Debris in Perseverance core sample equipment

Debris in core sample carousel on Perseverance
Click for full image.

In attempting to store its sixth core sample on Mars last week, engineers discovered that Perseverance could not do so because several small pieces of the core sample had fallen into the equipment and prevented the drilling bit with the core from inserting itself completely into the sample storage carousel.

To understand the issue precisely, the engineers commanded Perseverance to first extract the bit from the carousel so they could get pictures of it.

The extraction took place yesterday (1/6) and data was downlinked early this morning. These most recent downlinked images confirm that inside the bit carousel there are a few pieces of pebble-sized debris. The team is confident that these are fragments of the cored rock that fell out of the sample tube at the time of Coring Bit Dropoff, and that they prevented the bit from seating completely in the bit carousel.

The photo to the right shows that material at the image’s bottom.

It appears this issue was anticipated when the rover was designed giving engineers a way to remove the debris. They plan to do so, but will proceed slowly as this will be the first time it will be attempted on Mars.

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.

    You mean to tell me that they didn’t put an air hose on this thing. Geeze! I mean it’s got it’s own nuclear reactor but no air hose?
