Selection of Critical Design Parameters for MMOD Protection in Interplanetary Missions This paper presents a methodology for the selection of critical design-parameters for the design of Micro Meteoroid and Orbital Debris (MMOD) spacecraft protection based on a modified implementation of the concept of the Probability of No Impact (PNI). The PNI methodology, based on Poisson s discrete statistics, has been widely used to determine critical particle sizes for the design of protection systems. However, it does not provide guidelines for the selection of the design impact speed, especially when the impact speed h ...

Use of hydrocode modeling to develop advanced MMOD shielding designs A multi-physics computations-based methodology for space debris hypervelocity impact (HVI) damage mitigation is presented. Specifically, improved debris mitigation through development of innovative, lightweight structural designs is described. The methodology has been applied to the design of the Solar Probe Plus (SPP) spacecraft to mitigate extreme solar microdust hypervelocity impacts (50-300 km/s) by the Johns Hopkins University Applied Physics Laboratory (JHU/APL). The methodology combines hydrocode computations of the c ...

A review of the Solar Probe Plus dust protection approach The Solar Probe Plus (SPP) spacecraft will go closer to the Sun than any manmade object has gone before, which has required the development of new thermal and micrometeoroid protection technologies. During the 24 solar orbits of the mission, the spacecraft will encounter a thermal environment that is 50 times more severe than any previous spacecraft. It will also travel through a dust environment previously unexplored, and be subject to particle hypervelocity impacts (HVI) at velocities much larger than anything previously e ...

Hyper velocity protection developments on the solar probe plus mission The Solar Probe Plus (SPP) spacecraft will go closer to the Sun than any manmade object has gone before. The mission includes both solar flux and micrometeoroid environments much more severe than anything experienced by previous spacecraft. As a result, new analytical and testing methodologies are being developed to ensure the success of the mission. One of the major efforts is the development of an analytical approach for hypervelocity impacts (HVI) at speeds up to 300 km/s. To date, this dust study has made several notable ...
