How do you engineer for space? Increasing telomere length is merely a stop-gap. Random mutations due to solar radiation are exactly the mechanism that evolution exploits to make progress (as well as other sources of entropy), the chemical makeup of DNA is poorly suited to space travel: you can't just genetically engineer that way.
