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?

The Next Step In Low-Cost Student Access to Space



34

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.

Proven concept:RockOn 2008/2009RockSat 2009

RockSat-W Standard:(March 2008)Mass StandardMOI StandardStreamline Integration Vibe/MOI not required



35

3.2 RockSat Payload Canister Structural

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

* RockSat Requirement, Workshop Canisters are a standard established in spring of 2008



36

3.3 RockSat Paylod Canister Integration

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

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



37

3.4 RockSat Payload Canister Electrical

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.

Activation Types:

• RockOn Style (Latching)• Command Line (Early Activation)
