Mars Exploration Mission Enhances Data Efficiency through Compressing Images

The Sol 26 drive was successful and post-drive images revealed interesting outcrops in front of the rover. As ChemCam was operational again, the focus of Sol 27’s plan was on sampling Mars’ atmosphere with the SAM instrument. However, upon discovering a new outcrop target, the science team wanted to investigate further with ChemCam’s laser. Steve Squyres, the Mineralogy Science Theme Group Lead, requested an additional 40 minutes for scientific observations.

Pauline Hwang, the Tactical Uplink Lead agreed and granted the team extra time for their work. This decision was met with happiness and Mastcam observations were included in the plan. I left JPL a few hours ago and it seemed likely that these observations would be approved and sent to MSL early the next morning. Although I wasn’t scheduled for a tactical role that day, I couldn’t resist spending most of my time at JPL as I find MSL mission operations to be incredibly engaging. With less focus on planning, I was able to catch up on tasks such as processing new MARDI images for compression analysis and reviewing older ChemCam RMI images for size reduction potential.

Compressing images is crucial for maximizing data transmission efficiency from MSL to Mars orbiters. It is essential to preserve image details for geological interpretation while optimizing file sizes. The analysis of compressing images is vital for ensuring efficient data transmission and utilization of resources.
