Further details on the find, however, are now scarce and the rover's results have been embargoed by the journal Science until the official NASA unveiling.
New "science results from NASA's Mars Curiosity rover " will be made public at 2pm EDT on June 7.
This means no further details are to be released until the press conference, which will be hosted by Michelle Thaller, assistant director of science for communications at NASA's Planetary Science Division. Engineers at NASA spent more than a year developing a workaround drilling technique called Feed Extended Drilling, or FED, which uses the rover's robotic arm to direct and push the drill into the ground as the drill bit spins.
During the announcement, you'll hear from two scientists who work at at NASA's Goddard Space Flight Center in Maryland, along with two researchers from its Jet Propulsion Laboratory in California.
After more than a year, NASA's Curiosity rover has successfully delivered rock powder extracted from the Martian surface to one of its two onboard labs, regaining the critical ability to analyze surface samples on the red planet.
"Has NASA found life on Mars?"
The deployment of the lab on May 31 marks a major milestone for the agency, which has worked extremely hard to fix Curiosity's drilling and sample analysis capabilities. That Parts of sample into the labs within the rover. Between these pins, the drill is extended, bores into the rock, and then recesses back into the hand to place the sample into the Collection and Handling for In-Situ Martian Rock Analysis (CHIMRA) sorting and transporting system.
Testing of both the new drilling method and sample delivery will continue to be refined as Curiosity's engineers study their results from Mars.
"This was no small feat. It represents months and months of work by our team to pull this off", said Jim Erickson, MSL project manager. But then in December 2012, the rover's mission was extended.
"The scientific team was confident that the engineers contend - are so confident that we went back to the pattern that we missed before". "It is rather impressive to have a moment such as this, five years to the assignment".
