Record
A brief history of spaceloading
The word is new; the act is not. Humanity has been sending data through space for as long as it has been sending anything at all — the record below is the act, growing into an industry.
-
1957
Sputnik 1
The first artificial satellite. Its radio beeps, tracked by amateurs worldwide, are the first data ever transmitted from orbit — spaceloading's opening signal.
-
1962
Telstar 1
Relays the first live transatlantic television broadcast. For the first time, the public's media travels through space on its way to them.
-
1977
The Voyager Golden Record
A gold-plated copper record carrying Earth's sounds and images leaves for interstellar space aboard the Voyager probes — the first deliberate deep-space archive, and the most permanent spaceload ever made.
-
1990s–2000s
Space becomes routine infrastructure
Satellite television, GPS, and early satellite internet make data-through-space an everyday utility. The links are there; the destinations are still all on the ground.

2019
The Lunar Library
The Arch Mission Foundation's thirty-million-page archive, etched on nickel discs, rides Israel's Beresheet lander. The lander crashes; analyses suggest the archive likely survived on the surface — an accidental proof of how durable an off-planet backup can be.

2021–2024
Laser mesh in orbit
Starlink builds out optical crosslinks by the thousands, passing traffic satellite-to-satellite. A data backbone now exists above the atmosphere. NASA's TBIRD experiment demonstrates a 200 Gbps optical downlink — proof the pipe down can widen.

2024–2025
Direct-to-cell goes live
Unmodified phones begin exchanging messages through satellites in commercial beta service. Spaceloading reaches the device in everyone's pocket, unannounced.
-
March 2025
A data center reaches the Moon
Lonestar's miniature data-center payload flies aboard Intuitive Machines' Athena lander and tests data storage and transmission around and on the Moon. The lander tips over on touchdown; the milestone stands.
-
November 2025
A data-center GPU in orbit
Starcloud-1 carries an NVIDIA H100 to low Earth orbit — data-center-class silicon flying for the first time — and runs models in space. Orbital compute moves from concept to hardware.
-
November 2025
Project Suncatcher
Google announces a research program toward scaled machine-learning compute on solar-powered satellite constellations, with prototype launches targeted for 2027. The largest infrastructure builders are now designing for orbit.
-
2024–2026
The gigawatt conversation
Europe's ASCEND feasibility study makes the public case for orbital data centers; gigawatt-scale concepts enter serious discussion among the industry's largest figures. The question shifts from whether to when, and at what cost per watt.
Open constraints
Heat rejection in vacuum, radiation-tolerant hardware, launch cost per kilogram, and downlink bandwidth remain the four governing constraints. Progress on each is tracked in the field notes.
