Altered Postnatal Chromatin Development In The Nucleus Accumbens Primes Enduring Stress Sensitivity, Rebekah L Rashford, Lisa Z Fang, Michael Deberardine, Hye Ji J Kim, Laura W Hirschfield, Ella Cervi, Mason R Barrett, Jeremy M Thompson, Meaghan C Creed, Catherine Jensen Peña

2020-Current year OA Pubs

Early life stress (ELS) sensitizes individuals to subsequent stressors to increase lifetime risk for psychiatric disorders. Within the nucleus accumbens (NAc)-a key limbic and reward-associated brain region-ELS sensitizes both cellular and transcriptional response to later stress, which are programmed by enduring epigenetic changes. Among the histone modifications persistently enriched by ELS in NAc is H3K4me1, which is associated with open chromatin and epigenetic priming of genomic enhancers. Here, we sought to determine whether H3K4me1 enrichment in NAc was sufficient to prime cellular and behavioral responses to adult stress. Viral-mediated overexpression of the histone H3 monomethyltransferase

Lightweight Open Source On-Spacecraft Machine Learning With Mlpack And F Prime, Ryan R. Curtin, Scott M. Gilliland, Sterling L. Peet

Small Satellite Conference

Onboard machine learning is an increasingly important topic in spaceflight systems, as machine learning and AI models are increasingly used for data processing, anomaly detection, attitude control systems, and other predictive applications. However, successfully deploying a machine learning model in a spaceflight computing environment is fraught with difficulty, as spaceflight computing environments are low-resource, but typical machine learning software solutions are implemented in languages like Python, which require an interpreter and other heavyweight dependencies. It is therefore virtually mandatory for any on-spacecraft machine learning to be written with lightweight toolkits that minimize dependencies and resource usage.

We demonstrate a solution …

A Novel Deployable Telescope For Small Satellites Using Adaptive Optic Technology, William Hill, Harbinder Rana, Darren Jones, Trevor Wood, Zac Thomas, Thomas Lacy, Duncan Housden, Calum Meredith

Small Satellite Conference

SSTL has been developing a deployable telescope with funding from the UK Defence and Security Accelerator (DASA). The aim of the study was to design a telescope that could achieve higher resolutions in the visible spectrum while utilising a smaller launch volume. To achieve a cost-effective launch the deployable system has been sized such that it would fit within a representative SSTL platform in a SpaceX Falcon 9 small satellite launch volume. A monolithic system with equivalent performance would require a larger launch volume and, therefore, it is expected that a deployable telescope can secure an overall mission price advantage. …

Scaling Up Monolithic Optics Capabilities: 25cm Aperture And Beyond, Cohl Houldin Hatala, Jordan Smilo, Wim De Vries, Brian Bauman, Christian Tolfa, John Cortes, Paul Rosso, Aaron Godfrey, Darrell Carter, Michael Wong, Seth Cornman, Josephine Smith, John Ganino, Ben Bahney

Small Satellite Conference

The 25 cm “V10” Monolithic Optical Payload has been developed through study phase design into a fully qualified system ready for on-orbit demonstration. This extends Lawrence Livermore National Laboratory’s monolithic telescope technology toward a rapidly fieldable, high performance space imaging system for small and medium spacecraft buses. Centered on the V10 monolithic Cassegrain optic in fused silica, the payload provides highly robust, diffraction limited performance with inherently maintained mirror alignment, eliminating complex on orbit alignment procedures and significantly reducing mechanical risk. The V10 optic is paired with a heritage focus mechanism and a panchromatic commercial off the shelf CMOS detectors, …

Payload Operation Using On-Board Vision Language Model, Meirav Nevo, Oshri Fatkiev, Guy Zaidman, Doron Shterman

Small Satellite Conference

The rapid maturation of multimodal vision-language models (VLMs) has significantly expanded artificial intelligence applications at the edge, including spaceborne systems. In this work, we present one of the first demonstrations of deploying a compact vision-language model directly on a very-high-resolution Earth-observation satellite payload processor, enabling autonomous on-orbit scene understanding and near real-time decision-making. This represents a paradigm shift in satellite operations, moving from ground-centric processing toward intelligent, self-directed spacecraft. 

Conventional Earth-observation missions rely on ground-based image processing and interpretation, introducing latency, downlink bandwidth constraints, and limited operational responsiveness. By embedding a VLM on board the satellite, visual reasoning can be …

A Miniaturized, High Geometric Factor, Electrostatic Analyzer For Fast Plasma Measurements, Dhiren Kataria, Justyna M. Sokol, Jianliang Lin, Camden Ertley, Jonathan Gasser, Guy Grubbs, Kwang-Joo Hwang, Michael Starkey

Small Satellite Conference

With advances in machining techniques that can manufacture high aspect ratio structures at high accuracy, cylindrical geometry electrostatic analyzers present a versatile alternative to spherical designs. We report on the development of the 3D Cylindircal And Tiny Spectrometer (3D-CATS), a novel space plasma analyzer that performs instantaneous 3D (multiple energy, azimuth and elevation angles) measurements, providing differential energy, wide field of view particle imaging in a compact, low-SWaP (size, weight and power) package.

The baseline analyzer design consists of a nest of 8 cylindrical analyzers, providing measurements of incoming particle energy distributions over an energy range of 10 eV to …

Uncertainty Quantification And Platform Scattering For The Cimr Reflector Antenna, Tonny Rubaek, Pasquale Giuseppe Nicolaci, Cecilia Cappellin

Small Satellite Conference

The Copernicus Microwave Imaging Radiometer (CIMR) employs a 7.1 m conical scanning mesh reflector antenna rotating at 7.8 rpm that operates from L to Ka band. Demanding radiometric accuracies and sensitivities at few tenths of a Kelvin at high spatial resolution are targeted for the instrument. These require a high accuracy in the characterization and modelling of the antenna pattern over 4π, considering any nearby scattering structure, and/or any potential multipath due to the antenna installation on the S/C, as well as the quantification of the uncertainty on the beam efficiency (BE) arising (from possible in-orbit random variations in the …
