NASA's Curiosity rover tests new drilling method on Mars
Washington, May 24: After a mechanical problem took NASA Mars rover Curiosity's drill offline in December 2016, it has now successfully tested a new drilling method on the Red Planet, making a 50-millimetre deep hole in a target called "Duluth", NASA has said.
Engineers working with the Curiosity Mars rover have been hard at work testing a new way for the rover to drill rocks and extract powder from them.
On May 20, that effort produced the first drilled sample on Mars in more than a year, NASA said in a statement on Wednesday.
The new technique, called Feed Extended Drilling, keeps the drill's bit extended out past two stabiliser posts that were originally 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 tremendous ingenuity to devise a new drilling technique and implement it on another planet," said Curiosity Deputy Project Manager Steve Lee of NASA's Jet Propulsion Laboratory in Pasadena, California.
"Those are two vital inches of innovation from 60 million miles away. We're thrilled that the result was so successful," Lee said.
Drilling is a vitally important part of Curiosity's capabilities to study Mars.
Inside the rover are two laboratories that are able to conduct chemical and mineralogical analyses of rock and soil samples.
The samples are acquired from Gale Crater, which the rover has been exploring since 2012.
"We've been developing this new drilling technique for over a year, but our job isn't done once a sample has been collected on Mars," said JPL's Tom Green, a systems engineer who helped develop and test Curiosity's new drilling method.
"With each new test, we closely examine the data to look for improvements we can make and then head back to our test bed to iterate on the process."
There's also the next step to work on -- delivering the rock sample from the drill bit to the two laboratories inside the rover.
As soon as this Friday, the Curiosity team will test a new process for delivering samples into the rover's laboratories, NASA said.

Inappropriate for MLAs seeking free IPL tickets, says D.K. Suresh
Bengaluru: Bengaluru Milk Union Ltd President D.K. Suresh on Monday said it is inappropriate for MLAs to seek free IPL tickets, adding that those interested in watching matches should pay for them personally.
Speaking to reporters near his residence in Sadashivanagar, he said, “IPL is a commercial tournament and does not represent the country. It is not right for public representatives to focus too much on such matters.”
Referring to the recent controversy during the RCB celebrations, he said, “let us find out who benefited the most from the statements made during the incident.” He also pointed out that BJP MLAs had received IPL tickets as well.
Responding to discussions about relocating the Chinnaswamy Stadium, Suresh said the government has already approved the construction of a new stadium at a location he had proposed.
“I had suggested building a stadium in Surya City and submitted a proposal for it. Bengaluru needs four stadiums in four directions to cater to its growing population and encourage youth participation in sports,” he said.
He noted that apart from Kanteerava Stadium, KSCA, and the Football Stadium, there are limited facilities in the city.
“When I was a Lok Sabha member, I had proposed allocating 100 acres in my constituency at Surya City. The land was later earmarked and the plan approved,” he added.
Suresh said he has discussed the project with Minister Zameer Ahmed Khan, Rajiv Gandhi Housing Corporation Chairman Shivalingegowda, and Anekal MLA Shivanna.
“The Cabinet has now approved the project, and a stadium will be developed on around 50–60 acres,” he said.
He further added that he has requested the Deputy Chief Minister to build another stadium at Shivarama Karanth Layout through the BDA, where 40 acres have been allocated. Plans are also being discussed to develop a well-equipped stadium in Bidadi.
Commending state government's recent bilingual policy move, Suresh said forcing children to learn three languages could affect their comprehension.
“It is a good decision to make two languages compulsory. Learning a third language should be left to the choice of students and parents,” he said.
Responding to criticism from BJP leaders, he said their tendency is to oppose every decision of the government.
“To please their central leadership, they take a pro-Hindi stance. Instead, they should advocate for the adoption of Kannada in all states,” he said.
When asked about the earlier three-language policy under Congress, he said, “the situation is different now. Today, the focus should be on quality learning. Kannada should remain the primary language, while students and parents can choose an additional language.”
