Seal a letter today. We store it, fly the year's best of it past actual space, and deliver it back to you on the exact date you choose — five years from now, or ten.
Write Your LetterA pledge. A confession. The thing you keep almost-saying. Write your letter and attach it to a specific future date — nobody reads it before then, including us.
We print your letter, seal it, and lock the unlock date into the record. You'll receive a certificate of sealing immediately — proof the letter has already begun its wait.
Once a year, on Capsule Day, every Space Edition letter from the past twelve months is bundled together and flown on an actual spaceflight — past the Kármán line, 100km up, and home again.
Years from now, on the exact morning you picked, your letter lands back in your inbox — sealed words, opened by someone slightly different. Space Edition letters arrive stamped "Flown to Space."
One payment, no subscription. You're paying for safekeeping, not for the writing.
For the promise you need to keep by next year, not someday.
Enough distance to actually become someone different.
The classic distance. Long enough to forget you wrote it.
For the version of you that feels almost unreal right now.
Your letter is printed, included in this year's Capsule Day flight, and returned stamped "Flown to Space." Limited to the first 500 letters each year.
Only if you add Space Edition. Once a year on Capsule Day, we bundle that year's Space Edition letters and fly them on a real spaceflight past the 100km Kármán line. Every other letter is safely stored and returned on schedule — just without the flight.
Your letter is still sealed and on schedule regardless. If you've chosen Space Edition, it simply joins the following year's flight instead.
No — that's the entire point. Once it's sealed, it's sealed. Write it knowing it can't be unwritten.
Only you, on the date you chose. We can't open it early — and neither can you.
As many as you want, each with its own unlock date.
It arrives by email automatically, the morning of your chosen date. No login required, nothing to remember.
