Engineers have been working to restore the Rover's full drilling capacity over the past year, which was hampered by a mechanical problem in 2016. Later this weekend, they will add a new technique to Schlagwerk is used on Mars.
This new technique is called "Feed Extended Drilling" or "FED" and makes Curiosity drill more than someone who is too Home and uses the power of his robotic arm to push his drill forward as it turns. The new version of FED adds hammer power to the drill.
The exercise was tested at the end of February with the FED technique without a hammer mechanism, but did not provide a sample of rock, but provided valuable results for NASA's Jet Propulsion Laboratory engineers in Pasadena, California, data from the percussive tests currently scheduled for Saturday night will help them to further refine the drilling technology in the coming months.
"This is our next big test to to reshape the holes as they did before, "said Steven Lee, curiosity deputy project manager at JPL. "Depending on how it works, we can fine-tune the process and try to increase the force we use in drilling."
The strategy was to prototype these new methods while driving, Lee said. If Drill Drilling successfully produces a sample this week, the team will immediately begin testing a new method for delivering that sample to the rover's internal laboratories. In the meantime, JPL engineers will continue to work on advanced drilling technology. At the same time, they are developing new ways to improve the performance of the drill.
This week's test will do two things, possibly producing important science, said Curiosity Project scientist Ashwin Vasavada of JPL. The Rover has made its way along the Vera Rubin Ridge to an uphill clay-enriched area that the research team would love to explore. Expecting to receive samples, the Rover reversed direction in mid-April and headed for the mountainside.
"We intentionally backtracked because the team believes there is a high value in drilling rocks that forms a 200-foot-thick layer [about 60 meters] under the ridge," Vasavada said. "Fortunately, we're able to cover a short distance and still pick up a target on top of this layer."
The rock type would fill a gap in the knowledge of the science team on Mount Sharp; After all, they would like to analyze samples of all the important types of rocks they encounter with the Rovers' laboratories.
"Every layer of Mount Sharp reveals a chapter in the history of Mars without the drill to skim our first pass through that layer like the chapter, and now we get a chance to read it in detail," added Vasavada ,
