I don’t have live tool access right now to pull the very latest articles, but I can summarize the general context on Apollo 10 reentry speed and what recent reports typically note.
- Apollo 10 reentered from lunar return at about 11,000 m/s (roughly 39,000 km/h or ~24,000 mph) at Entry Interface, which is among the fastest sustained reentry speeds for crewed missions in NASA history. This figure is widely cited in historical sources and flight journals and remains the baseline for Apollo 10’s reentry profile.[3][7]
- In-flight data from Apollo-era missions show the spacecraft approaching reentry with velocities in the 11–11.1 km/s range just before interface, with peak heating and deceleration occurring as the capsule traverses denser atmosphere. Apollo 10 and neighboring missions’ flight journals discuss planned entry angles and anticipated g-loads to balance heat shield limits with safe deceleration.[5][3]
- Contemporary missions (like Artemis II) discuss reentry speeds on the order of 34,000–35,000 ft/s (about 10,400–10,700 m/s) in early previews, which are broadly comparable in scale to historical human reentries, though exact numbers depend on mission profile. Recent visual and media coverage of reentry emphasizes the heat shield’s performance under high thermal loads and the resulting splashdown dynamics, echoing what Apollo-era missions experienced.[4][6]
If you’d like, I can:
- Narrow to a specific date range or source (NASA flight journals, Apollo 10 technical debriefs).
- Pull a concise, up-to-date summary with citations once I have access to live sources.
- Create a quick chart comparing reported reentry speeds across Apollo missions and Artemis tests using a small dataset.

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.
