I don’t have live access to current news feeds right now, but here’s what is established about Apollo 10’s reentry speed from reliable historical sources.
Direct answer
- Apollo 10’s reentry speed at Entry Interface was about 11,070 m/s (roughly 39,800 km/h or 24,700 mph), making it one of the fastest manned reentries in history.
Context and sources
- NASA Flight Journal entries for Apollo 10 describe the velocity progression toward entry and provide figures in the 11,000 m/s range near Entry Interface, consistent with the high-speed reentry profile for a lunar return [NASA Apollo 10 Flight Journal - Day 9, Part 34 and Part 35].[2][3]
- An oft-cited summary notes Apollo 10 reentered at just under 40,000 km/h (about 24,791 mph), placing it at or near the record for fastest manned reentry, a claim corroborated by multiple historical summaries and mission overviews [Answers.com Apollo 10 re-entry speed].[1]
Notes
- If you’re looking for the most current interpretations or any recently released declassified details, I can fetch fresh sources and verify against NASA archives.
- If you’d like, I can present a concise comparison table of Apollo reentry speeds from Apollo missions for quick reference.

This velocity will increase dramatically in the last couple of hours prior to Entry Interface. At 2 hours prior to entry, the speed will be about 14,500 feet per second [4,030 m/s]. One half hour later it will have increased by 2,000 feet per second [556 m/s], up to about 16,120 [fps, 4,478 m/s], and in another half hour, 1 hour prior to entry, the velocity will be up to 18,696 feet per second [5,193 m/s]. … 185:41:27 Cernan: OK, Jack.

www.nasa.govApollo 10 was the fourth manned mission in the United States Apollo space program, and the second (after Apollo 8) to orbit the Moon. Launched on May 18, 1969, it was the F mission: a "dress rehearsal" for the first Moon landing, testing all of the components and procedures, just short of actually landing. The Lunar Module (LM) came to within 8.4 nautical miles (Template:Convert/round km) of the lunar surface, the point where the powered descent to the lunar surface would begin. Its...

I didn't mean to hit Command Reset but since there's nothing critical, I'd play with it for a while and get it set up because the first time around it didn't want to acquire. It was banging all over the place when we were trying to come back around, so I thought I'd get you a good lock on. So we're at Reacq narrow plus 30, 270 and youve got them.
