- AI in Space Exploration: A Server Configuration Overview
This article details the server infrastructure required to support Artificial Intelligence (AI) applications in the field of space exploration. It is aimed at newcomers to our MediaWiki site and provides a technical overview of the hardware and software considerations. We will cover data acquisition, processing, and model deployment aspects. This is a rapidly evolving field, so consider this a snapshot of current best practices.
Introduction
The integration of AI into space exploration is revolutionizing our ability to analyze vast amounts of data, automate spacecraft operations, and make critical decisions in real-time. This requires robust and scalable server infrastructure, both on Earth for initial model training and data analysis, and potentially on spacecraft for autonomous operation. This article focuses primarily on the Earth-based infrastructure, as in-space computing presents unique challenges (see In-Space Computing Challenges). Understanding the server configuration is crucial for successful AI deployment in missions like Mars Sample Return and Europa Clipper.
Data Acquisition and Pre-processing Servers
Space exploration generates massive datasets from various sources – telescopes, satellites, rovers, and probes. The initial stage involves receiving, storing, and pre-processing this data. This requires a dedicated server cluster.
| Server Component | Specification | Quantity |
|---|---|---|
| CPU | Intel Xeon Gold 6338 (32 Cores) | 8 |
| RAM | 512GB DDR4 ECC REG | 8 |
| Storage | 2 x 10TB NVMe SSD (RAID 1) + 8 x 16TB HDD (RAID 6) | 8 |
| Network Interface | 100Gbps Ethernet | 8 |
| Operating System | CentOS 8 | 8 |
These servers utilize high-bandwidth network connections to ingest data from Deep Space Network and other data sources. Pre-processing steps include data cleaning, calibration, and format conversion. Software used includes Python with libraries like NumPy, SciPy, and Pandas, as well as specialized astronomical data reduction packages like Astropy. The processed data is then moved to the AI training servers. Data storage utilizes a distributed file system like Hadoop Distributed File System. The pre-processing pipeline is monitored using Prometheus.
AI Training Servers
Training AI models, particularly deep learning models, demands significant computational power. This is typically achieved using GPU-accelerated servers.
| Server Component | Specification | Quantity |
|---|---|---|
| CPU | AMD EPYC 7763 (64 Cores) | 4 |
| RAM | 1TB DDR4 ECC REG | 4 |
| GPU | NVIDIA A100 80GB | 8 (2 per server) |
| Storage | 2 x 2TB NVMe SSD (RAID 1) | 4 |
| Network Interface | 200Gbps InfiniBand | 4 |
| Operating System | Ubuntu 20.04 | 4 |
These servers run machine learning frameworks like TensorFlow, PyTorch, and Keras. Distributed training strategies are employed using libraries like Horovod to accelerate the training process. Model versioning and management are handled by MLflow. The servers are integrated into a cluster managed by Kubernetes. GPU utilization is monitored using NVIDIA SMI. Training data is typically accessed from the pre-processed data store.
Model Deployment and Inference Servers
Once trained, AI models need to be deployed for real-time inference. This requires servers optimized for low-latency predictions.
| Server Component | Specification | Quantity |
|---|---|---|
| CPU | Intel Xeon Silver 4310 (12 Cores) | 6 |
| RAM | 256GB DDR4 ECC REG | 6 |
| GPU | NVIDIA T4 16GB | 6 |
| Storage | 1TB NVMe SSD | 6 |
| Network Interface | 10Gbps Ethernet | 6 |
| Operating System | Debian 11 | 6 |
These servers utilize model serving frameworks like TensorFlow Serving and TorchServe. Inference requests are received via REST APIs. Load balancing is handled by HAProxy. Monitoring and alerting are implemented using Grafana and Alertmanager. The inference servers are often deployed in a containerized environment using Docker. Considerations for edge deployment, closer to data sources, are documented in Edge Computing for Space. We also use gRPC for efficient communication. Security is paramount, and servers are behind a robust firewall managed by the Security Team.

Future Considerations
Future server configurations will likely incorporate more specialized hardware, such as TPUs (Tensor Processing Units), and explore the use of federated learning to train models on distributed datasets without centralizing the data. Quantum computing may also play a role in solving complex optimization problems in space exploration.
