About CharterSpace.IO

The listing layer in between.

Launch capacity is sold in large, slow units. A rideshare slot is booked months ahead against a manifest deadline, and whatever is unsold when that deadline passes flies empty. The organisations most likely to want a hundred kilograms at short notice are the ones least equipped to run a procurement process against every provider to find it.

Why CharterSpace.IO exists

Residual capacity is real, perishable, and hard to find

Providers publish the residual mass and volume they are holding; shippers search it, see the constraints before they commit to a conversation, and request a quote from the party that can actually give one. Every listing shows the operator’s own figures for mass, volume, dimensional envelope and launch window — not an estimate we generated.

Whichever side you are on

Two sides of the same launch

CharterSpace.IO is a marketplace — the place the two sides meet, not a third one taking a side. An account gets you in; the capacity stays the provider’s to price and to sell, which is why both sides work from the same listing.

You are flying with mass to spare

Residual mass earns nothing once the manifest closes. A provider account puts your empty legs in front of the demand side — the shippers already searching that launch window — with your own figures and constraints on the listing, and every request that comes back yours to accept or decline. What you get here is the reach and the screening; what you sell is your own capacity, at your own price.

CharterSpace.IO for providers

Provider accounts are set up with us, not self-serve. Get in touch to start listing.

You need to ship, and the window is tight

Somebody is already flying it. Search what providers have listed — mass, volume, dimensional envelope and launch date stated up front — then send a structured quote request to the operator holding the slot. An account is what carries your organisation identity and declarations into that request; the request, and any booking that follows, are between you and the provider.

Browsing needs no account. You will need one to send a request — get in touch if you do not have one yet.

Where CharterSpace.IO stands

What we are, and what we are not

CharterSpace.IO is a marketplace.

It is not a broker, not a launch provider or operator, and not affiliated with any provider whose capacity appears on the platform.

What we do

  • Aggregate residual capacity from launch providers into one searchable listing, with the mass, volume, dimensional envelope and launch window stated up front.
  • Structure the quote request so a provider receives a complete, screened enquiry — organisation identity, cargo specification, export-control and cargo-safety declarations — instead of an email that needs three rounds of clarification.
  • Keep the record straight from request to booking, with one reference number that appears on the confirmation page, in your dashboard, and on every email about that request.

What we do not do

  • We do not operate launch vehicles and we do not manifest cargo.
  • We do not decide whether a payload flies — the launch operator does, and the provider is the one holding that relationship.
  • We are not a party to the contract of carriage, we do not handle or insure cargo, and we do not qualify or approve anyone’s hardware.

Being explicit about this is not a disclaimer we bury at the bottom of a page. It determines what our figures mean: capacity numbers on a listing are supplied by the operator or provider, not generated or verified by us, and no listing is a reservation until a provider has confirmed it.

Not guaranteed. Listed capacity can be de-manifested at any time at the operator’s sole discretion, and all capacity is subject to export control laws and regulations. Read the full Risk Disclosure and the Prohibited Cargo Policy before you request a quote.

How we handle compliance

Disclosure is the default path, not an afterthought

Space cargo sits inside export control, and the honest position is that this is the shipper’s obligation, not something a marketplace can absorb. What we can do is make disclosure the default path: every quote request captures export-control and physical-safety self-certifications by electronic signature before it reaches a provider.

Answering “yes” to a controlled-cargo question does not stop a request. It routes it, with the licence details attached, to the people qualified to review it. What ends a request is a declaration that turns out to be false.

Where this is going

A short, true feature list

Live today

  • Listing and search of residual capacity
  • Structured quote requests
  • Bookings with one reference number end to end
  • A provider API for operators who publish capacity from their own systems

On the roadmap, not live

  • Interactive route mapping

  • Calendar sync for providers
  • On-chain booking certificates

We would rather ship a short, true feature list than a long, aspirational one.
