Solander Point is at the north end of the west-southwestern ridgeline of Endeavour crater on the planet Mars. It is named after the Swedish scientist Daniel Solander, who was the first university-educated scientist to set foot on Australian soil at Botany Bay in 1770.

Solander Point was visited in 2013 by the Mars Exploration Rover-B Opportunity, a robotic rover that was active on Mars from 2004-2018. [1]

By early July 2013 Opportunity was approaching it from the North, after previously examining outcrops on the northwest edge of the crater, north of Solander.[2] The rover drove south from Cape York through Botany Bay to travel to Solander.[3] By July 2, 2013, it was about half-way there.[3] The area was imaged from Martian orbit by HiRISE on July 8, 2013, data which aids the rover team in understanding the terrain and planning rover traverses.[4] The rover has been making good time on its approach to Solander, giving the opportunity to investigate a curious area of terrain in the crater.[5][6] At the start of August, the rover was less than 100 meters (328 ft) from Solander,[7] and arrived at its base in the following days.[8] Its arrival signaled the availability of a northward facing slope, useful for angling to collect more sunlight during the Martian winter.[8] In October and November 2013, the rover climbed up the north end of Solander.[9] By December 2013, the rover reached the top of Solander point hill as the 10 year anniversary of its landing on Mars neared.[10] After Solander point Opportunity moved along Murray Ridge, and then south to Cape Tribulation.[11]

Between Solander Point and, to north of it Cape York, both of which are raised up, is a lower area that is noted to be a part of the Burns Formation.[12] The Burns Formation extends all the way back to Opportunity's landing site by Eagle crater, and it was heavily studied prior to this time by the rover.[13] The Burns Formation is "high in sulfate bearing minerals" according to NASA.[14] Solander Point lies at the geological contact line between the Burns Formation, and what is thought to be an even older geological region.[15]
