The first Hayabusa spacecraft malfunctioned during the sample collection attempt. It did manage to return several tiny grains of dust from an asteroid despite the sample collection mechanism not operating. There is quite a bit of information about it at wikipedia.

Play whatever semantic games you want, loads of federal money went into developing the private tech instead of going to NASA or other federal tech funding. I'm not saying it was a bad bet, I'm saying is we can't just achieve the same results but adopting similar looking policies except without the money.

Many? There are three Starships ready to launch as soon as they are tested (though they pribably won't be) and one tested and ready for launch next month. SpaceX can build one in about two months now. Starship will be on the moon in two or (more likely) three years. It will probably be launching starlink satellites by year end. Of all the new generation, it is the closest to operation.
