Curiosity recovering from safe mode

Last week Curiosity suddenly went into safe mode, halting science operations for four days while engineers analyzed the issue.

Curiosity encountered a hurdle last Friday, when a hiccup during boot-up interrupted its planned activities and triggered a protective safe mode. The rover was brought out of this mode on Tuesday, Feb. 19, and is otherwise operating normally, having successfully booted up over 30 times without further issues.

Throughout the weekend, Curiosity was sending and receiving technical data, communicating with the team in order to help them pinpoint the cause of the issue. “We’re still not sure of its exact cause and are gathering the relevant data for analysis,” said Steven Lee, Curiosity’s deputy project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. JPL leads the Curiosity mission. “The rover experienced a one-time computer reset but has operated normally ever since, which is a good sign,” he added. “We’re currently working to take a snapshot of its memory to better understand what might have happened.”

…”In the short term, we are limiting commands to the vehicle to minimize changes to its memory,” Lee said. “We don’t want to destroy any evidence of what might have caused the computer reset. As a result, we expect science operations will be suspended for a short period of time.”

As far as I could tell, images were being uploaded to their public image page through February 20, when I did my last rover update. Since then however no new images have appeared. I fear this might be related to the computer issues Curiosity experienced in September that shut down operations for about six weeks and was never quite resolved. Of Curiosity’s two main computers both have now experienced serious problems.

Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.

He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

Available everywhere for $3.99 (before discount) at amazon, Barnes & Noble, all ebook vendors, or direct from the ebook publisher, ebookit. And if you buy it from ebookit you don't support the big tech companies and I get a bigger cut much sooner.
