NASA’s Curiosity rover productively landed in Gale Crater on Mars on August 5, 2012, to research for evidence that the Purple World could once have supported Earth-like microbial everyday living.
Because landing on Mars in August 2012, Curiosity has been discovering Mt. Sharp in Gale Crater. Impression credit rating: NASA / JPL-Caltech.
Curiosity was released aboard an Atlas V rocket from Cape Canaveral Air Force Station, Florida on November 26, 2011.
The rover landed on Mars on August 5, 2012 at 10:32 p.m. PDT (1:32 a.m. EDT on August 6) making use of a collection of complicated landing maneuvers hardly ever before tried.
The specialised landing sequence, which used a huge parachute, a jet-controlled descent vehicle and a bungee-like equipment called a sky crane, was devised since examined landing methods employed throughout former rover missions could not safely accommodate the significantly greater and heavier rover.
Given that the landing, Curiosity has pushed practically 29 km (18 miles) and ascended 625 (2,050 ft) as it explores Gale Crater and the foothills of Mount Sharp within it.
The rover has acquired 494,540 visuals, returned 3,102 gigabytes of data to Earth, and yielded 883 science papers.
It has analyzed 41 rock and soil samples, relying on a suite of science instruments to study what they reveal about Earth’s rocky sibling.
And it’s pushed a team of Curiosity engineers to devise methods to limit use and tear and continue to keep the rover rolling.
In fact, Curiosity’s mission was recently extended for yet another a few years, permitting it to proceed between NASA’s fleet of significant astrobiological missions.
“As before long as you land on Mars, every thing you do is centered on the point that there is no one around to repair it for 100 million miles,” explained Curiosity’s acting challenge manager Andy Mishkin, a researcher at NASA’s Jet Propulsion Laboratory.
“It’s all about producing intelligent use of what is by now on your rover.”

Curiosity has examined the Red Planet’s skies, capturing images of shining clouds and drifting moons.
The rover’s radiation sensor lets researchers measure the total of high-electrical power radiation foreseeable future astronauts would be exposed to on the Martian surface, encouraging NASA figure out how to retain them protected.
But most critical, Curiosity has determined that liquid h2o as nicely as the chemical setting up blocks and nutrients needed for supporting existence have been current for at least tens of millions of several years in Gale Crater.
The crater at the time held a lake, the dimension of which waxed and waned above time. Each individual layer bigger up on Mount Sharp serves as a document of a extra the latest era of Mars’ ecosystem.
Now, the rover is driving via a canyon that marks the transition to a new region, a person thought to have formed as h2o was drying out, leaving at the rear of salty minerals named sulfates.
“We’re looking at proof of remarkable adjustments in the ancient Martian weather,” claimed Curiosity’s task scientist Dr. Ashwin Vasavada, also from NASA’s Jet Propulsion Laboratory.
“The concern now is no matter whether the habitable situations that Curiosity has found up to now persisted via these variations.”
“Did they vanish, never ever to return, or did they come and go more than thousands and thousands of many years?”
Back in 2015, the rover captured a postcard graphic of distant buttes.
A mere speck in just that image is a Curiosity-dimension boulder nicknamed Ilha Novo Destino — and, nearly 7 yrs later, the rover trundled by it final thirty day period on the way to the sulfate-bearing region.
The Curiosity crew ideas to shell out the following couple of several years checking out the sulfate-loaded place.
Within it, they have targets in mind like the Gediz Vallis channel, which could have shaped for the duration of a flood late in Mount Sharp’s historical past, and big cemented fractures that demonstrate the effects of groundwater higher up the mountain.
“Our group is continuing to budget how a great deal vitality the rover uses every single working day, and has figured out which functions can be performed in parallel to enhance the electricity out there to the rover,” Mishkin mentioned.
“Curiosity is absolutely carrying out much more multitasking the place it is secure to do so.”
