Curiosity: Update 6 – Jake Matijevic, the Martian Rock

Analyzing “Jake Matijevic”

Curiosity first discovered “Jake Matijevic,” the pyramid rock on Mars, on September 19, 2012, but on October 11, 2012, NASA released a report on the chemical composition of this unusual rock. The rock’s composition was more varied than expected and even resembled some rocks in Earth’s interior. The pyramid rock resembles the common igneous rock found in many volcanic areas on Earth. On Earth, these igneous rocks typically form in the mantle from the crystallization (solidification) of liquid magma at elevated pressure. The first rock analyzed by the rover’s arm-mounted Alpha Particle X-Ray Spectrometer (APXS) and the thirtieth by the rover’s Chemistry and Camera instrument (ChemCam) on September 22, 2012, “Jake” has unique compositions at all 14 points targeted by Curiosity. Analyzing “Jake” marked the first time results of ChemCam were compared with APXS. In addition to the two instruments, Curiosity carries analytical laboratories to provide a more in-depth view of rocks’ and powders’ compositions.

Curiosity’s first scoop of sample from “Rocknest” was perfect. The first scoop is designed to clean Curiosity, essentially like a Martian car wash. Curiosity will spend three weeks at” Rocknest” and then drive 100 yards east to select a rock as its first target for its drill.

  1. This is fascinating on several levels Tina, the ability of the remote unit to not only do in-depth mineral composition analysis but also to self clean, just excellent.

    • Mmhmm, not only that, Curiosity has also discovered some very interesting things about Mars. It keeps finding these weird rocks and minerals and even found that Mars has lost over half its original atmosphere!
