RockOn and RockSat Payload Canister... A Sounding Rocket Payload Workshop and The Next Step In Low Cost Student Access To Space Colorado & Virginia Space Grant Consortium RockSat Presentation 23 June 2009
1.0 History “The story of RocketSat and its evolution to the Next How-To Workshop and Low Cost Student Access to Space and BEYOND!” 2.0 RockOn! “Where it all begins…” 3.0 RockSat-C “You’ve built our standard payload, come back and build a payload of your own… with some guidance and restrictions of course…” 4.0 RockSat-X “Is RockSat-C too easy? Too limited? How about full access to space? 0.0 Presentation Overview
1.0 History - The workshop kit or RocketSat has been under development and testing since January 2006 - RocketSat was developed by undergraduate students from the University of Colorado at Boulder - RocketSat has flown four times in different configurations - RocketSat I September 2006 - RocketSat II April 2007 - RocketSat III June 2007 - RocketSat D March 2008 (moved to June/July 2008) - RocketSat IV June 24, 2008
1.1 History: RocketSat I Objectives: 1. Easily reproducible payload design (COTS) 2. Qualitative data description of flight environment with altitude 3. Science Package: - Geiger Counter - Microwave Detector - Temperature sensor - Accelerometers - Pressure sensor
1.2 History: RocketSat II Objectives: 1. Easily reproducible payload design (COTS) 2. Record detailed flight data: - Video Camera 3. Environmental sensors: - Temperature - Pressure - Humidity - Three-axis accelerometers - Strain gauges - Faculty GPS experiment
1.3 History: RocketSat III The Third Time’s A Charm Objectives: 1. Re-fly all hardware from RS I except microwave sensor and Geiger counter 2. New Sensors: - Silicon pressure sensor - New Geiger counter - New microwave sensor
1.4 History: RocketSat-D Sanity Check RocketSat D (for Donut) Objectives 1. Sanity check for RockOn workshop kit

RockSat-C The Next Step In Low-Cost Student Access to Space
3.1 RockSat Payload Canister Established RockOn led to the development of the RockSat Payload Canister Standard Interface to Wallops Flight Facility’s Sub-SEM ring assembly. • RockSat-W Standard: • (March 2008) • Mass Standard • MOI Standard • Streamline Integration • Vibe/MOI not required Proven concept: RockOn 2008/2009 RockSat 2009 34
Highlights: • Each shall weight < 20* lbs with payloads and hardware • Sixteen (16) 8-32 Cap Head screw around split barrel • Five (5) 8-32 Cap Head screws on both top and bottom bulk heads, ten total. • CG shall lie within a 1X1X1” envelope centered on the geometric centroid of the canister. • WFF Interface: • - Wire-way to pass RBF/Command wires to Wallops Flight Facility 3.2 RockSat Payload Canister Structural * RockSat Requirement, Workshop Canisters are a standard established in spring of 2008
Highlights: • Cans designed to be easily integrated onto Wallops Flight Facility’s Sub-SEM ring assembly • Integration of five cans (left) to Sub-SEM ring assembly successful during RockOn 2008/2009 and RockSat 2009 • WFF Interface: • Twelve (12) 8-32 Cap Head screws attach canister to Sub-SEM rings. • Bolt circle: = 10.8” • 8-32 socket cap head screws 3.3 RockSat Paylod Canister Integration
Activation Types: • RockOn Style (Latching) • Command Line (Early Activation) • Two Key Requirements: • 0.SYS.1 All payloads shall be designed such that Wallops will always know its status as active or inactive (current flowing/not flowing). 1.SYS.1 Payloads wishing to activate early shall be designed such that Wallops can activate and deactivate the payload or subsections of the payload via a single set of RBF wires. 1.SYS.2 Payloads wishing to activate at launch shall be designed with two opens in the system such that activation occurs if and only if Wallops has closed the RBF connection and the G switch has been depressed. 3.4 RockSat Payload Canister Electrical
Metropolitan State College University of North Dakota Colorado State University 10 Universities from across the United States sent payloads to just over 72 miles on June 26, 2009! PL1 PL2 PL3 PL4 PL5 PL6 PL7 PL8 PL9 3.5 Who Flew in 2009?
