NASA Independent Verification and Validation Lessons Learned
on the Mars Exploration Rover

NASA Independent Verification and Validation (IV&V) Facility

 

Abstract

The NASA Independent Verification and Validation (IV&V) Facility has been in operation for just over 10 years now, but it was only recently (2000) that the scope of the Facility was changed to support more Earth orbiting and interplanetary robotic missions. One of the first interplanetary missions to have IV&V performed was the Mars Exploration Rover (MER) mission that launched two rovers to Mars in mid-2003 with their landings in early 2004. This paper will discuss the generic approach to performing IV&V on a NASA mission and also the tailoring process for NASA IV&V on the MER mission. It will then discuss the issues and problems encountered while performing the IV&V analysis. It will also review the software anomaly that occurred on the Spirit rover and the IV&V Facility's analysis in that area.
