Regardless of indications of wear, the brave spacecraft will begin an exhilarating brand-new chapter of its objective as it climbs a Martian mountain.
10 years back, on August 5, 2012, a jetpack reduced NASAs Curiosity rover onto the Red Planet. This was the beginning of the SUV-size explorers pursuit of proof that Mars had the conditions required to support microscopic life billions of years earlier.

Over the past 10 years, Curiosity has actually driven almost 18 miles (29 kilometers) and ascended 2,050 feet (625 meters) as it checks out Gale Crater and the foothills of Mount Sharp within it. The Mars rover has evaluated 41 rock and soil samples, depending on a suite of science instruments to discover what they reveal about Earths rocky brother or sister. Its success has actually pushed a team of engineers to design methods to lessen wear and tear and keep the rover rolling. In truth, Curiositys objective was just recently extended for another 3 years, allowing it to continue among NASAs fleet of crucial astrobiological missions.

A Bounty of Science.
Its been a hectic decade for Curiosity. The roaming explorer has studied the Red Planets skies, capturing pictures of shining clouds and wandering moons. It radiation sensing unit is helping NASA find out how to keep future astronauts safe by determining the quantity of high-energy radiation they would be exposed to on the Martian surface.
Many considerably, Curiosity has actually discovered that liquid water, as well as the chemical structure blocks and nutrients required for supporting life, were present for at least tens of millions of years in Gale Crater. The crater once held a lake, the size of which waxed and waned gradually. This suggests that each layer greater up on Mount Sharp acts as a record of a more current age of Mars environment.
Now, the brave rover is driving through a canyon that marks the shift to a new area, one believed to have actually formed as water was drying, leaving salty minerals called sulfates.
” Were seeing evidence of dramatic changes in the ancient Martian climate,” stated Ashwin Vasavada, Curiositys task researcher at NASAs Jet Propulsion Laboratory (JPL) in Southern California. “The concern now is whether the habitable conditions that Curiosity has actually discovered already persisted through these changes. Did they vanish, never ever to return, or did they come and go over countless years?”.
Interest has made striking development up the mountain. Back in 2015, the group caught a “postcard” image (see listed below) of distant buttes. A mere speck within that image is a Curiosity-size boulder nicknamed “Ilha Novo Destino”– and, almost 7 years later on, the rover rotated by it last month on the method to the sulfate-bearing area.
The Curiosity team plans to spend the next couple of years checking out the sulfate-rich location. Within it, they have targets in mind like the Gediz Vallis channel, which may have formed throughout a flood late in Mount Sharps history, and large cemented fractures that show the results of groundwater greater up the mountain.
This scene was caught by Curiosity on September 9, 2015, when NASAs Mars rover was numerous miles from its present place. To the left of that is “Paraitepuy Pass,” which Curiosity is now taking a trip through.
How to Keep a Rover on a Roll.
Whats Curiositys secret to preserving an active way of life at the ripe old age of 10? A team of numerous devoted engineers, naturally, working both personally at JPL and remotely from home.
They brochure each and every crack in the wheels, test every line of computer code prior to its beamed into space, and drill into limitless rock samples in JPLs Mars Yard, making sure Curiosity can securely do the exact same.
” As quickly as you arrive on Mars, everything you do is based on the fact that theres no one around to repair it for 100 million miles,” stated Andy Mishkin, Curiositys acting task supervisor at JPL. “Its all about making intelligent use of whats currently on your rover.”.
Interests robotic drilling process has actually been reinvented numerous times considering that landing. At one point, the drill was offline for more than a year as engineers revamped its usage to be more like a portable drill. More just recently, a set of braking systems that allow the robotic arm to move or remain in location stopped working. Although the arm has actually been running as usual because engineers engaged a set of spares, the group has also discovered to drill more gently to preserve the brand-new brakes.
To reduce damage to the wheels, engineers watch out for treacherous areas like the knife-edged “gator-back” surface they found just recently. They developed a traction-control algorithm to assist also.
The team has taken a comparable method to handling the rovers slowly decreasing power. Interest counts on a long-lived nuclear-powered battery rather than solar panels to continue rolling. As the plutonium pellets in the battery decay, they produce heat that the rover converts into power. Due to the fact that of the pellets steady decay, the rover cant do rather as much in a day as it did during its first year.
Mishkin stated the team is continuing to budget plan how much energy the rover uses each day, and has actually determined which activities can be done in parallel to optimize the energy offered to the rover. “Curiosity is absolutely doing more multitasking where its safe to do so,” Mishkin added.
Through cautious preparation and engineering hacks, the team has every expectation the plucky rover still has years of exploring ahead of it.
