Astrosoft: Scalable Cloud Solutions for Space ScienceSpace science has entered a new era. Observatories, satellite constellations, and planetary missions generate petabytes of data every year. Processing, storing, and analyzing that data demands specialized infrastructure—flexible, distributed, and cost-efficient. Astrosoft positions itself as a scalable cloud platform tailored to the needs of space science, combining high-performance compute, data management, and domain-specific tools. This article explores Astrosoft’s architecture, core capabilities, use cases, operational model, and how it addresses the unique challenges of modern space science.
Why space science needs scalable cloud solutions
Modern space projects produce heterogeneous datasets: multi-spectral imagery, time-series telemetry, radio astronomy voltages, and simulation outputs. The volume and velocity of incoming data exceed what many traditional on-premise systems can handle affordably. Key pressures include:
- Burst compute demands during mission events (e.g., flybys, calibration campaigns).
- Collaboration across institutions and countries with differing IT capabilities.
- Long-term archival needs balanced with rapid access for analysis.
- Specialized processing pipelines requiring GPUs, FPGAs, or large-memory nodes.
A cloud-native, scalable approach allows teams to provision resources on demand, parallelize workloads across thousands of cores, and integrate modern data pipelines without heavy upfront capital expenditure.
Core architecture of Astrosoft
Astrosoft adopts a modular, cloud-native architecture with components designed specifically for space-science workflows:
- Ingest & Message Bus: Highly available, scalable ingestion layer that accepts streaming telemetry, bulk uploads, and push notifications from ground stations. A message bus (Kafka-compatible) allows decoupled processing and real-time routing.
- Object Storage & Tiering: S3-compatible object storage with automatic lifecycle tiering (hot/cool/cold) to balance cost and access latency. Metadata indexing supports fine-grained discovery of observations and files.
- Compute Fabric: Kubernetes-based orchestration with heterogeneous node pools—CPU, GPU, and FPGA-backed instances. Auto-scaling policies target queue depth, deadline SLAs, or cost thresholds.
- Workflow Engine: Declarative workflow engine for pipeline orchestration (DAGs), supporting containerized tasks, GPU scheduling, and checkpointing for long-running simulations.
- Data Catalog & Provenance: Centralized catalog tracks datasets, processing lineage, and experiment metadata. Provenance ensures reproducibility and simplifies regulatory or publication requirements.
- Interactive Notebooks & APIs: Hosted Jupyter/VS Code environments with preinstalled astronomy libraries (Astropy, CASA, healpy, TensorFlow/PyTorch) and direct access to storage/APIs.
- Identity, Sharing, and Access Controls: Fine-grained RBAC, federated identity (supporting institutional SSO), and secure project-level sharing for multi-institution collaborations.
- Cost & Quota Management: Tools to estimate, monitor, and cap spend per project or user, with policy-driven automation to reduce idle resources.

Typical use cases
Satellite imaging analytics
- Large constellations produce continual imagery. Astrosoft enables near-real-time ingest, automated calibration, mosaic generation, and anomaly detection via ML models that scale horizontally.
Radio astronomy and interferometry
- Correlating voltages from dozens to thousands of antennas requires dense compute and low-latency data movement. Astrosoft’s GPU/FPGA node pools and optimized I/O reduce correlation time and support on-the-fly imaging.
Planetary mission science pipelines
- Missions often have bursty downlinks after high-priority events. Astrosoft provides rapid reprocessing, versioned archives, and collaborative notebook environments for instrument teams.
Simulations and model ensembles
- Climate/atmospheric models for planetary studies or synthetic observation generation can run as large ensembles with checkpointing, then be compared against observational datasets stored in the system.
AI model development and deployment
- Training large ML models on labeled astronomy datasets and deploying them as scalable inference services for real-time detection of transients or classification of sources.
Cost model and operational considerations
Astrosoft typically offers a mix of pricing options to accommodate research budgets and enterprise missions:
- Pay-as-you-go for transient workloads and smaller projects.
- Committed-use discounts for predictable pipelines or long-term missions.
- Data egress and storage tiering to reduce recurring costs.
- Project-level quotas and alerts to prevent runaway spend.
Operationally, mission teams should plan for:
- Data ingest patterns and expected peak rates to size pipeline concurrency.
- Lifecycle policies for archival to balance immediate access vs storage cost.
- Governance around shared datasets and compute to prevent noisy-neighbor effects.
Integrations and extensibility
Astrosoft supports integration with common tools and standards:
- Authentication via SAML/OAuth to connect institutional identities.
- Standard astronomy formats (FITS, HDF5, netCDF) and interoperability with VO (Virtual Observatory) protocols.
- Plugin system for custom instrument-specific processors and third-party analytics tools.
- Export connectors to downstream archives, publication platforms, or national data centers.
Challenges and limitations
- Egress and cross-region replication can be costly for very large datasets unless mitigations (on-cloud analysis, caching) are used.
- Extremely low-latency correlator workflows may still require specialized on-prem hardware near the antenna for best performance.
- Data governance across international collaborations requires careful policy mapping (export controls, privacy for commercial imagery).
Example workflow: Near-real-time transient detection
- Ingest: Satellite/telescope pushes image tiles to Astrosoft’s object storage; ingestion events are published to the message bus.
- Preprocess: A fleet of containerized workers performs radiometric corrections and astrometric alignment.
- Difference imaging: Parallelized jobs generate difference images against a reference catalog.
- ML inference: A GPU-backed inference cluster scores candidates and performs classification.
- Alerting & provenance: High-confidence detections trigger alerts to subscribed teams; full provenance is recorded for each detection to support verification and publication.
Future directions
Astrosoft’s roadmap could include:
- Deeper edge integration with ground stations for pre-processing and compression before cloud transfer.
- Native support for federated learning to train models across institutional datasets without moving raw data.
- Automated experiment optimization using cost-aware scheduling and AI-driven pipeline tuning.
- Expanded support for real-time radio astronomy pipelines using serverless FPGA acceleration.
