As reported by The Register, Japan's Hayabusa 2 mission to mine (or at least sample) an asteroid, which was to have been launched Saturday, has been delayed by weather, until a time no earlier than Monday, Dec. 1st (and from JAXA's web site, it appears that Dec. 3rd is the current target): If all goes to plan, the space probe will lift off next month and fly out to asteroid 1999JU3 by mid-2018 using ion engines. The craft will orbit the rock before dropping a bomb onto the surface. The resulting blast should leave a hole [in] the asteroid. The probe will then land and dig around in the rubble for material from below the surface using a "sampler horn". The probe will then take off again and head for home carrying its booty, and is due to return in 2020 or slightly later.
