	Grouping Ranger 8 with Surveyor 5 as "landers" is misleading: Surveyor 5 was a genuine [[Surveyor program\|soft lander]], while Ranger 8 was a [[Ranger program\|hard impactor]] deliberately designed to crash into the Moon while transmitting close-up photographs. The second sentence implicitly acknowledges this by using "crash site" for Ranger 8 and "landing site" for Surveyor 5. The first sentence should say something like "the automated Ranger 8 impactor, the Surveyor 5 lander, and the Lunar Orbiter mapping spacecraft" to avoid grouping them under a single misleading label.

			== First moonwalk described as both "six hours and thirty-nine minutes" and "six and a half hours" after landing — figures differ by nine minutes ==

			The Lunar surface operations section gives two different elapsed-time figures for approximately the same period following Eagle's landing, and they cannot both be correct.

			Claim 1: "Six hours and thirty-nine minutes after landing, Armstrong and Aldrin were ready to go outside, and Eagle was depressurized."

			Claim 2: "at 02:56:15, '''six and a half hours''' after landing, Armstrong stepped off Eagle's landing pad"

			The article states that Eagle landed at 20:17:40 UTC. The stated time of Armstrong's first step is 02:56:15 UTC (July 21). The actual elapsed time between those two events is:

			: 02:56:15 − 20:17:40 (+ 24 h) = '''6 h 38 min 35 s'''

			Six hours and thirty-nine minutes (6 h 39 min) is consistent with this calculation to within the nearest minute. ✓

			"Six and a half hours" equals exactly 6 h 30 min, which is '''nine minutes short''' of the actual elapsed time. ✗

			The two phrases thus disagree with each other by nine minutes, and "six and a half hours" also disagrees with the arithmetic implied by the article's own landing and first-step timestamps. The phrase "six and a half hours" in Claim 2 should be corrected to "six hours and thirty-nine minutes" (or "nearly six hours and forty minutes") to be consistent with the rest of the section.

	The Eagle touched down at 20:17 UTC on July 20. The step at 02:56:15 UTC on July 21 was approximately 6 hours and 39 minutes after landing — which "six and a half hours" (in the body) approximates reasonably, but which "approximately six hours" (in the lead) understates by roughly 39 minutes. The two figures in the article — "six hours" and "six and a half hours" — are inconsistent with each other. "Approximately six hours" and "six and a half hours" are not the same approximation of the same event, and the lead should be updated to match the more precise figure given in the body.

			== Ranger 8 called a "lander" and its location called a "crash site" in consecutive sentences ==

			In the "Launch and flight to lunar orbit" section, the same paragraph uses contradictory terminology for Ranger 8:

			'''Sentence 1:''' "The site was selected in part because it had been characterized as relatively flat and smooth by the automated '''Ranger 8 and Surveyor 5 landers''' and the Lunar Orbiter mapping spacecraft…"

			'''Sentence 2:''' "It lay about 25 kilometers (16 mi) southeast of the Surveyor 5 '''landing site''', and 68 kilometers (42 mi) southwest of '''Ranger 8's crash site'''."

			Grouping Ranger 8 with Surveyor 5 as "landers" is misleading: Surveyor 5 was a genuine [[Surveyor program\|soft lander]], while Ranger 8 was a [[Ranger program\|hard impactor]] deliberately designed to crash into the Moon while transmitting close-up photographs.

Rome: /* Lead says Armstrong walked 'approximately six hours' after landing; body says 'six and a half hours' — 30-minute gap */ new section

Lead says Armstrong walked 'approximately six hours' after landing; body says 'six and a half hours' — 30-minute gap: new section

New page

== Lead says Armstrong walked 'approximately six hours' after landing; body says 'six and a half hours' — 30-minute gap ==

The article gives two different elapsed times between landing and Armstrong's first step on the lunar surface, and they differ by thirty minutes.

The lead section states: "Armstrong became the first human to walk on the Moon '''approximately six hours''' after landing."

The detailed mission narrative gives the actual time of the step as 02:56:15 UTC, and describes this as "'''six and a half hours''' after landing."

The Eagle touched down at 20:17 UTC on July 20. The step at 02:56:15 UTC on July 21 was approximately 6 hours and 39 minutes after landing — which "six and a half hours" (in the body) approximates reasonably, but which "approximately six hours" (in the lead) understates by roughly 39 minutes.

"Approximately six hours" and "six and a half hours" are not the same approximation of the same event, and the lead should be updated to match the more precise figure given in the body.
