There must be quite a storage on the rovers. Imagine they do their work and are on the side of Mars that's not focusing to earth. They need to store the data until they get contact again.

The rovers are a testament to good engineering, still&nbsp;working so long after they were intended to without any possibility for maintenance (other than the software upgrades). I wonder what kind of capacity it has in terms of memory; obviously it needs quite a lot of space&nbsp;to store&nbsp;the scientific data and other stuff before it sends it home, but what is available for e.g. the autonomous driving program?<BR><BR>A technical note about the video: I found having the voices separated (Charles in the left channel and Dave Lavery in the right channel) to be very distracting. If you look at professional video, even hollywood movies, they almost never put voices in the side channels (and if they do, it's for a short time only and usually a character that's off screen). Voice needs to be in the center pretty much always.http://channel9.msdn.com/posts/Charles/Channel-9-on-Mars-Inside-the-Mars-Exploration-Mission-Past-Present-and-Future/?CommentID=443751Tue, 18 Nov 2008 15:28:22 GMThttp://channel9.msdn.com/posts/Charles/Channel-9-on-Mars-Inside-the-Mars-Exploration-Mission-Past-Present-and-Future/?CommentID=4437510http://channel9.msdn.com/443751/WebViewBug.aspx?EVT=0Yeah awesome video.

Thanks Charles.Christian Liensberger0http://channel9.msdn.com/443549/Trackback.aspxAs we discussed in the interview, the software that drives the rovers is written in pure C (which is an evolutionary step for NASA given that just a few years ago they were still writing in Assembler). There is no room for a general purpose operating system given the extreme memory constraints. The rovers are running&nbsp;VxWorks RTOS (from WindRiver Software). There is a place for Microsoft Robotics, but it's not on the rovers themselves... Stay tuned.<BR><BR>Chttp://channel9.msdn.com/posts/Charles/Channel-9-on-Mars-Inside-the-Mars-Exploration-Mission-Past-Present-and-Future/?CommentID=443547Mon, 17 Nov 2008 19:05:44 GMThttp://channel9.msdn.com/posts/Charles/Channel-9-on-Mars-Inside-the-Mars-Exploration-Mission-Past-Present-and-Future/?CommentID=4435470http://channel9.msdn.com/443547/WebViewBug.aspx?EVT=0As we discussed in the interview, the software that drives the rovers is written in pure C (which is an evolutionary step for NASA given that just a few years ago they were still writing in Assembler).
