Constellation meters compute against a PI and a funding line, so you can answer "what did this cost?" for any reviewer. Access is granted by request, there is no credit-card checkout, because there is no such thing as a casual petabyte.
Whether you arrive as a single academic PI or a multi-institution partner, you get the full Constellation runtime. What changes is the quota model and how we work together.
For individual PIs and university groups with a named grant. Subsidized rates, per-PI quotas, and a path to co-authorship on the methods paper. Cite Constellation in your results.
For observatories, consortia, and facilities running many groups. Per-grant quotas with cross-tenant fairness, dedicated onboarding, and signed cost-and-lineage exports for funding bodies.
For work co-funded under NASA SBIR or an observatory-partner program. Compute is drawn against the sponsored line; deliverables ship with full provenance for the program office.
There are no per-seat licenses. A quota is bound to a PI and a funding line, metered in real time, and rolled up wherever you need to account for it.
Each principal investigator gets a quota envelope in node-hours, fp64-hours, and storage.
Quotas roll up to a funding line so a department or facility can balance many PIs fairly.
Every run debits in real time; kernels report exact device occupancy, storage bills the dedup footprint.
Export a signed cost-and-lineage report by experiment, by paper, or by grant, whenever a reviewer asks.
Tell us the problem, the PI, and the funding line. We will scope a quota that fits the grant and get you a workspace. If we are not the right tool, we will tell you that too.
