Cyclops Splinter With SpinSat and Lonestar

Cyclops Splinter With SpinSat and Lonestar Cyclops provides the ISS Program with a method to transfer internally stowed satellites to the external environment. Cyclops provides a structural platform for orienting and mechanically deploying deployable payloads robotically from the ISS. The Cyclops payload will become an on-orbit facility that can be utilized by deployable payloads for deployment from ISS. Deployable payloads can be delivered to ISS, stowed on-board, and then deployed through the Japanese Experiment Module (JEM) Airlock via Cyclops. After deployment, they begin operations as an independent small satellite or spacecraft orbiting in space with command and support from ground stations independent of ISS mission control.

Cyclops Splinter With SpinSat and Lonestar Experiment Attachment Fixture Standard interface between satellites and Cyclops. Keyed to insure proper orientation of satellite on Cyclops (matches cutout in the Cyclops Pusher Plate). Interfaces with the Payload Retention Mechanism on Cyclops to secure the satellite until deployment.

Cyclops Splinter With SpinSat and Lonestar Payload Retention Mechanism Mounted to Cyclops structure underneath the Pusher Plate. Secures satellite to Cyclops until deployment. Used by IVA crew to secure the satellite to Cyclops. Experiment Attachment Fixture (EAF) Finger, 3X Experiment Inhibit Switch Contact Zone Payload Retention Mechanism Rotate CCW to open Fingers Rotate CW to close Fingers

Verifies that the Payload Retention Mechanism fingers are in the “over center” position on the cam, indicating that the satellite is secure to Cyclops. Red color on gauge shaft is a visual indicator of cam position (no red showing = secure)

Cyclops Splinter With SpinSat and Lonestar SpinSat is the first satellite to use the Cyclops system. Objective is to provide a test platform to demonstrate and characterize the Electrically- controlled Solid Propellant (ESP) in space, test the Space Surveillance Network’s (SSN) detection and characterization capabilities, provide an atmospheric drag experiment during a more active solar period. Spherical 22” diameter spacecraft is fitted with retroreflectors for satellite laser ranging. Total of 72 ESPs to control spin. SpinSat overview

Cyclops Splinter With SpinSat and Lonestar Safe, Test, and Arm Plugs Safe Plug installed for launch and on orbit stowage. Held in place with retaining ring. Test Plug installed by crew prior to mounting SpinSat onto Cyclops. Verifies inhibits are in place. Inhibit switches located at the Experiment Attachment Fixture (interface with Cyclops). Removed after SpinSat mounted onto Cyclops and inhibits verified. One spare is flying. Arm Plug installed after inhibits are verified and arms the satellite systems to turn on when SpinSat is released. Final inhibit is removed by ground command after deployment.

Crew will visually verify final seating of fasteners Review of crew procedure inputs for proper torque values and visual cues. Cyclops-F03 1. Cyclops fails to deploy experiment nominally due to primary spring/Pusher Plate/Scissor assembly anomaly. 1.4 IVA operations: The IVA crew will set the proper preload on the primary deployment spring by tightening the Preload Assembly while monitoring the visual indicator position for the correct setting. Note: reference experiment specific hazard report to determine correct preload setting Review of crew procedure inputs for steps to set proper preload on the Primary Deployment Spring. 2. Cyclops/generic experiment assembly is in an indeterminate structure state due to the Cam Retention Finger not retracting completely. 2.3 EVR operations: The IVA crewmember or ground operator will monitor the JEM SFA or SPDM number of turns and torque (TBD/TBD) to ensure the appropriate revolutions to deploy is achieved Review of crew procedure inputs for proper revolutions and torque values.
