Solander Point

Solander Point also offers plenty of ground that is tilted toward the north, which is favorable for the solar-powered rover to stay active and mobile through the coming Martian southern-hemisphere winter.

“We’re heading to a 15-degree north-facing slope with a goal of getting there well before winter,” said John Callas of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., project manager for the Mars Exploration Rover Project. The minimum-sunshine days of this sixth Martian winter for Opportunity will come in February 2014.

NASA’s Mars Exploration Rover Project launched twin rovers in 2003: Spirit on June 10 and Opportunity on July 7. Both rovers landed in January 2004, completed three-month prime missions and began years of bonus, extended missions. Both found evidence of wet environments on ancient Mars. Spirit ceased operations during its fourth Martian winter, in 2010. Opportunity shows symptoms of aging, such as loss of motion in some joints, but continues to accomplish groundbreaking exploration and science.

Shortly before leaving Cape York last month, Opportunity used the rock abrasion tool, the alpha particle X-ray spectrometer and the microscopic imager on its robotic arm to examine a rock called “Esperance” and found a combination of elements pointing to clay-mineral composition.

“The Esperance results are some of the most important findings of our entire mission,” said Steve Squyres of Cornell University, Ithaca, N.Y., principal investigator for the mission. “The composition tells us about the environmental conditions that altered the minerals. A lot of water moved through this rock.”

Cape York exposes just a few yards, or meters, of vertical cross-section through geological layering. Solander Point exposes roughly 10 times as much. Researchers hope to find evidence about different stages in the history of ancient Martian environments. The rim of Endeavour Crater displays older rocks than what Opportunity examined at Eagle, Endurance, Victoria and Santa Maria craters during the first eight years of the rover’s work on Mars.

  1. I understand the wonderful little rover Opportunity is to travel to Solander Point and could possibly examine Nobby’s Head on the Way. That feature is of great interest to us here in the Hunter Valley of New South Wales. In May 1770 Captain James Cook RN aboard His Majesty’s Bark Endeavour passed and noted the small hill island Nobbys Head a local icon that stands guard at the entrance to the Hunter River. The Martian Nobby’s Head looks to be a very interesting feature on the Endeavour crater rim and as such would or could be a suitable feature to inspect on the way to Solander Point. Solander was a Swedish scientist and astronomer who sailed with Cook on that epic voyage to Tahiti to observe the Transit of Venus across the face of the Sun and they then travelled south and west to search for the Great Southern Land which Cook and the Endeavour crew found and mapped calling it New South Wales and claiming the vast land for the English Crown. A close up view of the feature Nobbys Head would be of great interest to us here in the Hunter Valley of New South Wales, Australia.

  2. Interesting, hope you get the look, I’ll be sure to post it. On Solander, I keep wanting to spell the name Sjolander.
