Vista From Mars Rover Looks Back Over Journey So Far

A breathtaking picture that NASA’s Curiosity Mars corsair took from a mountainside shallow provides a unconditional perspective of pivotal sites visited given a rover’s 2012 landing, and a soaring surroundings.

Curiosity Project Scientist Ashwin Vasavada gives a minute debate of a Mars rover’s perspective in Gale Crater. The white-balanced stage looks behind over a tour so far.

The perspective from “Vera Rubin Ridge” on a north side of Mount Sharp encompasses many of a 11-mile (18-kilometer) track a corsair has driven from a 2012 alighting site, all inside Gale Crater. One towering on a northern setting is about 50 miles (about 85 kilometers) away, good outward of a crater, yet many of a scene’s setting is a crater’s northern rim, roughly one-third that widen divided and 1.2 miles (2 kilometers) above a rover.

Curiosity’s Mast Camera, or Mastcam, took a member images of a scenery 3 months ago while a corsair paused on a northern corner of Vera Rubin Ridge. The goal has subsequently approached a southern corner of a shallow and examined several outcrop locations along a way.

Last week, a Curiosity group on Earth perceived thriving new images from a corsair by a record-setting send by NASA’s MAVEN orbiter — leading a gigabit of information during a singular send event from Mars for a initial time in history.

The group is scheming to resume use of Curiosity’s cavalcade for appropriation powdered stone samples to be analyzed by laboratory instruments inside a rover, some-more than a year after a many new of a 15 times a cavalcade has pulled representation element from Martian rocks.

Inside an Impact Crater

Mount Sharp stands in a center of Gale Crater, that is 96 miles (154 kilometers) in diameter.

“Even yet Curiosity has been usually climbing for 5 years, this is a initial time we could demeanour behind and see a whole goal laid out subsequent us,” pronounced Curiosity Project Scientist Ashwin Vasavada of NASA’s Jet Propulsion Laboratory, Pasadena, California. “From a roost on Vera Rubin Ridge, a immeasurable plains of a void building widen out to a fantastic towering operation that forms a northern corner of Gale Crater.” The corsair photographed a stage shortly before northern Mars’ winter solstice, a deteriorate of transparent skies, gaining a pointy perspective of apart details.

Curiosity’s accurate alighting mark on a building of a void lies out of steer behind a slight rise, though a stage includes “Yellowknife Bay.” That’s where, in 2013, a goal found justification of an ancient freshwater-lake sourroundings that offering all of a simple chemical mixture for microbial life. Farther north are a channel and fan of Peace Vallis, corpse of a streams that carried H2O and lees into a void about 3 billion years ago.

Sites such as “Kimberley” and “Murray Buttes” along a rover’s track are noted on an annotated posting of a panorama. The Mastcam available both a wider chronicle of a stage (from southwest to northeast) with a left-eye, 34-millimeter-lens camera and a some-more detailed, narrower chronicle with a right-eye, 100-millimeter-lens camera.

The site from that these images were taken sits 1,073 feet (327 meters) in betterment above Curiosity’s alighting site. Since withdrawal that site, a corsair has climbed another 85 feet (26 meters) in elevation. In new days, a Mastcam has available member images for a scenery looking ascending southward toward a mission’s subsequent vital end area. That is called a “Clay Unit” since observations from circuit rescued clay minerals there.

Record Relay

The event for some high-volume send sessions with a MAVEN orbiter is assisting a Curiosity group benefit a annuity of images and other information this month.

Most information from Curiosity, by a years, have been relayed to Earth by NASA’s Mars Reconnaissance Orbiter (MRO) and Mars Odyssey orbiter, that fly in scarcely circular, scarcely frigid orbits predictably flitting over Curiosity during about a same times each day. MAVEN, for Mars Atmosphere and Volatile Evolution, flies an elliptical circuit varying some-more than 40-fold from a nearest to farthest indicate from Mars. This suits MAVEN’s scholarship concentration on Mars’ atmosphere though formula in non-static coverage for relaying corsair data. Usually, MAVEN passes over corsair locations when a widen is too vast for optimal relays. However, during occasional durations when a low indicate of a circuit is nearby Curiosity’s plcae on Mars, a relays can offer awfully well.

“MAVEN really has a intensity to pierce lots of information for us, and we design to make even some-more use of it in a future,” pronounced JPL’s Roy Gladden, manager of NASA’s Mars Relay Network Office. The Jan. 22 send of 1,006 megabits surfaced a prior record of 840 megabits, also set by MAVEN, though competence in spin be bested by other auspicious MAVEN send opportunities in entrance days.

The corsair group intends to put Curiosity’s cavalcade to work on Vera Rubin Ridge before proceding to a Clay Unit. Resuming use of a cavalcade requires an brazen workaround for a automatic problem that seemed in late 2016 and dangling use of a drill. A engine within a cavalcade that advances a bit relations to stabilizer points no longer operates reliably.The workaround being evaluated entirely on a exam corsair during JPL does not use a stabilizer points. It moves a whole cavalcade forward, with bit extended, by suit of a robotic arm.
