Spirit Approaching "von Braun": Mosaic at Spaceflight Now website, 25 Jun 09
See our newly published Spirit mosiac from Sol 1869 here: http://www.spaceflightnow.com/news/n0906/25spirit/ JPL rover tests next week begin efforts to free Spirit BY CRAIG COVAULT SPACEFLIGHT NOW Posted: June 25, 2009 Jet Propulsion Laboratory engineers working to free the rover Spirit from its slippery Martian trap will begin JPL test rover drives by June 29, aimed at freeing Spirit to continue roving by late July. The objective will be to demonstrate how the rover wheels can "get a bite" on simulated slippery Martian soil that JPL has formulated using the same gritty, white material that dentists use to clean teeth, and which is also a key component of dynamite. ..... small version here: Caption: Mosaic of the area abeam Home Plate where Spirit remains stuck was made especially for Spaceflight Now. It shows smooth area, foreground, that concealed slippery water related sulfate material where rover became stuck. Once free, Spirit will drive to area near the unusually capped hill ahead designated Von Braun to sample water related evidence there.

Once free, Spirit will drive to area near the unusually capped hill ahead designated Von Braun to sample water related evidence there. So, Craig has no doubt about it! -------------------- |

Spirit mosaic reprinted today (July 2, 09) at Universe Today in this article about Tee-Bee adventures here:
http://www.universetoday.com/2009/07/02/te...s-a-good-thing/ http://www.universetoday.com/2009/07/02/te...-by-ken-kremer/ So, Craig has no doubt about it! based on quotes from Squyres about the Home plate area: Spirit literally fell into a small camouflaged pit of empiric sulfate salts, a highly powdery and slippery by product of the presence of ancient water with volcanic soils, says Steve Squyres of Cornell University, principal investigator for the mission. |
