The Certificate of Return
The record is the proof.
Anything can be said to have been to space. A Nostimere object can prove it. Each one comes home with a Certificate of Return, the document a partner keeps beside the object for as long as the object exists.

For the House
What it records
Exact facts, nothing rounded.
A certificate makes no claim the House could not defend. Every line is observed, logged and kept.
- The object
- What was flown, its edition and its number, as the partner house names it.
- The mission
- The Space Phoenix mission that carried it, and the days it spent in orbit.
- The dates
- Departure and return, written out in full, to the second, in UTC.
- The mass
- Weighed before departure and after return, to the hundredth of a kilogram.
- The recovery
- Where the object came back to earth and was taken into the House’s care.
- The number
- A unique number that ties the certificate to the House archive.
How it is made
Made to outlast the object it describes.

The sheet
600 gsm cotton, in Historic Marble
11 × 8.5 inches, heavy enough to stand on its own.
The printing
Letterpress in Nostimere Blue
Pressed into the sheet, so the record can be felt as well as read.
The seal
Struck in gold foil
The one round mark the House uses, kept for what has returned.
The archive
Kept for a century, open to verification.
The House keeps a copy of every certificate and the record behind it. A collector, an auction house or an auditor can ask the House to confirm a certificate by its number, decades from now.
The object is the partner’s. The return, and the record of it, is the House’s.

Every certificate begins with a conversation.
The House works with a small number of partners on each mission, by appointment.
