InSight’s heat sensor begins drilling down

The German-made heat sensor hammer that the U.S. lander InSight placed on the Martian surface has begun hammering its heat sensor into the ground.

On 28 February 2019, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) ‘Mole’ fully automatically hammered its way into the Martian subsurface for the first time. In a first step, it penetrated to a depth between 18 and 50 centimetres [7 to 19 inches] into the Martian soil with 4000 hammer blows over a period of four hours. “On its way into the depths, the mole seems to have hit a stone, tilted about 15 degrees and pushed it aside or passed it,” reports Tilman Spohn, Principal Investigator of the HP3 experiment. “The Mole then worked its way up against another stone at an advanced depth until the planned four-hour operating time of the first sequence expired. Tests on Earth showed that the rod-shaped penetrometer is able to push smaller stones to the side, which is very time-consuming.

They will let the hammer cool down for a few days, and then resume hammering. If all goes well, they hope to get as much as 16 feet down.

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.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. The ebook can also be purchased direct from my ebook publisher, ebookit, in which case you don't support the big tech companies and I get a bigger cut much sooner.
