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.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Looks like a very, very complicated machine. Is there more video of the ten hour demo?
