Mission Overview • Utilize Nitric Oxide sensor for NO concentration data collection in high altitudes – – IMU data to accompany NO data Optimal senor orientation Successful data transmission and storage Mechanical and thermal securing for reentry • Successful implementation of Piezo Dust Detector and collection of space dust impact energy readings for Baylor University – Optimal sensor orientation – Successful data transmission and storage – Mechanical and thermal securing for reentry 2012 Co. DR 4

Mission Overview: Theory and Concepts • Nitric Oxide (NO) sensor – Measure concentration of NO as a function of altitude – Flight heritage in Rock. Sat-C (NOIME) • Piezo Dust Detector (PDD) – Collect measurements of velocity and energy from incoming dust particles – Existing flight heritage on UT satellite 2012 Co. DR 5

Mission Overview: Theory and Concepts (PDD) 2012 Co. DR 6

Mission Overview: Mission Requirements • Project requirements – The system shall conform to the requirements set forth in the 2011 Rock. Sat-X User Guide – System shall meet power transmission requirements to sensors – System shall transmit data via NASA Wallops telemetry – System should orient NO sensor for optimal data collection – System shall collect data from PDD sensor – System should mechanically and thermally secure sensors and integral components for reentry and recovery • Minimum success criteria – NO data should be consistent with current global models – Shall gain flight heritage for PDD sensor crestock. com 2012 Co.

Preliminary Con. Ops (for Terrier-Orion) Altitude t ≈ TBD Altitude: ~100 km t ≈ 4. 0 min PDD On Altitude: 95 km t ≈ TBD Altitude: TBD Apogee Skirt Released t ≈ 2. 8 min Engage Reentry Shield Altitude: ≈115 km t ≈ 4. 5 min Altitude: 75 km Reentry End of Orion Burn t ≈ 0. 6 min t ≈ 5. 5 min Altitude: 52 km t = 0 min Chute Deploys -G switch triggered t ≈ 15 min -NO and IME sensors on Splash Down -Begin data collection 2012 Co.

Mission Overview: Expected Results • Nitric Oxide concentrations in high altitude • Correlating to Dr. Bailey’s preliminary data • Compare to NOIME results • Will get clarification from Dr. Bailey on expected results • Energy and velocity readings of dust particles in space • Correlating to Baylor University’s preliminary data • Will get clarification from Baylor University on expected results 2012 Co. DR 9

Design Overview • Utilizing NO sensor and IMU from NOIME (Rock. Sat-C flight heritage) – NO sensor collects wavelength data around 220 nm – IMU collects acceleration, angular rate, and magnetic field data • Collecting space dust velocity and energy with PDD – Little flight heritage 2012 Co. DR 10

FBD – Mechanical System (rough diagram) 2012 Co. DR 12

Design Overview: Rock. Sat-X 2011 User’s Guide Compliance • Mass Estimate – Same instruments as NOIME plus PDD – Will work with UW to keep from exceeding mass constraint • No expectation of exceeding allotted physical space requirements • No deployables or booms expected • All telemetry lines (asynchronous, parallel, and 10 bit 0 -5 V A/D) will have to be shared with UW • Will likely use two power/timer lines – PDD should be powered on sometime after launch (NO probe has no known constraint) • Since this payload will share a power and telemetry lines with UW, will work with UW’s constraints to divide utilities efficiently for both projects • CG requirements – Will restrict the CG to within 1 inch of the center of the deck • May need to use batteries for extra power – TBD 2012 Co. DR 13

Design Overview: Shared Can Logistics • Payload area will be shared with UW – The Astro. X team strives to test an electrically active heat shield prototype • Plan for collaboration – Team leads will stay in contact via email – Solidworks models, mass budgets, power budgets, etc. will be shared through a drop box account 2012 Co.

Management - Preliminary Schedule for the Semester 2012 Co. DR 16

Management • Monetary budget – Most components are being used from last year’s Rock. Sat-C mission – Free in-house shop time at VT – Other components TBD • Team mentors – Dr. Kevin Shinpaugh – Dr. Troy Henderson – Dr. Scott Bailey 2012 Co. DR 17

Conclusion • This mission will provide useful data of NO concentration in the upper atmosphere and velocity and energy of dust particles in space – Will also provide flight experience to these two sensors • Must work closely with UW and work within their mission constraints since they are further along in the design process • Way forward – Investigate power and data storage/transmission needs for all known components and sensors 2012 Co.
