Default Did Apollo do a burn prior to re-entry?

"PP" wrote in message


to slow it down? It was going , what, about 25,000 MPH?

Or did it "crash" squarely enough into the atmosphere that it didn't
need to?


Coasting in from the moon's L1, being roughly 325,740 km away from
Earth, say passing through that nullification point at something better
than a km/s, you'd think that our return velocity prior to atmospheric
reentry would have become impressive, to say the least.

Too bad there's not a computer simulator for running off such complex
orbital mechanic stuff, such as in 3D animation format with the time
compressed at 60:1 or even 3600:1. Perhaps China or India can
accommodate such basic needs.
