Confirmed: All debris cleared from Perseverance sample tube

Click here and here for original images.

The Perseverance science team today announced in an update that their effort to clear the sample tube of bits of core sample has succeeded, as indicated partly by the two images above that I posted on January 19th.

According to the report, the two small pieces visible bottom center fell out after two small rotations of the carousal. Other pieces however remained, and these were removed as followed:

On Monday, Jan. 17, the team commanded another operation of the rotary percussive drill in an attempt to dislodge more material from the tube. With the tube’s open end still pointed towards the surface, we essentially shook the heck out of it for 208 seconds – by means of the percussive function on the drill. Mastcam-Z imagery taken after the event shows that multiple pieces of sample were dumped onto the surface. Is Tube 261 clear of rock sample? We have new Mastcam-Z images looking down the drill bit into the sample container that indicate little if any debris from the cored-rock sample remains. The sample tube has been cleared for reuse by the project.

The team is now discussing their next step, which could be drilling a new hole at this spot or moving on.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.
