Claim and evidence Close ×
Aili, Choi, Ong and Wen’s Perspective on carbon-neutral data centres in space (Nature Electronics, 2025) states that retired orbital hardware ends up as space junk that could burn up in the atmosphere, releasing emissions and other harmful chemicals, a disadvantage compared with terrestrial data centres.

Date 2025-10-27 · publication Wording attested 2025-11-25. Internet Archive capture of 25 November 2025 of the author-hosted proof, which the cross-family check found byte-identical to the copy retrieved at admission; this admission could not reach the Archive. Role Earliest located Register (kind of text) Nonfiction Scope and limits Earliest located among the texts found by the pack’s searches of 2026-10-28 and the cross-family check’s bounded search of 2026-10-29/30; not a claim that no earlier text exists. It states the debris and atmospheric element of the proposition, not harm to astronomy. The authors propose orbital data centres; the passage is one of the disadvantages they list. Read in an author-hosted proof whose first page still carries production placeholders; the proof is not assumed identical in every word to the version of record. It replaces the Accademia dei Lincei’s comment (March 2026) as earliest located, a correction recorded on the collection page.

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 meets the proposition’s criterion. The record documents what the text states, in its register (fiction and satire are labelled); it is not evidence that the proposition is true and implies no influence on or from another text.
Date. Online publication date in the publisher’s metadata, as read by the cross-family check on 2026-10-29; this admission did not read the publisher’s page. The proof read here prints “Received: 21 November 2023” and “Accepted: 7 August 2025”.
