NASA’s Curiosity Rover On The Drilling Mars Rocks Again: NASA’s Curiosity Mars rover has successfully collected the first rock samples on the red planet in over a year, using a new way to drill rocks and extract powder from them.
NASA’s Curiosity Rover On The Drilling Mars Rocks Again
Curiosity tested percussive drilling this past weekend, penetrating about two inches into a target called Duluth.
NASA’s Jet Propulsion Laboratory (JPL) in the US has been testing this drilling technique since a mechanical problem took Curiosity’s drill offline in the year December 2016.
This technique is called Feed Extended Drilling, keeps the drill’s bit extended out past two stabiliser posts that were initially used to steady the drill against Martian rocks.
It lets Curiosity drill using the force of its robotic arm, a little more like the way a human would drill into a wall at home.
The team used great ingenuity to devise a new drilling technique and implement it on another planet, said Steve Lee, Curiosity Deputy Project Manager at JPL.
Those are two vital inches of innovation from 60 million miles away. We’re thrilled that the result was so successful,” said Lee.
Drilling is a vitally important part of Curiosity’s capabilities to study Mars. Inside the rover are two laboratories that can conduct chemical and mineralogical analyses of rock and soil samples.
The samples are acquiring from Gale Crater, which the rover has been exploring since the year 2012. Curiosity’s science team has been eager to get the drill working before the rover leaves its current location near Vera Rubin Ridge.
Fortunately, it was near enough to drill targets like Duluth to drive back down the ridge. Sunday’s drill sample represents a quick taste of the region before Curiosity moves.
Demonstrates that Curiosity’s percussive drilling technique works are a milestone in itself. But that does not mean the work is over for engineers at JPL.
We’ve been developing this new drilling technique for over a year, but our job is not doing once a sample has collected on Mars,” said Tom Green, a systems engineer who helped develop and test Curiosity’s new drilling method.
With each new test, we carefully examine the data to look for improvements we can make and then head back to our test bed to iterate on the process,” said Green.
So, these are the points to describe on the NASA’s Curiosity rover on the drilling Mars rocks again.
