Mars 2020 rover takes first and last test drive

Engineers on December 17 gave the Mars 2020 rover its first and last test drive before it is launched in July 2020.

In a 10-plus-hour marathon on Tuesday that demonstrated all the systems working in concert, the rover steered, turned and drove in 3-foot (1-meter) increments over small ramps covered with special static-control mats. Since these systems performed well under Earth’s gravity, engineers expect them to perform well under Mars’ gravity, which is only three-eighths as strong. The rover was also able to gather data with the Radar Imager for Mars’ Subsurface Experiment (RIMFAX).

I have embedded a short video showing a tiny part of that driving test below the fold. This is the last and only time we will ever be able to see the rover move. Once it is on Mars in Jezero Crater there will be no third party cameras to record its travels.

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.

 

Autographed printed copies are also available at discount directly from me (hardback $24.95; paperback $14.95; Shipping cost for either: $5.00). Just email me at zimmerman @ nasw dot org.
