A-The Sun from Spitzer - spicules_sst_big.jpgSun "Spicules" from the Sptizer Space Telescope (SST)134 visiteCaption NASA originale: "Pictured above is perhaps the highest resolution image yet of the enigmatic "Solar Flux Tubes" known as "Spicules". Spicules dot the above frame of solar active region, but they are particularly evident as a carpet of dark tubes on the right. Time-sequenced images have recently shown that spicules "Life-span" is of about 5 minutes, starting out as tall tubes of rapidly rising gas but eventually fading as the gas peaks and falls back down to the Sun".

OPP-SOL919-1F209770154EFF758ZP1214L0M1.jpgA new trench near Victoria Crater - Sol 91953 visiteCaption NASA originale:"Opportunity is healthy and located only 218 mt(such as about 715 feet) from the rim of Victoria Crater. Opportunity's odometer clicked past the 9-Km (5,5-mile) mark as it drove 237,81 mt (about 780 feet) during the week. The terrain within the annulus, or ring, of material surrounding Victoria, is homogeneous and flat, which is favorable for long drives. The team planned a trenching activity for Sol 919 (Aug. 25, 2006) to prepare for a RA campaign during the weekend".
