> Is farming really dead?

No, there's plenty of research to make agriculture (industrial and subsistence farming) more efficient. But it's not trivial getting it into the hands and heads of people since you can only do that locally.

No. Nasa and noaa are contributing some parts to a larger machinery. It is not the sole purpose of space missions, but it is a synergetic effect. You need weather forecasts to optimize farming, satellites help with that. GPS helps with international trade which in small part also covers shipping of fertilizer or pesticides to countries.
