The end where V flies into space

+
Hi guys. I didn't quite understand the ending. On the one hand I finished with Panam and the gang where we drive to Arizona. There he may survive because he may get help through Panam's contacts. The other end where Johnny gets our body is clearly the V completely disappears into the Blackwall. Johnny then leads his own life in V's body. But now there is an end where we make an agreement with Arasaka, I think, and fly into space to this one place. But what happens in the end confuses me? V is in astronauts suit and pulls a weapon but at the same time suddenly starts to get air out of his suit? Is he deliberately murdered there by them? Or is that something completely different?
