NASA Tests Engine Technology for Landing Astronauts on the Moon

The CECE is based on the existing Pratt & Whitney Rocketdyne RL10
upper stage rocket engine. Previous first-hand flight experience, as
well as this data, will allow engineers to develop simulation models
that can focus testing for efficiency and effectiveness.

Proving once again that the RL10 is the workhorse of US vacuum rocket
engines. :-)

This thing had a lot to do with its creation, as it used the hydrogen
expander cycle to drive it:

Our Net Nanny here at work does not allow bablefish to come through, but I
was able to figure out that you're pointing to this site:

http://xplanes.free.fr/suntan/cl400-10.html

The technology developed for Suntan engine did directly impact the design of
the RL-10.

That's the page alright; the picture of the spiraled heat exchanger is
particularly interesting.
There's more stuff (in English) he
