I think it's pretty obvious he didn't. But, let's say he does. What then? Well, if he isn't ripped apart by the slipspace event (he most likely was), and successfully transitions to slipspace, he will die by suffocation after his MJOLNIR runs out of oxygen. Even more likely, is that he will transpire by radiation poisoning before the 90 minutes of oxygen is used up. Anything salvageable from the Corvette and Supercarrier will be rendered completely useless by the radiation of slipspace. The parts will be fried. In addition, the unpredictability of slipspace without a functioning slipspace drive would render any attempt at salvage impossible.

One could say the same about MC after halo3, yet he endured.

Forerunner slipspace technology is vastly more advanced. Their portal networks and grids more stable and consistent.
