Lessons Learned During The Implementation Of A Cold Gas Propulsion System For The Sunrise Mission, Ryan Martineau, Tyson Smith, Matt Felt, Cameron Weston, Blake Rusch, Robert Fowler, Emma Brown, Adam Farmer, Tim Neilsen, Craig Thompson, Alex Kirkman, Paul Fluckiger, Shawn Morrison, Dave Wittner, Frank Picha, Jeffrey Weiss, Nathan Daniel, Samuel Wood, Mackenzie Glaser

Small Satellite Conference

The SunRISE mission utilizes a two-phase cold gas propulsion system, which provides several advantages over other cold gas systems but experienced challenges during assembly and testing. Since 2020, Georgia Tech Research Corporation (GTRC), Utah State University Space Dynamics Laboratory (SDL), and the Jet Propulsion Laboratory (FPL) have implemented several improvements to the SunRISE propulsion system.

The SunRISE propulsion system leverages an additively manufactured monolithic structure, commercial off-the-shelf (COTS) valves and transducers, and the benign working fluid R-236fa to provide a suitable propulsion system for the SunRise mission. While the GTRC propulsion system had been developed for other missions, the multi-organizational …

The Journey Of The Lunar Flashlight Propulsion System From Launch Through End Of Mission, Celeste Smith, Nathan Cheek, Christopher Burnside, John Baker, Philippe Adell, Frank Picha, Matthew Kowalkowski, Glenn Lightsey

Small Satellite Conference

The Lunar Flashlight Propulsion System (LFPS) was developed as a technology demonstration to enable the Lunar Flashlight spacecraft to reach Lunar orbit and to desaturate onboard reaction wheels. While the system produced over 16 m/s of delta-v and successfully managed momentum, variable thrust performance, most likely due to debris in the propellant flow path, kept the spacecraft from reaching the Moon. This paper details the in-flight journey of the LFPS, highlighting both successes and challenges met throughout the mission, and provides lessons learned applicable to future CubeSat missions and additively manufactured propulsion systems.

Small Satellite Conference

We present an update on the life qualification of the Magnetically Shielded Miniature (MaSMi) Hall thruster (also known as the ASTRAEUS Thruster Element), which was developed at the Jet Propulsion Laboratory and was recently licensed to ExoTerra Resource for flight production (renamed Halo12). In 2020-2021, the thruster successfully completed a 7205-hour wear test at operating powers from 200-1350 W, processing over 100 kg of xenon propellant and producing 1.55 MN-s total impulse with no measurable degradation in performance. The wear test is being extended to further demonstrate the service life capability of the thruster. In separate tests, prot-flight MaSMi hollow …

A Ray-Tracing Algorithm For Computing Self-Shadowing Of Complex Spacecraft Geometries, Matt Pierce, Jack Huun

Small Satellite Conference

As spacecraft geometries become more complex, particularly for In-Space Servicing, Assembly, and Manufacturing (ISAM) missions, higher fidelity models of shadowing are often necessary for more accurate planning and performance modeling in the mission operations center. For geometries where a vehicle may shadow a large portion of itself, these models must consider self-shadowing events, in addition to planetary eclipses, to provide an accurate estimate of forces and torques from Solar Radiation Pressure (SRP) and more realistic power generation estimates. SRP plays a pivotal role in determining spacecraft fuel usage and momentum accumulation. Many existing models simplify spacecraft geometries to either a …

Design Of A Low Micro Vibration High Precision Cubesat Reaction Wheel, Cedric Cuypers, Tjorven Delabie, Jelle Lanting, Win De Munter, Rhimas Van De Putte, Joren Malfroy, Lubna Hamid

Small Satellite Conference

Rolling element bearings are known to generate higher order harmonics. These harmonics can reach up to the 10th or higher engine order [1]. When wheels are used in a wide speed range, these higher order harmonics can pass and excite rotor eigenfrequencies and rotor modes, severely increasing the exported μ-vibrations at these frequencies. The amplification of these frequencies will then be governed by the quality factor (Q-factor) of the rotor. Single piece rotors have several advantages such as affordable tight tolerances, uniform mass and elimination of assembly errors, but such monolithic metallic structure feature high Q-factors. Material choice is …

Small Satellite Conference

EQUULEUS (EQUilibriUm Lunar-Earth point 6U Spacecraft) is a spacecraft to explore the cis-lunar region including the Earth-Moon Lagrange point L2 (EML2). The spacecraft is being jointly developed by JAXA, the University of Tokyo, and several other universities in Japan. After being launched into a lunar transfer orbit by NASA's SLS (Space Launch System) Artemis-1 on November 16, 2022, the spacecraft successfully performed a first Delta-V and a trajectory correction maneuver. This enabled a precise lunar flyby and successful insertion into the orbit toward EML2.

Although the size of EQUULEUS is only 6U CubeSat, the spacecraft carries three different science instruments. …
