Curiosity: Update 4 – Pyramid Rock

Pyramid rock: “Jake Matijevic”

On September 19, 2012, NASA scientists assigned Mars rover Curiosity a monumental task — determine the properties of a football-sized pyramid-shaped rock that looks like the Great Pyramid of Giza. Strange thing is… the rock is in the middle of nowhere! Where did it originate? Could it have been built by an intelligent race that lived or still lives on Mars? Curiosity discovered this rock at the end of its 43rd Martian day. Using the 10 cm tall and 16 cm wide rock as a practice target, Curiosity will test its contact instruments: Alpha Particle X-Ray Spectrometer for reading a target’s elemental composition and  Mars Hand Lens Imager for close-up imaging. While weird rocks shaped by wind erosion are not uncommon on Mars’ surface, this minature pyramid is probably just a rock. Spurring the imaginations of Earthlings imagining life beyond, the odd rock remains the center of speculation, especially since Curiosity’s objective is to find evidence of Mars’ capability to harbor life. Named after NASA engineer Jake Matijevic who passed away on August 20, 2012, the pyramid-shaped rock may be a impact fragment ejected into the Gale Crater. Jake Matijevic was the leading engineer in the Sojounrer, Opportunity, and Spirit missions, while surface operations systems chief engineer for the Mars Science Laboratory/ Curiosity mission.

Curiosity’s robotic arm

On September 22, 2012, Curiosity finished its inspection of the rock target. Its ChemCam lasers zapped the rock to analyze its chemical components and calibrate the instruments, marking the first use of Curiosity’s robotic arm.
