Jake Matijevic (or Jake M) is a pyramidal rock on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons ("Mount Sharp"), in Gale crater on the planet Mars. The approximate site coordinates are: 4°35′S 137°26′E / 4.59°S 137.44°E / -4.59; 137.44.

The rock was encountered by the

Curiosity rover on the way from Bradbury Landing to Glenelg Intrigue in September 2012 and measures about 25 cm (9.8 in) height and 40 cm (16 in) width.[1]

The rock was named by

Opportunity.[2]

Erosional formation of Jake M rock by wind.

The rover team determined the rock to be a suitable target for the first use of Curiosity's contact instruments, the Mars Hand Lens Imager (MAHLI) and the Alpha particle X-ray spectrometer (APXS).[3]

Analytical studies, performed on the rock by the Curiosity rover in October 2012, suggest the Jake M rock is an

Skye.[5] The Jake M rock is a ventifact with a volcanic fabric.[6] Its pyramidal shape was formed by eolian drifted grains of sand. The little cavities on its surface were formed by the blast-effect, which is caused by different flow dynamics at the micro-relief.[6] On the surface one could see the marks of the main wind direction, by which Jake M was formed.[6] On September 27, 2013, NASA scientists reported that Jake M rock was a mugearite and very similar to terrestrial mugearite rocks.[7][8][9][10]
