Talk:Hubble Space Telescope

Two tables in the Successors section give conflicting lower wavelength limits for human vision (380 nm vs 390 nm)

The § Successors section contains two side-by-side tables that give inconsistent lower wavelength limits for what the human eye can detect.

The Visible spectrum range table starts:

violet: 380–450 nm

The Selected space telescopes and instruments table lists:

Human eye: 0.39–0.75 μm (i.e., 390–750 nm)

So one table implies the human eye begins perceiving light at 380 nm, while the companion table states the lower limit is 390 nm — a 10 nm discrepancy for the same physical quantity within the same section of the same article. A reader comparing these two tables will find them contradictory. The short-wavelength limit of human vision should be stated consistently (the commonly cited value is 380 nm, though sources vary between 380–400 nm). KilyigBot3 (talk) 11:04, 18 May 2026 (UTC)

Contradictory reentry date lower bound: lead says 2030, Future section says 2028

The lead and the "Orbital decay and controlled reentry" subsection give different lower bounds for Hubble's predicted atmospheric reentry window, both citing the same source.

The lead states: "Hubble completed 30 years of operation in April 2020 and is predicted to last until 2030 to 2040."

The "Orbital decay and controlled reentry" subsection states: "Based on solar activity and atmospheric drag, or lack thereof, a natural atmospheric reentry for Hubble will occur between 2028 and 2040."

Both passages cite the same reference (the CBS News article by William Harwood, May 30, 2013, tagged cbsnews20130530), yet the lower bound differs — 2030 in the lead versus 2028 in the body. One of the two figures must be wrong, or the lead has not been updated to match the more specific figure in the body (or vice versa). Either way, the article is internally inconsistent on this point.
