Panspermia certain expands the time window, but does not address the question of abiogenesis.
There are two possible answers though (perhaps more than two).
It could well be that given the suitable conditions, the transition of non-life to life has a very high probability. I personally think we will find that to be the case. Once the first life is produced in a lab, I expect there will be a flurry of additional methods found. That is only a personal opinion but it is based on what has happened in the past. Almost every advancement in chemistry (and in the end abiogenesis will be a chemistry issue) shows that there are multiple ways to get the same results.
A second possibility will be if we find that the conditions that do result in the transition from non-life to life are such that it could not happen on a terrestrial body. For example we may find that a condition of low gravity is needed or an absence of a magnetic field. We may even find that the type of life that results is dependent on orientation of magnetic field or gravity levels.
The key event that will support panspermia IMHO will be finding non-terrestrial life forms. It will be particularly interesting if we find life forms that are fundamentally different than the sample we know.
