when is the next google shuttle

It should be open for submissions next week unless the schedule slips, and it will close in early June.

thanks sir i saw in fossi video that in december too we have shuttle scheduled,is it true.

Yes, but that date is much less certain.

ok like i wanted to know even i miss the second shuttle is third shuttle too will be there or not

As far as I am aware, Google has budgeted the third shuttle run, so it's definitely going to happen.
