Chandrayaan-1 crashes into the Moon

Joining the rank of previous lunar impactors, the Moon Impact Probe from India's Chandrayaan-1 has successfully crashed into the Moon. Now which country will be next to join the club of nations that have sent probes to the Moon? And how long will it take for India to send a successful lunar lander?

One thing I haven't heard much about is new scientific results from the impactor. I wonder how they would compare with those that we'll get from LCROSS next year?
