名前種類概要
loadSpacecraft関数Load the fitted paths of some spacecraft (or all of them), each a table of its own that nothing else imports: about 6 kB gzipped for the Voyagers, the Pioneers, New Horizons and JWST, and more for the craft that orbited a planet.
SPACECRAFT定数The ten craft and their facts, keyed by id.
SPACECRAFT_IDS定数The ten craft: voyager1, voyager2, newhorizons, pioneer10, pioneer11, cassini, galileo, juno, parker and webb.
spacecraftEarthDistance関数A craft's distance from the Earth's centre at a moment, in kilometres: the craft's path from Horizons and the Earth from VSOP87B (a few thousand kilometres at most), both for the same instant, with no allowance for the light's travel.
spacecraftErrorKm関数The worst error of a craft's loaded path against Horizons, in kilometres, as measured when it was made: on samples held back from the fit and on fresh samples at random times.
SpacecraftEvent型One thing that happened on a craft's voyage.
SpacecraftFacts型Facts about one craft.
SpacecraftId型The name of a craft: voyager1, cassini, webb...
spacecraftLightTime関数How long a radio signal takes from the Earth to a craft (or back), at a moment, in seconds: the distance from the Earth over the speed of light.
spacecraftPosition関数Where a craft is at a moment: x, y, z in kilometres from the Sun, in the J2000 ecliptic frame (the same axes as heliocentric, which is in astronomical units).
spacecraftSpeed関数A craft's speed relative to the Sun at a moment, in kilometres a second.
spacecraftSunDistance関数A craft's distance from the Sun at a moment, in kilometres.
spacecraftVelocity関数A craft's velocity relative to the Sun at a moment, in kilometres a second, in the same frame as spacecraftPosition.
When型A moment: a Date or a number of milliseconds since 1970 (UTC, as JavaScript counts).
