[/caption]NASA’s Mars Opportunity rover has finally arrived at the huge Martian crater named Endeavour that simultaneously offers a mother lode of superb scenery and potentially the “Mother of all Martian Science”. The epic journey took nearly three years.
The intrepid robogirl is now climbing uphill on a Scientific quest that may well produce bountiful results towards the most important findings ever related to the search for life on Mars. Opportunity arrived at the western rim of the 13 mile (21 km) wide Endeavour crater on the 2681st Sol , or Martian day, of a mission only warrantied to last 90 Sols.
See our new Opportunity panoramic mosaics (Marco Di Lorenzo & Ken Kremer) illustrating the magnificent scenery and science targets now at hand on the surface of the Red Planet, thanks to the diligent work of the science and engineering teams who created the twin Mars Exploration Rover (MER) vehicles – Spirit & Opportunity.

Opportunity made landfall at Endeavour at a ridge of the discontinuous crater rim named Cape York and at a spot dubbed “Spirit Point” – in honor or her twin sister Spirit which stopped communicating with Earth about a year ago following more than six years of active science duty. See traverse map mosaic.
The martian robot quickly started driving northwards up the gnetle slopes of Cape York and has reached a small crater named “Odyssey” – the first science target, Dr. Matt Golembek told Universe Today. Golembek is a Senior Research Scientist with the Mars Exploration Program at the Jet Propulsion Laboratory (JPL) in Pasadena, Calif.
“Large ejecta blocks are clearly visible on the rim of Odyssey crater,” said Golembek. The crater is about 66 feet (20 m) in diameter.
Odyssey is a small impact crater of interest to the team because it features exposed material from Mars ancient Noachian era that was ejected when the crater was excavated long ago. Opportunity carefully drove over several days to one of those ejecta blocks – a flat topped rock nicknamed Tisdale 2.
“Opportunity is at a block of Odyssey crater ejecta called Tisdale 2 and the rock appears different from anything else we have seen,” Golembek explained.
Starting on Sol 2688 (Aug. 16) the rover began a science campaign time to investigate the rock with the instruments at the terminus of its robotic arm or IDD (Instrument Deployment Device) that will continue for some period of time.
“We are about to start an IDD campaign,” Golembek stated.
The team reports that the soil at Cape York is also of a different texture than any that Opportunity has seen so far on her incredible 20 mile (33 km) trek across the Meridiani Planum region of Mars. So far they haven’t seen of the iron-rich concretions, nicknamed “blueberries,” which have been plentiful on the surface along the way at numerous locations Opportunity has stopped at and investigated over the past 90 months. Initially the prime mission was projected to last 3 months – the remainder has been a huge bonus.
The science team is directing Opportunity to hunt for clay minerals, also known as phyllosilicates, that could unlock the secrets of an ancient Epoch on Mars stretching back billions and billions of years ago that was far wetter and very likely more habitable and welcoming to life’s genesis.
Phyllosilicate minerals form in neutral water that would be vastly more friendly to any potential Martian life forms – if they ever existed in the past or present. Signatures for phyllosilicates were detected by the CRISM instrument aboard NASA’s powerful Mars Reconnaissance Orbiter (MRO) spacecraft circling Mars
