It's an engine which uses a combination of liquified H2 and O2 (oxidising agent) as fuel, which is why the temprature has to be maintained below -252 C, to keep the hydrogen from boiling. PVJ(Talk)(Articles I have written) 11:46, 29 October 2006 (UTC)
 * The source states that it is the "first test of the cryogenic stage of a rocket engine" - the title and article text is a bit misleading. --Skenmy(t•c•w•i) 09:29, 29 October 2006 (UTC)
