name{ en: string; ja: string; }

The craft's name in English and Japanese.

agencystring

The agency or agencies.

launch{ date: number; precision: "minute" | "day"; site: { en: string; ja: string; }; vehicle: string; }

The launch: when, from where and on what.

endnumber | undefined

The end of the mission (the last signal, or the planned plunge), in milliseconds since 1970 (UTC), or undefined while it goes on.

status"ended" | "active"

"active" while NASA's page lists the mission as active, else "ended".

urlstring

NASA's page for the mission.

horizonsstring

The craft's number in JPL Horizons.

record{ start: number; end: number; }

The span of Horizons' record of the craft, in milliseconds since 1970 (UTC), which is the span spacecraftPosition answers for. The record begins about an hour after the launch; for a craft still flying, its end is Horizons' predicted path.

joinsreadonly { date: number; km: number; }[]

Places where Horizons' record steps by more than the fit's error because two solutions meet there: at date (milliseconds since 1970, UTC) the position jumps by km kilometres, and a line drawn through the path should break. Empty where the record is smooth.

eventsreadonly SpacecraftEvent[]

The voyage, in order.

const cassini: SpacecraftFacts = SPACECRAFT.cassini;
console.log(cassini.name.ja, cassini.agency, cassini.status);
