Cavalier's IEEE Spectrum article (June 2026) calls "free cooling" perhaps the biggest misconception about computing in space, because without an atmosphere only radiation can remove heat.

One recorded claim. The claim panel gives its qualification, the source passages with their place in each source, and how it was checked.

“Space is cold, but it also has no atmosphere. That means the best heat-removal mechanisms, conduction and convection, are off the table. The only option is radiation.”

Status and meaning

Editorial status. Not reviewed by an editor. An exploratory record that no editor has accepted. This status does not say whether a person has read any linked passage. Each evidence record above shows how it was checked.

Relation. A passage of the document disputes the proposition or a premise it depends on. The record documents the text’s position, not who is right.

Date. Date of publication, as the source gives it.
