NASA Curiosity Rover Gets its Drilling Groove Back on Mars

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

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. (IANS)

Anticipated Problems That May Effect NASA’s Mars Mission

According to results from the first eight analog space crews, presented at the American Association for the Advancement of Science (AAAS) annual meeting in Washington, D.C., the astronauts are able to successfully complete tasks between 20 and 60 per cent of the time.

Researchers are developing a predictive model to help NASA anticipate conflicts and communication breakdowns among crew members and tick off problems that may make or break the Mission to Mars.

NASA has formalised plans to send a manned mission to Mars, a journey that could involve 250 million miles of travel on a small spacecraft.

To understand the psychological demands of this Mars journey, Northwestern University has charted a multi-phase study conducted in two analog environments — HERA in the Johnson Space Center in Houston and the SIRIUS Mission in the NEK analog located in the Institute for Bio-Medical Problems (IBMP) in Russia.

The varsity will study the behaviour of analog astronaut crews on mock missions, complete with isolation, sleep deprivation, specially designed tasks and mission control, which mimics real space travel with delayed communication.

“Astronauts are super humans. They are people who are incredibly physically fit and extremely smart,” said Leslie DeChurch, Professor at Northwestern.

“We’re taking an already state-of-the-art crew selection system and making it even better by finding the values, traits and other characteristics that will allow NASA to compose crews that will get along,” DeChurch added.

HERA’s capsule simulator houses astronauts for up to 45 days — a mock mission control outside the capsule — that augments the realism with sound effects, vibrations and communication delays.

Those on the inside undergo sleep deprivation and try to perform tasks. The researchers collect moment-to-moment metrics about individual performance, moods, psychosocial adaptation and more.

The next phase of the research, which began on February 15, involves using the model to predict breakdowns and problems a new HERA crew will experience and making changes to “who works with whom, on what, and when”.

The experiment on the SIRIUS analog in Moscow, will begin on March 15, where four Russians and two Americans, will undertake a 120-day fictional mission around the moon, including a moon landing operation. (IANS)
