According to a news release, the two-stage rocket has nine 3D-printed Aeon engines on its first stage and one Aeon Vac on its second.
“Like its structure, all Relativity engines are entirely 3D printed and use liquid oxygen and liquid natural gas, which are not only the best for rocket propulsion, but also for reusability, and the easiest to eventually transition to methane on Mars,” the release said.
Wednesday’s launch was scrubbed because of a temperature issue with the rocket’s liquid engine.

Relativity Space has released a breakdown of what caused the launch to abort Saturday.
During the first abort, a corner case in the stage separation caused an abort at T 0.5 seconds. Once the new T-0 time was announced, it was an instantaneous window during the last minute of the launch window. The fuel pressure was low during the second abort.
