What's your moonshot?

Beating Elon Musk in his game, for starts.

We are working on making space more accessible for everyone, through "satellite-as-a-service" model. We will allow software developers to upload their code to our satellite, creating an application development platform in space.

You can read more about us at our website in parent comment.

What is your approach to time sharing, and packaging? Do I send you an ELF binary, source, a Docker container?

I read: https://www.exodusorbitals.com/files/nova_mission.pdf

Will there only be one instance of the "user segment" per Satellite, or will there be one supervisor / bus, with lots of simultaneously running user segments?

The short answer: you send us the source, we build, test and deploy the application package (binary+configuration files) to the satellite user segment.

The answer to "one or many user segments" will depend on what we will learn from that ESA mission ourselves. Some satellite instruments can be shared simultaneously, some require exclusive access and have to be accessed in sequential order.

I'm not sure what you mean, but you're not building and launching rockets afaict.

The endgame for SpaceX (and us) is not building and launching rockets (or satellites).

The endgame for all of us is large-scale colonization of Solar System.

Excellent, self promote! Diving into the site now
