Newswise — Arizona State University has been selected by NASA to design, deliver and oversee the Mastcam-Z imaging investigation, a pair of color panoramic zoom cameras, on the next rover mission to be launched to the surface of Mars in 2020. Jim Bell, a professor in ASU’s School of Earth and Space Exploration, will be the principal investigator overseeing the investigation.
NASA has selected the instruments that will be carried aboard the Mars 2020 mission, a roving laboratory based on the highly successful Curiosity rover. The instruments were competitively selected from 58 proposals submitted, two times the average number of proposals submitted for instrument competitions in the recent past and an indicator of the extraordinary interest in exploration of the Red Planet.
The Mars 2020 rover will be designed to seek signs of past life on Mars, to collect and store samples that could be returned to Earth in the future, and to test new technology to benefit future robotic and human exploration of Mars. The instruments onboard will help to build upon the many discoveries from the Curiosity Mars rover and the two Mars Exploration Rovers (Spirit and Opportunity) and will be the critical next step in NASA’s strategic program of exploring the Red Planet.
Bell will oversee an international science team responsible for creating and operating the cameras on NASA’s next, yet-to-be-named, Mars rover. Bell has been responsible for the science imaging systems onboard the NASA Mars Exploration Rovers Spirit and Opportunity, and is the deputy P.I. of the color cameras on the Curiosity rover.
“These cameras will be the main eyes of NASA’s next rover,” says Bell.
The imaging system ASU will deliver is a pair of multispectral, stereoscopic cameras that will be an enhanced descendant of Curiosity’s successful imaging instrument called Mastcam. Mastcam-Z will be comprised of two zoom camera heads to be mounted on the rover’s remote sensing mast. This matched pair of zoom cameras will each provide broad-band red/green/blue (RGB) color imaging, as well as narrow-band visible to short-wave near-infrared multispectral capability.
Mastcam-Z will have all of the capabilities of Curiosity’s imaging instrument, but is augmented by a 3.6:1 zoom feature capable of resolving features about 1 millimeter in size in the near field and about 3-4 centimeters in size at 100 meter distance.
“The cameras that we will build and use on Mars are based on Curiosity’s cameras but with enhanced capabilities,” explains Bell. “Specifically we will be able to use our zoom capability to allow us to play a much more significant role in rover driving and target selection.”
Mastcam-Z’s imaging will permit the science team to piece together the geologic history of the site—the stratigraphy of rock outcrops and the regolith, as well as to constrain the types of rocks present. The cameras will also document dynamic processes and events via video (such as dust devils, cloud motions, and astronomical phenomena, as well as activities related to driving, sampling, and caching), observe the atmosphere, and contribute to rover navigation and target selection for investigations by the coring/caching system, as well as other instruments.
Bell’s large international science team will include Mark Robinson, School of Earth and Space Exploration professor and principal investigator for the imaging system on board NASA’s Lunar Reconnaissance Orbiter Camera. Robinson brings significant experience in planetary geology and spacecraft imaging and will be responsible for characterizing the regolith from Mastcam‐Z images and assisting with camera calibration and mission operations.
In addition, Bell intends to involve a significant number of staff, undergraduate students, and graduate students in the mission. For example, SESE Research Scientist Craig Hardgrove and Technology Support Analyst Austin Godber are slated to play leading roles in the design, testing, and operations of the Mastcam-Z investigation.
Mastcam-Z remote instrument operations will be directed from the ASU Science Operations Center (SOC), housed in the Mission Operations Center located in the Interdisciplinary Science and Technology Building IV on the ASU campus. ASU faculty, staff, and students will work closely with mission engineering leads at NASA's Jet Propulsion Laboratory in Pasadena, Calif.
“We are very excited about playing such a critical role in NASA’s next Mars rover. And we are especially excited because this rover will be the first step in NASA’s Mars rover sample return mission,” says Bell. “We are eager are to play a role in the selection of the first Martian samples for eventual return to Earth.”
