EDSN A.2.1.EDSN.ODAR Orbital Debris Assessment Report (ODAR) Rev A Assessment Report Format: ODAR Technical Sections Format Requirements: This ODAR follows the format in NASA-STD-8719.14, Appendix A.1 and includes the content indicated at a minimum in each section 2 through 8 below for the EDSN satellite. Sections 9 through 14 apply to the launch vehicle ODAR and are not covered here. EDSN ODAR Section 1: Program Management and Mission Overview Mission Directorate: Office of Chief Technologist (OCT) Program Executive: Andrew Petro, HQ Program/project manager: Bruce Yost, Program, ARC / Stephan Ord, Project, ARC Senior Management: Dave Korsmeyer, ARC Foreign government or space agency participation: None. Summary of NASA’s responsibility under the governing agreement(s): None. Schedule of upcoming mission milestones: FRR: June, 2013 Launch: September, 2013 Mission Overview: The EDSN mission is a group of eight 1.5U CubeSats that will launch as secondary payloads on the ORS-4 mission. A 1.5U CubeSat measures 10 cm x 10 cm x 15 cm in size, according to the CalPoly CubeSat specifications. Each weighs approximately 1.7kg. All eight satellites are identical. EDSN is a technology demonstration of a swarm of eight low-cost CubeSats in Low Earth Orbit (LEO) with advanced cross-link and downlink communications capability, suitable as a platform for Space Weather or other science applications requiring geographically distributed, synchronized data acquisition. Each unit has identical hardware and software. The mission operations phase is planned to be 60 days. All eight EDSN satellites are shipped to ORS facilities in Albuquerque to be integrated with the ORS-4 launch vehicle – a Super Strypi procured by ORS from Sandia National Labs. The eight EDSN satellites will be stowed in NASA NLAS dispensers that eject the satellites upon pre-set sequence controlled by the launch vehicle. Once ejected by the launch vehicle, the eight EDSN satellites will operate in the same elliptical orbit. The satellites have no propulsion systems, and therefore no station-keeping. The mission ends with natural atmospheric reentry of all eight satellites within 820 days from launch (see ODAR Section 6). Launch vehicle and launch site: Super Strypi, Kauai Test Facility, Hawaii.

EDSN A.2.1.EDSN.ODAR Orbital Debris Assessment Report (ODAR) Rev A Proposed launch date: 09/2013 Mission duration: 60 Days in LEO operations. Launch and deployment profile, including all parking, transfer, and operational orbits with apogee, perigee, and inclination: EDSN is a secondary payload on the ORS-4 mission. The ORS-4 Super Strypi will launch into an elliptical orbit. All spacecraft will be deployed with a small delta-V in the plane normal to the launch vehicle upper stage final velocity vector. The deployment pattern will be such that NLASS deployment mechanisms will simultaneously eject 2 spacecraft on opposing sides of the launch vehicle upper stage, with a 30 second delay until the ejection of the remaining 4 spacecraft on opposing sides of the upper stage.. The nominal elliptical orbit will be: Apogee: 525 km Perigee: 450 km Inclination: 97 degrees. The EDSN satellites have no propulsion and therefore do not actively station keep. There is no parking or transfer orbit. ODAR Section 2: Spacecraft Description Physical description of the spacecraft: The EDSN mission consists of eight satellites. Each satellite is a standard 1.5U CubeSat form factor, 10cm x 10cm x 15cm. Each weighs approximately 1.7kg. Each satellite has four Lithium-Ion batteries. Solar panels cover all 6 faces for battery charging. None of the satellites have titanium parts. During the 60 day mission, each satellite in the network will use an average of 1.1 Watts. Following the 60-day mission, the satellites will be commanded to deplete the batteries by turning on all subsystems. Each satellite has a short “tape measure” antenna, about 6 inches in length, deployed 30 minutes after the launch vehicle ejects the satellites into orbit. The tape-measure antenna is the only protrusion from the flat faces of the satellites (see Figure 2 below). Once this document has been printed it will be considered an uncontrolled document.

EDSN A.2.1.EDSN.ODAR Orbital Debris Assessment Report (ODAR) Rev A Identification, including mass and pressure, of all fluids (liquids and gases) planned to be on board and a description of the fluid loading plan or strategies, excluding fluids in sealed heat pipes: None Fluids in Pressurized Batteries: None. The EDSN satellites use unpressurized standard COTS Lithium-Ion battery cells. Description of attitude control system and indication of the normal attitude of the spacecraft with respect to the velocity vector: All of the EDSN satellites have active three-axis attitude control by means of three orthogonal reaction wheels and three orthogonal sets of two magnetorquer coils. The EDSN satellites have three-axis attitude determination. The satellites are rectangular in shape consistent with 1.5U standard (10cmx10cmx15cm) – the four side surface areas (15cm x 10cm) are identical and the two end surface areas are identical (10cm x 10cm). When passing over ground station at Santa Clara University at approx. 37.3 degrees N Lattitude121.9 degrees W Longitude, the satellites will be oriented with one square side pointed nadir. At other times, when communicating within the constellation, the satellites square side will be oriented at right angles to nadir. During scheduled periods of no active attitude control, the satellite will orient itself for minimal drag. Note for purposes of atmospheric re-entry modeling (Sect 6.4 of this report) a random attitude orientation is modeled. Description of any range safety or other pyrotechnic devices: No pyrotechnic devices are used. Description of the electrical generation and storage system: Standard COTS Lithium-Ion battery cells are charged before payload integration and provide electrical energy during the mission. For all EDSN satellites, the battery holder and protection circuit is a COTS item designed for the Lithium-Ion 18650 cell format batteries. For all EDSN satellites, the solar panels and charging circuit recharge the batteries. All EDSN satellites carry 4 Lithium-Ion battery cells in the 18650 cell format. Identification of any other sources of stored energy not noted above: None. Identification of any radioactive materials on board: None.

EDSN A.2.1.EDSN.ODAR Orbital Debris Assessment Report (ODAR) Rev A ODAR Section 3: Assessment of Spacecraft Debris Released during Normal Operations Identification of any object (>1 mm) expected to be released from the spacecraft any time after launch, including object dimensions, mass, and material: There are no intentional releases. Rationale/necessity for release of each object: N/A. Time of release of each object, relative to launch time: N/A. Release velocity of each object with respect to spacecraft: N/A. Expected orbital parameters (apogee, perigee, and inclination) of each object after release: N/A. Calculated orbital lifetime of each object, including time spent in Low Earth Orbit (LEO): N/A. Assessment of spacecraft compliance with Requirements 4.3-1 and 4.3-2 (per DAS v2.0.1) 4.3-1, Mission Related Debris Passing Through LEO: COMPLIANT 4.3-2, Mission Related Debris Passing Near GEO: COMPLIANT ODAR Section 4: Assessment of Spacecraft Intentional Breakups and Potential for Explosions. Potential causes of spacecraft breakup during deployment and mission operations: There is no credible scenario that would result in spacecraft breakup during normal deployment and operations. Summary of failure modes and effects analyses of all credible failure modes which may lead to an accidental explosion: In-mission failure of a battery cell protection circuit could lead to a short circuit resulting in overheating and a very remote possibility of battery cell explosion. The battery safety systems discussed in the FMEA (see requirement 4.4-1 below) describe the combined faults that must occur for any of seven (7) independent, mutually exclusive failure modes to lead to explosion. The rationale is true for all batteries onboard the spacecraft. There is no credible scenario in which the reaction wheel energy would exceed the breakup/explosion energy required for the reaction wheel material to breakup/explode. The supporting analysis is described in the FMEA below. Detailed plan for any designed spacecraft breakup, including explosions and intentional collisions: There are no planned breakups.

EDSN A.2.1.EDSN.ODAR Orbital Debris Assessment Report (ODAR) Rev A List of components which shall be passivated at End of Mission (EOM) including method of passivation and amount which cannot be passivated: The EDSN satellites incorporate logic in the watchdog to turn on all subsystems at the completion of the mission to discharge the batteries. Ground tests indicate that the battery packs will be completely discharged within 3 days of turning on all subsystems. Rationale for all items which are required to be passivated, but cannot be due to their design: There are no items that require passivation that , but cannot happen due to design. Assessment of spacecraft compliance with Requirements 4.4-1 through 4.4-4: Requirement 4.4-1: Limiting the risk to other space systems from accidental explosions during deployment and mission operations while in orbit about Earth or the Moon: For each spacecraft and launch vehicle orbital stage employed for a mission, the program or project shall demonstrate, via failure mode and effects analyses or equivalent analyses, that the integrated probability of explosion for all credible failure modes of each spacecraft and launch vehicle is less than 0.001 (excluding small particle impacts) (Requirement 56449). Compliance statement: Required Probability: 0.001. Expected probability: 0.000. Supporting Rationale and FMEA details: Battery explosion: Effect: All failure modes below might result in battery explosion with the possibility of orbital debris generation. However, in the unlikely event that a battery cell does explosively rupture, the small size, mass, and potential energy, of these small batteries is such that while the spacecraft could be expected to vent gases, most debris from the battery rupture should be contained within the vessel due to the lack of penetration energy. The rationale is true for all batteries onboard the spacecrafts. Probability: Very Low. It is believed to be less than 0.1% given that multiple independent (not common mode) faults must occur for each failure mode to cause the ultimate effect (explosion). Failure mode 1: Internal short circuit. Mitigation 1: Complete shock, vibration, thermal cycling, and vacuum tests followed by functional testing of the satellite to prove that no internal short circuit sensitivity exists. Once this document has been printed it will be considered an uncontrolled document. Page 10 of 84

EDSN A.2.1.EDSN.ODAR Orbital Debris Assessment Report (ODAR) Rev A Combined faults required for realized failure: Environmental testing AND functional tests must both be ineffective in discovery of the failure mode. Failure Mode 2: Internal thermal rise due to high load discharge rate. Mitigation 2: Cells were tested in lab for high load discharge rates in a variety of flight like configurations to determine if the feasibility of an out of control thermal rise in the cell. Cells were also tested in a hot environment to test the upper limit of the cells capability. No failures were seen. COTS 18650 lithium ion cells incorporate several features to protect against thermal runaway. First, they include a Positive Temperature Coefficient (PTC) polyswitch device that reduce current if temperature rises excessively. Second, these batteries should have a Current Interrupter Device (CID) which will disconnect the battery on overpressure and vent. Combined faults required for realized failure: Spacecraft thermal design must be incorrect AND external over current detection and disconnect function must fail to enable this failure mode, AND battery PTC and CID devices must fail to enable this failure mode. Failure Mode 3: Excessive discharge rate or short circuit due to external device failure or terminal contact with conductors not at battery voltage levels (due to abrasion or inadequate proximity separation). Mitigation 4: This failure mode is negated by a) design of battery packs and insulators such that no contact with nearby board traces is possible without being caused by some other mechanical failure, b) use of the COTS battery protection circuit on the battery holder for the 18650 cell format Lithium-Ion batteries, c) obviation of such other mechanical failures by proto-qualification and acceptance environmental tests for (shock, vibration, thermal cycling, and thermal-vacuum tests). Combined faults required for realized failure: An external load must fail/short-circuit AND external over-current detection and disconnect function, AND battery PTC and CID devices must all fail to result in this failure mode. Failure Mode 4: Inoperable vents. Mitigation 5: Battery vents are not inhibited by the battery holder design or the spacecraft. Combined effects required for realized failure: The manufacturer fails to install proper venting. Failure Mode 5: Crushing. Mitigation 6: This mode is negated by spacecraft design. There are no moving parts in the proximity of the batteries. Combined faults required for realized failure: A catastrophic failure must occur in an external system AND the failure must cause a collision sufficient to crush the batteries leading to an internal short circuit AND the satellite must be in a naturally sustained orbit at the time the crushing occurs. Once this document has been printed it will be considered an uncontrolled document. Page 11 of 84

EDSN A.2.1.EDSN.ODAR Orbital Debris Assessment Report (ODAR) Rev A Failure Mode 6: Low level current leakage or short-circuit through battery pack case or due to moisture-based degradation of insulators. Mitigation 7: These modes are negated by a) battery holder/case design made of non- conductive plastic, and b) operation in vacuum such that no moisture can affect insulators. Combined faults required for realized failure: Abrasion or piercing failure of circuit board coating or wire insulators AND dislocation of battery packs AND failure of battery terminal insulators AND failure to detect such failures in environmental tests must occur to result in this failure mode. Failure Mode 7: Excess temperatures due to orbital environment and high discharge combined. Mitigation 8: The spacecraft thermal design will negate this possibility. Thermal rise has been analyzed in combination with space environment temperatures showing that batteries do not exceed normal allowable operating temperatures which are well below temperatures of concern for explosions. Combined faults required for realized failure: Thermal analysis AND thermal design AND mission simulations in thermal-vacuum chamber testing AND over-current monitoring and control must all fail for this failure mode to occur. Reaction wheel breakup/explosion: There is no credible scenario that would result in the reaction wheels to breakup during normal deployment and operations. Each of the three reaction wheels are COTS with a moment of inertia of 81e-06 kg.m^2 and a maximum spin rate of 7000 RPM. The subsequent maximum stored energy in the Reaction Control System is 21.8 Joules; which is substantially less than the breakup/explosion energy required for a reaction wheel assembly breakup leading to material ejection. In addition, the Reaction Control System is encased by both the satellite shell and the solar panels. Requirement 4.4-2: Design for passivation after completion of mission operations while in orbit about Earth or the Moon: Design of all spacecraft and launch vehicle orbital stages shall include the ability to deplete all onboard sources of stored energy and disconnect all energy generation sources when they are no longer required for mission operations or post mission disposal or control to a level which can not cause an explosion or deflagration large enough to release orbital debris or break up the spacecraft (Requirement 56450). Compliance statement: The batteries in the satellite will discharge and burn up upon de-orbit. Once this document has been printed it will be considered an uncontrolled document. Page 12 of 84

EDSN A.2.1.EDSN.ODAR Orbital Debris Assessment Report (ODAR) Rev A 6.4 Assessment of spacecraft compliance with Requirements 4.6-1 through 4.6-5 (per DAS v 2.0.1 and NASA-STD-8719.14 section): Requirement 4.6-1. Disposal for space structures passing through LEO: A spacecraft or orbital stage with a perigee altitude below 2000 km shall be disposed of by one of three methods: (Requirement 56557) a. Atmospheric reentry option:  Leave the space structure in an orbit in which natural forces will lead to atmospheric reentry within 25 years after the completion of mission but no more than 30 years after launch; or  Maneuver the space structure into a controlled de-orbit trajectory as soon as practical after completion of mission. b. Storage orbit option: Maneuver the space structure into an orbit with perigee altitude greater than 2000 km and apogee less than GEO - 500 km. c. Direct retrieval: Retrieve the space structure and remove it from orbit within 10 years after completion of mission. Analysis: The EDSN satellites reentry is COMPLIANT using method “a.”. The EDSN satellites will be left in a 440 km, 524 km elliptical orbit, reentering in 820 days after launch with orbit history as shown in Figure 3 (analysis assumes an approximate random tumbling behavior).
