientifically fascinating. In actual fact, this transition might present the document of a serious shift in Mars’ local weather billions of years in the past that scientists are solely starting to grasp.

The clay minerals shaped when lakes and streams as soon as rippled over the Gale Crater and deposited sediment at what’s now the bottom of Mount Sharp, the 3-mile-high (5-kilometer-high) mountain whose foothills Curiosity has been rising since 2014. Increased up the mountain within the transition zone, Curiosity’s observations present that the streams dried up in droplets and shaped sand dunes above the lake sediments.

“We now not see the lake deposits we noticed years decrease on Mount Sharp,” mentioned Ashwin Vasavada, Curiosity’s mission scientist at NASA’s Jet Propulsion Laboratory in Southern California. “As an alternative, we see loads of proof of drier climates, reminiscent of dry dunes that generally had currents round them. It’s a nice change of lakes which will have lasted tens of millions of years earlier than. ”

Because the rover climbs greater by the transition zone, it detects much less clay and extra sulfate. Curiosity will quickly drill the final rock pattern it can take on this zone, offering a extra detailed take a look at the altering mineral composition of those rocks.

Distinctive geological options additionally stand out on this zone. The hills within the space most likely started in a dry setting of huge, windswept sand dunes, which ultimately hardened into rock. Alternating within the stays of those dunes are different sediments carried by water, maybe deposited in dams or small streams that after weaved between the dunes. These sediments now seem as erosion-resistant stacks of flaky layers, reminiscent of one nicknamed “The Prow.”

To make the story richer and extra complicated, realizing that there have been a number of intervals wherein groundwater ebbed and flowed over time left a jumble of puzzle items for Curiosity’s scientists to compile into an correct timeline.

Ten years later, go robust

Curiosity will rejoice its tenth 12 months on March 5 August. Whereas the rover exhibits its age after a full decade of exploration, nothing has stopped it from persevering with its climb.

On June 7, Curiosity went into secure mode after detecting a temperature studying on an instrument management case within the trunk of the automotive that was hotter than anticipated. Secure mode happens when a spacecraft detects an issue and routinely shuts off all the pieces however its most important capabilities in order that engineers can assess the scenario.

Though Curiosity left secure mode and returned to regular operations two days later, JPL engineers are nonetheless analyzing the precise reason behind the issue. They believe that secure mode was activated after a temperature sensor offered an inaccurate measurement, and there’s no signal that it’ll considerably have an effect on robber operations, as backup temperature sensors can make sure that the electronics contained in the rover physique don’t overheat. .

The rover’s aluminum wheels additionally present indicators of damage. On June 4, the engineering crew ordered Curiosity to take new pictures of its wheels – one thing it did each 3,281 toes (1,000 meters) to verify their total well being.

The crew found that the left-middle wheel had broken one among its bigger ones, the zigzag staircase subsequent to Curiosity’s wheels. This explicit wheel already had 4 damaged grousers, so now 5 of its 19 grousers are damaged.

The beforehand broken grocers have not too long ago attracted on-line consideration as a result of it seems like a number of the metallic “pores and skin” between them has fallen out of the wheel over the previous few months, leaving a niche.

The crew determined to extend its wheelbase to each 1,640 toes (500 meters) – a return to the unique cadence. A tread management algorithm has slowed wheel put on sufficient to extend the space between photos.

“We now have confirmed by soil checks that we will experience safely on the wheel rims if vital,” says Megan Lin, Curiosity’s mission supervisor at JPL. “If we’re ever reached the purpose the place a single wheel has damaged a majority of its grosers, we will do a managed break to shake off the items which are left. As a result of latest traits, it appears unlikely that we are going to take such steps. “The wheels maintain on tight and supply the traction we have to maintain climbing.”
