In a spectacular new Mars selfie, rover Curiosity stands proud on the bedrock at the base of Mount Sharp at it's Mojave work site in an area nicknamed Pahrump Hills.
If observations made by ESA's Mars Express are indicative of similar processes seen on Earth, these ancient Martian hills may also hide hidden deposits of ice.
'Mojave' may have cracked under the pressure from Curiosity's drill, but mission scientists are excited about studying fresh rock that hasn't been exposed since its formation millions of years ago.
In new photographs sent to Earth from NASA's Mars rover Curiosity, you'd be forgiven in thinking that the one-ton robot has botched some home repairs.
NASA's veteran Mars rover Opportunity has climbed its highest peak in 40 months of exploring the rim of Endeavour crater, despite suffering 'amnesia' issues with its on board flash memory.
There are compelling structures in a slab of sedimentary Mars rock, but their discovery alone won't prove there was ancient life on Mars.
Inevitable age-related issues have surfaced for Mars rover Opportunity and mission engineers are being challenged by an increasingly troubling bout of flash memory glitches.
Although this crater rim is entering summer, its south-facing slopes are still festively frosted in ice.
