We are levaring power of Arm v8 64bit which is power-savvy and fits our current power budget. In future hardware will improve to accommodate more complex space computation cases. Detailed technical specs are - 8GB RAM Memory- Storage up to 1TB- GPU Speed up to 8 TOPS- Linux Debian- Cryptographic coprocessor for supporting state-of-the-art encryption and data source attestation
Our current orbit time is approximately 90 minutes, flying at speed of approx 7km per second
Daily data rate per node is 250KB with potential to increase up to 300MB in current setup.
With ever orbiting satellites, we can task satellites to verify location particular device on Earth with our Proof-of-Location entropy protocol.
Where in current situation space computation capacity is limited comparing usual data center resources, in the future it will be far more feasible operating space based data center on orbit due 24/7 solar energy.
Latency varies significantly, but is predictable according to orbital mechanics. Latency to send 1KB to one particular node in the network can be within a few seconds up to 30 min. In future it will be instant.
Current implementations are kept in private for various PoCs demos to showcase possibilities. In the future can run any kind of Dapp as you are familiar from UTXO-based, EVM-based or SVM-based chains.
Data centers in space can utilize high-intensity 24/7 solar power unhindered by day/night cycles, weather, and atmospheric losses (attenuation). This enables orders of magnitude lower marginal energy costs, resulting in drastic operating cost savings versus their terrestrial counterparts. Recent published study claims former.
Cost comparison of a single 40 MW cluster operated for 10 years in space vs on land follows: Terrestrial $167m and Space $8.2m. Source - Lumen Orbit Whitepaper
The global data center market size was estimated at USD 256.05 billion in 2024 and is projected to reach around USD 775.73 billion by 2034, growing at a CAGR of 11.72% - SourceAdvantages of space-based data centers are - Reduced cooling costs- Access to solar power- Potentially lower latency for certain applications- Significant reduction in CO2 emissions- No need for water coolingEstimating percentage of the market that could be addressable by space-based solutions given unique advantages and the fact that space-based data centers are still a nascent concept, we can conservatively estimate that they could potentially capture 5-10% of the overall data center market in the long term.Using the projected market size for 2034 (USD 775.73 billion) and assuming a 5-10% potential market share:TAM for space-based data centers (2034) = USD 775.73 billion * (5% to 10%)= USD 38.79 billion to USD 77.57 billion
