Mission Overview
To design and build a standardized probe deployment system to test advanced reentry concepts including guided reentry and electrically active heat shielding.
These concepts as well as a standardized delivery mechanism will provide a foundation to build future experiments.
4
Systems Overview
Probe Ejection System (PES) “PEZ” Ejects probes and supports their flight with
telemetry. Advanced Heat Shield System (AHSS)
“OZ” Uses electrically active systems to reduce
heat during reentry. Guided Reentry System (GRS)
Attempts to maneuver the probe to an environment that makes recovery easier and more cost effective.
5
Scientific Objectives
oCharacterize the performance of electrically active methods of reentry.
oProposed methods of reentry: oMagnetic ShieldoPlasma Shield
6
Purpose of Reentry Methods
Create a lighter weight heat shield system than current passive methods.
Create a high performance heat shield that reduces heat more than passive methods.
Establish a re-useable heat shielding system.
Reduce cost. Simplify aerodynamic design
requirements. Establish robust and reliable heat shield
system.
7
Details of Potential Reentry Methods
Magnetic Shield:Utilize magnetic system to increase the buffer zone between the surface of the payload and the plasma generated during reentry.
Plasma System:Establish a continuous shockwave ahead of the payload that will cause the plasma generated during reentry to divert around the payload also increasing the buffer zone.
8
Engineering Objectives
o Develop standardized probe and deployment system.
o Develop alternative sample return methods.
o Develop a reliable and reusable standard electronic system.
9
Success Criteria
Reduce heat on reentry of a probe. Confirm results with control probe. Successfully recover control probe. Create a standardized probe
deployment platform enabling future progression in the field.

Circuits initialize and begin collecting and transmitting data.
Probes starts up and begins transmitting.
Rocket skins are shed, probes are deployed..
Power and telemetry is shut down and data collection and transmission ceases. Splashdown.
Probe chutes are deployed. Radio signal is reacquired and data is transmitted back to Wallops and backed up on the base station.
Radio blackout. Probes activate and sample temperature data during reentry.
T = 0 min.
T = 1.3 min.
T = 2.8 min.
T = 4.5 min.
T = 5.5 min.
T = 15 min.
