Immense decision! Curiosity rover keeps following that that you would possibly well perhaps recount about Mars river remnant

For the previous month, NASA’s Curiosity rover has been shadowing Gediz Vallis, a channel that scientists recount might be the fossil of an frail Martian river. 

Closing week, Curiosity reached the north facet of Pinnacle Ridge, piece of a rock wall that looms over Gediz Vallis. Genuinely, after Curiosity navigated bumpy ground to enact that, it found that the ridge’s south facet is navigable.

That left Curiosity’s overseers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California with a decision: Must unruffled they assist on their deliberate course, persevering with to power alongside Gediz Vallis unless they attain a degree where the rover can substandard it? Or might well perhaps unruffled they take dangle of a diversion to gain Pinnacle Ridge’s south facet?

If Curiosity stayed on Pinnacle Ridge, it might well probably perhaps give its overseers a deep look into the ridge’s rocks. These rocks might well perhaps have once been touched by working water and maintain traces of that previous. On the opposite hand, the rocks on Pinnacle Ridge’s south facet might well perhaps speak them little that they hadn’t already seen by taking a peek on the ridge’s north facet.

Within the period in-between, engaging alongside Gediz Vallis might well perhaps allow them to in finding other aspects of Mars. Nonetheless departing Pinnacle Ridge might well perhaps point out leaving behind a — very literally — once-in-a-lifetime change to gain out about frail Martian working water.

So deliberated approximately two dozen mission scientists — incandescent they’d most bright hours to mediate on Curiosity’s direction. “We talked lots about how the rocks shall we plan from our most up-to-date location in contrast with the rocks we already investigated on the north facet,” Abigail Fraeman, planetary geologist at JPL, acknowledged in a weblog post.

Indirectly, the scientists determined to movement alongside, persevering with on the Gediz Vallis direction. First, Curiosity’s devices will take dangle of some chemical measurements of the rocks straight away below the rover’s wheels. Then, the rover will likely be on its technique.

“I basically like operations days esteem on the present time. We came on this morning with a really new Martian vista to handle, and then we needed to work collectively as a crew to fabricate a fast decision about what to enact subsequent,” Fraeman acknowledged.
