This driving tool, called visual odometry, allows the rover to use images of landscape features to determine if it has traveled as far as predicted, or if its wheels have slipped.

"The purpose of the pattern is to create features in the terrain that can be used to visually measure the precise distance between drives," said Matt Heverly, the lead rover driver for Curiosity at JPL.

The pattern is Morse code for JPL, the abbreviation for NASA's Jet Propulsion Laboratory in Pasadena, Calif., where the rover was designed and built, and the mission is managed. Careful inspection of the tracks reveals a unique, repeating pattern, which the rover can use as a visual reference to drive more accurately in barren terrain.
22, 2012, and beamed back pictures of its accomplishment in the form of track marks in the Martian soil. Since touchdown, Curiosity journeyed more than 23 km (14 miles), drilling 26 rock samples and scooping six soil samples.NASA's Curiosity rover took its first test stroll Wednesday Aug. (x) the Mars Science Laboratory Entry Descent and Landing Instrument (MEDLI) measured the heating and atmospheric pressure changes that occurred during the descent to help determine the effects on different parts of the spacecraft. (ix) the Rover Environmental Monitoring Station (REMS) contains all the weather instruments needed to provide daily and seasonal reports on meteorological conditions around the rover (viii) the Dynamic Albedo of Neutrons (DAN) looks for telltale changes in the way neutrons released from Martian soil that indicate liquid or frozen water exists underground (vii) the Radiation Assessment Detector (RAD) is helping prepare for future human exploration of Mars the instrument measures the type and amount of harmful radiation that reaches the Martian surface from the Sun and space sources (vi) the Sample Analysis at Mars (SAM) is made up of three different instruments that search for and measure organic chemicals and light elements that are important ingredients potentially associated with life (v) the Chemical and Mineralogy (CheMin) performs chemical analysis of powdered rock samples to identify the types and amounts of different minerals that are present (iv) the Chemistry and Camera (ChemCam) instrument’s laser, camera and spectrograph work together to identify the chemical and mineral composition of rocks and soils (iii) when the Alpha Particle X-Ray Spectrometer (APXS) is placed right next to a rock or soil surface, it uses two kinds of radiation to measure the amounts and types of chemical elements that are present. (ii) the Mars Descent Imager (MARDI) shot a color video of the terrain below as the rover descended to its landing site the video helped mission planners select the best path for Curiosity when the rover started exploring Gale Crater (i) the Mars Hand Lens Imager (MAHLI) is the rover’s version of the magnifying hand lens that geologists usually carry with them into the field MAHLI’s close-up images reveal the minerals and textures in rock surfaces The drill holes were taken by the MAHLI camera on the end of the rover’s robotic arm. A map in the upper left shows where the holes were drilled along the rover’s route, along with where it scooped six samples of soil. These 26 holes represent each of the rock samples NASA’s Curiosity Mars rover has collected as of early July 2020. Its large size allows it to carry an advanced kit of science instruments, including 17 cameras, a laser to vaporize and study small pinpoint spots of rocks at a distance, and a drill to collect powdered rock samples: The car-size rover is about as tall as a basketball player and uses a 2.1-m- (7-foot) long arm to place tools close to rocks selected for study. The mission is led by NASA’s Jet Propulsion Laboratory, and involves almost 500 scientists from the United States and other countries around the world.Ĭuriosity explores the 154-km- (96-mile) wide Gale Crater and acquires rock, soil, and air samples for onboard analysis.

The rover drilled twice in this location, nicknamed Glen Etive. Curiosity rover took this selfie on October 11, 2019.
