In plain terms

As of 2013 the experiment needed to check these predictions had still not been done.

The claim as recorded

The same 2013 review states that the predictions of non-critical ionospheric effects need to be fully verified in the early phase of space experiments, so as of 2013 the verifying experiment remained outstanding.

Scope and limits

Establishes the position as of June 2013 only. It does not establish that nothing has been done since. One later source has been checked: a 2026 commentary (SRC-588) says later studies "have not led to any consensus about how the SBSP power beam will interact with the ionosphere" (PDF p.2), calls for "wider experimental study of SBSP interactions with the ionosphere" (PDF p.4), and says the Japanese OHISAMA mission, "due for launch in 2026", will "undertake some assessment of ionospheric constraints on SBSP" (PDF p.4). It does not say whether the 2013 predictions have been verified in space.

What it assumes

No assumptions are recorded against this claim.
