He left the scene after "answering" Himon's distress call about Mantis's and Kalibak's invasion attempt. He went to the moon after. It wouldn't be hard for him to travel quickly since they use boom tubes. Plus some time passed since the story continued as Superman was waking up from the explosion.

Eh, it was the same blast which killed Mantis and Kalibak and left a trail of astro force to the moon where Orion was standing for quite some time. It was a perfect set up by Infinity Man.
Anyway, Superman was already damn near unconscious by an amped Kalibak's suckershot.
It didn't kill Mantis and Kalibak. Only explanation was Himon(Infinity Man) must've plucked their hearts(souls) out while they were still unconscious. He used Orion as a means of distraction and later confusion as to who the real killer was.
